Little is known about the functional performance of patients after
revision total hip arthroplasty with major acetabular bone impaction grafting. In
general, these patients are assumed to perform worse due to a more advanced stage
of periarticular tissue degeneration and multiple surgeries compared with
patients with primary total hip arthroplasty (THA).
The main purpose
of this study was to quantify the differences in performance of the sit-to-stand
(STS) movement between patients with primary THA and patients with revision THA.
In this study, the STS movement was analyzed kinematically
(knee and hip angular extension velocity) and kinetically (loading symmetry
ratio). Ten patients after primary THA and 10 patients after revision THA with
acetabular bone impaction grafting were compared using these 3 rising parameters.
RESULTS: The patients with revision THA performed the STS movement comparably to
the patients with primary THA; there were no differences in knee and hip velocity
or leg asymmetry during rising. LIMITATIONS: The study focused only on kinetic
and kinematic aspects, and only patients who were satisfied with their THA were
involved. CONCLUSIONS:
This study showed that patients after a revision THA with
acetabular bone impaction grafting and cement did not perform the STS movement
differently, either kinematically or kinetically, compared with patients with a primary THA.
