Abstract
PURPOSE Resistance to fatigue is a key factor in injury prevention that needs to be considered in return-to-sport (RTS) scenarios, especially after severe knee ligament injuries. Fatigue should be induced under game-like conditions. The SpeedCourt (SC) is a movement platform for assessing multidirectional sprint performance, typical of game-sports, due to change-of-direction movements in response to a visual stimulus. Designing adequate fatigue protocols requires the suitable arrangement of several loading variables such as number of intervals, sprint distance or work/relief ratio (W:R). Therefore, this study analysed the acute fatigue effects of different SC protocols on metabolic load, cognitive function and neuromuscular performance. METHODS Eighteen female soccer players (mean ± SD; age: 23.1 ± 4.6 years) of the 1st German Division participated in this randomised, crossover study. Using a random allocation sequence, players completed four volume-equated protocols differing in W:R and sprint distance per interval (P1:12 × 30 m, W:R = 1:2 s; P2:12 × 30 m, W:R = 1:3 s; P3:18 × 20 m, W:R = 1:2 s; P4:18 × 20 m, W:R = 1:3 s). Pre- and post-exercise, metabolic load was measured per blood lactate concentration (BLaC), cognitive function per reaction time (RT), and neuromuscular performance including multiple rebound jumps (MRJ height, primary outcome variable; Reactive Strength Index, RSI) and 5 m sprint times (SP5). RESULTS Repeated-measures ANOVA revealed significant main time effects (p < .05) with improved performance post-exercise in RT (504 vs. 482 ms, d = 1.95), MRJ height (24.0 vs. 24.8 cm, d = 0.77), RSI (1.39 vs. 1.43, d = 0.52), and SP5 (1.19 vs. 1.17 s, d = 0.56). There was significant main time (p < .001) and time x protocol interaction effects in BLaC (p < .001). P1 induced higher BLaC values (4.52 ± 1.83 mmol/L) compared to P2 (3.79 ± 1.83 mmol/L; d = 0.74) and P4 (3.12 ± 1.83 mmol/L; d = 1.06), whereas P3 (4.23 ± 1.69 mmol/L) elicited higher BLaC values compared to P4 (d = 0.74). CONCLUSION All protocols caused an improved cognitive function and neuromuscular performance. The former may be related to enhanced noradrenergic activation or exercise specificity which induced an improved stimulus processing. The latter may be explained by a possible post-activation performance enhancement effect on jump and sprint performance. A shorter relief duration in W:R as opposed to sprint distance per interval produced higher BLaC values. The protocols may serve as reference data for improved RTS decision-making in elite female soccer players.

Abstract
OBJECTIVES To explore perceptions and beliefs of elite athletics (track and field) athletes, coaches, and health professionals, towards the use of injury prediction as an injury risk reduction strategy. DESIGN Cross-sectional study. METHOD During the 2022 European Athletics Championships in Munich, registered athletes, coaches, and health professionals were asked to complete an online questionnaire on their perceptions and beliefs of injury prediction use as an injury risk reduction strategy. The perceived level of interest, intent to use, help, potential stress (psychological impact) and dissemination were assessed by a score from 0 to 100. RESULTS We collected 54 responses from 17 countries. Elite athletics stakeholders expressed a perceived level of interest, intent to use, and help of injury prediction of (mean ± SD) 85 ± 16, 84 ± 16, and 85 ± 15, respectively. The perceived level of potential stress was 41 ± 33 (range from 0 to 100), with an important inter-individual variability in each elite athletics stakeholder's category. CONCLUSIONS This was the first study investigating the perceptions and beliefs of elite athletics stakeholders regarding the use of injury prediction as an injury risk reduction strategy. Regardless of the stakeholders, there was a high perceived level of interest, intent to use and help reported in this potential strategy.

Abstract
Assessment of the posterior lateral knee pain poses diagnostic challenges, requiring accurate evaluation of various structures in light of the medical history and physical examination. Despite substantial progress in the ultrasonographic diagnosis of musculoskeletal disorders, the current protocol (EURO-MUSCULUS/USPRM. Basic scanning protocols for knee) fails to conduct a comprehensive investigation into the intricate, tendons, and ligaments of the posterior lateral knee. This pictorial review aims to bridge this gap by offering a systematic approach to utilize ultrasound examination of the less-discussed structures in this specific region. Providing cadaveric and magnetic resonance images, this essay demonstrates the efficacy of ultrasound in diagnosing posterior lateral knee pain. Notably, pathologies such as ligamentous sprains and tears are clearly discernible. Moreover, the integration of ultrasound guidance plays a vital role in reducing the risk of inadvertent neurovascular injury during injection, such as the common peroneal nerve and lateral genicular artery. This comprehensive approach will enhance clinicians' understanding and equip them with effective management strategies for posterior lateral knee pain.Critical relevance statement In this visual exposition, we delve into the intricacies of the posterior lateral corner of the knee. Offering a methodical approach to employ ultrasound for visualization of the less-explored structures within this region, the authors aim to enhance the diagnosis in posterior lateral knee pain.Key points1. Ultrasound excels at revealing intricate structures in the posterior lateral knee.2. Due to proximity of vital structures, extreme caution is crucial during injections.3. Employing dynamic scan and understanding ligaments enables a comprehensive exploration of pathologies.

Abstract
CONTEXT While the relationship between high-impact sports like football and basketball and the development of knee osteoarthritis is well established, the impact of martial arts on the knee joint remains unclear. OBJECTIVE To compare the imaging abnormalities of knee joints and T2 relaxation times of cartilage in professional martial arts athletes and healthy controls. DESIGN Cross-Sectional Study. SETTING Hospital imaging center. PATIENTS OR OTHER PARTICIPANTS Nine asymptomatic professional martial arts athletes and eighteen healthy volunteers. MAIN OUTCOMES MEASURE(S) 3T magnetic resonance imaging (MRI) of the knee was performed on the bilateral legs of athletes and the dominant leg of controls. The MRI protocol included conventional sequences used for morphological assessment (cartilage, meniscus, ligaments, joint effusion, and bone marrow edema) and T2 mapping used for quantitatively evaluating the cartilage. Knee cartilage was manually divided into eight regions, and T2 relaxation times of the corresponding subregions were measured. Fisher's exact test and t-test were utilized to compare the frequency of lesions and cartilage T2 values both among groups and between the athletes' limbs. P<0.05 was considered significant. RESULTS Professional martial arts athletes exhibited significantly higher frequencies of cartilage (55.6% vs. 11.1%, P=0.023) and ligament lesions (66.7% vs. 16.7%, P=0.026) compared to control group. Athletes showed higher T2 values in three distinct cartilage segments: the central weightbearing of medial femoral condyle (P=0.006), medial tibial plateau (P=0.012), and trochlea (P=0.032) when compared to the controls. Additionally, the dominant leg of athletes showed significantly higher T2 values compared to their non-dominant legs. CONCLUSIONS The findings demonstrated the impact of martial arts on the knee joint, characterized by higher prevalence of lesions and elevated cartilage T2 values, particularly in the medial compartment. The dominant legs of martial arts athletes seem to have higher risk of cartilage degeneration due to the observed interlimb differences in T2 values.

Abstract
PURPOSE To describe injury incidence, time trends in injury incidence, and injury characteristics among Swedish Olympic athletes over 22 years based on insurance data, as a first step to inform injury preventive measures among Olympic athletes. METHODS The cohort comprised 762 elite athletes (54% males; age 26.5 ± 5.9 years) in 38 sports in the Swedish Olympic Committee support program 'Top and Talent' between 1999 and 2020, with total 3427 athlete-years included. Acute and gradual onset injuries were reported to the insurance registry by the athletes' medical staff. RESULTS A total of 1635 injuries in 468 athletes were registered. The overall injury incidence was 47.7 injuries/100 athlete-years (one injury per athlete every second year). An increasing trend in injury incidence was observed in the first decade 2001 to 2010 (annual change 6.0%, 95% CI 3.3-8.8%), while in the second decade 2011 to 2020 no change was evident (0.4%, 95% CI - 1.9 to 2.7%). Gymnastics, tennis, and athletics had the highest incidence (100.0, 99.3, and 93.4 injuries/100 athlete-years, respectively). Among sport categories, mixed and power sports had the highest incidence (72.8 and 69.5 injuries/100 athlete-years, respectively). Higher incidences were seen in the younger age groups (≤ 25 years) in mixed and skill sports. The injury incidence was comparable between male and female athletes, and summer and winter sports. Most injuries occurred in the lower limb, and specifically the knee (24%), foot/ankle (15%) and spine/pelvis (13%). CONCLUSION The results on injury patterns in different sports and age groups may guide preventive focus for health and performance teams working with Olympic athletes. LEVEL OF EVIDENCE II.

