Osteoarthritis??

So i initially had a really bad knee injury two years ago (like even fractured my leg) and was walking in six days cause i had a huge case of college fomo. I waited three months to get surgery, so this December i’ll be 2 years post op. I am going to a new ortho, as i still have kneecap instability. While my surgeon repaired my acl, patellar tendon, all, and a partial lateral menisectomy, he was going to do mpfl reconstruction but never ended up doing so. Now, i went in for an xray ordered by my primary care until i get to ortho—i ended up with osteoarthritis????? I heard it’s normal like a decade after for like 1/2 surgery patients, and 1/3 5 years later, BUT NOT EVEN 2 YEARS?!?!?!?!? Really sucks 😞 going to ortho to see what they can do
