Brief Summary
The overall goal of this proposal is to correlate ultrasound elastography technique with more standard clinically based outcome measures within the setting of a small sample sized group of patients affected by moderate-to- severe, chronic (\>6months) midsubstance Achilles tendinopathy (AT).

Outcome Measures
Primary Outcomes (1)
Structure and Biomechanical function
Primary outcome measure: Estimate ultrasound based changes consistent with disease modification in two ways: 1. conventional ultrasound to assess Achilles tendon thickness, neovascularity, and hypoechogenicity. 2. estimate AE and SWI variability and the correlations of AE and SWI with conventional ultrasound measures to plan future research.

Study Arms (2)
Autologous Platlet Rich Plasma
EXPERIMENTALThis subject arm will receive one injection of autologous platelet rich plasma for the treatment of Achilles tendinopathy. In addition, they will be asked to undergo a palpatory exam of the Achilles tendon; complete Quality of Life Questionnaires at three different time points; and complete a 30 minute ultrasound imaging exam of the Achilles tendon.
Waitlist
OTHERSubjects in this arm will have already received standard of care interventions for Achilles tendinopathy with unsatisfactory outcomes. For this research they will be asked to undergo a palpatory exam of the Achilles tendon; complete Quality of Life Questionnaires at three different time points; and complete a 30 minute ultrasound imaging exam of the Achilles tendon.
Interventions
This procedure will include a single collection of 35 mL of peripheral blood. A two-stage spinning protocol will be used: the 1st separates red blood cells from platelets, and the 2nd concentrates the platelets to yield approximately 4 mL of concentrated autologous platelet. This layer of platelet rich plasma will be placed in the syringe by the centrifuge machine.
A conventional ultrasound in addition to AE and shear wave imaging (SWI) will be administered.
This questionnaire is a self-report of pain and function associated with the Achilles tendon.
Eligibility Criteria
You may qualify if:
- age 18-65 years, inclusive
- diagnosis of moderate to severe AT, confirmed by Dr. Wilson using clinical symptoms and exam findings consistent with chronic AT (\>6 month duration) - which includes pain while palpating the intratendinous swelling part of the Achilles tendon and relief of pain when tendon placed under tension - and pre-procedure US
- self-reported AT-related pain for at least 6 months and VAS (Visual Analog Scale) pain \>5 (0-10 scale)
- self-reported failure of eccentric exercise protocol (at least 75% completion)
- self-reported failure of at least 2 of the 3 most common treatments for AT (NSAIDS, rest/ice or taping)
- patient considered surgery but decided to wait and/or refused surgery -
You may not qualify if:
- bilateral AT
- insertional AT
- local steroid injection within 6 weeks or physical therapy within 4 weeks
- inability to comply with follow-up criteria
- history of surgery on the Achilles tendon or systemic diseases (general inflammatory diseases such as rheumatologic disorders and diabetes)
- daily use of opioids for pain
- anticoagulation or immunosuppressive therapy
- intent to use NSAIDs or steroids
- self-reported pregnancy
