Purpose of review: Graft failure, one of the most common outcomes in anterior cruciate ligament reconstruction randomized controlled trials, lacks a consensus definition. The purpose of this study was to systematically summarize current practice and parameters in defining anterior cruciate ligament reconstruction graft 'failure'.

Recent findings: Forty studies (4466 participants) satisfied the inclusion criteria. Of these, 90% either defined failure formally or referenced the etiology of failure, the remaining 10% used the term failure without referencing the anterior cruciate ligament reconstruction graft. Among the included studies, there was a high level of inconsistency between the definitions of graft failure. The extracted data was categorized into broader groups, revealing abnormal knee laxity (80%) and graft re-rupture (37.5%) as the most common parameters incorporated in the definitions of graft failure in high-level randomized controlled trials. This review shows that anterior cruciate ligament reconstruction randomized controlled trials lack a consistent definition for graft failure. A universal definition is vital for clarity in medical practice and research, ideally incorporating both objective (e.g. graft re-rupture) and subjective (e.g. validated questionnaires) parameters. A composite outcome should be established which includes some of the common parameters highlighted in this review. In the future, this review can be used to assist orthopaedic surgeons to establish a formal definition of anterior cruciate ligament reconstruction graft 'failure'.

Purpose of review: The tibial tubercle osteotomy (TTO) is a versatile surgical technique used to treat a range of patellofemoral disorders, including patellar instability, painful malalignment, focal chondral defects, and patellar maltracking that have failed conservative therapies. TTO is a personalized procedure that can be tailored to the pathoanatomy of the patient based on physical examination and imaging. The complication rate associated with TTO strongly depends on the indication for surgery, the severity of the patient's condition, and the surgical approach. Despite the literature on TTO, to our knowledge, no single source has addressed the indications, techniques, outcomes, and complications of this procedure. The purpose of this article is to serve as such a valuable resource.

Recent findings: Highlights from recent studies we would like to emphasize are two-fold. First, maintaining a distal cortical hinge yields lower complication rates than osteotomies involving complete tubercle detachment with classic or standard techniques. Second, based on current evidence, TTO consistently provides symptomatic relief, and most patients can return to work or sport at their pre-operative level within 3 and 6 months, respectively. TTO is a personalizable surgical technique that may be utilized for multiple patellofemoral disorders and is associated with good outcomes.

Purpose of review: Healthcare disparities influence multiple dimensions of orthopaedic care including access, burden and incidence of disease, and outcome in varying populations. These disparities impact healthcare at both the micro and macro scale of the healthcare experience from individual patient-physician relationships to reimbursement rates across the United States. This article provides a review of how healthcare disparities contribute to the landscape of orthopaedic care and specifically highlights how disparities affect outpatient visits, discretionary and unplanned surgical care, and postoperative outcomes.

Recent findings: Current research demonstrates the widespread presence of healthcare disparities in the field of orthopaedics and gives both objective and subjective evidence confirming disparities' measurable influence. The disparities most highlighted by our review include differences in orthopaedic care based on insurance type and race. Currently disparities in orthopaedic care are deeply connected to patient insurance status and race. In the outpatient setting insurance significantly impacts access to care, travel burden, and utilization of services. The emergent setting is similarly influenced with measurable differences in lack of access to acute care, rates of inappropriate triage, and timeliness of care based on insurance status and race. Additionally, the postoperative period is not immune to disparities with likelihood of follow up, experience of catastrophic medical expenses, and postoperative outcomes also being affected. Addressing these disparities is a pressing need and may include solutions like wider expansion and acceptance of publicly funded insurance and the development of readily available and easily measurable metrics for healthcare equity and quality in vulnerable populations.

Purpose of review: The burden of musculoskeletal disease is increasing globally and disproportionately affecting people in low and middle income countries (LMIC). We sought to review global access to orthopaedic care, burden of trauma, research infrastructure, impact of surgical mission trips, implant availability, and the effect of COVID-19 upon the delivery of orthopaedic care worldwide.

