The Efficacy of Ultrasound Guided Percutaneous Needle Tenotomy (PNT) Versus Platelet Rich Plasma (PRP) With PNT in the Treatment of Chronic Tendinosis

Hospital for Special Surgery, New York·interventional·Posted Apr 17, 2013·Updated Dec 23, 2020

In Brief

A clinical study evaluating PNT + PRP and PNT alone for Chronic Tendinopathy. Completed, enrolled 40 participants across 2 sites.

Detailed Summary

Tendinopathy is a clinical syndrome of chronic pain and tendon degeneration that impairs a person's ability to perform daily activities and recreation. Traditional conservative treatments include activity modification, exercises, ice/heat, and medications and corticosteroid injection. A newer treatment is percutaneous needle tenotomy (PNT), in which the affected area is repetitively needled to disrupt pathological tissue and induce bleeding. This turns a nonhealing chronic injury into an acute injury with enhanced healing capability. Another is Platelet Rich Plasma (PRP), whereby patients' own platelets are injected into the affected area, also activating growth factors. There has been promising research in these tendinopathy treatments but more research is needed. The investigators plan to expand on prior studies to identify a reproducible and efficacious treatment for chronic tendinopathy to reduce pain and improve function and quality of life. Our goal in this study is to assess the efficacy of ultrasound guided (USG) PNT versus PNT with peritendinous PRP as a treatment for chronic tendinopathy.

Interventions

PNT + PRPprocedure

The PNT + PRP group will undergo needle tenotomy under direct and continuous ultrasound guidance with even distribution of PRP into the peritendinous area(s) of PNT around the affected tendon.

PNT aloneprocedure

The PNT group will undergo needle tenotomy under direct and continuous ultrasound guidance local anesthesia into the affected tendon. 10 minutes after the injection, the ultrasound machine probe will be passed over the areas treated both to evaluate for any structural changes and for any complications.
