Knee Arthroscopy

Arthroscopy is a procedure in which the inside of a joint is visualised using advance camera and lighting equipment. Technology has allowed both the camera and the light source to be incorporated in a thin tube. This tube can be introduced inside the joint through a very small incision or cut. The name key-hole surgery has been coined for arthroscopy as it is minimally invasive. Knee arthroscopy has many advantages. The interior of the joint can be completely visualised by this procedure. As it doesn't require a lot of skin and tissue cutting, it can be used as a diagnostic tool. Because the arthroscope tube is thin, we can visualise areas at the back of the knee which are difficult to see in open surgery.  As the surgery is done through small holes, postoperative pain is minimal and recovery is very quick.

Knee arthroscopy has revolutionised treatment of certain problems. A classic example is synovitis or thickening of the lining of the knee. Synovitis can happen due to various reasons. Sometimes it is necessary to remove a part of the synovium (or lining) as a biopsy. In other cases it is required to remove the entire lining as treatment. Formal open synovectomy (or removal of lining) was a major surgery that led to postoperative pain and knee stiffness. Besides some synovium would remain behind at the back of the knee due to difficult access. With arthroscopy, total synovectomy can be achieved with minimal pain and stiffness.
Another area where arthroscopy has made tremendous progress is in the field of ligament and meniscal injury. The commonest ligament which gets injured during a sport or road traffic accident is called the anterior cruciate ligament (ACL). Once this ligament is injured, it leads to instability. The patients knee buckles every now and then and he/she loses balance and may fall. The patients describe the problem as a 'wobbly knee' and get a typical 'giving way' sensation in the knee. These repeated instability episodes eventually wear out the knee and patients end up with knee arthritis in a few years. In earlier times there was no good solution for this problem. Open ligament reconstruction procedures were fought with failure. All this changed with the advent of arthroscopy. Nowadays arthroscopic ligament reconstruction has become an extremely successful procedure. The patients own hamstring muscle tendon is harvested and a new ligament is made by folding the tendon on itself. This new ligament is then fixed into pre-drilled tunnels in the patients thigh and leg bone to become the new ACL ligament. This eliminates instability so efficiently that patients can start playing contact sports like football after the procedure. The patients knee is restored to its original state and any further wear and tear is arrested. It has now been proved beyond doubt, in multiple studies done internationally that results of ACL reconstruction are much better than non surgical treatment.

The meniscus is a thick structure found inside the knee joint which acts like a shock absorber. Just like the ligaments, the meniscus can also tear due to injury. A meniscal tear classically causes pain and locking of the knee. The locking occurs because the torn meniscal fragment gets stuck between the two bones. Repeated locking episodes lead to pain and swelling. Before the advent of arthroscopy, it was very difficult to treat meniscal tears. Surgeons ended up removing the entire meniscus which was not only unnecessary but also harmful as it lead to early degeneration of the knee. With arthroscopy it is now possible to tackle only the torn fragment. Either the torn part is removed and the rest of the meniscus is left behind or the torn fragment is repaired. Again arthroscopy allows the knee to be restored to its original state.

Arthroscopy is a major advance in orthopaedics and it is now being successfully utilised in solving problems of other joints as well like the shoulder. Patients should be aware of the benefits of arthroscopy and must take advantage of this science when required.

We have all heard about osteoporosis or weakening of bones as we age. Many of us have done bone density tests and are taking supplements to prevent or treat osteoporosis. But what is sarcopenia? Sarcopenia is a loss of muscle mass that occurs as we age. As we mature into adults, hormonal changes ensure optimal muscle mass by the age of 25. But this muscle doesn’t remain constant with us throughout life. For those who lead a sedentary lifestyle, muscle loss starts as early as at the age of 30. Typically an inactive person loses up to 5% of muscle mass per decade.

What happens when we lose muscle? First and foremost a weak muscle offers poor protection to its neighbouring joint. Joints need strong muscles to function properly and durably for many years. When muscles are weak, the joints become vulnerable to damage. This damage can happen in any joint, but typically it is seen in the knee joint, the neck and the lower back. Initially patients complain of only occasional pain. Painful joints are instinctively rested by the patient. The rest worsens sarcopenia. This in turn predisposes the joint to even more damage. Thus the pain sets up a vicious cycle. This cycle ends in osteoarthritis of the knee or spondylitis of the neck or back, which in its last stages requires surgical treatment. 

