To (1) characterize hamstring injury (HSI) recurrence rates across the 2009-2010 to 2019-2020 NFL seasons and (2) to identify HSI recurrence risk factors among positions and determine the weekly return to play (RTP) recurrence risk. We hypothesized that older players, skill position players, and players returning to play faster were most at risk.
Public data from the 2009-2010 to 2019-2020 seasons were reviewed to identify HSIs. Player characteristics were collected before and two seasons following injury. A week-by-week analysis of recurrence risk was evaluated with linear and logarithmic trendlines of the best fit.
A total of 2075 HSI were identified with a mean age of 26.2 years (20.0-43.0), BMI of 29.6 (22.7-43.5), and 3.4 seasons of experience (0-17), with 1826 strains (88.0%), 236 partial tears (11.3%), and 13 complete tears (0.63%). Of the 2075 injuries, 796 (38.4%) were recurrent, with 247 (11.9%) being a same-season reinjury. Logistic regression found that fewer weeks before RTP, in-game injury, and lower BMI were risk factors for same-season recurrence. For any recurrence, logistic regression identified more recent year of injury, lower BMI, and longer playing experience as significant risk factors. Wide receivers were found to be at risk for same-season recurrence. For any-season recurrence, defensive backs, linebackers, running backs, tight ends, and wide receivers were at risk. Week-by-week recurrence analysis determined the greatest risk to be when players returned within 2 weeks (13.4%).
There is a high rate of HSI recurrence in the NFL. Risk factors for same-season injury include shorter time to RTP, in-game injury, lower BMI, and playing wide receiver. Risk factors for any-season recurrence were more recent year of injury, lower BMI, longer playing experience, and playing defensive back, linebacker, running back, tight end, or wide receiver. The greatest risk factor for HSI recurrence was RTP within 2 weeks.
（1）描述 2009-2010 赛季至 2019-2020 赛季 NFL 赛季中腘绳肌损伤（HSI）的复发率；（2）确定各位置 HSI 复发的危险因素，并确定每周重返赛场（RTP）的复发风险。我们假设年龄较大的球员、技能位置的球员和更快重返赛场的球员风险最高。
回顾 2009-2010 赛季至 2019-2020 赛季的公共数据，以确定 HSI。收集受伤前后两个赛季的球员特征。采用线性和对数趋势线对复发风险进行每周分析。
共确定 2075 例 HSI，平均年龄 26.2 岁（20.0-43.0），BMI 为 29.6（22.7-43.5），经验 3.4 个赛季（0-17），1826 例为拉伤（88.0%），236 例部分撕裂（11.3%），13 例完全撕裂（0.63%）。在 2075 例损伤中，796 例（38.4%）为复发性损伤，其中 247 例（11.9%）为同赛季再损伤。逻辑回归发现，RTP 前的周数更少、比赛中受伤和 BMI 较低是同赛季复发的危险因素。对于任何复发，逻辑回归均确定了更近的受伤年份、较低的 BMI 和更长的比赛经验是显著的危险因素。外接手被认为有同赛季复发的风险。对于任何赛季的复发，角卫、线卫、跑卫、近端锋和外接手都有风险。每周复发分析确定，球员在 2 周内（13.4%）内复出的风险最大。
NFL 中存在较高的 HSI 复发率。同赛季损伤的危险因素包括 RTP 时间更短、比赛中受伤、BMI 较低和外接手。任何赛季复发的危险因素包括更近的受伤年份、较低的 BMI、更长的比赛经验以及防守后卫、线卫、跑卫、近端锋和外接手。HSI 复发的最大危险因素是 2 周内 RTP。
