Alexandersson M, et al. - Experts tested the presumption that there would be better rehabilitation-related results if total knee arthroplasty (TKA) was performed without the use of a tourniquet. Participants were 81 patients with osteoarthritis of the knee who underwent TKA surgery. Findings did not support the hypothesis. Comparing the results in this study, neither procedure demonstrated any clear benefit; while more pain exhibited by the nontourniquet group, it was only for a brief time. The improved mobility in the nontourniquet group was not at a clinically relevant level.
