Bergstein VE, Agarwal AR, Solon LF, Mikula JD, Best MJ, LaPorte DM. Epidemiologic trends in hand injuries in the National Football League from 2009-2010 to 2019-2020. PHYSICIAN SPORTSMED 2024; 52:400-406. [PMID: 37994029 DOI: 10.1080/00913847.2023.2286942] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Accepted: 11/20/2023] [Indexed: 11/24/2023]
Abstract
OBJECTIVES In American football, hand injuries have been shown to negatively impact performance. The purpose of this study is to characterize the prevalence and severity of hand injuries in National Football League (NFL) players. METHODS A public online database was utilized to identify hand injuries in NFL players from 2009-2010 to 2019-2020. The primary outcome was to analyze the overall incidence of hand injuries (including wrist, metacarpus, finger, and thumb), injury type by each aforementioned anatomic location, and player position. Injury severity was evaluated based on percentage of injuries in which players returned to play (RTP), number of games missed before RTP, and the percentage of injuries resulting in the player being placed on injured reserve (IR). RESULTS Of the 6,127 players included, 847 (13.8%) players sustained a hand injury, of which 24.8%, 34.3%, 17.9%, and 22.9% occurred at the wrist, metacarpus, finger, and thumb, respectively. Of the injured players, 97.4% returned to play following their injury, 14.8% were put on IR, and an average of 1.7 (SD 3.3) games were missed. Quarterbacks were the most likely to sustain hand injuries at all anatomic locations. Wrist injuries were associated with the lowest RTP rate (93.3%), the most players placed on injured reserve (28.6%), and the greatest number of games missed (mean 2.5, SD 4.2). CONCLUSION Hand injuries decreased in prevalence by 65.6% over the 11 NFL seasons evaluated. This trend coincides with the implementation of several safety rules that relate to components of play involving the hands. Quarterbacks experienced the greatest prevalence and severity for all hand injuries. Wrist injuries represent the anatomic location associated with the greatest severity. These findings may be able to inform tailored injury prevention practices by position, and advocate for the further adoption of safety rules to protect players from further injury.

Abstract
The management of any injury in elite athletes poses unique challenges distinct from the general population because the goal is rapid recovery and return to play (RTP) while simultaneously managing residual symptoms and minimizing risk of reinjury. The time required for treatment, recovery, and return to peak performance can have consequences for both the athlete and his or her team: financial implications, psychological stressors, team dynamics, and future performance. RTP after an injury in the professional athlete requires a complex decision-making process with many stakeholders. Several factors influence this decision, not the least of which is the type and mechanism of injury. This article provides an overview of the RTP process including nonmedical factors that may influence this decision, common injuries seen in professional athletes, injury patterns particular to certain popular sports, and imaging guidelines for such injuries.

Abstract
STUDY DESIGN Prospective cross-sectional survey. OBJECTIVE To identify timelines for when athletes may be considered safe to return to varying athletic activities after sustaining cervical spine fractures. BACKGROUND While acute management and detection of cervical spine fractures have been areas of comprehensive investigation, insight into timelines for when athletes may return to different athletic activities after sustaining such fractures is limited. METHODS A web-based survey was administered to members of the Association for Collaborative Spine Research that consisted of surgeon demographic information and questions asking when athletes (recreational vs elite) with one of 8 cervical fractures would be allowed to return to play noncontact, contact, and collision sports treated nonoperatively or operatively. The third part queried whether the decision to return to sports was influenced by the type of fixation or the presence of radiculopathy. RESULTS Thirty-three responses were included for analysis. For all 8 cervical spine fractures treated nonoperatively and operatively, significantly longer times to return to sports for athletes playing contact or collision sports compared with recreational and elite athletes playing noncontact sports, respectively (P< 0.05), were felt to be more appropriate. Comparing collision sports with contact sports for recreational and elite athletes, similar times for return to sports for nearly all fractures treated nonoperatively or operatively were noted. In the setting of associated radiculopathy, the most common responses for safe return to play were "when only motor deficits resolve completely" and "when both motor and sensory deficits resolve completely." CONCLUSIONS In this survey of spine surgeons from the Association for Collaborative Spine Research, reasonable timeframes for return to play for athletes with 8 different cervical spine fractures treated nonoperatively or operatively varied based on fracture subtype and level of sporting physicality.

Abstract
OBJECTIVE Despite robust research endeavors exploring post-play health implications in former NFL players, the impact of former-player status on long-term cardiovascular health has not yet been elucidated. The purpose of this systematic review is to describe the available research on the cardiovascular health in former NFL players. METHODS Relevant studies were included from the PubMed, Scopus, and Embase databases. Studies were evaluated in accordance with PRISMA guidelines. Two independent reviewers conducted the title/abstract screenings and risk of bias determinations. The results of the studies were extracted for inclusion in the review. RESULTS Sixteen studies met inclusion criteria. Though evidence was discordant among studies, former NFL players appeared to possess more favorable metabolic profiles and decreased mortality compared to community controls. Of note, 90% of former players were found to be overweight or obese. CONCLUSION Though cardiovascular disease is the leading cause of death among former NFL players, they possess comparable metabolic and cardiovascular profiles to community controls. Further research is necessary to ascertain the impact of NFL play on cardiovascular health and develop tailored preventative care strategies for former players.

