Total knee arthroplasty for rheumatoid knee with bilateral, severe flexion contracture: report of three cases

Abstract: The treatment of patients with severe flexion contracture of the rheumatoid knee, deprived of ambulation for long periods of time, is challenging. Based on three cases, we indicate the potential risks of posterior dislocation of the knee after total knee arthroplasty. In this pathological condition, surgeons must carefully select the type of implant in order to avoid this serious complication. We also emphasize the importance of working on disuse muscle atrophy of trunk (back, abdominal) and lower limbs, both … Show more

“…Distal femoral resection more than 4 mm positions the joint line more proximally, which functionally lengthens the collateral ligaments and posterior capsule towards extension, without compromising stability in flexion. However, caution should be exercised in performing additional resection, since overzealous bone resection on the femoral side could alter patella-femoral kinematics and over-resection of the proximal tibia could lead to instability [5,6], while under-resection will leave behind residual flexion contracture [7]. Intra-operatively, on extension we observed that the posterolateral soft tissue sleeve was contracted.…”

“…However, it is potentially a poor strategy, as more bony cuts are needed to get the knee straight in the operation of patients with severe flexion contracture, which creates more problems with respect to instability thereby causing pain and dysfunction 8,9 .…”
