The Effect of Mild-to-Moderate Preoperative Patellar Tendinopathy in Autografts Used for Anterior Cruciate Ligament Reconstruction on Postoperative Outcomes.

Introduction: The purpose of this study was to investigate whether patellar tendinopathy on preoperative MRI in patients undergoing anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone (BTB) autograft has an effect on retears, subsequent surgeries, and postoperative patient-reported outcomes (PROs).

Methods: Patients who underwent primary or revision ACL reconstruction with BTB autograft with preoperative MRI and minimum 2 years of follow-up were included. Concomitant procedures, demographic data, retears, and subsequent surgeries were documented.

The role of hinged external fixation in the treatment of knee dislocation, subluxation and fracture-dislocation: A systematic review of indications.

Purpose: While rigid knee-spanning external fixation is more commonly utilized in the treatment of complex knee injuries compared to hinged external fixation (HEF), HEF has the added benefit of providing stability while also permitting early controlled range of motion. However, there is limited existing literature on the indications for HEF of the knee. The aim of this study was to review the clinical indications for HEF in the management of acute and chronic knee dislocations (KD), tibiofemoral subluxations and knee fracture-dislocations.

Surgical Excision of a Cyclops Lesion After ACL Reconstruction in an Elite College Athlete.

Background: Cyclops lesion after anterior cruciate ligament (ACL) reconstruction can appear on magnetic resonance imaging (MRI) in up to 30% of patients and is symptomatic in up to 9%. Arthroscopic cyclops removal can help restore motion and limit recurrence.

Indications: Patient is an 18-year-old male high-level collegiate athlete with a mechanical block to full extension.

Editorial Commentary: Tension of the Repair During Rotator Cuff Surgery Appears to Matter More Than Medial-Lateral Footprint Coverage.

The ideal rotator cuff repair construct has low tension, maximizes footprint coverage, is biomechanically strong, and optimizes tendon-to-bone healing. However, these principles are not always feasible, especially with larger tear patterns and poor tendon quality, factors that are also associated with higher retear rates. There is a constant effort with often opposing priorities to achieve a tension-free rotator cuff repair while also achieving maximal footprint coverage.

Management of Isolated Partial ACL Tears: A Survey of International ACL Surgeons.

Background: Partial anterior cruciate ligament (ACL) tears, particularly injuries detected with magnetic resonance imaging (MRI) but stable on ligamentous examination, appear to be recognized more frequently; however, there remains no consensus management for this complex pathology.

Purpose: To present the results of a survey of a group of international ACL experts on the management of partial ACL injuries.

Study Design: Survey study; Level of evidence, 5.

No Difference in Chondrocyte Viability Using Manual Versus Custom-Cutting Technique for Matrix-Induced Autologous Chondrocyte Implantation.

Background: Matrix-induced autologous chondrocyte implantation (MACI) was developed for knee cartilage restoration involving seeding autologous chondrocytes onto a collagen membrane. Maintaining chondrocyte viability and achieving proper membrane size and contour are crucial for successful outcomes. Scissor cutting (Sc) has traditionally been used to shape the membrane, but recently, custom cutting (CC) have gained popularity for their enhanced preparation efficiency.

Background: Acromioclavicular (AC) joint injuries pose significant challenges in clinical management, necessitating consensus guidelines for optimal treatment. There is a lack of consensus in several areas, including imaging protocols, surgical techniques, and rehabilitation timelines. This study aims to develop a consensus regarding the diagnosis, treatment, and rehabilitation of AC joint separations.

Health Numeracy Is Associated With a Patient's Ability to Interpret Patient-Reported Outcome Measures Data.

Background: Patient-reported outcome measures (PROMs) were originally developed as research tools; however, there is increasing interest in using PROMs to inform clinical care. Prior work has shown the benefits of implementing PROMs at the point of care, but a patient's health numeracy (their ability to understand and work with numbers) may affect their ability to interpret PROM results.

Materials And Methods: We recruited patients presenting to an outpatient orthopedic clinic.

Glenoid structural bone grafting in reverse total shoulder arthroplasty: clinical and radiographic outcomes.

Background: Current options for reconstruction of large glenoid defects in reverse total shoulder arthroplasty (RTSA) include structural bone grafting, use of augmented components, or 3D-printed custom implants. Given the paucity in the literature on structural bone grafts in RTSA, this study reflects our experience on clinical and radiographic outcomes of structural bone grafts used for glenoid defects in RTSA.

Methods: We identified 33 consecutive patients who underwent RTSA using structural bone grafts for glenoid bone loss between 2008 and 2019.

Editorial Commentary: Acromioclavicular Joint Reconstruction With Double-Bundle Constructs Provides Improved Maintenance of Reduction but Comparable Clinical Outcomes Versus Single-Bundle Constructs.

Treatment of acute acromioclavicular (AC) joint separations is dependent on a variety of factors, including severity, acuity, patient demographics, activity level, and surgeon preferences. For more severe or unstable separations (Rockwood types IIIB, IV, V, and VI), surgical intervention is typically recommended. Over 160 surgical techniques have been described, but none have emerged as a gold standard.

High accuracy of intra-articular needle position during anterior landmark guided glenohumeral injections.

Objectives: Image-guided ultrasound or fluoroscopic glenohumeral injections have high accuracy rates but require training, equipment, cost, and radiation exposure (fluoroscopy). In contrast, landmark-guided glenohumeral injections do not require additional subspecialist referrals or equipment. An optimal technique would be safe and accurate and have few barriers to implementation.