Abstract
OBJECTIVES The stressors that National Football League (NFL) athletes face are well-described and documented with regard to multisystem afflictions and injury prevalence. However, the majority of literature discusses the short-term effects rather than long-term outcomes of playing professional football. The purpose of this study was to characterize the long-term musculoskeletal issues in the retired NFL population. METHODS Publications from CENTRAL, Scopus, Medline, PubMed, Embase, and Google Scholar were searched from database inception to February 2021. A total of 9 cohort studies evaluating lower extremity arthritis in retired NFL athletes were included for review. Two reviewers extracted data from the individual studies, including demographic information (age, body mass index, length of career, position), injury descriptions (location of injury, number of injuries, diagnoses), and procedure (total knee and or hip arthroplasty) frequency. RESULTS Arthritis in retired NFL players was more than twice as prevalent than the general United States male population (95% CI: 2.1-2.3). Ankle osteoarthritis was directly correlated with the number of foot and ankle injuries. Players <50 years of age had a 16.1 and 13.8 times higher risk of undergoing TKA and THA, respectively, when compared to the general population. In older age groups, this trend held with retired NFL players being at least 4.3 and 4.6 times more likely than members of the general population to undergo TKA and THA, respectively. CONCLUSION This review demonstrates that the effects of NFL-related lower extremity injuries extend beyond the players' careers and present a higher risk for early-onset osteoarthritis and overall frequency of undergoing total knee and hip arthroplasty.

Abstract
BACKGROUND Neck injury is a common and often debilitating injury among athletes participating in American football. Limited data exists regarding neck injuries among elite athletes in the National Football League (NFL). To characterize the epidemiology of non-season ending, season-ending, and career-ending neck injuries in the NFL from 2016 through 2021. METHODS Athletes who sustained neck injuries were identified using the NFL's injured reserve (IR) list between the 2016 and 2021 seasons. Demographics and return to sport (RTS) data were collected. Available game footages were reviewed to identify the mechanism of injury (MOI). Injury incidence rates were calculated based on per team play basis. RESULTS During the 6-year study period, 464 players (mean age 26.8 ± 3.2 years) were placed on the injury reserve list due to neck injuries. There were 285 defensive players and 179 offensive players injured (61.4 vs 38.6%, respectively, p < 0.001). Defensive back was the most common position to sustain a neck injury (111 players, 23.9%). 407 players (87.7%) sustained non-season-ending injuries with a mean RTS at 9.2 ± 11.3 days. 36 players (7.8%) sustained season-ending injuries with a mean RTS at 378.6 ± 162.0 days. 21 players (4.5%) sustained career-ending injuries. The overall incidence of neck injuries was 23.5 per 10,000 team plays. The incidence of season-ending injuries and career-ending injuries were 1.82 and 1.06 per 10,000 team plays, respectively. There were 38 injuries with available footages for MOI assessment (23 non-season-ending, 9 season-ending, 6 career-ending). Head-to-head contact was seen in 15 injuries (39.5%), head-down tackling in 11 injuries (28.9%), direct extremity-to-head contact in 7 injuries (18.4%), and head-to-ground contact in 5 injuries (13.2%). There was no significant difference in age, position, or MOI among players sustaining non-season-ending, season-ending, and career-ending injuries. CONCLUSION There is a high incidence of neck injuries among NFL athletes with predictable MOIs including head-to-head contact, head-down tackling, direct extremity-to-head contact, and head-to-ground contact. Defensive players were more likely to sustain neck injuries compared to offensive players. Defensive back was the most common position to sustain a neck injury. LEVEL OF EVIDENCE III.

Abstract
Importance Parkinsonism and Parkinson disease (PD) are known to result from repetitive head impacts from boxing. Repetitive head impacts from American football may also be associated with increased risk of neurodegenerative pathologies that cause parkinsonism, yet in vivo research on the association between football play and PD is scarce and limited by small samples and equivocal findings. Objective To evaluate the association between football participation and self-reported parkinsonism or PD diagnosis. Design, Setting, and Participants This cross-sectional study leveraged data from the online Fox Insight study. Participants completed online questionnaires and self-reported whether they currently had a diagnosis of Parkinson disease or parkinsonism by a physician or other health care professional. In November 2020, the Boston University Head Impact Exposure Assessment was launched for data collection on repetitive head impacts. Data used for this manuscript were obtained from the Fox Insight database on June 9, 2022. A total of 1875 men who endorsed playing any organized sport were included. Former athletes were divided into those who participated in football (n = 729 [38.9%]) and those who participated in other sports (reference group). Exposures Self-reported participation in football, duration and level of football play, age at first exposure. Main Outcomes and Measures Logistic regression tested associations between PD status and history of football play, duration of football play, highest level played, and age at first exposure, controlling for age, education, history of diabetes or heart disease, body mass index, history of traumatic brain injury with loss of consciousness, and family history of PD. Results In this sample of 1875 men (mean [SD] age, 67.69 [9.84] years) enriched for parkinsonism or PD (n = 1602 [85.4%]), 729 (38.9%) played football (mean [SD] duration, 4.35 [2.91] years). History of playing football was associated with higher odds of having a parkinsonism or PD diagnosis (odds ratio [OR], 1.61; 95% CI, 1.19-2.17). Among the entire sample, longer duration of play was associated with higher odds of having a parkinsonism or PD diagnosis (OR, 1.12; 95% CI, 1.06-1.19). Among football players, longer duration of football play (OR, 1.12; 95% CI, 1.02-1.23) and higher level of play (OR, 2.93; 95% CI, 1.28-6.73) were associated with higher odds of having parkinsonism or PD. Conclusions and Relevance In this cross-sectional study of participants enriched for PD, participation in football was associated with higher odds of having a reported parkinsonism or PD diagnosis.

