Most elite athletes return to preinjury competitive activity after surgical treatment for medial malleolus stress fractures.

PURPOSE: To provide return-to-performance outcomes after surgical treatment for medial malleolus stress fractures in the elite athlete. Additionally, to describe an individualised surgical approach in the management of medial malleolus stress fractures. METHODS: Five athletes (six ankles) underwent surgical treatment for a medial malleolus stress fracture. The surgical technique was based on the extent of the fracture line in steps with first arthroscopic debridement of bony spurs, microfracturing of the fracture line and screw fixation. Return-to-performance data included time to return to sport-specific training, normal training, first competitive activity, performance and the return-to-performance rate. RESULTS: Patients returned to sport-specific training at a median of 10 weeks. They started normal training at 16 weeks postoperatively and returned to their first competitive activity after 19 weeks. All patients had bony spurs on the distal tibia which were arthroscopically debrided. One patient received arthroscopic debridement of bony spurs alone. Four patients received additional microfracturing of the fracture line and three patients received screw fixation. All patients achieved clinical and radiographic union on follow-up computed tomography scan at 3 months postsurgery. At latest follow-up, no refractures nor hardware complications, nor any other complications were observed. CONCLUSION: Arthroscopic debridement of bony spurs, debridement and microfracturing of the fracture line and screw fixation are all viable surgical tools in the management of medial malleolus stress fractures in elite athletes. The surgical approach containing these options should be tailored to the individual athlete based on the fracture line in the sagittal plane. While most athletes return to full competitive activity in 3-4 months, time to self-reported return to full performance is often much longer. LEVEL OF EVIDENCE: Level IV.

Unmasking mental health symptoms in female professional football players: a 12-month follow-up study.

Objective: To calculate the prevalence rates of mental health symptoms among female professional football players over a 12-month period and to explore the associations of severe injury and related surgery with mental health symptoms among female professional footballers. Methods: An observational prospective cohort study was conducted over a 12-month follow-up period by distributing an electronic questionnaire three times. The questionnaire was based on validated screening tools for assessing mental health symptoms. Results: A total of 74 female professional football players participated in this study. Mental health symptoms ranged from 1% for substance misuse to 65% for sport-psychological distress at baseline, from 6% for anxiety to 53% for sport-psychological distress 6 months postbaseline and from 3% for substance misuse to 55% for sport-psychological distress 12 months postbaseline. The prevalence of disordered eating remained between 15% and 20% over the 12-month period. Only one of the associations was statistically significant. Female professional football players were nearly twice as likely to report sport-related psychological distress following every surgery. Conclusions: The substantial prevalence of mental health symptoms among female professional football players emphasises the need for increased attention, awareness and interventions. Additionally, female professional football players are nearly twice as likely to report sport-related psychological distress after each surgery. Sports medicine physicians and mental health professionals working in female football should provide standard care, which involves identifying, monitoring and implementing tailored interventions for mental health symptoms.

Determination of the Prevalence of Knee and Hip Clinical Osteoarthritis in the Active Professional Male Footballer and Its Association with Pain, Function, Injury and Surgery.

OBJECTIVE: To comment on and explore (1) the prevalence of clinical knee and hip osteoarthritis (OA); (2) the association between pain or function and clinical knee or hip OA; (3) the association between injury or surgery and clinical knee or hip OA. METHODS: Participants were recruited from FIFPRO members. A total of 101 footballers consented to answer (1) a developed questionnaire, (2) patient-reported outcome measures, and (3) be evaluated by their team physician for clinical knee or hip OA. RESULTS: Of the 53% evaluated for clinical knee and hip OA, a prevalence of 9.43% and 7.55% of knee and hip OA, respectively, was found. There was a significant and strong association between knee (p = 0.033; Cramers v Value = 0.523) and hip pain (p = 0.005; Cramers v Value = 0.602) and clinical OA. A significant association existed between Hip dysfunction and Osteoarthritis Outcome short form Scores and clinical OA of the hip (p = 0.036). The odds of clinical knee OA were 1.5 and 4.5 times more after one or more injuries or surgeries, respectively. There was no association between playing position and clinical OA. CONCLUSION: There is a low prevalence of a clinical knee or hip OA in the active professional male footballer. Pain may be a valid symptom to predict or monitor knee or hip OA. Validated assessment tools should be utilised to identify a negative effect on function. The odds of developing clinical OA in the knee with the number of injuries or surgeries. The hip presents with earlier clinical signs of OA compared to the knee.

