Platelet-Rich Plasma Activates Proinflammatory Signaling Pathways and Induces Oxidative Stress in Tendon Fibroblasts
Conclusion: PRP induces an inflammatory response in tendon fibroblasts, which leads to the formation of ROS and the activation of oxidative stress pathways. PRP does not appear to significantly modulate macrophage polarization. Clinical Relevance: PRP might act by inducing a transient inflammatory event, which could then trigger a tissue regeneration response. (Source: The American Journal of Sports Medicine)

Cartilage Restoration of the Knee: A Systematic Review and Meta-analysis of Level 1 Studies
Conclusion: There is no significant difference between MS, ACI, and OAT in improving function and pain at intermediate-term follow-up. Further randomized trials with long-term outcomes are warranted. (Source: The American Journal of Sports Medicine)

Return to Sport After Rotator Cuff Tear Repair: A Systematic Review and Meta-analysis
Conclusion: Most recreational athletes return to sports at the same level of play as before their injury, but only half of professional and competitive athletes return to an equivalent level of play. (Source: The American Journal of Sports Medicine)

Risk of Secondary Injury in Younger Athletes After Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis
Conclusion: This systematic review and meta-analysis demonstrates that younger age and a return to high level of activity are salient factors associated with secondary ACL injury. These combined data indicate that nearly 1 in 4 young athletic patients who sustain an ACL injury and return to high-risk sport will go on to sustain another ACL injury at some point in their career, and they will likely sustain it early in the return-to-play period. The high rate of secondary injury in young athletes who return to sport after ACLR equates to a 30 to 40 times greater risk of an ACL injury compared with uninjured adolescents. Thes...

Trends in Authorship Characteristics in The American Journal of Sports Medicine, 1994 to 2014
Conclusion: Within the past 2 decades, there has been a significant increase in the average number of authors per article in AJSM, as well as a higher proportion of international groups and academic institutions publishing in the journal. More nonphysicians are publishing in AJSM, with a significantly higher percentage of first authors with a bachelor’s degree as their highest degree. This is likely due to a combination of a general increased interest in research as well as increased competition among medical students. These factors have likely led to larger research groups and thus a significantly higher average num...

Conference Presentation Characteristics of Studies Published in The American Journal of Sports Medicine
Conclusion: 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.

Are Pulley Exercises Initiated 6 Weeks After Rotator Cuff Repair a Safe and Effective Rehabilitative Treatment?: A Randomized Controlled Trial
Conclusion: A rotator cuff repair rehabilitation program that uses pulleys does not result in inferior outcomes, as determined by patient-determined outcome scores, measurements of scapular substitution, range of motion, and scaption strength.

Incidence Rate and Results of the Surgical Treatment of Pectoralis Major Tendon Ruptures in Active-Duty Military Personnel
Conclusion: Among military personnel, Army soldiers and junior officer/enlisted rank were at highest risk of pectoralis major tendon ruptures, and junior personnel were at highest risk of being unable to return to duty after surgical treatment. Although increasing time from injury to surgery was not a risk factor for treatment failure or inability to return to duty, it did significantly increase the risk of a postoperative complication.
