| Abstract |
Abstract Bilateral total knee arthroplasty
for a painful stiff knee was performed in a 50-year-old woman with
rheumatoid arthritis who had spontaneous fusion of the right hip.
Despite several manipulations, the range of motion of the right
knee worsened. After total hip arthroplasty and ipsilateral knee
revision, the right knee had a stable range motion of m15° to 75°.
This case suggests that even if the ankylosed hip is in a good
position, ipsilateral knee arthroplasty with a fused hip may result
in a poorer range of motion than that after total hip arthroplasty.
