There is a disparity in sport-related injuries between sexes, with females sustaining non-contact musculoskeletal injuries at a higher rate. Anterior cruciate ligament ruptures are between two and eight times more common than in males, and females also have a higher incidence of ankle sprains, patellofemoral pain, and bone stress injuries. The sequelae of such injuries can be devastating to an athlete, resulting in time out of sport, surgery, and the early onset of osteoarthritis. It is important to identify the causes of this disparity and introduce prevention programmes to reduce the incidence of these injuries. A natural difference reflects the effect of reproductive hormones in females, which have receptors in certain musculoskeletal tissues. Relaxin increases ligamentous laxity. Oestrogen decreases the synthesis of collagen and progesterone does the opposite. Insufficient diet and intensive training can lead to menstrual irregularities, which are common in female athletes and result in injury, whereas oral contraception may have a protective effect against certain injuries. It is important for coaches, physiotherapists, nutritionists, doctors, and athletes to be aware of these issues and to implement preventive measures. This annotation explores the relationship between the menstrual cycle and orthopaedic sports injuries in pre-menopausal females, and proposes recommendations to mitigate the risk of sustaining these injuries.

Aims. To determine whether an early return to sport in professional Australian Rules Football players after fixation of a non-thumb metacarpal fracture was safe and effective. Patients and Methods. A total of 16 patients with a mean age of 25 years (19 to 30) identified as having a non-thumb metacarpal fracture underwent open reduction and internal plate and screw fixation. We compared the players’ professional performance statistics before and after the injury to determine whether there was any deterioration in their post-operative performance. Results. Of the 16, 12 sustained their fracture during the season: their mean time to return to unrestricted professional play was two weeks (1 to 5). All except two of the 48 player performance variables showed no reduction in performance post-operatively. Conclusion. Our data suggest that professional athletes who sustained a non-thumb metacarpal fracture can safely return to professional play without restriction two weeks after internal fixation.

The anterior cruciate ligament (ACL) is frequently injured in elite athletes, with females up to eight times more likely to suffer an ACL tear than males. Biomechanical and hormonal factors have been thoroughly investigated; however, there remain unknown factors that need investigation. The mechanism of injury differs between males and females, and anatomical differences contribute significantly to the increased risk in females. Hormonal factors, both endogenous and exogenous, play a role in ACL laxity and may modify the risk of injury. However, data are still limited, and research involving oral contraceptives is potentially associated with methodological and ethical problems. Such characteristics can also influence the outcome after ACL reconstruction, with higher failure rates in females linked to a smaller diameter of the graft, especially in athletes aged < 21 years. The addition of a lateral extra-articular tenodesis can improve the outcomes after ACL reconstruction and reduce the risk of failure, and it should be routinely considered in young elite athletes. Sex-specific environmental differences can also contribute to the increased risk of injury, with more limited access to and availablility of advanced training facilities for female athletes. In addition, football kits are designed for male players, and increased attention should be focused on improving the quality of pitches, as female leagues usually play the day after male leagues. The kit, including boots, the length of studs, and the footballs themselves, should be tailored to the needs and body shapes of female athletes. Specific physiotherapy programmes and training protocols have yielded remarkable results in reducing the risk of injury, and these should be extended to school-age athletes. Finally, psychological factors should not be overlooked, with females’ greater fear of re-injury and lack of confidence in their knee compromising their return to sport after ACL injury. Both intrinsic and extrinsic factors should be recognized and addressed to optimize the training programmes which are designed to prevent injury, and improve our understanding of these injuries.

