Purpose: Midportion Achilles tendinopathy is a relatively common condition. This study aimed to investigate the presence of a normal Achilles tendon, but a tendinopathic plantaris tendon, in a large and consecutive prospective sample of patients referred to a specialised tendon clinic for midportion Achilles tendon pain not responding to non-surgical treatment. Patients and Methods: A total of 105 consecutive tendons were operated on in 81 patients (62 males) suffering from painful midportion Achilles tendon pain. Clinical examination, ultrasound (US) and colour Doppler (CD) examination, and wide awake local anaesthetic no tourniquet (WALANT) surgery were performed in all patients. Results: For 19/105 (18%) tendons from 14 patients, clinical examination suspected plantaris tendinopathy alone as there was a distinct tenderness on the medial side, but no thickening of the Achilles tendon. US examination followed by surgery confirmed the diagnosis. Conclusion: Midportion Achilles tendon pain is not always related to Achilles tendinopathy since pain related to the plantaris tendon alone was found in almost every fifth patient. Consequently, there is an obvious need for proper examination to identify the pain source and establish a correct diagnosis before treatment.

Abstract: Failure rates among primary Anterior Cruciate Ligament Reconstruction (ACLR) range from 3.2% to 11.1%. Recently, there has been increased focus on surgical and anatomic considerations which predispose patients to failure, including excessive posterior tibial slope (PTS), unaddressed high-grade pivot shift, and improper tunnel placement. The purpose of this review was to provide a current summary and analysis of the literature regarding patient-related and technical factors surrounding revision ACLR, rehabilitation considerations, overall outcomes and return to sport (RTS) for patients who undergo revision ACLR. There is a convincingly higher re-tear and revision rate in patients who undergo ACLR with allograft than autograft, especially amongst the young, athletic population. Unrecognized Posterior Cruciate Ligament (PLC) injury is a common cause of ACLR failure and current literature suggests concurrent operative management of high-grade PLC injuries. Given the high rates of revision surgery in young active patients who return to pivoting sports, the authors recommend strong consideration of a combined ACLR + Anterolateral Ligament (ALL) or Lateral extra-articular tenodesis (LET) procedure in this population. Excessive PTS has been identified as an independent risk factor for ACL graft failure. Careful consideration of patient-specific factors such as age and activity level may influence the success of ACL reconstruction. Additional technical considerations including graft choice and fixation method, tunnel position, evaluation of concomitant posterolateral corner and high-grade pivot shift injuries, and the role of excessive posterior tibial slope may play a significant role in preventing failure.

Objective: Social distancing protocols due to the COVID-19 pandemic resulted in premature ending of athletic seasons and cancellation of upcoming seasons, placing significant stress on young athletes. Inability to play or forced early retirement has significant consequences on athlete’s mental health, as demonstrated by an extensive body of injury literature. We hypothesize that premature suspension and cancellation of athletic events due to the COVID-19 pandemic leads to higher incidence of depressive symptoms among high-school and collegiate athletes. Further, athletes who strongly derive their sense of self-worth centered around athletics would have higher rates of depressive symptoms. Methods: High school and collegiate athletes were evaluated for depressive symptoms, emotional health and athletic identity measures through validated assessment instruments from May 2020 through July 2020. The Patient-Reported Outcomes Measurement Information System Depression Computer Adaptive Test (PROMIS-10 Depression CAT), Veterans RAND-12 (VR-12), which comprises both a physical and mental health component, and Athletic Identity Measurement Scale (AIMS) were utilized. Results: Mental health assessments were completed by 515 athletes (52.4% male, 47.6% female; .84.5% collegiate, 15.5% high school). Female athletes scored significantly worse than males on VR-12 mental health assessments, as well as PROMIS-10 Depression scores; however, males scored significantly lower than females on VR-12 physical health assessments, irrespective of education level. Athletes who had strong associations with athletics as central to their personal identity exhibited worse psychologic impact on VR-12 mental health and PROMIS-10 Depression measures and female athletes in this cohort reported greater depressive symptoms than males. Conclusion: Social distancing protocols due to the COVID-19 pandemic have limited athlete’s ability to participate in sports at the training and competition level. Higher rates of depressive symptoms in high school and college athletes have resulted among female athletes and those who identify strongly as an athlete.

