A few weeks ago I tore my ACL (not skydiving), I actually jumped with my injured knee before I saw the doc and got a diagnosis (it didn't feel that bad at the time). Since then I've jumped and my knee is definitely not fully recovered (nor will it ever without surgery), and the stresses we normally take for granted on landing seem magnified with my dodgy knee albeit with a slightly briused femur at the time. So I'm considering the possibility of surgery, a fairly serious business for an ACL repair with a long recovery. My question is does anyone else here jump with a torn ligament? Do you wear a brace? Yea I know there are folks who jump in worse shape, my main concern is really about additional injury to a weakened knee (long term prospects for arthritis)and whether to elect for the surgery.
