Abstract
AIMS: This study aimed to compare the efficacy and safety of pre-operative and post-operative meloxicam administration regarding post-operative pain control and knee joint function recovery in knee osteoarthritis (KOA) patients who underwent total knee arthroplasty (TKA). METHODS: Totally, 196 KOA patients who underwent TKA were consecutively enrolled and randomly assigned into pre-operative (N = 98) and post-operative administration group (N = 98) as 1:1 ratio. Pre-operative administration group received meloxicam 15 mg at 24 h pre-operation and 7.5 mg at 4 h, 24 h, 48 h, and 72 h post-operation, respectively. Post-operative administration group received meloxicam 15 mg at 4 h post-operation and 7.5 mg at 24 h, 48 h, and 72 h post-operation, respectively. Pain visual analog scale (VAS) at rest and at flexion, patient's global assessment (PGA), patient-controlled analgesia (PCA) consumption, hospital for special surgery (HSS), knee score, and adverse events were assessed. RESULTS: Pre-operative meloxicam administration attenuated pain VAS score at rest at 6 h, 12 h, and 24 h; and pain VAS score at flexion at 6 h, 12 h, 24 h, and 48 h; as well as PGA score at 6 h, 12 h, 48 h post-TKA compared with post-operative meloxicam administration. Additional and total consumption of PCA were both decreased in pre-operative meloxicam administration group than post-operative meloxicam administration group, while HSS knee score at 3 months post-TKA was similar between pre-operative and post-operative meloxicam administration groups. Regarding safety, the incidence of adverse events was of no difference between the two groups. CONCLUSION: Pre-operative administration of meloxicam might assist the post-operative pain management and care in KOA patients who underwent TKA.
