Knee is a hinge joint where the lower leg bone tibia meets the thigh bone femur. During osteoarthritis, cartilage or ligament defects and degenerative arthritis, knee replacement surgery is recommended world-wide to get relief from extreme pain. Knee replacement surgery, also known as knee arthroscopy, is a surgical procedure, in which the affected knee joint is replaced with synthetic material. The most likely candidates for total knee replacement are the patients with severe destruction of the knee joint coupled with progressive pain and impaired function.

Modern technological advances have made computer assisted knee replacement surgery extremely popular around the globe. In this surgery, the surgeon is assisted by a computer to remove the optimum amount and angle of the bone, which otherwise is done by inspecting manually. This is an excellent example of surgery through small incision and it eliminates the chances of human error. A perfect alignment and balance is achieved and hence longevity is also increased to 20 - 30 years. Knee replacement surgery is also specific to gender as the anatomy of male and female patients is different.

There are many types of knee replacements, most common being the total knee replacement or Total Knee Arthroplasty. In addition, there is partial knee replacement, bilateral knee replacement, revision knee replacement and knee arthroscopy.

In knee replacement surgery, the worn out surfaces of joints of knee are replaced with artificial implant of plastic and metal. The lower end of the femur bone is removed and replaced with a metal shell. The upper end of the lower leg bone (tibia) is also removed and replaced with a channelled plastic implant with a metal stem. A plastic ball is also added under the kneecap depending on its condition. These artificial components are commonly referred as prosthesis. The design of these highly flexible implants replicate knee, with the rotating knee replacement implants assist in backward and forward swing of the legs.

Patients whose knee joints have been damaged by either trauma or progressive arthritis should consider total knee replacement surgery. Post-surgical hospital stay after knee joint replacement is usually three to five days. The surgery has a very high success rate and shows dramatic improvement after a month. This improvement is most notable one month or more after surgery. The pain caused by the damaged joint is reduced significantly when the new gliding surface is constructed during surgery. Initially, patient will walk with the help of a walking aid until the knee is able to support full body weight. After six weeks, patient can walk comfortably with minimal assistance. Patients with artificial joints are prescribed to take antibiotics during the course of any elective invasive procedures including dental work. Physiotherapy is an essential part of rehabilitation and it will increase the muscle strength and patient can enjoy most activities, except running and jumping.

Knee Replacement

The human body allows for movement through the complex system of bones, muscles and joints. A break in the bone is medically known as a fracture and can be caused by constant stress, pressure or impact. It is common knowledge that with age, the bone strength decreases and incidence of fractures (osteoporotic fracture) increases. Based on the affected bone and impact, different types of fractures are commonly identified as:

Complete: When the breakage of the bone is complete, producing two or more pieces, it is referred to as a complete fracture.
Incomplete: When the breakage is incomplete, where the bone has cracked, but does not break into pieces, it is known as an incomplete fracture.
Another type would be the open or closed fracture:
Open fracture: When the skin is exposed and the bone breaks through this exposed skin, it is known as compound or open fracture.
Simple or closed fracture: The bone breaks, but the skin continuity is maintained. Again, here are different types including hairline, greenstick, oblique, etc.
What is the reason behind a fracture?
A bone will fracture when force is applied to it that is stronger than the bone itself. A key factor in a bone s susceptibility to fracturing is age. Both children and older people are prone to bone fractures. Children s bones are constantly growing and have not reached their full strength. Elderly people have brittle bones with old age and are prone to develop bone diseases, making them susceptible to fractures.

How they are treated?
Splint and pain medications are commonly used. Closed reduction where the fracture is reduced without opening up the tissues and open reduction, where the tissues are opened up are common approaches to managing fractures.

Can they be prevented?
Especially with children and in the elderly, extra precaution should be taken to avoid any kind of injury and fracture.

Develop an exercise routine to strengthen the muscles
Manage weight
Use the right footwear and exercise gear
Watch your medications (avoid sleep inducing ones)
Increase lighting in the room/home to improve clarity of vision for elderly
Make the home/living area fall-proof by reducing clutter, using railing in the bathroom and bedroom, using rubber mat, etc.
While a fall may seem inevitable, taking the above steps can help reduce the incidence and severity of a fall, thereby minimizing damage.

