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.
