rise in the pediatric and adolescent patient populations,
with incidence rates peaking at age 16 years
for female patients and at age 17 years for male patients.
A Biomechanical Assessment of Biceps Femoris Repair Techniques
With the lack of pitch count regulation, youth softball pitchers
are experiencing unremitting high stresses on the anterior
shoulder. The purpose of this study was to examine the association
of acute changes in the long head of the biceps tendon
with pitching kinematics and kinetics in youth softball pitchers
following an acute bout of pitching.
Distal Insertions of the Biceps Femoris: A Quantitative Analysis
Avulsion of the biceps femoris from the fibula and proximal tibia is encountered in clinical practice. While the anatomy of the primary posterolateral corner structures has been qualitatively and quantitatively described, a quantitative analysis regarding the insertions of the biceps femoris on the fibula and proximal tibia is lacking.
Knee Reconstruction: High Flexion Total Knee Arthroplasty
As population shifts occur in age and demographics, our goals for
restoration of function have grown in knee arthroplasty.With this
focus has come the advent of high-flexion components whose
designs have sought to advance the recreation of normal knee
kinematics.
Anchor Repair of Biceps Femoris Repair Is Similar to Knotless Tunnel Repair in Laboratory Conditions
The review included 19 studies involving a total of 811 participants. Platelet-rich plasma (PRP) was found
to significantly reduce pain, as measured by the VAS scores, and to improve functional outcomes including the
modified Harris Hip Score (mHHS) and the Western Ontario and McMaster Universities Osteoarthritis Index
(WOMAC) scores. These findings suggest that PRP may be an effective treatment for GTPS. The studies reported
minimal side effects that were generally mild and transient.
Biomechanical Comparison of Arthroscopic Repair Constructs for Radial Tears of the Meniscus
As biologic augmentation methods emerge, objective measures of soft tissues are necessary for developmental
study. The purpose of this study was to develop a quantitative MRI mapping protocol for the ACL.
Biomechanical Comparison of Parallel and Crossed Suture Repair for Longitudinal Meniscus Tears
Longitudinal meniscus tears are commonly encountered in clinical practice. Meniscus repair devices have been previously tested and presented; however, prior studies have not evaluated repair construct designs head to head. This study compared a new-generation meniscus repair device, SpeedCinch, with a similar established device, Fast-Fix 360, and a parallel repair construct to a crossed construct.
Biological Enhancement of Meniscus Repair and Replacement
When a meniscus injury occurs, it is generally accepted that preserving the meniscus is important for life-long joint preservation. Traditional suture repair of the meniscus has good results; however, the healing potential of meniscus tissue remains as a biological challenge because it is not a completely vascularized structure.

Association of Maximum Pitch Velocity and Elbow Injury in Professional Baseball Pitchers
Recent literature has explored the association of upper extremity injury in baseball players with various aspects of the pitching motion. To our knowledge, no study has directly evaluated the connection between maximum pitch velocity and elbow injury in professional baseball pitchers.
Correlation of Torque and Elbow Injury in Professional Baseball Pitchers
During the pitching motion, velocity is generated by the upper extremity kinetic chain on internal rotation of the shoulder and trunk translational/rotational motion. This generation of power places significant forces and torques on the elbow and shoulder. Elbow valgus torque and shoulder rotational torque are theoretically linked to elbow injury.
Editorial Commentary: Elbow Injury Results When Pediatric and Adolescent Throwing Athletes Throw as Hard as Possible, and Weighted Baseball Training Should Be Banned for Youth Athletes
We are in the middle of an epidemic involving pediatric and adolescent throwing athletes. Too many young athletes have elbow injuries, and it is unnerving how young surgical indications can present. Increased competition has led to increased demands before athletes have reached their full adult size.
