Hugo RAS vs mBos TKA System in 2026

Hugo RAS

Medtronic's Hugo RAS is a modular, multi-port teleoperated robotic-assisted-surgery system and the main commercial competitor to Intuitive's da Vinci. It is CE-marked in Europe (urology and gynecology, October 2021) and US FDA-cleared for urology only (December 2025: prostatectomy, nephrectomy, cystectomy); US general-surgery and gynecology indications are planned but not yet cleared.

It is teleoperated with no shipped intraoperative AI. Medtronic does not disclose a Hugo installed-base count, so DEPLOY records honest absence rather than an invented number. It is enterprise B2B equipment; there is no consumer price.

mBos TKA System

The Monogram mBos TKA System is a robotic total-knee-arthroplasty platform from Monogram Technologies, a Zimmer Biomet subsidiary since October 2025. It is the autonomy-boundary case of DEPLOY's surgical cluster: unlike the AI-augmented, surgeon-controlled systems (Stryker Mako, Smith+Nephew CORI, Zimmer Biomet ROSA), where the surgeon makes the cuts, the cleared mBos is semi-autonomous, with a robotic arm (built on a KUKA arm) executing the bone cuts itself under AI control within a surgeon-approved, patient-specific CT-based plan and active surgeon supervision.

There is no consumer price: it is pre-commercial enterprise surgical equipment that has not sold any units. Several verified-vs-claimed cap-flags matter. It received FDA 510(k) clearance on March 17, 2025, but the exact K-number could not be independently verified, and the 'semi-autonomous' characterization is sourced to Zimmer Biomet and trade coverage rather than the FDA letter (Monogram's own clearance release described it more softly as robotic-assisted TKA).

A separate fully-autonomous, hands-free, saw-based version is not FDA cleared and remains in development, targeted around late 2027 or 2028; its first live-patient procedure (July 26, 2025, Ahmedabad, India) was under an India CDSCO 102-procedure investigation, not US FDA, a single index case with no verified peer-reviewed outcomes. Monogram was founded by orthopedic surgeon Dr.

Doug Unis (chief medical officer and founder, not CEO; the pre-acquisition CEO was Benjamin Sexson) and was acquired by Zimmer Biomet at about $168M enterprise value plus contingent value rights, with commercialization alongside Zimmer Biomet implants targeted for early 2027. The registry records it at research maturity: cleared but pre-commercial, with its headline fully-autonomous capability still in development.
