I've gone to one surgeon that thought a bilateral partial knee replacement would be best. This is on the medial side of both knees. I have varus deformity (bow-legs). While this surgeon is first rate with 200+ knee replacements a year, I wanted to alleviate any questions in my mind about partial/full. I just went to a second surgeon and he is also highly rated doing 200+ knee replacements a year. He said that he would NOT do a partial. His reason is that there is too much varus deformity and OA in the patella area. He thought the deformity was close to 20% but he never measured it. So I'm not sure how to resolve this conflict. The second surgeon also said I had OA in the patella region also. My preference is the PKR due to only removing the bad and keeping the good. Also the hope that the PKR knee will feel more natural. Both surgeons use MAKO robotics and Stryker prosthetic. The first surgeon was looking at a 6 month old xray. The second surgeon looked at xrays done that day. Another point is both will have a cat scan (because of the robotics). Will varus angulation and other issues (OA in another compartment) show up on the cat scan that will change the recommended solution from PKR to TKR?
