Bone bruises (BBs) can provide insight into the biomechanical injury mechanism.PURPOSE/HYPOTHESISThe purpose of this study was to compare BB patterns and concomitant injuries after noncontact ACL tears between pivoting sports athletes and alpine skiers. It was hypothesized that pivoting sports athletes would have a higher prevalence and depth of BBs and a higher prevalence of concomitant injuries.STUDY DESIGNCohort study; Level of evidence, 3.METHODSA total of 446 consecutive patients with ACL injuries between December 2016 and November 2020 were retrospectively analyzed. Patients with contact injuries, an injury mechanism other than alpine skiing or pivoting sports, missing magnetic resonance imaging, failed previous nonoperative treatment, open physes, or incomplete ACL tears were excluded. Magnetic resonance imaging was used to classify BB location and depth as well as concomitant meniscal and collateral ligament injuries. There were 2 groups (alpine skiers vs pivoting sports athletes) that were propensity score matched for age, body mass index, and sex. Chi-square and Mann-Whitney U tests were used to detect differences, with significance set at P < .05. The Fleiss kappa (κ) was used to assess observer agreement.RESULTSPropensity score matching of 122 included patients resulted in 27 patients per group. Pivoting sports athletes showed a higher prevalence of BBs in the lateral femoral condyle than alpine skiers (85.2% vs 51.9%, respectively; P = .008). No significant differences were found for BB prevalence in other anatomic locations, BB depth, and concomitant meniscal and collateral ligament injuries. Post hoc power analysis showed a power of 75%. Observer agreement was almost perfect for BB prevalence (κ = 0.95-1.00), substantial for BB depth (κ = 0.68-0.75), and substantial to almost perfect for concomitant injuries (κ = 0.64-0.94).CONCLUSIONThe prevalence of BBs in the lateral femoral condyle was higher in pivoting sports athletes than in alpine skiers after acute noncontact ACL tears. This suggests that ACL injuries in pivoting sports are associated with higher lateral compression forces in a pivot-shift mechanism, whereas anterior tibial translation and tibial rotation may be the predominant loading pattern in alpine skiing.","PeriodicalId":517411,"journal":{"name":"The American Journal of Sports Medicine","volume":"31 1","pages":"3635465251332272"},"PeriodicalIF":0.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the differences in each pitcher's arsenal, these pitch-specific metrics provide new potential variables to investigate ulnar collateral ligament (UCL) injury risk.PURPOSETo evaluate the association of several pitch-specific advanced analytic and pitch-tracking metrics on UCL surgery rates in Major League Baseball (MLB) pitchers.STUDY DESIGNCase-control study; Level of evidence, 3.METHODSWe performed a retrospective case-control study on all MLB pitchers who underwent primary UCL reconstruction or repair from April 2018 to November 2023. Exclusion criteria included pitchers without 2 qualifying seasons of preoperative pitch-tracking data or who previously underwent UCL surgery. Matched controls were identified in a 2:1 manner by using season, age, position, handedness, and pitch count as covariates. Pitch-specific advanced analytic and pitch-tracking metrics used commonly in the evaluation of MLB players were collected from public web sources sponsored by MLB. Statistical analysis consisted of unpaired t tests comparing preinjury metrics between the case and control groups, along with binary logistic regression.RESULTSA total of 115 MLB pitchers who underwent UCL reconstruction or repair were compared with 230 matched controls. Increased velocity for fastballs, changeups, and sinkers were all associated with UCL surgery. A decreased horizontal release point for fastballs, curveballs, and sinkers were also associated with UCL surgery, along with an increased horizontal approach angle above average for fastballs and sinkers. An increased spin rate for sliders and an increased release extension for cutters were also associated with surgery. Large statistically significant differences in Pitching+ and Location+ for fastballs, changeups, and sinkers, and in Stuff+ for changeups, were associated with surgery. There were no differences in pitch-specific pitch count, active spin, spin axis, vertical release point or approach angle, or overall pitch movement between cases and controls. Binary logistic regression showed that higher velocity fastballs, sliders, and changeups were all associated with UCL surgery, along with sliders with a higher spin rate and cutters with a longer release extension.CONCLUSIONThis study demonstrated that pitch-specific associations with UCL surgery exist compared with matched controls. Specifically, higher velocity fastballs, sliders, and changeups were all associated with UCL surgery, along with sliders with a higher spin rate and cutters with a longer release extension. Fastballs, changeups, and sinkers with superior ability (Pitching+) and command (Location+) were also associated with UCL surgery.