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

Aims. The ideal management of acute syndesmotic injuries in elite athletes is controversial. Among several treatment methods used to stabilize the syndesmosis and facilitate healing of the ligaments, the use of suture tape (InternalBrace) has previously been described. The purpose of this study was to analyze the functional outcome, including American Orthopaedic Foot & Ankle Society (AOFAS) scores, knee-to-wall measurements, and the time to return to play in days, of unstable syndesmotic injuries treated with the use of the InternalBrace in elite athletes. Methods. Data on a consecutive group of elite athletes who underwent isolated reconstruction of the anterior inferior tibiofibular ligament using the InternalBrace were collected prospectively. Our patient group consisted of 19 elite male athletes with a mean age of 24.5 years (17 to 52). Isolated injuries were seen in 12 patients while associated injuries were found in seven patients (fibular fracture, medial malleolus fracture, anterior talofibular ligament rupture, and posterior malleolus fracture). All patients had a minimum follow-up period of 17 months (mean 27 months (17 to 35)). Results. All patients returned to their pre-injury level of sports activities. One patient developed a delayed union of the medial malleolus. The mean return to play was 62 days (49 to 84) for isolated injuries, while the patients with concomitant injuries returned to play in a mean of 104 days (56 to 196). The AOFAS score returned to 100 postoperatively in all patients. Knee-to-wall measurements were the same as the contralateral side in 18 patients, while one patient lacked 2 cm compared to the contralateral side. Conclusion. This study suggests the use of the InternalBrace in the management of unstable syndesmotic injuries offers an alternative method of stabilization, with good short-term results, including early return to sports in elite athletes.

The spectrum of pathoanatomy in collision athletes with shoulder instability is wide, with a high incidence of extended labral lesions and associated intra-articular injuries. The ‘collision shoulder’ describes an injury sustained by direct impact to the shoulder without dislocation, but with extensive labral damage and a high incidence of other intra-articular pathology and neurological symptoms. One hundred and eighty-three collision athletes (rugby and rugby league) were treated for labral injuries related to their sport in three different centres. Details of the mechanism of injury and findings at surgery were recorded. Only 60% of athletes in the series presented following a documented dislocation or subluxation episode of the shoulder. An additional pattern of injury was recognised in the remaining athletes involving a direct impact injury to the shoulder. In these athletes the clinical symptoms and signs were less specific but there was a high incidence of ‘dead arm’ at the time of injury (72%). The spectrum of pathology in this series was wide with a high incidence of associated intra-articular lesions. In those athletes with an impact type of injury without dislocation there was more extensive labral pathology with a high incidence of posterior labral tears (50%). The incidence of associated chondral lesions was similarly very high but significant bony pathology was less common than in the dislocation group (11 % versus 26%). Elite athletes had less frank dislocations but were more likely to sustain neurological injury, posterior labral tears, SLAP lesions and cartilaginous and capsular injuries. The incidence of all lesions in this series of collision athletes is higher than those previously published. These lesions often occurred in the absence of a frank dislocation (the ‘collision shoulder). It is important to anticipate additional pathology when planning definitive management in these patients, with surgery tailored to the specific lesions found. The athlete with an impact type of injury without dislocation can do well following surgery, with a high rate of return to contact sport, either at the same or a higher level

Aim. The aim of this study was to assess the role of hip arthroscopy in the management of hip pain in elite athletes. Patients and methods. It is a retrospective study of prospectively collected data. 31 hip arthroscopies were performed on 27 elite athletes. All the patients were assessed pre-operatively with a thorough clinical examination, radiographs and MRI scans. The modified HHS was also recorded for all the patients' pre and post-operatively. All operations were performed by the senior author, and the patients were assessed at 6 weeks, 3 months, 6 months and a year following the operation. Results. The M:F ratio was 25:2 with an average age of 38 years (Range: 18-58) in the study group. 65% of the patients were professional football players followed by cricket and tennis. The patients were referred at an average of 506 days. Two of the 27 patients demonstrated minimal acetabular dysplasia on their pre-operative radiographs. Of the 31 arthroscopies, a primary diagnosis of a labral tear was made in 20, a chondral flap and delamination in 5, early osteoarthritis in 4 and a ligamentum teres tear in 2. Along with the primary diagnosis of a labral tear, twelve of the 20 patients had a secondary diagnosis of chondral injury and or Femeroacetabular Impingement as well. There were no complications reported. Conclusions. Hip Injuries in athletes are reported late and Chondral Flaps and Ligamentum teres tears are under-diagnosed. Most athletes have a good chance to return back to the original level of sport within 4 months following hip arthroscopy. However, about 40% do continue to have some form of pain. Hip arthroscopy is a safe and effective method for diagnosis and treatment of intra-articular disorders in elite athletes

