Background Although the minimal invasiveness of arthroscopic ankle lateral ligament repair (ALLR) means that an early return to sporting activities can be anticipated, studies have described postoperative cast immobilization and the avoidance of weightbearing for a certain period. Accelerated rehabilitation may be helpful for an early return to sport. Purpose To investigate clinical outcomes of ALLR and accelerated rehabilitation with a minimum duration of postoperative ankle immobilization and proactive early weightbearing. Study Design Case series; Level of evidence, 4. Methods This study investigated 23 ankles of 22 patients (11 men, 11 women; mean age, 38.7 years) who underwent ALLR for chronic lateral ankle instability. Postoperative management included the avoidance of weightbearing until postoperative day 3, after which full weightbearing walking with a brace was permitted. The objective was to return to competitive sport 8 weeks after surgery. The following were evaluated: pre- and postoperative instability and pain symptoms, ankle range of motion, anterior drawer distance on stress radiograph, anterior translation measured with a capacitance-type strain sensor, the Ankle-Hindfoot Scale from the Japanese Society for Surgery of the Foot, and the SAFE-Q (Self-Administered Foot Evaluation Questionnaire). Results Two male patients dropped out and were excluded from analysis. Postoperatively, instability and pain resolved or improved in all patients. There was no significant postoperative change in range of motion. There were significant pre- to postoperative improvements in talar tilt angle (from 12.2°-5.6°, P < .01), anterior drawer distance (8.2-4.4 mm, P < .01), and anterior translation (10.5-4.6 mm, P < .01) as well as the Ankle-Hindfoot Scale score (68.8-96.8, P < .01) and all subscales of the SAFE-Q (P ≤ .01 for all). Complete return to sport was achieved by 75% of the patients at 8 weeks postoperatively. Conclusion When accelerated rehabilitation with proactive weightbearing exercises was implemented from postoperative day 3 without ankle immobilization after ALLR, there were significant improvements in objective assessments of ankle stability and clinical scores, and as many as 75% of the patients were able to make a complete return to sport within 8 weeks.

加速康复对关节镜踝关节外侧韧带修复术后早期恢复运动的影响。

背景 虽然关节镜下踝关节外侧韧带修复术 (ALLR) 的微创性意味着可以预期早期恢复体育活动，但研究已经描述了术后石膏固定和在一定时期内避免负重。加速康复可能有助于尽早恢复运动。目的 研究 ALLR 和加速康复的临床结果，术后踝关节固定时间最短，主动早期负重。研究设计案例系列；证据级别，4。方法 本研究调查了因慢性外侧踝关节不稳而接受 ALLR 的 22 名患者（11 名男性，11 名女性；平均年龄，38.7 岁）的 23 名踝关节。术后管理包括避免负重直到术后第 3 天，之后，允许使用支架完全负重行走。目标是在手术后 8 周重返竞技运动。评估了以下内容：术前和术后的不稳定和疼痛症状、踝关节活动度、应力射线照片上的前抽屉距离、用电容型应变传感器测量的前平移、日本外科学会的踝-后足量表足部和 SAFE-Q（自我管理足部评估问卷）。结果两名男性患者退出并被排除在分析之外。术后，所有患者的不稳定性和疼痛均得到缓解或改善。术后活动范围无明显变化。距骨倾斜角（从 12.2°-5.6°，P < .01）、前抽屉距离（8.2-4. 4 mm，P < .01）和前移（10.5-4.6 mm，P < .01）以及踝-后足量表评分（68.8-96.8，P < .01）和 SAFE-Q 的所有分量表（所有 P ≤ .01）。术后 8 周，75% 的患者完全恢复运动。结论 ALLR 术后第 3 天开始实施主动负重加速康复训练，无需固定踝关节，踝关节稳定性和临床评分的客观评估有显着改善，多达 75% 的患者能够完全康复8周内运动。术后 8 周，75% 的患者完全恢复运动。结论 ALLR 术后第 3 天开始实施主动负重加速康复训练，无需固定踝关节，踝关节稳定性和临床评分的客观评估有显着改善，多达 75% 的患者能够完全康复8周内运动。术后 8 周，75% 的患者完全恢复运动。结论 ALLR 术后第 3 天开始实施主动负重加速康复训练，无需固定踝关节，踝关节稳定性和临床评分的客观评估有显着改善，多达 75% 的患者能够完全康复8周内运动。