Purpose: Endurance sports performance is influenced by several factors, including maximal oxygen uptake (⩒O2max), the percentage of ⩒O2max that can be sustained in endurance events, running economy, and body composition. Traditionally, ⩒O2max can be measured as an absolute value, adjusted for body mass, reflecting the athlete’s central capacity (maximal cardiac output), or adjusted for lean mass (LM), reflecting the athlete’s peripheral capacity (muscular oxidative capacity). The present study aims to evaluate absolute, total body mass, and lower limb LM-adjusted ⩒O2max, ventilatory thresholds (VT), respiratory compensation points (RCP), and body composition during two training periods separated by 8 months. Patients and Methods: Thirteen competitive amateur triathletes [seven men (40.7± 13.7 years old, 76.3± 8.3kg, and 173.9± 4.8cm) and six women (43.5± 6.9 years old, 55.0± 2.7kg, 164.9± 5.2cm)] were evaluated for body composition with dual-energy X-ray absorptiometry and ⩒O2max, VT, RPC, and maximal aerobic speed (MAS) with a cardiorespiratory maximal treadmill test. Results: The absolute ⩒O2max (p = 0.003, d = 1.05), body mass–adjusted ⩒O2max (p < 0.001, d = 1.2859), and MAS (p = 0.047, d = 0.6139) values differed significantly across evaluation periods. Lower limb LM–adjusted ⩒O2max (p = 0.083, d = − 0.0418), %⩒O2max at VT (p = 0.541, d = − 0.1746), speed at VT (p = 0.337, d = − 0.2774), % ⩒O2max at RCP (p = 0.776, d = 0.0806), and speed at RCP (p = 0.436, d = 0.2234) showed no difference. Conclusion: The sensitivities of ⩒O2max adjusted for body mass and ⩒O2max adjusted for LM to detect changes in physical training state differ. Furthermore, decreases in physical fitness level, as evaluated by ⩒O2max values, are not accompanied by changes in VT.

Objective: Lower extremity ankle and knee injuries occur at a high rate in the National Basketball Association (NBA) often requiring surgical intervention. This study aimed to identify surgical rates and risk factors for surgical intervention using multivariate analysis in ankle and knee injuries in NBA player.
Methods: Player demographics, performance metrics, advanced statistics, and injury characteristics were recorded using publicly available data. To standardize injury events over multiple years, injury events per 1000 athlete exposure events (AE, one player participating in one game) were calculated. Descriptive analysis and multivariate logistic regression were completed to find associations with surgical intervention in ankle and knee injuries.
Results: A total of 1153 ankle and knee injuries were included in the analysis with 73 (6.33%) lower extremity injuries treated with surgery. Knee injuries had a higher incidence of surgical intervention (0.23 AE) than ankle injuries (0.04 AE). The most frequent surgical knee injury was meniscus tear treated with meniscus repair (0.05 AE) and the most frequent ankle surgery was surgical debridement (0.01 AE) Multivariate logistic regression indicated lower extremity injuries that required surgery were associated with more minutes per game played (odds ratio [OR] 1.13; p = 0.02), a greater usage rate (OR 1.02 p < 0.001), the center position (OR 1.64; 95% [CI] 1.2-2.24; p = 0.002) and lower player efficiency rating (OR 0.96; 95% p < 0.001).
Conclusion: Knee surgery was significantly more frequent than ankle surgery despite similar injury rates per 1000 exposures. The center position had the greatest risk for lower extremity injury followed by minutes played while a higher player efficiency rating was protective against surgical intervention. Developing strategies to address these factors will help in the management and prevention of lower extremity injuries requiring surgical intervention.
目的：在美国国家篮球协会（NBA）中，下肢踝关节和膝关节损伤的发生率很高，通常需要手术治疗。本研究旨在通过多变量分析确定 NBA 球员踝关节和膝关节损伤的手术率和手术干预的风险因素：利用公开数据记录了球员的人口统计学特征、表现指标、高级统计数据和损伤特征。为了将多年来的受伤事件标准化，计算了每 1000 个运动员暴露事件（AE，一名球员参加一场比赛）中的受伤事件。研究人员完成了描述性分析和多变量逻辑回归，以发现踝关节和膝关节损伤与手术干预之间的关联：共有 1153 例踝关节和膝关节损伤纳入分析，其中 73 例（6.33%）下肢损伤接受了手术治疗。膝关节损伤的手术干预发生率（0.23 AE）高于踝关节损伤（0.04 AE）。最常见的手术治疗膝关节损伤是半月板撕裂并进行半月板修复（0.05 AE），最常见的踝关节手术是手术清创（0.01 AE）。 多变量逻辑回归表明，需要手术治疗的下肢损伤与每场比赛出场时间较长有关（几率比 [OR] 1.13; p = 0.02）、更高的使用率（OR 1.02 p < 0.001）、中锋位置（OR 1.64; 95% [CI] 1.2-2.24; p = 0.002）和更低的球员效率等级（OR 0.96; 95% p < 0.001）：结论：尽管每 1000 次暴露中的受伤率相似，但膝关节手术的频率明显高于踝关节手术。中锋位置的球员下肢受伤的风险最大，其次是出场时间，而球员效率等级越高，手术干预的风险越低。针对这些因素制定策略将有助于管理和预防需要手术治疗的下肢损伤。

