When a tourniquet is used during surgery on the extremities, pressure applied to muscles, nerves and blood vessels can cause neuromuscular damage that contributes postoperative weakness. The hypothesis was rehabilitation-related results would be improved if total knee arthroplasty (TKA) performed without use of tourniquet.81 patients with osteoarthritis who underwent TKA were randomized or tourniquet. Active flexion extension knee, pain by visual analog scale (VAS), swelling circumference, quadriceps function straight leg raise, timed up go (TUG) test measured before 3 months after surgery.ANCOVA revealed no between-groups effect for at day postsurgery. Compared group, nontourniquet group experienced elevated 24 h, mean difference 16.6 mm, p = 0.005. mobility (TUG test) better in -1.1 s, 0.029.The not supported results. this study are compared, clear benefit either procedure observed, as more exhibited only evident short period clinically relevant level.Inconsistent results, Level II.
