Brief summary

The aims of this study is to compare the results between patients without severe patellofemoral arthritis and patients with severe patellofemoral arthritis after mobile bearing UKA. The investigators prospective compute the results including anterior knee pain, knee society score, pain score, functional score, range of motion, operative time, blood loss, and component alignment.

Detailed description

The patients were performed surgery. The Oxford UKA was applied for all patient.