Aim: Although it has been previously observed that sedentary behavior (SB) was not related to training duration in marathon runners, little information existed about the relationship of SB with training, anthropometric and physiological characteristics in this population. This study aimed to investigate the prevalence of SB and its correlation with performance parameters (such as body fat percentage, maximal oxygen uptake and weekly training volume) as well as its variation by sex and day (ie, weekdays versus weekend) in recreational marathon runners. Methods: A total of 151 finishers (women, n = 29; men, n = 122; age 43.1 (8.7) years, mean (standard deviation)) in the Athens marathon 2017 performed a series of anthropometric and physiological tests, and completed the Multi-context sitting time questionnaire. Results: SB did not correlate with anthropometric and physiological characteristics and no difference in these characteristics was shown between low and high sedentary participants (p > 0.05). SB did not differ between women and men (p > 0.05), but differed between working and non-working days (p < 0.05). Conclusion: In contrast to previous findings on the general population indicating an association of a high SB with a low cardiorespiratory and muscular fitness, our finding of no correlation between SB and physical fitness in marathon runners suggested that endurance exercise might offset the negative effects of SB.

Abstract: Stress fractures of the first rib are uncommon and thought to be associated with overhead-throwing athletes. Soft tennis is similar to regular tennis but uses a much softer rubber ball. In the current report, a 14-year-old girl suffered from shoulder girdle pain, especially at the end of her tennis ground stroke. Plain radiographs showed overgrowth of bone with a fracture line on the first rib, and a diagnosis of stress fracture was made. She was advised to amend her stroke form to reduce force to the shoulder and was able to continue sports activity without pain 10 months after the appearance of her symptoms and before confirmation of bone healing. The current case is not associated with overhead-throwing, but possibly with repetitive exercises of her tennis ground strokes. Conservative medical follow-up with proper sport-specific professional advice allows continuation of the sport.
Plain Language Summary: Stress fractures of the first rib are rare, mainly linked to overhead-throwing athletes. Soft tennis resembles regular tennis but uses a softer rubber ball. In this case, a 14-year-old girl with shoulder girdle pain, especially during tennis strokes, was diagnosed with a first rib stress fracture via plain radiographs. She improved by adjusting her stroke and resumed sports pain-free within 10 months, even before full bone healing. This case was not linked to overhead-throwing but potentially resulted from repetitive ground strokes. Proper medical guidance supports sport continuation.

