Abstract

To see the clinical result of Modified Judet’s Quadricepsplasty (MJQP) with patella traction at BARI-ILIZAROV ORTHOPAEDIC CENTRE for the treatment of knee extension contracture. Materials and methods: We received 16 patients with knee extension contracture treated by MJQP with patella traction from January 2015 to January 2021, at our BARI-ILIZAROV ORTHOPAEDIC CENTRE. The age at revision surgery was 25-58 years. The time between fracture treatment to MJQP was 4 to 20 months and our follow up was 10-30 months. We assessed pre-operative and post-operative range of motion (ROM). Results: Knee range of motion pre-operatively was 5-50 (35± 10)° and 35-85 (55±10)° after MJQP and in average of 0-35(18+10) °. We applied patella traction for 12-14 (10±3)° days. When we removed the patella traction the knee range of motion at that time was 95-110 (93±4)° and increase of 10-70 compared with the range of motion after release of all arthrofibrosis in the joint. Our follow up time was 12-35 (19±5) months. Knee range of motion at first follow up was 85-135 (105±13)°, an increase of 45-105 (70±15) ° compared with pre-operatively and of 10-45 (12±12)° compared with the range of motion after patella traction removed. Knee function was excellent in 12 cases (70%), good in 3 (27%) and fair in one (3%). Conclusion: MJQP with patella traction lengthens the contracted Quadriceps femoris gives excellent result with proper post-operative care and CPM therapy.
