The long-term outcome of total knee patients with moderate loss of motion.

This study determined the outcome of total knee replacement (TKR) patients with moderate loss of motion who received no particular treatment. Twenty patients with an average arc of motion of 8 degrees-91 degrees of flexion 3 months postoperatively underwent 3-year follow-up. No formal treatment was given. All patients' range of motion and Knee Society scores improved over time. Most of the improvement occurred by 2 years. Patients with moderately stiff TKRs continue to improve over time without vigorous, prolonged physical therapy, manipulation, or bracing.
