Randomized Controlled Trial Comparative Study
Comparison Between Single- and Double-Bundle Anterior Cruciate Ligament Reconstruction With 6- to 8-Stranded Hamstring Autograft: A Prospective, Randomized Clinical Trial.
Whether double-bundle (DB) anterior cruciate ligament (ACL) reconstruction with 6- to 8-stranded hamstring autograft (HG) is better than single-bundle (SB) ACL reconstruction remains debatable, as long-term follow-up data are lacking. ⋯ Both SB and DB ACL reconstruction with 6- to 8-stranded HG showed satisfactory results in subjective scores and anteroposterior and rotational stability over a nearly 7-year follow-up; neither technique was superior.

Randomized Controlled Trial
A Randomized Controlled Trial With Mean 16-Year Follow-up Comparing Hamstring and Patellar Tendon Autografts in Anterior Cruciate Ligament Reconstruction.
There is no consensus in the current literature on which surgical options render the best long-term results after anterior cruciate ligament (ACL) reconstruction in terms of clinical outcomes and the development of radiographic osteoarthritis (OA). ⋯ Only minor and mostly insignificant differences were found between the PT and HT autograft groups in this long-term randomized controlled trial. In both groups, significantly more signs of radiographic OA were found in the reconstructed knee than in the contralateral knee.

The Sport Concussion Assessment Tool-3 (SCAT3) facilitates sideline clinical assessments of concussed athletes. Yet, there is little published research on clinically relevant metrics for the SCAT3 as a whole. ⋯ Individual predictors should be taken into account when interpreting the SCAT3. The normative conversion tables and RCIs presented can be used to help interpret concussed athletes' performance both with and without baseline data, given the comparability of the 2 interpretative approaches.

Comparative Study
Outcomes of Anatomic Anterior Cruciate Ligament Reconstruction: Bone-Quadriceps Tendon Graft Versus Double-Bundle Hamstring Tendon Graft.
The choice of graft type is an important factor to the outcome of anterior cruciate ligament (ACL) reconstruction. ⋯ Anatomic ACL reconstruction with the BQT autograft showed similar knee stability and functional outcome scores when compared with the DBHT autograft. Additionally, better flexor muscle strength recovery was found in the quadriceps group, indicating a potential advantage of the BQT autograft in ACL reconstruction.

Concussions are common in football, and knowledge of their incidence rates across settings is needed to develop strategies to decrease occurrence. ⋯ Study results show that (1) based on activity type, games and preseason training camp present the greatest risk of sustaining a concussion; (2) based on play type, special teams plays pose the greatest risk of sustaining a concussion; and (3) the 2010 NCAA concussion management policy coincided with a significant increase in recognition of concussion.
