Little is known about pitching performance or lack of it among Major League Baseball (MLB) pitchers who undergo operative treatment of rotator cuff tears.
To assess pitching performance outcomes in MLB players who needed operative treatment of rotator cuff tears and to compare performance in these athletes with that in a control group of MLB players.
Case-control study.
Publicly available player profiles, press releases, and team injury reports.
Thirty-three MLB pitchers with documented surgery to treat rotator cuff tears and 117 control pitchers who did not have documented rotator cuff tears were identified.
MAIN OUTCOME MEASURE(S): Major League Baseball pitching attrition and performance variables.
Players who underwent rotator cuff surgery were no more likely not to play than control players. Performance variables of players who underwent surgery improved after surgery but never returned to baseline preoperative status. Players who needed rotator cuff surgery typically were more experienced and had better earned run averages than control players.
Pitchers who had symptomatic rotator cuff tears that necessitated operative treatment tended to decline gradually in performance leading up to their operations and to improve gradually over the next 3 seasons. In contrast to what we expected, they did not have a greater attrition rate than their control counterparts; however, their performances did not return to preoperative levels over the course of the study.
对于接受肩袖撕裂手术治疗的美国职棒大联盟(MLB)投手来说,他们的投球表现或缺乏投球表现的情况知之甚少。
评估需要手术治疗肩袖撕裂的 MLB 球员的投球表现结果,并将这些运动员的表现与 MLB 对照组球员的表现进行比较。
病例对照研究。
公开的球员资料、新闻稿和球队伤病报告。
确定了 33 名接受肩袖撕裂手术治疗的 MLB 投手和 117 名未接受肩袖撕裂手术治疗的对照组投手。
美国职棒大联盟投球淘汰率和表现变量。
接受肩袖手术的球员与对照组球员相比,不参加比赛的可能性没有增加。接受手术的球员的表现变量在手术后有所改善,但从未恢复到术前基线状态。需要接受肩袖手术的球员通常比对照组球员更有经验,且平均自责分率(earned run average,ERA)更高。
需要手术治疗肩袖撕裂的投手在手术前的表现逐渐下降,在接下来的 3 个赛季中逐渐改善。与我们预期的相反,他们的淘汰率并不高于对照组;然而,在研究过程中,他们的表现并没有恢复到术前水平。
