The short-term clinical and radiographic outcomes of two different valgus unloading braces were compared in patients with medial knee osteoarthritis (OA) and a varus leg alignment. A RCT was performed in 100 patients (50 Bledsoe Thruster brace, 50 SofTec OA brace) with symptomatic medial knee OA and a varus leg alignment. Outcomes were the visual analogue scale pain and satisfaction, Dutch Western Ontario and McMaster Universities Osteoarthritis Index, SF-12, 6-Minutes Walking Test, hip-knee-ankle alignment, analgesic use, complications and compliance after a follow-up of 2 and 12 weeks. The clinical and radiographic outcomes were not significant different between both groups. Almost all clinical outcomes improved in both groups at follow-up compared to baseline. 24% of the patients discontinued using the brace. No significant differences in clinical and radiographic outcomes were found between both groups after 2 and 12 weeks follow-up. Both braces were effective in the treatment of varus medial knee OA. Complications and compliance remains a problem.
对两种不同的外翻卸载支具在膝内侧骨关节炎（OA）且下肢呈内翻畸形患者中的短期临床和影像学结果进行了比较。对100例有症状的膝内侧OA且下肢呈内翻畸形的患者进行了一项随机对照试验（RCT）（50例使用布莱索推进器支具，50例使用索泰克OA支具）。结果指标包括视觉模拟量表疼痛评分和满意度、荷兰西安大略和麦克马斯特大学骨关节炎指数、SF-12、6分钟步行试验、髋-膝-踝对线、镇痛药使用情况、并发症以及随访2周和12周后的依从性。两组之间的临床和影像学结果无显著差异。与基线相比，两组在随访时几乎所有临床结果均有改善。24%的患者停止使用支具。随访2周和12周后，两组之间在临床和影像学结果方面未发现显著差异。两种支具在治疗膝内翻内侧OA方面均有效。并发症和依从性仍然是个问题。