Loss of muscle also results in a lower basal metabolic rate (BMR). In simple words, the body is unable to burn calories efficiently. Lower BMR combined with a modern high calorie diet leads to increase in body fat. Excess fat increases insulin resistance. The end result is central obesity or a pot belly with diabetes, coronary heart disease (heart attack) and hypertension (high blood pressure).

End stage sarcopenia which occurs in elderly patients results in frailty, loss of balance & frequent falls. Sarcopenia is thus responsible for not only musculo-skeletal problems like osteoarthritis and fractures but also life style illness' like diabetes.

Is sarcopenia preventable or treatable? The good news is that it is! We can slow down the loss of muscle that happens with age by making positive changes in our diet and lifestyle. If we work a muscle, it will respond by a tear - repair mechanism to become stronger and a stronger muscle means a reversal of sarcopenia. The best way to strengthen a muscle is by doing resistance training. This can be done by either lifting weights like dumbbells or by using our own body weight. Typical body weight exercises are squats, push ups and lunges. As sarcopenia affects all muscle groups, it is important to work out all muscle groups. We must exercise not only thigh and calf muscles but also chest, back, upper limb and abdominal muscles. Walking is not a good exercise for sarcopenia as it works out only leg muscles and it is not a resistance training exercise.

Diet is as important in the prevention of sarcopenia. For muscles to repair and become stronger they need protein as a raw material. Protein is essential in a healthy diet. We must ensure adequate protein intake. A normal adult requires 0•8 gm of protein per kilo of body weight per day. Meat, eggs and dairy products are rich sources of protein. Roasted, boiled or baked chicken or fish are the healthiest source of meat protein. Milk, cheese and yogurt are good dairy sources. Vegetarian sources of protein include beans, lentils, green peas, chickpeas, soy, spinach, asparagus and brocolli. Nuts like almonds and peanuts also contain protein. Fruits can also provide protein with the richest sources being guavas, berries and apricots. To be effective, a high protein diet must go hand in hand with a low carbohydrate, low sugar and low fat diet.

A lot of research is going on but there still is no medicine that can stop or reverse sarcopenia. Exercise and diet remain the key to prevention as well as cure. We must eat clean and exercise hard to remain healthy and keep illness at bay. We really have no choice!

Which exercise is best for weight loss?

We now know that obesity is a problem. The pot belly is a house of disease. Obesity and high blood pressure go hand in hand. So do obesity and diabetes and obesity and coronary heart disease (chest pain and heart attack). Losing weight is the need of the hour. Weight loss is no more a goal for mere good looks. It is essential if one wants to lead a healthy life.

Diet is the key to weight loss. I have written on diet and weight loss, the pot belly and the evils of sugar. For some people, diet alone may not be enough. Their basal metabolic rate (B.M.R) is so low that changes in food habits are not enough to bring about the weight loss. In simple words they are just not burning enough calories. The fat burning engines of their body have gone to sleep. Exercise is the only way to increase their metabolic rate.

All of us think of walking when we are considering exercise. We feel it is the best exercise to do the job. In fact it is the first exercise that comes to our mind. Many of us have taken up walking only to give it up after a few months or weeks. Many of us have stuck to walking for years. But how many have really succeeded in losing weight by walking alone? Probably very few. All our life we have been brain washed by health experts, doctors and dieticians into thinking that walking is the best exercise. Gyms spend crores on treadmills and have entire sections dedicated to cardio. Those who can walk are encouraged to jog and even run. Marathons have evolved from a sporting competition to the new health fashion! But alas, all this is far from the truth!

Walking is not the best exercise to lose weight. Walking falls in the category of what experts call 'steady state cardio'. Walking is a basic life function and the body has evolved over the years to make it very energy efficient. So not enough muscle groups get involved when we walk. If we walk for longer distances then the muscles quickly adapt and become more energy efficient. A similar process happens when one jogs or runs at a constant pace. That's why we feel tired or get palpitations (can feel our heart beating) only for a few of the initial walks. After a week or so of walking, we can walk the same distance with ease. An energy efficient muscle will conserve calories and not burn them! However for patients with existing heart problems, walking remains a good exercise. They require an exercise that will put less strain on the heart. Heart patients should not try any other exercise without consulting their physician.

