Why does my knee hurt when i walk 7 months after arthroscopic surgery?

Let me explain: When you have the surgery for cartilage tear, you could also some arthritis in the knee that could the cause of the pain, check with the surgeon for to see if they found any changes in the joint during the arthroscopy.

Arthritis/Chondrosis: It depends on the reason you had surgery. You could have ongoing osteoarthritis that can continue to bother patients after arthroscopy. If you had any chondromalacia that can cause persistent knee discomfort even after arthroscopy also. If you had ligament reconstruction there could be other reasons as well. Any significant functional limitations should be evaluated by your surgeon.
