3 years ago. It's full of arthritis and hurts all the time. The 2nd meniscus surgery helped because the knee was locking up but didn't help much with pain. Because of the arthritis it took a good 4-6 months before I felt confident being active again.
Doc says I'll need a replacement at some point but I want to hold out as long as I can. I'll forever curse BYU intermural flag football for ruining my knee.
