Determinants of Return to Play After the Nonoperative Management of Hamstring Injuries in Athletes: A Systematic Review
Conclusion: Numerous determinants have an effect on return to play after a hamstring injury in athletes. It is important for sports professionals to be aware of those determinants to guide athletes through the rehabilitation process and refine return-to-play strategies.

Product Differences in Intra-articular Hyaluronic Acids for Osteoarthritis of the Knee
Conclusion: Despite similarities, IA-HA products should not be treated as a group, as there are differences in IA-HA products that influence both efficacy and safety. In the available literature, IA-HA products with a molecular weight ≥3000 kDa and those derived from biological fermentation relate to superior efficacy and safety—factors that may influence selection an IA-HA product for OA of the knee.

Influence of Playing a Prolonged Tennis Match on Shoulder Internal Range of Motion
Conclusion: Passive shoulder internal rotation and total ROM are significantly decreased during a 3-hour tennis match. Clinical Relevance: The results show that a prolonged tennis match play can modify values of shoulder ROM. (Source: The American Journal of Sports Medicine)

Does Pure Platelet-Rich Plasma Affect Postoperative Clinical Outcomes After Arthroscopic Rotator Cuff Repair?: A Randomized Controlled Trial
Conclusion: Patients treated with pure PRP showed no significantly improved function at 3, 6, and 24 months after arthroscopic repair compared with control patients receiving ropivacaine; however, a similar pain reduction was documented in both groups. The negative influence of smoking on the effect of pure PRP requires further investigation. Registration: NCT01266226 (ClinicalTrials.gov). (Source: The American Journal of Sports Medicine)

Fastball Pitch Velocity Helps Predict Ulnar Collateral Ligament Reconstruction in Major League Baseball Pitchers
Conclusion: Higher pitch velocity is the most predictive factor of UCLR in MLB pitchers, with higher weight and younger age being secondary predictors, although these factors only explained 7% of the variance in UCLR rates. (Source: The American Journal of Sports Medicine)

Femoral Neck Stress Fracture: Can MRI Grade Help Predict Return-to-Running Time?
Conclusion: Grade 2 to 4 femoral neck stress fractures require longer RTR time than do grade 1 injuries. Patients with lower BMI tend to require a longer RTR time. (Source: The American Journal of Sports Medicine)

Hamstring Reinjuries Occur at the Same Location and Early After Return to Sport: A Descriptive Study of MRI-Confirmed Reinjuries
Conclusion: The majority of the hamstring reinjuries occurred in the same location as the index injury, early after RTS and with a radiologically greater extent, suggesting incomplete biological and/or functional healing of the index injury. Specific exercise programs focusing on reinjury prevention initiated after RTS from the index injury are highly recommended. (Source: The American Journal of Sports Medicine)

Femoroacetabular Impingement in Adolescent Athletes: Outcomes of Arthroscopic Management
Conclusion: This study reports favorable outcomes of arthroscopic treatment of FAI among adolescent athletes. A high proportion improved, although only 87% actually returned to their sport. Return to sport may be influenced by factors other than just the success of the procedures. (Source: The American Journal of Sports Medicine)

The ACL Graft Has Different Cross-sectional Dimensions Compared With the Native ACL: Implications for Graft Impingement
Conclusion: Native ACLs have a smaller cross-sectional area, are "flatter," and experience less incidence of impingement compared with anatomically placed BPTB ACL grafts. (Source: The American Journal of Sports Medicine)

Strain Response of the Anterior Cruciate Ligament to Uniplanar and Multiplanar Loads During Simulated Landings: Implications for Injury Mechanism
Conclusion: In the presence of impulsive axial compression, the combination of anterior tibial shear force, knee abduction, and internal tibial rotation moments significantly increases ACL strain, which could result in ACL failure. These findings support multiplanar knee valgus collapse as one the primary mechanisms of noncontact ACL injuries during landing. Clinical Relevance: Intervention programs that address multiple planes of loading may decrease the risk of ACL injury and the devastating consequences of posttraumatic knee osteoarthritis.

Comparison of the Suture Anchor and Transosseous Techniques for Patellar Tendon Repair: A Biomechanical Study
Conclusion: The results support the 2 study hypotheses. These findings suggest that the 4.75-mm PEEK screw-in anchor construct may be superior to the transosseous technique for minimizing gap formation and improving load-to-failure strength after surgical repair of the patellar tendon. Clinical Relevance: The use of the suture anchor technique in patellar tendon repair may support early load-bearing rehabilitation. (Source: The American Journal of Sports Medicine)
