Increasing incidence of concussion and head injury due to electric biking: a 10-year sex- and age-specific analysis of national injury data.

Objectives: Electric biking (e-biking) is a rapidly growing recreation, sport, and mode of transportation that often presents to emergency departments (EDs) with high-impact head injuries. This study aimed to evaluate the epidemiology of e-bike-related concussions and closed-head injuries (CHI) to inform more effective injury prevention strategies.

Methods: The National Electronic Injury Surveillance (NEISS) was queried for e-bike related concussions and CHIs presented to national EDs from 1 January 2013-31 December 2022.

Osteoporosis Management for Shoulder Surgeons.

Purpose Of Review: The aim of this review is to aggregate currently available literature as it pertains to treating surgical shoulder pathology in patients with osteoporosis.

Recent Findings: Emerging data surrounding perioperative use of anti-osteoporosis medications for patients undergoing shoulder surgery have not shown definitively favorable or unfavorable outcomes. Similar evaluations in animal studies have shown promising results as a biologic augment to tendon and bone healing, especially with newer, anabolic agents.

Management of Shoulder Instability in the Overhead Athletes.

Overhead athletes with anterior, posterior, and multidirectional shoulder instability present with a wide range of symptoms, especially considering the injury mechanism and affected supportive structures. As such, the management of shoulder instability is widely variable and relies on rehabilitation, operative management, and sport-specific considerations, such as positional and seasonal demands on the athlete. Biomechanical analysis may further aid in the recovery process or serve as a predictive tool to identify an increased risk for injury.

Partial-Thickness Rotator Cuff Tears: Current Concepts.

» Partial-thickness rotator cuff tears (PTRCTs) are a common pathology with a likely high asymptomatic incidence rate, particularly in the overhead athlete.» The anatomy, 5-layer histology, and relationship to Ellman's classification of PTRCTs have been well studied, with recent interest in radiographic predictors such as the critical shoulder angle and acromial index.» Depending on the definition of tear progression, rates of PTRCT progression range from 4% to 44% and appear related to symptomatology and work/activity level.

The Impact of Drive Leg Impulse and Slope on Throwing Velocity and Kinematics in the Competitive Throwing Athlete.

Background: Multiple studies have analyzed pitching kinematics using motion analysis technology, but lower extremity drive leg impulse (DLI) and drive leg slope (DLS) are not as well characterized. The purpose of this study was to investigate associations between DLI and DLS and pitch velocity as well as angular velocity of the pelvis, trunk, and humerus.

Hypothesis: Increased DLI and DLS will be correlated positively with pitch velocity and associated with increased angular velocities in the humerus, trunk, and pelvis.

Previous Knee Surgery, Anteromedial Portal Drilling, Quadriceps Tendon Autograft, and Meniscal Involvement Associated With Delayed Return to Sport After Anterior Cruciate Ligament Reconstruction in Amateur Athletes.

Purpose: To identify prognostic factors associated with a delayed return-to-sport (RTS) time in amateur athletes who return to full participation after a primary isolated anterior cruciate ligament (ACL) reconstruction.

Methods: A retrospective review was performed among athletes who underwent ACL reconstruction between October 2014 and October 2021. Inclusion criteria were any amateur athletes with an ACL reconstruction who had a documented RTS and greater than 1-year follow-up.

Editorial Commentary: The Shoulder Instability-Return to Sports After Injury Scale Is More Than Just a Psychological Readiness Tool-It Is a Potential Predictive Model for Outcomes and Recurrence.

The Shoulder Instability-Return to Sports After Injury (SIRSI) scale is a useful psychological readiness tool to determine whether athletes are prepared to return to sport. Although questions remain on the optimal timing of survey administration based on the type of procedure (i.e.

Rates and predictors of reimplantation of matrix-induced autologous chondrocyte implantation following first stage cartilage harvest: A cohort study.

Purpose: To assess the reimplantation rate and predictors of patients requiring second-staged matrix-induced autologous chondrocyte implantation (MACI) reimplantation after initial first stage cartilage biopsy.

