Descriptive epidemiology study evaluates performance outcomes in MLB pitchers post revision UCL surgery, suggesting decreased RTP rates.

The aim is to evaluate return to performance in MLB pitchers following revision ulnar collateral ligament reconstruction.
Descriptive epidemiology study of 61 MLB pitchers who underwent revision UCL reconstruction from 2014 to 2024.
Return-to-play analysis compared to 129 pitchers who underwent primary UCL surgery; additional performance analysis on 20 pitchers post-surgery.
Statistical tests including paired and unpaired t tests and penalized likelihood logistic regression were conducted for comparative metrics.
Only 63.2% of MLB pitchers returned to play after revision UCLR.
14.3% achieved pre-revision performance levels in terms of FanGraphs wins above replacement (fWAR) three seasons post-surgery.
Performance metrics such as fastball velocity and Stuff+ showed significant declines after revision compared to primary UCL surgery.
