Yeah when I tore the ACL in 2008, I had a partial PCL and meniscus tear. Only the ACL was fully replaced, the others were trimmed . They took part of my patella tendon and used it as my ACL donor, then in dec of 2012, I sprained the patellar tendon. And then hyper extended in the following month at which time there was a tiny tear that the doc said didn't warrant surgery.
