Common sports injuries include bone stress injuries (BSI), anterior cruciate ligament injuries (ACL), and concussions. Less commonly recognized are the specific sex differences in epidemiology, risk factors, and outcomes of these conditions by sex. An understanding of these factors can improve their clinical management, from prescribing appropriate prehabilitation to guiding post injury rehabilitation and return to play. This narrative review summarizes the sex differences in the diagnosis and management of BSI, ACL injuries, and concussions...

BACKGROUND: Surgery for athletic pubalgia usually consists in abdominal wall repair combined with routine bilateral adductor tenotomy. We currently confine the surgical procedure to the injured structure(s) (abdominal wall only, adductor tendon only, or both) to limit morbidity and expedite recovery. Outcomes of this à la carte approach are unclear. The objectives of this retrospective study were to determine the return to play (RTP) time, evaluate the potential influence of injury location, and assess the frequency of recurrence or contralateral involvement...

Perhaps as a consequence of increased specialism in training and support, the focus on engendering and maintaining agility as a generic quality has diminished within many contemporary sports performance programmes. Reflecting this, we outline a rationale suggesting that such a decreased focus represents an oversight which may be detrimental to maximising the potential of performers. We present an evidence-based argument that both generic and specific elements of agility performance should be consistently emphasised within long-term performance-training programmes...

OBJECTIVE: Concussions can result in auditory processing deficits even in the absence of hearing loss. In children and adolescents, the extent to which these impairments have functional consequences for everyday listening, such as the ability to understand speech in noisy environments, is unknown. RESEARCH DESIGN: Case-control study. SUBJECTS AND METHODS: Forty youth comprised the participants: 20 had sustained a concussion and were recovering from their injury, and 20 controls had sustained non-concussive orthopaedic (e...

PURPOSE: Anterior cruciate ligament (ACL) rupture commonly occurs in conjunction with articular cartilage injury. However, there is no consensus on the most appropriate rehabilitation which should be carried out for ACL reconstruction (ACLR) and the surgical management of articular cartilage lesions of the knee. The purpose of this study was to systematically review the literature to investigate the recommended rehabilitation protocol for patients undergoing ACLR with concomitant articular cartilage injury with a view to develop guidelines on the most appropriate treatment...

In contrast to anterior cruciate ligament reconstruction, there is a paucity of primary studies that address the issue of return to play after anterior shoulder stabilization for glenohumeral instability. Most studies focused on clinical outcomes after anterior shoulder stabilization provide little detail on the authors' assessment protocols used in determining return to sport readiness. In fact, many issues germane to the postoperative rehabilitation process (biologic healing, motion recovery, strength recovery, and sport-specific considerations) remain poorly defined, and are not typically addressed using validated shoulder outcomes instruments...

Background: Although much literature exists regarding the treatment and management of elbow dislocations in the general population, little information is available regarding management in the athletic population. Furthermore, no literature is available regarding the postinjury treatment and timing of return to play in the contact or professional athlete. Purpose: To review the clinical course of elbow dislocations in professional football players and determine the timing of return to full participation...

Background: Reconstruction of the anterior cruciate ligament (ACL) in the skeletally immature patient is frequently performed in hopes of preventing new or additional chondral damage and meniscal injuries. Patients within a few years of skeletal maturity are more at risk for ACL injuries than prepubescent patients, about whom several physeal-sparing techniques have been described. Reconstruction techniques in the former higher risk group need to be better understood. Purpose: To review a series of adolescent patients with ACL injuries surgically treated with the hybrid physeal-sparing technique...

PURPOSE: The purpose of our study was to evaluate return to play and postinjury performance of professional catchers who sustained an ulnar collateral ligament (UCL) rupture requiring surgical reconstruction. We looked to evaluate these players to determine the rate of return to play, the level of return to play, and career longevity after surgery as well as how statistical performance is affected by reconstruction. METHODS: Twenty-five professional catchers who underwent UCL reconstruction between 1985 and 2015 were identified and compared with an age-, position-, and competition-matched control group...

Background: Ulnar collateral ligament (UCL) injuries have increased significantly in recent years, and reconstruction has become the preferred treatment for UCL injury over ligament repair. In a recent study, UCL repair with internal bracing demonstrated significantly greater resistance to gap formation in biomechanical tests, even at low cycles of valgus loading. Purpose/Hypothesis: The purpose of this study was to compare the fatigue and failure mechanics of traditional UCL reconstruction with UCL repair and internal bracing...

BACKGROUND: Fifth metatarsal base fractures of the metaphyseal-diaphyseal watershed junction (Jones fracture) are commonly treated with surgical fixation in athletes. Intramedullary screw fixation remains the most utilized construct, although plantar-lateral plating is an alternative. Purpose/Hypothesis: The purpose was to compare the mechanical strength of fracture fixation between an intramedullary screw and plantar-lateral plating. The hypothesis was that plantar-lateral plate fixation would allow for more cycles and higher peak loads before failure, as well as less fracture gapping, than would an intramedullary screw in cadaveric foot specimens with simulated Jones fractures exposed to cantilever bending...

Sports concussions are recognized as significant injuries among young athletes. Research demonstrates that return-to-play prior to becoming asymptomatic has significant repercussions including sustained cognitive deficits. Many programs have begun to use computerized testing rather than traditional neuropsychological tests to (a) determine baseline performance, (b) track symptoms, and (c) measure symptoms following concussion. Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is one such tool...
