We describe postoperative functional outcome and accuracy of implant position in 38 cases after unicompartmental knee arthroplasty with the Oxford knee prosthesis with a standard open approach compared with 30 cases with a minimally invasive approach. Patients with the minimally invasive approach had significantly better functional results, with an average Hospital for Special Surgery scores of 92 (range, 81-98) compared with 78 (range, 24-99). Range of motion 1 year postoperatively was better in the minimally invasive group (113 degrees vs 107 degrees ), but the results were not statistically significant. The number of patients with extension lag was significantly higher after the open approach. The minimal invasive approach had no negative effect on positioning of the prosthesis. In our opinion, minimally invasive implantation is the method of choice for the treatment of anteromedial osteoarthritis by unicompartmental knee arthroplasty.
我们描述了采用标准开放入路的牛津膝关节假体进行单髁膝关节置换术后38例患者的术后功能结果及植入物位置准确性，并与30例采用微创入路的患者进行了比较。采用微创入路的患者功能结果明显更好，特殊外科医院平均评分为92分（范围81 - 98分），而开放入路组为78分（范围24 - 99分）。术后1年微创组的活动范围更好（113度对107度），但结果无统计学意义。开放入路后伸直滞后的患者数量明显更多。微创入路对假体定位没有负面影响。我们认为，微创植入是单髁膝关节置换治疗前内侧骨关节炎的首选方法。
