Abstract
PURPOSE: This study was undertaken to determine the efficacy of reinflation of the tourniquet after its early release in TKA compared to early release alone, in terms of surgical field visualization and operative time. We also questioned whether tourniquet reinflation after its early release is safe, with respect to post-operative blood loss, post-operative pain and other tourniquet-related complications. METHODS:Two hundred and six patients undergoing TKA were randomly allocated to either the early release (deflation) group (n = 105) or reinflation after early release (reinflation) group (n = 101). Efficacy was measured in terms of surgical field visualization, specifically the number of wound clearances, and operative time. Safety outcomes were drained volume, decline in haemoglobin on post-operative days 2 and 5, the frequency of transfusion, knee and thigh pain visual analog scale, local wound complications, tourniquet site complications and other complications, including infection, deep vein thrombosis and pulmonary embolism. RESULTS:Surgical field visualization was better in the reinflation group; however, the operative time did not differ between the two groups. There were no differences between the two groups in post-operative blood loss, decline in haemoglobin on days 2 and 5, transfusion rate, pain level, local complications and other complications. CONCLUSION: Reinflation of tourniquet is a safe alternative to its early release after deflation in that it improves surgical field visualization during TKA. LEVEL OF EVIDENCE: Therapeutic study, Level I.