Abstract
Background There is a lack of published information outlining the use of biologics in National Football League (NFL) athletes and limited data to guide biologic treatment strategies. Purpose To develop a consensus on the use of biologics among NFL team physicians. Study Design Consensus statement. Methods A working group of 6 experts convened a consensus process involving NFL team physicians using validated Delphi methodology. Physicians from 32 NFL teams as well as NFL London were invited to take part. This iterative process was used to define statements on the use of biologics in NFL athletes. A recent scoping review exploring biologics in professional athletes was used to inform the first of 3 rounds of surveys, with statements considered under 7 headings: biologics in general, challenges of treating NFL athletes, terminology/nomenclature, autologous blood products, cell-based therapies, guidance for NFL team physicians, and biologic research in the NFL. In addition to rating agreement, experts were encouraged to propose further items or modifications. Predefined criteria were used to refine item lists after each survey. For a consensus within the final round, defined a priori, items were included in the final information set if a minimum of 75% of respondents agreed and fewer than 10% disagreed. Results Physicians from 26 NFL teams and NFL London responded to the initial invitation to participate in the Delphi process; 88.9% of participating team physicians completed the round 1 survey, with response rates of 87.5% in round 2 and 95.2% in round 3. After 3 rounds, 47 statements reached a consensus. A consensus was achieved that platelet-rich plasma has a positive impact on patellar tendinopathy and on symptoms in early osteoarthritis but not for other indications. NFL team physicians agreed that while cell therapies have the potential to improve symptoms, the misrepresentation of uncharacterized preparations as "stem cells" has contributed to the widespread use of unproven therapies. Conclusion This study established an expert consensus on 47 statements relating to the use of biologics in NFL athletes. In addition to providing clinical guidance for the use of biologics in NFL athletes, this study identified key areas for future focus including the development of athlete education materials.

Abstract
OBJECTIVES The National Football League (NFL) altered the 2020 season due to the COVID-19 pandemic, which resulted in canceled preseason games and a dynamic regular season schedule to accommodate for canceled games. The purpose of this study was to evaluate if the disrupted training and preseason schedule lead to increased injury rates as seen in other professional sports. We hypothesized that the overall injury rate would be higher in the 2020 season compared to the 2018-2019 seasons and that this increase will affect all body regions equally. METHODS Publicly released NFL weekly injury reports were queried to identify players listed as out or placed on the injured reserve for at least one game in the 2018-2020 seasons. Injuries were categorized into upper extremity, lower extremity, spine/core, head, illness, not injury related and undisclosed injuries. Incidents per 1000 athlete exposures were calculated for the prior two seasons (2018-2019) and for the 2020 season separately. Percentage of injuries occurring in each position was calculated separately for the pre-COVID-19 (2018 and 2019) and post-COVID-19 (2020) cohorts. Incidence rate ratios (IRR) and confidence intervals were used to compare injury rates in 2018-2019 versus 2020. The z-test for proportions was used to determine significant differences between injury incidences. RESULTS The overall incidence rate per 1000 athlete exposures in 2020 was not significantly different compared to pre-COVID-19 seasons (21.6 versus 23.1, IRR 0.94, 95% CI: 0.9-1.0 p > 0.999). The proportion of injuries by position did not change before and after COVID-19 either (p > 0.999). Out listings due to illness were significantly increased during the 2020 season (0.8 versus 0.3, IRR 2.8, 95% CI: 1.4-5.2, p = 0.004). CONCLUSION The incidence of NFL injuries did not significantly change in 2020. The distribution of injuries did not change with respect to position.