Abstract
Pseudoaneurysms are relatively common entities encountered in clinical practice; however, pseudoaneurysms of the profunda femoris artery are rarely reported in literature. Due to the nonspecific presentation of pseudoaneurysms, diagnosis can be difficult and delayed. We report a case of a 14-year-old athlete diagnosed with spontaneous pseudoaneurysm of profunda femoris artery following a sports injury. Presentation, diagnostic workup, treatment, and complications are described.

Abstract
BACKGROUND Following anterior cruciate ligament reconstruction (ACLR), many athletes do not return to their sport, often driven by concerns about re-injury. Psychological support strategies might help, but are not routinely included in rehabilitation after ACLR. The BAck iN the Game (BANG) intervention is a 24-week eHealth program delivered via smartphone application (app), beginning directly after ACLR, with a self-directed approach that aims to target the specific challenges athletes encounter in rehabilitation. AIM To describe athletes' experiences of using the BANG app during rehabilitation, to support returning to sport following ACLR. METHOD Participants were athletes, in contact and/or non-contact pivoting sports, who had ACLR with the goal to return to sports. Semi-structured, individual interviews were conducted 6-10 months after their ACLR; all had access to the BANG intervention. Verbatim transcripts were analysed with a qualitative content analysis. RESULTS The 19 participants were 17-30 years, mean 21.6 years (SD 3.5); 7 men and 12 women. The analysis generated three main categories. (A) Interacting with the app illustrated how, when, or why the participants engaged with the app. The app was helpful because of its varying content, the notifications served as reminders and participants stopped using the app when no longer needing it. (B) Challenging experiences with the app illustrated that the app itself came with some difficulties e.g., content not appearing with the right timing and material not tailored to their sport. (C) Supportive experiences with the app reflected how the app facilitated the participants' rehabilitation progress; it included positive aspects of the app content and navigation, boosting their confidence to return to sport, and motivated them to continue with rehabilitation. CONCLUSION The analysis of the interviews illustrates athletes' awareness in interacting with, and the challenging and supportive experiences of using the app. The BANG app might provide support for returning to sport, primarily psychological support, as an adjunct to regular physiotherapy-guided rehabilitation. Athletes' experiences of the BANG app could be improved by healthcare professionals providing additional advice about when to use which content and why.

Abstract
Most clinical stroke patients may have difficulty moving, affecting their self-care ability and quality of life, and causing serious interference with the normal life and work of other family members. At present, in clinical literature, researchers provide functional training for patients with motor disorders through repeated and effective training, which can ultimately effectively promote the recovery of limb function. Therefore, the near-infrared spectroscopy imaging technology (fNIRS) used in this study combines the diagnosis of sports injury with the mechanism of brain function. FNIRS technology has many advantages, such as fast, and non-invasive, and has shown great value in detecting brain activity. Therefore, it has become a promising method in the biomedical field, especially in the field of brain science. Based on the clinical effects of sports injury treatment, fNIRS technology is used to detect the hemodynamic changes of hemoglobin circulation in the patient's brain tissue during training, and to detect the brain activity mechanism in the exercise mechanism, providing a basis for the clinical application of this method.

Abstract
OBJECTIVES Osgood-Schlatter disease is an overuse musculoskeletal pain condition. The pain mechanism is considered nociceptive, but no studies have investigated nociplastic manifestations. This study investigated pain sensitivity and inhibition evaluated through exercise-induced hypoalgesia in adolescents with and without Osgood-Schlatter. DESIGN Cross-sectional study. METHODS Adolescents underwent a baseline assessment comprising clinical history, demographics, sports participation, and pain severity rated (0-10) during a 45-second anterior knee pain provocation test, consisting of an isometric single leg squat. Pressure pain thresholds were assessed bilaterally at the quadriceps, tibialis anterior muscle, and the patella tendon before and after a three-minute wall squat. RESULTS Forty-nine adolescents (27 Osgood-Schlatter, 22 controls) were included. There were no differences in the exercise-induced hypoalgesia effect between Osgood-Schlatter and controls. Overall, an exercise-induced hypoalgesia effect was detected at the tendon only in both groups with a 48 kPa (95 % confidence interval 14 to 82) increase in pressure pain thresholds from before to after exercise. Controls had higher pressure pain thresholds at the patellar tendon (mean difference 184 kPa 95 % confidence interval 55 to 313), tibialis anterior (mean difference 139 kPa 95 % confidence interval 24 to 254), and rectus femoris (mean difference 149 kPa 95 % confidence interval 33 to 265). Higher anterior knee pain provocation severity was associated with lower exercise-induced hypoalgesia at the tendon (Pearson correlation = 0.48; p = 0.011) in participants with Osgood-Schlatter. CONCLUSIONS Adolescents with Osgood-Schlatter display increased pain sensitivity locally, proximally, and distally but similar endogenous pain modulation compared to healthy controls. Greater Osgood-Schlatter severity appears to be associated with less efficient pain inhibition during the exercise-induced hypoalgesia paradigm.

Abstract
BACKGROUND Anterior cruciate ligament (ACL) tears are common sports-related injuries. Their incidence is not the same either for all the sports or for the same sport across various nations. This information is maintained by many sports leagues in their registries. However, very few nationwide registries exist for such injuries. This study is carried out to know the demographic characteristics of patients who underwent ACL reconstruction at our hospital in India.
AIM To know the demographic characteristics of patients who underwent ACL reconstruction at a tertiary care hospital in India.
METHODS All the patients who underwent ACL reconstruction from January 2020 to December 2021 were retrospectively studied. Patients with multi-ligament injuries or a history of previous knee surgery were excluded. The patients’ history was obtained from the hospital records, they were interviewed telephonically, and online questionnaires were given. Their demographic data was analyzed and compared to the existing literature.
RESULTS A total of 124 patients were operated on for ACL reconstruction during this period. The mean age of the patients was 27.97 years. One hundred and thirteen patients (91.1%) were male and 11 (8.9%) were female. The majority of the patients (47.6%) sustained this injury by road traffic accidents (RTA) followed by sports-related injuries (39.5%). The commonest presenting complaint was giving way of the knee in 118 patients (95.2%). The mean duration from the injury to the first hospital visit among the patients was 290.1 d. The mean duration from the injury to surgery was 421.8 d.
CONCLUSION ACL patients’ demography is different in developing nations as compared to the developed world. RTA are the leading cause of ACL injuries and are followed by recreational sports as a cause. There is delayed access to healthcare leading to delayed diagnosis as well as even greater time to surgery. This, in turn, leads to poorer prognosis and longer rehabilitation. National registries for developing nations are the need of the hour due to the different demographics of ACL injuries in developing countries.