Ankle osteoarthritis and its association with severe ankle injuries, ankle surgeries and health-related quality of life in recently retired professional male football and rugby players: a cross-sectional observational study.

OBJECTIVES: To determine (1) the prevalence of ankle osteoarthritis (OA) among former professional football and rugby players, (2) assess the association between ankle injuries or ankle surgeries with ankle OA, and (3) compare the mental and physical quality of life (QoL) between former professional football and rugby players with and without OA. METHODS: We conducted a questionnaire-based observational study with a cross-sectional design. Former professional football and rugby players were recruited by the Football Players Worldwide and the International Rugby Players. Information concerning ankle OA, sustained ankle injuries and ankle surgeries was gathered (medical record or most recent medical professional). Health-related QoL was assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS) physical and mental health scores. RESULTS: Overall, 553 former professional football (n=401) and rugby (n=152) players were enrolled in the study (response rate of 56%). Ankle OA prevalence among former professional football and rugby players was 9.2% and 4.6%, respectively. Football players were more likely to suffer from ankle OA following every ankle injury and/or surgery. Football and rugby players with ankle OA had similar PROMIS physical and mental health scores to the norm for the general population. CONCLUSION: Former professional football and rugby players had higher ankle OA prevalence than the general population (3.4%). Football players are more likely to suffer from ankle OA following every ankle injury and/or surgery. No clinically relevant difference was seen for physical or mental health-related QoL among football and rugby players. Preventive measures for ankle injuries are recommended.

Monitoring the health of transitioning professional footballers: protocol of an observational prospective cohort study.

INTRODUCTION: Transitioning out of professional football is a challenging time in most players' lives. During these preretirement and postretirement years, professional footballers may struggle with their mental, musculoskeletal, neurocognitive and cardiovascular health. Currently, longitudinal data about these health conditions are lacking. This article presents the design of a prospective cohort study with the primary aim of gathering epidemiological evidence about the onset and course of mental, musculoskeletal, neurocognitive and cardiovascular health conditions in professional footballers during their preretirement and postretirement years and evaluating the associations between risk indicators and the health conditions under study in these players. METHODS AND ANALYSIS: An observational prospective cohort study with repeated measurements over a follow-up period of 10 years will be conducted among at least 200 professional footballers (male; 27 (±1) years old). Mental health will be explored by assessing symptoms of distress, anxiety, depression, sleep disturbance, alcohol misuse, drug misuse and disordered eating. Musculoskeletal health will be explored by assessing severe joint injury and related surgery, clinical and radiological osteoarthritis, and joint function (hips, knees and ankles). Neurocognitive health will be explored by assessing the concussion, brain structure and functioning, and neurocognitive functioning. Cardiovascular health will be explored by assessing blood pressure, lipid profile and ECG abnormalities. ETHICS AND DISSEMINATION: Ethical approval for the study was provided by the Medical Ethics Review Committee of the Amsterdam University Medical Centers. The results of the study will be submitted to peer-reviewed journals, will be presented at scientific conferences and will be released in the media (postpublication). TRIAL REGISTRATION NUMBER: The Dutch Trial Registry (Drake Football Study NL7999).

Knee osteoarthritis in professional football is related to severe knee injury and knee surgery.

