Technique of Correction of Flexion Contracture During Total Knee Arthroplasty

Abstract

Flexion deformity of varying degree is common in the arthritic knee. The deformity may be solely flexion but more commonly it is combined with mediolateral and/or rotatory malalignment. The osteoarthritic varus knee will frequently have a mild to moderate (less than 30°) concomitant flexion contracture. In more severely damaged knees, particularly those of patients with juvenile rheumatoid arthritis or hemophiliac arthropathy, flexion deformity may be considerable. The attitude of valgus deformity with a significant flexion contracture and severe external rotation of the knee is seen in these patients and presents major difficulties in correction.
