The purpose of this study was to determine whether direct arthroscopic control of femoral buttons can prevent improper deployment and soft tissue interposition in anterior cruciate ligament (ACL) reconstruction.
A retrospective analysis of prospectively collected data from the SANTI study group database was performed. All patients who underwent ACL reconstruction using suspensive femoral fixation between 01/01/2017 and 31/12/2019 were included. Patient assessment included demographics, sports metrics, reoperations performed and femoral button-related specific complications such as iliotibial band (ITB) irritation and/or septic arthritis. Proper deployment of the button and soft tissue interposition were assessed on postoperative radiographs.
A total of 307 patients underwent ACL reconstruction using adjustable femoral button fixation and were analyzed after a mean follow-up of 35.2 ± 11.0 months (14.3-50.2). The mean age was 39.5 ± 10.9-years old (range 13.3-70.6). Postoperative radiographs showed a correctly deployed femoral button without soft tissue interposition for all patients. No septic arthritis was reported. Nine patients (2.9%) suffered from lateral pain related to ITB irritation due to the button. Five of them had their symptoms resolve during rehabilitation. Ultrasound-guided corticosteroid infiltration was necessary for four patients after an average delay of 14.5 ± 4.8 months (11.7-21.7). Three patients were then symptom-free, but one required surgical removal of the implant 27.5 months after the surgery. Regarding unrelated femoral button complications, 15 patients (4.9%) underwent secondary arthroscopic procedures, including meniscectomy (1.6%), surgery for cyclops syndrome (2.6%) and revision ACLR (0.7%).
Arthroscopic confirmation of femoral button deployment prevents soft tissue interposition without specific complications.

本研究旨在确定直接关节镜控制股骨纽扣是否可以防止前交叉韧带（ACL）重建中纽扣不当部署和软组织嵌顿。
对 SANTI 研究组数据库中前瞻性收集的数据进行回顾性分析。纳入 2017 年 1 月 1 日至 2019 年 12 月 31 日期间使用悬吊式股骨固定进行 ACL 重建的所有患者。患者评估包括人口统计学、运动学指标、再次手术以及与股骨纽扣相关的特定并发症，如髂胫束（ITB）刺激和/或化脓性关节炎。术后 X 线片评估纽扣的正确部署和软组织嵌顿情况。
共有 307 例患者接受了可调式股骨纽扣固定的 ACL 重建，平均随访 35.2±11.0 个月（14.3-50.2）后进行分析。平均年龄为 39.5±10.9 岁（范围 13.3-70.6）。所有患者术后 X 线片均显示股骨纽扣正确部署，无软组织嵌顿。无化脓性关节炎报告。9 例（2.9%）患者因纽扣引起 ITB 刺激出现外侧疼痛。其中 5 例在康复过程中症状缓解。4 例患者平均延迟 14.5±4.8 个月（11.7-21.7）后行超声引导下皮质类固醇浸润治疗。3 例患者症状缓解，但 1 例患者在手术后 27.5 个月需要手术取出植入物。关于无关的股骨纽扣并发症，15 例（4.9%）患者接受了二次关节镜手术，包括半月板切除术（1.6%）、单侧髁间棘切除术（2.6%）和 ACLR 翻修术（0.7%）。
关节镜确认股骨纽扣的部署可防止软组织嵌顿，且无特定并发症。
