Surgical Classroom
Pressemitteilung: Precision OS mit Sitz in Vancouver hat sich mit 10 nordamerikanischen Universitäten und medizinischen Einrichtungen zusammengetan, um ihre High-Fidelity-Virtual-Reality-Trainingsplattform für orthopädische Chirurgie in das chirurgische Klassenzimmer zu bringen.

Precision OS envisions a future where surgeon trainees (residents) everywhere can receive the highest quality orthopedic training with real-time feedback, augmenting the cadaveric experience. To get there, they’re using the power of virtual reality technology.

Virtual Reality bietet beispiellose chirurgische Immersion, ungehindert von realen Umständen und ohne das Risiko, Patienten zu verletzen. Die Precision OS-Plattform simuliert Operationssaal-Erfahrungen, von den verwendeten virtuellen Werkzeugen bis hin zur Anatomie des Patienten. Dies wird durch benutzerspezifisches Metrik-Feedback gemeinsam verstärkt, um Chirurgen zu befähigen, durch wiederholtes Üben und personalisiertes Lernen Höchstleistungen zu erzielen.

“Virtual reality has the potential to positively impact and advance the way surgery residents are trained by offering more frequent and in-depth operating room experience. We are looking forward to exploring this technology and introducing the Precision OS platform to our residents and fellows.” Dr. Joaquin Sanchez-Sotelo, Professor in der Abteilung für orthopädische Chirurgie der Mayo Clinic

Einzigartig am Precision OS-System ist die Breite und Tiefe der Schulungsmodule. Die Bewohner können einen Eingriff unter einer Vielzahl von sich ändernden Bedingungen üben, um sicherzustellen, dass sie mit den Fähigkeiten vorbereitet sind, die sie benötigen, um potenzielle Komplikationen in einer echten Operation zu bewältigen. Erkrankungen wie Arthritis und Alter können die Vorgehensweise bei Operationen mit Implantaten verändern. Während es keine Garantie dafür ist, dass ein Bewohner in einem traditionellen Ausbildungsprogramm solchen chirurgischen Erfahrungen ausgesetzt ist, ist dies bei VR der Fall.

Die Precision OS VR-Plattform bietet Chirurgen-Auszubildenden die Möglichkeit, mehr OP-Erfahrung zu sammeln, als sie es normalerweise in einer traditionellen Arztpraxis tun würden. Von kleinen Komplikationen bis hin zu schwerwiegenden Fehlern können die Bewohner die Operation hautnah miterleben, indem sie einfach ein Headset aufsetzen.

Mehrere hundert Chirurgen-Auszubildende an 10 medizinischen Einrichtungen in den USA und Kanada werden diese Technologie nun in ihren Residency-Programmen hautnah erleben. Precision OS wird für die orthopädische Chirurgie-Ausbildung verwendet bei:

• The Mayo Clinic
• The University of British Columbia
• The Sunnybrook Hospital at the University of Toronto
• The Pan Am Clinic Foundation
• Western University
• McGill University
• Dalhousie University
• The Boston Shoulder Institute
• The University of Mississippi Medical Center.

Das Precision OS-Team arbeitet auch mit Dr. John Costouros, MD FACS, einem orthopädischen Chirurgen und Assistenzprofessor an der Stanford University, zusammen, um die virtuelle Realität in der Ausbildung angehender Chirurgen zu testen.

Dies ist das erste Mal, dass diese Qualität der High-Fidelity- und immersiven VR-Technologie für ein so intensives chirurgisches Training verwendet wird.

