Thanks for your reply. 15% trimmed should not be that bad. How long ago did they reconstruct your ACL and how old were you at the time ? Did you get operated quickly ? I was operated 4 months after a basketball injury. My problem is that I have 3 meniscus tears (2 small one on the lateral side) and 1 in the medial side . All left in situ as apparently they are degenerative tears but I believe the 2 lateral tears were caused by keeping on playing basketball as I went to see a physio who mis diagnosed me because my knee was still stable.
