Review Question - QID 220067

A 37-year-old oil field worker presents to the clinic for a follow-up of his right lateral epicondylitis. He has a history of left lateral epicondylitis that failed nonoperative treatment, including steroid injection, and underwent left open extensor carpi radialis brevis (ECRB) debridement and release. He is nervous that the right side will require surgical intervention as well. Given his persistent symptoms despite activity modification, he undergoes a platelet-rich plasma (PRP) injection at the lateral epicondyle through the common extensor origin. What is the expected outcome of this patient compared to his prior contralateral injection?