Methods: A retrospective review was performed from 2018 to 2022 among patients who underwent only phase I MACI biopsy procedure (biopsy group) or both phase I with transition to phase II implantation of chondrocytes (implantation group) at a single tertiary center. Demographic, qualitative, and quantitative measurements were recorded, and univariate and multivariate regression analysis was performed to assess predictors of ultimately requiring second stage MACI implantation.

Posterior Shoulder Instability, Part II-Glenoid Bone Grafting, Glenoid Osteotomy, and Rehabilitation/Return to Play-An International Expert Delphi Consensus Statement.

Purpose: To establish consensus statements on glenoid bone grafting, glenoid osteotomy, rehabilitation, return to play, and follow-up for posterior shoulder instability.

Methods: A consensus process on the treatment of posterior shoulder instability was conducted, with 71 shoulder/sports surgeons from 12 countries participating on the basis of their level of expertise in the field. Experts were assigned to 1 of 6 working groups defined by specific subtopics within posterior shoulder instability.

Arthroscopic suture bridge fixation for acute bony Bankart with anterior glenohumeral instability: a case report and narrative review.

Background And Objective: Anterior shoulder dislocations can result in acute glenoid rim fractures that compromise the bony stability of the glenohumeral joint. Adequate fixation of these fractures is required to restore stability, decrease shoulder pain, and facilitate return to activity. The double-row suture bridge is a relatively novel fixation technique, first described in 2009, that accomplishes internal fixation with sufficient stability using an all-arthroscopic technique to restore the glenoid footprint.

Knotless Re-tensionable Direct Fixation of Medial Meniscus Posterior Root Tears.

Over the past decade, there has been an increased awareness of the recognition and treatment of medial meniscus posterior root tears. Recent systematic reviews and meta-analyses have shown that surgical repair of medial meniscus posterior root tears is effective in improving patient-reported outcome measures and decreasing the progression of osteoarthritis when compared with nonoperative treatment or meniscectomy. The available techniques currently consist of transosseous suture fixation and direct suture anchor fixation, with transosseous repairs being the most frequently performed.

Management of Bone Loss in Posterior Glenohumeral Shoulder Instability: Current Concepts.

» Posterior glenohumeral instability is relatively uncommon compared with anterior instability, but is becoming an increasingly recognized and surgically managed shoulder pathology.» Soft-tissue stabilization alone may not be sufficient in patients who present with substantial bone loss to the posterior glenoid and/or the anterior humeral head.» For posterior glenoid defects, posterior glenoid osteoarticular augmentation can be used, and posterior glenoid opening wedge osteotomy can be considered in cases of posterior instability with pathologic retroversion.

Bioactive and Bioinductive Implants Are Increasingly Used in Orthopaedic Sports Medicine but Adequately Controlled Studies Are Needed: A Scoping Review.

Purpose: To describe the currently available literature reporting clinical outcomes for bioactive and bioinductive implants in sports medicine.

Methods: In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic search of 4 databases was completed to identify eligible studies. Inclusion criteria were studies using bioactive or bioinductive implants in human clinical studies for sports medicine procedures.

Batter's Shoulder: All-Knotless Posterior Labral Repair With Retensionable Anchors for Treatment of Batter's Shoulder.

Batter's Shoulder is a unique injury that may be associated with recurrent microtrauma followed by acute subluxation of the humeral head on the posterior glenoid edge, leading to posterior labral tears. Early identification of this injury is critical, as it may be treated with conservative nonsurgical treatments prior to labral tear onset. If conservative treatment fails and pain persists, surgical options include arthroscopic fixation to reapproximate the posterior labrum to the glenoid and restore capsular tension.

Osteochondral Allograft Transplantation in the Knee.

Osteochondral injuries of the knee can be a frequent source of debilitating pain and dysfunction. Significant chondral (>1.5-2 cm) lesions of the femoral condyles can be especially difficult to manage with nonsurgical measures.

