Introduction. Anterior cruciate ligament (ACL) injuries are one of the most common knee injuries amongst elite athletes and usually require an ACL reconstruction (ACLR) to enable return to sport. Secondary surgery can result in a longer rehabilitation period and often a. significant time away from sport which can have implications to the athlete including contract obligations and sponsorship. Advances in ACLR techniques and meniscal repair techniques as well as an awareness of meniscal root lesions, ramp lesions and lateral extraarticular procedures (LEAPs) during ACL surgery has improved outcomes. The purpose of this study was to evaluate the rates of secondary surgery following the introduction of a systematic arthroscopic evaluation of the knee, improved meniscal repair techniques and the addition of a concomitant LEAP This systematic approach was introduced after October 2012 (10/2012). Methods. Professional athletes who underwent primary ACLR with a minimum follow-up of 2 years were identified from the (blinded for review). Those who had undergone major concomitant procedures such as multi-ligament reconstruction or osteotomy were excluded. Analysis of the database and review of medical records identified athletes who had underwent secondary surgery procedures. Results. A total of 342 athletes with a mean follow-up of 100.2 +/− 51.9 months (range, 24–215 months) were analysed. 130 athletes underwent surgery before 10/2012 and 212 athletes underwent surgery after 10/2012. Overall, 74 patients (21.6%) underwent secondary surgery. 39 patients (30.0% including 13.1% for graft rupture) before 10/2012 and 35 patients (16.5% including 6.6% for graft rupture) after 10/2012. A multivariate analysis was performed using the Cox model and demonstrated that athletes undergoing ACLR before10/2012 were at almost 2-fold risk of secondary surgery (hazard ratio (HR), 1.768(1.103;2.836), p=0.0256) when compared with those undergoing ACLR after 10/2012. (Figure 1). Conclusion. Professional athletes undergoing ACLR with a systematic arthroscopic evaluation with the use of advanced meniscal repair techniques and the combination with a LEAP result in a significantly lower rate of secondary surgery.

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

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. The Tour de France, commonly recognised and the hardest physical endurance event on the planet, is an iconic cycling competition with a history of ever impressive performances and increasingly notable injuries. This study aims to methodologically catalogue and analyse injuries sustained by professional riders over a span of six years and understand the operative workload created by this prestigious race. (2018–2023). Methods. Data was gathered from multiple publicly available sources, including pro-cycling stats, news articles, team press releases and independent medical reports. Each injury was categorized by year, rider, and injury type. Results. From 2018–2023, there was a significant diversity in both injured body part and mechanism of injury. Of the 124 recorded race ending incidents clavicle fractures accounted 19.4%, laceration/contusions 12.1%, patella fractures 10.5% and elbow fractures 7.3%. Other. notable other body areas undergoing surgical intervention were hand fractures 5.6%, pelvic fractures 2.4% and femoral fracture 1.6%. At a mean of 20.67 injuries per tour, this accounts for almost exactly one race ending injury per day where an athlete finishes the day on the operating table, rather than the team bus. Discussion. The Tour de France's rigorous challenges are mirrored in its injury statistics. Over six years, clavicle fractures were most prevalent, likely due to cyclists' instinct to brace during crashes. Lacerations, contusions, and patella fractures also featured prominently. Alarmingly, each race stage averaged an injury severe enough for surgical intervention. This data highlights the imperative need for enhanced protective measures, race regulations, and medical preparedness to protect these elite athletes

Introduction. Anterior Cruciate Ligament (ACL) injury prevention programs can reduce injury risk in various sports. The perception of ACL injury prevention programs amongst professional netball players and coaches has not been studied. The purpose of the study was to determine (1) level of awareness and experience of ACL injury prevention programs; (2) use of ACL injury prevention programs; and (3) barriers and potential facilitators to implementing a sustainable ACL injury prevention program in netball. Methods. This cross-sectional observational study was undertaken using the CHERRIES checklist. Female netball players representing Welsh senior and under-21 teams and elite and amateur coaches were invited electronically to participate in this web-based study between 1st May – 31st July 2021. Information on ACL injury susceptibility and seriousness, knowledge, experience, and implementation of ACL injury prevention programs were ascertained. Results. Twenty-eight players (77.8%) and 29 coaches (13.2%) completed the questionnaire. Seventeen (60.7%) players and 15 (51.7%) coaches reported female athletes were at greater risk for sustaining ACL injuries. Over 90% of respondents identified netball as high-risk, whilst 89% of players and 76% of coaches reported these injuries to be preventable. Only two (7.1%) players and 6 (20.7%) coaches utilised an ACL injury prevention program with lack of time and engagement from coaches and players identified. Majority of respondents indicated that their club has neither promoted, advocated the use nor demonstrated exercises for ACL injury prevention. Over 90% of respondents would utilise an ACL injury prevention program if it minimised players risk with appropriate information and demonstration of exercises. Conclusion. This study highlights limited knowledge of female athletes' increased susceptibility of ACL injuries amongst players and coaches with lack of communication and education of ACL injury prevention programs between sporting associations, coaches, and players. However, the results demonstrate willingness amongst both players and coaches to implement an ACL injury prevention program in netball

Aims

The free latissimus dorsi muscle (LDM) flap represents a workhorse procedure in the field of trauma and plastic surgery. However, only a small number of studies have examined this large group of patients with regard to the morbidity of flap harvest. The aim of this prospective study was therefore to objectively investigate the morbidity of a free LDM flap.

