"I'd rather do that (Knee Control) than be injured and not able to play": a qualitative study on youth floorball players' and coaches' perspectives of how to overcome barriers for injury prevention exercise programme use.

This study explored youth floorball players' and coaches' perspectives on using the injury prevention exercise programmes (IPEPs) Knee Control or Knee Control+ (Knee Control programmes) and how to overcome barriers to programme use. We used a qualitative design with eight semistructured focus group discussions, six with players, 11-17 years old (n =42) and two with coaches (n =12). Data analysis followed the principles of qualitative content analysis. Three main categories emerged: challenges related to preventive training, promoting factors and solutions to facilitate the use of preventive training. To overcome barriers, players and coaches gave examples of how to tailor preventive programmes, such as adding joyful sport specific components. Player-perceived improved performance, with increased strength and speed from the preventive training, could be a promoting factor to increase motivation and enable IPEP use. Players and coaches offered examples of how to adapt and progress the preventive training by progressing gradually and choosing exercises that fit the team. Coaches emphasised that preventive training is important but difficult to prioritise in time-limited training sessions. Coaches' suggestions to overcome barriers were through collaboration and support from other coaches, to start using the IPEP at an early age, to keep it simple and motivating the players with, for example, positive role models. Players found the Knee Control exercises boring but necessary for injury prevention. Sometimes, coaches felt uncertain of their competence to use the Knee Control programmes and wished for support from the federation, club and other coaches. Players and coaches shared ideas on how to overcome barriers to IPEP use, such as to increase players' motivation, having a good structure, setting up routines for preventive training and to tailor the preventive training to the team. These findings can be used to further develop practical workshops and recommendations for programme use for players and coaches in youth team ball sports.

The Development and Execution of An Orthopaedic Sports Medicine Fellowship Surgical Skills Assessment.

BACKGROUND: Assessment of orthopaedic surgery trainees is traditionally based on subjective evaluation by faculty. The recent push for value-based health care has placed a premium on improving patient outcomes. As a result, surgical training evaluations for orthopaedic trainees are evolving to include more objective measures to evaluate competency. PURPOSE: To develop and subsequently demonstrate the efficacy of a novel surgical skills assessment for orthopaedic sports medicine fellows. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A team of 14 fellowship-trained orthopaedic sports medicine surgeons developed objective scoring rubrics for anterior cruciate ligament reconstruction (ACLR) and rotator cuff repair (RCR) using a modified Delphi process. Rubrics were designed based on 10 surgical steps with a grading scale (1-5) based on core competencies with a maximum summative score of 50. Fourteen orthopaedic fellows across a regionally diverse group of sports medicine-accredited fellowship programs were invited to complete both an ACLR and RCR in a surgical skills laboratory at the beginning and end of their fellowship year. Individual surgical steps, overall performance, and total procedure time were evaluated by a single sports medicine surgeon for both sessions. RESULTS: Thirteen of 14 fellows completed both pre- and post-fellowship assessments. For the ACLR procedure, the pre-fellowship mean summative score was 25.4 (SD, 4.4) and the post-fellowship mean summative score was 38.6 (SD, 4.1), which was a statistically significant improvement (P < .001). For the RCR procedure, the pre-fellowship mean summative score was 26.6 (SD, 5.4) and the post-fellowship mean summative score was 38.8 (SD, 4.3), which was also a statistically significant improvement (P < .001). The mean time to completion for the ACLR procedure was 82.3 minutes (SD, 4.3 minutes) pre-fellowship, which improved to 69.7 minutes (SD, 11.6 minutes) post-fellowship (P = .002). The mean time to completion for the RCR procedure was 85.5 minutes (SD, 5.0 minutes) pre-fellowship, which improved to 76.4 minutes (SD, 7.0 minutes) post-fellowship (P < .001). CONCLUSION: This surgical skills program represents the first standardized and reproducible instrument for the evaluation of 2 arthroscopic sports medicine procedures in the United States. Orthopaedic sports medicine fellows improved significantly in aggregate over their fellowship year with regard to the ACLR and RCR. The described program has the potential to serve as both a training tool and formal orthopaedic sports medicine fellow assessment.

Cuboid-navicular coalition in a female junior athlete.