Which are then the best exercises to lose weight? To lose weight we must increase our metabolic rate. That will happen when large groups of muscles work hard. To achieve this we must do the opposite of steady state cardio. It is called High Intensity Interval Training (HIIT). As the name suggests periods of high intensity workouts should alternate with short intervals of rest. If you choose to exercise on a treadmill, then short bursts of brisk walking should alternate with short periods of walking slowly. People who are more fit, can do bursts of sprinting alternating with intervals of slow jogging. A similar interval training can be done in cycling and swimming. These short bursts require the muscles to work hard. By pushing the muscles out of their comfort zone we can force them to become calorie hungry. Metabolic rate and calorie burn is thereby increased.

Another way to lose weight efficiently is by weight training. By lifting weights we can exercise large muscles of the body and the exercise is not restricted to only a few muscle groups. The entire body musculature gets involved. Furthermore by pushing the muscles to their limits, there is a tremendous increase in calorie burn which lasts throughout the day as the muscles recover. We can thus achieve a sustained rise in metabolic rate. Weight training is perhaps the most efficient way to increase metabolism. 

Boot Camp exercises or Body Weight training is an alternative for those who cannot join a gym. These are sets of exercises which make use of the body weight instead of dumbbells and machines. Examples of such exercises include squats, dips, lunges and burpees. Quick sets of such exercises performed with short breaks are effective in achieving a higher metabolic rate.

Losing weight is all about diet for most of us. Both quality and quantity is important. For some people changes in diet are not enough. They need to fire up their metabolic engines to burn up those calories. Age old beliefs of types of food which increase weight, have recently been proven to be wrong. Similarly its time for a paradigm shift in our ideas about exercise. The words cholesterol and walking have now been replaced by sugar and HIIT!

The Not So Sweet Reality

Lets introspect on how things were a half century ago. At that time people consumed lots of fat, butter and pure ghee. Sweets were eaten rarely and the sweetener used was honey. Ninety percent of the food that people ate was cooked at home. The fast food industry was nearly non existent and there were few available brands of biscuits, potato chips, cakes, mithai, chiwda, chocolates, colas or ice cream. Going out to eat ice cream would be nothing less than a family event which would be fondly remembered for days. A box of mithai would come home but once in months. All of these snacks were consumed rarely! Restaurants were few and going out to eat was infrequent. Also infrequent at the time were here heart attacks, blood pressure, obesity and diabetes.

Then cholesterol was identified as the substance which was found in blocked blood vessels. This lead to a diet revolution based on fear. We were told that dietary cholesterol is bad for our health. We started avoiding fatty foods like cheese and butter, oily food or deep fried food. We didn't eat the egg yolk and only preferred the egg white. At a restaurant we started to ask for normal roti and not 'butter-roti'. We would frown if we saw a dish with excessive oil. This movement against fats and oil tilted the diet towards carbohydrates. Slowly but surely diets around the world became carbohydrate rich.

Simultaneously there was a surge in the economy and people's spending power increased. The food industry expanded and packaged foods and fast food became affordable. Refined sugar and refined flour became the main ingredients of these snacks. What was a luxury enjoyed once in many months, could now be easily consumed every week or even every day. Today, the smallest event is celebrated by cutting a cake. Home refrigerators are loaded with ice creams and colas. They have become oft consumed midnight snacks. Historically sugar consumption has increased from barely 2kg per person per year in the eighteen century to a whopping 70kg per person per year in the twenty first century. Calorie intakes have increased but physical activity has reduced. People are enjoying a sedentary lifestyle. With elevators and cars there is no need to exert. What has also increased unfortunately are the rates of obesity. People are developing pot bellies more than ever before. Low fat and high carbohydrate diets are not having the desired effect that was hoped for. In fact the absolute opposite is happening. Along with obesity, rates of blood pressure, diabetes and heart disease are up.

Only recently, the veil has been lifted. It is not fat, butter or cholesterol that is the real devil. It is the carbohydrates, especially the simple ones like refined sugar and foods that contain large quantities of this sugar. To reduce the rates of obesity, diabetes and heart disease we must re-adopt the lifestyle our ancestors. We have to change the way we think about food. It is time for a paradigm shift. We should not consume sugary drinks like colas, tang, rasna or sugary tea. They are directly linked to obesity and therefore many diseases. Biscuits are a strict no, at least not daily. We can eat a biscuit, or a piece of cake, or a few chips once in a while. Jam is full of sugar and we must stay away. Same is true with tomato ketchup. Snacks and mithai must be consumed only occasionally. On the same note, we must not eat out often. It is desirable to stick to home cooked food made with hand picked, quality ingredients. In addition to simple sugar, we must eat less quantities of starchy foods like potato, maida, rice and bread.