Background. Lateral ligament injuries of the ankle are common. They account for up to 50% of all sporting injuries. Recovery times vary, leading to time away from sport and training for the professional athlete. Predicting this time is important for the treating surgeon, the athlete and the rehabilitation team. This can be difficult as associated ankle injuries occurring at the time of the trauma may alter recovery and rehabilitation. Aim. To compare the time to return to training and sports of isolated lateral ligament injuries with more complex injuries of the ankle treated surgically and to evaluate if lateral ligament repair is safe and effective in the professional athlete. Study design: Case series; level of evidence 4. Methods. A consecutive series of professional sportsmen and women were treated operatively for radiologically and clinically confirmed grade III lateral ligament injury between 2005 and 2009. The patients were split into two groups; isolated lateral ligament injuries and those with other associated injuries. The end points studied were the time to return to training in weeks and the time to return to play in weeks. Results. There were 26 ankles in 26 patients. 16 were isolated injuries (Group A) and 10 had associated injuries (Group B). The associated injuries included, osteochondral defects (OCD) (3), deltoid ligament injury (5), syndesmotic injury (1) and deltoid ligament injury combined with an OCD (1). The mean time to return to training in group A was 61.3 days (range 55–110) and in group B was 99.5 days (63–152). The mean time to return to play in Group A was 78.2 days (range 63–127) and group B 116.7 days (82–178). The time to return to training and play was significantly shorter for the isolated lateral ligament injury group, (p=0.0003) and (p=0.0004) respectively. The only complications were two minor wound infections that responded to oral antibiotics. No patient returned for recurrent instability and all returned to their pre-injury level of play. Conclusion. Lateral ligament repair was a successful and safe procedure leading to return to pre-injury level of play for all the athletes. Time to return to training and play was significantly shorter if there were no associated injuries to the ankle. NO DISCLOSURES

Aims. The aim of this study was to report the outcome of the non-operative treatment of high-grade posterior cruciate ligament (PCL) injuries, particularly Hughston grade III injuries, which have not previously been described. Patients and Methods. This was a prospective study involving 46 consecutive patients who were athletes with MRI-confirmed isolated PCL injuries presenting within four weeks of injury. All had Hughston grade II (25 athletes) or III (21 athletes) injuries. Our non-operative treatment regimen involved initial bracing, followed by an individualised rehabilitation programme determined by the symptoms and physical signs. The patients were reviewed until they had returned to sports-specific training, and were reviewed again at a mean of 5.2 years (3 to 9). Results. The mean time to return to sports-specific training was 10.6 weeks and the mean time to return to full competitive sport was 16.4 weeks (10 to 40). A total of 42 patients (91.3%) were playing at the same or higher level of sport two years after the injury, with a mean Tegner activity score of 9 (5 to 10). At five years, 32 patients (69.5%) were playing at the same or higher level of sport, and 38 patients (82.6%) were playing at a competitive level, with a mean Tegner activity score of 9 (5 to 10). Conclusions. Medium-term review of a series of athletes suggests that commencing the non-operative management of isolated, Hughston grade II and III PCL injuries within four weeks of injury gives excellent functional outcomes with a high proportion returning to the same or higher level of sport.

Background:. Achilles pathology is a serious and frequently occurring problem, especially in elite athletes. Recent research has suggested a role for the plantaris tendon in non-insertional achilles tendinopathy. We report on the outcomes after excision of the plantaris tendon in elite athletes. Aim:. To assess whether or not excising the plantaris tendon improves the symptoms of Achilles tendinopathy in elite athletes. Methods:. A group of 32 elite athletes who underwent plantaris tendon excision to treat medially located pain associated with non-insertional Achilles tendinopathy were investigated. Outcomes were assessed with pre and post-operative Visual Analogue Scores (VAS) for pain and the Foot and Ankle Outcome Score (FAOS) as well as time to return to sport and satisfaction scores. Results:. At a mean follow-up of 22.4 months (12–48), 29/32 (90%) of athletes were satisfied with the results. 30/32 athletes (94%) returned to sport at a mean of 10.3 weeks (5–27). The mean VAS score improved from 5.8 to 0.8 (p<0.01) and the mean FAOS improved in all domains (p<0.01). Conclusions:. The plantaris tendon may be responsible for symptoms in some patients with non-insertional Achilles tendinopathy. Excision using a mini-incision technique carries a low risk of complications and may provide significant improvement in symptoms enabling an early return to elite level sports

