Arthroscopic Lysis of Adhesions for Treatment of Post-traumatic Arthrofibrosis of the Knee Joint

Abstract

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.
