[Effectiveness of peri-articular infiltration with local anesthetic and adjuvants for post-surgical pain control in total knee replacement].

Introduction: Total knee arthroplasty (TKA) is one of the most successful orthopedic treatments, however, it has been associated with severe postsurgical pain in 30-60% of patients. We propose that infiltration of the articular capsule of the knee during surgery will decrease postsurgical pain.

Material And Methods: Experimental, randomized, double-blind study in patients undergoing unilateral TKA between April 2018 and January 2019.
