Windswept deformity is a condition of the lower limbs with a valgus knee on one side and a varus knee on the other. We present a case series of bilateral unicompartmental knee arthroplasty (UKA) for windswept knee osteoarthritis (WSKO).
We analysed the outcomes of 26 knees of 13 consecutive patients with WSKO treated with bilateral UKA. The mean age was 73.0 years and the mean follow up period was 2.6 years. Pre- and postoperative Oxford Knee Score (OKS) and Japanese Orthopaedic Association (JOA) score, radiological measurements and postoperative complications were evaluated. No knees required revision for either infection or loosening.
The mean preoperative OKS was 25.3 ± 9.7, which increased to 34.9 ± 5.8 at the latest follow up. The mean preoperative JOA scores for the varus and the valgus sides were 64.6 ± 12.5 and 66.9 ± 14.1, which increased to 85.0 ± 11.3 and 84.6 ± 11.2, respectively, after operation.
Our results show that good short-term clinical results can be achieved by bilateral UKA in cases of WSKO. Bilateral UKA may be an effective treatment for WSKO if indications are met.
迎风膝畸形是一种下肢疾病，一侧膝关节外翻，另一侧膝关节内翻。我们报告了一组双侧单髁膝关节置换术（UKA）治疗迎风膝骨关节炎（WSKO）的病例系列。
我们分析了 13 例连续患者的 26 膝 WSKO 接受双侧 UKA 治疗的结果。平均年龄为 73.0 岁，平均随访时间为 2.6 年。评估了术前和术后牛津膝关节评分（OKS）和日本矫形协会评分（JOA）、影像学测量和术后并发症。没有因感染或松动而需要翻修的膝关节。
平均术前 OKS 为 25.3±9.7，随访时增至 34.9±5.8。术前内翻和外翻侧的 JOA 评分分别为 64.6±12.5 和 66.9±14.1，术后分别增至 85.0±11.3 和 84.6±11.2。
我们的结果表明，双侧 UKA 治疗 WSKO 可获得良好的短期临床效果。如果符合适应证，双侧 UKA 可能是治疗 WSKO 的有效方法。
