The study aimed to compare the constraint levels of reverse total shoulder arthroplasty (rTSA) liners from different implant systems, focusing on how design affects stability.
Using 3D planning software, measurements of jump height, stability ratio, and angle of coverage were conducted for various liner sizes to evaluate differences among implant systems.
Results indicated significant variability in stability ratios and jump heights between different rTSA systems, with some systems maintaining consistency in stability across sizes while others showed considerable inconsistencies.
