Objective:
Pes anserine bursitis is the most common cause of periarticular knee pain. The aim of the study was to evaluate the efficacy of local injection-based therapies with different materials.
Design:
The enrolled patients were randomly allocated to three groups to receive different interventions. Outcome measures included pain severity using the visual analog scale and the Western Ontario and McMaster Universities osteoarthritis index that was evaluated before the intervention, 1 and 8 wks after that.
Results:
This trial was performed on 72 participants, with male-to-female ratio of 0.14 and with a mean age of 61.49 ± 9.35 yrs. Corticosteroids in the first group, oxygen-ozone in the second group, and dextrose 20% in the third group, were injected into the pes anserine bursa under ultrasound guidance. Interaction between time and group showed a statistically significant improvement in visual analog scale and Western Ontario and McMaster Universities Arthritis Index ( P ≤ 0.05) in favor of corticosteroids and oxygen-ozone groups after 1 wk and in favor of oxygen-ozone and prolotherapy groups after 8 wks.
Conclusions:
All three treatment options are effective for patients with pes anserine bursitis. This study showed that the effects of oxygen-ozone injection and prolotherapy last longer than those of corticosteroid injection.
