    TREATMENT OF CHRONIC ELBOW TENDINOSIS WITH BUFFERED PLATELET-RICH PLASMA

    Mishra A, Pavelko T. Am J Sports Med 2006;34:1774–8

    Background:

    A small percentage of patients with chronic epicondylar tendinosis of the elbow do not respond to non-operative treatment; however, many are still considering non-operative treatment options.

    Research question/s:

    Does local infiltration with buffered platelet-rich plasma reduce pain and increase function in patients suffering from chronic severe elbow tendinosis who are considering surgery?

    Methodology:

    Subjects:

    20 of 140 patients presenting with chronic elbow epicondylar pain that has not responded to non-operative treatment following a standardised physical therapy protocol and other non-operative treatments.

    Experimental procedure:

    20 patients with significant persistent (mean 15 months) pain (mean of 82; 60–100 pain on VAS 0–100 scale) and who were considering surgery were allocated in a non-randomised fashion to either a single percutaneous injection of platelet-rich plasma (PRP = 15) or bupivacaine (LA group = 5). Subjects were assessed before and after 1, 2 and 6 months after intervention.

    Measures of outcome:

    Pain (VAS 0–100), elbow function (Mayo elbow score, best = 100).

    Main finding/s:

    • 3 of the 5 subjects in the LA group withdrew or sought other treatments after the 8-week period, which prevented further analysis.

    • Subjects in the PRP group reported significantly higher Mayo elbow scores at 2 months compared with the LA group.

    Conclusion/s:

    In a non-randomised pilot study, treatment …
