The company developed the complete instrumentation system specifically for subscapularis-sparing total shoulder arthroplasty (TSA). It aims to enable surgeons to replace a damaged shoulder joint while keeping the shoulder muscle intact.

According to J&J MedTech — one of the largest medtech companies in the world — more than 100,000 people in the U.S. undergo TSA each year. It treats degenerative conditions like osteoarthritis and rotator cuff tears. While effective, the company says the traditional deltopectoral approach often requires the detachment of the subscapularis tendon. As a result, patients often face up to six weeks of post-operative immobilization, the company said.