Pain in front of the knee is common in athletes and is often called patellofemoral arthralgia, but it is difficult to prove that the pain arises in that joint. Thermograms of 30 athletes clinically considered to have patellofemoral arthralgia were compared with those of a similar number of unaffected athletes matched for age and sex. A comparison was also made with thermograms of two older groups of 30 patients with knee involvement from either rheumatoid arthritis or osteoarthritis. Twenty-eight of the athletes with patellofemoral arthralgia had a diagnostic pattern on thermography. The anterior knee view showed a rise in temperature on the medial side of the patella and the medialis knee view showed that this temperature rise radiated from the patellar insertion of the vastus medialis into the muscle itself. The possible aetiological role of quadriceps muscle imbalance in athletes with patellofemoral arthralgia is discussed in relation to these findings

We document intra-articular pathology in collision athletes with shoulder instability and describe the ‘collision shoulder’ – a direct impact without dislocation, with unusual labral injury, significant intra-articular pathology and neurology. 183 collision athletes were treated for labral injuries in 3 centres. Details of injury mechanism and intra-articular pathology at surgery were recorded. Premier league and International (Elite) comprised 72 players. A tackle was implicated in 52% of injuries and 65% had a dislocation. The mechanism of injury was ABduction External Rotation (ABER) in 45%, direct impact 36%, abduction only 8% and axial load 6%. Dislocation occurred in 51% of shoulders with ABER mechanism. A Bankart lesion was found in 79% of these shoulders; Hill-Sachs in 58% and Bony Bankart in 26%. Inferoposterior labral tears were present in only 11%, Superior Labral Antero-Posterior (SLAP) lesions in 32% and partial injury to the rotator cuff in 32%. In those sustaining a direct impact to the shoulder, 61% did not document dislocation, had a high incidence of inferoposterior labral involvement (50%), neurological symptoms (32%), but a low incidence of Bankart (33%), Hill-Sachs (22%) and Bony Bankart (11%) lesions. The mechanism did not affect incidence of superior labral/SLAP tears (18%), or capsular tears (including Humeral Avulsion of Glenohumeral Ligaments – HAGL) – 15%. Elite athletes had less dislocations (43% vs 74%) irrespective of mechanism, but were 40% more likely to have neurology, posteroinferior labral, cartilaginous or capsular injuries. They had twice the incidence of Bony Bankart and rotator cuff lesions and 5 times more SLAP/superior labral tears. Collision athletes with shoulder instability have a wide spectrum of pathoanatomy of the labrum and frequent associated intra-articular lesions. Significant injury often occurs in the Elite athlete and those sustaining a direct hit without dislocation (the ‘Collision Shoulder’)

Aims. The use of biologics in the treatment of musculoskeletal injuries in Olympic and professional athletes appears to be increasing. There are no studies which currently map the extent, range, and nature of existing literature concerning the use and efficacy of such therapies in this arena. The objective of this scoping review is to map the available evidence regarding the use of biologics in the treatment of musculoskeletal injuries in Olympic and professional sport. Methods. Best-practice methodological frameworks suggested by Arksey and O’Malley, Levac et al, and the Joanna Briggs Institute will be used. This scoping review will aim to firstly map the current extent, range, and nature of evidence for biologic strategies to treat injuries in professional and Olympic sport; secondly, to summarize and disseminate existing research findings; and thirdly, to identify gaps in existing literature. A three-step search strategy will identify peer reviewed and non-peer reviewed literature, including reviews, original research, and both published and unpublished (‘grey’) literature. An initial limited search will identify suitable search terms, followed by a search of five electronic databases (MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Web of Science, and Google Scholar) using keyword and index terms. Studies will be screened independently by two reviewers for final inclusion. Dissemination. We will chart key concepts and evidence, and disseminate existing research findings to practitioners and clinicians, through both peer reviewed and non-peer reviewed literature, online platforms (including social media), conference, and in-person communications. We will identify gaps in current literature and priorities for further study

We present a case of L2/3 interspinous bursitis treated with extraspinal injections. No previous investigations have used fluoroscopically guided spinal injections to confirm the clinical relevance of the MRI features of this type of bursae. Autopsy studies have revealed an increased incidence of interspinous lumbar bursal cavities with advancing age. Afflicted patients present with localised, midline lower lumbar pain exacerbated by extension. In young athletes these symptoms can mimic spondylolysis. MRI is useful in detecting soft-tissue injury of the posterior elements. Fluoroscopically guided diagnostic and therapeutic extraspinal injections can be used for confirmation and treatment of pain from such bursae

