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.

Yoga vs gym  
Any form of regular exercise is a must for a healthy lifestyle. While some people prefer to work out in a gym, others like the calmness of their own house where they can practice yoga or a walk in the park. Each style of exercise has its own pros and cons. Let's take a look at working out in the gym vs yoga and regular walks.

Benefits of yoga and walking over going to gym:

Good for both - the mind and the body
Yoga is a lifestyle and not merely an exercise routine. Thus, it not only builds and tones muscles but also strengthens your lung capacity, digestive system etc. It is also said to increase the ability of the mind to focus and attentiveness.
You could walk on a treadmill in the gym but taking a walk outdoors does more good to your body. Being with nature when you walk outdoors is known to be an effective stress buster and helps you calm your senses. Walking can also help improve your moods and is a form of treatment for depression as well.

Does not need any special equipment
With yoga, there is no need for weights or special shoes. All you need is a flat, firm surface which could be the carpet in your bedroom or your lawn outdoors. The only equipment you need for a walk is a pair of sturdy, comfortable walking shoes. This makes yoga and walking budget friendly as well compared to gym membership costs.

Can be done anywhere
Since yoga does not need any special equipment, it can be practiced anywhere and at any time. Taking a break from sitting at your desk - try doing pranayam. Keep a pair of walking shoes handy and at lunch break take a quick walk around the block - there's nothing to stop you.

Less chances of injuring yourself
Once again, since yoga does not need specialized weights or equipment, there are less chances of injuring yourself. Yoga also does not focus on speed, allowing you to move comfortably - in a way that your body always feels good.
Walking again is an exercise that allows you to work at your own pace and does not make you compete with others. As long as you see where you are going and avoid walking on tarred surfaces, the chances of injuring yourself while walking are also very low.

Long term weight loss  
A reason most gym enthusiasts prefer a strenuous workout to yoga and walking is faster weight loss. These techniques do help lose weight but the process is slow. However, since this weight has been lost gradually, it is more likely to stay off.

Pain management is an issue that stares back at mankind, irrespective of the underlying health condition. Whether it is a headache or a back pain, burn or fracture, heart attack or cancer, pain is always a symptom. In some cases like migraines, cancer, etc., the pain is chronic and the patient needs to be constantly on the vigil to know when an attack will ensue. This has also put high pressure on the medical fraternity to identify ways that can provide relief to these people. Various methods have been identified, and one of them is the electrotherapy.

What is done?
A few electrical impulses are directed at the area of the pain using a hand-held device. This is similar to providing electric shocks of mild intensity to the affected area (forehead, low back, neck, etc.). What this does is stimulate the nerve endings, improves circulation and muscle strength and promotes bone growth and tissue repair. The end result of all this is overall improved functioning and pain relief. Depending on the actual condition, the sessions will have to be repeated. In some patients, the electrotherapy is used in conjunction with other therapy so that they can go about their routine exercise and pain relief.
The sessions may also have to be repeated as most often these are used in individuals with chronic pain. They are also helpful in providing relief during the acute attacks.

How does it work?
The most common form of electrotherapy is known as TENS, which stands for transcutaneous electrical nerve stimulation. The area to be treated is cleansed with spirit and then small sticky pads are applied through which the electricity is passed. A hand-held device is used, through which electrical impulses are passed to the skin, which stimulates the nerve cells to provide relief from pain. It causes a vibrating and tingling sensation in the treated area. It is believed that it blocks the nerve impulses and therefore provides pain relief. Another theory states that they promote the release of endorphins which are natural painkillers; it is also very effective in case of migraine and sciatica and neck pain where the chronic pain is coupled with acute spurts.

With narcotic painkillers having various side effects, techniques like electrotherapy are gaining popularity. A small catch also is that it does not work for everybody and in most people with back pain, fibromyalgia, and migraines, requires repeat sessions for relief. The cost of each session also needs to be considered against the extent of relief achieved. However, for those whom it works, it is a very good technique for chronic pain control.

Green tea has been promoted as one of the healthiest beverages around. It is made from the same kind of leaves (camellia sinensis) as generic black tea or oolong tea. The primary difference is that while processing the leaves for green tea, the withering and fermentation procedures are avoided, which helps the leaves retain more nutrients. However, green tea comes with quite a few side effects just like ordinary tea or coffee. They are:

1. Digestive problems
Since green tea is not put through the oxidation or fermentation process, the tannins present in the leaves are not removed. Tannins, can cause nausea and constipation by producing more gastric acid. Adding a little milk to your tea might help with this problem.

2. Reduced absorption of iron
Green tea contains catechins- antioxidants, which can block the absorption of iron from food. Iron deficiency has a number of negative impacts, the most threatening one being anemia where red blood cell formation is hindered. Anemia causes fatigue because sufficient oxygen is not circulated throughout the body due to low haemoglobin levels.

3. Problems with the nervous system
Green tea contains caffeine, just like tea or coffee, though its caffeine content is lower. Excessive consumption can lead to insomnia-like tendencies, heightened anxiety, frequent urination, irregular heartbeat, muscle cramps etc.

4. Risks during pregnancy
Caffeine decreases calcium content in the body, leading to weaker bones, which is an alarming symptom in an expecting mother.

Tannins and catechins passed on to breast milk can also block absorption of nutrients like proteins and fats in an infant's system.