Abstract
OBJECTIVES Hip and core injuries are common in National Football League (NFL) athletes; however, the impact following injury remains unclear. The goal of this manuscript was to determine the impact of nonoperative hip and core injuries on return to play and performance. METHODS NFL athletes who sustained a hip or core injury treated nonoperatively between 2010 and 2016 were identified. Offensive and defensive power ratings were calculated for each player's injury season and two seasons before and after to assess longitudinal impact. A matched control group without an identified hip and/or core injury was assembled for comparison. RESULTS A total of 41 offensive and 71 defensive players with nonoperative hip or core injury were analyzed. All athletes returned to play; offensive and defensive players missed 4.0 ± 5.2 and 3.1 ± 2.6 games after injury, respectively. Offensive players played fewer cumulative career games returning from core injury versus hip (23.5 ± 20.6 vs 41.0 ± 26.4). Defensive players played fewer games (58.1 ± 41.1 versus 37.4 ± 27.1, p < 0.05) with lower defensive power rating (133.9 ± 128.5 versus 219.8 ± 212.2, p < 0.05) cumulatively after hip or core injury. Additionally, 2 years following injury, defensive players played fewer games compared to controls (9.5 ± 7.0 versus 10.9 ± 6.8, p < 0.05). Following hip injury specifically, NFL defenders played fewer games (39.8 ± 27.9 vs 61.9 ± 38.8; p < 0.05) and had a lower defensive power rating (145.9 ± 131.7 vs 239.0 ± 205.9; p < 0.05) compared to before injury. CONCLUSION Overall, NFL players return to play following nonoperative hip and core injuries. Defensive players played in fewer games following hip or core injury compared to controls; offensive players were unaffected. Hip injuries have a greater impact on performance compared to core injuries in defensive athletes; offensive players played fewer games upon return from core injury.

Abstract
OBJECTIVES COVID-19 altered National Football League (NFL) player and team training during the 2020 offseason. All preseason games were cancelled resulting in absence of game play before the first week of the regular season. Thus, concerns exist regarding injury susceptibility of players during regular season games. The purpose of this study was to evaluate and compare injury rates during the 2020 NFL season versus injury rates from the unaffected 2017-2019 seasons. We hypothesized there would be an increased injury rate and an increased rate of season ending injuries during the modified 2020 season. METHODS The NFL's public injury database was queried to identify players placed on the injury lists throughout the 2017-2020 seasons. All players listed as "out" and on the injured reserve due to physical injury were included in the data set. For further stratification, injury incidence was separated based on position. Time missed due to COVID-19 illness was not included. Injury rates were expressed as injuries per 1000 athlete exposures (AE). RESULTS Overall, 893 individual players missed games due to injury during the 2020 NFL regular season compared to an average of 743 over the 2017-2019 seasons. Defensive players at all positions had a statistically significant increase in injury incidence from an average of 7.54 to 10.20 injuries per 1000 AE. Defensive backs were most affected with a 46% increase in players injured. There was no statistically significant difference in season ending injuries for any position. CONCLUSIONS The COVID-19 stricken 2020 NFL regular season saw an increased rate and incidence of injuries. Specifically, defensive players had a higher incidence of injury overall with defensive backs experiencing the greatest increase in injury rates.

Abstract
PURPOSE American football is considered one of the more injury-prone sports given its high-speed and high-impact nature. While much attention has been focused on chronic traumatic encephalopathy, spinal injuries represent the most common catastrophic injury incurred in football. The goal of this investigation is to describe the most common football-associated spinal lesions in a multi-center health system. METHODS This is a retrospective analysis of patients with imaging evidence of spinal injuries related to American football during a 10-year period. Injuries were classified based on the anatomic level, type injury, spinal cord compromise, and therapeutic management. Chi-squared and Fisher's exact test were used for statistical analysis of categorial variables, and simple logistic regression was used to determine individual odds ratios. RESULTS A total of 71 patients were included, with a median age of 17 (IQR, 15-22) years. The cervical spine was the most frequently affected segment (46%), followed by lumbar spine injuries (45%), and thoracic spine injuries (10%). Discogenic injuries were identified in 45 patients (63%). Spinal cord injury was documented in 7 subjects (10%), while cauda equina compression was reported in 1 patient (1%). CONCLUSIONS Acute spinal injuries continue to represent a significant cause of morbidity among American football players. Compared to national statistics, we found a similar distribution of spinal injuries in terms of anatomic location and an alarmingly high proportion of SCI. This investigation represents the largest single-center study addressing spinal injuries among football players.

Abstract
OBJECTIVE To characterize recurrent instability, return to sport (RTS), and patient-reported outcomes (PROs) after arthroscopic Bankart repair for acute traumatic anterior shoulder instability in National Collegiate Athletic Association (NCAA) and National Football League (NFL) football players. DESIGN Case series. SETTING Orthopaedic and sports medicine clinic. PARTICIPANTS National Collegiate Athletic Association and NFL football athletes with traumatic anterior shoulder instability who underwent arthroscopic shoulder stabilization at a single institution with at least 2-year follow-up. INTERVENTIONS OR ASSESSMENT OF RISK FACTORS OR INDEPENDENT VARIABLES Arthroscopic Bankart repair. MAIN OUTCOME MEASURES Recurrent instability, RTS, patient satisfaction, the visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, and Rowe score. RESULTS Thirty-three players were included with a mean age of 23.8 years (range, 18-33 years) and a mean follow-up of 6.3 years (range, 4.1-9.3 years). One shoulder (3.0%) had a postoperative subluxation event, and 1 shoulder (3.0%) required revision surgery for issues other than instability; 93.3% of players were able to RTS at the same level or higher for at least 1 season. Mean satisfaction was 8.9 ± 2.3. Mean VAS was 1.0 ± 1.7, and mean ASES and Rowe scores were 90.7 ± 18.5 and 89.7 ± 15.2, respectively. CONCLUSION Arthroscopic Bankart repair is an effective surgical intervention for traumatic anterior shoulder instability in NCAA and NFL football players. At a mean 6-year follow-up, surgery restored stability in 97% of cases and 93.3% returned to their preinjury level of sport.