Tarsal coalition is an uncommon cause of insidious-onset foot pain typically affecting adolescents. Cuboid-navicular coalitions are among the rarest variety, comprising less than 1% of all tarsal coalitions. This case report describes a female competitive gymnast in middle childhood with a 6-month history of worsening insidious onset right foot pain that forced withdrawal from all sporting activities. The patient reported a background of intermittent foot pain and bilateral ankle instability over the past 2 years. A comprehensive history and physical examination, alongside MRI, enabled the diagnosis of a fibro-osseous cuboid-navicular coalition. Through early diagnosis, a targeted and prompt trial of non-operative management was implemented, consisting of physiotherapy, a deloading protocol, orthotics and analgesia. At 6-month follow-up, this led to improvements in pain symptoms and functional outcomes as well as a return to competitive sport. Early recognition of cuboid-navicular coalition is essential to prevent early degenerative joint disease.

Understanding multicentric haemangioendothelioma: diagnostic dilemmas and treatment strategies.

Epithelioid haemangioendothelioma (EH) is a rare malignant vascular tumour occurring mainly in the liver and lungs, with bones being a rare site and primarily seen in the adult population. This case presents a male patient in his 40s who presented to the outpatient department with a chief issue of a painless swelling over the inguinal region for 4 months, gradually increasing in size, along with a history of a gradually enlarging, painless mass on his left knee over the past 5 years. Despite occasional discomfort during physical activities, the mass exhibited no associated trauma, fever, weight loss or systemic symptoms. Physical examination revealed a firm mass on the left knee and a matted lymph nodal swelling in the left inguinal region. Subsequent imaging studies identified multiple soft tissue lesions, osseous involvement and pulmonary metastases, suggestive of multicentric haemangioendothelioma. The patient underwent surgical excision of the inguinal mass and fixation of a pathological fracture in the left femur. He is currently undergoing chemotherapy and is scheduled for regular follow-up appointments. This case underscores the importance of thorough diagnostic evaluation and multidisciplinary management in complex oncological conditions like multicentric haemangioendothelioma.

Rising rates of anterior cruciate ligament reconstruction in Australian adults: An analysis of Australian Medicare Benefits Schedule database.

PURPOSE: Anterior cruciate ligament (ACL) reconstruction is an evolving field, though there remains sparse epidemiological data on the treatment of ACL ruptures. The objective of this study is to analyse the trends in the rate of ACL reconstruction (ACLR) in adult patients over the past two decades in the Australian population. METHODS: The incidence of ACLR between 2001 and 2020 in patients 15 years and over was analysed using the Australian Medicare Benefits Schedule (MBS) database. The data reflect patients with private health coverage (45% of the Australian population). An offset term was introduced using national population data to account for population changes over the study period. RESULTS: A total of 160,353 ACLRs were performed in Australia under the MBS in the 20-year period from 2001 to 2020. An annual increase in the total volume and per capita rate of ACLRs was found (p < 0.05). The annual volume of cases increased by 82%, from 5512 in 2001 to a peak of 10,011 in 2017. This increase was seen across all age groups (p < 0.05) and both sexes (p < 0.05), with a greater proportion of reconstructions performed on males (n = 102,357, 64%) than females (n = 57,996, 36%). In 2020, the rate of adult ACLRs decreased to a level last seen in 2004, likely due to the effects of COVID-19. CONCLUSIONS: The incidence of ACLR in adult patients has increased in Australia over the 20-year study period. The trends noted provide information that can be used to guide resource allocation and health provision in the future. LEVEL OF EVIDENCE: Level IV.

Surface electromyography of the vastus lateralis and gluteus medius muscles in post-operative T3-L3 hemilaminectomy dogs: a prospective controlled observational study.

Objective: The objective of this study was to determine if surface electromyography (sEMG) demonstrates differences in muscle activation between normal and dogs recovering from spinal cord injury due to intervertebral disk extrusion. Animals: Two groups of client-owned small-breed chondrodysplastic-type dogs were tested. Group 1 consisted of seven ambulatory paraparetic dogs that had undergone a hemilaminectomy procedure in the T3-L3 region for intervertebral disk extrusion 1 month prior. Group 2 was made up of seven normal dogs that had no history of intervertebral disk disease or spinal surgery. Procedures: Each subject walked 10 feet on a nonslip surface for at least five gait cycles for the sEMG to capture muscle activation of the vastus lateralis and gluteus medius, bilaterally. Muscle activation was quantified as the total myoelectric output area under the curve, averaged across all gait cycles. Results: Muscle activation was significantly greater in the post-operative hemilaminectomy group (p = 0.012). There was a significant difference in muscle activation between each hindlimb in the post-operative hemilaminectomy group, but not in the normal group. The muscle activation was significantly lower on the side that underwent surgery compared to the opposite limb (p = 0.0034). Conclusion and clinical importance: Post-operative hemilaminectomy dogs have greater hindlimb muscle activation compared to normal dogs, which likely represents a lack of descending inhibition secondary to upper motor neuron syndrome. The side of surgery is correlated with decreased muscle activation. Surface EMG can be used to evaluate muscle activity in dogs recovering from spinal decompression surgery.

Ankle, knee and concussion concerns: Unveiling injury patterns in highly trained South African netball players.

OBJECTIVES: To describe the rate and type of netball injuries sustained during women's university-level tournament matches in South Africa. DESIGN: Descriptive epidemiological study. SETTING: Three editions of the women's Varsity Netball tournament (2021-23). PARTICIPANTS: Student-athletes representing nine university women's teams. MAIN OUTCOME MEASURES: Medical attention match injuries prospectively recorded by team medical staff. Injuries were classified according to the 2020 consensus statement, with the addition of "concussion" as a separate pathology type. The main outcomes are reported as incidence (injuries per 1000h; 95% confidence intervals - CIs), burden (days lost per 1000h; 95%CIs), and frequency (% of all injuries). RESULTS: Sixty-three injuries were recorded from 48 different players (58.8 per 1000h; 45.2-75.3) and the overall injury burden was 401 days per 1000h (364-440). Injury incidence by pathology type was highest for joint sprains (28.9 per 1000h), tendinopathies (7.5 per 1000h), and concussions (4.7 per 1000h). Joint sprains to the ankle accounted for 49% of the overall estimated days lost. CONCLUSIONS: Ankle joint sprains should be the primary target of injury risk reduction programmes in highly trained netball players. Concussions were reported and efforts should be made to increase awareness among players, coaches and medical staff.

Sport PRactice and its Effects on aortic size and valve function in bicuspid Aortic valve Disease: a cross-sectional report from the SPREAD study.

OBJECTIVE: Concerns exist about the possible detrimental effects of exercise training on aortic size and valve function in individuals with bicuspid aortic valve (BAV). This multicentre international study aimed to determine the characteristics of aortic size and valve function in athletes versus non-athletes with BAV and athletes with tricuspid aortic valve (TAV). METHODS: We enrolled competitive athletes with BAV and age- and sex-matched athletes with TAV and non-athletes with BAV. We assessed valve function, aortic size and biventricular measures using echocardiography. Individuals with established moderate-severe AV stenosis, regurgitation or significant aortic dilation were excluded from the study. RESULTS: The study population comprised 504 participants: 186 competitive athletes with BAV (84% males; age 30±11 years), 193 competitive athletes with TAV and 125 non-athletes with BAV. The aortic annulus was greater in athletes with BAV than athletes with TAV and non-athletes with BAV (p<0.001). Both athletic and non-athletic individuals with BAV had greater sinuses of Valsalva, sino-tubular junction and ascending aorta diameters than athletes with TAV (p<0.001). However, no significant differences were found between athletes and non-athletes with BAV. Left ventricular index volumes and mass were greater in athletes with BAV than in the other two groups (p<0.001). Individuals with BAV (athletes and non-athletes) had greater mean gradients than TAV athletes. CONCLUSION: This multicentre international study demonstrates no differences between athletes with BAV and non-athletes with BAV regarding aortic valve function or aortic dimensions. However, athletes with BAV have larger aortic diameters and a relatively worse valvular function than athletes with TAV.

Pediatric Concussions in Contact Sports: A 10-Year Retrospective Analysis of Mechanisms and Associated Symptoms.

Background: Concussions make up a significant proportion of sports injuries. This study aimed to describe the mechanisms of injury and associated symptoms of pediatric patients diagnosed with concussions (age range, 4-17 years) from contact sports. Hypothesis: Mechanisms of injury would differ based on sex and age, with female athletes and younger athletes aged 4 to 11 years sustaining fewer concussions from player-to-player contact. Study Design: Descriptive epidemiology study. Methods: The National Electronic Injury Surveillance System was queried for all contact sport concussions presented to United States emergency departments. The sports analyzed included basketball, football, soccer, hockey, rugby, and lacrosse. Descriptive data, mechanisms of injury, and associated symptoms were analyzed for each sport. Differences in the number of concussions sustained by year and sport, the severity of the injury, and associated symptoms were compared using chi-square test, and differences in proportion were calculated for mechanisms of injury stratified by sex and age. Results: A total of 12,602 youth athletes sustained concussions between 2012 and 2021. Most patients were male (78.5%), with a mean age of 13.48 years. Football concussions were the most common, with 45.32% of the concussions. The mechanism of injury was largely sport-specific, with player-to-player contact the most common overall. Older male athletes were more likely to have concussions from player-to-player contact, whereas younger athletes were more impacted by head-to-ground mechanisms. Symptom presentation was not sport-specific, and headache and dizziness were the most common presentation at 41.2% and 26.2%, respectively. Conclusion: The most important overall mechanism of injury was player-to-player contact, especially in older male youth athletes, whereas younger athletes were more likely to be concussed due to head-to-ground injuries.

Open Capsular Repair with Dermal allograft and tarsal tunnel release in the treatment of Tarsal Tunnel Syndrome in a Young Collegiate Athlete: A Case Report.

Tarsal tunnel syndrome is an entrapment neuropathy of the posterior tibial nerve beneath the flexor retinaculum that can be precipitated by either intrinsic or extrinsic factors. We report a unique case of a posterior medial ankle joint capsular defect with localized fluid extravasation between the flexor digitorum longus and flexor hallucis longus leading to symptoms consistent with tarsal tunnel syndrome in a collegiate tennis player. This patient is a 19-year-old female with no past medical history who presented with symptoms consistent with tarsal tunnel syndrome. After confirmation with magnetic resonance imaging, the patient underwent capsular reconstruction with dermal allograft in combination with a tarsal tunnel release. The patient had improvement in pain and recovery of paresthesia 3 months postoperatively. At the latest follow-up of 1 year postoperatively, the patient has not had a recurrence of symptoms and has returned to the same level of competitive play. Many different causes of tarsal tunnel syndrome are described in the literature, but to our knowledge, there is no current literature that describes a defect in the tibiotalar joint capsule as a cause of tarsal tunnel syndrome.

High prevalence of harmful drinking habits and gambling among professional rugby players: mental health symptoms and lifestyle risks among New Zealand Super Rugby players-a cross-sectional survey.

Objectives: Determining the prevalence of mental health and lifestyle risk factors (smoking, alcohol consumption, recreational drug use, gambling, family violence and anger management) in New Zealand (NZ) male professional rugby players. Study design: Cross-sectional survey of mental health symptoms and lifestyle risk factors in male professional rugby players in NZ. Methods: Players from all five NZ men's Super Rugby Franchises were invited to complete an online questionnaire (SportCHAT) measuring demographic status and mental health symptoms. Descriptive and interferential statistical analyses were used to identify the most prevalent mental health and lifestyle risk factors. Results: 105 players participated in the study (response rate 52.5%). 51.4% of players were either at moderate or high risk for alcohol-related harm (defined as potential health, social, legal or financial problems linked to alcohol consumption). In comparison, 4.8% reported recreational drug use and 5% reported smoking tobacco. Twenty players (19%) reported engaging in gambling, with five of these reporting problematic gambling. 21% of players reported symptoms of depression, but none reached the 'mild depression' threshold of the Patient Health Questionnaire for Depression. Younger players (aged 20-29) were more likely to report symptoms of depression than older players (aged 30-39). The prevalence of anxiety symptoms was 17.1%. 66.7% of these players reported minimal symptoms (GAD-7 score 0-4) and 33.3% reported mild symptoms (GAD-7 score 5-9). Family violence was reported by 2.9% of respondents, while 12.4% reported issues with anger management. There were no significant differences between ethnic groups. Conclusion: There is a higher prevalence of alcohol misuse and gambling, but lower reported rates of depression and anxiety symptoms in this cohort when compared with the general population.

Lower extremity return to sport testing: A systematic review.