Case series studies have demonstrated that combined slope-reducing tibial osteotomy can greatly improve knee functional scores and stability in revision ACLR. However, there is currently no comparative study evaluating the clinical benefits of osteotomy procedures in primary ACLR. Purpose: To assess the feasibility of combined slope-reducing tibial osteotomy and primary ACLR in patients with a steep PTS and excessive ASLC and to explore the suitable threshold for osteotomy. Study Design: Case series; Level of evidence, 4. Methods: Between 2016 and 2022, of the 108 patients with ACL injuries who had a steep PTS (≥15°) and a follow-up ≥2 years, 30 patients with excessive ASLC (≥6 mm) underwent concomitant slope-reducing tibial osteotomy and ACLR (osteotomy group), and 78 patients underwent isolated ACLR (control group). Propensity score matching at a 1:2 ratio was used to match preoperative variables between the 2 groups. After matching preoperative variables, 25 and 48 patients underwent combined surgery and isolated ACLR, respectively. The primary outcome was ACL graft status (failure and laxity rates). The secondary outcomes were ASLC and anterior tibial subluxation of the medial compartment (ASMC), KT-1000 arthrometer side-to-side difference (SSD), pivot-shift grade, and second-look arthroscopic findings. Stratified analysis was performed with 1° PTS increments to explore the osteotomy threshold. Results: Both groups were comparable in terms of age, sex, side, body mass index, PTS, graft diameter, time from injury to surgery, ASLC, ASMC, KT-1000 arthrometer SSD, pivot-shift grade, and meniscal injuries (all &lt;jats:italic&gt;P&lt;/jats:italic&gt; &gt; .05). The mean PTS significantly decreased from 18.2° to 6.7° ( &lt;jats:italic&gt;P&lt;/jats:italic&gt; &lt; .001) in the osteotomy group. The 2-year rate of ACL graft laxity was 12.0% in the osteotomy group and 35.4% in the control group, with a statistically significant difference ( &lt;jats:italic&gt;P&lt;/jats:italic&gt; = .033).

Exclusion criteria included previous ligamentous knee trauma/surgery, >30 days between injury and MRI, and partial sMCL tears. MRI scans were assessed by 3 independent raters using a predefined sMCL tear location system: type I (proximal 25%), type Ib (proximal femoral bony avulsion), type II (midsubstance, 25%-75%), type III (distal 25%), type IIIb (distal tibial bony avulsion), and type IIIs (Stener-like lesion).

Currently, there is little research that describes the frequency or source of this contact in American football and what scenarios are responsible for these injuries across different player positions.PURPOSETo identify injury scenarios of ankle sprains that result from EE mechanisms in the National Football League (NFL).STUDY DESIGNDescriptive epidemiology study.METHODSAnkle sprains reported during NFL games over 4 consecutive seasons (2017-2020) were identified through a query of the NFL Electronic Medical Record by an independent epidemiological company based on a set of clinical impression codes. Injuries with available video to view the injury enabled the identification of ankle sprains that resulted from EE mechanisms. Standardized terminology was developed to systematically describe and categorize each injury.RESULTSA total of 257 ankle sprains resulting from EE mechanisms were identified from a review of 670 ankle sprains and grouped into 8 standardized injury scenarios. Direct contact to the injured player's foot, ankle, or leg from a large external mass, such as an opponent's pelvis, accounted for 79% of reviewed injuries. Direct contact from a large external mass was the most common scenario for all positions except safeties, and 83% of running back injuries were the result of a tackle. Only 15% of injuries reviewed resulted from injury scenarios in which injurious loading was transmitted solely through the cleat-surface interaction. Safeties and cornerbacks were more commonly involved in these nondirect injury scenarios, such as change of direction, where current interventions may prove more effective.CONCLUSIONEE ankle sprains were observed to occur from 8 different injury scenarios that varied by player position. Interventions through training, bracing, or changing cleat-surface interaction may not be effective for all injury scenarios. Tackling technique may be a unique intervention for running backs.","PeriodicalId":517411,"journal":{"name":"The American Journal of Sports Medicine","volume":"14 1","pages":"3635465251329181"},"PeriodicalIF":0.0,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improving our understanding of the situations and biomechanics that result in an ACL injury in basketball players may support the design of more effective programs to mitigate the injury risk. Purpose: To describe the injury mechanisms, situational patterns, and biomechanics of ACL injuries during matches in professional female basketball players. Study Design: Case series; Level of evidence, 4. Methods: A total of 105 ACL injuries in professional female European basketball leagues from the 2018 to 2023 seasons were identified. There were 41 (39%) injury videos analyzed for injury mechanisms and situational patterns, while biomechanical analysis was possible in 33 cases. There were 3 independent reviewers who rated each video. Data according to player position, phase of the match, and location on the court were also evaluated (n = 41). Analysis regarding neurocognitive perturbation was assessed in 41 cases (100%). Results: Most injuries (n = 28 [68%]) occurred during offensive possession. Indirect contact injuries were more prevalent (n = 23 [56%]) than noncontact injuries (n = 18 [44%]). Overall, 3 main situational patterns constituted 95% of injuries: offensive cut (n = 20 [49%]), defensive cut (n = 12 [29%]), and landing from a jump (n = 7 [17%]). Injuries involving a knee-dominant pattern with valgus were identified in 64% of cases. Injuries were evenly distributed between the first (53%) and second (47%) halves of a game. Half (50%) occurred within the first 10 minutes of effective playing time, and the most frequent months of injury were October and November (44%; early season). Nearly half (46%) of the injuries occurred in small forwards, with 59% of injuries occurring in zone 5. Neurocognitive errors were seen in 56% of injuries, while 92% of defensive injuries showed signs of neurocognitive errors. Conclusion: ACL injuries in professional female basketball players were caused by indirect contact or noncontact, involving offensive and defensive cuts as well as landing from a jump. Biomechanical analysis confirmed a multiplanar mechanism with a knee-dominant pattern and valgus. Most injuries occurred early in the season and within the first 20 effective minutes played (89%), making accumulated fatigue an unlikely risk factor for ACL injuries in basketball players.","PeriodicalId":517411,"journal":{"name":"The American Journal of Sports Medicine","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143790133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
