BACKGROUND: Oral and topical nonsteroidal anti-inflammatory drugs (NSAIDs), analgesics and intra-articular corticosteroid injections are the recommended first line of treatment for knee osteoarthritis (OA); however, they have serious side effects. Platelet-rich plasma (PRP) has been posited as an effective and safer alternative treatment for knee OA. Hitherto, there is only one study comparing the effectiveness of PRP against an NSAID. AIM OF THE STUDY: The aim of this study was to determine the effectiveness of PRP against celecoxib in the treatment of early knee OA. METHODS: 60 patients with knee OA grade II and III were randomly alocated in two groups. Group 1 received one injection of autologous PRP in each affected knee, with a reinjection after 15 days; Group 2 received 200 mg of oral celecoxib each 24 h for a year. Visual Analogue Scale (VAS), total Western Ontario and McMaster Universities Arthritis Index (WOMAC) and WOMAC subscales for pain, stiffness and function were measured at baseline and at 1, 3, 6 and 12 months after the start of the treatment. RESULTS: At the end of the study PRP was significantly better than celecoxib (p < 0.05) in improving VAS (40.40%), total WOMAC (58.95%) and WOMAC subscales of pain (50.60%), stiffness (34.13%) and function (51.90%). Significant differences remained after adjusting for age, sex or knee OA grade II or III. CONCLUSIONS: Intra-articular PRP is significantly better than celecoxib in improving pain, function and stiffness in early knee OA. This significant difference is independent of age, sex or knee OA grade II or III.
