Recent advances and future innovations in shoulder arthroplasty: a review of the current literature

There have been incredible innovations in knowledge, techniques, and implants for total shoulder arthroplasty over the last few decades. On the humeral side, modularity has improved the ability to recreate native anatomy, while shorter humeral stems have improved our ability to preserve bone stock. On the glenoid side, the anatomic restoration and baseplate fixation have improved and augments have allowed surgeons to overcome bone loss. Future innovations in implant design, surgical technique and planning will continue to improve this operation. These will likely include robotic assisted surgery, augmented reality, patient specific guides, and others. In this review, the recent literature highlighting important recent innovations in the field of shoulder arthroplasty are critically reviewed and compiled. Recent innovations and projected future trends are discussed.
