There is a paucity of quality of life (QoL) assessments in studies evaluating patients treated for recurrent lateral patellar dislocation (LPD). The primary aim of this study was to investigate whether mental well-being is impaired in patients with chronic (recurrent) LPD and, if so, to assess whether the mental health-related QoL dimension improves equivalently to the physical-related QoL dimension after successful surgical treatment. Thirty-eight patients with recurrent LPD over a mean course of the disease of 4.7 ± 3.9 years (1—18 years) prior to surgery were included. Generic health-related QoL (HRQoL) (Short Form 36; SF-36) and disease-specific QoL (Banff Patella Instability Instrument 2.0; BPII 2.0) were assessed preoperatively and after a mean follow-up of 3.5 ± 0.8 years (2 – 5 years) postoperatively. Untreated LPD significantly impacted the physical dimension of patients’ generic HRQoL and their disease-specific QoL. When compared to age-equivalent normative data sets, the mental HRQoL dimension was not reduced prior to operative treatment but increased during the follow-up period. Surgical treatment normalized the physical dimension of patients’ generic HRQoL and significantly improved their disease-specific QoL. However, BPII 2.0 values remained reduced, albeit patellae were successfully stabilized. The results of this study indicate that patients with recurrent LPD are generally in good mental health, although physical impairment is striking. Notwithstanding that surgery prevented further dislocations and normalized the generic HRQoL, the disease-specific QoL remained reduced as far as this can be interpreted without population-based data.

复发性髌骨脱位患者的心理和身体健康相关生活质量——一项通用和特定疾病的生活质量问卷评估

在评估接受复发性髌骨外侧脱位 (LPD) 治疗的患者的研究中，缺乏生活质量 (QoL) 评估。本研究的主要目的是调查慢性（复发性）LPD 患者的心理健康是否受损，如果是，则评估成功后心理健康相关 QoL 维度是否与身体相关 QoL 维度改善相当手术治疗。包括 38 名在手术前平均病程为 4.7 ± 3.9 年（1-18 年）的复发性 LPD 患者。在术前和平均随访 3.5 ± 0.8 年 (2 – 5 年）术后。未经治疗的 LPD 显着影响患者一般 HRQoL 的物理维度及其特定疾病的 QoL。与年龄相当的规范数据集相比，心理 HRQoL 维度在手术治疗前并未降低，但在随访期间有所增加。手术治疗使患者一般 HRQoL 的身体维度正常化，并显着改善了他们的疾病特异性 QoL。然而，尽管成功稳定了髌骨，BPII 2.0 值仍然降低。这项研究的结果表明，患有复发性 LPD 的患者通常心理健康状况良好，尽管身体损伤很严重。尽管手术防止了进一步的脱位并使通用 HRQoL 正常化，但只要没有基于人群的数据就可以解释，疾病特异性 QoL 仍然降低。第四级；回顾性案例系列。
