I had ACL recostruction on my left knee 17 days ago using a hamstring graft. Everything has gone well and I was able to achieve 110 degrees of flexion at my 2 week post-op appt, but then 2 days ago I was at a much needed trip to the coast and I was moving from the dock and stepping onto a boat (ofcourse with assistance), when I felt pain in my affected knee. I was wearing my ACL brace and did not hear a pop (which I didnt hear with my initial tear). I didnt collapse, just felt a pain similar to the pain I have felt behind my knee cap, but a little worse. After I calmed down, I tried to bend my knee and I could bend it further than I could before. I'm extremely sad/paranoid/worried that I retore my graft. I contacted a doctor and he said that there would have to be significant trama to tear it (running, cutting, jumping etc.) but I'm still worried just because a have a larger ROM know. I haven't had instability, but I haven't really tested it because I'm still wearing my brace and using one crutch. Has this happened to anyone else? Could my graft be torn?
