I have localised swelling in the back of the knee. I have been using RICE technique. The swelling is up to the inside of my leg by the groin also.

I can straighten my leg with little pain but bending it past 120 degrees hurts. I am on day 3 of my rehab after the op. I pulled my hamstring literally 4 hours after the op.

I believe the reason for this is i have been operating fully without a ACL for 2 years so i presume my hamstring has adapted to make up for this. Once a new ACL was fitted it will have stretched my Hamstring back and then obviously it has been too much for it. If that makes sense? Also hyperextension.

I panicked a but today and made an emergency visit to the physio. He confirmed that it looks like a hamstring tear/sprain.

I asked about the acl damage and he said because of the swelling it was difficult to tell but he said that the graft should be ok.

Thanks for you very detailed and impressive response. You got it completely right and that was without a visual.

You are obviously very good at your job.

My only concern is the liklyhood that it will have streched the ACL graft or damadged it but you said this is unlikly? Can you explain further?