Sugar from a cola or an ice cream or a chocolate is easily digested and quickly absorbed in the blood stream. This puts a strain on the pancreas to produce a large quantity of insulin. This insulin in turn reduces the sugar in the blood by converting it into fat. Moreover it makes you hungry and you end up eating more food. Regular high sugar consumption literally burns out the pancreas and the end result is diabetes.

Along with diet we must re-adopt the physical activity of our ancestors. We must exercise by going to the gym, walking, cycling, swimming or similar activity. The best results are seen with weight training either in the gym or by using body weight (push ups, dips, squats etc).

In conclusion, sugar is the real problem. Lots of sugar indirectly enters our system through packaged foods. We must make it a habit to read the ingredients before we consume any foodstuff. Our food should come from our own kitchens and not from restaurants, bakeries or factories. Carbohydrates are the new enemy!

The Pot Belly - a sign of prosperity ..... think again!

It's customary in India to see a man with a pot belly/paunch and say "it's a sign of prosperity". The origins of this comment are deep routed. Weight loss is associated with illness. Weight gain is associated with newly acquired wealth and hence access to richer foods. In addition a typical Indian mother is obsessed with feeding her children. A rolly-polly child seems to bring immense satisfaction to his/her mother. She feels she is doing her job well. This obsession continues even when the children become adults. If an adult male loses weight it is assumed that his wife/mother is not looking after him. To his/her friends and family, a person's pot belly is accepted easily. It's hardly a matter of concern! It's to be joked about and forgotten. 

The truth couldn't be further from this. The pot belly is the root cause of all health issues today. It's literally a house of disease. It will bring in its wake horrendous illness' like blood pressure, diabetes and the dreaded coronary heart disease (heart attack).  It is a measure of a persons lack of physical fitness. People with pot bellies are more prone to back pain (lumbar spondylitis) and knee pain (osteoarthritis). It is also a direct indicator of a persons unhealthy eating habits. 

Pot bellies were not so common until recently. Why didn't our ancestors have a pot belly? What are we doing wrong? Our fore-fathers did a lot of physical activity. No access to vehicles meant they were walking a lot. No elevator meant they were climbing stairs. They were lifting their own bags. They were using cycles and not motor-cycles. They had to walk to the market to buy their vegetables, walk to pay their bills and walk to the bank. With the progress in technology, mobile phones and internet, we are doing everything from the comfort of our home or office. The result is a near complete lack of physical activity. That is not all. There is a change in diet patterns. Our fore-fathers ate natural and home made food. Going to a hotel to eat food was not even a monthly event let alone every week or every day. There were no fancy bakery products like cakes, biscuits, toasts, etc etc. There was no packaged food industry and therefore no (or less) chocolates, sweets, ice creams, colas, chips, chevda, mad angles, etc etc. As a result, people in those days did hard physical work and ate healthy food. So it comes as no surprise that in today's day and age, the pot belly is common and so are lifestyle illness' like diabetes etc. 

The new age brought with it a food evolution. Sugar became the new mantra. Adding sugar made food tasty and easier to sell. As a result packaged food items associated with with wealth like chocolates and colas were packed with sugar. In fact most packaged food items contain sugar. May it be a seemingly harmless biscuit or apparently healthy cornflakes. This kind of sugar is hidden and we don't know about it till we read the ingredients. Only recently research has shown a direct correlation with sugar intake and obesity. 

Now it becomes clear ..... A paunch is truly a sign of prosperity as only the wealthy can indulge in these expensive packaged sugar products. And the whole food and advertising industry wants you to spend money on these food stuffs. The newspaper is full of the adverts and so is the television. Gullible people like us are falling prey. They are doing exactly what the adverts tell them to do. Biscuits, jams, chocolates have become part of our lifestyle. We cannot imagine a world without them. 

We need to wake up and realise how foolish we have been. We need to go back to the ways of our ancestors. We need to say no to the cola and yes to a walk. We need to look down on our pot belly and get rid of it immediately. We need to caution our friends and relatives and inspire them to get rid of theirs. A pot belly is a recipe for disaster and no trivial joking matter. 

It is now time for a paradigm shift. Exercise must not be seen as an optional leisure activity that you do if you have spare time. It's a necessary task of daily routine like eating a meal or having a bath. Similarly food must not be viewed as ‘going on a diet to lose weight’ but a healthy, natural (low sugar, low oil) eating habit must be developed as a permanent lifestyle change.

