To describe the treatment and morbidity of lower limb (LL) football fractures in regard to returning to football in a known UK population at all skill levels. All football fractures during 2007–2008 sustained by the Lothian population were prospectively collected with the diagnosis being confirmed by the senior author when patients attended the only adult orthopaedic service in Lothian. Patients living outside the region were excluded from the study. Patients were contacted in August 2010 to ascertain their progress in return to football. There were 424 fractures in 414 patients. 366 fractures (86%) in 357 patients (86%) were followed up with a mean interval of 30 months (range 24–36 months). Of these 32% were sustained in the LL. 88% of LL injuries returned to football compared to 85% of upper limb (UL) fractures (p=0.4). 60% of LL patients were treated as outpatients. 35% were operated on −26% had ORIF and 9% IM Nailing. The most common LL fractures were Ankle 38%, Tibial Diaphysis 14%, 5th Metatarsal 11%, Fibula 9% and Great Toe 7%. Only one of the fractures was an open injury - Gustillo Class 1 2nd Phallanx Foot. Three of the 12 patients who underwent IM nailing required fasciotomy. One patient in the operative cohort developed a significant infection. The mean time for return to football for conservative treatment was 17 weeks (range 3–104 weeks), and for operative treatment 41 weeks (range 10–104 weeks). 91% of patients treated conservatively returned to football, compared to 84% of the operative cohort (p=0.3). 43% of patients had ongoing symptoms from their injury. 9% of the operative cohort required removal of metal work or further operative intervention. 83% of patients returned to the same level of football or higher following injury. Patients under 30 were 1.4 times more likely to return to sport than those over 30 (p<0.05). We have previously demonstrated that football is the most common cause of sporting fracture(1), yet little is known about patient outcome following fractures. LL fractures are less common than UL fractures, and there is no difference in the proportion of patients returning to football following LL fractures and UL fractures. Over half of LL fractures are treated as outpatients and the incidence of open fractures is very low. There is no significant difference between the operative and conservative groups in their return to football. In the over 30 age group, sustaining a fracture may act as a catalyst to quit football. This may explain the higher non-return rate compared to the under 30 age group. 43% of patients perceive that they have ongoing problems with their fracture over 24 months post-injury reflecting the considerable morbidity of football-related fractures

To illustrate the incidence and epidemiology of fractures due to football. All inpatient and outpatient fractures from a prospectively collected database for a defined population in 2000 were retrospectively analysed. There were 396 football fractures, 96% male. Football caused 39% of the 1022 sports fractures in 2000. This represented 5% of the 8151 fractures in total. The incidence was 61/105. 115/105 in males and 5 /105 in females. The average age was 22.9 years; 22.8 in males and 26.6 in females. 77% of fractures were treated as outpatients. The top five fractures representing 84% of the injuries were Radius+Ulna 30%, Phalanx 19%, Tibial+Fibula 18%, Metacarpal 11% and Clavicle 5%. 71% were upper-limb fractures. The busiest two months were October and May 17% and 14% respectively. The quietest two months were February and December at 5%. Although the epidemiology of football injuries will vary amongst different populations, these results can be generalized to similar population bases. Results will be valuable to medical professionals supporting football teams, enabling them to focus their attention on treating the most common injuries, the majority being treated as outpatients. Football is the most common cause of fractures in sport. As participation increases, the incidence of fractures is likely to reflect this. Upper limb fractures account for over 2/3 rd of fractures with radius+ulna fractures accounting for up to a 1/3rd of fractures; the majority can be treated as an outpatient. Therefore medical teams should be familiar with standard treatment regimes, possible impact on players’ futures and time out of sport

