儿童与青少年习惯性髌骨脱位“三合一”术式中期随访显示功能改善且无复发：一项回顾性病例系列
简介
本研究回顾性纳入42例骨骼未成熟的习惯性髌骨脱位患儿（2017-2022年），接受改良“三合一”术式：广泛外侧松解、髌腱内侧半移位伴骨膜下固定、以及半腱肌自体移植物重建MPFL。平均随访52.1±9.2个月，无脱位复发或严重并发症，所有患者恢复全活动度且膝关节功能满意。功能评分较术前显著改善，但2例（4.8%）仍存在异常轨迹。临床意义：该改良术式在青少年中短…
英文摘要
PURPOSE: To introduce the 'three-in-one' surgical procedure, and to report its clinical outcomes. METHODS: This retrospective clinical study included 42 skeletally immature patients with habitual patellar dislocation who underwent a 'three-in-one' surgical procedure from 2017 to 2022. This procedure comprised an extensive lateral release, half medial transfer of patellar tendon with subperiosteal fixation, and reconstruction of the medial patellofemoral ligament with semitendinosus autograft. The clinical results were evaluated using preoperative and postoperative functional score and imaging. RESULTS: All patients returned for follow-up at a mean of 52.1 ± 9.2 months after surgery. There was no recurrence of dislocation or severe complications. All the patients have resumed full activities with satisfactory knee function. There was a statistically significant improvement in knee function scores. Abnormal tracking remained in two patients (4.8%). CONCLUSION: The modified 'three-in-one' surgical procedure is effective and safe in treating habitual dislocation in adolescents.
