Catalyst OrthoScience

Catalyst OrthoScience is a commercial-stage orthopedic device company specializing in next-generation shoulder replacement systems. Founded in 2015 and based in Naples, Florida, the company differentiates itself through its science-driven, bone-preserving implant designs, including its stemless, elliptical humeral head and simplified reverse shoulder system. With a focus on clinical validation and enabling efficiency in ASCs, Catalyst aims to address key challenges in shoulder arthroplasty by offering solutions that promote anatomic restoration and faster patient recovery.

A shoulder arthroplasty platform centered on an elliptical (non-spherical) humeral head design, stemless/canal-sparing fixation via a multiplanar osteotomy, and a simplified single-tray reverse system, all aimed at anatomic restoration and bone preservation.

Catalyst competes in the crowded shoulder arthroplasty market dominated by multinational giants like Stryker, Zimmer Biomet, Johnson & Johnson (DePuy Synthes), and Smith & Nephew. Its primary competitive differentiation is its focus on elliptical head anatomy and stemless fixation, competing against other niche players with stemless offerings (e.g., Arthrex's Univers Revers, Exactech's Equinoxe Stemless) and the broader market of traditional stemmed spherical implants.
