Hi, I got my ACL reconstruction done on 15th Nov(2+ months now) with hamsteing autograft. The recovery looked fine up untill now with little pain and stiffness here and there. I have around 95% passive knee flexion now and around 80-90% active flexion while sitting. The recovery till now looked ok with little pain here and there. But from past few days since the time I have started walking normally. There is no issue in weight bearing but when I pick my operated leg and bend it to move forward there is locking at front and sometimes it causes pain also. This happens too often to ignore. I am really worried. Please provide any explaination for this.
