Normal knee range of motion varies slightly between individuals and measures approximately 0° to -5° of extension to 140° of flexion. A full arc of motion is required for normal gait and knee function. Loss of normal joint range of motion may occur after a traumatic knee injury and may contribute to increased pain, lower functional outcome scores, and decreased patient satisfaction. Although multiple factors may contribute to the development of motion loss, the occurrence of intra-articular scar tissue adhesions, or post-traumatic arthrofibrosis, may limit the patient's knee motion in the early postoperative period. Once motion loss has been identified, it can be a challenging complication to manage. Arthroscopic lysis of adhesions with manipulation under anesthesia is a reliable surgical technique that can improve range of motion in patients with knee stiffness due to post-traumatic arthrofibrosis.
正常膝关节的活动范围在个体之间略有差异,大约从伸展0°至 -5°到屈曲140°。正常步态和膝关节功能需要完整的活动弧度。膝关节外伤后可能会出现正常关节活动范围的丧失,这可能会导致疼痛加剧、功能结局评分降低以及患者满意度下降。尽管多种因素可能导致活动丧失的发生,但关节内瘢痕组织粘连或创伤后关节纤维性强直的出现可能会在术后早期限制患者的膝关节活动。一旦发现活动丧失,它将是一种具有挑战性的并发症,难以处理。在麻醉下进行手法操作的关节镜粘连松解术是一种可靠的外科技术,可改善因创伤后关节纤维性强直导致膝关节僵硬患者的活动范围。