Bone Fracture - Common Types and How They Can be Prevented?

Osteoporosis is a disease that affects the bones of a patient. This is most commonly found in women, especially in those women who are close to or going through, menopause. Hormonal changes around this period in a woman's life usually lead to various changes in her body. One of these changes include loss of bone tissue which can leave the patient with brittle and weak bones, a condition that is also known as osteoporosis. This condition literally imbibes the word porous, meaning hollow bones. It is born from an acute deficiency of calcium and vitamin D. The DEXA Scan or bone density test, also known as the Dual Energy X-ray Absorptiometry Scan, is one of the most effective tests that can help you in detecting this kind of damage or thinning bones. Here's why.

    Fractures: The DEXA Scan is an important one because it sends low energy beam to areas like your joints and tissues to show how susceptible you are to fractures. It does so by measuring the strength of the tissues as well as the bones to see how brittle they may be.
    Other Ailments: Measuring the thinning of your bones can also point to the presence of other ailments that may have gone unnoticed or undetected, earlier. These can include kidney disease, hyperparathyroidism which happens due to overactive secretions of the said gland, as well as liver disease due a malfunctioning liver, intestinal disease and various disorders in the intestinal tract, and a serious vitamin D deficiency. With this scan, you can get an insight into the other parts of the body affected by the bone density and whether or not they are functioning properly.
    Estrogen: Simply checking the estrogen levels cannot ascertain whether or not you have osteoporosis, as a high estrogen level can be credited to a particularly heavy period cycle. It does not show the bone health the way a DEXA Scan does.
    Easy and Standardised: This method of scanning usually happens with the help of a mounted X ray machine type, hand held gadget which can be extended to conduct the scan. This is an easy and standardised method that releases low levels of radiation which also makes it a healthier option.
    Bone Density Scores: The T Scores and Z scores point towards the bone density and help in diagnosing the condition efficiently. With a systematic scoring system, it is a sure shot test for osteoporosis.

Osteoporosis is a serious condition. The first step in treating the same is to get a detailed scan like the DEXA scan done, so as to test the extent of the bone thinning to ensure that proper and timely treatment takes place.

Why is the DEXA scan important for osteoporosis patients?

Bones are similar to a porous framework which is filled with minerals that make it hard and strong. With age, there is gradual degradation and the mineralized portion is lost, thereby leading to thinning of the bone. The word osteoporosis literally translates to porous bones, which is due to the gradual demineralisation. In addition to the natural ageing process, there are other diseases that can accelerate the demineralization process.

Women are more prone to demineralisation, and after the age of 40, they should take extra precaution to slow down the onset of the condition. The following are some ways to improve bone health and halt osteoporosis in the long run-

Diet: Ensure that your diet has sufficient amounts of vitamin D and calcium. Though calcium is the essential mineral for bone formation, vitamin D is required for the absorption of calcium, and therefore both these elements play a vital role in maintaining the quality of the bones in our body. Most people require about 1,000 mg of calcium and about 500 units of vitamin D for optimal bone health. This requirement goes up slightly in postmenopausal women.

Sun Exposure: In most people, exposure to the sun allows the body to make vitamin D, but careful sun protection prevents this from happening. Also, with age, the body s ability to form intrinsic vitamin D also declines. The body, therefore, relies on supplements. Most dairy products are good sources of calcium. In addition, spinach, salmon, turnips, and broccoli are some calcium-rich foods. Supplements of calcium carbonate or calcium citrate can be taken if your diet is lacking in calcium. Vitamin D also should be included in the supplementation. The treatment for osteoporosis is incomplete without these two supplements.

Exercise With Weights: The constructive tension that exercise puts on the body helps in bone building, whatever the age may be, which prevents the onset of osteoporosis. Any exercise which improves muscle mass strengthens the bones, and puts stress on the bones is advisable. Since the fractured area due to osteoporosis mainly includes the spine, lower back exercises, yoga, tai chi, and abdominal exercises all work wonders. Pick any of these and do them for 30 minutes three times a week.

Quit Smoking: Continuing to smoke while taking osteoporosis medications is completely useless. Nicotine negates all the effects which defeat the purpose of taking the medication and is as good as taking no medication at all. So if you want the bone thinning to stop, stop smoking.