Football player's performance during competitive matches greatly depends on fitness and training. The use of GPS (Global Positioning System) has been revolutionary in the monitoring of player intensity during training. The aim of the study was to investigate the difference in training intensity between defenders, midfielders and forwards and if injury sustained was directly related to the intensity of training. GPS (Catapult Minimax GPS 10Hz) was used to collect training data for a professional British football club playing in the Championship, for the year August 2011/April 2012. Each player wore a GPS unit during each training session and the raw data was logged. The GPS calculates the player load which is a measure of intensity of training. It is a summation of instantaneous change of forward, sideway and upward accelerations. Adjustments are made for match days and injuries according to a defined set of rules. A total player load was obtained for each month and at the end of the season. The different injuries sustained throughout the year were logged for each player. This study shows that there is a difference between the intensity of training in different groups of players. The midfielders trained at the highest intensity and, in this group of professional football players, defenders sustained the most injuries GPS technology allows monitoring of player intensity during training. The data obtained will guide training and fitness coaches model training for the individual group of players. This will prepare players for official matches and eventually may help predict and prevent injuries

Objective: To ascertain the epidemiology of ankle injuries in elite youth football. Design: Retrospective analysis of prospectively collected injury data from English Football Association Academies. Setting: Forty-one FA Football Academies, between 1998 and 2006. Participants: For the complete seasons studied, a total of 14776 players were registered from U9 to the U16 age category – a mean of 2463 players per year. All ankle injuries of sufficient severity to miss 48 hours or more training were studied – 2563 injuries in total. Main outcome measurements: The incidence and burden of ankle injuries in this population, and factors associated with injury. Results: There was a mean incidence of one ankle injury per player per year, and a mean of 20 training days and 2 matches were missed per ankle injury. Increased injury rates were seen in older players, in competition and later in each half of match time. Peaks in injury were observed early in the season and after the winter break. In competition, more injuries were associated with a contact situation than in training. Eighty-eight injuries (3.4%) required a lay-off of three months or more and in 18 (0.7%) cases, the player failed to return to training. In total, 52290 training days and 5182 match appearances were lost through ankle injury. The majority of injuries were sprains, but more severe injuries occurred accounted for 3.9% of the total. Conclusions: Ankle injuries are common in young football players, and are often severe, with prolonged loss of training time. This has potential far reaching implications, both on and off the field. Further syudy in this area is suggested

Introduction: Regular review [. 1. , . 2. ] of cervical injuries occurring in rugby players is an important step toward maximising the safety of the players. It is hoped that the recognition of recurring patterns of injury would lead to appropriate rule modification by the regulatory bodies of the sport. Serious cervical injuries in rugby have been reported to occur by a range of mechanisms, including those involved with scrummaging, tackling, rucking and mauling. Spinal flexion is the commonest mechanism of injury and has been associated with scrum engagement, scrum collapse, rucking or mauling, and mistimed tackling. The second most common mechanism of cervical spinal injury is hyper-extension. This commonly occurs during tackling, particularly the ‘gang tackle’ involving several participants simultaneously, where sudden deceleration of a player’s head may lead to cervical hyperextension, focal spinal stenosis and potential damage to the spinal cord by a “pincer” mechanism. The most commonly reported levels of injury are C5/6 and C4/5 [. 3. ]. Methods: A retrospective review of neck injuries presenting to a major spinal injuries facility and resulting from all codes of football (rugby union, rugby league, soccer, indoor soccer and touch) was conducted and 38 cases identified. Results: Of the 38 patients 14 were injured playing rugby union, 15 rugby league, 3 soccer, 1 indoor soccer, 1 touch football and 4 were playing an unidentified code. 6 players were injured while scrummaging, 5 rugby union and 1 rugby league. 21 people were injured as tacklees, 4 as tacklers and 2 with unspecified involvement in a tackle. 1 person was injured whilst “heading” the ball, and 3 people were injured in a non-contact or unspecified action. At final follow-up, 4 people were found to be quadriplegic (ASIA A), 10 quadriparetic (ASIA B – 0 C −1 and D –9) and 24 recovered completely (ASIA E)