Abstract
OBJECTIVE Humeral fractures are common in arm wrestling and other sports and military activities requiring similar movements; however, the precise mechanism is poorly understood. Here, we present an overview of the characteristics, possible mechanisms, and treatment of humeral shaft fractures sustained during arm wrestling. METHODS We reviewed 8 years (January 2013 to January 2021) of medical records and retrospectively analyzed data from 27 patients with humeral shaft fractures sustained during arm wrestling. The clinical data included sex, age, affected arm, alcohol consumption, muscle warm-up, history of competitive participation, opponents' characteristics, wrist position, and post-fracture radial nerve injuries. The fracture configurations were radiographically assessed and analyzed. Surgical management included single or dual plating. Scores on the Disability of the Arm, Shoulder, and Hand questionnaire (DASH) were evaluated preoperatively and postoperatively at the last follow-up visit. RESULTS All fractures sustained during arm wrestling were spiral fractures of the distal third of the humerus. Of these, 11 were 12-A1 type and 16 were 12-B2 type with a wedge fragment. The two subtypes differed in the total fracture line length (12-A1: 0.18 ± 0.04; 12-B2: 0.23 ± 0.04; P < 0.001). The radial nerve injury rate was 0/11 (0%) in patients with 12-A1 type fractures and 7/16 (43.8%) in patients with 12-B2 type fractures (P = 0.011). Most patients were young men (mean age, ~25 years) with a history of competitively participating in arm wrestling for >2 years. Cold seasonal temperatures and a lack of warm-ups increased the risk of injury. All patients showed improved DASH scores at the last follow-up (12-A1:77.82 ± 5.14 to 10.25 [5.38]; 12-B2:78.91 ± 7.46 to 8.95 [3.17]; P < 0.001). No significant differences were observed among the different surgical treatments. CONCLUSIONS Individuals who participated in arm wrestling were at risk of humeral shaft fractures (type 12-A1 or 12-B2). The 12-B2 type occurs with a wedge fragment and is frequently accompanied by radial nerve injuries. The characteristics of arm-wrestling fractures and the mechanism(s) underlying these fractures can help orthopedic surgeons understand the causes of these fractures and similar fractures sustained in traditional sports. This understanding will help surgeons choose more effective surgical treatments that will result in more desirable functional outcomes and a faster return to work.

Abstract
PURPOSE The rapid development of winter sports requires investigation on injuries in Chongli district, Zhangjiakou city, one of the ski sites of the 2022 Winter Olympics. Careful evaluation is required to observe which injuries are caused under what circumstances, and then we can make corresponding preventive measures and recommendations based on the results. METHODS In this retrospective study, the data of injury cases at ski resorts in China (Chongli district) and Japan were analyzed to provide a reference for the ongoing injury prevention at ski resorts. We collected data on injuries at Wanlong and Fulong ski resorts in Chongli district during the 2017-2018 and 2018-2019 ski seasons. We referred to the skiing injury report issued in February 2020 of a nationwide ski safety statistical service - Japan Ski Safety Association. The causes of injury and specific injured body parts were analyzed based on the data of Chinese and Japanese ski resorts. Statistical significance has been calculated using the Chi-square test. RESULTS During the 2019-2020 ski season in Japanese ski resorts, the number of reported injuries per 10,000 skiers was 0.93, of which 457 (17.3%) were over 50 years old, accounting for a large proportion of injuries, meanwhile in Chongli ski resort, the injury rate of skiers aged 50 and over was 7.1%. The knee joint (23.7% at Wanlong ski resort and 28.4% in Japanese ski resorts) was the most injured body part among Chongli and Japanese skiers. Among snowboarders, shoulder joint injury (17.7% in Japanese ski resorts) was the most common, and injury on hands and fingers (16.3% in Wanlong ski resorts) was the most common. Head injury rates are similar in Chongli, China and Japanese ski resorts (8.2% and 8.7%, respectively). CONCLUSION Our analysis demonstrated that injury data recorded among young skiers was higher in Chinese ski resorts (Chongli district) than that in Japanese ski resorts, and elderly skiers made up a larger proportion of skiing injuries in Japanese resorts. Thus, according to our research, the protection of knee joints, shoulder joints, and hands and fingers should be taken seriously. It should pay attention to the teaching of ski poles (for finger protection), and use protective devices such as knee pads, helmets, etc.

Abstract
OBJECTIVE The primary objective was to determine the effect of the COVID-19 pandemic on volume, demographics, and mechanisms of injury (MOI) for patients seen at an urban multidisciplinary concussion center. During the first phase of the pandemic in the United States, stay-at-home orders led to decreased group activities and required cancellation of outpatient appointments or initiation of telemedicine visits. METHODS This study was a retrospective chart review of 3500 patient electronic medical records (EMR). Patients aged 1-99 years were eligible if they had been seen at New York University Langone Health Concussion Center during March 1-December 31, 2019 (control/pre-pandemic period) or during the same period in 2020 (pandemic period). Injury date, appointment date, age, sex, and MOI were captured; statistical analyses were performed using Stata17 (StataCorp, College Station, TX). RESULTS There were 48% fewer visits during the COVID-19 pandemic period compared to the 2019 control period. There was a decreased proportion of pediatric patients (15% control, 6% pandemic; p = 0.007, chi-square test). Fewer concussions were related to team sports (21% control, 5% pandemic; p < 0.001), and a greater proportion were caused by bicycle accidents (4% control, 8% pandemic; p = 0.037) and assault/domestic violence (3% control, 9% pandemic; p < 0.001). CONCLUSION The relative proportions of concussion MOI, age distributions, and visit volumes were significantly associated with pre-pandemic vs. pandemic periods, suggesting that COVID-19 changed concussion epidemiology during the pandemic period. This study demonstrates how epidemiologic data may inform future resource allocation during public health emergencies.

Abstract
Stress fractures are a common injury that present in athletes because of the high intensity and repetitive nature of many sports. These injuries require a high index of suspicion in the treating clinician to allow for timely management. Though most low-risk fractures heal well with conservative management, high-risk stress fractures as well as any fracture in the elite athlete may warrant surgical intervention as well as an augmented treatment and rehabilitation regimen.

Abstract
PURPOSE Little is known about risk factors for sustaining a posterior cruciate ligament (PCL) rupture. Identifying risk factors is the first step in preventing a PCL rupture from occurring. The morphology of the knee in patients who ruptured their PCL may differ from that of control patients. The hypothesis was that the intercondylar notch dimensions, 3-D volumes of the intercondylar notch and, the 3-D volumes of both the ACL and the PCL were correlated to the presence of a PCL rupture. METHODS The magnetic resonance imaging (MRI) scans of 30 patients with a proven PCL rupture were compared to 30 matched control patients with proven intact ACL and PCL. Control patients were selected from patients with knee trauma during sports but without cruciate ligament injury. Patients have been matched for age, height, weight, BMI, and sex. The volumes of the intercondylar notch and both the ACL and PCL were measured on 3D reconstructions. Second, the bicondylar width, the notch width, and the notch width index were measured of all subjects. The relationship between our measurements and the presence of a PCL rupture was analysed. RESULTS The results show a significant difference in the volumes of the intercondylar notch and the ACL between patients with a ruptured PCL and control patients. Patients with a PCL rupture have smaller intercondylar notch volumes and smaller ACL volumes. There were no significant differences in the bicondylar width, notch width, and notch width index. In the control patients, a significant correlation between the volume of the PCL and the volume of the ACL was found (0.673, p < 0.001). CONCLUSION Patients with a PCL rupture have smaller intercondylar volumes and smaller ACL volumes when compared to control patients. Second, patients with smaller ACL volumes have smaller PCL volumes. This study shows, for the first time, that there are significant size and volume differences in the shape of the knee between patients with a PCL rupture and control patients. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE The effect of knee cartilage defects that are detected during partial meniscectomy remains controversial in terms of the long-term prognosis on knee function. This study aimed to investigate the effect of concurrent medial compartment focal cartilage lesions on the long-term prognosis of knee function in patients who underwent arthroscopic partial medial meniscectomy for traumatic medial meniscal tears. METHODS This retrospective study analyzed 46 patients who underwent arthroscopic partial medial meniscectomy between 1991 and 2008 by a single surgeon. Twenty-one patients who underwent arthroscopic partial medial meniscectomy due to traumatic meniscal tear had focal chondral lesions only at the medial compartment, and these patients were assigned to group A. Twenty-five patients who had no cartilage lesions in any compartments were assigned to group B. The age, sex, body mass index (BMI), follow-up time, age at the time of surgery, clinical and radiological scores, and perioperative arthroscopy findings were analyzed. RESULTS The mean follow-up time was 20 ± 3.7 years. No significant difference was found in the demographic data, and the average age of the patients at the time of operation was 35 ± 9.5 years. Both groups had improved Lysholm score at the last follow-up. Although no difference was found between the groups during the preoperative period, group B had a higher Lysholm score at the last follow-up than group A. The mean International Knee Documentation Committee (IKDC) and Knee injury and Osteoarthritis Outcome Score (KOOS) scores at the last follow-up were significantly higher in group B. The mean Kellgren-Lawrence grades in the operated knees of group A were higher than those of group B. In group A, a negative correlation was found between the BMI and postoperative Lysholm (r = - 0.461, p = 0.03) IKDC (r = - 0.433, p = 0.05) and KOOS (r = - 0.565, p = 0.008) scores. In group B, no correlation was found between BMI and any score. CONCLUSION Among patients who underwent arthroscopic partial medial meniscectomy with an average follow-up of 20 years, those with concurrent focal cartilage defect in the medial compartment had clinically and radiologically worse outcomes than patients without any cartilage defect. Therefore, orthopedic surgeons should be meticulous before performing any arthroscopic partial medial meniscectomy in case of concurrent cartilage lesion. LEVEL OF EVIDENCE Level III.

