Hello, I have studied your case. According to your symptoms and findings there is osteoarthritis of your knee. You can start cartilage protecting medication like chondritin sulphate, that you need to take for couple of months. Physiotherapy like ultrasound and tens will help, along with knee exercises Life style changes will help in reducing pain which include, LOAD REDUCTION : Protecting the joint from excessive load may slow down the rate of cartilage loss. It is also effective in relieving pain. The heavier you are, the more stress you put on your joints. ACTIVITY MODIFICATION -It is important to maintain as much activity and joint motion as possible, but impact activities will aggravate arthritis. Running and jumping will often accelerate cartilage loss from the joint. The key is to focus on low impact activities, such as swimming or cycling. ANALGESIC MEDICATION : Simple over the counter medications like acetaminophen is sufficient in most cases. VISCOSUPPLEMENTATION: Hyaluronic acid injections given into the joint (especially large joints like knee joint) in prescribed dosages will give good short term pain relief in arthritic joints ranging from 1-2 years. If there is no relief with all these procedures then the last option remains of total knee joint replacement.Patient find good difference in mobility after joint replacement.
