Global Rating Scales and Motion Analysis Are Valid Proficiency Metrics in Virtual and Benchtop Knee Arthroscopy Simulators

Justues Chang MD, Daniel C. Banaszek MD, Jason Gambrel MD, Davide Bardana MD

Work-hour restrictions and fatigue management strategies in surgical training programs continue to evolve in an effort to improve the learning environment and promote safer patient care. In response, training programs must reevaluate how various teaching modalities such as simulation can augment the development of surgical competence in trainees. For surgical simulators to be most useful, it is important to determine whether surgical proficiency can be reliably differentiated using them. To our knowledge, performance on both virtual and benchtop arthroscopy simulators has not been concurrently assessed in the same subjects.

What Risk Factors Are Associated With Musculoskeletal Injury in US Army Rangers? A Prospective Prognostic Study

Deydre S. Teyhen PT, PhD, Scott W. Shaffer PT, PhD, Robert J. Butler PT, PhD, Stephen L. Goffar PT, PhD, Kyle B. Kiesel PT, PhD, Daniel I. Rhon PT, DSc, Jared N. Williamson DPT, Phillip J. Plisky PT, DSc

Musculoskeletal injury is the most common reason that soldiers are medically not ready to deploy. Understanding intrinsic risk factors that may place an elite soldier at risk of musculoskeletal injury may be beneficial in preventing musculoskeletal injury and maintaining operational military readiness. Findings from this population may also be useful as hypothesis-generating work for particular civilian settings such as law enforcement officers (SWAT teams), firefighters (smoke jumpers), or others in physically demanding professions.

Left Knee Pain and Bilateral Knee Swelling in an Adolescent

Diagnosing Periprosthetic Joint Infection: Has the Era of the Biomarker Arrived?

Carl Deirmengian MD, Keith Kardos PhD, Patrick Kilmartin, Alexander Cameron, Kevin Schiller, Javad Parvizi MD

The diagnosis of periprosthetic joint infection (PJI) remains a serious clinical challenge. There is a pressing need for improved diagnostic testing methods; biomarkers offer one potentially promising approach.

Is Peroneal Nerve Injury Associated With Worse Function After Knee Dislocation?

Aaron J. Krych MD, Steven A. Giuseffi MD, Scott A. Kuzma MD, Michael J. Stuart MD, Bruce A. Levy MD

Peroneal nerve palsy is a frequent and potentially disabling complication of multiligament knee dislocation, but little information exists on the degree to which patients recover motor or sensory function after this injury, and whether having this nerve injury–with or without complete recovery–is a predictor of inferior patient-reported outcome scores.

Labral Injuries of the Hip in Rowers

Robert E. Boykin MD, Eric D. McFeely BA, Kathryn E. Ackerman MD, MPH, Yi-Meng Yen MD, PhD, Adam Nasreddine MA, Mininder S. Kocher MD, MPH

Injuries of the hip in the adolescent and young adult athlete are receiving more attention with advances in the understanding of femoroacetabular impingement (FAI), labral pathology, and hip arthroscopy. Labral tears have not been well characterized in rowers.

Efficacy and Degree of Bias in Knee Injury Prevention Studies: A Systematic Review of RCTs

Nathan L. Grimm BS, Kevin G. Shea MD, Ryan W. Leaver DPT, Stephen K. Aoki MD, James L. Carey MD, MPH

Knee injury prevention programs have been developed to address the epidemic of knee injuries in young athletes. These programs include exercises that focus on balance, proprioception, and neuromuscular control. Some studies have suggested such specialized exercise programs may reduce the risk of knee injury.

Does Landmark Selection Affect the Reliability of Tibial Tubercle–Trochlear Groove Measurements Using MRI?

Jason J. Wilcox MD, Brian J. Snow MD, Stephen K. Aoki MD, Man Hung PhD, Robert T. Burks MD

A lateralized tibial tubercle is one potential cause of patellar instability. The tibial tubercle–trochlear groove (TT-TG) distance using CT is a reliable measure and considered the gold standard. Using MRI for this purpose has increased, although the reliability of doing so is not well studied.

‘Batter’s Shoulder’: Can Athletes Return to Play at the Same Level After Operative Treatment?

Tony Wanich MD, Joshua Dines MD, David Dines MD, Ralph A. Gambardella MD, Lewis A. Yocum MD

Batter’s shoulder has been defined as posterior subluxation of the lead shoulder during the baseball swing. However, it is unclear whether or how frequently patients may return to play after treatment of this uncommon condition.

Glenoid Stress Distribution in Baseball Players Using Computed Tomography Osteoabsorptiometry: A Pilot Study

Tomohiro Shimizu MD, Norimasa Iwasaki MD, PhD, Kinya Nishida MD, PhD, Akio Minami MD, PhD, Tadanao Funakoshi MD, PhD

It is important to understand the loading conditions when considering the pathology of shoulder disorders in overhead athletes. However, because throwing is a complicated motion and methods to directly determine stress distribution are complex, direct measurement of the stress distribution across the glenohumeral joint has not been attempted. Subchondral bone density reportedly reflects the cumulative stress acting on a joint surface under actual loading conditions.
