Neither Residual Anterior Knee Laxity Up to 6 mm nor a Pivot Glide Predict Patient-Reported Outcome Scores or Subsequent Knee Surgery Between 2 and 6 Years After ACL Reconstruction.

Background: A primary goal of anterior cruciate ligament reconstruction (ACLR) is to reduce pathologically increased anterior and rotational laxity of the knee, but the effects of residual laxity on patient-reported outcomes (PROs) after ACLR remain unclear.

Hypothesis: Increased residual laxity at 2 years postoperatively is predictive of a higher risk of subsequent ipsilateral knee surgery and decreases in PRO scores from 2 to 6 years after surgery.

Study Design: Cohort study; Level of evidence, 2.

Medical Diagnoses in a University Athlete Training Room Clinic.

Introduction: Approximately 560 000 student-athletes participate in university athletic programs every year. These athletes develop a variety of medical injuries and illnesses during their time at the university. There is currently a paucity of data with regarding medical encounters in a dedicated university athlete training room clinic.

Overuse Elbow Injuries in Youth Gymnasts.

Background: Gymnastics is a unique sport that places significant loads across the growing elbow, resulting in unique overuse injuries, some of which are poorly described in the current literature.

Purpose: To provide a comprehensive review of the unique overuse elbow injuries seen in youth gymnasts and to provide an up-to-date synthesis of the available literature and clinical expertise guiding treatment decisions in this population.

Study Design: Narrative review.

Return to Play After Revision Anterior Shoulder Stabilization: A Systematic Review.

Background: Revision shoulder stabilizations are becoming increasingly common. Returning to play after revision shoulder stabilizations is important to patients.

Purpose: To evaluate the return-to-play rate after revision anterior shoulder stabilization using arthroscopic, open, coracoid transfer, or free bone block procedures.

Proximal Hamstring Injuries.

Proximal hamstring injuries can present as chronic tendinosis, acute strain, partial tendinous avulsions, or complete 3-tendon rupture. Nonoperative management for chronic insertional tendinosis and low-grade tears includes activity modification, anti-inflammatories, and physical therapy. Platelet-rich plasma injections, corticosteroid injections, dry needling, and shock wave therapy are newer therapies that also may provide benefit.

Development of Concise Physical Performance Test Batteries in Young Athletes.

Purpose: This study aimed 1) to define the principal components of physical function assessed by 10 common lower extremity physical performance tests and 2) to derive a reduced-item set of physical performance tests that efficiently and accurately measures raw performance and limb symmetry on each underlying component in pediatric and adolescent athletes.

Methods: This study included healthy, uninjured volunteers (n = 100) between the ages 6 and 18 yr (mean age = 11.7 ± 3.

Scapular Stabilization Limits Glenohumeral Stretching in Children With Brachial Plexus Injuries.

Purpose: To quantify the effects of scapular stabilization on scapulothoracic and glenohumeral (GH) stretching.

Methods: Motion capture data during external rotation and abduction with and without scapular stabilization were collected and analyzed for 26 children with brachial plexus birth palsy. These positions were performed by an experienced occupational therapist and by the child's caretaker.

Adjustable-Loop Femoral Cortical Suspensory Fixation for Patellar Tendon Anterior Cruciate Ligament Reconstruction: A Time Zero Biomechanical Comparison With Interference Screw Fixation.

Background: Adjustable-loop cortical buttons for femoral fixation of bone-tendon-bone grafts have potential advantages over interference screw fixation; however, these devices have not been benchmarked biomechanically against interference screws. Purpose/Hypothesis: The purpose was to compare the time zero biomechanical properties of commercially available, adjustable-loop cortical button and metallic interference screws for femoral fixation of bone-tendon-bone grafts. It was hypothesized that no significant differences would be found in biomechanical properties between fixation techniques.

Foot and Ankle Surgery: Common Problems and Solutions.

Participation in sports activity has increased significantly during the last several decades. This phenomenon has exposed orthopedic sports medicine surgeons to new challenges regarding the diagnosis and management of common sport-related injuries. Arthroscopy is becoming more commonly used in many of the surgical procedures for these injuries and carries the risk of complications.

Understanding Preferences for Treatment After Hypothetical First-Time Anterior Shoulder Dislocation: Surveying an Online Panel Utilizing a Novel Shared Decision-Making Tool.

Background: Although surgical management of a first-time anterior shoulder dislocation (FTASD) can reduce the risk of recurrent dislocation, other treatment characteristics, costs, and outcomes are important to patients considering treatment options. While patient preferences, such as those elicited by conjoint analysis, have been shown to be important in medical decision-making, the magnitudes or effects of patient preferences in treating an FTASD are unknown.

Purpose: To test a novel shared decision-making tool after sustained FTASD.

Autologous Chondrocyte Implantation Improves Knee-Specific Functional Outcomes and Health-Related Quality of Life in Adolescent Patients.

Background: Existing studies of autologous chondrocyte implantation (ACI) in adolescent patients have primarily reported outcomes that have not been validated for cartilage repair and have failed to include measures of general health or health-related quality of life.

Purpose: This study assesses validated knee-specific functional outcomes and health-related quality of life after ACI in adolescent patients.

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

Hip Dislocation or Subluxation After Hip Arthroscopy: A Systematic Review.

Purpose: To determine patient- and surgery-specific characteristics of patients sustaining postarthroscopic hip dislocation or subluxation.

Methods: A systematic review of multiple medical databases was registered with PROSPERO and performed using Preferred Reporting Items for Systemic Reviews and Meta-Analysis guidelines. Level I to IV clinical outcome studies reporting the presence of hip dislocation or subluxation after hip arthroscopy were eligible.

Inside-Out Antegrade Tibial Tunnel Drilling Through the Posterolateral Portal Using a Flexible Reamer in Posterior Cruciate Ligament Reconstruction.

Posterior cruciate ligament (PCL) reconstruction using the transtibial drilling or arthroscopic tibial-inlay technique has a risk of injury to the popliteal neurovascular bundle because a pin is drilled anterior to posterior. Intraoperative fluoroscopy is used to decrease the risk of neurovascular injury. In addition, graft passage in the transtibial technique may be problematic because of a sharp turn when placing the graft into the tibial tunnel, which may damage graft fibers.
