Résumé
OBJECTIVE@#To investigate the causes of poor incision healing after total knee arthroplasty(TKA) and to propose active preventive and therapeutic measures.@*METHODS@#Total 284 patients undergoing unilateral TKA from September 2016 to June 2018 were enrolled in the study and divided into control group and observation group. Firstly, 150 patients with unilateral TKA from September 2016 to June 2017 were retrospectively analyzed and included in the control group. There were 41 males and 109 females, with an average age of(63.5±7.2) years old. The causes of poor incision healing were discussed about patients themselves and surgical techniques. After analyzing, improvement measures were proposed. Total 134 patients with TKA from July 2017 to June 2018 were included in the observation group. There were 36 males and 98 females, with an average age of(62.4±8.9) years old. The patients in the observation group were treated with improved treatment strategies.@*RESULTS@#Nine patients(6%) had poor incision healing in the control group and 1 patient (0.75%) had poor incision healing in the observation group. The incidence of poor incision healing was significantly different between the two groups (²=5.750, <0.01).@*CONCLUSIONS@#In order to prevent the poor incision healing after TKA, perioperative management and the operation techniques including stable, accurate, rapid and clean skills should be improved, leading to reduce the complications of incision and improve the recovery rate of patients.