“The next generation of surgeons will have to learn advanced skills and decision-making with limited time for their training. Virtual reality offers an impactful way to create value by improving surgical skill and reducing errors. Precision OS will deliver value to all stakeholders in healthcare: educators, industry, hospitals, insurers, and patients. The timing of such a technology could not be more perfect!” Dr. Jon JP Warner, Gründer des Boston Shoulder Institute, New England Shoulder and Elbow Society, The Codman Shoulder Society und ehemaliger Präsident der American Shoulder and Elbow Surgeons

Precision OS bietet eine verbesserte Lernumgebung für orthopädische Auszubildende, indem es den Zugang zur chirurgischen Praxis verbessert. Über ein Headset und Handheld-Sensoren können die Bewohner den Operationssaal jederzeit und überall betreten. Dies erhöht das Übungsvolumen und verbessert die Ergebnisse der chirurgischen Fähigkeiten in fallbasierten Szenarien.

“VR training is the way of the future. It will enhance patient care by having a more skilled and well-prepared surgeon. The software and training unit of Precision OS is brilliantly put together and is a major advance for our residency and fellowship training program!” Dr. Peter MacDonald, Professor und Leiter der Orthopädie an der University of Manitoba

Und jedes Mal, wenn ein Assistenzarzt ein Precision OS-Trainingsmodul beginnt, taucht er in eine lebensechte chirurgische Erfahrung ein. Der virtuelle Patient reagiert auf Erfolge und Fehler in einem Eingriff und ermöglicht so den Auszubildenden, aus ihren Fehlern zu lernen. Diese simulierte Umgebung ist ein entscheidender Unterschied zwischen VR und traditionellem chirurgischem Training, da in der realen Chirurgie keine Fehler erlaubt sind, um zu verhindern, dass Patienten Schaden genommen werden. Aber genau diese Möglichkeit des Fehlers erfordert von den Auszubildenden erhöhte Aufmerksamkeit und Konzentration und schafft eine aktivere, effektivere und wirkungsvollere chirurgische Lernerfahrung. Dies macht Precision OS einzigartig.

Während und nach einem Eingriff erhalten die Bewohner detaillierte Leistungskennzahlen, damit sie ihre chirurgischen Fähigkeiten in Echtzeit beurteilen und Verbesserungspotenziale identifizieren können. Dieses sofortige Feedback ermöglicht spürbare Leistungsverbesserungen und erhöht die chirurgische Präzision schnell.  

“Our core agenda has always been to combine surgical education and cognitive skill in a portable, efficient, and immersive learning experience.” Dr. Danny Goel, CEO und Mitbegründer von Precision OS und orthopädischer Chirurg an der University of British Columbia

Precision OS ist wegweisend für Innovationen in der orthopädischen chirurgischen Ausbildung und die internationale medizinische Gemeinschaft nimmt dies zur Kenntnis. Im vergangenen Jahr sicherte sich Precision OS $2.3M an Finanzierung unter der Leitung von AO Invest, dem Risikokapitalzweig der Schweizer orthopädischen Bildungs- und Forschungsorganisation AO Foundation.

Das Unternehmen wurde auch für die Technology Impact Awards nominiert und war Halbfinalist der Orthopaedic Research Society.

“This is only the beginning of what may be a complete disruption of how we learn and train surgeons. To be at the cutting edge of introducing this technology, with a focus on demonstrating its value, is a social responsibility for us at Precision OS. Virtual reality is an exciting and innovative area of technology that can influence surgeons and their patients around the world.” Dr. Goel

Precision OS is a software company developing the most high-fidelity virtual reality platform for surgeons to practice specific procedures. Their focus on the critical elements of surgery haptics and metric feedback provides for an unparalleled educational experience. In addition, their pre-operative planning tool eliminates the trial and error associated with fracture care through an immersive interaction with the patients’ images. This, combined with their carefully selected team, provides the domain expertise one would expect to change the delivery of Orthopedic care globally.

21 Months of Automated VR Data

MAJOR ACADEMIC ORTHOPAEDIC RESIDENCY PROGRAM

How self-directed VR practice fills the seams of the clinical day and produces measurable learning trajectories—completely automatically.

