Reconstructed ACL Using Hamstring - Have I Damaged It?

Hi All

About nine days ago I had an ACL Reconstruction using hamstring graft and I understand the surgery went well.

However, during the middle of the night (when I did not have the brace on) I got up to go to the toilet and I did feel a bit of a brief sharp pain when I stepped off the operated leg, although by no means was it severe. There was no slip or fall, more like a give way episode when I stepped on and off the operated leg - I think it went to full extension and it didn't like this.

Would this have likely to have done permanent damage to the reconstructed ACL?

Just to add to above, I think it was a give way episode due to lack of muscle control following surgery. I think it is discussed here:
