Meniscal Injuries Are Decreasing but Are Increasingly Being Treated Surgically With Excellent Return to Play Rates in Professional Baseball Players

Abstract

The purposes of this study were to determine the incidence and key characteristics of meniscus injuries in professional baseball players, assess current treatment strategies, determine the return to play rates at any level (RTP) and at the same level (RSL), and identify prognostic factors that predict injury severity. After approval from the Major League Baseball (MLB) Research Committee and our institutional review board, the MLB Health and Injury Tracking System was used to identify meniscus injuries occurring across MLB and Minor League Baseball (MiLB) from 2011 to 2017. Analyzed injuries occurred during normal baseball activity in a player who was active on an MLB or MiLB roster and resulted in at least 1 day missed. A total of 293 professional baseball players sustained 314 meniscus injuries from 2011 to 2017 (7 years) for a mean of 44.9 injuries/y. Pitchers were the most injured position (31.8%), followed by infielders (26.4%). Catchers and infielders missed the most median number of days (50 days). When comparing injuries to landing leg vs push-off leg in pitchers, injury to the push-off leg resulted in significantly more days missed per injury compared to the lead leg (59.6 vs 39.9 days, P= .048). Overall, RTP was 93.0%, while RSL was 84.4%. Over 7 professional baseball seasons, 314 meniscus injuries occurred in 293 players. Pitchers and catchers were most injured, and overall, the number of meniscal injuries per year declined while the percentage of injuries that required surgery increased over time. High rates of RTP were observed. Level IV, therapeutic case series.