Abstract
As the modern golf swing has changed, the incidence of knee pain in professional golfers is increasing. For those with previous knee injuries, developing a golf-swing modification that reduces knee loading may be necessary to recover performance after injury. The purpose of this study was to test whether ball position modification reduces knee joint load in a golf swing. Thirteen male professional golfers participated in the study. Golf swings were captured using a three-dimensional motion capture system and two force platforms, with conditions for self-selected ball position and eight additional ball positions. Knee internal rotation and adduction moments were calculated. The length of one golf ball (4.27 cm) backward ball position (closer to the golfer) significantly reduced the peak internal rotation moment of the lead knee (- 13.8%) (p < 0.001) and the length of one golf ball (4.27 cm) away from the target ball position significantly reduced the peak adduction moment of the lead knee (- 11.5%) (p < 0.001) compared with that of the self-selected ball position. Based on these observations, we conclude that the backward ball position modification might be suggested for golfers with anterior cruciate ligament injuries, and the away from the target modification might be suggested for golfers with medial compartment knee osteoarthritis.

Abstract
OBJECTIVE Young players experience pressure to focus on ice hockey at the exclusion of other sports in order to improve chances of success. Early specialization in other sports has been associated with increased injury without the benefit of improved success. The objective of the current study was to investigate whether earlier specialization results in increased injury without higher rates of career success. This study also aimed to compare rates of injury in athletes at various levels of competition. METHODS An original survey was issued to men's ice hockey players at the juniorA, collegiate, and professional levels. The survey consisted of 34 questions on various demographic, specialization, and injury variables. All participants were >18 years of age. RESULTS The survey was completed by 101 athletes. The mean age at specialization was 13 (±4) overall and 14 (±3), 13 (±4), and 11(±4) for professional, collegiate, and junior players, respectively. There was no difference in age at specialization between each group and professional players did not specialize earlier than the remainder of the cohort as a whole (p > 0.05). There was no significant correlation between age at specialization and total injuries (p > 0.05). There was no difference in concussions causing missed play time between groups (p > 0.05) but professional players had more overall concussions and underwent more surgeries due to hockey-related injuries (p = 0.01). CONCLUSIONS Specializing exclusively in ice hockey earlier in life was not associated with playing professionally. Both collegiate and professional players do not tend to specialize prior to age 12. Age at specialization was not associated with overall number of injuries. Professional players with longer careers appear to sustain more concussions and undergo more surgery.

Abstract
OBJECTIVES Researchers have often struggled to successfully implement injury prevention strategies in real-world practice. This is despite such strategies proving successful in reducing overall injury incidence and burden. It has been hypothesised that this may be because the behavioural and contextual factors related to sports injury are not fully understood. Such factors stem from multiple key stakeholders, including the athlete. The primary aim of this study was to investigate athletes' knowledge and attitudes towards injury, injury reporting and prevention, as well as some of the barriers that may impact the future implementation of prevention strategies. DESIGN Qualitative; with semi-structured interviews following an interpretivist approach. METHODS Twenty-two field hockey athletes, playing in the top-tier Irish Hockey League were interviewed. Data were analysed using reflexive thematic analysis, with three general dimensions containing six higher-order themes. RESULTS The findings highlighted that athletes have a varied understanding of injury, which tends to improve with experience. The reporting of injuries by athletes to members of the coaching staff was relatively poor. This may be due to limited resources and supports available to athletes which also cause challenges to injury prevention. CONCLUSIONS Future injury prevention strategies in field hockey need to account for athletes' varied understanding of what constitutes an injury. Furthermore, policy changes to influence potential barriers to injury may assist in preventing or reducing the number of injuries being sustained by athletes.

Abstract
QUESTION What is the effect of injury prevention programs that include balance training exercises on the incidence of ankle injuries among soccer players? DESIGN Systematic review of randomised trials with meta-analysis. PARTICIPANTS Soccer players of any age, sex or competition level. INTERVENTIONS The experimental intervention was an injury prevention program that included balance training exercises. The control intervention was the soccer team's usual warm-up program. OUTCOME MEASURES Exposure-based ankle injury rates. RESULTS Nine articles met the inclusion criteria. The pooled results of injury prevention programs that included balance training exercises among 4,959 soccer players showed a 36% reduction in ankle injury per 1,000 hours of exposure compared to the control group with an injury risk ratio (IRR) of 0.64 (95% CI 0.54 to 0.77). The pooled results of the Fédération Internationale de Football Association (FIFA) injury prevention programs caused a 37% reduction in ankle injury (IRR 0.63, 95% CI 0.48 to 0.84) and balance-training exercises alone cause a 42% reduction in ankle injury (IRR 0.58, 95% CI 0.41 to 0.84). CONCLUSIONS This meta-analysis demonstrates that balance exercises alone or as part of an injury prevention program decrease the risk of ankle injuries. PROSPERO CRD42017054450.

Abstract
Background Sports related injuries are the leading cause of Anterior Cruciate Ligament (ACL) tear in the Western world. Although professional and recreational sporting activities are increasing in Nepal, they are not as common and prevalent in comparison to western world. In contrast, Road Traffic Accident (RTA) is a very common cause of knee injuries in Nepal. Although there are some studies from Nepal mentioning Road Traffic Accidents (RTAs) as the most common cause of ACL injury, no specific studies have primarily investigated the epidemiological and demographic profile of ACL injured patients from this region. we aimed to understand the epidemiological and demographic profile of ACL injured patients and evaluate the mode of injury in a tertiary referral trauma center of Nepal. Methods This was a retrospective descriptive study of a hospital cohort conducted from February 2018 to January 2020. Electronic details were retrieved, telephone interviews conducted and data analysis was done using descriptive analysis on the patients from the fore mentioned dates to complete demographic and epidemiological information. Results A total of 237 patients were enrolled in this study. Among these, 120 patients (50.6%) fell into the age group of 15–30 years with a male to female ratio of 2.7:1. A RTA was the most common cause of ACL injury (38.8%), followed by sports-related injuries in 33.3% and falls in 16.5% of patients. The most common mode of RTA was a two-wheeler accident, and football was the most common sport causing ACL injuries. Sports injury was more common in patients below 30 years of age (OR = 3.5, 95% CI [2.2, 5.7]), whereas RTA was more common in patients above 30 years of age. Sports was the cause of ACL injury in 55.5% of students and RTAs was the commonest cause of ACL injury in office workers. Conclusion Overall males were more frequently injured than females. Road traffic accidents were the most common cause of ACL injury in our subset of patients. Two-wheeler riders were the most commonly injured patients. Sport was the commonest cause of ACL injury in patients below 30 years, and RTA was common in patients above 30 years of age. Sports were the commonest cause of ACL injury in students, while RTA was the most common cause in office workers.

