Lateral versus medial offset design for reverse shoulder replacement

Reverse total shoulder arthroplasty (RTSA) has become significantly more popular in recent years due to expanding indications and successful long-term outcomes being reported. RTSA has undergone several iterations throughout history that has led to modern-day designs. What initially started as a salvage procedure for cuff-deficient shoulders is now commonly used for a variety of reconstructive shoulder problems not limited just to those without a functioning rotator cuff. The goal of this article was to compare and contrast lateral and medial offset designs for RTSA. Details of both glenoid and humeral-sided design characteristics are discussed as well as existing biomechanical and clinical literature for both designs.
