The aim of this study is to prove the influence of the arthroscopic lateral release on functional recovery in adolescents with recurrent lateral dislocation of patella.
From 2006 to 2009, arthroscopic release of the lateral retinaculum was done on 27 adolescent patients (24 women, 3 men) and 33 knees (in 6 patients on both knees). All of them were active in different sports. The severity of patellar subluxation and dislocation was analysed on X-ray; the Q angle, congruence angle, sulcus angle, patellofemoral angle and height ratio were measured. Functional scores (Lysholm, Kujala, Tegner) were measured preoperatively and postoperatively. The average duration of clinical and X-ray follow-up was 4.5 years (range 3-6 years).
The mean age of the patients was 14.56 years (range 11-18 years). There was an average of 4.16 dislocations (range 2-28 dislocations) before surgery. The mean Lysholm score improved from 64 to 95 (p = 0.0002), and the mean Kujala score improved from 66 to 94 (p < 0.0001). Congruence angle and lateral patellofemoral angle improved but without any significant differences.
Arthroscopic lateral release successfully treats recurrent patellar dislocations in adolescents, influences functional recovery and improves knee function.
本研究旨在证明关节镜下外侧支持带松解术对复发性髌骨外侧脱位青少年患者功能恢复的影响。
2006 年至 2009 年，对 27 例（24 例女性，3 例男性）33 膝（6 例双膝）青少年患者进行关节镜下外侧支持带松解术。所有患者均积极参加不同的运动。X 线分析髌骨半脱位和脱位的严重程度；测量 Q 角、吻合角、沟角、髌股角和高度比。术前和术后测量功能评分（Lysholm、Kujala、Tegner）。临床和 X 线随访的平均时间为 4.5 年（范围 3-6 年）。
患者平均年龄为 14.56 岁（范围 11-18 岁）。术前平均脱位 4.16 次（范围 2-28 次）。Lysholm 评分平均从 64 分提高到 95 分（p=0.0002），Kujala 评分平均从 66 分提高到 94 分（p<0.0001）。吻合角和外侧髌股角改善，但无显著差异。
关节镜下外侧支持带松解术成功治疗青少年复发性髌骨脱位，影响功能恢复，改善膝关节功能。