Recent findings: The majority of people in LMIC do not have access to safe, quality surgical care, and there are few fellowship-trained orthopaedic traumatologists. Road traffic accidents are the leading cause of long bone fractures in LMIC and result in significant morbidity and mortality. Of the orthopaedic literature published globally in the last 10 years, less than 15% had authors from LMIC. There has been growth in surgical mission trips to LMIC, but few organizations have established bidirectional partnerships. Among the challenges to delivering quality musculoskeletal care in LMIC is timely access to quality orthopaedic implants. Implant options in LMIC are more limited and subjected to less rigorous testing and regulation than high income countries (HIC). The COVID-19 pandemic dramatically reduced elective surgeries but saw the increase in telemedicine utilization which has prevailed in both HIC and LMIC. Awareness of global inequities in orthopaedic care is growing. Much can be learned through collaborations between orthopaedic surgeons from HIC and LMIC to advance patient care worldwide. There is a need for high quality, accurate data regarding incidence and prevalence of musculoskeletal disease, care utilization/availability, and postoperative outcomes so resources can be allotted to make orthopaedic care more equitable globally.

Purpose of review: The aim of this review is to summarize information published in the recent peer-reviewed literature on reverse shoulder arthroplasty (RSA) for proximal humerus fractures.

Recent findings: Although there is still some debate regarding which may be the best treatment for proximal humerus fractures in certain age ranges, RSA seems to offer more predictable results than other surgical treatments for elderly patients. Successful tuberosity healing seems to correlate with better outcomes. Recent trends indicate interest in cementless fixation, fracture-specific stems and a 135-degree polyethylene opening angle. RSA provides a successful surgical solution for selected proximal humerus fractures. Indications, design features, and surgical execution have continued to evolve over the last few years.

Purpose of review: Hip injuries in elite athletes are an increasingly recognized problem and range from chronic overuse injuries, such as adductor strains and labral tears, to acute traumatic injuries such as hip dislocations. In this article, we review common hip pathology experienced by elite athletes and sideline management of emergent hip injuries.

Recent findings: Elite athletes are subject to unique physical and mental stresses and therefore must be evaluated and treated in a unique manner. Hip and groin injuries account for approximately 6% of sport injuries overall and 3-15% of all injuries in professional sports. Hip sideline emergencies were rare but can include hip dislocations, subluxations, and avulsion fractures. Hip and groin injuries represent an important subset of injuries which can greatly impact an athlete's ability to perform. Understanding the physiology and types of hip/groin injuries, which athletes are prone to injuries, the impact on recovery time, recurrence risk, and the potential need for surgery aid sports medicine physicians in decision-making.

Purpose of review: Adolescent wrestlers undergo intense physical combat. While guidelines are effective in keeping the sport safer, concerns specific to the adolescent wrestler may be missed at primary care visits without knowledge of the unique challenges faced by these athletes. The following review highlights important characteristics of the adolescent wrestler which are of interest to primary care providers.

Recent findings: Recommendations for concussion management are evolving to gradual return-to-sport after physician clearance rather than total sport removal. Prolonged skin-to-skin contact also places athletes at greater risk of dermatologic infections, which often require removal from competition, treatment, and/or coverage. Finally, adolescent nutritional literature recommends limiting pre-match weight loss to 3-5% body weight due to noted kidney damage that may result from larger deficits. Adolescent wrestlers are more prone to acute injuries than chronic overuse injuries, with most injuries occurring above the trunk. Primary care providers should consider obtaining imaging to rule out severe injuries or referring to specialist providers. Current guidelines for skin infections require frequent pre-match skin checks and mandatory waiting periods when certain infections are identified. However, the primary care provider is well-equipped for more in-depth skin examination, discussion of skin hygiene, and appropriate treatment of skin infections. Athletes attempting to meet lower weight classes may put themselves at risk of acute kidney damage, under-fueling, and eating disorders. Current guidelines attempt to mitigate excessive weight changes in the adolescent wrestler during competition season, but primary care providers should emphasize healthier methods of weight fluctuation and look for indicators of physiological or psychological effects.

