This study investigates the effect of early tourniquet release on range of flexion following total knee replacement, and the influence of anticoagulation with Rivaroxaban and Clexane (Enoxaparin). 78 patients were included in the study, who underwent unilateral primary total knee replacement (TKR) in our department under the care of two specialist knee surgeons over a 12 month period. 27 patients underwent TKR with early release of the tourniquet and haemostasis, prior to closure of quadriceps layer: 22 were anticoagulated with Rivaroxaban (GROUP ER), 15 with the low molecular weight heparin Clexane (GROUP EC). Over the same time period, 41 patients TKR with late release of the tourniquet, following closure and bandaging: 13 were anticoagulated with Rivaroxaban (GROUP LR), 28 with Clexane (GROUP LC). A standardised operative technique was employed, and all patients received an AGC (Biomet) PCL-retaining prostheses. Outcome was assessed with range of flexion at 12 weeks postoperatively.Purpose
