Five articles from the September 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 “Factors Associated With Failure of Nonoperative Treatment in Lateral Epicondylitis,” “Select Injury-Related Variables Are Affected by Stride Length and Foot Strike Style During Running,” “The Effect of Diabetes, Hyperlipidemia, and Statins on the Development of Rotator Cuff Disease: A Nationwide, 11-Year, Longitudinal, Population-Based Follow-up Study,” “Relationship Between Quadriceps Strength and Patellofemoral Joint Chondral Lesions After Anterior Cruciate Ligament Reconstruction,” and “Effects of Acetabular Rim Trimming on Hip Joint Contact Pressures: How Much Is Too Much?”

Excessive physiological anterior and rotational knee laxity is thought to be a risk factor for noncontact anterior cruciate ligament (ACL) injuries and inferior reconstruction outcomes, but no thresholds have been established to identify patients with increased laxity. The healthy contralateral knees of patients with noncontact ACL injuries display different laxity values both for internal rotation and anterior displacement compared with healthy control knees. The identification of knee laxity profiles may be of relevance for primary and secondary prevention programs of noncontact ACL injuries.

Recent publications have described significant variability in the femoral attachment and overall anatomy of the anterolateral ligament (ALL). Additionally, there is a paucity of data describing its structural properties. Defined ALL attachment locations can be reproducibly identified with intraoperative landmarks or radiographs. The biomechanical analysis suggests that most traditional soft tissue grafts are sufficient for ALL reconstruction.

While the preparticipation evaluation (PPE) is widely used by medical practitioners, its overall effectiveness is unknown, in part because there are no standardized or centralized mechanisms to collect and analyze medical historyinformation. While some data in this population are self-evident, we were not aware of the high frequency of past injuries, the magnitude of time lost from sport, the high frequency of past surgery, and the number of participants still symptomatic from injuries. The ePPE is a valuable tool for collecting and analyzing aggregate injury and illness data in athletes, such as the finding that 11% of injuries that were reported were unresolved and still symptomatic.

The featured articles for this month are "The Effect of Trochlear Dysplasia on Patellofemoral Biomechanics: A Cadaveric Study With Simulated Trochlear Deformities," "A Comparative Study on the Biomechanical and Histological Properties of Bone-to-Bone, Bone-to-Tendon, and Tendon-to-Tendon Healing: An Achilles Tendon–Calcaneus Model in Goats," "The Effect of a Combined Glenoid and Hill-Sachs Defect on Glenohumeral Stability: A Biomechanical Cadaveric Study Using 3-Dimensional Modeling of 142 Patients," "Platelet-Rich Plasma Increases Anti-inflammatory Markers in a Human Coculture Model for Osteoarthritis," and "Shoulder Functional Performance Status of National Collegiate Athletic Association Swimmers: Baseline Kerlan-Jobe Orthopedic Clinic Scores."

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.
