Intratendinous Platelet-rich Plasma Injection and Percutaneous Needle Tenotomy in the Treatment of Hip Tendinopathies: A Retrospective Study

Abstract

BackgroundBoth conservative and surgical treatment options for tendinopathies often have less than ideal outcomes. Platelet-rich plasma (PRP) has become an increasingly popular treatment option with only limited evidence for effectiveness. MethodsA retrospective review was performed of all consecutive patients undergoing PRP for hip tendinopathies during a three-year period in a single outpatient spine and musculoskeletal clinic. Each procedure was performed under ultrasound guidance with a concurrent needle tenotomy. Categorical data analysis was performed to determine percent of patients achieving at least 30%, 50%, and 80% relief of pain as measured by NRS. ResultsA total of 48 patients were included with an average follow period of 14 weeks. Seventy-seven percent of patient achieved at least 30% improvement in pain by NRS (95% CI: 63%-88%), 65% achieved at least 50% improvement in pain (95% CI: 49%-78%), and 27% achieved at least 80 % pain improvement (95% CI: 15%-42%). ConclusionThis retrospective study demonstrates relatively good outcomes for this novel treatment. The results of this single practice audit are similar to previously published retrospective and prospective trials.
