A study presented at the American Association of Hip and Knee Surgeons Annual Meeting found that manipulation under anesthesia (MUA) with or without lysis of adhesion (LOA) after total knee arthroplasty can provide a gain of 30° of knee flexion. While the improvement declined after 90 days, MUA showed similar results to LOA with a lower risk of loss of flexion and comparable complication profiles. Patients who failed tended to have a higher comorbidity index and the cruciate retaining type of bearing was more likely to fail early. Overall, both MUA and LOA groups experienced an intraoperative gain in knee flexion that declined at first postoperative visit before being regained.
