Tips for Successful Ulnar Collateral Ligament Reconstruction
UCL reconstruction has become one of the defining operations in throwing sports, and the elbow it repairs rarely fails all at once. This surgical technique article walks through a hamstring autograft reconstruction and the outcomes throwers can realistically expect.
Outcomes of ream and run shoulder arthroplasty with a stemless humeral component
The first reported clinical outcomes for ream-and-run shoulder arthroplasty performed with a stemless humeral component.

Relationship Between Arm Path, Ball Velocity, and Elbow Varus Torque in Professional Baseball Pitchers
Pitching coaches almost universally teach a shorter arm path, on the theory that it protects the elbow and adds velocity. Motion capture on 182 professional pitchers found the two do not come together: shortening the arm path lowers elbow torque and lowers velocity with it.
Moderate Return to Play and Previous Performance After SLAP Repairs in Competitive Overhead Athletes: A Systematic Review
Returning to play after SLAP repair and returning to previous form are two different outcomes. A review of 333 competitive overhead athletes separates them.
An evidence-based approach to managing unexpected positive cultures in shoulder arthroplasty
Positive cultures often appear in shoulder replacement patients with no sign of infection. A review of 22 studies asks what they mean and whether treatment should change.
Does native glenoid anatomy predispose to shoulder instability? An MRI analysis
It is unclear if native glenohumeral anatomic features predispose young patients to instability and if such anatomic risk factors differ between males and females…
Trends in outpatient versus inpatient total shoulder arthroplasty over time
More shoulder replacements are now same-day procedures. A study of over 25,000 patients tracks how outpatient and inpatient complication rates have shifted across 14 years.
