“…PURPOSE: To determine the (1) return-to-sport (RTS) rate in MLB players after hip arthroscopic surgery for FAI; (2) postoperative career length, innings pitched (IP) (pitchers), and plate appearances (PA) (position players); (3) preoperative and postoperative performance; and (4) postoperative performance compared with control players matched by position, age, years of experience, and performance. …”

“…For 20 pitchers who returned to pitch, MLB pitching metrics of earned run average (ERA), walks plus hits per innings pitched (WHIP), wins above replacement (WAR), strikeouts per nine innings (K/9), average fastball velocity, and strike percentage, were used to assess a pitcher’s ability to return to preoperative performance level. …”

“…HYPOTHESIS: There is a high rate of RTS in professional baseball pitchers following LD/TM tears with no significant difference in rate of RTS or performance, specifically related to the primary outcome performance variables of earned run average (ERA), WHIP ((walks +hits)/innings pitched), fielding independent pitching (FIP), and wins above replacement (WAR)) between cases and controls for both operative and non-operative treatment. …”