Introduction. This biomechanics investigation evaluated commercially available studded and bladed football boots to determine whether boot type influences potential non-contact ACL injury when football players sidestep cut. Methods. Fifteen professional outfield male football players, without history of lower limb injury, with at least two consecutive injury-free seasons participated. Each undertook three trials of a straight line run and sidestep cuts at 30° and 60° with approach velocity 5.5ms. -1. - 6.0ms. -1. on a FIFA (Fédération Internationale de Football Association) approved artificial football surface. Four pairs of standardised football boots (two bladed and two studded) were investigated. Using 3D inverse dynamics analyses based on an eight camera gait analysis system (120Hz) synchronised with a force platform (960Hz), peak absolute knee internal tibial rotational moments (M. z. ), valgus moments (M. y. ) and anterior joint forces (F. x. ) were determined throughout the stance phase. Values were compared with cadaveric critical limits for ACL injury. A univariate repeated measures ANOVA quantified differences between the variables as a function of cutting angle and boot type. Results. Comparisons between the investigated boots revealed M. z. , M. y. and F. x. were similar for each manoeuvre. Straight line running using studded and bladed boots was associated with M. z. , M. y. and F. x. insufficient for cadaveric injury. Sidestep cutting using studded and bladed boots resulted in M. z. and M. y. significantly greater than during straight line running (p < 0.001), M. z. and F. x. exceeding critical limits and M. y. values which did not. Conclusion. The boot type did not significantly alter potential non-contact ACL injury based on cadaveric critical limits. Sidestep cutting using studded and bladed football boots resulted in M. z. and F. x. sufficient for non-contact ACL injury. Sidestep cutting, when compared to straight line running, may influence potential non-contact ACL injury more than the boot type used by altering knee joint loading to a greater extent

Introduction. Knee injuries are common amongst footballers. The aim of this study was to establish frequency and variation of knee injuries within one English Premier League (EPL) professional football club over two seasons, to assess number of days missed due to injury, and analyse current treatment regimen for each injury type. Method. Data was collected prospectively for injuries suffered by players between 2009 and 2011, spanning two EPL seasons at one EPL club. Demographics were recorded along with various factors influencing injury, including playing surface, pitch condition, dominant side, type of injury, ability to continue playing, and mechanism of injury. Time taken for return to play, and treatment received was recorded. Results. 35 injuries occurred that were severe enough to cause players to miss at least one competitive match. The commonest injury was to the medial collateral ligament (MCL) in 34%. Patella tendon injuries were seen in 29%, other injuries included meniscus tears, ACL ruptures, and osteochondral defects. All grade II MCL Injuries received sclerosant injections. 40% of patella tendon injuries were given plasma-rich protein (PRP) injections, and 30% underwent surgery. The mean recovery time following MCL and patella tendon injuries was 44 days and 77 days respectively. 60% of injuries were sustained during training and 40% were suffered in competitive games. 26% were recurring injuries, recurrent meniscus and patella tendon injuries took twice as long to recover compared to the initial injury. Conclusion. Our findings suggest that MCL and patella tendon injuries are the most common knee injuries amongst professional footballers and that meniscus tears and ligament ruptures are relatively rare in comparison. Injuries appear to occur more frequently during training. A high proportion of injuries in the study received injection therapy in the form of PRP or sclerosant. The study suggests recurrent injuries can prolong recovery two-fold

Introduction. Foot and ankle injuries are a common occurrence amongst all footballers. The aim of this study was to establish the frequency and variation of foot and ankle injuries within one English Premier League (EPL) professional football club over the course of a season and attempt to identify any factors associated with the injuries. Method. Data was collected prospectively for all foot and ankle injuries suffered by first team players over the 2008–09 and 2009–10 EPL season at one EPL club. Each player's demographics were recorded along with various factors concerning or influencing the injury including ground conditions, foot posture index score (FPIS), type of injury, ability to continue playing, recovery time, mechanism of injury and footwear type. Results. The most common injury was 5th metatarsal fracture seen in 33%. Lateral ligament sprain was seen in 28% and syndesmosis injury in 17%. The mean recovery time following 5th metatarsal fractures was 76 days. 67% of all injuries (100% of 5th metatarsal fractures) were sustained while wearing blade footwear, 17% wearing the more traditional studded footwear. Supination was the most common FPIS, present in 43%. 56% of injuries were in the dominant (kicking) side while 50% of injuries were sustained in the tackle. There were no ankle fractures observed. Conclusion. 5th metatarsal fractures are the most common foot & ankle injury amongst professional footballers, ankle fractures are relatively rare in comparison. Injuries occur more frequently with blade footwear, with supination being the most common foot posture at the time of injury

