After four months of knee joint release, the knee joint still can't straighten and bend normally. How long will it take to get back to normal completely?

This situation is still unable to flex after the release operation, which is generally caused by local adhesion after the operation. There was still no active exercise in the early days.

Suggestion:

Generally speaking, the effect of doing exercise after four months is not very good. If there is obvious improvement after operation, you can use external application of traditional Chinese medicine for promoting blood circulation and removing blood stasis, physical therapy, massage and other rehabilitation treatments. It is difficult to fully recover.