PAINLESS - Total Knee Replacement

Total knee replacement is a highly successful surgery. Patients disabled with knee pain who can barely walk on their deformed legs undergone a dramatic transformation after the surgery. They experience complete relief from pain and complete correction of deformity. After surgery they don't need pain killers. They can walk normally without a stick or walker and at a normal pace. 

However the surgery is a major procedure involving cutting of muscle and bone. This leads to a slow and painful recovery. Post surgery pain after knee replacement can be unbearable and remains as a major deterrent to someone who wants to undergo the operation. Traditional methods of pain control include intravenous or intramuscular analgesic injections and epidural pumps. Intravenous medicines have safety issues and are not effective. Epidural pumps involve placing an epidural catheter (a very thin tube) in the epidural space near the spinal cord. Through this tube medicine is administered which numbs the spinal nerves and relieves pain. A well functioning epidural pump is very effective but has certain problems. Firstly, placing an epidural catheter is a blind procedure and many times the catheter is not in an ideal position. As a result it fails to reduce pain. Secondly, epidural pumps may cause a drop in blood pressure in some patients which requires constant monitoring. Lastly, epidural medicines may cause temporary sensory loss and motor weakness in the legs which makes walking after surgery difficult. 

In recent years, technological advancements in the science of anaesthesia and pain management have made painless knee replacement possible. Patients are standing and walking by evening on the day of surgery! Nerve blocks are a known technique of analgesia (pain relief). Two technologies have become available to the anaesthetist in the operation theatre which have revolutionized the efficacy of nerve blocks. First is a nerve locator. As its name suggests it helps in precisely locating a peripheral nerve which then can be blocked by administrating medicine. Second is portable ultrasound. Combining these technologies increases the accuracy of locating a nerve to 95%. This allows the anaesthetist to confidently block peripheral nerves (nerves outside the spinal cord) with predictable success. In the case of knee replacement, a femoral block and an adductor canal block is used to numb the pain. These blocks are effective and safe. There is no drop in blood pressure and no motor weakness. As a result we have successfully eliminated the need for epidural pumps. 

Another advance that we routinely use is called LIA - Local Infiltration Analgesia. This involves injecting a combination of medicines in the local tissues around the knee joint at the end of the surgery. With modern drugs and optimal doses, this technique alone numbs the knee for 12 to 24 hours. Again the technique is safe and effective. it does not require monitoring of blood pressure and does not cause any weakness. 

The last addition is that of pain patches. Newer opioid analgesics (artificial morphine substitutes) are available as pain patches. A single patch can work for a week. The action is not only long lasting but fast as the medicine is directly absorbed in the blood from the skin (bypassing the stomach). 

Not only is total knee replacement a highly successful surgery, it is now a comfortable and pleasant experience as well. Today’s analgesia is safe and effective. All patients are able to walk on the day after surgery and many manage to walk on the same day. Nerve blocks, LIA and Pain Patches are so effective that they have made painless knee replacement a reality today.

Self Preservation

How often have we seen a personal crisis ruining life? A young man just managing to settle down in life suffers a heart attack! He now faces a prolonged recovery and loses his job. Medical expenses coupled with a loss of income push him into a financial crisis. A young woman juggling her job and family life suffers an accident. A slow recovery means she cannot look after her children. All of us dread a personal crisis but what do we do to prevent it? We must think about self preservation. We must take precautions to avert a potential crisis!

An accident is top on the list. Accidents can occur in a variety of places. They can occur on the road, at home, at work or when travelling. The most common and the most dreaded are road accidents. The road conditions in many developing countries are pathetic and accidents occur rampantly. Yet I see few people thinking about prevention. Wearing a helmet is a simple basic precaution which will save a person from a potentially lethal or paralysing head injury. It is the difference between getting up and walking away from an accident versus an injury which may  lead to permanent disability and handicap if not death. The same applies to wearing a seat belt in a car. Seemingly simple, easy and effective precautions and yet many of us don't do it! Why? Because we don't think about life preservation untill it's too late. Following road rules (like using an indicator or not cutting lanes), avoiding rash driving and speeding, stopping at signals, keeping the vehicle well maintained and regularly serviced go a long way in accident prevention. Talking on the phone while riding a bike or driving a car is another recipe for a catastrophe! What about accidents at home? In the kitchen, be careful with the cooking gas! Old malfunctioning pressure cookers can burst, hurriedly used sharp knives can cut fingers and hot utensils and boiling oil/water can burn. The other danger zone at home is the bathroom. Make sure the bathroom floor is non slippery. There should be support handles for old people to get up. Beware of sharp shelf edges which could injure if one falls.  Don't climb on a chair to reach for a high shelf or clean the fan, use a stable ladder. The same rules apply for the work place or when travelling. We must be extra careful when travelling. An accident in a foreign land can be particularly nasty as we are helpless and often end up with less than ideal medical care.