Assessment of a Synergistic Effect of Platelet-Rich Plasma and Stem Cell-Seeded Hydrogel for Healing of Rat Chronic Rotator Cuff Injuries.

Outcomes after repair of chronic rotator cuff injuries remain suboptimal. Type-1 collagen-rich tendon hydrogel was previously reported to improve healing in a rat chronic rotator cuff injury model. Stem cell seeding of the tendon hydrogel improved bone quality in the same model.

Knee MRI: Meniscus Roots, Ramps, Repairs, and Repercussions.

Menisci play an essential role in maintaining normal pain-free function of the knee. While there are decades of MRI literature on the tears involving the meniscus body and horns, there is now a surge in knowledge regarding injuries at the meniscus roots and periphery. The authors briefly highlight new insights into meniscus anatomy and then summarize recent developments in the understanding of meniscus injuries that matter, emphasizing meniscus injuries at the root and peripheral (eg, ramp) regions that may be missed easily at MRI and arthroscopy.

No significant difference in risk of prolonged opioid use following outpatient versus inpatient total shoulder arthroplasty: A propensity matched analysis.

Background: The purpose of this investigation was to compare rates of filled opioid prescriptions and prolonged opioid use in opioid naïve patients undergoing total shoulder arthroplasty (TSA) in inpatient versus outpatient settings.

Methods: A retrospective cohort study was conducted using a national insurance claims database. Inpatient and outpatient cohorts were created by identifying continuously enrolled, opioid naïve TSA patients.

The Use of Biologics in NFL Athletes: An Expert Consensus of NFL Team Physicians.

Purpose: To develop a consensus on the use of biologics among NFL team physicians.

Study Design: Consensus statement.

Biomechanical, Histologic, and Micro-Computed Tomography Characterization of Partial-Width Full-Thickness Supraspinatus Tendon Injury in Rats.

Purpose: Partial rotator cuff tears can cause shoulder pain and dysfunction and are more common than complete tears. However, few studies examine partial injuries in small animals and, therefore a robust, clinically relevant model may be lacking. This study aimed to fully characterize the established rat model of partial rotator cuff injury over time and determine if it models human partial rotator cuff tears.

Prevalence of Positive Rapid Antigen Tests After 7-Day Isolation Following SARS-CoV-2 Infection in College Athletes During Omicron Variant Predominance.

Importance: The US Centers for Disease Control and Prevention shortened the recommended isolation period for SARS-CoV-2 infection from 10 days to 5 days in December 2021. It is unknown whether an individual with the infection may still have a positive result to a rapid antigen test and potentially be contagious at the end of this shortened isolation period.

Objective: To estimate the proportion of individuals with SARS-CoV-2 infection whose rapid antigen test is still positive starting 7 days postdiagnosis.

A Genome-Wide Association Study Reveals Two Genetic Markers for Chondromalacia.

Objective: It is unknown why some athletes develop chondromalacia and others do not, even when accounting for similar workloads between individuals. Genetic differences between individuals may be a contributing factor. The purpose of this work was to screen the entire genome for genetic markers associated with chondromalacia.

Increased Risk of ACL Injury for Female but Not Male Soccer Players on Artificial Turf Versus Natural Grass: A Systematic Review and Meta-Analysis.

Background: Both natural grass (NG) and artificial turf (AT) are popular playing surfaces for soccer. Biomechanical studies have found increased frictional forces on AT that may lead to anterior cruciate ligament (ACL) injury. The increased risk of ACL injury during soccer in female participants may amplify this effect.

Patients Who Return to Sport After Primary Anterior Cruciate Ligament Reconstruction Have Significantly Higher Psychological Readiness: A Systematic Review and Meta-analysis of 3744 Patients.

Background: Although objective outcomes assessing knee function are essential measurements for return to sport, psychological factors have become increasingly recognized as equally important parameters for determining an athlete's ability to return to sport after surgery.

Purpose: To systematically review the literature to determine whether patients who returned to sport after anterior cruciate ligament (ACL) reconstruction had improved psychological scores (as measured with validated questionnaires) compared with patients who did not return to sport.

Study Design: Systematic review and meta-analysis; Level of evidence, 3.

This case series evaluates the performance of rapid antigen tests in detecting SARS-CoV-2 infection in college athletes during prevalence of a dominant Omicron variant.

Ulnar Collateral Ligament Reconstruction Does Not Decrease Spin Rate or Performance in Major League Pitchers.

Background: Ulnar collateral ligament reconstruction (UCLR) is commonly performed in Major League Baseball (MLB) pitchers, with variable reported effects on velocity and traditional rate statistics. Currently, no studies have evaluated spin rate in the context of return to play (RTP) after injury. Greater spin rate has become increasingly sought after in the baseball community, as it is believed to be a vital aspect of pitch effectiveness.

Editorial Commentary: Soaking Anterior Cruciate Ligament Grafts in Vancomycin Solution Lowers Infection Rates Without Lowering Functional Outcomes.

Soaking anterior cruciate ligament grafts in vancomycin solution is done by many surgeons. Research has indicated decreased infection rates and similar anterior cruciate ligament retear rates between grafts soaked in vancomycin solution before implantation versus those without. In addition, there has been basic science evidence for tenocyte survival and viability even when exposed to vancomycin solution.
