Platelet-rich plasma for treatment of ischiogluteal bursitis / 中国组织工程研究

ABSTRACT

BACKGROUND:Ischiogluteal bursitis has been recognized for a long time, but its treatment stil limits to local blocking injection and surgery methods that were developed 40 years ago. OBJECTIVE:To observe the efficacy of platelet-rich plasma on ischiogluteal bursitis. METHODS:Data of 15 patients with ischiogluteal bursitis were colected. Al the patients with ischiogluteal bursitis were treated with bilateral platelet-rich plasma (n=10) or local blocking injection (n=5). Patients’ outcomes were assessed by visual analogue scale, the Treatment Satisfaction Questionnaire for Medication (TSQM) Version II and recurrence rate. The folow-up time was from 6 to 14 months. RESULTS AND CONCLUSION: There was no statistical difference in visual analogue scale score between the platelet-rich plasma group and local blocking group (F=0.219,P=0.643), but the score of visual analogue scale in the platelet-rich plasma group was higher during short-term folow-up (within 1 week after treatment), but lower in the long-term folow-up. In the aspects of overal satisfaction score, clinical effectiveness and side effects, the platelet-rich plasma group was inferior to the local blocking group at short-term folow-up, especialy at 1 week after treatment; however, these scores became better in the platelet-rich plasma group than the local blocking group during the long-term folow-up period. In addition, no statistical difference in the convenience score was found between the two groups. At the last folow-up, the recurrence rate in the platelet-rich plasma group was lower than that in the local blocking group. Both the platelet-rich plasma and local blocking injection can significantly reduce the pain of patients with ischiogluteal bursitis. Local blocking injection has better short-term effectiveness. Platelet-rich plasma injection works moderately, but its effectiveness can last for longer time, and the recurrence rate is lower.
