This study was performed to determine whether differences existed between primary knee replacement performed through a standard medial parapatellar approach, and those performed through a minimally invasive mini-mid vastus approach. It was a prospective study compared with a retrospective evaluation of a matched cohort. In this study, the Genesis(tm) II and its MIS instrumentation were used. Patients with the mini-mid vastus MIS incision (MMV MIS) required less pain medication post-operatively, regained their flexion more rapidly, and attained their functional milestones at an earlier point than those with the traditional median parapatellar long incision. Despite the smaller incision, component placement was radiographically excellent in all cases. Optimal performance of the surgery required the use of special instrumentation, modified so as to be used in smaller incisions.
本研究旨在确定经标准内侧髌旁入路进行的初次膝关节置换与经微创小中间股四头肌入路进行的初次膝关节置换之间是否存在差异。这是一项前瞻性研究，并与匹配队列的回顾性评估进行比较。在本研究中，使用了Genesis(tm) II及其微创器械。与传统内侧髌旁长切口患者相比，采用小中间股四头肌微创切口（MMV MIS）的患者术后所需止痛药物更少，更快恢复屈膝功能，且在更早时间达到功能里程碑。尽管切口较小，但所有病例的假体植入在影像学上均表现出色。手术的最佳效果需要使用经过改良以便在较小切口中使用的特殊器械。
