Thanks for your account.

Indeed, after a sporting injury (think meniscus tear, acl injury etc) you have a 50% chance of developing OA within ten years.

Its a sobering fact.

Its worse for females:


Over the past two decades there has been an alarming increase in the rate of ACL injuries in young females in sports that involve cutting, jumping and pivoting. Adolescent and mature females in these sports have ACL injuries at a two- to eight-fold greater rate than males participating in the same sports. This, along with a ten-fold increase in the number of women participating in sports since the inception of Title IX, has resulted in a dramatic increase in ACL injuries in females in the US.

...and they further stated...


The risk of knee OA from knee joint injury is high; approximately 50% of individuals with an ACL or meniscus tear develop knee OA .


Another group of researchers made this conclusion:



In young adults, knee injury increases the risk of future diagnosed knee OA about six fold with highest risks found after cruciate ligament injury, meniscal tear and intra-articular fracture.
