Kinesiology after McKee-Farrar total hip replacement. A two-year follow-up of one hundred cases
MP Murray, BJ Brewer, DR Gore and RC Zuege
Measurements of functional performance were made before and at six and
twenty-four months after 100 McKee-Farrar total hip replacements in
eighty-three patients. The measurements included: range of motion of the
hip, hip-muscle torque, weight-bearing activity during standing, forces
applied to canes or crutches, and multiple components of walking
performance. In the absence of serious complications, most patients had
improvement in most components of function, with greater gains occurring
during the first six months and lesser but continued gains between the
sixth and twenty-fourth postoperative months. Patients with serious
operative complications, postoperative infections, or component loosening
showed declines in almost every component of function tested.
