In HS. 6 months later I was playing tennis at about half speed with a huge brace. Got demoted from #1 singles to mixed doubles. The following fall, 1 year post injury, I was playing JUCO singles and I would say I was 90%. The following year I played again and would say I was 95%. that's as far as I got. I could play at a high level, for me, we won our region my soph yr and I won my singles region. The reason I say 95% is I never got my full range of motion back, even today - 14 years later. I would say I was in good enough shape to play effectively after about 8 months. Keep in mind this was tennis and I was 17/18 years old. My physical therapist said I was the quickest recovery he had seen for this type of injury, and he treated USMs athletics for years. The thing that really killed me with this injury is that I had to keep my leg immobilized for 6 weeks post surgery bc I had no ligaments that weren't damaged. Typically, your leg is being moved by a machine before you wake up from surgery with one torn ligament. With mine being in a cast for 6 weeks, everything froze in place and scarred over. Before I could even begin true therapy, I had to work for another month to break apart all of the scars. By that time, the ligaments got all shrunk up from inactivity. That, added to the fact that the dr put them in extra tight to begin with (to ensure everything held together through recovery) is why I never got full range back. It's impossible to do with my scenario. I cannot begin to describe the pain this caused me for 5 solid months. Now, I don't know if this applies to someone with 2 torn ligaments or how they have advanced things medically in 14 years. But this all requires a huge amount of effort and desire to overcome...total dedication. From my experience, if his recovery is similar, I am not surprised to see 8/9 months projected for recovery. I expect it to be closer to a year or 15 months since he is playing in the NFL as opposed to playing JUCO tennis.