BACKGROUND: As a consequence of severe knee injuries, knee osteoarthritis (OA) seems prevalent in retired professional footballers. However, some epidemiological data remain missing, for instance whether knee OA is also prevalent in current professional footballers, whether knee OA is associated with knee injuries and surgeries, and whether knee OA leads to a lower level of functioning. Therefore, three research questions were answered: (i) what is the prevalence of knee osteoarthritis (OA) among current and retired professional footballers? (ii) is severe knee injury or knee surgery associated with knee OA among current and retired professional footballers? (iii) what are the consequences of knee OA on physical knee function among current and retired professional footballers? METHODS: An observational study based on a cross-sectional design by means of questionnaires was conducted. Participants were current and retired professional footballers recruited by the World Players' Union (FIFPro). Information about severe knee injury and knee OA was gathered (medical record or team doctor), while physical knee function was assessed through a validated scale. RESULTS: A total of 1360 participants (964 current and 396 retired professional footballers) were enrolled in the study (response rate of 54%). Prevalence of knee OA was 13% among current players and 28% among retired players (p < 0.01), being higher among older players. Current and retired professional footballers were nearly twice as likely to suffer from knee OA by every additional severe knee injury and by every additional knee surgery (risk ratio: 1.72-1.96; p < 0.01). Current and retired professional footballers with knee OA reported a lower level of physical knee function than current and retired players without OA (p < 0.01), their physical knee function being also lower than reference values (adult population, young athletic population and amateur footballers). CONCLUSION: The prevalence of knee OA was higher among retired than among current professional footballers and reached up to 40%, leading to negative consequences for their physical knee function. Current and retired professional footballers were nearly twice as likely to suffer from knee OA by every additional severe knee injury and by every additional knee surgery incurred during their career. Management of knee OA should be prioritized among professional footballers, especially to prevent the worsening of the condition during their retirement years.

A Tailored Web-based Advice Tool for Skiers and Snowboarders: Protocol for a Randomized Controlled Trial.

BACKGROUND: Being active in sports has many positive health effects. The direct effects of engaging in regular physical activity are particularly apparent in the prevention of several chronic diseases, including cardiovascular disease, diabetes, cancer, hypertension, obesity, depression, and osteoporosis. Besides the beneficial health effects of being active, sports participation is unfortunately also associated with a risk of injuries. In the case of many sports injuries (eg, winter sports) preventive measures are not compulsory, which means that a behavioral change in sports participants is necessary to increase the use of effective measures, and subsequently prevent or reduce injuries in sports. OBJECTIVE: The evidence-based Wintersportklaar online intervention has been developed to stimulate injury preventive behavior among skiers and snowboarders. In this article, the design of the effectiveness study will be described. METHODS: A randomized controlled trial with a follow-up period of four months during the winter sport season will be conducted. The participants consist of inexperienced skiers and snowboarders. At baseline, skiers and snowboarders in the intervention and control groups are asked to report the injury preventive measures they usually take during their preparation for their winter sport holiday. One and three months after baseline, skiers and snowboarders are asked to report retrospectively in detail what measures they took regarding injury prevention during their current winter sport preparation and winter sport holiday. Descriptive analyses (mean, standard deviation, frequency, range) are conducted for the different baseline variables in both study groups. To evaluate the success of the randomization, baseline values are analyzed for differences between the intervention and control groups (chi square, independent T tests and/or Mann-Whitney test). Chi square tests and/or logistic regression analyses are used to analyze behavioral change according to the intention to treat principle (as initially assigned). RESULTS: The project was funded in 2016 and enrolment was completed in 2017. Data analysis is currently under way and the first results are expected to be submitted for publication in 2018. CONCLUSIONS: To combat the negative side effects of sports participation, the use of injury preventive measures is desirable. As the use of injury prevention is usually not compulsory in skiing and snowboarding, a behavioral change is necessary to increase the use of effective injury preventive measures in winter sports.

The mental wellbeing of current and retired professional cricketers: an observational prospective cohort study.

