PURPOSE Clinical outcomes between reattachment of the superior peroneal retinaculum (SPR) and the bone block procedure were compared in this study to elucidate which procedure was safer and more effective. METHODS From 2012 to 2016, 25 patients with recurrent peroneal tendon dislocation underwent the bone block procedure (group A), and another 22 patients underwent reattachment of the SPR (group B). American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Ankle Activity Score (AAS), time to return to sports activity, rate of return to sports level, range of motion (ROM) of the ankle, rate of recurrence, and overall patient satisfaction were collected to evaluate outcomes between the two groups. RESULTS In group A, 24 patients followed up at a mean period of 42.5 ± 16.7 months. The mean postoperative AOFAS score was 92.9 ± 3.9. The median time to return to sports activity was 6.0 months (IQR 4.3-6.0 months) with 19 patients (79.2%) returning to their previous sports level. Two patients experienced recurrent dislocation, and 22 patients (91.7%) were satisfied with the procedure. In group B, 20 patients followed up at a mean period of 35.8 ± 15.3 months. The mean postoperative AOFAS score was 95.0 ± 4.2. The median time to return to sports activity was 5.0 months (IQR 4.0-5.0 months) with 18 patients (90.0%) returning to their previous sports level. No recurrence was reported, and 18 patients (90.0%) were satisfied with the procedure. The time to return to sports activity in group B was significantly shorter than that in group A. There was no significant difference in complications or clinical outcomes between the two procedures. CONCLUSION Both procedures offered satisfactory results for recurrent peroneal tendon dislocation with low rates of recurrence and complications. However, the time to return to sports activity after the reattachment of the SPR was shorter than that after the bone block procedure. LEVEL OF EVIDENCE Retrospective Comparative Study, Level III.

腓骨上视网膜网膜再植术与骨块阻滞术治疗复发性腓骨肌腱脱位：两种安全有效的技术。

目的在本研究中比较了腓骨上视网膜（SPR）复位与骨阻滞手术之间的临床结局，以阐明哪种手术更安全，更有效。方法2012年至2016年，对25例复发性腓骨腱脱位患者进行了骨阻滞手术（A组），另外22例患者进行了SPR复位（B组）。美国骨科足踝协会（AOFAS）踝后足评分，踝关节活动评分（AAS），运动返回时间，运动水平返回率，踝关节运动范围（ROM），复发率以及收集患者的总体满意度以评估两组之间的结果。结果在A组中，有24例患者得到了随访，平均随访时间为42.5±16.7个月。术后AOFAS评分平均为92.9±3.9。恢复运动的中位时间为6.0个月（IQR为4.3-6.0个月），其中19位患者（79.2％）恢复了以前的运动水平。2例复发性脱位，其中22例（91.7％）对手术满意。B组中有20例患者接受了随访，平均时间为35.8±15.3个月。术后平均AOFAS评分为95.0±4.2。恢复运动的中位时间为5.0个月（IQR为4.0-5.0个月），其中18位患者（90.0％）恢复了以前的运动水平。没有复发的报道，并且18例患者（90.0％）对该手术感到满意。B组恢复运动的时间明显短于A组。两种手术在并发症或临床结局方面无显着差异。结论两种方法均能为复发​​性腓骨腱脱位提供满意的结果，复发率和并发症发生率低。但是，在重新安装SPR后，恢复运动的时间比在骨阻滞手术后恢复运动的时间短。证据级别回顾性比较研究，III级。