Abstract
BACKGROUND Numerous researchers have leveraged publicly available Internet sources to publish publicly obtained data (POD) studies concerning various orthopaedic injuries in National Football League (NFL) players. PURPOSE To provide a comprehensive systematic review of all POD studies regarding musculoskeletal injuries in NFL athletes and to use anterior cruciate ligament (ACL) injuries in NFL players to quantify the percentage of injuries identified by these studies. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS A systematic review was conducted to identify all published studies utilizing POD regarding ACL injury in NFL athletes from 2000 to 2019. Data regarding player demographics were extracted from each publication. These results were compared with prospectively collected data reported by the teams' medical staff to the NFL Injury Surveillance System database linked to the League's electronic health record. An ACL "capture rate" for each article was calculated by dividing the number of ACL injuries in the POD study by the total number of ACL injuries in the NFL injury database occurring in the study period of interest. RESULTS A total of 42 studies were extracted that met the definition of a POD study: 28 evaluated a variety of injuries and 14 dealt specifically with ACL injuries, with 35 (83%) of the 42 studies published during or since 2015. POD studies captured a mean of 66% (range, 31%-90%) of ACL injuries reported by the teams' medical staff. This inability to capture all injury rates varied by position, with 86% capture of ACL injuries in skill athletes, 72% in midskill athletes, and 61% in linemen. POD studies captured 35% of injuries occurring during special teams play. CONCLUSION The frequency of studies leveraging publicly obtained injury data in NFL players has rapidly increased since 2000. There is significant heterogeneity in the degree to which POD studies correctly identify ACL injuries from public reports. Sports medicine research relying solely on publicly obtained sources should be interpreted with an understanding of their inherent limitations and biases. These studies underreport the true incidence of injuries, with a bias toward capturing injuries in more popular players.

National Football League Wide Receivers and Running Backs Have Decreased Production Following ACL Reconstruction: An Evaluation of Fantasy Football Performance as an Outcome Measure. Arthrosc Sports Med Rehabil 2022; 4:e315-e324.

Abstract
Purpose To use fantasy football points as a simple measure alongside on-field statistics to compare performance in National Football League (NFL) offensive skill position players before and after anterior cruciate ligament (ACL) reconstruction. Methods A retrospective review of all NFL quarterbacks (QB), running backs (RB), wide receivers (WR), and tight ends (TE) who sustained an isolated, unilateral ACL injury from 1988 to 2017 was conducted. Data were collected from public data sources, team releases, NFL injury reports, press releases, and other Internet resources. For each player, a matched control with similar demographics was identified. Their in-game performance post-ACL reconstruction was analyzed using fantasy football points as an outcome measure. Results A total of 13 QBs, 30 RBs, and 29 WRs who underwent ACL reconstruction from 1988 to 2017 and who met inclusion criteria were retrospectively identified and reviewed. Of the 13 quarterbacks included in the study, there was no statistically significant difference in fantasy football points between the pre- and post-ACL reconstruction groups, as well as post-ACL and matched control groups. There was a statistically significant decrease in career fantasy football performance of running backs post-ACL reconstruction compared with matched control groups (129.6 vs 553.6; P < .0001). There was also a statistically significant decrease in per game fantasy football points post-ACL reconstruction (4.4 vs 11.2; P < .0001). Lastly, WRs also demonstrated a decrease in career fantasy football performance post-ACL reconstruction compared with matched controls (145.3 vs 460.9; P = .002). In addition, they also had a decrease in per game fantasy football performance (5.0 vs 7.7; P = .042). Conclusions Quarterbacks did not have a statistically significant decrease in performance following ACL reconstruction based on fantasy football performance. Conversely, both running backs and wide receivers had decreased per game and career performance post-ACL reconstruction based on their fantasy football statistics. Furthermore, RBs had the largest decline in production each season over a 3-year period following ACLR compared to QBs and WRs, respectively. Level of Evidence Level III, case-control study.

Abstract
Background: Considerable variability exists in return-to-play rates after anterior cruciate ligament (ACL) injury and reconstruction (ACLR) among National Football League (NFL) players of different positions. Purpose/Hypothesis: The purpose of this study was to compare return-to-play and performance levels by position in NFL players after ACLR. It was hypothesized that (1) ACL injuries have significant effects on the careers of NFL players, including return to play and performance, and (2) players of certain positions that involve relatively less pivoting and cutting perform better after ACLR. Study Design: Descriptive epidemiology study. Methods: All NFL players who underwent ACLR between 2013 and 2018 were identified using the FantasyData injury database. Player characteristics, snap count, games played, games started, and performance metrics were collected for 3 years before and after injury using the Pro Football Reference database. Performance was measured using an approximate value (AV) algorithm to compare performance across positions and over time. Nonparametric tests were used to compare the pre- and postinjury data and the percentage change in performance between different positions. Results: Overall, 312 NFL players were included in this study, and 174 (55.8%) returned to play. Of the eligible players, only 28.5% (n = 59/207) remained in the league 3 years postinjury. Within the first 3 years postinjury, players played in fewer games (8.7 vs 13.7; P < .0001), started in fewer games (3.0 vs 8.3; P < .0001), had lower AVs (1.5 vs 4.3; P < .0001), and had decreased snap counts (259.0 vs 619.0; P < .0001) compared with preinjury. Quarterbacks were most likely to return to play (92.9% vs 53.7%; P = .0040) and to return to performance (2% vs 50% decrease in AV; P = .0165) compared with the other positions. Running backs had the largest decrease in AV (90.5%), followed by defensive linemen (76.2%) and linebackers (62.5%). Conclusion: The study findings indicated that NFL players are severely affected by ACL injury, with only 28.5% still active in the league 3 years after the injury. Running backs, defensive linemen, and linebackers performed the worst after injury. Quarterbacks were most likely to return to play and had superior postinjury performance compared with the other positions.

