History of Changes

Purpose

Platelet rich plasma has been used in previous studies to stimulate faster healing of torn ligaments and tendons in order to help reduce pain and restore normal function. This study aims to prove that non-operative treatment of acute and chronic ligament and tendon injuries with platelet rich plasma will reduce the time needed for participants to heal these injuries and restore function.

Arms	Assigned Interventions
Sham Comparator: Dry needling Blood will be drawn, and tendon will be penetrated with dry needle. Nothing will be injected into the tendon.	Procedure: Ultrasound-guided dry needling Blood will be drawn, and tendon will be penetrated with dry needle under ultrasound guidance. Nothing will be injected into the tendon.
Experimental: Platelet-rich plasma (PRP) Blood will be drawn, and platelet-rich plasma will be injected into the tendon.	Procedure: Ultrasound-guided platelet-rich-plasma (PRP) injection Blood will be drawn, and platelet-rich plasma will be injected into the tendon under ultrasound guidance.

Detailed Description:

Pre-procedure diagnosis: The appropriate clinical evaluation will be dictated by the examining physician. Minimal pre-procedure studies will include plain radiographs and MRI. All patients will complete a pretreatment questionnaire.

Patients will be randomized and blinded to the treatment regimen.

Method of randomization: Some of the participating subjects will receive platelet rich plasma and others will receive a saline injection. The platelet rich plasma experimental group will have 50cc of whole blood collected via venipuncture and prepared using the standard PRP protocol.

To blind the control group these patients will have a simulated needle stick and 10 ml (2 teaspoons) of blood will be drawn to test for growth factors. No blood will be given back to the patient. For those in the control group their ligament or tendon will be injected with saline. The staff nurse will place the blood (experimental group) or saline (control group) in syringes and the treating physician and patient will be blinded to the treatment.

Platelet rich plasma injections have an equivalent risk profile to routine injections. Those potential risks include skin discoloration, pain at injection site, superficial or deep infection, no relief of symptoms, worsening of symptoms, and damage to nerve and blood vessels. Potential benefits include significant improvement in symptoms and reduction in time for return to function.

Post injection activity: All patients will be non-weight bearing for 24-48 hours after injection. All patients will have physical therapy two times a week according to a standardized protocol.

Follow up at the clinic for all patients will be every other week from week 1-12. All patients will fill out an injury location specific questionnaire, Tegner Activity Scale, short form-12, and visual analog scale for pain. All radiographic studies will be read by one Stanford radiologist blinded to the study groups.

The endpoint for all patients in the study will be twelve weeks.
