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.
