Improved surgical techniques and multidisciplinary rehabilitation protocols that involve coordination among surgeons, physical therapists, anesthesiologists, and social services personnel have led to excellent knee function and range of motion in a large percentage of patients following total knee arthroplasty. Nevertheless, there remains a small number of patients with persistent dysfunction that is difficult to treat1-4. Functional problems following total knee arthroplasty may be incapacitating as a result of persistent pain5, instability6, and a limited range of motion7. It has been shown recently that there is a direct correlation between a decreased range of motion following surgery and a lower perceived quality of life as evaluated with use of the Short Form-36 health survey questionnaire8. Continued dysfunction for any reason ultimately leads to decreased patient satisfaction.
