Title: Knee ankylosis or stiffness after a total knee arthroplasty: treatment and long-term outcome
Abstract: This study reviewed 42 total knee arthroplasties in 38 patients who had a range of motion of less than 50° 2–4 weeks postoperatively. The duration of follow-up ranged from 2.3 to 19 years after the operation. All patients underwent initial treatment with physical therapy or manipulation under anaesthesia, and range of motion increased from a mean of 43° to 51° (P < 0.01). In 27 cases, one or more subsequent treatments were performed. At the last follow-up, range of motion had increased to a mean of 69° (P < 0.0001). Survivorship analysis of the knees showed that the probability of an implant not having been removed was 72% at 2 years, 67% at 5 years and 62% at 10 years. Persistent knee stiffness and flexion contracture after total knee arthroplasty are serious complications which are often resistant to treatment and are associated with a high rate of unsatisfactory long-term results.