Introduction. Fifth metatarsal fractures are a common injury suffered by professional footballers. It is frequently reported in the media that such an injury will result in a 6-week absence from play. The purpose of this study was to assess frequency of media reporting of fifth metatarsal fractures, the time that is predicted by the media before the player will return to soccer and the actual time taken for the player to return to play. Methods. Internet search engines identified 40 professional footballers that suffered 49 fifth metatarsal fractures between 2001 and 2011. Information was collected from various media and team websites, match reports, photography and video evidence to provide data regarding the mechanism of injury, playing surface conditions, frequency of fractures per season, fracture treatment, estimated amount of time to be missed due to the injury and time taken to return to play. Results. 49 fractures were identified in the 40 players. 6 players suffered a recurrence of a previous fifth metatarsal fracture. 3 players sustained 5. th. metatarsal fractures in their contralateral foot. There was a trend of increased reporting of fifth metatarsal fractures over the course of the decade. 43% of fractures were sustained without contact with another player, 24% were suffered in a tackle. 77% of fractures were sustained in dry conditions. 90% of fractures were treated surgically. Mean return to play time was 14.6 weeks (range 5 to 34 weeks). The mean estimated absence in the media was 7.8 weeks (range 2 to 16 weeks), median 6 weeks. Conclusions. Fifth metatarsal fractures are being commonly reported in professional footballers with an increasing trend. Most are treated surgically. It appears that the commonly quoted period of 6 weeks before return to play is unrealistic. It should be expected that a player would be unavailable for 3 months

Background & Purpose. The co-ordinated contraction of the kinetic chain is responsible for the dissipation of force. Weakness in the kinetic chain, such as the posterior oblique sling (POS), may increase the demand on additional muscles, such as the hamstrings, to compensate. The lumbar extensors may be particularly vulnerable in the kinetic chain, as they appear difficult to strengthen due to the dominant hip extensors. Therefore, this study aimed to investigate whether participants with a history of hamstring injuries presented with low back pain because of greater deficits in lumbar extensor strength, and impaired co-ordination of the POS. Methods. Twenty male footballers were recruited (n: Injured- 9, Controls- 11). Isolated lumbar extension strength, low back pain, and the contraction time of muscles within the POS during a hip extension test were recorded. Participants were then grouped in either the injury or control group. Conclusion. No differences were observed for lumbar extensor strength (P > 0.05) or the onset of muscular contraction (P > 0.05), though 95% confidence intervals revealed the difference in gluteus maximus onset time (−0.11 – 1.06 s) could be large and may have clinical importance. Descriptive data highlighted the prevalence of back pain was 40% greater in HSI participants. Conflicts of interest. None. Sources of funding. This research was funded by the Wellcome Trust as part of their biomedical vacation award

Introduction: The health benefits of physical exercise are well recognised. In recent years the department of health has been encouraging the UK population to exercise more. We aimed to determine if there was any change in the number and pattern of sport and exercise related injuries attending a city Emergency Department (ED) over the past two decades. Methods: We undertook a prospective comparative study of patients attending an ED over two time periods: Aug 85 – April 86 and Aug 04 – April 05. All identified patients had a standardised proforma inserted into their notes which was prospectively completed by the attending clinician at the time of consultation. Results: We observed a 35% increase in sporting injuries over the 19 year period (1000 injuries out of 37036 new patients vs 1351 out of 37526, p< 0.0001). The total number of new patients attending the ED remained unchanged during this time. Males remain the majority of patients with sports injuries (86%). We noted a change in age distribution with a relative increase in patients under 16 yrs (p< 0.0001), a decrease in 16–24 yrs (p=0.0002) and an increase in patients over 40yrs (p< 0.001). There was a significant reduction in patients presenting out of hours and a significant increase in the delay to presenting at ED with the majority of patients presenting over 4 hours after the injury. Football remains the commonest cause of sports injury accounting for half of all sports injuries, followed by rugby but there has been a relative decline in skiing, martial arts jogging and squash as a cause of injury and a significant increase in injuries due to snowboarding, skateboarding and basketball. Conclusion: There has been an increase in the number of sports injuries attending hospital, which may represent a general increase in sport and exercise participation among our population