Abstract
BACKGROUND For professional athletes, sports injury has been considered one of the most influential factors determining their athletic careers' duration and quality. High-intensity training and competitiveness of the sports competition are perhaps critical causes of sports-related stress. This article reviews the relevant research on sports injuries and stressor-related disorders. Further, it explores the following three issues in depth: (1) Do physical injuries caused by competitive sports lead to acute or posttraumatic stress disorder for athletes? What are the abnormal stress responses? (2) What diagnoses are currently available for sports injury related traumatic stress disorder? (3) What kinds of psychological rehabilitation are available for trauma-related symptoms in sports injury? How efficient are they in alleviating these symptoms? METHODS The study searched electronic databases, including PubMed, MEDLINE, CINAHL, etc. And reference lists of included papers were also screened. Two researchers selected the literature strictly according to the inclusion criteria and sorted them out. Based on the proved conclusions, the study established a new framework to manage traumatic stress disorders after the injury occurred. RESULTS 16 articles were included in the study. (Q1: N = 10; Q2: N = 3; Q3: N = 3 ) The findings of this review suggested that athletes who suffer from sports injuries are more likely to experience abnormal physiological or psychological stress responses, which may become a massive challenge for athletes to continue their sports careers at a competitive level. However, there is a minimal understanding of addressing sports injury-related traumatic stress disorder from a biological perspective. Thus, it is challenging to build a scientific basis for diagnosis, screening, and treatment. In addition, the current diagnostic tool for athletes stress disorder still heavily relies on subjective measurement, and the treatment plan is not different from that of the general population. CONCLUSIONS It highlighted that sports-related stress disorder could be the greatest challenge to return to competition for injured athletes. The present study indicated the importance of systematically identifying the symptoms of sports-related stress disorder and improving the current diagnosis and treatment system.

Abstract
BACKGROUND/PURPOSE Since badminton has emerged as a frequently played non-contact recreational sport in India, it is essential to document the injury patterns and incidence. However, there is no existing literature on this topic among Indian players. MATERIALS AND METHODS A web-based questionnaire was circulated among recreational badminton players across North India, enquiring about demographic details, injury characteristics, and factors associated with an injury like BMI, warm-up practice, and physical training. RESULTS Data of 237 eligible participants revealed an injury incidence rate of 57.1%. The ankle and dominant-side shoulder were the most common anatomical regions affected. The most common injury types were ligament sprain and muscle/tendon strain. Factors like age, frequency, duration of play, type of footwear, BMI, prior warm-up, court surface, and physical training were significantly associated with injury incidence on univariate logistic regression analysis. On multivariate logistic regression analysis, we found male gender, a lack of prior warm-up, inadequate physical training, and age group between 26 and 30 years to be four independent risk factors for injury. CONCLUSION The recreational badminton player of India had a relatively higher incidence of injury compared with the limited published data from other countries. Modifiable factors like a proper warm-up before the game, regular physical fitness training, and injury awareness programs can reduce the injury rates.

Abstract
OBJECTIVES The aim of this study was to investigate the incidence and characteristics of match and training injuries in elite-level national male beach soccer players. METHOD The incidence, mechanism, location, type, severity, and burden of injuries of the Turkish national beach soccer team were recorded between 2017 and 2019. RESULTS A total of 136 injuries occurred during the study period. Total injury incidence was 238.9 injuries/1,000 match hours (MHs) and 37.7 injuries/1,000 training hours (THs) (p < 0.001). Twenty-seven injuries led to time-loss, and the incidences for match and training injuries were 36.7 and 7.9 per 1,000 hours, respectively. Of medical attention injuries (MAI) caused by trauma, 54.6% (n = 53) were due to another player and, 60.9% (n = 14) of time-loss injuries (TLI) caused by trauma were due to non-contact trauma (p < 0.001). While 82% (n = 91) of training injuries occurred in lower extremities, 29% (n = 9) of match injuries occurred in the head/neck region (p < 0.001). Head injury incidence was 45.9 per 1,000 match hours. Of MAI, 50% (n = 57) were contusion, and 32.1% (n = 9) of TLI were strain (p < 0.001). Also, the most common injury subtype was foot/toe contusion during match and training (19.4%; n = 6, 27.9%; n = 31, respectively). The majority of injuries 91.9% (n = 125) had slight severity. CONCLUSION Head trauma, tendon injury, and foot/toe contusion are important for clinical practice in beach soccer. Protective measures (rule regulation, use of protective equipment, etc.) should be considered to prevent these injuries.

Abstract
BACKGROUND Mobile-gaming athletes sit in the same posture for prolonged periods, contributing to significant health risks. This study investigated the health profiles, fatigue, pain and complaints, and musculoskeletal problems of full-time mobile-gaming athletes. METHODS A total of 50 elite mobile-gaming athletes were involved in this study. They were the starting lineup players from all ten professional teams competing in a top-tier multiplayer online battle arena tournament. A survey was conducted to evaluate their fatigue patterns, pain levels, and complaints. A descriptive analysis was conducted to evaluate the athletes' health profiles [body mass index (BMI), fat ratio], fatigue, number of complaints, and musculoskeletal problems. The associations of career duration with BMI, fat ratio, and the total number of confirmed injuries were then determined using Spearman's rank correlation test. RESULTS A total of 46% and 44% of the participants felt tired frequently and occasionally, while 34% and 58% experienced eyestrain frequently and occasionally, respectively. More than 30% of the participants reported headache and rhinitis. A longer esports career duration was associated with a reduction in BMI (r = -0.272, p = 0.056). Career duration had no significant association with smoking habits (p = 0.666), alcohol habits (p = 0.655), coffee habits (p = 0.946), rounds of games for which the player could maintain concentration (p = 0.253), ease of eyestrain (p = 0.569), tiredness (p = 0.510), dizziness (p = 0.071), or leg numbness (p = 0.318). CONCLUSION The findings of this study stress the significance of esports injuries and indicate preventive measures for both athletes and recreational players.

Abstract
BACKGROUND In this study, the incidence rate of the injury in Winter Paralympic Games was summarized. Besides, to testify the underlying factors of injury incidence heterogeneity, the difference of these events incidence between different Paralympic Winter Games was investigated by meta regression analysis. METHODS Electronic databases were searched for full-text publications on sports related injury in Winter Paralympic Games. And meta-regression was used to analyze the heterogeneity. RESULTS Four studies were included. The incidence of sports related injury was 0.21 (95% CI 0.15-0.31) in all items, 0.22 in female athletes (95% CI 0.12-0.32), and 0.21 in male athletes (95% CI 0.11-0.30), respectively. The incidence of sports related injury was 0.10 (95% CI 0.08-0.12) in alpine skiing, 0.01 (95% CI 0-0.02) in Nordic skiing, and 0.22 in sledge hockey (95% CI 0.05-0.40). Meta-regression suggested the year and the host country couldn't influence the injury incidence. CONCLUSION The present study summarized the incidence of sports related injury in Winter Paralympic Games, indicated similar injury risk between female athletes and male athletes, and accentuated the careful protection on sledge hockey. This study pointed out that sledge hockey with the highest risk of sports related injury should draw great attention to improve the corresponding protective measures to decrease its injury probability.

Abstract
PURPOSE Quadriceps tendon ruptures (QTR) occur predominantly in middle-aged patients through violent eccentric contraction that occurs either when trying to regain balance or during a fall on the hyperflexed knee. The aim of this study was to quantify midterm postoperative results, including strength potential measured via standardized strength tests following acute (< six weeks) quadriceps tendon refixation using suture anchors. METHODS All consecutive patients with QTR who underwent surgical suture anchor refixation between 2012 and 2019 at a single institution with a minimum follow-up of 12 months were retrospectively evaluated. Outcome measures included Tegner Activity Scale (TAS), Lysholm score, International Knee Documentation Committee subjective knee form (IKDC), Knee injury and Osteoarthritis Outcome Score (KOOS) subscales, return to work rates, and Visual Analog Scale (VAS) for pain. Additionally, a standardized clinical examination and an isometric strength assessment of knee extension and flexion were performed. RESULTS A total of 17 patients (median age 61.0 [25-75% IQR 50.5-72.5]) were available for final assessment at a mean follow-up of 47.1 ± SD 25.4 months. The majority of patients were male (82.4%) and most injuries occurred due to a fall on the hyperflexed knee (76.5%). The average time interval between trauma and surgery was 12.7 ± 7.5 days. Patients achieved a moderate level of activity postoperatively with a median TAS of 4 (3-5.5) and reported good to excellent outcome scores (Lysholm score: 97 (86.5-100); IKDC: 80.7 ± 13.5; KOOS subscales: pain 97.2 (93.1-100), symptoms 92.9 (82.5-100), activities of daily living 97.1 (93.4-100), sport and recreation function 80 (40-97.5) and knee-related quality of life 87.5 (62.5-100). All patients were able to fully return to work and reported little pain [VAS: 0 (0-0)]. No postoperative complications were reported. Strength measurements revealed a significant deficit of knee extension strength in comparison to the contralateral side (p = 0.011). CONCLUSION Suture anchor refixation of acute QTR leads to good functional results and high patient satisfaction without major complications. Isometric knee extension strength, however, may not be fully restored compared to the unaffected side.

