OBJECTIVE
To compare the clinical and radiological outcomes of conventional medial and lateral approaches for total knee replacement in the valgus osteoarthritic knee.
METHODS
In this randomized controlled trial, 21 patients with valgus knee osteoarthritis were randomized to total knee replacement through medial or lateral approach. The primary outcome was radiographic patellar tilt. Secondary outcomes were visual analog scale of pain, postoperative levels of hemoglobin, and clinical aspect of the operative wound.
RESULTS
There were no differences between the groups regarding other clinical variables. Mean lateral tilt of the patella was 3.1 degrees (SD ± 5.3) in the lateral approach group and 18 degrees (SD ± 10.2) in the medial approach group ( = 0.02). There were no differences regarding the secondary outcomes.
CONCLUSION
Lateral approach provided better patellar tilt following total knee replacement in valgus osteoarthritic knee.
目的
比较外翻膝骨关节炎行全膝关节置换时传统内侧入路与外侧入路的临床及影像学结果。
方法
在这项随机对照试验中，21例外翻膝骨关节炎患者被随机分为通过内侧或外侧入路行全膝关节置换。主要结局为影像学上的髌骨倾斜度。次要结局包括疼痛视觉模拟量表、术后血红蛋白水平以及手术切口的临床情况。
结果
两组在其他临床变量方面无差异。外侧入路组髌骨平均外侧倾斜度为3.1度（标准差±5.3），内侧入路组为18度（标准差±10.2）（P = 0.02）。次要结局方面无差异。
结论
外翻膝骨关节炎行全膝关节置换时，外侧入路能提供更好的髌骨倾斜度。
