RESUMO
BACKGROUND/AIM: Osteoarthritis is one of the most common degenerative conditions that causes pain, stiffness, and decreased functionality. The management of knee osteoarthritis necessitates collaboration among specialists from different disciplines, considering the primary clinical manifestations and functional level of the disease. The aim of this study was to highlight the disparities in postoperative outcomes between knee arthroplasty procedures with and without non-steroidal anti-inflammatory drugs (NSAIDs). The study specifically focuses on the immediate advantages and outcomes observed at the 6-month milestone. PATIENTS AND METHODS: This study followed 713 patients who were randomly divided into two groups: a group that did not receive non-steroidal anti-inflammatory drugs (N-NSAIDs) consisting of 394 patients, and a group that received non-steroidal anti-inflammatory drugs (NSAIDs) comprising 319 patients. The study spanned a duration of 5 years (2018-2022), with patients being followed and evaluated for up to 6 months after the surgery. RESULTS: It was observed that, from a therapeutic standpoint, the use of injectable treatments decreased. Significantly better differences were recorded in the N-NSAIDs group regarding return to pre-osteoarthritis activities at 6 months and reduced or absent night pain at 3 months (p<0.05). CONCLUSION: Statistically significant improvements were observed in the N-NSAIDs group concerning the ability to resume pre-osteoarthritis activities within 6 months, as well as a reduction or absence of nighttime pain within 3 months.
