چکیده

Arthrofibrosis after total knee arthroplasty (TKA) is a potentially devastating complication, resulting in loss of motion and function and residual pain. For patients in whom aggressive physical therapy and manipulation under anesthesia fail, lysis of adhesions may be the only option to rescue the stiff TKA. The purpose of this study is to report the results of arthroscopic lysis of adhesions after failed manipulation for a stiff, cruciate-substituting TKA. This retrospective study evaluated patients who had undergone arthroscopic lysis of adhesions for arthrofibrosis after TKA between 2007 and 2011. Minimum follow-up was 12 months (average, 31 months). Average total range of motion of patients in this series was 62.3°. Average preoperative flexion contracture was 16° and average flexion was 78.6°. Statistical analysis was performed using Student's t test. Pre- to postoperative increase in range of motion was significant (P<.001) (average, 62° preoperatively to 98° postoperatively). Average preoperative extension deficit was 16°, which was reduced to 4° at final follow-up. This value was also found to be statistically significant (P<.0001). With regard to ultimate flexion attained, average preoperative flexion was 79°, which was improved to 103° at final follow-up. This improvement in flexion was statistically significant (P<.0001). Patients can reliably expect an improvement after arthroscopic lysis of adhesions for a stiff TKA using a standardized arthroscopic approach; however, patients achieved approximately half of the improvement that was obtained at the time of surgery.

Arthroscopic lysis of adhesions for the stiff total knee arthroplasty.

The management of the stiff knee after total knee arthroplasty is controversial. Manipulation under anesthesia and open lysis of adhesions are techniques that can theoretically address the fibrous scar tissue, but their efficacy has been shown to be variable. We describe the technique of arthroscopic lysis of adhesions for the stiff knee after total knee arthroplasty. The advantages of this tec...

Arthroscopic lysis of adhesions for stiff total knee arthroplasty.

The goal of this study was to evaluate the efficacy of arthroscopic lysis of adhesions after total knee arthroplasty (TKA) in improving range of motion (ROM) and providing an improvement in knee function. The authors retrospectively examined 19 patients who underwent arthroscopic lysis of adhesions following TKA due to poor ROM. The criterion for lysis was the inability to flex to 90° at 3 mont...

Outcome Of Arthroscopic Arthrolysis Of Arthrofibrosis After Total Knee Replacement

Introduction Chronic pain and stiffness occurring after total knee arthroplasty are frustrating for both the patient and the surgeon. After total knee arthroplasty (TKA), there is a relatively small group of patients who develop a painful joint with suboptimal range of motion (ROM) despite optimal surgical technique and good radiographic appearance. Arthrofibrosis, for the most part, is an unco...

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

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 mu...

Compartment Syndrome of the Thigh Following Manipulation to Treat Knee Stiffness after Total Knee Arthroplasty

A 67-year-old man developed compartment syndrome of the thigh following manipulation for treatment of knee stiffness after a total knee arthroplasty. Three months earlier, he had undergone arthroscopic synovectomies twice for treatment of septic arthritis in the same leg. Manipulation for treatment of stiffness concomitant with periarticular inflammation is a possible risk factor of compartment...
