I posted a meta-analysis showing PRP doesn't beat saline for tennis elbow. The regenerative medicine community came for me, hard. This episode walks through the incident, what the evidence states, why the comparator you choose determines the conclusion you reach, and what the pushback reveals about incentives in musculoskeletal medicine.