OBJECTIVE: Scientific knowledge about symptoms of common mental disorders in professional cricket is non-existent. Consequently, the aims of the study were to determine the prevalence and the 6 months incidence of symptoms of common mental disorders (CMD: distress, anxiety/depression, sleep disturbance, adverse alcohol use) among current and former professional cricketers and to explore the association of potential stressors (significant injury, surgery, adverse life events, career dissatisfaction) and CMD. METHODS: An observational prospective cohort study with a follow-up period of 6 months was conducted among current and former professional cricketers from South Africa. Using validated questionnaires to assess symptoms of common mental disorders as well as several stressors, an electronic questionnaire was set up and distributed by the South African Cricketers Association (SACA). RESULTS: A total of 116 participants enrolled at baseline (overall response rate of 33%) and 76 of those participants completed the 6 month follow-up (follow up rate of 66%). The prevalence of symptoms of CMD in current professional cricketers was 38% for distress, 38% for sleep disturbance, 37% for anxiety/depression and 26% for adverse alcohol use. Among former professional cricketers, baseline prevalence as was 26% for distress, 24% for anxiety/depression, 21% for sleep disturbance and 22% for adverse alcohol use. Career dissatisfaction led to an increased risk of distress, anxiety/depression and sleep disturbance in current professional cricketers. Surgeries and adverse life events led to an increase in reported symptoms of distress and anxiety/depression in current professional cricketers. CONCLUSIONS: It was concluded that symptoms of CMD are prevalent in both current and former professional cricketers and the association with surgery, adverse life events and cricket career dissatisfaction may provide some insight into possible mechanisms.

The prevalence and risk indicators of symptoms of common mental disorders among current and former Dutch elite athletes.

The aim of the study was to determine the prevalence and comorbidity of symptoms of common mental disorders (distress, anxiety/depression, sleep disturbance, eating disorders, adverse alcohol use) among current and former Dutch elite athletes, and to explore the inference between potential risk indicators (severe injury, surgery, life events, sport career dissatisfaction, social support) and the outcomes measures under investigation. Cross-sectional analyses were conducted on baseline questionnaires from an ongoing prospective cohort study among 203 current and 282 former elite Dutch athletes (response rate: 28% among current athletes and 95% among former athletes). Based on validated scales, an electronic questionnaire was set up and distributed. Prevalence (4-week) ranged from 6% for adverse alcohol use to 45% for anxiety/depression among current elite athletes, and from 18% for distress to 29% for anxiety/depression among former elite athletes. A higher number of past severe injuries, higher number of past surgeries, higher number of recent life events, higher level of career dissatisfaction and lower level of social support were related to the occurrence of symptoms of common mental disorders among both current and former elite athletes. On average, the 4-week prevalence of common mental disorders as shown in our study among current and former Dutch elite athletes were similar to the ones found among athletes from other sports disciplines and does compare with the lifetime prevalence estimates in the general population of the Netherlands.

Osteoarthritis is associated with symptoms of common mental disorders among former elite athletes.

PURPOSE: The primary aim was to establish the association between osteoarthritis (OA) and the occurrence and comorbidity of symptoms of common mental disorders (CMD: distress, anxiety/depression, sleep disturbance, adverse alcohol use) in a group of former elite athletes (rugby, football, ice hockey, Gaelic sports and cricket). A secondary aim was to explore this association in the subgroups of sports. METHODS: Cross-sectional analysis was performed on the baseline questionnaires from five prospective cohort studies conducted between April 2014 and January 2016 in former elite athletes of rugby, football, ice hockey, Gaelic sports and cricket. The presence of OA (diagnosed by a medical professional) was examined with a single question, and symptoms of CMD were evaluated through multiple validated questionnaires (4DSQ, GHQ-12, PROMIS, AUDIT-C). RESULTS: There was a significant association between OA and symptoms of distress (OR 1.7, 95 % CI 1.2-2.6), sleep disturbance (OR 1.6, 95 % CI 1.1-2.3), adverse alcohol use (OR 1.8, 95 % CI 1.2-2.6) and a comorbidity of symptoms of CMD (OR 1.5, 95 % CI 1.0-2.1) in former elite athletes. CONCLUSION: OA might be a risk factor for developing symptoms of CMD in former elite athletes. The clinical relevance of this study is that an interdisciplinary approach to the clinical care and support of former elite athletes after their careers is advocated as the interaction between the physical and mental health issues occurring on the long term is complex. Monitoring OA among former elite athletes should be empowered while strategies to prevent symptoms worsening should be developed and implemented. The self-awareness, prevention and care of mental health problems that might occur after a professional sports career should also be addressed. LEVEL OF EVIDENCE: Level III.

