Chronic tendon injury can cause notable impact to a patient’s physical function. Regenerative platelet rich plasma (PRP) injections have been utilized to treat a multitude of chronic musculoskeletal tendon injuries over the years, with generally positive results. To date, there have been no case reports of platelet rich plasma injections to the finger extensor tendons or collateral ligaments. Our case reviews the clinical course and outcome experienced by a 32-yearold Asian American male suffering from chronic right middle finger pain and sensitivity near the proximal interphalangeal (PIP) joint resulting from sequelae of prior laceration injury. Despite intense efforts with occupational therapy, the patient’s pain failed to resolve after two years. A single PRP injection under ultrasound guidance was trialed, and subsequent to treatment, the patient’s pain and range of motion improved, albeit by a small margin. Platelet-rich plasma injections may be considered as an adjunct to standard rehabilitation measures for finger soft tissue injury, particularly in outpatient physical medicine and rehabilitation or pain medicine clinic settings; however, more research is needed to validate results experienced by this single patient.