Abstract
Background: The impact of fatigue and preseason preparation on anterior cruciate ligament (ACL) tears in the National Football League (NFL) are not well described. The 2020 NFL season did not include the standard preseason in response to changes secondary to the coronavirus disease-2019 (COVID-19) pandemic. Purpose: To evaluate the association of game play on ACL tears in NFL athletes and to determine if differences in ACL tear epidemiology were present based on season of play from 2013 to 2020. Study Design: Descriptive epidemiology study. Methods: ACL tears in NFL athletes were identified using publicly available data. Games played and snap counts at the time of injury were recorded for each athlete sustaining game-related injuries. Tear rates were determined, and injuries were also calculated per 1000 athlete-exposures. Incidence rate ratios (IRRs) with 95% confidence intervals (CIs) were calculated. Results: Overall, 379 ACL tears were identified, including 256 (67.6%) during game play and 118 (31.1%) during practice. Practice-based injuries were significantly higher in the preseason versus the remainder of the season. Games and snaps at the time of injury did not differ by year. The incidence rate of preseason injuries was significantly greater relative to in-season injuries (IRR = 2.68; 95% CI, 2.18-3.29; P < .00001). There was an elevated incidence rate of in-season injuries in 2020 relative to 2014-2019 combined (IRR = 1.49; 95% CI, 0.98-2.19; P = .048). In 2013 to 2019, the most frequent month of injury was the first month of the preseason in August (119/334 tears; 35.6%), whereas in 2020, the most frequent month was September (13/41 tears, 31.7%). The proportion of tears in September 2020 was not different from the proportion of tears in August 2013 to 2019. Conclusion: There was an increased proportion of in-season ACL tears in the 2020 NFL season relative to 2014 to 2019; this is attributable to a frameshift in the consistent trend of injuries in the 1st month to return of competitive play, with 2020 being in the regular season in September as opposed to the preseason in August.

Abstract
BACKGROUND American football players are at increased risk for many forms of spinal injury. Intervertebral disk herniations are particularly concerning as they are the leading cause of days lost to injury and can have long-term effects on player careers. Disk herniation management plays a major role in the likelihood and success of return-to-play (RTP). OBJECTIVE To assess the incidence, demographic variables, treatment approaches, outcomes, and RTP rates of disk herniations in American football players. METHODS A systematic review of the literature investigating disk herniations in American football players using PubMed, Cochrane Library, and Embase was performed. RTP estimates were calculated by pooling study-specific data using a random-effects model. RESULTS Four hundred twenty-two studies were identified, with 18 meeting inclusion criteria. Offensive and defensive linemen were the 2 most commonly injured positions. Players undergoing operations were on average younger, with higher body mass indexes, fewer seasons played, and longer post-treatment careers than nonsurgical counterparts. Postsurgical recovery periods lasted an average 106 d, with a mean RTP duration of 33 games over 2.7 yr and an 8.45% reoperation rate. Operative treatment offered a nonsignificant increase in the likelihood of return-to-play compared with nonoperative treatment (odds ratio = 2.81, 95% CI 0.83-9.51). CONCLUSION Disk herniations are a common injury, with surgery potentially improving post-treatment outcomes. The literature suffers from heterogeneous definitions of RTP and varying performance metrics, making it difficult to draw clear conclusions. To better understand the impact of disk herniation and treatment on player health and performance, more studies should be performed prospectively and with standardized metrics.