Alcohol Consumption: While a drink or two per week is permissible, more than this can harm the bones significantly.

Constant Health Watch: Talk to your doctor about how other routine medications (if any) can affect your bone health. Also, identify how frequently you should check your bone mineral density and stick to the schedule.

Bone health and osteoporosis can be managed with some conscious efforts.

Knee pain is one of the most common and painful ailments that can limit mobility. Injuries can result in cartilage or meniscal tears or sprains too. Obesity is another reason because of which knee pain is on the rise. Also, regular wear and tear of ligaments and tendons around the knees due to old age is another cause. These days, with reduced physical activities and sedentary lifestyles, the rate at which knees are wearing out has also become accelerated. Whatever the reason, a correct diagnosis followed by prompt treatment can help. Over the years, physiotherapy has been playing an important role in treating knee injuries. Whether to supplement the various drugs to reduce pain and inflammation or to avoid surgery, physiotherapy has helped many and its popularity is growing every day. Here are some ways that physiotherapy can help reduce pain.

Improve flexibility of tendons: The knee cap is an area where there are lot of tendons and ligaments, coordinating to enable movement. Careful exercising can ensure that the flexibility of tendons and ligaments is improved, thereby making your knee movement easier and less painful.
Improves blood supply: As we all know, proper movement requires good blood supply. Exercising with special focus on the knee ensures that blood supply is improved, and thereby the supporting ligaments and tendons function optimally.
Enhances the knee cap function: The knee cap is that portion which joins your thigh bone to your calf bones. This is prone to slip out of place, especially with arthritis and injuries. This can be painful and limit movement to a great degree. Focused exercises aimed at improving knee cap function will ensure that the knee cap has a wider range of function, and does not slip out of its socket easily.
Reduce rigidity: Once you start physiotherapy, you will feel your knees getting more flexible. The rigidity that had set in as a result of injuries and/or old age will also reduce over a period of time.
Slow down the wear and tear: When you start physiotherapy after knee damage, continuing the exercise routine, of course with expert guidance, can reduce the pace at which further damage might happen. A word of caution though. Be sure to consult an experienced physiotherapist before you begin. Exercising in a bad manner can do equal or more harm than the original injury or old age itself.

Knee Pain and Physiotherapy

Calcium is known for its role in maintaining the bone health, from keeping your teeth stronger to normal functioning of the cells.  But there are various factors, which lead to a deficiency of calcium in the human body and paves the way for several complications.

Here are the top three signs that indicate you are suffering from calcium deficiency.

Difficulty in sleeping: Sleep is essential for your bone health and calcium is directly associated with your sleep cycle. The level of calcium in your bones rises and falls when you are asleep and it reaches its peak when you are in deep slumber. This indicates that when you are unable to sleep properly, it is a warning sign of calcium deficiency. There are various researches that have confirmed, that by increasing the level of calcium, it is possible to restore the normal sleep cycle of an individual. This is also related to the role that calcium plays in the production of a sleep hormone called melatonin. When the calcium content in the body is really low, this hormone is not produced, thus, making it difficult for a person to sleep.
Difficulty in losing extra pounds: Yet another frustrating aspect of any individual s life is the inability to shed off excess pounds. This issue is also linked with the lack of calcium supply in the body. The calcium that s stored in the cells assists in the processing and storage of fat. So the fat cells with high calcium content burn faster, making you lose weight. Thus, if you have trouble losing weight in spite of having a well-regulated diet and regular workout, it s a sign that you are suffering from low calcium.
Paresthesia: Though this ailment is not much heard of, it could be a sign of calcium deficiency. Paresthesia is a nervous disorder, which causes tingling sensation, tremors, numbness and loss of sensitivity. It could also lead to poor concentration, amnesia, confusion, hearing impairment, twitches and other physical as well as neurological impairment. This is because low calcium in the blood is connected with the health of your nerves.
The deficiency of calcium can manifest itself in different intensity, ranging from the non-existent to minimal to severe levels. Chronic calcium deficiency can lead to life-threatening diseases like rickets, osteopenia, and even osteoporosis. Therefore, you shouldn t ignore these signs and consult an expert without delay.