Purpose: Shoulder pain in the young athlete is often a diagnostic challenge. It is our experience that this pain can be related to a so-called “unstable painful shoulder” (UPS), defined as instability presenting in a purely painful form, without any history of instability but with anatomical (soft tissue or bony) ‘roll-over’ lesions. The objectives are to describe the epidemiology and diagnostic criteria and to report the results of surgical treatment. Method: A prospective review was performed of 20 patients (mean age 22 ± 8 years). Inclusion criteria: a painful shoulder and “roll-over lesions” on imaging or at surgery. Exclusion criteria: a dislocation/subluxation; associated pathology; previous shoulder surgery. Results: Most patients were male (60%), athletes (85%) and involved the dominant arm (80%). All patients denied a feeling of instability and only complained of deep, anterior pain. Most had a history of trauma (80%). All patients had rehabilitation without success and 30% had subacromial injections. All had to stop sports. Most (85%) had anterior or inferior hyperlaxity. All had pain with an anterior apprehension test and relieved by relocation test. ‘Roll-over’ lesions included: labrum detachment (90%), capsular distension (75%), HAGL lesion (10%), glenoid fracture (20%) or Hill-Sachs (40%). Time from symptoms to surgery was 25 ± 23 months. All patients had arthroscopic treatment. Mean follow-up was 38 ± 14 months. Eighteen patients (90%) were very satisfied/satisfied. None had pain at rest, but one (5%) had pain with apprehension test. There was no change in elevation, external or internal rotation (p> 0.05). There were no cases of instability. Rowe and Duplay scores improved (p< 0.05). Conclusion: Instability of the shoulder can present in a purely painful form, without any history of dislocations or subluxations. Diagnosis can be difficult, and should be suspected in young patients and athletes. Most patients have deep anterior pain and pain with apprehension test. ‘Roll-over’ lesions are necessary to confirm the diagnosis. Arthroscopic repair is effective

We have an aggressive approach to meniscal repair, including repairing tears other than those classically suited to repair. Elite athletes represent the subgroup of patients who place the most demand on the menisci and as a result, place maximum stress on any meniscal repair. Here we present the medium to long-term outcome of meniscal repair (inside-out) in the elite athlete. 42 elite athletes underwent 45 meniscal repairs between January 1990 and July 1997 were identified from a prospective database. All repairs were performed using an arthroscopically assisted inside-out technique. All patients returned a completed questionnaire (Lysholm and IKDC) to determine their current function and any symptoms or interventions that we were unaware of. 67% medial and 33% lateral menisci were repaired (3 patients had both medial and lateral menisci repaired). 83.3% of these repairs were associated with simultaneous ACL reconstruction. The average time from injury to surgery was 11 months (range 0–45 months). Follow-up time was a mean of 8.5 years (range 5.4 to 12.6 years). In general, function was good with an average Lysholm and subjective IKDC scores of 89.6 and 85.4 respectively. 81% of patients returned to their main sport and most to a similar level at a mean time of 10.4 months post-repair. We identified 11 definite failures, 10 medial and 1 lateral meniscus that ultimately required arthroscopic excision, this represents a 24% failure rate. We identified one further patient who had possible failed repairs, giving a worse case failure rate of 26.7% at a mean of 42 months post surgery. However, 7 of these failures were associated with a further injury, and 2 of the 7 failures ruptured their ACL reconstruction. Therefore the repairs had healed and were torn with reinjury. In this series medial meniscal repairs were Significantly more likely to fail than lateral meniscal repairs, with a failure rate of 36.4% and 5.6% respectively (p< 0.05). This series reflects an aggressive approach to meniscal repair with repair of tears in a high demand elite group of patients. Despite this, on a worst case analysis 73% were intact at a mean of 8.5 years post repair. We conclude that meniscal repair and healing is possible and that most patients can return to preinjury level of activity

