Abstract：
UNASSIGNED: While initial reports of surgical repair of ulnar collateral ligament tears are promising, studies detailing post-repair outcomes are lacking. This study explores the effectiveness of ulnar collateral ligament (UCL) repair in returning professional baseball players to their pre-injury level of play. Our hypothesis is that professional baseball players undergoing UCL repair will have successful outcomes and high return to sport rates after surgery.
UNASSIGNED: Publicly available databases were utilized to search for data on professional baseball players who underwent UCL repair from 2016 to 2021. Players undergoing primary UCL repair with an internal brace were included. Amateur players were excluded as were those undergoing revision UCL repair or UCL reconstruction.
UNASSIGNED: Of the 11 pitchers who underwent UCL repair, minor league baseball (MiLB) pitchers returned to the sport at an average of 17.5 months. MiLB pitchers had similar earned run averages (ERAs), games played, innings pitched, and walks plus hits per inning pitched ratios (WHIPs) before and after surgery. Four major league baseball (MLB) pitchers (80%) returned to the sport at 9.55 months. MLB pitchers played fewer games and pitched fewer innings than before the surgery, but their ERAs and WHIPs were similar before and after surgery. Pitch velocity and spin rates after surgery varied based on pitch type. The seven positional players who underwent UCL repair showed no differences in batting or fielding performance before and after surgery.
UNASSIGNED: UCL repair can successfully return both pitchers and positional players at both the MiLB and MLB levels to play at pre-injury performance levels. Repair can be considered as an option for qualifying injuries in players hoping to maximize performance after surgery with minimal recovery time. Level of Evidence: IV.

摘要：
■虽然尺侧副韧带撕裂手术修复的初步报告是有希望的，缺乏详细说明修复后结果的研究。这项研究探讨了尺侧副韧带（UCL）修复在使职业棒球运动员恢复受伤前水平方面的有效性。我们的假设是，接受UCL修复的职业棒球运动员将在手术后获得成功的结果和较高的运动回报率。
■利用公开可用的数据库搜索2016年至2021年接受UCL维修的职业棒球运动员的数据。包括使用内部支架进行主要UCL修复的玩家。业余球员被排除在外，那些正在进行UCL修复或UCL重建的球员也被排除在外。
■在接受UCL修复的11个投手中，小联盟棒球（MiLB）投手平均在17.5个月内重返这项运动。MiLB投手的平均得分（ERA）相似，玩游戏,一局投球，手术前后步行加每局击球率（WHIPs）。四个美国职业棒球大联盟（MLB）投手（80％）在9.55个月时重返这项运动。与手术前相比，美国职业棒球大联盟投手的比赛次数更少，投球次数也更少，但他们的ERA和WHIP在手术前后相似。手术后的俯仰速度和旋转速率根据俯仰类型而变化。接受UCL修复的七名位置球员在手术前后的击球或投篮表现没有差异。
■UCL修复可以成功地使投手和位置球员在MiLB和MLB级别都返回到受伤前的表现水平。对于希望在手术后以最少的恢复时间最大化表现的球员来说，修复可以被视为合格伤害的一种选择。证据等级：IV。
