Catalyst OrthoScience Announces 5-8 Year Data Reporting Significant Functional Improvement and Pain Reduction for Anatomic Total Shoulder Arthroplasty

Catalyst OrthoScience Inc. (“Catalyst”), a private medical technology leader focused on shoulder arthroplasty, the fastest growing segment in the orthopedics market, today announced positive, mid-term data reporting on patients treated with its Catalyst CSR™ shoulder system was published in the Journal of Shoulder and Elbow Surgery. This is the ninth peer-reviewed publication for the Catalyst CSR system, which has previously shown to more accurately restore the proximal humerus anatomy1,2,3 with earlier improvements in motion than traditional stemmed and stemless shoulder arthroplasty systems.1 The data from this study introduces a new industry benchmark, showing that patients who underwent anatomic total shoulder arthroplasty (aTSA) with the Catalyst CSR system experienced high patient satisfaction, little to no pain, significant functional improvements, and very low revision rates that exceed the average data published for similar aTSA implants.

“At five to eight years, we continue to see Catalyst CSR deliver consistent results with clinically significant improvements for patient outcomes,” said lead author Steven Goldberg, MD, orthopedic surgeon at Physicians Regional Healthcare System in Naples, Florida.

“This real-world data further informs the orthopedic community of the effectiveness of a stemless, ellipsoid shaped humeral implant with a multiplanar osteotomy for aTSA,” said Miguel Ramirez, MD, chief medical officer of Catalyst. “It also underscores our focus on delivering a portfolio of clinically proven solutions that challenge the status quo to help improve the quality of life for the many people receiving a shoulder replacement today.”

This retrospective study of prospectively collected data with 5-8 year completed follow up in 206 shoulders in 179 patients with the Catalyst CSR, suggests that a bone sparing approach coupled with a more accurate reconstruction of the proximal humerus can lead to more normal shoulder functionality following shoulder replacement surgery.