Background: There is abundant literature on the treatment of Achilles tendon rupture; however data on sports and recreational activities after this injury is scarce. Patients and Methods: 71 patients were assessed in a prospective cross-sectional study after an average of 3 years after Achilles tendon rupture. 44 patients were treated non-operatively, using a functional algorithm, and 23 patients were treated operatively. Outcome parameters were the AOFAS-Score and the SF-36 Score. The strength of plantar-flexion was measured using the Isomed 2000 system, the structural integrity of the tendon was assessed sonografically. Results: Patients treated operatively had a higher complication rate than patients treated non-operatively (p=0.05). Re-rupture rate was identically in both groups. No difference was noted between the two groups for the AOFAS score (92 vs. 90). Moreover the SF-36 score did not show any significant difference between the groups. However, if compared to the age-adjusted normative population significant lower scores were achieved. A significant reduction in practicing sports was detected, as well as a reduction of plantar flexion of the affected foot (p=0.04). Conclusion: Except for complication rate no significant difference could be detected between the groups. Thus operative treatment in the recreational athletes should only be considered, if no adaptation of the ends of the tendon is diagnosed during the initial or repeated ultrasound. Regardless of the therapeutic intervention chosen an Achilles tendon rupture leads to marked changes in sports- and recreational activities

Background. A large number of Tendo-Achilles (TA) injuries occur during sporting activity. Typically occurring in males aged 30–50, whom occasionally undertake sporting activities, the so called ‘weekend warriors’. Aims. To assess the impact of TA rupture on return to sporting activity in the non-elite athlete. Methods. Single unit 5 year retrospective analysis of TA rupture patients. Clinical notes were reviewed and a telephone interview was conducted using a designed questionnaire. Results. 68 patients were identified, 39 responded of which 25 were male and 14 were female. The mean age was 46 years with an age range of 17–77 years. Sporting activity was the major cause of rupture, causative in 27/39 patients, 84% of males and 43% of females. A third of patients had only just returned to the causative sport. In males, football contributed the most injuries, 48%, however for females, badminton contributed the highest number, 67%. 23 patients did not return to their pre-injury sporting activity level. Of these patients, 87% stopped the causative sport completely, 22% stopped sporting activity altogether with 78% returning to sport at a lower level, reducing both the intensity and variety. 20/23 of these patients were treated operatively. Reasons given for a reduction in sporting activity were a “real worry” of re-rupture, 83%, and a “loss of confidence” caused by the injury, 74%. Other reasons were related to pain in the Achilles, 65%, and “previous plans” to reduce level of activity anyway, 35%. Conclusion. Many patients cite the ability to return to sport as a reason for operative intervention. Our study highlights that many patients do not return to sports at all, with those that do, a significant number return at a lower level of intensity, irrespective of treatment. This information could be useful when assessing treatment options in the non-elite athlete

Subtalar dislocation of the hindfoot is a rare injury and can be associated with poor functional outcomes. We report a case of an irreducible subtalar dislocation in an elite athlete, who returned to elite sport. A 28 year old competitor in the world mountain bike championships was injured in a high speed fall from his mountain bike during a competitive downhill run in July 2007. He had an obvious deformity at the scene and a fracture dislocation of the ankle was suspected. The injury was closed and neuro-vascular status was intact. Radiographs revealed the ankle mortise was intact with the talus anatomical, but a subtalar dislocation was present which proved irreducible in the emergency department. The patient was taken to the operating theatre and the dislocation was reduced through a short antero-medial arthrotomy using a blunt lever and traction. Post- reduction, the joint was stable and was supported in a below knee cast. He was kept partial weight bearing for 6 weeks and then had an intensive physiotherapy rehabilitation regime. Serial radiology showed no evidence of avascular necrosis or other skeletal abnormalities. Our patient has since returned to elite Mountain Biking and won the British National Championships in 2008 and the World Championships in Canberra in 2009

We report the results of a prospective longitudinal study of 147 athletes who had had a meniscectomy for an isolated meniscus injury. The patients were reviewed in detail after median periods of 4.5 years and 14.5 years and the results analysed. The frequency of complaints related to the operation increased from 53% at 4.5 years to 67% at 14.5 years, while demonstrable knee instability increased from 10% to 36%. The incidence of radiographic changes of degeneration rose from 40% to 89% and at late review 8% of patients had definite osteoarthritis by the criteria of Ahlback (1968). In consequence 46% had given up or reduced their sporting activity, and 6.5% had changed their occupation. Radiographic deterioration started after the 4.5-year review in 49% of the patients and was more frequent after lateral than medial meniscectomy
