Management of posttraumatic knee stiffness (PTKS) is among the most difficult challenges in postoperative rehabilitation.
The purpose of this retrospective study was to present the outcomes of a procedure for PTKS. In this study, a less invasive procedure was introduced, which included intra-articular arthroscopic release, extra-articular mini-incision release and "multiple Z" lengthening of the knee extensor, as well as an early, aggressive rehabilitation protocol.
A series of patients aged from 29 to 60 years were treated with this procedure from April 2005 to May 2009, and the mean duration of follow-up was 13.5 months.
The range of motion increased significantly in all patients. Flexion improved from a mean of 51° preoperation to a mean of 100° at discharge, and the average extension loss improved from 10° to 3° (p < 0.000). The average knee score, according to the Hospital for Special Surgery system, improved from 62 points preoperatively to 77 points at discharge, and 91 points at final follow-up (p < 0.000). All the patients were satisfied with the final ROM gain.
创伤后膝关节僵硬（PTKS）的治疗是术后康复中最具挑战性的问题之一。
本回顾性研究旨在介绍一种治疗 PTKS 的方法。在本研究中，引入了一种微创治疗方法，包括关节内关节镜松解、关节外小切口松解和膝关节伸肌的“多个 Z”延长，以及早期积极的康复方案。
2005 年 4 月至 2009 年 5 月，一系列年龄在 29 至 60 岁之间的患者接受了该手术治疗，平均随访时间为 13.5 个月。
所有患者的关节活动度均显著增加。屈曲从术前平均 51°增加到出院时的平均 100°，平均伸展损失从 10°改善至 3°（p < 0.000）。根据特种外科医院（HSS）系统，膝关节评分从术前的 62 分提高到出院时的 77 分，最终随访时为 91 分（p < 0.000）。所有患者对最终的关节活动度增加均感到满意。
