RESUMO
INTRODUCTION: The management of postoperative pain in joint replacement surgery represents a challenge. Therefore, the advent of new strategies in the management of pain such as local infiltration analgesia (LIA) and the adductor canal block, allowed an adequate postoperative pain control and early rehabilitation of the patient in total knee arthroplasty. MATERIALS AND METHODS: A descriptive, observational and longitudinal study of a prospective cohort of patients operated by the group of joint replacements between September 29, 2017 and November 30, 2017 was conducted. They were evaluated with the analog pain scale for postoperative pain at 5 different times (1:Upon leaving recovery; 2:On the first postoperative day; 3:Before initiating in-hospital physical therapy; 4:At the end of physical therapy, and 5:Upon departure from the clinic). RESULTS: Of the 141 patients operated on, 70.9% of the patients were managed with LIA and 29.1% with adductor canal block. There were no differences between groups in postoperative pain assessment during the 5 different times (P≥.45). DISCUSSION: Our results indicate that LIA and the adductor canal blockade demonstrated the same efficacy for the control of postoperative pain and rehabilitation.