Are Level of Education and Employment Related to Symptoms of Common Mental Disorders in Current and Retired Professional Footballers?

BACKGROUND: Mental disorders have become a topic of increasing interest in research due to their serious consequences for quality of life and functioning. OBJECTIVES: The objective of this study was to explore the relationship of level of education, employment status and working hours with symptoms of common mental disorders (distress, anxiety/depression, sleep disturbance, adverse alcohol behaviour, smoking, adverse nutritional behaviour) among current and retired professional footballers. MATERIALS AND METHODS: Cross-sectional analyses were conducted on baseline questionnaires from an ongoing prospective cohort study among current and retired professional footballers. Based on validated scales, an electronic questionnaire was set up and distributed by players' unions in 11 countries across three continents. RESULTS: A total of 607 current professional footballers (mean age of 27 years) and 219 retired professional footballers (mean age of 35 years) were involved in the study. Among retired professional footballers, statistically significant negative correlations were found between employment status and symptoms of distress and anxiety/depression (P < 0.05), as well as between number of working hours and symptoms of anxiety/depression (P < 0.05). No other statistically significant associations were found among retired players. Among current professional footballers, level of education was not associated with symptoms of common mental disorders. CONCLUSIONS: Among retired professional footballers, employment status as well as a higher number of working hours was weakly correlated to symptoms of distress and anxiety/depression. Combining a football career with sustainable attention for educational and career planning might be important and of high priority.

Prevalence and determinants of symptoms related to mental disorders in retired male professional footballers.

BACKGROUND: The objective of this study was to determine the prevalence of symptoms related to mental disorders (distress, anxiety/depression, sleep disturbance, adverse alcohol behavior, adverse smoking behavior, adverse nutrition behavior) among retired professional footballers, and to explore their associations with stressors, i.e. determinants such as severe injury, surgery, life events and career dissatisfaction. METHODS: Cross-sectional analyses were conducted on baseline questionnaires from an ongoing prospective cohort study among retired male professional footballers. Based on validated questionnaires to assess both stressors and symptoms related to mental disorders, an electronic questionnaire was set up and distributed by players' unions in 11 countries across three continents. RESULTS: Prevalence of symptoms related to mental disorders among 219 retired professional footballers ranged from 11% for adverse smoking behavior and 18% for distress, to 35% for anxiety/depression and 65% for adverse nutrition behavior. Especially life events that occurred in the previous six months was positively associated with distress (OR=1.3; 95% CI: 1.0-1.6), anxiety/depression (OR=1.6; 95% CI: 1.2-2.1), sleeping disturbance (OR=1.3; 95% CI: 1.1-1.7) and adverse nutrition behavior (OR=1.4; 95% CI: 1.0-1.8). CONCLUSIONS: A high prevalence of symptoms related to mental disorders was found among retired professional footballers, confirming a previous study in a similar study population. Relationships were established between symptoms of mental disorders and severe injuries, recently occurred life events, and career dissatisfaction.

Epidemiology of symptoms of common mental disorders among elite Gaelic athletes: a prospective cohort study.

OBJECTIVE: Scientific knowledge about symptoms of common mental disorders among elite Gaelic athletes is lacking. Consequently, this study aimed to (i) determine the prevalence, comorbidity and 6-month incidence of symptoms of common mental disorders (distress, anxiety/depression, sleep disturbance, adverse alcohol use) among elite Gaelic athletes and (ii) evaluate their association with potential stressors (severe musculoskeletal injuries, surgeries, recent life events, career dissatisfaction). METHODS: An observational prospective cohort study by means of questionnaires was conducted over six months among elite Gaelic athletes (N=204). Using validated questionnaires to assess symptoms of common mental disorders as well as several stressors, an electronic questionnaire was set up and distributed by the Gaelic Players' Association. RESULTS: Prevalence ranged from 23% for adverse alcohol use to 48% for anxiety/depression. Around 24% of the participants reported at baseline two symptoms. Six-month incidence ranged from 11% for sleep disturbance to 21% for anxiety/depression. Severe musculoskeletal injury, surgery, recent life events and career dissatisfaction led to an increased risk for common mental disorders. CONCLUSION: Our findings indicate that raising the self-awareness of all stakeholders in Gaelic sports about common mental disorders should be prioritized, as well as the evidence-based development and application of adequate preventive and supportive measures.