In 2008 The Christie was chosen by Manchester United Football Club to form a unique partnership. This funded a specialist Physiotherapist and Occupational Therapist to work exclusively on the Young Oncology Unit, creating the first posts of their kind in the UK. The YOU treats patients between 16–24 years old with a diagnosis of cancer, sarcoma being one of the most common in this age group. All patients attending the YOU now receive a fully comprehensive Physiotherapy and Occupational Therapy service to address their rehabilitation needs. The NICE guidelines (2005) indicate that cancer care for young adults needs to be age specific, age appropriate and undertaken by appropriately trained staff; hence the importance of having specialist therapists on the YOU. The needs of teenagers and young adults with cancer, both physically and psychologically, are more critical than at any other time in life. During their treatment patients will experience stressful events, such as alopecia, weight loss or gain, altered physical appearance, fatigue, nausea and vomiting, absence from education, and reduced contact with peers. The Physiotherapy and Occupational Therapy roles are essential in enabling young adults to adapt to their diagnosis and learn coping strategies to deal with the stressful events they encounter through their cancer experience. During this presentation we will describe the unique role of Physiotherapy and Occupational Therapy with teenagers and young adults, using case studies to illustrate the benefits of having dedicated YOU therapists. We will also share with you the innovative ways in which the Manchester United training facilities have been used for different initiatives that have greatly benefitted and motivated our patients and their families. The partnership between two local organisations, one of the biggest football clubs in the world and a world class Cancer Centre has been a unique and positive liaison

Aims

There is limited information on outcomes of revision ACL reconstruction (rACLR) in soccer (association football) athletes, particularly on return to sport and the rate of additional knee surgery. The purpose of this study was to report return to soccer after rACLR, and to test the hypothesis that patient sex and graft choice are associated with return to play and the likelihood of future knee surgery in soccer players undergoing rACLR.

Abstract. Introduction. The study aims were to demonstrate rates, level, and time taken to RTP in elite sports after ACL reconstruction (ACL-R) and compare football and rugby. Methods. A retrospective review of a consecutive series of ACL-R between 2005 and 2019 was undertaken. Patients were included if they were elite athletes and were a minimum of 2 years post primary autograft ACL-R. The outcomes measured were return to play (RTP), (defined as participation in a professional match or in national/ international level amateur competition), time to RTP after surgery, and RTP level (Tegner score). Results. Three hundred and ninety four elite athletes with 420 ACL-Rs (235 in footballers, 125 in rugby players and 60 in other sports) were included. 95.7% of all athletes returned to competition at a mean of 10.3 months after ACL-R with 90.1% at the same / higher level. There was no difference in RTP rates between rugby and football. Rugby players RTP faster than footballers (9.6 vs 10.6 months, (p=0.027). Overall re-rupture rate within 2 years was 6.4% but not significantly different between football (8.1%) and rugby (7.2%). Footballers were more likely to rupture their ACL during jumping / landing manoeuvres and to receive a PT graft than rugby players. There were no significant differences between football and rugby regarding patient characteristics, intraoperative findings and re-operation rates. Conclusion. Over 95% of all elite athletes RTP after primary ACL-R with 90% able to play at the same level. Rugby players RTP significantly faster than footballers

