Patellar dislocations in patients presenting with recurrent patellofemoral instability can damage the surrounding structures, limiting patient's participation to recreational activities and quality of life. This study evaluated frequency, location, and extent of associated injuries in patients with recurrent patellar dislocation.
This systematic review was conducted according to the PRISMA checklist. PubMed, Google scholar, Embase, and Web of Science databases were accessed in July 2021. All the published clinical studies reporting frequency, location, and extent of soft tissue lesions in patients with recurrent patellar dislocations were accessed.
Data from 9 articles (232 patients) were retrieved. The mean age of the included patients was 21.2 ± 5.6 years. 84.8% of patients suffering from recurrent patellar dislocations demonstrated patellar chondral defects: medial facet (34.9%), while patellar crest (34.8%) and lateral facet (17%). 27.8% of patients demonstrated trochlear chondral injuries.
Chondral defects of the medial facet and the crest of the patella are the most common in patients with recurrent patellofemoral instability.
在复发性髌股关节不稳定的患者中，髌骨脱位可损伤周围结构，限制患者参与娱乐活动和生活质量。本研究评估了复发性髌骨脱位患者伴发损伤的频率、位置和程度。
本系统评价按照 PRISMA 清单进行。于 2021 年 7 月检索 PubMed、Google Scholar、Embase 和 Web of Science 数据库。检索所有报道复发性髌骨脱位患者软组织损伤频率、位置和程度的已发表临床研究。
纳入 9 篇文献（232 例患者）。纳入患者的平均年龄为 21.2±5.6 岁。84.8%的复发性髌骨脱位患者存在髌骨软骨缺损：内侧关节面（34.9%），髌骨嵴（34.8%）和外侧关节面（17%）。27.8%的患者存在滑车软骨损伤。
复发性髌股关节不稳定患者中最常见的是内侧关节面和髌骨嵴的软骨缺损。