The next is a medical crisis. We cannot control all the factors that lead to illness! But we can definitely control some of them. Young people get so busy with work and family that they don't have time for health preservation. The modern motto is to work hard now and enjoy the fruits after retirement. But reality is quite the opposite. By the time they retire,  people are bogged down with so many medical problems that their old age is nothing more than suffering, pain, doctors visits and a long list of medicines. Little does one realise that the efforts to achieve a healthy old age need to start when one is young. The idea of an investment which will pay returns in the future appeals to all but they are unable to apply the same logic to health. And yet, the truth is that investing in health remains the most profitable proposition. What factors can one control? Most critical is to stay away from addicting substances like cigarettes, alcohol, tobacco and drugs. These substances guarantee a life of suffering and a miserable old age. Beyond that, a healthy lifestyle boils down to two main factors - diet and exercise. I have written a number of articles on diet and exercise. Interested readers can access them on my blog - A good diet is about good quality foodstuffs and portion control. We must educate ourselves about which food is good for us. We ought to consume more protein and fibre (vegetables and fruits) and less carbohydrates and fats. We need to differentiate between good carbohydrates (chapati) versus not so good carbohydrates (rice) versus bad carbohydrates (potato, bread, maida, cake, jam, biscuits, cold drinks, sugar, mithai, ice cream, bakery products, chocolates and sweets). Stay away from bad carbohydrates. They are poor quality foodstuff. Portion control remains the key to weight reduction. Amount of food to be consumed in each meal should be decided before we start to eat. Eat only small amounts of food for lunch and dinner and compensate by having healthy snacks in between. A heavy meal neutralises the benefit achieved from a long period of starvation or a session of exercise. We must eat slowly to feel satiety with seemingly small quantities of food. Make it a habit to read the ingredients label on food packets to look for hidden sugar. As a thumb rule, food cooked at home will always be healthier than eating out. Be careful when eating outdoors or when travelling as chances of ending up with an upset tummy and loose motions are high. For exercise, do activities that you enjoy! There are no set rules. Choices are plenty from walking, running, cycling, swimming, aerobics, going to the gym or doing yoga. Remember that the only bad workout is the one that didn't happen. Aim to do some exercise for at least half hour, 5 times a week. Ideally one needs to exercise for an hour every day. Today people lead stressful lives, eat poorly, avoid exercise and buy medical insurance. The smart choice would be to work towards health and not ever need insurance.
The last aspect of illness prevention is timely screening for silent diseases and treatment of medical problems. Problems like blood pressure, diabetes and heart disease may not result in any symptoms for many years. An early diagnosis is crucial for preventing permanent damage. So everyone must get themselves screened for these illness' on a regular basis. It does not end with screening. One needs to to take proper treatment of his/her illness. For hypertensive patients, blood pressure should be controlled. For diabetes, blood sugars should be controlled. A diabetic patient must own a home blood sugar testing machine and must check blood sugars every week. Timely and regular intake of medicine coupled with regular testing and doctor's follow up is essential. 

A mention must be made here about the weekend warrior. These are the people who indulge in contact sports like football only on the weekends. Such sports require a high level of physical fitness which can come only with vigorous daily exercise. Those who don't exercise have weak muscles which offer poor protection to the joints. Hence the weekend warrior is much more prone to injury to the shoulder, wrist, knee or ankle than the physically fit person. Those who don't exercise daily are better off avoiding weekend sports.

Self preservation is an awareness that must be cultivated in the mind. A constant vigil will reduce the chances of a potential tragedy. Simply put it is the difference between happiness and suffering. The choice is really ours to make. Is it worth riding a bike for thrills or spending all your time at work or gorging on meals till your shirt buttons pop? We ought to rely on ourselves to look after our health rather than medical insurance ...... prevention will always remain better than cure!!
