Brief summary

The objective of this prospective study is to determine (1) the time course of patient-relevant functional outcome evaluated by the Knee injury and Osteoarthritis Outcome Score (KOOS) and (2) the time course of range of motion (ROM) the first six years following Oxford Medial Unicondylar Knee prosthesis. Improvement of patient self-reported pain and daily function during the study period, are of particular interest.