Adding Lateral Retinacular Release to Medial Patellofemoral Ligament Reconstruction Fails to Demonstrate Clinical Benefit Compared With Isolated Medial Patellofemoral Ligament Reconstruction.

Purpose: To compare functional outcomes and failure rates between medial patellofemoral ligament (MPFL) reconstructions with and without lateral retinacular release (LRR) at minimum 1-year follow up.

Methods: A retrospective review identified consecutive patients from 2013 to 2019 at a single center who met all of the following inclusion criteria: at least 1 confirmed patellar dislocation, patellar tilt (evidenced by tight retinaculum on operative examination or patellar tilt on radiographs), underwent either MPFL reconstruction alone or combined with LRR, had available preoperative documentation and imaging, and were at least 1 year out of surgery. Patients were excluded if they had previous surgery to the ipsilateral limb or had any concomitant procedure performed.

Editorial Commentary: Suture-Button Fixation May Have Advantages Over Screw Fixation for Glenoid Bone Grafting Procedures for Shoulder Instability.

Orthopaedic suture buttons have been increasingly used in a variety of procedures, such as syndesmosis stabilization, coracoclavicular ligament repair, anterior cruciate ligament graft fixation, and Lisfranc injury treatment. In many instances, suture-button fixation constructs have shown equivalent, if not superior, outcomes to screw fixation. More recently, suture buttons have been suggested for osseous fixation of the coracoid during the Latarjet procedure, as well as other anterior (or posterior) bone block reconstruction of the glenoid using distal tibial allograft, tricortical iliac crest, or distal clavicle in cases of complex shoulder instability.

Early Anterior Cruciate Ligament Treatment Might Be Crucial for Acute Combined Anterior Cruciate Ligament and Medial Collateral Ligament Injuries: A Systematic Review of the Various Treatment Strategies.

Purpose: To assess the outcomes of acute, combined, complete anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries in the literature.

Methods: A literature search using PubMed, Embase, Scopus, and Cochrane Reviews was performed following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. The inclusion criteria were studies reporting outcomes of complete ACL-MCL injuries at a minimum of 12 months' follow-up.

Editorial Commentary: Meniscal Allograft Transplantation Is Effective for Adolescents With Meniscal Insufficiency, Although Outcomes May Decline Over Time.

Over the last several years, there has been a shift from arthroscopic partial meniscectomy to meniscal repair, especially in the younger patient. In case of a necessary partial meniscectomy, some patients have unremittent symptoms of pain and effusion corresponding to the postmeniscectomy syndrome. In these patients without large coronal malalignment, meniscal allograft transplantation is a valuable option to restore contact pressures, promote a chondroprotective microenvironment, and potentially delay secondary surgical interventions symptoms.

Editorial Commentary: Lower Trapezius Transfer May Be Indicated for Surgical Management of Massive Irreparable Rotator Cuff Tears in Younger, Non-Arthritic Patients.

Although shoulder rotator cuff repair fixation constructs and suture anchor design have evolved, repair of massive or functionally irreparable tears historically has relied on tendon mobilization and compression, optimizing footprint biology, and attempting a tension-free repair. However, despite these efforts, rates of failure of complete healing may be high, ranging from 20% to 94%. This has led to a search for alternative approaches, including bridging grafts, subacromial balloons, superior capsular reconstructions, biologic tuberoplasties, bursal acromial grafts, and, ultimately, renewed interest in tendon transfers.

Editorial Commentary: At Least 2 out of 3 Adolescent Athletes Can Return to Preinjury Sports After Marrow Stimulation for Osteochondritis Dissecans of the Elbow.

Osteochondritis dissecans (OCD) of the capitellum is a common cause of elbow pain in young throwers and gymnasts, symptoms of which can rob these young athletes of valuable time participating in sporting activities. The optimal treatment of adolescent capitellar OCD lesions is dependent on a variety of patient- and lesion-specific factors, including, but not limited to, lesion size, lesion location, physeal status, and lesion chronicity. Promisingly, marrow stimulation with or without debridement appears to confer high return-to-sport rates coupled with a low complication rate for young athletes suffering from this condition.
