(AP Photo/John Minchillo) Does your cat know when it’s time to be fed? Does your dog know what time you arrive home from work? The world animals experientially inhabit is far removed from our human world – and this extends to their perception of time. This doesn’t mean time is just subjective however, in fact the differences between our human perception of time and animal time suggests an objective time by which we measure these differences against, writes Samuel Baron.

Purpose The purpose of this double-blind, randomized, controlled trial was to evaluate the use of intravenous (IV) tranexamic acid (TXA) in patients undergoing primary bone–patellar tendon–bone (BPTB) anterior cruciate ligament reconstruction (ACLR) regarding postoperative hemarthrosis, pain, opioid consumption, and quadriceps atrophy and activation. Methods A controlled, randomized, double-blind trial was conducted in 110 patients who underwent ACLR with BPTB autograft.

Purpose To determine whether postoperative acetaminophen reduced narcotic consumption following hip arthroscopy for femoroacetabular impingement. Methods This was a single-center randomized controlled trial. Opioid-naïve patients undergoing hip arthroscopy for femoroacetabular impingement were randomized into 2 groups.
