    Abstract:
    The technique of total knee arthroplasty for the patients with severe flexion contractures of more than 60 degrees is not clear. Recently, We have performed 37 total knee arthroplasties in 23 patients with flexion contracture of more than 60 degrees (average 77.97 degrees). Among them, 14 knees (37.9%) with flexion contracture of more than 90 degrees, and 7 knees (18.0%) with 90 degrees flexion fusion deformities. Significant improvements occurred after averaged 4.3-year follow-up. Complications occurred in four patients: three had transient peroneal-nerve palsy, and one had temporary circulatory disturbance of the lower extremity. They recovered after conservative therapy. We consider that severe flexion contracture of more than 60 degrees is not a contraindication of TKR. Staged bone resection and thoroughly soft-tissue release of the posterior capsule and collateral ligament balance were the critical procedure. If necessary, additional distal femoral condyle resection with posterior cruciate ligment sacrifice can be considered.
