Knee osetotomy

[cutter21]

Has anyone had a knee osteotomy? orthoinfo.aaos.org/topic.cfm?topic=A00591

Looking for experiences/ results. I've had 4 surgeries on my right knee and this is the next step according to my surgeon. I have a large arthritic defect behind my knee cap, my doc will implant cadaver cartilage into the defect and then do the osteotomy to realign my joint. I've gone for 2 other opinions and have gotten the same answer.