Abstract. Introduction. The aim of this study was to determine which factors affect a professional footballer's return to play performance level after ACL reconstruction (ACL-R). Additionally, to report their playing performance at 2 and 5 years post ACL-R compared to their preinjury performance. Methods. A retrospective review of a consecutive series of primary ACL-R undertaken in professional footballers between 2005 and 2019 was undertaken. Performance was determined by the number of minutes played and the league level compared to their pre-injury baseline. Playing time (minutes) was classified as same (within 20%), more, or less playing time for each season compared to the one year prior to surgery. Results. Two hundred footballers (mean age 24.1 ± 4.2 years) were included. 194 (97%) returned to professional football. At 2-years after ACL-R 61% of footballers were playing in the same/ higher league, 29% were playing in a lower league and 10% were not playing. At 5-years this was 35%, 37% and 28% respectively. Forty-six percent of footballers were playing the same or more minutes as pre-injury at 2 years post-surgery, 51% were at 3 and 4 years but this reduced to 45% at 5 years. The presence of >50% thickness chondral pathology, ACL-R lacking lateral extra-articular tenodesis and age over 25 years at surgery were all significant risk factors of worse performance rates after ACL-R. Conclusion. While professional footballers achieved high initial RTP rates after ACL-R, with the majority returning to pre-operative levels of competition, significant decreases in performance rates were noted over time

Anterior cruciate ligament (ACL) injuries are among the most common and debilitating knee injuries in professional athletes with an incidence in females up to eight-times higher than their male counterparts. ACL injuries can be career-threatening and are associated with increased risk of developing knee osteoarthritis in future life. The increased risk of ACL injury in females has been attributed to various anatomical, developmental, neuromuscular, and hormonal factors. Anatomical and hormonal factors have been identified and investigated as significant contributors including osseous anatomy, ligament laxity, and hamstring muscular recruitment. Postural stability and impact absorption are associated with the stabilizing effort and stress on the ACL during sport activity, increasing the risk of noncontact pivot injury. Female patients have smaller diameter hamstring autografts than males, which may predispose to increased risk of re-rupture following ACL reconstruction and to an increased risk of chondral and meniscal injuries. The addition of an extra-articular tenodesis can reduce the risk of failure; therefore, it should routinely be considered in young elite athletes. Prevention programs target key aspects of training including plyometrics, strengthening, balance, endurance and stability, and neuromuscular training, reducing the risk of ACL injuries in female athletes by up to 90%. Sex disparities in access to training facilities may also play an important role in the risk of ACL injuries between males and females. Similarly, football boots, pitches quality, and football size and weight should be considered and tailored around females’ characteristics. Finally, high levels of personal and sport-related stress have been shown to increase the risk of ACL injury which may be related to alterations in attention and coordination, together with increased muscular tension, and compromise the return to sport after ACL injury. Further investigations are still necessary to better understand and address the risk factors involved in ACL injuries in female athletes. Cite this article: Bone Jt Open 2024;5(2):94–100

Introduction. To evaluate career length after surgical treatment of combined ACL + medial collateral ligament (MCL) and ACL +posterolateral corner (PLC) surgeries in all elite athletes. Secondly, in a subgroup of male professional footballers to determine career length and competition level after ACL+MCL or ACL+PLC reconstructions and compare this to a cohort who underwent isolated ACL reconstruction (ACL-R) alone. Methods. A consecutive cohort of elite athletes undergoing combined ACL+MCL surgery and combined ACL+PLC surgery between February 2001 and October 2019 were analysed. A subgroup of male footballers from this population was compared to a previously identified cohort of male, professional footballers having had primary ACL reconstruction without other ligament surgery. A minimum 2-years follow-up was required. Outcome measures were career length and competition level. Results. Ninety-eight elite athletes were included, 50 had ACL+PLC and 48 had ACL+MCL surgeries. The timeline for return to play (RTP)was significantly longer for ACL+PLC injuries (12.8 months) as compared to ACL+MCL injuries (11.1 months, p=.019). On average, career length after surgery of an athlete in the ACL+PLC group was 4.8 years and for the ACL+MCL group 4.2 years (n.s.). In the subgroup analysis of footballers, a significantly lower number of players with combined ACL+PLC surgery were able to RTP (88%, p=.003) compared to 100%for ACL+MCL surgery and 97% for isolated ACL reconstruction, as well as requiring almost 3 months longer RTP timeline (12.9±4.2 months= .002) when compared to isolated ACL (10.2 ± 3.9 months) and combined ACL+MCL groups (10.0+2.4 months). However, career length and competition level were not significantly different between groups. Conclusion. The addition of MCL surgery to ACL-R did not affect RTP time and rate in elite athletes, nor competition level in male professional footballers compared to ACL-R alone. Moreover, the career length after successful RTP following combined ACL+MCL or ACL+PLC surgeries were the same. However, professional footballers with combined ACL+PLC surgery return at a lower rate and require a longer RTP time when compared to the ones with isolated ACL-R or combined ACL+MCL surgery. For the factors assessed in this study additional MCL surgery to ACL-R alone did not alter outcome from that with ACL-R in professional soccer players

