Reliability and Validity of the Sport Concussion Assessment Tool-3 (SCAT3) in High School and Collegiate Athletes
Conclusion: 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.

Epidemiology of Sport-Related Concussion in an NCAA Division I Football Bowl Subdivision Sample
Conclusion: 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.

Concussion Incidence and Return-to-Play Time in National Basketball Association Players: Results From 2006 to 2014
Conclusion: Although the incidence of publicly reported concussions in the NBA has not changed appreciably over the past 9 seasons, the time missed after a concussion has. While players often returned in the same game in the 2006 season, the combination of implemented policy, national coverage, medical staff awareness, and player education may have contributed to players now missing an average of 4 to 6 games after a concussion. A multitude of factors has resulted in more conservative return-to-play practices for NBA players after concussions. (Source: The American Journal of Sports Medicine)

The NFL Orthopaedic Surgery Outcomes Database (NO-SOD): The Effect of Common Orthopaedic Procedures on Football Careers
Conclusion: ACLR, Achilles tendon repair, and patellar tendon repair have the greatest effect on NFL careers, with patellar tendon repair faring worst with respect to the RTP rate, career length after surgery, games played, and performance at 1 year and 2 to 3 years after surgery.

The Effect of a High Pitch Volume on Musculoskeletal Adaptations in High School Baseball Pitchers
Conclusion: Dominant versus nondominant ROM differences did not progress during the season, or from one year to the next, and were unaffected by pitch volume. A high pitch volume was associated with in-season supraspinatus weakness and diminished strength gains from one year to the next. In conclusion, a high pitch volume appeared to have a catabolic effect on supraspinatus strength. (Source: The American Journal of Sports Medicine)

Ibuprofen Differentially Affects Supraspinatus Muscle and Tendon Adaptations to Exercise in a Rat Model
Conclusion: Chronic administration of ibuprofen does not impair supraspinatus tendon mechanical properties in a rat model of exercise but does decrease supraspinatus muscle fiber cross-sectional area. This fundamental study adds to the growing literature on the effects of ibuprofen on musculoskeletal tissues and provides a solid foundation on which future work can build. Clinical Relevance: The study findings suggest that ibuprofen does not detrimentally affect regulation of supraspinatus tendon adaptations to exercise but does decrease muscle growth. Individuals should be advised on the risk of decreased muscle hypertrop...

Efficacy of a Subacromial Corticosteroid Injection for Persistent Pain After Arthroscopic Rotator Cuff Repair
Conclusion: A subacromial corticosteroid injection can be considered as a useful and safe modality for the treatment of patients having severe persistent pain during the recovery phase after arthroscopic rotator cuff repair. (Source: The American Journal of Sports Medicine)

The Medial Stitch in Transosseous-Equivalent Rotator Cuff Repair: Vertical or Horizontal Mattress?
Conclusion: In transosseous-equivalent rotator cuff repairs near the musculotendinous junction, a vertical mattress suture used as the medial stitch has a higher load to failure but no difference in gapping compared with a horizontal mattress pattern. Clinical Relevance: A vertical mattress suture may offer enhanced strength of repair for transosseous-equivalent repairs. (Source: The American Journal of Sports Medicine)

Relationship Between Humeral Retroversion and Length of Baseball Career Before the Age of 16 Years
Conclusion: These results suggest that humeral retroversion increases with decreasing age at commencement of a baseball career before age 16 years in pitchers. (Source: The American Journal of Sports Medicine)

Humeral Torsion as a Risk Factor for Shoulder and Elbow Injury in Professional Baseball Pitchers
Conclusion: The results of this study show a contrast in dominant humeral retrotorsion between pitchers who suffered shoulder and elbow injuries compared with those without an injury. Pitchers who sustained shoulder injuries had less dominant humeral retrotorsion compared with noninjured pitchers. In contrast, pitchers who sustained time-loss elbow injuries displayed increased humeral retrotorsion compared with noninjured pitchers. Together, these results suggest that increased adaptive humeral retrotorsion is protective against shoulder injuries but a harmful contributor for elbow injuries in professional pitchers. This i...

Should We Limit Innings Pitched After Ulnar Collateral Ligament Reconstruction in Major League Baseball Pitchers?
Conclusion: The number of innings pitched and number of pitches thrown in the first full season as well as over a player’s career after UCLR are not associated with an increased risk of a pitcher requiring revision UCLR. (Source: The American Journal of Sports Medicine)

Predictors of Ulnar Collateral Ligament Reconstruction in Major League Baseball Pitchers
Conclusion: This study identified 6 key performance factors that may present significant risk factors for UCL reconstruction in MLB pitchers. These findings could help to enhance the prevention of UCL reconstruction surgery in MLB pitchers and shape the direction of future research in this domain.
