The results of minimally invasive techniques used for total knee replacement are controversial. Despite reported advantages such as faster recovery, there are some concerns regarding component positioning. We compared mini-midvastus versus medial parapatellar arthrotomy with respect to component position and functional results. We included 70 osteoarthritis total knee replacement patients in our study. Patients were randomised for the approach. We recorded Knee Society scores before and after the surgery and radiological component position. Patients were followed up to 12 weeks after the surgery. We found that the mini-midvastus approach was associated with better Knee Society scores six weeks after surgery; after 12 weeks the difference was not statistically significant. We found no difference related to the approach in radiological component position. The mini-midvastus approach is associated with faster recovery and reproduces the same accuracy in component positioning as the medial parapatellar approach.
用于全膝关节置换的微创技术的结果存在争议。尽管有报道称其具有恢复更快等优点，但对于假体组件的定位仍存在一些担忧。我们比较了小切口股中肌入路与髌旁内侧关节切开术在假体组件位置和功能结果方面的差异。我们的研究纳入了70例骨关节炎全膝关节置换患者。患者被随机分配手术入路。我们记录了手术前后的膝关节协会评分以及放射学上的假体组件位置。患者术后随访至12周。我们发现，小切口股中肌入路在术后六周时膝关节协会评分更高；12周后差异无统计学意义。我们发现两种入路在放射学假体组件位置方面没有差异。小切口股中肌入路与更快的恢复相关，并且在假体组件定位上与髌旁内侧入路具有相同的准确性。
