I did some research in this area a few years ago. Outcomes were very good. The only consideration for me would be- will I need further surgery down the rode and what would the outcomes be then (as a second surgery). There’s not enough data to support these as the partial knee replacements are still fairly new. While, this would be a consideration for me, I probably would still do it as there is a lot of of harm due to inflammation secondary to arthritis also.