Purpose of review: Platelet-rich plasma (PRP) is an emerging biological intervention for osteoarthritis (OA), yet the outcomes remain uncertain. The purpose of this study was to review current literature regarding the use of PRP for knee and hip OA.

Recent findings: Recent systematic reviews have found significant clinical improvements in outcomes after the administration of PRP compared to hyaluronic acid (HA) in patients with knee OA. One of these reviews included bone marrow aspirate concentrate (BMAC) as a comparison group and found no significant differences in outcomes between PRP and BMAC. Currently, the literature is lacking on whether leukocyte-rich or leukocyte-poor PRP is superior in patients with knee OA. The literature on PRP for hip OA has not provided consistent results as it has for the knee. Two recent systematic reviews evaluated RCTs for patients undergoing treatment with either PRP or HA for hip OA and found no significant differences in clinical outcomes between groups at final follow-up. Current literature regarding the association between OA grade and PRP efficacy has found varying results. The use of PRP injections in the treatment of knee OA appears to be favorable, resulting in clinically comparable or superior outcomes compared to other injection treatments. However, the clinical efficacy of PRP injections in hip OA is far less consistent. Evidence is lacking to suggest that the presence of leukocytes significantly influences clinical outcomes. Further randomized controlled trials on larger cohorts, with longer follow-up, and with comparable formulations are required before recommendations can be made regarding use of PRP for hip OA, the effect of leukocyte concentration, and clinical efficacy based on OA grade.

Purpose of review: The management of shoulder instability in throwing athletes remains a challenge given the delicate balance between physiologic shoulder laxity facilitating performance and the inherent need for shoulder stability. This review will discuss the evaluation and management of a throwing athlete with suspected instability with a focus on recent findings and developments.

Recent findings: The vast majority of throwing athletes with shoulder instability experience subtle microinstability as a result of repetitive microtrauma rather than episodes of gross instability. These athletes may present with arm pain, dead arms or reduced throwing velocity. Recent literature reinforces the fact that there is no "silver bullet" for the management of these athletes and an individualized, tailored approach to treatment is required. While initial nonoperative management remains the hallmark for treatment, the results of rehabilitation protocols are mixed, and some patients will ultimately undergo surgical stabilization. In these cases, it is imperative that the surgeon be judicious with the extent of surgical stabilization as overtightening of the glenohumeral joint is possible, which can adversely affect athlete performance. Managing shoulder instability in throwing athletes requires a thorough understanding of its physiologic and biomechanical underpinnings. Inconsistent results seen with surgical stabilization has led to a focus on nonoperative management for these athletes with surgery reserved for cases that fail to improve non-surgically. Overall, more high quality studies into the management of this challenging condition are warranted.

Purpose: Osteoporosis, the most prevalent metabolic bone disease, significantly impacts global public health by increasing fracture risks, particularly among post-menopausal women and the elderly. Osteoporosis is characterized by decreased bone mineral density (BMD) and deterioration of bone tissue, which leads to enhanced fragility. The disease is predominantly diagnosed using dual X-ray absorptiometry (DXA) and is significantly influenced by demographic factors such as age and hormonal changes. This chapter delves into the condition's complex nature, emphasizing the pervasive gender and racial disparities in its screening, diagnosis, and treatment.

Recent findings: Recent findings highlight a substantial gap in the management of osteoporosis, with many individuals remaining under-screened and under-treated. Factors contributing to this include the asymptomatic early stages of the disease, lack of awareness, economic barriers, and inconsistent screening practices, especially in under-resourced areas. These challenges are compounded by disparities that affect different genders and races unevenly, influencing both the prevalence of the disease and the likelihood of receiving adequate healthcare services. The summary of this chapter underscores the urgent need for targeted strategies to overcome these barriers and improve health equity in osteoporosis care. Proposed strategies include enhancing public and healthcare provider awareness of osteoporosis, broadening access to diagnostic screenings, and integrating personalized treatment approaches. These efforts aim to align with global health objectives to mitigate the impacts of osteoporosis and ensure equitable health outcomes across all demographic groups.
