Treatment and Early Outcomes of Capitellar Osteochondritis Dissecans.

Background: Treatment for osteochondritis dissecans (OCD) of the humeral capitellum has been predominantly guided by fragment stability and articular cartilage integrity. Nonoperative management is recommended for stable lesions, whereas surgical intervention is indicated for unstable lesions and those that fail nonoperative care. Several surgical options may be considered, although limited information is available regarding indications for specific surgical techniques and comparative postoperative results.

Tarsal Navicular Bone Stress Injuries: A Multicenter Case Series Investigating Clinical Presentation, Diagnostic Approach, Treatment, and Return to Sport in Adolescent Athletes.

Background: Tarsal navicular bone stress injuries (BSIs) are considered "high risk" because of prolonged healing times and higher rates of nonunion in adult populations but, to our knowledge, have not been comprehensively examined in adolescent athletes.

Purpose: To describe the characteristics of tarsal navicular BSIs in adolescents.

Study Design: Case series; Level of evidence, 4.

Resolution of Sleep Disturbance and Improved Functional Outcomes After Rotator Cuff Repair.

Background: Most patients experience sleep disturbances before rotator cuff repair, with these symptoms largely improving postoperatively. However, the relationship between the resolution or persistence of sleep disturbance and patient-reported outcomes after rotator cuff repair remains unknown.

Purpose: To compare outcomes after rotator cuff repair between patients who reported a preoperative sleep disturbance and those who did not.

Descriptive Epidemiology of a Surgical Patellofemoral Instability Population of 492 Patients.

Background: Patellofemoral instability (PFI) occurs most commonly in pediatric and adolescent patients, with evolving indications for surgery and changes in surgical techniques over the past decade.

Purpose: To characterize the demographic, clinical, and radiologic characteristics of a large cohort of patients undergoing PFI surgery and investigate longitudinal trends in techniques utilized over a 10-year period at a tertiary-care academic center.

Study Design: Case series; Level of evidence, 4.

Surgical Treatment of Solitary Periarticular Osteochondromas About the Knee in Pediatric and Adolescent Patients: Complications and Functional Outcomes.

Background: Solitary osteochondromas, or osteocartilaginous exostoses (OCEs), represent the most common benign bone tumor. Despite frequently causing symptoms about the knee in younger populations, there is minimal previous literature investigating surgical treatment.

Methods: We retrospectively reviewed the records of patients <20 years old who had undergone surgical treatment of symptomatic, pathologically confirmed, solitary periarticular knee OCE at a single pediatric center between 2003 and 2016.

Do Resident Surgical Volumes and Level of Training Correlate with Improved Performance on Psychomotor Skills Tasks: Construct Validity Testing of an ASSH Training Platform (STEP)?

Unlabelled: The Surgical Training and Educational Platform (STEP) was developed by the American Society for Surgery of the Hand (ASSH) as a cost-effective set of surgical simulation modules designed to assess critical skills in hand surgery. Previous study demonstrated that STEP can differentiate between novice trainees and board-certified, certificate of added qualification hand surgeons. The purpose of this study was to assess construct validity of STEP by testing its ability to differentiate psychomotor skill level among intermediate trainees.

Early Outcomes of Adolescent ACL Reconstruction With Hybrid Hamstring Tendon Autograft-Allograft Versus Hamstring Tendon Autograft Alone.

Background: Small-diameter semitendinosus-gracilis tendon autografts may be encountered intraoperatively during anterior cruciate ligament reconstruction (ACLR); these have been shown to be at increased risk of graft rupture. One option that surgeons have pursued to reduce the theoretical failure rate of these smaller-diameter grafts is augmenting them with allograft material, thereby forming a larger-diameter hybrid autograft-allograft construct.

Purpose/hypothesis: The purpose of this study was to compare outcomes in adolescent athletes of primary ACLR using a hybrid autologous hamstring tendon and soft tissue allograft construct versus ACLR using small-diameter hamstring tendon autograft.

Evaluation and Surgical Management of Knee Osteochondritis Dissecans and Adolescent Cartilage Injuries.

Osteochondritis dissecans and cartilage injuries of the knee are among the most challenging clinical entities that pediatric sports medicine specialists encounter. As a weight-bearing joint with significant long-term implications on mobility and overall physical health, the knee also happens to be the most injured or adversely affected joint in preadolescent and adolescent athletes. However, cartilage injuries are unique among other musculoskeletal pathologies in children, in that the healing potential of articular cartilage tissue is limited, and minor injuries or small focal defects can have devastating implications on the lifelong health of the joint.

Surgical Reconstruction of Missed Monteggia Lesions in Children.

Background: Chronic Monteggia lesions in children may cause pain, deformity, decreased range of motion, and neurological symptoms. Numerous surgical techniques have been advocated to reconstruct long-standing Monteggia injures in efforts to maximize long-term upper limb function. The purpose of this investigation was to assess the clinical and radiographic results of a modified surgical technique for missed Monteggia fracture-dislocations.

The Frequency of Mediastinal Injury in Acute Posterior Sternoclavicular Dislocations: A Multicenter Study.

Background: Acute posterior sternoclavicular dislocations (APSCD) are rare injuries that historically have prompted concern for injury to the great vessels and other mediastinal structures from initial trauma or subsequent treatment, resulting in the recommendation that a thoracic or vascular surgeon be present or available during operative treatment. The objectives of the study were to characterize the demographic, clinical, and radiographic characteristics of a large series of APSCDs in skeletally immature patients and to describe the rate and nature of any vascular or mediastinal complications that occurred during treatment.

Methods: Following Institutional Review Board approval, records of consecutive patients under 25 years of age treated for APSCD were collected from each of 6 participating centers.
