Q.1 Things not to be done after a complete knee replacement surgery?
Even though your activity level is likely to increase, a knee replacement surgery means that high-demand or high-impact activities must be avoided. You should definitely avoid running or jogging, contact sports, jumping sports, and high impact aerobics. You should also try to avoid vigorous walking or hiking, skiing, tennis, repetitive lifting exceeding 50 pounds, and repetitive aerobic stair climbing. The safest aerobic exercise is biking (stationary or traditional) because it places very little stress on the knee joint.
Q.2 Knee or joint problems occur in women after some age, why?
A recent study in The New England Journal of Medicine showed that while women are more likely to suffer from arthritis than men, they are three times less likely to undergo knee replacement to relieve their pain. If you're a woman suffering from chronic knee pain, you may often notice how this pain affects your daily activities such as walking or enjoying family events, and it may even be disrupting your sleep. Yet as a woman, you may often wait to seek treatment due to the uncertainty of the recovery period and how it may impact your life and family. When non-surgical treatments such as exercise or anti-inflammatory medications no longer relieve your pain and your knee dictates what you can and cannot do, it is time to talk to your orthopaedic surgeon about knee replacement surgery.

Q.4 What to do with rheumatoid arthritis?
Unlike osteoarthritis, Rheumatoid knee arthritis involves inflammation of the lining of the joints, known as the synovium. Though less common than osteoarthritis, rheumatoid arthritis is among the most debilitating of the over one hundred forms of arthritis. Rheumatoid arthritis usually develops in middle age, but may occur in the 20s and 30s.
Treatment of rheumatoid arthritis usually involves medications such as NSAIDs, aspirin and analgesics. In severe cases, surgery may be indicated to replace the knee joint with an artificial joint. If you think you may have arthritis of the knee, contact your doctor for a complete evaluation and a discussion of the options available for treatment.