Abstract
This systematic video analysis of 21 anterior cruciate ligament (ACL) injuries sustained by elite-level netball players during televised games, describes the situation, movement pattern and player behaviour, providing insight regarding the injury mechanism. Seventeen of the ACL injuries occurred from jump-landing actions and only two from cutting manoeuvres. A common scenario was identified for 11 players. In this scenario, players were decelerating rapidly after jumping to receive a high pass, utilising a double-footed landing with a wide base of support (WBOS). Deceleration appeared to be applied predominantly via the injured leg with the knee extended and foot planted. Often the players appeared unbalanced on landing leaning too far back. ACL injury risk was possibly exacerbated by the players head turning away from the injured side. A further compressive knee moment may have been placed on the lateral aspect of the knee by bringing the ball from a high position to a low position at the estimated time of injury. Players may benefit from landing technique training programmes that encourage shoulder-width foot landings, with ≥30° knee flexion, a small amount of plantar-flexion and good balance. Incorporating challenges to players balance and ability to cope with perturbations may also be beneficial. Training programmes should include instruction on securing the ball in a stable above pelvis-level position after receiving a pass and bringing their whole body around during landing into the direction of their next pass, rather than simply turning their head to look.

Abstract
INTRODUCTION This systematic review investigates which image appearances are most common when diagnosing lower limb stress fractures using ultrasound imaging, with the aim of outlining an image critique guideline for operators to support confident diagnoses. METHOD A comprehensive literature search of medical databases and handsearching was undertaken to identify relevant studies. All studies were critically examined for quality using the CASP critical appraisal tool. Results from eight studies were combined and interpreted using a narrative synthesis. FINDINGS A clear outline of common stress fracture appearances using ultrasound were identified in a combined total of 119 participants. Each finding was ranked according to its popularity. Periosteal thickening (78/119) and cortical disruption/irregularity (83/119) were noted in all eight studies. Hypervascularity of the periosteum visualised by colour Doppler imaging (66/119) was reported in six of the eight studies. Soft tissue hypervascularity (13/119), bony callus formation (5/119) and cortical break (22/119) were seen in three studies. CONCLUSIONS Based on the findings, we offer a guideline of the most significant preliminary image findings to be utilised by operators when examining athletes suspected of having lower limb stress fractures. The results show a gap in research for evaluating changes in appearance depending on the injury severity. Further research into distinguishing stress fractures from pathological involvement may in future reduce reliance on plain film radiography.

Abstract
Objectives: To study the value of X-ray analysis method of ankle fracture based on injury mechanism to improve the imaging diagnosis level of ankle fracture. Methods: This study was conducted from January 2016 to December 2019. It included 105 cases of fractures caused by sprained ankle joints. Their age was between 21-81 years with an average of 49.5 years, The traditional X-ray analysis method (Group-A) and the injury mechanism-based ankle fracture X-ray analysis method (Group-B) were used to analyze X-ray image data. Group-B also performed Weber classification and Lauge-Hansen classification on cases. Installment. Results: Of the 105 patients with ankle fractures, 97 patients in Group-B were able to make Lauge-Hansen classification. Of these 97 ankle fractures, 137 were found in Group-A, and 158 were found in Group-B. The wrong diagnosis of fracture in Group-A was 18%, and the wrong diagnosis of fracture in Group-B was 0.5%. There was a statistically significant difference between the two groups (P <0.05). Conclusion: The X-ray analysis method of ankle fractures based on injury mechanism can effectively improve the detection rate of hidden ankle fractures and high fibular fractures, and reduce the missed diagnosis, which is superior to the traditional X-ray analysis methods. At the same time, Weber classification, Lauge-Hansen classification and staging can be made for most cases, which is conducive to guiding clinical treatment.

Abstract
OBJECTIVE The objective of this pilot study was to examine the preliminary feasibility and efficacy of in vivo exposure therapy (IVET) to decrease injury-related fear in females with history of ACLR. DESIGN Pilot Study. SETTING Sports Medicine Research Laboratory. PARTICIPANTS 12 female participants with history of ACLR (≥ 1 year post-operative) were randomized into a 5-week IVET group (n = 6) or 5-week sham physical activity (PA) monitoring group (n = 6). MAIN OUTCOME MEASURES The independent variables were Group and Time. The dependent variables were the Photographic Series of Sports Activities for ACLR (PHOSA-ACLR) and the Tampa Scale of Kinesiophobia-11 (TSK-11) scores. A Group x Time repeated measures two-way analysis of variance was completed for the PHOSA-ACLR and the TSK-11. Partial η2 effect sizes were used to examine clinically meaningful differences. RESULTS High retention and adherence rates were observed in the intervention group. The PHOSA-ACLR exhibited a significant main effect for Time (F1,10 = 9.92, p = 0.01, partial η2 = 0.50), but not for Group. No statistically significant or clinically meaningful differences were observed for the TSK-11. CONCLUSION Both groups exhibited decreased injury-related fear for specific functional tasks. Future research should further examine the efficacy of IVET and PA monitoring to decrease injury-related fear in patients after ACLR.

Abstract
Ankle sprain is the most common injury in athletic populations. Ligament and tendon pathologies of the ankle are common, ranging from traumatic injuries to degeneration leading to chronic pain and acquired foot deformities. MRI is the imaging modality of choice to evaluate tendon and ligament pathology of the ankle, specifically derangements of tendons and ligaments. 3-T MRI offers improved imaging characteristics relative to 1.5-T MRI, allowing for better delineation of anatomic detail and pathology. This article provides a review of the anatomy and common pathologies of the ankle ligaments and tendons using high-resolution 3-T MRI.

Abstract
BACKGROUND Proprioceptive training in the aquatic environment is more beneficial owing to water properties. The primary goal of the present study was to investigate the effectiveness of the incorporation of innovative aquatic proprioceptive training into conventional accelerated land-based rehabilitation protocol in knee function and joint position sense in male athletes after anterior cruciate ligament reconstruction (ACLR). METHODS A total of 38 athlete male athletes with ACLR were randomly assigned to two rehabilitation groups. The conventional therapy group (CT) (n=19) received conventional rehabilitation for 6 weeks, while the hydrotherapy group (HT) (n=19) received the same conventional rehabilitation, in addition to 12 sessions of innovative aquatic proprioceptive training. The outcomes included the joint position sense (JPS) errors, visual analog scale (VAS), and international knee documentation committee (IKDC). Repeated measures analysis of variance (ANOVA) was used to compare the means between the two groups. Cohen's d from an independent t-test was used to calculate the effect sizes for all variables after the intervention for both groups. RESULTS Base on the results, there were a significant difference in absolute errors (AE) (FAE=56.231, P<0.001) and variable errors (VE) (FVE=60.245, P<0.001) between the two groups. No significant differences were detected in constant error (CE), VAS, and IKDC between the two groups (P>0.05). Both groups displayed a significant difference in terms of AE, VE, VAS, and IKDC after the intervention (P<0.05). Percent changes after the intervention for AE(69.19%), VE (68.20%), CE (65.20%), VAS37.50%, and IKDC (38.61%) were greater in the HT group, compared to the CT group. CONCLUSION As evidenced by the obtained results, innovative aquatic proprioceptive training incorporate into the conventional rehabilitation accelerated protocol offers the improvement of proprioception efficiency for individuals with ACL reconstruction. Therefore, it could be useful to clinicians when designing rehabilitation protocol to ensure the optimal engagement of proprioception.

