Knee Ostechondral Defect

Hi,

I had an MRI scan from an injury i did on 24th December 2020 with the results coming back on the 15th July - They showed i had Bone bruising on the lateral femoral condyle as well as having a 1cm osteochondral defect at the lateral tibial plateau. This is on the same knee i had a tibial transfer 4 years ago.

I have just received my first face to face appointment on this and noticed its with a physio - Im just wondering what use that would be as from everything ive read it seems surgery is the only way to correct the defect.

Im hoping someone can explain this to me.

Thanks in advance
