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 84months. 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.
牛津穹顶外侧部分膝关节置换术（ODLPKR）是专门为外侧间室设计的，以应对牛津部分膝关节置换术中出现的不可接受的脱位率。本文介绍了使用该植入物的一个独立的、由单一外科医生进行的系列手术长达10年的随访情况。本研究的目的是评估ODLPKR的中期疗效。主要结局指标为翻修手术、再次手术和功能结局。
2005年至2009年间对58例患者的64个膝关节进行了手术。通过电话采访患者，以确定其膝关节是否进行了进一步手术，并完成牛津膝关节评分（OKS）问卷。
61个膝关节的情况得到确认，中位随访期为84个月。1例患者发生了两次假体脱位，最终需要择期更换假体。2个膝关节翻修为全膝关节置换术，另外5例患者报告进行了进一步手术。术前OKS中位数为26（范围9至36），末次随访时为42（10至48）。
ODLPKR为外侧间室骨关节炎提供了一种有效且安全的治疗方法。对于这种植入物，假体脱位似乎不是一个重大问题，并且在中期，植入物的保留情况与内侧单髁膝关节置换术相似。
