Analysis of first forty Oxford medial unicompartmental knee replacement from a small district hospital in UK

We present a prospective review of our first 40 consecutive Oxford unicompartmental knee replacements for anteromedial osteoarthritis from a small District General Hospital performing an average of 8 operations each year. At an average follow-up of 7.5 years (6–10 years), no revisions were undertaken with a significant improvement in the Oxford and American Knee Score at review. Our study confirms the good results reported from other centres when strict selection criteria and surgical techniques are met. It does not support the observation that less number of these procedures performed each year correlate with a poorer outcome.
