Randomized trial shows unicompartmental prosthetic replacement improves function in knee arthritis, suggesting better outcomes.

Unicompartmental prosthetic replacement resulted in better overall outcomes than high tibial osteotomy.
In the osteotomy group, 30% had poor results; in the prosthetic group, only 4.5% reported poor outcomes.
This assessment involved 40 patients reviewed over a mean follow-up of 24 months in one group and 41 months in another.
Proper patient selection and precise component placement may enhance treatment effectiveness.

Karpman et al. (1982) studied this question.