Introduction. To determine if elite athletes can return to professional sport after MCL or posterolateral (PLC) reconstruction using LARS ligaments. The secondary aims are to demonstrate the safety and efficacy of LARS by reporting sport longevity, subsequent surgeries, and complications. Methods. A retrospective review of all extra-articular knee ligament reconstructions, utilising a LARS synthetic ligament, by 3 sports knee surgeons between 2013 and 2020 was undertaken. All elite athletes aged over 16 years and a minimum of 2 years post reconstruction were included. No LARS were used for ACL reconstructions, and they were excluded if a LARS ligament was used for a PCL reconstruction. Return to play (RTP) was defined as competing at professional level or national/ international level in amateur sport. Results. Sixty-four (84.2%) MCL reconstructions and 12 (15.8%) PLC reconstructions were included. 52 (68.4%) underwent concomitant autograft cruciate(s) reconstruction including 6 (7.8%) bicruciate reconstructions. The mean age was 25.1 years (SD +/− 4.50). 35 (46.1%) were footballers and 35 (46.1%) were rugby players. Sixty-seven athletes (88.2%) returned to elite sport, 7 (9.2%) did not RTP and RTP status was unknown for 2 (2.6%) (Figure 1). 65 out of 67 (97.0%) RTP at the same/higher Tegner level. 56 (83.6%) and 20 (57.1%) were still playing at 2- and 5-years post-surgery Six (7.9%) players required further surgery due to irritation from the metal fixation implants. One had an inflammation adjacent to the synthetic material at the femoral end and the other cases involved the tibial staples. All six cases were able to RTP. One athlete, following bicruciate /MCL surgery had the LARS removed due to laxity. There was one MCL re-rupture, sustained while jumping, 4 years after returning to football. Conclusions. Utilising LARS in extra-articular knee ligament reconstructions allows 88.2% of athletes with a variety of knee ligament injuries to return to elite sport. The results compare well regarding RTP, complication, and revision rates with the published evidence for other types of MCL and PLC grafts. This, coupled with 57% of athletes still playing 5 years post-surgery suggests the LARS is safe and effective in these cases. For any figures or tables, please contact authors directly

Background. Cam morphology develops during adolescence and predisposes individuals to future hip pain and osteoarthritis. An improved understanding of cam development is required to determine whether the process is modifiable. Hypothesis/Purpose. The aim of this study was to characterise the risk factors, timing, and pathogenesis of cam formation. Study Design. Longitudinal prospective observational cohort study. Methods. Longitudinal observational cohort study over three years of individuals from football club academies and an age-matched control population, aged 9–18 years at baseline. Assessments include questionnaires, clinical examination, and MRI of both hips. Alpha angle and epiphyseal extension were measured on radial images. Results. Cohort comprised male academy footballers (121 at baseline and 78 at follow-up) and male and female controls (107 at baseline and 71 at follow-up). Mean change in cartilage alpha angle was 12.4° (SD 8.4) for footballers, 7.3° (SD 6.0) for male controls and 4.0° (SD 4.1) for female controls. A positive correlation was found between Physical Activity Questionnaire Score and change in cartilage alpha angle (coefficient 0.787, p=<0.001). The greatest change in cartilage alpha angle occurred in individuals aged 11–12 years at baseline, with no significant change after 14 years of age. A positive correlation between mean cartilage alpha angle and lateral epiphyseal extension was observed (r. 2. = 0.294, p=0.029). Conclusions. Males undertaking intense sporting activity during adolescence at greatest risk of developing cam morphology, but there is no significant change in hip morphology after 14 years of age. The findings are consistent with physiological adaptation and epiphyseal extension in response to hip loading during skeletal immaturity
