[|Human|] Hi! I had ACL reconstruction using a hamstring graft about a year ago. I was released from physical therapy and have been playing sports again for about 6 months now. But I recently noticed a large, hard, non movable lump below the scar on my surgery knee. It occasionally hurts, esspecially after physical activity. I know it s not scar tissue. But I m very unsure of what it could be. If you know anything that could help me, please let me know! Thank you!
[|AI|]  Hi, thanks for the brief history of you. As you mentioned the scar, ACL reconstruction, Physical therapy and your physical activity which lead to pain. What I can feel is it might not be a lump but something else. Now as you said it is below the scar, So which scar it is, the place from where the graft was taken or the place where the graft is placed. Also, is the lump in the back of the knee? If it is behind the knee it can be popliteal cyst. Until it is checked it cannot be predicted. Because post surgery needs to examine. Even an incisional hernia can be a possibility but only after a thorough examination it can be diagnosed. Also, it is not a matter of worry. Because conservative management will be always possible. With the grace of god I wish you a good health
