The Physical Toll - Numbers Tell the Story
Catchers receive approximately 120-150 pitches per game, repeatedly squatting and standing each time. Including batting practice and bullpen sessions, daily squat counts can exceed 300. The cumulative knee load across a 143-game season is enormous. Additionally, foul tip impacts, home plate collisions, and throwing motions for stolen base attempts subject the entire body to shock. Catchers are called 'the most physically demanding position,' yet protection and compensation systems proportionate to this burden remain inadequate.
Great Catchers Whose Knees Were Destroyed
NPB history is filled with great catchers whose careers were shortened by knee injuries. Kenji Johjima's knee problems worsened after his MLB stint, and he never regained full performance after returning to NPB. Atsuya Furuta played through knee pain in his final years. Motonobu Tanishige's 27-year career accumulated immeasurable knee damage. These players accepted knee injuries as 'a catcher's fate,' but this is fundamentally a problem organizations should prevent and mitigate.

Post-Retirement Aftereffects - Unspoken Suffering
Catcher knee problems don't end with retirement. Many former catchers develop degenerative knee arthritis affecting daily life. Cases of difficulty climbing stairs or inability to walk long distances in their 40s-50s have been reported. However, NPB has no comprehensive system supporting retired player health management. Compensation for disabilities caused by career overuse is also insufficient. The perception that 'professional baseball players are well-paid' diminishes social concern for post-retirement health issues.
Prevention and Protection Efforts
Efforts to protect catchers' knees are gradually advancing, including research on knee-friendly catching techniques, improved protective gear, and ensuring adequate rest between games. MLB increasingly limits catcher game appearances, with more teams adopting policies of 'no more than five games per week behind the plate.' While awareness of catcher workload reduction is growing in NPB, the traditional value that 'the starting catcher should play every game' remains deeply rooted. Recognition that protecting catcher health serves the long-term interests of all baseball needs to spread.
