Generating the American Shoulder and Elbow Surgeons Score Using Multivariable Predictive Models and Computer Adaptive Testing to Reduce Survey Burden.

Background: The preferred patient-reported outcome measure for the assessment of shoulder conditions continues to evolve. Previous studies correlating the Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive tests (CATs) to the American Shoulder and Elbow Surgeons (ASES) score have focused on a singular domain (pain or physical function) but have not evaluated the combined domains of pain and physical function that compose the ASES score. Additionally, previous studies have not provided a multivariable prediction tool to convert PROMIS scores to more familiar legacy scores.

Epidemiology of Posterior Glenohumeral Instability in a Young Athletic Population.

Background: While several studies have observed the incidence of posterior glenohumeral instability in selected populations, there are no data from large-scale population-based studies with corresponding athletic exposure data to calculate incidence rates (IRs) and associated risk factors.

Purpose: To determine risk factors for posterior glenohumeral instability within the physically active population at the United States Military Academy.

Study Design: Descriptive epidemiology study.

Anteromedializing Tibial Tubercle Osteotomy for Patellofemoral Instability: Occupational and Functional Outcomes in U.S. Military Service Members.

This article sought to determine rates for return to work, pain relief, and recurrent patellofemoral instability for military service members undergoing tibial tubercle osteotomy (TTO) for persistent lateral patellar subluxation or dislocation. Patient demographic and surgical variables were isolated from the medical records of active duty service members with at least 2 years of postoperative follow-up, and correlated with return to work, pain improvement, recurrent patellofemoral instability, and perioperative complications. There were 51 service members (58 primary TTOs) with an average follow-up of 3.

Variables Affecting Return to Play After Anterior Cruciate Ligament Injury in the National Football League.

Background: Anterior cruciate ligament (ACL) injuries are common in the National Football League (NFL). Limited literature exists regarding return to play (RTP) and the factors affecting RTP after ACL reconstruction in NFL players.

Purpose/hypothesis: To determine RTP rates after ACL reconstruction in NFL players and to ascertain which variables affect RTP in these players.

The Success of Hip Arthroscopy in an Active Duty Population.

Purpose: To examine the outcomes of arthroscopic treatment of the hip in a young, active military population. Specifically, the ability to return to duty was the prime indicator of success. In addition, an objective evaluation of various demographic and surgery-related variables was performed to identify predictors for success or failure of treatment in this military population.

Medialized Clavicular Bone Tunnel Position Predicts Failure After Anatomic Coracoclavicular Ligament Reconstruction in Young, Active Male Patients.

Background: Recent radiographic data have suggested that medialized conoid tunnel placement greater than 25% of absolute clavicular length is correlated with early failure after anatomic coracoclavicular ligament reconstructions. A comparison with a larger active duty military cohort of clinical and radiographic outcomes can serve as a basis for standardizing surgical technique.

Purpose: To establish the ideal radiographic tunnel position for anatomic coracoclavicular ligament reconstruction and to elucidate variables associated with early loss of reduction and ability to return to active-duty military service.

Comparison of the Suture Anchor and Transosseous Techniques for Patellar Tendon Repair: A Biomechanical Study.

Background: Minimizing gap formation and maximizing the strength of patellar tendon repairs are 2 critical factors for successful healing of these injuries.

Purpose/hypothesis: The purpose of this study was to compare transosseous and screw-in anchor repair techniques to determine if there is a difference in gap formation and load to failure of the 2 constructs. The research hypotheses were that the anchor construct would have significantly less gap formation and would also have significantly greater load-to-failure strength.

The Effect of Syndesmosis Screw Removal on the Reduction of the Distal Tibiofibular Joint: A Prospective Radiographic Study.

Background: Injury to the tibiofibular syndesmosis is frequent with rotational ankle injuries. Multiple studies have shown a high rate of syndesmotic malreduction with the placement of syndesmotic screws. There are no studies evaluating the reduction or malreduction of the syndesmosis after syndesmotic screw removal.

Radial collateral ligament injuries of the thumb metacarpophalangeal joint: epidemiology in a military population.

Purpose: The reasons for variation in the reported incidence rates between thumb metacarpophalangeal joint radial collateral ligament (RCL) and ulnar collateral ligament (UCL) injuries are unclear. Delay in diagnosis of injury to the RCL leads to greater time of patient disability. The purpose of this study was to define the demographics and presentation of patients with RCL injuries in a military health care system.
