Abstract：Objective To investigate the causes and the clinical effects of postoperative wound complications following total knee arthroplasty ( TKA ) retrospectively.Methods From January 2011 to January 2014,612 cases ( 798 knees ) underwent primary TKA.24 cases ( 28 knees ) were of postoperative wound complications.The factors of etiology,gender,side,diabetes and duration of tourniquet use were analyzed to determine the cause of postoperative wound complications.Results were analyzed.Results Postoperatively,24 cases ( 28 knees ) had wound complications and the incidence rate was 3.9％.Poor wound healing occurred in 13 cases ( 16 knees ) within one week during the dressing change postoperatively,disappearing after conservative treatment.Necrosis,disruption,sinus track formation appeared in 11 cases ( 12 knees ) after the removal of stitches.Two cases ( 2 knees ) had open debridement,antibiotic bone cement implant and two-stage revision.Other cases recovered after symptomatic regular treatment.Among those 24 cases,patients with rheumatoid arthritis,diabetes and longer tourniquet use had a higher incidence rate of wound complications than regularly treated patients,with statistical significance (P＜0.05 ).Conclusions Patients with rheumatoid arthritis and diabetes are more likely to have wound complications after TKA.With good preoperative preparation and short duration of tourniquet application,the incidence rate of complications may decrease.It is necessary to make early deifnitive diagnosis of postoperative wound complications and provide proactive treatment.
