ADVANCING ROTATOR CUFF HEALING AT THE ENTHESIS

ROTIUM® is an interpositional wick placed at the tendon-bone interface designed to supercharge the biologic environment for support of the healing cascade and improvement in long-term outcomes after rotator cuff repair.

The biologic healing challenge

Retear rates remain high—averaging over 35% across published studies
The focus has been on mechanical fixation, overlooking the biologic gap at the enthesis
Healing often occurs through scar tissue formation, compromising long-term durability

The rotium advantage

ROTIUM targets the biologic gap at the enthesis—delivering the patient’s own healing factors where they’re needed most. Its placement between tendon and bone promotes scarless healing, strong integration, and restoration of a functional repair.

efficiency meets biology

Rotium scaffold implant

Designed for efficiency, ROTIUM integrates seamlessly into standard rotator cuff repair techniques without adding surgical time.

The bioresorbable scaffold delivers targeted biologic support directly at the repair site to enhance the healing environment and promote native tissue regeneration.

Clinical Success & Proven Science

Backed by 16 years of research, Atreon’s technology delivers science-driven solutions that support healing, enhance repair, and elevate surgical outcomes.

Patient Outcomes Study Findings: Patients who received the ROTIUM scaffold had a significantly lower cumulative treatment failure rate (7.1%) compared to those who did not receive the scaffold (50%) over an average follow-up of 17 months.

Animal Study Findings: Results showed that ROTIUM scaffold-augmented repairs exhibited increased failure strength and bone-tendon integration with the development of Sharpey-like fibers at the tendon-bone interface, suggesting improved healing.
