Abstract
In this study, we have performed modified Judet quadricepsplasty for 20 patients who were suffering from post-traumatic extension contracture of the knee joint. Stiffness was a result of intra-articular femoral fractures in 11 cases, diaphyseal femoral fractures in 5 cases, and supracondylar femoral fractures in 4 cases. Femoral fractures were comminuted in 12 cases and simple in 8 cases. Fractures were open in 14 cases and closed in 6 cases. Femoral fractures were isolated in 16 cases and was accompanied with ipsilateral both bone leg fractures in 4 cases. All cases were males. Age of the patients was ranging from 20 to 39 years with an average of 29.9 years. The time elapsed from the trauma till quadricepsplasty (The preoperative interval) ranged from 20 to 60 months with an average of 39.15 months. The preoperative flexion ranged from 10 to 60 degrees with an average of 29.5 degrees. The intraoperative flexion ranged from 100 to 140 degrees with an average of 120 degrees. The final flexion ranged from 70 to 140 degrees with an average of 100.7 degrees. Follow-up period ranged from 6 to 40 months with an average of 20.35 months. The clinical and functional outcomes were assessed by the Knee Society Clinical Rating Score, and the final range of motion was assessed according to Judet Criteria. According to the Knee Society Clinical Rating Score, excellent outcomes were documented in 11 cases (55 %), good in 6 cases (30 %), and fair in 3 cases (15 %). According to Judet score, excellent outcomes were documented in 10 cases (50 %), good in 7 cases (35 %), and fair in 3 cases (15 %). Complications were postoperative anemia in 6 cases, early loss of knee flexion in 2 cases, superficial infection and wound dehiscence 2 cases, and postoperative hematoma in one case.
