Approved Clinical Trials
Recover® Platelet Separation Kit
The following research studies have been approved to determine the safety and effectiveness of concentrated platelets prepared by using the Recover® Platelet Separation Kit in patients with chronic tennis elbow (lateral epicondylitis) and chronic foot pain (plantar fasciitis). Platelet rich plasma (PRP) contains factors that are important in the healing process. Participants will either receive an injection with or without PRP.
Unlike other traditional treatments for elbow and foot pain, the Recover® Kit technique involves a simple injection performed in the office. Only those patients meeting the pre-defined approved inclusion/exclusion criteria are eligible to volunteer in these studies.
