Well, it's kinda embarassing on how I tore it. All I was doing was sitting on the ground with my left leg bent, my foot in my crotch area and my right let was straight out in front of me and I was stretching before my PT test that I have to take in the military. I was done stretching, went to get up and felt my knee pop, knew what it probably meant. Sometimes when it pops, I can slowly straighten it out and get it to pop again, and fix the problem. But this time I couldn't and the MRI confirmed that the lateral meniscus tore and flipped posterior to anterior. The knee suregery I had in 2001 they repaired, the knee surgery in 2007 they removed the torn part. I'm just wondering how much more meniscus can they take out? The most frustrating part of this whole thing is I was just starting to feel pretty confident with my knee. My husband and I have probably done about 60-100 miles of hiking and backcountry camping and I've put about 400 miles on my bike this summer, lost 25 lbs, and 6% body fat. I had done all of that without hardly and pain. I almost wish they would just give me knee replacement surgery because those are supposed to last around 10-20 years. I would be pretty happy with not having to have another surgery for 10-20 years. But I also do know that knee replacement surgery is alot more evasive than just a meniscus repair. But they don't like to give 30 yrs olds knee replacement surgery. So we'll see what happens but I'm getting fed up with the knee surgeries and pain. My husband and I were hoping to go to Arizona next year and do some real hiking but no so sure now!!
