Trochleoplasty is a recognized surgical technique to address severe trochlear dysplasia. The clinical and radiological outcomes of trochleoplasty surgery in trochlear dysplasia have been well reported. There is a paucity in literature regarding the correlation between trochleoplasty and quality of life (QoL). The aim of this study is to measure the improvement in QoL, in patients with severe trochlear dysplasia and recurrent patellar instability following trochleoplasty.
Between 2013 and 2019, 51 trochleoplasty cases were performed in 48 patients. They were identified from our prospectively kept database. All operations were performed by a fellowship trained consultant sports knee surgeon. Functional outcomes and QoL scores were assessed using Kujala, IKDC and EQ-5D index. Objective outcomes were obtained following each patient's latest follow-up assessment.
The mean age at operation was 22y (SD ± 4.7, range 14-37y) and the mean follow-up period was 21.6 months (SD ± 15.2, range 12-60 months). The mean Kujala score improved from 58.1 (SD 14.9) to 77.9 (SD 17.3) at latest follow-up (p < 0.001). The mean IKDC score improved from 40.5 (SD 14.2) to 69.5 (SD 22.8) at latest follow up (p < 0.001). The mean EQ-5D index also improved from 0.593 (SD 0.257) to 0.824 (SD 0.189) at latest follow-up (p = 0.003). A higher Body Mass Index (BMI; >30 kg/m) was associated with inferior outcomes.
Trochleoplasty is an effective surgical technique which improves the QoL in patients suffering from patellar instability secondary to severe trochlear dysplasia. BMI can be used to predict post-operative outcomes.
滑车成形术是一种公认的治疗严重滑车发育不良的手术技术。滑车成形术治疗滑车发育不良的临床和放射学结果已有很好的报道。然而，关于滑车成形术与生活质量（QoL）之间的相关性的文献却很少。本研究的目的是测量严重滑车发育不良和复发性髌骨不稳定患者行滑车成形术后 QoL 的改善情况。
2013 年至 2019 年，48 例患者的 51 例滑车成形术病例被纳入研究，所有手术均由一位经过专业培训的关节镜运动膝关节外科医生完成。采用 Kujala、IKDC 和 EQ-5D 指数评估功能结果和 QoL 评分。根据每位患者的最新随访评估获得客观结果。
手术时的平均年龄为 22 岁（SD ± 4.7，范围 14-37 岁），平均随访时间为 21.6 个月（SD ± 15.2，范围 12-60 个月）。Kujala 评分从术前的 58.1（SD 14.9）提高到末次随访时的 77.9（SD 17.3）（p < 0.001）。IKDC 评分从术前的 40.5（SD 14.2）提高到末次随访时的 69.5（SD 22.8）（p < 0.001）。EQ-5D 指数也从术前的 0.593（SD 0.257）提高到末次随访时的 0.824（SD 0.189）（p = 0.003）。较高的体重指数（BMI；>30 kg/m）与较差的结果相关。
滑车成形术是一种有效的手术技术，可改善因严重滑车发育不良导致髌骨不稳定的患者的生活质量。BMI 可用于预测术后结果。