BACKGROUND: Lower extremity injuries account for an enormous portion of sports medicine cases in the United States each year. Unfortunately, there are no uniform criteria for athletes to complete prior to returning to sport (RTS) following a lower extremity injury. Therefore, the purpose of this systematic review is to review current literature for joint-specific and global lower extremity testing to determine the most valid functional test that can be utilized to reduce the risk of re-injury as athletes RTS. METHODS: A systematic search of PubMed, PubMed Central, Cochrane Library, OVID, and Embase databases was conducted for studies prior to May 2024 following PRISMA guidelines. ROBINS-I Tool was utilized for the risk of bias assessment. RESULTS: Of 19,189 studies, 114 (0.6%) studies published prior to May of 2024 met inclusion criteria and were analyzed. Eighty five percent of articles discussed RTS for individuals with knee pathology. Furthermore, 82% specifically analyzed RTS following ACL reconstruction. The most common RTS test was isokinetic dynamometry testing which is seen in 73% of studies. Only 6.2% of studies analyzed RTS for individuals with hip pathology and only two studies analyzed RTS for patients with ankle injuries. CONCLUSION: Even with the enormous amount of literature that exists regarding ACL injuries and testing there is no standardized criterion for RTS clearance. The suggested test batteries from this review can serve as a framework for future research and validation for joint-specific RTS functional testing.

Application of the IOC Relative Energy Deficiency in Sport (REDs) Clinical Assessment Tool version 2 (CAT2) across 200+ elite athletes.

OBJECTIVE: This cross-sectional retrospective and prospective study implemented the 2023 International Olympic Committee Relative Energy Deficiency in Sport (REDs) Clinical Assessment Tool version 2 (CAT2) to determine the current severity of REDs (primary outcome) and future risk of bone stress injuries (BSI, exploratory outcome) in elite athletes. METHODS: Female (n=143; 23.3±4.3 years) and male (n=70; 23.1±3.7 years) athletes (performance tier 3 (52%), tier 4 (36%), tier 5 (12%)) participated in a baseline CAT2 (with minor modifications) assessment, including a self-report questionnaire (menstrual function (females), BSI, Eating Disorder Examination Questionnaire (EDE-Q)), bone mineral density (BMD via DXA) and fasted blood analysis (triiodothyronine (T3), testosterone, cholesterol). Athletes were assigned a green, yellow, orange or red light via CAT2. The prospective risk of new self-report of physician-diagnosed BSI was assessed over a subsequent 6-24 months. RESULTS: REDs prevalence was 55% green, 36% yellow, 5% orange and 4% red light. The CAT2 identified a greater prevalence of amenorrhoea and BSI and lower T3, testosterone and BMD (p<0.01) in red, orange and yellow (those with REDs) versus green light. ORs for a prospective self-reported BSI (majority physician diagnosed) were greater in orange vs green (OR 7.71, 95% CI (1.26 to 39.83)), in females with severe amenorrhoea (OR 4.6 (95% CI 0.98 to 17.85)), in males with low sex drive (OR 16.0 (95% CI 4.79 to 1038.87)), and athletes with elevated EDE-Q global scores (OR 1.45 (95% CI 0.97 to 1.97)). CONCLUSION: The CAT2 has high validity in demonstrating current severity of REDs, with increased future risk of self-reported BSI in athletes with a more severe REDs traffic light category.

The 25 Most Cited Articles in Pediatric Orthopaedic Sports Medicine.

Background: Citation analysis reflects the influence a work has on a field of research and can be used to identify "classic" works and their qualities in medical specialties. By analyzing the characteristics of these works, we intended to determine what qualities make for a highly cited work in pediatric orthopaedic sports medicine. Purpose: To identify the top 25 most cited articles in the field of pediatric orthopaedic sports medicine. Study Design: Cross-sectional study. Methods: The Science Citation Index Expanded feature within the Web of Science database was searched using a Boolean string, generating 2008 pediatric orthopaedic sports medicine articles arranged by number of citations. The top 25 most cited articles were reviewed for authors, year of publication, source journal, country of origin, region of origin, diagnosis or condition of focus, and level of evidence (LOE). Results: Most of the articles were published in the 2000s (range, 1992-2016). The mean number of citations was 166 (range, 119-329), and the mean citation density was 13.25 (range, 4.25-29.57). There were 18 of 25 studies performed in the United States. A plurality of the articles were published in the American Journal of Sports Medicine. The LOE ranged from 2 to 4, with the most common being level 2 (11/25). Anterior cruciate ligament (ACL) injury management (14/25) and epidemiological studies on the incidence of various sports injuries (6/25) were the most represented topics of study. Since the 1990s, the mean citation density for articles related to ACL injuries in young athletes and the epidemiology of sports injuries has been increasing. Conclusion: This evaluation demonstrated that ACL injuries and the epidemiology of sports injuries had the highest citation density of the most influential studies in pediatric orthopaedic sports medicine. We identified attributes such as country of publication, journal of publication, and LOE that make for a highly cited pediatric orthopaedic sports medicine article. Overall, citation density in pediatric sports medicine is increasing. Nonetheless, the most represented LOE in the most cited works is level 2, with no level 1 studies being represented in the top 25. In terms of both topics and LOE, this study allows surgeons to identify deficiencies in the existing literature and meaningfully design future studies to improve on these.