She was advised to amend her stroke form to reduce force to the shoulder and was able to continue sports activity without pain 10 months after the appearance of her symptoms and before confirmation of bone healing. The current case is not associated with overhead-throwing, but possibly with repetitive exercises of her tennis ground strokes. Conservative medical follow-up with proper sport-specific professional advice allows continuation of the sport.<br/><br/><strong>Plain Language Summary:</strong> Stress fractures of the first rib are rare, mainly linked to overhead-throwing athletes. Soft tennis resembles regular tennis but uses a softer rubber ball. In this case, a 14-year-old girl with shoulder girdle pain, especially during tennis strokes, was diagnosed with a first rib stress fracture via plain radiographs. She improved by adjusting her stroke and resumed sports pain-free within 10 months, even before full bone healing. This case was not linked to overhead-throwing but potentially resulted from repetitive ground strokes. Proper medical guidance supports sport continuation.<br/><br/><strong>Keywords:</strong> first rib, stress fracture, tennis, tennis stroke<br/>","PeriodicalId":51644,"journal":{"name":"Open Access Journal of Sports Medicine","volume":"4 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139051971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose: The Athlete Sleep Behavior Questionnaire (ASBQ) is an 18-item self-reported questionnaire that can be used to screen for sleep disorders in athletes and assess environmental, behavioral, and sports-related factors along with sleep disorders. This study aimed to analyze the reliability and validity of the ASBQ translated into Japanese (ASBQ-J).
Patients and methods: 111 female collegiate athletes completed both the initial test and retest. Independent variables were what kind of sports they perform, level as an athlete, grade (freshman, sophomore, junior, senior), and age. The reliability of the survey was assessed using Cronbach's alpha and intraclass correlation, and Pearson's correlation coefficient was calculated to determine the correlation between the total ASBQ scores and three components which were routine/environmental, behavioral, and sports factors.
Results: A total of 37.8% of athletes had ASBQ scores equal or less than 36 indicating good sleep. However, 19.8% of athletes scored more than 42, indicating poor sleep. Cronbach alpha was 0.62 and 0.65 for test and retest, respectively. Intraclass correlation was 0.78 (P < 0.01), indicating sufficient internal consistency and test-retest validity. Mean ASBQ scores were 38.5 ± 5.0 and 37.0 ± 6.5 for test and retest, respectively, and it was not significantly different between the two groups (P = 0.37). The correlation coefficients between the ASBQ-J and component scores were all statistically significant (all P < 0.01).
Conclusion: ASBQ-J is a reliable questionnaire for assessing sleep disorders in athletes whose primary language is Japanese.

Purpose: The SpeedCourt system has been confirmed as an effective and dependable tool for evaluating multi-directional change-of-direction (COD) maneuvers. It has also been employed in the rehabilitation process following Anterior Cruciate Ligament (ACL) injuries and for multi-directional training purposes. This study investigated by means of the SpeedCourt system determines 1) whether there is any difference in COD parameters and countermovement jumps (CMJ) between United Arab Emirates (UAE) and non-UAE professional footballers 2) whether there is any difference between the two lower limbs during change-of-direction manoeuvres.
Methodology: This analysis included 100 professional football players from UAE or Non-UAE football clubs who were tested at FIFA Medical Centre of Excellence. With the help of Speedcourt system, 6-s tapping, countermovement jump (CMJ) and chase 15-s tests were performed. Comparison was done between UAE and non-UAE footballers and also between the dominant and non-dominant sides.
Results: Out of the 100 players, 83 players were right foot dominant. Apart from the countermovement jump test, there was no significant difference in results between UAE and non-UAE football players. Average time to turn for dominant and non-dominant sides did not show any significant difference, for either group.
Conclusion: There is no difference in 6-s tapping, Chase 15-s tests or limb asymmetry amongst UAE and Non-UAE footballers. However, the non-UAE footballers showed significantly better performance in Countermovement Jump Test. The data provide baseline values for forthcoming sports medicine research, which can be taken into account when creating injury prevention or return-to-sport protocols, particularly with regard to change of direction parameters and countermovement jump.

Purpose: Wingfoiling is a new popular water sport. Data on the risk of injury or overuse injuries are not yet available. The aim of the study was to analyze the incidence, mechanisms and risk factors for wingfoiling related injuries and the acceptance of safety equipment.
Patients and methods: Data for this retrospective study were collected through an online standardized questionnaire. It was accessible from January 2022 to June 2022. Information on demographics, injury history, overuse complaints, use of (safety)equipment and fitness routines over the past 12 months were asked.
Results: A total of 415 completed the questionnaire in full and could be included in the study. Fourteen percent (n = 59) were female, 86% (n = 356) were male. The average age was 43.5 years. Fourteen percent (n = 59) participated in competitions. Thirty-one percent (n = 129) of all participants suffered at least one injury in the past 12 months out of a total of 356 injuries. This corresponds to an injury incidence of 5.7/1000h. Typical mechanism of injury was contact with the own sports equipment. The most frequent cause was individual riding errors due to fatigue with 77.5% (n = 276). The most common acute injury types were contusions, strains, cuts and abrasions of the lower extremities. In the case of chronic complaints (n = 173), the shoulder and knee joint were mainly affected. Seventy-three percent (n = 304) of the participants regularly used a protective equipment, such as a helmet or impactvest.
Conclusion: The injury rate of wingfoiling is comparable to windsurfing and kitesurfing. The majority of injuries are minor injuries to the lower extremities. In case of serious injuries, it is mainly the bony thorax that is affected. Most participants already use protective equipment. Overuse complaints mostly affect the large joints.