Prevalence and determinants of symptoms of common mental disorders in retired professional Rugby Union players.

The primary aim of this study was to determine the prevalence of symptoms of common mental disorders (CMD) (distress, anxiety/depression, sleeping disturbance, adverse nutrition behaviour, adverse alcohol behaviour and smoking) among retired professional Rugby Union players. The secondary aim was to explore the associations between stressors (life events, Rugby Union career dissatisfaction) and the health conditions under study. Therefore, cross-sectional analyses were conducted on baseline questionnaires from an ongoing prospective cohort study of retired professional Rugby Union players. An electronic questionnaire was established using validated questionnaires to assess symptoms of CMD and stressors. The electronic questionnaire was subsequently distributed to retired players by the national Rugby Union players' associations in France, Ireland and South Africa. Among 295 retired professional Rugby Union players (mean age of 38 years), prevalence rates were 25% for distress, 28% for anxiety/depression, 29% for sleeping disturbance, 62% for adverse nutrition behaviour, 15% for smoking and 24% for adverse alcohol behaviour. A higher number of life events were associated with distress (OR = 1.2; 95% CI 1.1-1.4), anxiety/depression (OR = 1.6; 95% CI 1.2-2.1), sleeping disturbance (OR = 1.6; 95% CI 1.2-2.1) and adverse nutrition behaviour (OR = 1.8; 95% CI 1.3-2.5). A higher level of dissatisfaction of the player's Rugby Union career was associated with distress (OR = 0.9; 95% CI 0.8-1.0), sleeping disturbance (OR = 0.9; 95% CI 0.9-1.0), smoking (OR = 0.9; 95% CI 0.9-1.0) and adverse nutrition behaviour (OR = 0.9; 95% CI 0.8-0.9). In conclusion, our study suggests that prevalence of symptoms of CMD is high among retired professional Rugby Union players, being associated with both a higher number of life events and a higher level of Rugby Union career dissatisfaction.

Are severe musculoskeletal injuries associated with symptoms of common mental disorders among male European professional footballers?

PURPOSE: To explore the associations of severe musculoskeletal injuries (joint and muscles) and surgeries with symptoms of common mental disorders (distress, anxiety/depression, sleeping disturbance, adverse alcohol behaviour , smoking, adverse nutrition behaviour) among male European professional footballers. METHODS: Cross-sectional analyses were conducted on electronic questionnaires completed by professional footballers recruited from the national players' unions of Finland, France, Norway, Spain or Sweden. The number of severe (time loss of more than 28 days) musculoskeletal injuries (total, joint, muscle) and surgeries during a professional football career was examined through four questions, while symptoms of common mental disorders were evaluated through validated scales. RESULTS: A total of 540 professional footballers (mean age of 27 years; 54 % playing in the highest leagues) participated in the study. Sixty-eight per cent of the participants had already incurred one or more severe joint injuries and 60 % one or more severe muscle injuries. Prevalence of symptoms of common mental disorders ranged from 3 % for smoking to 37 % for anxiety/depression and 58 % for adverse nutrition behaviour. The number of severe musculoskeletal injuries during a football career was positively correlated with distress, anxiety and sleeping disturbance, while the number of surgeries was correlated with adverse alcohol behaviour and smoking. Professional footballers who had sustained one or more severe musculoskeletal injuries during their career were two to nearly four times more likely to report symptoms of common mental disorders than professional footballers who had not suffered from severe musculoskeletal injuries. CONCLUSION: It can be concluded that the number of severe musculoskeletal injuries and surgeries during a career is positively correlated and associated with symptoms of common mental disorders among male European professional footballers. This study emphasises the importance of applying a multidisciplinary approach to the clinical care and support of professional footballers, especially when a player faces lengthy periods without training and competition as a consequence of recurrent severe joint or muscle injuries. LEVEL OF EVIDENCE: III.

