Functional Problems and Arthrofibrosis Following Total Knee Arthroplasty

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.