Aims

Tobacco, in addition to being one of the greatest public health threats facing our world, is believed to have deleterious effects on bone metabolism and especially on bone healing. It has been described in the literature that patients who smoke are approximately twice as likely to develop a nonunion following a non-specific bone fracture. For clavicle fractures, this risk is unclear, as is the impact that such a complication might have on the initial management of these fractures.

Aims

The primary aim of this study was to determine the rates of return to work (RTW) and sport (RTS) following a humeral shaft fracture. The secondary aim was to identify factors independently associated with failure to RTW or RTS.

Aims

It is unclear whether acute plate fixation facilitates earlier return of normal shoulder function following a displaced mid-shaft clavicular fracture compared with nonoperative management when union occurs. The primary aim of this study was to establish whether acute plate fixation was associated with a greater return of normal shoulder function when compared with nonoperative management in patients who unite their fractures. The secondary aim was to investigate whether there were identifiable predictors associated with return of normal shoulder function in patients who achieve union with nonoperative management.

Introduction. Multiple ACL revisions represent an extremely demanding surgery, due to the presence of enlarged or malpositioned tunnels, hardware, injuries to the secondary stabilizers and difficulties in retrieving autologous tendons. An anatomical ACL reconstruction is not always possible. We analyzed the results in a series of patients operated with over the top reconstruction (OTTR) and lateral extra-articular plasty to the Gerdy's tubercle (LP) using Achilles (AT) or tibialis posterior tendon (TPT) allografts. Methods. From 2002 to 2008, twenty-four male athletes with a mean age of 30.8 years were operated. 20 of the patients had two, while four patients had three previous reconstructions. IKDC score and KT evaluation were used at a mean 3.3 years follow-up (2–7 years). Results. The mean IKDC subjective score at follow-up was 81.3. The IKDC objective score rated A or B in 84% of the patients. Of the 20 good results, 17 patients resumed sport activity at the pre-injury level. KT side-to-side difference averaged 3.5 mm in the TPT, versus 3.2 mm in the AT group. No significant differences were noted between the AT and TPT group. Conclusions. Multiple ACL revision surgery is a salvage procedure, with average good results, but not equivalent to primary ACL reconstruction. Patients should be advised that a return to sports may not be feasible. OTTR+LP is an established technique that permits to overcome difficult anatomical situations, with cortical fixation providing good immediate stability and avoiding tunnel fixation and bone grafting. Long tendon grafts as AT and TPT are needed

Aims

There is a lack of long-term data for minimally invasive acromioclavicular (AC) joint repair. Furthermore, it is not clear if good early clinical results can be maintained over time. The purpose of this study was to report long-term results of minimally invasive AC joint reconstruction (MINAR) and compare it to corresponding short-term data.

Aims

The aim of this study was to compare the incidence of anterior knee pain after antegrade tibial nailing using suprapatellar and infrapatellar surgical approaches

This article presents a unified clinical theory that links established facts about the physiology of bone and homeostasis, with those involved in the healing of fractures and the development of nonunion. The key to this theory is the concept that the tissue that forms in and around a fracture should be considered a specific functional entity. This ‘bone-healing unit’ produces a physiological response to its biological and mechanical environment, which leads to the normal healing of bone. This tissue responds to mechanical forces and functions according to Wolff’s law, Perren’s strain theory and Frost’s concept of the “mechanostat”. In response to the local mechanical environment, the bone-healing unit normally changes with time, producing different tissues that can tolerate various levels of strain. The normal result is the formation of bone that bridges the fracture – healing by callus. Nonunion occurs when the bone-healing unit fails either due to mechanical or biological problems or a combination of both. In clinical practice, the majority of nonunions are due to mechanical problems with instability, resulting in too much strain at the fracture site. In most nonunions, there is an intact bone-healing unit. We suggest that this maintains its biological potential to heal, but fails to function due to the mechanical conditions. The theory predicts the healing pattern of multifragmentary fractures and the observed morphological characteristics of different nonunions. It suggests that the majority of nonunions will heal if the correct mechanical environment is produced by surgery, without the need for biological adjuncts such as autologous bone graft.

The purpose of this study was to describe the anatomical distribution and incidence of fatigue injuries of the femur in physically-active young adults, based upon MRI studies. During a period of 70 months, 1857 patients with exercise-induced pain in the femur underwent MRI of the pelvis, hips, femora, and/or knees.

Of these, 170 patients had a total of 185 fatigue injuries, giving an incidence of 199 per 100 000 person-years. Bilateral injuries occurred in 9% of patients. The three most common sites affected were the femoral neck (50%), the condylar area (24%) and the proximal shaft (18%). A fatigue reaction was seen in 57%, and a fracture line in 22%. There was a statistical correlation between the severity of the fatigue injury and the duration of pain (p = 0.001). The location of the pain was normally at the site of the fatigue injury. Fatigue injuries of the femur appear to be relatively common in physically-active patients.
