Judet quadricepsplasty for extension contracture of the knee.

Extension contracture of the knee is a well known complication of severe femoral fractures, especially in the supracondylar region. Traditional management by the Thompson quadricepsplasty may result in a variable return of knee flexion and the possibility of significant extension lag. The Judet technique of quadricepsplasty offers the advantages of a controlled, sequential release of the intrinsic and then the extrinsic components limiting knee flexion and a reduced potential for iatrogenic quadriceps rupture or extension lag. The modified Judet quadricepsplasty has definite advantages over the Judet technique since it usually involves less soft tissue dissection and consequently less blood loss.