Does lower extremity stiffness influence change of direction speed in badminton athletes after dynamic loaded warm-up?

This study investigated whether lower extremity stiffness plays a role in the enhancement of change of direction speed (CODS) and the duration of this enhancement after dynamic loaded warm-up (DLWU). Fifteen badminton athletes underwent DLWU, and CODS, individual muscle and tendon stiffness, and vertical stiffness were measured before DLWU and 6, 12, and 18 min after DLWU. The data were analyzed using ANOVA and covariance analysis. Significant improvements in CODS were found at 6, 12, and 18 min post-DLWU compared to pre-DLWU (p < 0.05). The Achilles tendon stiffness of the dominant leg increased at 6 min (p = 0.039) and 18 min (p = 0.024) post-DLWU compared to pre-DLWU. Achilles tendon stiffness of the dominant leg had a significant effect on improving CODS (p > 0.05). CODS improvement lasted up to 18 min after DLWU in badminton athletes, potentially related to increased Achilles tendon stiffness of the dominant leg.

Foot and Ankle MRI Findings in Asymptomatic Professional Ballet Dancers.

Background: Previous research in sport populations has demonstrated that abnormal magnetic resonance imaging (MRI) findings may be present in individuals without symptoms or known pathology. Extending this understanding to ballet, particularly in relation to the foot and ankle, is important to guide medical advice given to dancers. Purpose: To assess foot and ankle MRI scans in asymptomatic ballet dancers focusing on bone marrow edema and the posterior ankle and to investigate whether these MRI findings would become symptomatic within 1 year. Study Design: Case series; Level of evidence, 4. Methods: In total, 31 healthy dancers (62 feet/ankles; 15 male and 16 female; age, 26.5 ± 4.3 years) who were dancing in full capacity were recruited from an elite professional ballet company. Orthogonal 3-plane short tau inversion recovery imaging of both feet and ankles was obtained using 3T MRI and the images were reviewed using a standardized evaluation form by 2 musculoskeletal radiologists. Injuries in the company were recorded and positive MRI findings were assessed for correlation with any injuries requiring medical attention during the subsequent 12 months. Results: A total of 51 (82%) of the 62 feet and ankles had ≥1 area of bone marrow edema. The most common locations of bone marrow edema were the talus (n = 41; 66%), followed by first metatarsal (n = 14; 23%). Os trigonum and Stieda process were seen in 5 (8%) and 8 (13%) ankles, respectively. Among them, 2 os trigona showed bone marrow edema. Fluid in the anterior and posterior talocrural joints and the subtalar joint was observed in 48%, 63%, and 63% of these joints, respectively. Fluid around foot and ankle tendons was observed, with the most prevalent being the flexor hallucis longus tendon (n = 13; 21%). Two dancers who had positive findings on their MRI subsequently developed symptoms during the next 12 months. Conclusion: Positive MRI findings are commonplace in the foot and ankle of asymptomatic professional ballet dancers. The majority do not result in the development of symptoms requiring medical attention within 12 months. Careful interpretation of MRI findings with the dancer's clinical picture is required before recommending activity modification or further intervention.

Twenty-first century knowledge mapping on oral diseases and physical activity/exercise, trends, gaps, and future perspectives: a bibliometric review.