Abstract
OBJECTIVE Few studies have investigated injury incidence in field hockey. The aim of this systematic review was to determine the incidence and characteristics of injury in male field hockey athletes. DESIGN Prognosis systematic review with meta-analysis. LITERATURE SEARCH MEDLINE via PubMed; EMBASE via Ovid; CINAHL via EBSCO; SPORTDiscus; and Web of Science were searched. STUDY SELECTION CRITERIA Prospective studies and retrospective studies employing video analysis, written in English and published in peer-reviewed journals, expressing the incidence of injury in male field hockey athletes were included. Studies must have been of a duration of a minimum one season or one tournament. Studies were screened by two authors, assessing the eligibility of each record. Following selection of the studies, data were extracted by the two authors. DATA SYNTHESIS Levels of heterogeneity were assessed in aggregate data using the I2 statistic. RESULTS In total, 1722 records were identified. Twelve studies were included in the review. Injury incidence ranged from 4.5 to 57.9/1000h (I2 = 98.5%). Nine studies were undertaken in tournament settings, with the remaining three conducted in club-based athletes in season-long settings. When a medical attention definition was used, there was a pooled incidence rate of 48.1/1000h, all in tournament studies. Contusions and muscle strains were the most frequently reported injury types, while the lower limb was the most common site of injury. Contact injuries were most common in tournament-based studies, while non-contact was more common in season-long studies. CONCLUSION Prospective, season-long epidemiological studies investigating injury incidence in field hockey are lacking.

Abstract
OBJECTIVES A variety of modifiable risk factors has been suggested to predict musculoskeletal injury in sports. Screening paradigms and exercise-based prevention programs, so far, frequently focused on physical parameters such as strength, balance or flexibility. However, less is known with regard to the impact of brain function. We investigated the relation between cognition and the occurrence of injury in athletes. DESIGN Systematic review. METHODS Database searches using Pubmed, Web of Science and Google Scholar returned nine cohort and case-control studies, which almost exclusively examined college athletes engaging in open skill sports. Methodological quality, rated by means of a modified Downs and Black checklist, was moderate (12/17 points). RESULTS Seven out of the nine included studies suggested that lower-order cognitive function (i.e. visuomotor reaction time) is systematically associated with the occurrence of injury. No paper examined the impact of executive function. CONCLUSIONS Despite initial evidence pointing towards a potentially injury-predictive role of lower-order cognitive function, several issues including the use of more variable populations and outcomes remain to be addressed before definitive recommendations for clinicians can be made.

Abstract
Introduction The COVID-19 lockdown resulted in decreased vehicle use and an increased uptake in cycling. This study investigated the trends in cycling-related injuries requiring orthopaedic intervention during the COVID-19 lockdown period compared with similar time periods in 2018 and 2019. Methods Data were collected prospectively for patients in 2020 and collected retrospectively for 2019 and 2018, from hospitals within four NHS Scotland Health Boards encompassing three major trauma centres. All patients who sustained an injury as a result of cycling requiring orthopaedic intervention were included. Patient age, sex, mechanism of injury, diagnosis and treatment outcome from electronic patient records. Results Number of injuries requiring surgery 2020: 77 (mean age/years – 42.7); 2019: 47 (mean age/years - 42.7); 2018: 32 (mean age/years – 31.3). Overall incidence of cycling injuries 2020: 6.7%; 2019: 3.0%; 2018: 2.1%. Commonest mechanism of injury: fall from bike 2020 n = 54 (70.1%); 2019 n = 41 (65.1%); 2018 n = 25 (67.6%). Commonest injury type: fracture 2020 n = 68 (79.1%); 2019 n = 33 (70.2%); 2018 n = 20 (62.5%). Commonest areas affected: Upper extremity: 2020 n = 45 (58.5%); 2019 n = 25 (53.2%); 2018 n = 25 (78.1%). Lower extremity: 2020 n = 23 (29.9%); 2019 n = 14 (29.7%); 2018 n = 7 (21.8%). Conclusion A significant increase in the number of cycling related injuries requiring orthopaedic intervention, a greater proportion of female cyclists and an older mean age of patients affected was observed during the COVID-19 lockdown period compared with previous years. The most common types of injury were fractures followed by lacerations and fracture-dislocations. The upper extremity was the commonest area affected.

Abstract
BACKGROUND Social and structural determinants of health (SDOH) are the conditions in which individuals are born, live, learn, work, play, worship, and age. These drivers of health are integral in contextualizing the understanding and prevention of sport and recreation injury (SRI), and recognizing their impact is necessary to provide a complete and accurate picture of health and health outcomes related to injury. MAIN: Reducing disparities and achieving equity in sports and recreation is possible in part by improving data collection methodologies and utilization. Often, many SDOH have considerable effect on SRI. Although SRI epidemiology frequently examines differences by sex, there is limited inclusion of factors such as socioeconomic status, housing, gender, and food security, in sport specific data sources or in analysis of sport recreation and injury using other sources (e.g. administrative data). The ongoing dual epidemics in the United States - racism and COVID-19 - have emphasized the importance of having and utilizing SDOH data to reduce the burden of injury and disproportionate effects on our diverse population. CONCLUSION Moving forward, to address disparities in SRI, SDOH must be included as a part of research priorities, health related goals, and policies. This difference can be made in developing consistency in data collection and utilization. This will provide an accurate picture of the intersections and interdisciplinary changes required to design the best approach to problems to develop solutions. Future data collection and utilization should prioritize SDOH.

Abstract
Background Chronic ankle instability, developing from ankle sprain, is one of the most common sports injuries. Besides it being an ankle issue, chronic ankle instability can also cause additional injuries. Investigating the epidemiology of chronic ankle instability is an essential step to develop an adequate injury prevention strategy. However, the epidemiology of chronic ankle instability remains unknown. Therefore, the purpose of this study was to investigate the epidemiology of chronic ankle instability through valid and reliable self-reported tools in active populations. Methods An electronic search was performed on PubMed and Web of Science in July 2020. The inclusion criteria for articles were peer-reviewed, published between 2006 and 2020, using one of the valid and reliable tools to evaluate ankle instability, determining chronic ankle instability based on the criteria of the International Ankle Consortium, and including the outcome of epidemiology of chronic ankle instability. The risk of bias of the included studies was evaluated with an adapted tool for the sports injury review method. Results After removing duplicated studies, 593 articles were screened for eligibility. Twenty full-texts were screened and finally nine studies were included, assessing 3804 participants in total. The participants were between 15 and 32 years old and represented soldiers, students, athletes and active individuals with a history of ankle sprain. The prevalence of chronic ankle instability was 25%, ranging between 7 and 53%. The prevalence of chronic ankle instability within participants with a history of ankle sprains was 46%, ranging between 9 and 76%. Five included studies identified chronic ankle instability based on the standard criteria, and four studies applied adapted exclusion criteria to conduct the study. Five out of nine included studies showed a low risk of bias. Conclusions The prevalence of chronic ankle instability shows a wide range. This could be due to the different exclusion criteria, age, sports discipline, or other factors among the included studies. For future studies, standardized criteria to investigate the epidemiology of chronic ankle instability are required. The epidemiology of CAI should be prospective. Factors affecting the prevalence of chronic ankle instability should be investigated and clearly described.

Abstract
OBJECTIVE To evaluate the incidence of knee bone marrow edema-like signal and its changes before and after running a half marathon running in asymptomatic amateur marathon runners to explore the impact of the half marathon on knee bone marrow edema-like signal. METHODS 50 asymptomatic amateur marathon runners (30 males, 20 females) were recruited. T1-weighted imaging (T1WI), fat-suppressed protein density weighted imaging (fs-PDWI) and three-dimensional double-echo steady-state (3D-DESS) sequence on the right knee were performed before and within 3 h after a half-marathon running. 20 healthy volunteers were recruited as control. According to the whole-organ magnetic resonance imaging score (WORMS) system, the involvement of bone marrow edema-like signal in 15 regions of knee was graded from 0 to 3. The results were classified and Mann Whitney U test was used for comparison between groups. RESULTS The total incidence of bone marrow edema-like signal in amateur marathon group was 62%. Among them, the incidence of grade 1-3 was 48% (24/50), 12% (6/50), 2% (1/50), respectively, which was statistically significant compared with the controls (P = 0.007). There was no significant difference between gender before running (P = 0.172) and after running (P = 0.162). There was no significant difference before and after running (P > 0.05). However, 3 subjects showed new lesions, 8 subjects showed progression and 4 subjects showed decreased signal. CONCLUSION The occurrence of knee bone marrow edema-like signal in amateur marathon runners is more common. The lesions of bone marrow edema-like signal will show aggravation or improvement in a certain extent after the half marathon.

