The subvastus approach for total knee replacement was compared with the standard medial parapatellar approach in terms of postoperative knee scores and quadriceps strength. Two groups of patients with similar characteristics were formed: the first group consisted of 12 knees of 9 patients who were implanted via the medial parapatellar approach, and for the second group the subvastus approach was used in 10 knees of 10 patients. The groups' knee scores and quadriceps strength were compared preoperatively and postoperatively at week 6, months 3 and 6. The knee scores improved similarly in both groups, but the change was more pronounced in the subvastus group. Quadriceps strength was greater in the subvastus group at postoperative week 6, but there was no significant difference between the groups in months 3 and 6. It was concluded that although the subvastus approach offers greater quadriceps strength in the early postoperative period, it has no significant advantage in this aspect over the medial parapatellar approach.
在术后膝关节评分和股四头肌力量方面，将全膝关节置换的股直肌下入路与标准内侧髌旁入路进行了比较。形成了两组特征相似的患者：第一组由9例患者的12个膝关节组成，这些膝关节通过内侧髌旁入路植入，第二组对10例患者的10个膝关节采用股直肌下入路。在术前以及术后第6周、3个月和6个月比较两组的膝关节评分和股四头肌力量。两组的膝关节评分均有相似改善，但在股直肌下组变化更为明显。术后第6周股直肌下组的股四头肌力量更大，但在3个月和6个月时两组之间无显著差异。得出的结论是，尽管股直肌下入路在术后早期提供了更大的股四头肌力量，但在这方面它与内侧髌旁入路相比没有显著优势。
