Lower total blood loss in total knee arthroplasty with a low-pressure tourniquet than without

Tourniquet-use has been described in litera- ture as a surgical factor leading to increased post-operative hidden blood loss total knee arthroplasty (TKA). The hypothesis for this retro- spective study was that low-pressure tourniquet TKA would offer the benefits of surgery without potential negative effects on late after procedure. Therefore, evaluated (TBL) and (HBL) with or tourniquet. We retrospectively compared two groups : one group (n= 54) undergoing 110). outcomes were hemoglobin levels 2 weeks before at days 4 calculate loss, transfusion rate, functional outcome. A higher observed no mean 1073 mL against 890 (p-value = 0,003). Hidden values between both statistically not significant no-tourniquet group, Hb drop D2 D4 0.5 g/dL 0.4 g/ dL group. tourniquet-less did present better scores. This showed low- pressure use reduces TBL increasing HBL TKA.
