The Oxford Domed Lateral Partial Knee Replacement (ODLPKR) was designed specifically for the lateral compartment in response to the unacceptable dislocation rate seen with the Oxford Partial Knee. This paper presents the up to 10-year follow-up of an independent, single surgeon series using this implant. The aim of this study is to assess the medium term outcome of the ODLPKR. The primary outcome measures were 13 revision surgery, re-operation and functional outcome.


Sixty-four knees in 58 patients were performed between 2005 and 2009. Patients were interviewed by telephone to determine whether further surgery had been conducted on their knee and to complete an Oxford Knee Score (OKS) questionnaire.


The status of 61 knees was confirmed with a median follow-up period of 84 months. One patient sustained two bearing dislocations ultimately requiring an elective bearing exchange. Two knees underwent revision to TKR and five other patients reported further operations. Median OKS was 26 (range nine to 36) pre-operatively and 42 (10–48) at final follow-up.


The ODLPKR offers an effective and safe treatment for lateral compartment osteoarthritis. Bearing dislocation does not appear to be a significant issue with this implant and implant retention is similar to that achieved by medial unicompartmental knee replacements in the medium term.
