Five articles from the May 2015 issue summarized in five minutes, with the addition of a brief editorial commentary. The 5-in-5 feature is designed to give readers an overview of articles that may pique their interest and encourage more detailed reading. It may also be used by busy readers who would prefer a brief audio summary in order to select the articles they want to read in full. The featured articles for this month are “Association of Equipment Worn and Concussion Injury Rates in National Collegiate Athletic Association Football Practices: 2004-2005 to 2008-2009 Academic Years,” “Prevalence of and Risk Factors for Dislocation Arthropathy Radiological Long-term Outcome of Arthroscopic Bankart Repair in 100 Shoulders at an Average 13-Year Follow-up,” “No Association Between Fibrosis on Magnetic Resonance Imaging at Return to Play and Hamstring Reinjury Risk,” “Relationship Between Knee Mechanics and Time Since Injury in ACL-Deficient Knees Without Signs of Osteoarthritis,” and “Tibial and Femoral Tunnel Changes After ACL Reconstruction: A Prospective 2-Year Longitudinal MRI Study."

Distal biceps brachii tendon repairs performed with a tension slide technique using a cortical button (CB) and interference screw are stronger than those based on suture fixation through bone tunnels (BTs) in biomechanical studies. However, clinical comparison of these 2 techniques is lacking in the literature. Both the single-incision CB and double-incision BT techniques provided excellent clinical results. Complications were more common in the single-incision CB group and most commonly involved paresthesias of the superficial radial nerve.

The tibial tubercle–trochlear groove (TT-TG) distance and trochlear structure have become important radiographic measurements in the evaluation and management of patients with patellar instability. Many orthopaedic surgeons, however, do not have access to musculoskeletal radiologists and therefore must make such measurements independently. The results of this study suggest that the intra- and interobserver reliability in the MRI measurement of the TT-TG distance and TDI is high for both orthopaedic surgeons and musculoskeletal radiologists. In addition, the TT-TG distance may be lower than previously thought in patients with patellar instability.

Five articles from the April 2015 issue summarized in five minutes, with the addition of a brief editorial commentary. The 5-in-5 feature is designed to give readers an overview of articles that may pique their interest and encourage more detailed reading. It may also be used by busy readers who would prefer a brief audio summary in order to select the articles they want to read in full. The featured articles for this month are “Sports-Specialized Intensive Training and the Risk of Injury in Young Athletes: A Clinical Case-Control Study,” “The Prevalence and Combined Prevalences of Anatomic Factors Associated With Recurrent Patellar Dislocation: A Magnetic Resonance Imaging Study,” “Association Between Ball-Handling Versus Defending Actions and Acute Noncontact Lower Extremity Injuries in High School Basketball and Soccer,” “Does Obesity Affect Outcomes in Hip Arthroscopy?: A Matched-Pair Controlled Study With Minimum 2-Year Follow-up,” and “On-Site Treatment of Exertional Heat Stroke.”

Recent prospective randomized trials support primary plate fixation of displaced midshaft clavicle fractures. However, the safety and efficacy of this practice have not been well documented in athletes, nor has the time to return-to-sport. The Latarjet procedure can provide satisfactory outcomes, including a low recurrence rate and reliable functional recovery. Defects at the anteroinferior glenoid were restored to nearly normal after coracoid transfer by use of the Latarjet procedure, which is an anatomically matched reconstruction.

Five articles from the March 2015 issue summarized in five minutes, with the addition of a brief editorial commentary. The 5-in-5 feature is designed to give readers an overview of articles that may pique their interest and encourage more detailed reading. It may also be used by busy readers who would prefer a brief audio summary in order to select the articles they want to read in full. The featured articles for this month are “MRI Volume and Signal Intensity of ACL Graft Predict Clinical, Functional, and Patient-Oriented Outcome Measures After ACL Reconstruction,” “Surgical Management of Osteochondritis Dissecans Lesions of the Patella and Trochlea in the Pediatric and Adolescent Population,” “Structural Properties of the Intact Proximal Hamstring Origin and Evaluation of Varying Avulsion Repair Techniques: An In Vitro Biomechanical Analysis,” “Anterior Cruciate Ligament Reconstruction With Contralateral Autogenous Patellar Tendon Graft: Evaluation of Donor Site Strength and Subjective Results,” and “Revision Versus Primary Arthroscopic Rotator Cuff Repair: A 2-Year Analysis of Outcomes in 360 Patients."

Five articles from the February 2015 issue summarized in five minutes, with the addition of a brief editorial commentary. The 5-in-5 feature is designed to give readers an overview of articles that may pique their interest and encourage more detailed reading. It may also be used by busy readers who would prefer a brief audio summary in order to select the articles they want to read in full. The featured articles for this month are "The Impact of Previous Hamstring Strain Injury on the Change in Eccentric Hamstring Strength During Pre-Season Training in Elite Australian Footballers," "The Effect of Donor Age on the Structural and Mechanical Properties of Allograft Tendons," Femoral Nerve Blockade is Associated with Persistent Strength Deficits at Six Months Post ACL Reconstuction in Pediatric and Adolescent Patients," "Factors Affecting Capsular Volume Changes and Association with Outcomes after Bankart Repair and Capsular Shift," and "Correlation of Meniscal and Articular Cartilage Injuries in Children and Adolescents with Timing of ACL Reconstruction."

Rotator cuff tears are common, and rotator cuff repair represents a major health care expense. While patients often benefit from rotator cuff repair, anatomic failure of the repair is not unusual. In spite of a dramatic increase in the number of publications per year, there is little evidence that the results of rotator cuff repair are improving. The information needed to guide the management of this commonly treated and costly condition is seriously deficient. To accumulate the evidence necessary to inform practice, future clinical studies on the outcome of rotator cuff repair must report important data relating to each patient’s condition, the surgical technique, the outcome in terms of integrity, and the change in patient self-assessed comfort and function.

There has been an increase in minimally invasive surgery for chronic exertional compartment syndrome (CECS), despite the potential for incomplete compartment release and iatrogenic injuries. To our knowledge, no study has examined the effect of the length of fascial release on compartment pressures. This study demonstrates a strong correlation between fasciotomy length and a reduction in intracompartmental pressures in a swine model. Our study suggests that 90% fascial release may represent a possible watershed zone, returning the intracompartmental pressure to a value at or near baseline values.
