Background:Fresh osteochondral allograft (OCA) transplantation is a viable treatment option for osteochondral defects of the talus. However, sufficient data are not available on patients’ participation in sports or recreational activities after the procedure.Purpose:To assess whether patients undergoing OCA transplantation of the talus participated in sports or recreational activities postoperatively.Study Design:Case series; level of evidence, 4.Methods:A total of 36 ankles in 34 patients underwent OCA transplantation of the talus. At a mean follow-up of 9.2 years, information on participation in sports or recreational activities pre- and postoperatively was obtained, as well as postoperative pain, function, and satisfaction.Results:The mean age at the time of surgery was 36.1 years (range, 20.5-57.7 years), and 50% of patients were men. The mean graft size was 3.6 cm2 (range, 1-7.2 cm2) or 41.1% of the talar dome. Before the injury, 63.9% of patients (23/36 ankles) reported being highly competitive athletes or well trained and frequently sporting; 36.1% of patients (13/36 ankles) reported sometimes sporting or were nonsporting. Also, 66.7% of patients (24/36 ankles) were able to participate in sports or recreational activities after OCA transplantation and 50% (18/36 ankles) were still participating in sports or recreational activities at the latest follow-up. In a subset of well-trained or highly competitive athletes, 73.9% (17/23 ankles) were able to return to sports or recreational activities at any point after OCA transplantation, and 65.2% (15/23 ankles) were still participating at the latest follow-up. Further surgery occurred in 16.7% of patients (6/36 ankles). Graft survivorship was 94.3% at 5 years and 85.3% at 10 years. There was a significant improvement in the mean Olerud-Molander Ankle Scores, and the mean Foot and Ankle Ability Measure scores were high postoperatively. Moreover, 79.4% of patients (27/34 ankles) were either satisfied or extremely satisfied with the allograft surgery.Conclusion:Fresh OCA transplantation is a reasonable surgical option for osteochondral defects of the talus for young, active patients who have failed previous operative management or have massive defects.

距骨同种异体骨软骨移植后参加体育或娱乐活动

背景：新鲜同种异体骨软骨移植（OCA）移植是距骨骨软骨缺损的可行治疗选择。然而，关于患者术后参加体育或娱乐活动的情况尚无足够的数据。目的：评估接受OCA距骨移植的患者术后是否参加体育或娱乐活动。研究设计：病例系列；证据级别4级。方法：34例患者36个踝关节接受OCA距骨移植。平均随访 9.2 年，获得有关术前和术后参与体育或娱乐活动以及术后疼痛、功能和满意度的信息。 结果：手术时的平均年龄为 36.1 岁（范围，20.5-57.7岁），50%的患者是男性。平均移植物尺寸为 3.6 厘米2（范围，1-7.2 厘米2) 或距骨穹顶的 41.1%。受伤前，63.9% 的患者（23/36 脚踝）表示自己是竞技性很强的运动员或训练有素且经常运动； 36.1% 的患者（13/36 脚踝）报告有时进行运动或不进行运动。此外，OCA移植后66.7%的患者（24/36脚踝）能够参加体育或娱乐活动，并且50%（18/36脚踝）在最近的随访时仍在参加体育或娱乐活动。在训练有素或竞争激烈的运动员中，73.9%（17/23 脚踝）能够在 OCA 移植后的任何时候恢复体育或娱乐活动，65.2%（15/23 脚踝）仍在参加比赛最新跟进。 16.7% 的患者（6/36 脚踝）进行了进一步手术。 5 年移植存活率为 94.3%，10 年存活率为 85.3%。术后平均 Olerud-Molander 踝关节评分有显着改善，足部和踝关节能力测量平均评分较高。此外，79.4%的患者（27/34踝关节）对同种异体移植手术感到满意或非常满意。 结论：对于既往手术治疗失败的年轻、活跃的距骨骨软骨缺损患者，新鲜 OCA 移植是一种合理的手术选择或有大量缺陷。
