摘　　要：Objective： To evaluate the effectiveness ofJudet＇s quadricepsplasty for treatment of knee contractures and to identify the effect of local infiltration of epinephrine on blood loss associated with this procedure. Methods： A retrospective cohort study was conducted in which all cases of knee contractures managed with Judet＇s quadricepsplasty from 1st January 2009 to 31st December 2013 were included and were divided into two groups. The epinephrine group included patients who were infiltrated with diluted epinephrine （1：400,000） along with xylocaine, around the operative field 15 min prior to the incision time, while the control group did not receive any infiltration. Judet＇s outcome, blood loss, drop in he- moglobin and required blood transfusion were noted for all patients and compared between both groups. Results： Most common preceding pathology identified for the development of knee contractures was periarticular fracture while ilizarov application was the most common etiology. Both groups were found similar in all preoperative characteristics except preoperative flexion contracture （p = 0.02）. All func- tional outcome measures including Judet＇s outcome were similar in both groups. In contrast, duration of surgery （p = 0.01）, blood loss （p = 0.02）, drop in hemoglobin （p = 0.01） and number of transfusions （p = 0.03） were significantly reduced in epinephrine group. Conclusion： Judet＇s quadricepsplasty is a useful procedure to increase the range of motion of rigid knees and local infiltration of epinephrine is effective in decreasing the amount of subsequent blood loss and transfusion requirements.
