Abstract: BACKGROUND: Osteoarthritis (OA) is a chronic disease most often occurring in knee joints, leading to pain of varying severity and deterioration in daily living activities. OBJECTIVE: To compare efficacy of platelet-rich-plasma (PRP) versus PRP in combination with ozone gas injection in patients with early stage knee OA. METHODS: Retrospective data of patients who received PRP alone (n= 45) or combined treatment (PRP + ozone, n= 35) injection was analyzed. Patients were evaluated using the visual analogue scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores. RESULTS: In both PRP alone and combined treatment groups, post-treatment VAS and WOMAC scores at month 1, month 3, and month 6 showed a significant reduction compared to pre-treatment scores (p< 0.001). Physical function and total WOMAC scores as well as VAS scores at post-treatment month 3 were significantly lower in the combined treatment group compared to the PRP alone group. Moreover, in the combined treatment group, VAS scores on Day 10 and hyper-inflammation at the injection site was significantly lower than the PRP alone group. CONCLUSION: In general, similar efficacy was observed between treatment with PRP alone and treatment with PRP in combination with ozone. However, patients receiving ozone treatment are less likely to experience post-injection pain and are more likely to recover faster when compared to patients receiving PRP treatment alone.
