Previous studies have determined the percentage of studies presented at national orthopaedic surgery meetings that are eventually published in peer-reviewed journals. ⋯ A high proportion of studies accepted for publication in AJSM are presented at national and international meetings. AOSSM and AAOS Annual Meetings are the most common conferences at which these studies are presented, although international conferences account for a substantial proportion of AJSM-published study presentations.

A hamstring strain injury (HSI) has become the most common noncontact injury in soccer. Isokinetic muscle strength deficits are considered a risk factor for HSIs. However, underpowered studies with small sample sizes unable to determine small associations have led to inconclusive results regarding the role of isokinetic strength and strength testing in HSIs. ⋯ This study identified small absolute strength differences and a wide overlap of the absolute strength measurements at the group level. The small associations between lower hamstring eccentric strength and lower quadriceps concentric strength with HSIs can only be considered as weak risk factors. The identification of these risk factors still does not allow the identification of individual players at risk. The use of isokinetic testing to determine the association between strength differences and HSIs is not supported.

There are limited studies on the effect of mild osteoarthritis (OA) on outcomes of hip arthroscopic surgery. ⋯ At 2-year follow-up, patients with Tönnis grade 1 OA had improved outcomes after hip arthroscopic surgery, with no significant difference compared with a matched control group of patients with Tönnis grade 0 OA. However, further studies are underway to determine if the results of the Tönnis grade 1 cohort will deteriorate over longer term follow-up.

Tibial slope angle is a nonmodifiable risk factor for anterior cruciate ligament (ACL) injury. However, the mechanical role of varying tibial slopes during athletic tasks has yet to be clinically quantified. ⋯ The knee torques that positively correlated with increased tibial slope angle in this investigation are associated with heightened risk of ACL injury. Therefore, the present data indicated that a higher posterior tibial slope is correlated to increased knee loads that are associated with heightened risk of ACL injury.