Orthop J Sports Med 2021; 9:23259671211003491. [PMID: 34017880 PMCID: PMC8114264 DOI: 10.1177/23259671211003491] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Accepted: 12/14/2020] [Indexed: 11/16/2022] Open
Abstract
Background: Impaired neuromuscular function after concussion has recently been linked to increased risk of lower extremity injuries in athletes. Purpose: To determine if National Football League (NFL) athletes have an increased risk of sustaining an acute, noncontact lower extremity injury in the 90-day period after return to play (RTP) and whether on-field performance differs pre- and postconcussion. Study Design: Cohort study, Level of evidence, 3. Methods: NFL concussions in offensive players from the 2012-2013 to the 2016-2017 seasons were studied. Age, position, injury location/type, RTP, and athlete factors were noted. A 90-day RTP postconcussive period was analyzed for lower extremity injuries. Concussion and injury data were obtained from publicly available sources. Nonconcussed, offensive skill position NFL athletes from the same period were used as a control cohort, with the 2014 season as the reference season. Power rating performance metrics were calculated for ±1, ±2, and ±3 seasons pre- and postconcussion. Conditional logistic regression was used to determine associations between concussion and lower extremity injury as well as the relationship of concussions to on-field performance. Results: In total, 116 concussions were recorded in 108 NFL athletes during the study period. There was no statistically significant difference in the incidence of an acute, noncontact lower extremity injury between concussed and control athletes (8.5% vs 12.8%; P = .143), which correlates with an odds ratio of 0.573 (95% CI, 0.270-1.217). Days (66.4 ± 81.9 days vs 45.1 ± 69.2 days; P = .423) and games missed (3.67 ± 3.0 vs 2.9 ± 2.7 games; P = .470) were similar in concussed athletes and control athletes after a lower extremity injury. No significant changes in power ratings were noted in concussed athletes in the acute period (±1 season to injury) when comparing pre- and postconcussion. Conclusion: Concussed, NFL offensive athletes did not demonstrate increased odds of acute, noncontact, lower extremity injury in a 90-day RTP period when compared with nonconcussed controls. Immediate on-field performance of skill position players did not appear to be affected by concussion.

Abstract
The epidemiology of any given topic sometimes is overlooked. This is true particularly with sports physicians and sports injuries. The identification of sports-specific injury patterns by collection and examination of data can help prevent injuries. Thus, as a physician involved in any sport, it is essential to have this knowledge because understanding it and imparting it may allow a valuable contribution to the health and safety of the athletes and success of the teams.

Abstract
BACKGROUND American Football (AF) players are assigned to positions by specific abilities and responsible for different tasks on the field; this may result into wide differentiation in experienced injuries. The aim of this study was to analyze the causes of injuries and their differentiation depending on the position on the pitch. METHODS Original questionnaire was used to investigate 150 Polish amateur AF players who had suffered from 189 injuries. The questionnaire detailed the following positions: offensive line (OL), defensive line (DL), quarterback (QB), running back (RB), wide receiver (WR), linebacker (LB), defensive backs (DB). The results were statistically analyzed by SofaStas v. 1.4.5 (SOFA Statistics, San Jose, CA, USA) and then had been interpreted. RESULTS Over 90% of all investigated AF players had self-reported injury history with the injury rate 1.27 injury per player. No statistically significant relationship was stated between position on the pitch and the occurrence rate, type and location of the injury. Significant relationship (P=0.030) was stated between the injury circumstances and position on the pitch - QB were mostly injured in collision with opponent, OL in direct sport fight while WR and RB due to a fall. CONCLUSIONS Occurrence and type of injuries in AF players does not depend on position on the pitch in AF. Relationship between the injury location or injury circumstances and position on the pitch requires further studies. The most common location of injury is the knee joint, and the most common type of injury is sprain while the most common causes of injury were collision with opponent and direct sport fight.

Abstract
Background: Athletes in the Women’s National Basketball Association (WNBA) and National Basketball Association (NBA) are subject to high injury rates given the physical demands of the sport. Comprehensive data regarding injury patterns and rates in these athletes are limited. Purpose: To summarize available data on orthopaedic and sports medicine–related injuries through 2020 in professional female and male basketball players. Study Design: Systematic review; Level of evidence, 4. Methods: A search was conducted using PubMed and Embase through April 5, 2020, to identify injury studies regarding WNBA and NBA players. Studies were included if the injury or surgery was considered a direct consequence of game play including musculoskeletal/orthopaedic, concussion, ophthalmologic, and craniomaxillofacial injuries. Systematic reviews, screening studies, or studies without sufficient WNBA or NBA player subgroup analysis were excluded. Results: A total of 49 studies met inclusion criteria, 43 (87.8%) of which detailed musculoskeletal injuries. The lower extremity represented 63.3% of studies. A majority (59.2%) of studies were level 4 evidence. The source of data was primarily comprehensive online search (n = 33; 67.3%), followed by official databases (n = 11; 22.4%). Only 3 studies concerned WNBA athletes compared with 47 that concerned NBA athletes. The lowest return-to-play rates were cited for Achilles tendon repairs (61.0%-79.5%). Variability in return-to-play rates existed among studies even with similar seasons studied. Conclusion: The majority of literature available on orthopaedic and sports medicine–related injuries of NBA and WNBA athletes is on the lower extremity. The injuries that had the greatest effect on return to play and performance were Achilles tendon ruptures and knee cartilage injuries treated using microfracture. The reported outcomes are limited by heterogeneity and overlapping injury studies. There are limited available data on WNBA injuries specifically.

