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

Completed · Not applicable

Conditions studied: Chronic Tendinopathy

In brief

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.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• aged 18-100 years
• pain (≥ 5/10 pain on the VAS) that is a direct result of tendinosis as determined by history of injury and study team member physician's best judgment and review of medical records, imaging studies, etc.
• Tendinosis will be confirmed by clinical and ultrasonographic examination by the PI
• ≥3 months of pain after injury that has failed conservative treatments or after corticosteroid (CSI) (must be 3 months after CSI to avoid theoretical tendon rupture)

You may not qualify if…

• taking coumadin or other anti-coagulant or anti-platelet medication
• known coagulopathy or bleeding dyscrasia
• current or recent fluoroquinolone prescription
• prior PNT or PRP for the affected tendon(s)
• known systemic illness such as vasculitis, an autoimmune or an inflammatory disease, or uncontrolled diabetes
• presence of other musculoskeletal injury or tendon rupture in the region
• currently are or plan to become pregnant during the study.
• Patients taking aspirin or NSAIDs are not excluded.