Symptoms of Common Mental Disorders and Adverse Health Behaviours in Male Professional Soccer Players.

To present time, scientific knowledge about symptoms of common mental disorders and adverse health behaviours among professional soccer players is lacking. Consequently, the aim of the study was to determine the prevalence of symptoms of common mental disorders (distress, anxiety/depression, sleep disturbance) and adverse health behaviours (adverse alcohol behaviour, smoking, adverse nutrition behaviour) among professional soccer players, and to explore their associations with potential stressors (severe injury, surgery, life events and career dissatisfaction). Cross-sectional analyses were conducted on baseline questionnaires from an ongoing prospective cohort study among male professional players. Using validated questionnaires to assess symptoms of common mental disorders and adverse health behaviours as well as stressors, an electronic questionnaire was set up and distributed by players' unions in 11 countries from three continents. Prevalence of symptoms of common mental disorders and adverse health behaviours among professional soccer players ranged from 4% for smoking and 9% for adverse alcohol behaviour to 38% for anxiety/depression and 58% for adverse nutrition behaviour. Significant associations were found for a higher number of severe injuries with distress, anxiety/depression, sleeping disturbance and adverse alcohol behaviour, an increased number of life events with distress, sleeping disturbance, adverse alcohol behaviour and smoking, as well as an elevated level of career dissatisfaction with distress, anxiety/depression and adverse nutrition behaviour. Statistically significant correlations (p<0.01) were found for severe injuries and career dissatisfaction with most symptoms of common mental disorders. High prevalence of symptoms of common mental disorders and adverse health behaviours was found among professional players, confirming a previous pilot-study in a similar study population.

Outcome After Surgical Repair of Proximal Hamstring Avulsions: A Systematic Review.

BACKGROUND: At the present time, no systematic review, including a quality assessment, has been published about the outcome after proximal hamstring avulsion repair. PURPOSE: To determine the outcome after surgical repair of proximal hamstring avulsions, to compare the outcome after acute (≤4 weeks) and delayed repairs (>4 weeks), and to compare the outcome after different surgical techniques. STUDY DESIGN: Systematic review and best-evidence synthesis. METHODS: PubMed, CINAHL, SPORTdiscus, Cochrane library, EMBASE, and Web of Science were searched (up to December 2013) for eligible studies. Two authors screened the search results separately, while quality assessment was performed by 2 authors independently using the Physiotherapy Evidence Database (PEDro) scale. A best-evidence synthesis was subsequently used. RESULTS: Thirteen studies (387 participants) were included in this review. There were no studies with control groups of nonoperatively treated proximal hamstring avulsions. All studies had a low methodological quality. After surgical repair of proximal hamstring avulsion, 76% to 100% returned to sports, 55% to 100% returned to preinjury activity level, and 88% to 100% were satisfied with surgery. Mean hamstring strength varied between reporting studies (78%-101%), and hamstring endurance and flexibility were fully restored compared with the unaffected side. Symptoms of residual pain were reported by 8% to 61%, and reported risk of major complications was low (3% rerupture rate). No to minimal difference in outcome was found between acute and delayed repair in terms of return to sports, patient satisfaction, hamstring strength, and pain. Achilles allograft reconstruction and primary repair with suture anchors led to comparable results. CONCLUSION: The quality of studies included is low. Surgical repair of proximal hamstring avulsions appears to result in a subjective highly satisfying outcome. However, decreased strength, residual pain, and decreased activity level were reported by a relevant number of patients. Minimal to no differences in outcome of acute and delayed repairs were found. Limited evidence suggests that an Achilles allograft reconstruction yields results comparable with primary repair in delayed cases where primary repair is not possible. High-level studies are required to confirm these findings.
