Zimmer Biomet received 510(k) clearance for a shoulder feature for its Rosa surgical robot, positioning it as the first company to market for robotic-assisted shoulder replacements. The Food and Drug Administration’s decision came earlier than expected, Evercore ISI analysts wrote in a research note. They had expected a mid-year clearance and launch. Competitor Stryker plans to launch a shoulder feature for its Mako robot at the end of the year, CEO Kevin Lobo said in an earnings call last month.
