Comparison of warfarin use in total knee replacement vs total hip replacement.
The purpose of this retrospective study was to determine the efficacy of warfarin prophylaxis against deep vein thrombosis (DVT) in total hip arthroplasty (THA) vs total knee arthroplasty (TKA). A review of venograms in 223 patients with THA and in 189 cases of TKA was carried out. The overall DVT rate in THA was 22%. The overall DVT rate in TKA was 46%. We conclude that combined or alternate methods need to be used to decrease the rate of DVT following TKA to that of THA.