Abstract
The aim of this study was to investigate if frontal plane knee and hip control in single-leg squats or vertical drop jumps with an overhead target were associated with future non-contact anterior cruciate ligament (ACL) injury in elite female athletes. Of the 429 handball and 451 football athletes (age 21.5 ± 4.0 years, height 169.6 ± 6.4 cm, body weight 67.1 ± 8.0 kg), 722 non-injured and 56 non-contact ACL injured participants were eligible for analysis. We calculated lateral pelvic tilt, frontal plane knee projection angle, medial knee position, and side-to-side asymmetry in these from 2D videos recorded at baseline, and recorded any new ACL injuries prospectively. None of the aforementioned variables in either screening task were different or could discriminate between injured and non-injured athletes (all p values >.05 and Cohen's d values < .27). Two-dimensional video assessment of frontal plane knee and hip control during both a single-leg squat and vertical drop jump was unable to identify individuals at increased risk of non-contact ACL injury, thus should not be used for screening.

Abstract
INTRODUCTION Mountain running races have grown in popularity in the recent years. Nonetheless, there are few studies on injuries and injury rates. Moreover, these studies have focused on long-distance events such as ultramarathons (>42 km). Therefore, the aim of the present study was to examine the severity, type, and body location of musculoskeletal injuries during 20-42 km mountain running races. In addition, the injury rates in this type of races were examined. METHODS Data on injuries were collected during 36 mountain running races over 5 consecutive seasons from 2015 to 2019. The participants reported all musculoskeletal injuries on a standardized injury report form. The results were presented as the number of injuries per 1000 h exposure and per 1000 participants. RESULTS Twenty eight injuries were reported. Most injuries occurred in the ankle (32%) followed by the knee (14%) and foot/toe (11%). The number of injuries represented an overall injury rate of 1.6 injuries per 1000 h running and 5.9 injuries per 1000 runners. The case fatality rate was 0. CONCLUSIONS The incidence of musculoskeletal injuries during 20-42 km mountain running races is low. In addition, the majority of injuries experienced by runners are minor in nature and located in lower extremities, mainly the ankles.

Abstract
BACKGROUND Sports injuries are very common, and the management demands high degrees of skills and best techniques for an early return to play. The use of Platelet Rich Plasma (PRP) injections in the treatment of tendon, muscle and ligament injuries has become popular. This study observes the outcomes of PRP injections in sports injuries. METHODS Forty-eight athletes (mean age 29.93 ± 8.48, Male: 37, Female: 11) presenting to a sports medicine centre with different sports injuries with symptom duration (2.81 ± 1.94) months were given PRP injections (single or multiple) four weeks apart with maximum number of injections up to three depending upon the clinical condition, Pre and Post VAS scores. Specific rehabilitation program was administered and compliance was graded by Sports Injury Rehabilitation Adherence Scale (SIRAS). A 1 year follow-up of cases was done for assessing player satisfaction and return to play. RESULTS Pre-procedure (7.25 ± 0.70) and post-procedure (2.42 ± 0.74) VAS score for all athletes showed significant difference with a p value at 0.0001. The average number of injections was 1.35 ± 1.41 with 72.91% requiring only one injection while 18.75% and 8.33% required two and three injections, respectively. CONCLUSION Athletes who required a single injection for acute injuries of lower grade returned to sports activity earlier than those who required multiple injections for chronic injuries. PRP injection has optimal effects on sports injuries not responding to conservative management.

Abstract
Context: Surfer's myelopathy (SM) is an acute syndrome identified by nontraumatic paraparesis or paraplegia. Though traditionally tied to first-time surfers, the condition encompasses any activity involving hyperextension of the back such as gymnastics, yoga, and Pilates.Methods: MEDLINE® and Google Scholar literature searches were gathered to identify relevant case reports for determining the etiology, pathogenesis, evaluation, and management of SM.Results: While the rare nature of SM limits its full understanding, studies have pinpointed that hyperextension in the back leads to vasculature insufficiency secondary to dynamic compression of the artery of Adamkiewicz. In surfing, this hyperextension combined with the execution of the Valsalva maneuver while trying to stand up on the surfboard likely increases intraspinal pressure. Due to its nontraumatic origin, the presence of SM is not immediately clear. Moreover, its similarity in clinical and radiological presentations with other entities can further complicate diagnosis. Seemingly, idiopathic urological symptoms can be explained by the physician if they conduct a thorough history.Conclusion: In an effort to raise awareness for the practicing physician, we presently review the etiology, diagnosis, treatment, and prolonged effects of SM. With the surging popularity of surfing as well as the advent of children participating in precarious sports and activities at an earlier age, we can expect a rising incidence of traumatic and nontraumatic spinal cord injuries. Neurologists, urologists, emergency medicine and sports medicine physicians alike can utilize this review to build a high index of suspicion for SM. The risk factors for SM should be conveyed to those participating in novices in surfing, yoga, gymnastics, ballet, and any activity enabling sustained or repeated spinal extension. Increased general awareness will facilitate increased symptom recognition in order to arrest aggravation of injury.

Abstract
OBJECTIVES Stability of the core is associated with lower extremity functioning. Consequently, impaired core stability might play a role in developing non-contact acute lower extremity sports injuries. The objective was to investigate components of core stability as potential risk factors for acute lower extremity injuries. DESIGN A cohort study was set up with a follow-up and injury registration period of 1.5 years. PARTICIPANTS 142 male and female physical education students were included. MAIN OUTCOME MEASURES Measures of isometric hip and core muscular strength, endurance, proprioception and neuromuscular control of the core, and postural control were taken at the start of the study. Sports-related injury occurrence was registered during follow-up. RESULTS 27 (19%) injuries of interest occurred during follow-up. After multivariate model building, a significant predictive effect was found for side-to-side hip abduction strength asymmetry (p = .007). The hazard of developing an acute lower extremity injury increased with 6.2% with a 1 unit increase in side-to-side strength imbalance, regardless of gender. CONCLUSION Hip abduction strength imbalance was determined as a risk factor for the development of non-contact, acute lower extremity injuries. Normalizing hip strength imbalances might be beneficial for injury prevention. However, further research is needed to support this claim.

Abstract
An estimated 3.8 million traumatic brain injuries (TBI) occur each year, the majority classified as mild. Interest in models of mild and repeat mild TBI has grown due to reports of lasting morbidity following sports- or combat-related injury. There remains a paucity of data linking cellular or systems-related mechanisms to behavioral outcomes following repeat mild TBI, particularly in adolescent and adult rats. It is critical, therefore, to develop flexible models to evaluate which parameters of injury are associated with brain vulnerability or poor chronic outcome compared to normal recovery. While there are several existing models of repeat mild TBI in rodents, studying the effects of multiple hits has been complicated by the need for multiple survival surgeries, extensive pre-injury anesthesia time, and limitations due to animal skull thickness.•We developed a chronic "helmet" implant by combining aspects of the Impact Acceleration and Controlled Cortical Impact models.•Implants were performed days before injury, allowing us to decouple surgery from TBI. Critically, by pre-implanting the animals, only minimal anesthesia was required to position them under the impactor.•The implant allows for flexibility in the number and severity of injuries and interval between impacts.

Abstract
The purpose of this study is to investigate relationship between movement dysfunctions and sports injuries according to gender of youth soccer player. Thirty-eight middle school soccer players participated in this study and they were divided into male (n=19) and female (n=19) groups. The Functional Movement Screen (FMS) and the Quadriceps-angle (Q-angle) during single-leg squat were analyzed for identifying imbalance and asymmetry of the body, and sports injury questionnaire was examined for 6 months after FMS test. The number of sports injuries did not show significant difference between youth male and female soccer athletes. In FMS results, the scores of overhead squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, and rotary stability and the total scores were no significant differences between gender, but the score for the trunk stability push-up was significantly higher in male group than female group. There was no significant difference of Q-angle values between the left and right legs, but Q-angle value between youth male and female groups significantly showed interaction. Therefore, the present data suggested that FMS and Q-angle during single-leg squat might be indicators to predict and/or prevent sports injury in youth male and female soccer players.