Abstract
As clinicians strive to apply evidence-based principles, team-based practitioners have identified a large gap as it relates to published research, ideal applications of evidence-based practice, and actual clinical practice related to injury prevention in elite sport within the United States. For rehabilitation professionals, especially those intimately involved in the research of injury prevention, the solution often seems quite clear and defined. However, preventing injury by implementing the latest recommendation from the most recent prospective study on the using the FIFA 11 + warm-up, a Copenhagen Adduction exercise, or a plyometric drill with elite athletes may not be as effective as was seen among the cohort used in the study. In addition to extrapolating research, clinicians face additional challenges such as variance among professions, schedule density, and off-season contacts with athletes. There is an inherent difficulty in the application of research to practice in elite sport as it relies on the teamwork of not only the practitioner and athlete, but the entire sporting organizational structure and those involved in athlete participation. The purpose of this clinical commentary is to explore the difficulty with application of research in clinical practice and to discuss potential strategies for improving carry over from research to clinical practice.

Abstract
Background Orthopedic injuries of National Hockey League (NHL) players are common and may significantly affect players’ health and careers. Evidence-based injury management is important in guiding players’ timely return to sport and their ability to play at their pre-injury levels of competition. Purpose To summarize all data published between January 1980 and March 2020 on orthopedic injuries experienced by professional ice hockey players competing in the NHL. Study Design Systematic review. Methods A literature review of studies examining orthopedic injuries in the NHL was performed using the Embase, PubMed, and CINAHL databases. The review included studies focusing on NHL players and players attending the NHL Combine and preseason NHL team camps. Studies pertaining to non-orthopedic injuries and case reports were excluded. Results A total of 39 articles met the inclusion criteria and were analyzed. The articles were divided by anatomic site of injury for further analysis: hip and pelvis (24%), general/other (14%), ankle (10%), knee (10%), foot (7%), shoulder (7%), thigh (7%), trunk (7%), spine (6%), elbow (4%), and hand and wrist (4%). The majority of articles were Level IV Evidence (51.3%), followed by Level III Evidence (38.5%). Most studies obtained data from publicly available internet resources (24.7%), player medical records (19.5%) or surveys of team physicians and athletic trainers (15.5%). A much smaller number of studies utilized the NHL Injury Surveillance System (NHLISS) (6.5%) or the Athlete Health Management System (AHMS) (2.6%). Conclusion This systematic review provides NHL team physicians with a single source of the current literature regarding orthopedic injuries in NHL players. Most research was published on hip and pelvis (24%) injuries, did not utilize the NHLISS and consisted of Level IV Evidence.

Abstract
BACKGROUND Professional athletes are at increased risk of injury with high activity levels and additional pressure to return to sports quickly after anterior cruciate ligament (ACL) injury. The purpose of this study was to determine ACL graft re-tear rates in National Basketball Association (NBA), Major League Baseball (MLB), and National Hockey League (NHL) athletes using publicly available databases and to compare these to general populations, National Football League (NFL) athletes, and the pediatric population to establish a baseline for those partaking in high-risk sporting activity. METHODS A comprehensive online search was performed to identify athletes in the NBA, MLB, and NHL who had a reported ACL tear between 2007 and 2017. For each tear, the type of tear (initial or re-tear) and return to play data were documented. Comparisons of re-tear rates from these leagues to prior registry, meta-analyses, and epidemiologic studies were performed using Fisher's exact or Chi-squared tests. RESULTS The aggregate re-tear rate was 11.9%. ACL re-tear rates by league did not statistically differ. Return to play rate after index surgery was 95.8%, whereas after a revision procedure was 92.3%. There was a statistically significant difference between the studied ACL re-tear rates (NBA, MLB, NHL) and those of national registries (P < 0.01), and no difference when compared with the pediatric population or with the NFL. CONCLUSIONS Exposure to higher-risk sporting activity, common to pediatric patients and professional athletes, is a likely major influential factor in ACL re-tear.

Abstract
Abstract
BACKGROUND
Previous studies have attempted to establish return-to-play (RTP) guidelines in collision sport athletes after cervical spine injury; however, recommendations have been limited by scant high-quality evidence and basic consensus survey methodologies.
OBJECTIVE
To create relevant clinical statements regarding management in collision sport athletes after cervical spine injury, and establish consensus RTP recommendations.
METHODS
Following the modified Delphi methodology, a 3 round survey study was conducted with spine surgeons from the Cervical Spine Research Society and National Football League team physicians in order to establish consensus guidelines and develop recommendations for cervical spine injury management in collision sport athletes.
RESULTS
Our study showed strong consensus that asymptomatic athletes without increased magnetic resonance imaging (MRI) T2-signal changes following 1-/2- level anterior cervical discectomy and fusion (ACDF) may RTP, but not after 3-level ACDF (84.4%). Although allowed RTP after 1-/2-level ACDF was noted in various scenarios, the decision was contentious. No consensus RTP for collision athletes after 2-level ACDF was noted. Strong consensus was achieved for RTP in asymptomatic athletes without increased signal changes and spinal canal diameter >10 mm (90.5%), as well as those with resolved MRI signal changes and diameter >13 mm (81.3%). No consensus was achieved in RTP for cases with pseudarthrosis following ACDF. Strong consensus supported a screening MRI before sport participation in athletes with a history of cervical spine injury (78.9%).
CONCLUSION
This study provides modified Delphi process consensus statements regarding cervical spine injury management in collision sport athletes from leading experts in spine surgery, sports injuries, and cervical trauma. Future research should aim to elucidate optimal timelines for RTP, as well as focus on prevention of injuries.