Maintenance and improvement of an individual's overall well-being require a multidisciplinary approach that encompasses everything from oral health care to regular physical exercise. The notion that poor oral health can influence general health and athletic performance has sparked an interest in this relationship. This study offers an overview of relevant research and a knowledge map,and discusses publication metrics and key topics concerning the relationship between physical activity or exercise and oral diseases. We searched the Web of Science database for articles published in the 21st century that addressed the relationship between physical activity and oral diseases. Under the stipulated inclusion criteria, a rigorous selection process yielded 276 from 3,883 retrieved articles. The articles were classified by what was assessed as follows: occurrence of oral diseases in athletes or sports enthusiasts (n = 174); impact of physical activity or exercise on the oral cavity (n = 59); effects of oral changes on sports performance and physical fitness (n = 31); and the connection between oral health status, physical activity or exercise, and systemic conditions (n = 12). Orofacial trauma has received the most attention among all investigated oral diseases. However, there is a need for greater attention of dysfunctional habits that can contribute to premature tooth wear, as well as oral inflammatory diseases that can have systemic implications. This mapping can encourage the development of new primary research.

What the Paris 1924 olympics tell us about promoting oral health for community sport - a call to action.

Sport participation has huge benefits to individuals and communities including both physical health and wellbeing, prevention of non-communicable diseases, promoting equity and reducing inequalities. Sport participation can disadvantage oral health with a life-long shadow of treatment need and potential psycho-social consequences, despite these problems being preventable. It is therefore a priority to collaborate with partners in community sport to embed oral health promotion as one of the foundations of overall health in order to gain the most equitable and sustainable benefits from sport participation.

What's in a Name? Defining 'Failure' in Anterior Cruciate Ligament Reconstruction Randomized Controlled Trials: A Systematic Review.

PURPOSE OF REVIEW: Graft failure, one of the most common outcomes in anterior cruciate ligament reconstruction randomized controlled trials, lacks a consensus definition. The purpose of this study was to systematically summarize current practice and parameters in defining anterior cruciate ligament reconstruction graft 'failure'. RECENT FINDINGS: Forty studies (4466 participants) satisfied the inclusion criteria. Of these, 90% either defined failure formally or referenced the etiology of failure, the remaining 10% used the term failure without referencing the anterior cruciate ligament reconstruction graft. Among the included studies, there was a high level of inconsistency between the definitions of graft failure. The extracted data was categorized into broader groups, revealing abnormal knee laxity (80%) and graft re-rupture (37.5%) as the most common parameters incorporated in the definitions of graft failure in high-level randomized controlled trials. This review shows that anterior cruciate ligament reconstruction randomized controlled trials lack a consistent definition for graft failure. A universal definition is vital for clarity in medical practice and research, ideally incorporating both objective (e.g. graft re-rupture) and subjective (e.g. validated questionnaires) parameters. A composite outcome should be established which includes some of the common parameters highlighted in this review. In the future, this review can be used to assist orthopaedic surgeons to establish a formal definition of anterior cruciate ligament reconstruction graft 'failure'.

Factors affecting maximal oxygen uptake in prepubertal children: a systematic review and meta-analysis.

In pre-pubertal children the factors affecting maximal oxygen uptake have yet to be fully understood. Therefore, the purpose of this analysis is to present cardiorespiratory fitness in prepubertal boys and girls and to determine if there are any differences based on sex, exercise testing modality or if maximal or peak oxygen consumption metrics are used. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed. For statistical analysis, multilevel models grounded in Bayesian principles were used. Selected studies obtained: maximal effort during the test, peak or maximal oxygen consumption (V̇O2) values, boys and girls (sex specific groups only) age under 11, cycle ergometry or treadmill, pre-intervention or no intervention data. In boys using cycle ergometry, 118 studies were included in the analysis, in boys using treadmill 115, in girls using cycle ergometry 83 and in girls using treadmill testing 95 study entries were included. As children get older, their cardiorespiratory fitness increases (P ≈ 100%). Studies with participants having smaller body mass have higher V̇O2 relative to body mass values (P ≈ 100%). Boys have higher V̇O2 values than girls (P ≈ 100%). Studies using treadmill reported higher values than those using cycle ergometer (P ≈ 100%). Regarding the influence of measurement method (max vs. peak) on V̇O2 values we did not find significant differences. In conclusion, we present reference values for cardiorespiratory fitness in prepubertal boys and girls using cycle ergometry or treadmill. Prepubertal boys have higher cardiorespiratory fitness than girls and using treadmill testing might be a preferred method to cycle ergometry, especially in older children. Maximal or peak oxygen consumption metrics might be used interchangeably in prepubertal children.
