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. I will advise to do X ray knee and if required MRI knee can be done and if there is severe destruction of menisci then arthroscopic shaving can be done. Physiotherapy like ultrasound and tens will help, along with knee exercises . Life style changes will help in reducing pain which include, 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. 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.
