title: Total condylar knee arthroplasty for valgus and combined valgus-flexion deformity of the knee.
abstract: Total condylar knee arthroplasty was performed on 64 knees with fixed valgus or valgus/flexion deformities. The technique for release of tight lateral and posterior structures is important to balance the ligament. Clinical results were rated good and excellent in 95% of the knees. Four patients with excessive flexion deformities required 6 weeks of cast bracing in the immediate postoperative period for instabilities caused by an imbalance in the spacing in flexion and extension. In no joint in the entire series did stability deteriorate with time. There were no patellar complications or nerve palsies noted. Radiographic evaluation revealed well-fixed components in 92% of the arthroplasties. None has required revision for mechanical loosening to date. With proper technique the total condylar prosthesis can be employed in knees with valgus or valgus/flexion deformities to give predictably good results. The total condylar III prosthesis may be required in severe combined deformities for added stability.