Executive Summary:

Over a 21-month period, 30 orthopaedic residents integrated immersive VR into their training curriculum. With a simple, weekly requirement for residents to practice in headset, the platform seamlessly captured over 88,000 structured data points across 2,566 practice sessions. The resulting data proved that when residents have access to high-fidelity, frictionless simulation and are motivated, they will hone their skills and demonstrate clear performance improvements.

Frictionless Adoption: Practice doesn't compete with clinical time. The data revealed that 45% of all sessions happened organically during lunch breaks or on weekends.

Comprehensive Coverage: Usage wasn't limited to a single subspecialty. Residents attempted 61 distinct cases across 27 procedure modules, proving active engagement from Foundations & Anatomy to Complex Trauma.

Measurable Improvement: The platform didn't just track usage; it tracked skill acquisition. Across 288 scored playthroughs, longitudinal data showed a clear performance signal, with residents demonstrating an average positive learning delta of +0.36 over time.

From Uncertainty to Execution

“You already have a plan, now you’re just executing it.”

The Story: Bridging the "Intern Gap"

Dr. Andrew Maeso recognizes the steep reality of residency: “As an intern, you are thrown into the fire.” For him, the hurdle wasn’t just the surgery—it was the invisible mechanics (positioning, X-ray angles, and workflow) that move too fast to learn in a high-pressure OR.

The Solution: Access Over Policy

By bringing the PrecisionOS ecosystem home, Dr. Maeso replaced passive YouTube watching with active mental rehearsal. This allowed him to arrive in the OR with the “steps” already hard-coded into his muscle memory.

The Game Changer: Personal headsets issued for at-home, 24/7 training.

Clinical Focus: Mastery of Antegrade Femoral Nails and Shoulder Arthroscopy.

Program Growth: Experience led to secured funding for all incoming residents.

From Resident to MGH Staff Surgeon

“Prepare like it matters. Because in the OR—it does.”

The Story: The Currency of Trust

Dr. Ryan Lohre’s trajectory changed during a complex pediatric case that had already seen two failed attempts by tenured surgeons. While textbooks offered the theory, Dr. Lohre used VR to master the 3D spatial intelligence required to build a mental model of the deformity and navigate C-arm imagery in real-time.

The Solution: The 18-Minute Sandbox

The night before surgery, Dr. Lohre rehearsed the procedure four times in VR from his own home. This high-fidelity rehearsal allowed him to arrive in the OR functioning at 80-90% proficiency, compared to the typical 10-20% for a resident facing a new, complex procedure.

The Game Changer: 18 minutes of at-home VR prep for a complex pediatric case.

Clinical Focus: Spatial intelligence for C-arm interpretation and screw trajectory.

Program Growth: Transitioned from trainee to Staff Surgeon at Mass General.

Teaching with Surgical Efficiency

“I let the junior resident do more than ever before—and still finished on time.”

The Story: Reclaiming the OR

While at West Virginia University (WVU), Dr. Barry McDonough faced a universal challenge: balancing resident education with strict OR efficiency. By the time residents step into the OR, foundational skills like camera handling and triangulation should be second nature—not a distraction that slows down the case.

The Solution: Independent Preparation

Residents were assigned just 10 minutes of asynchronous VR training per week. This allowed them to master the “invisible” basics of arthroscopy on their own time. With an average of 17 sessions completed during the pilot, residents arrived with a mental roadmap that translated into immediate technical fluency.

The Game Changer: Asynchronous prep—residents train independently at home.

Clinical Focus: Mastery of triangulation, scope control, and anchor placement.

Program Growth: Model expanded across trauma, spine, and upper extremity.

Dr. Charlie Spieser

Orthopedic Resident

Mastering the Visuo-Spatial Gap

“VR practice shifts questioning from case generalizations to technique refinement.”

The Story: From Application to Confidence

Charlie Spieser highlights a universal resident hurdle: the high-stress transition from “book knowledge” to real-world execution. Early in training, the fear of making irreversible decisions can lead to hesitation. To bridge this gap, Charlie utilized VR as a daily resource for kinetic learning and anatomical association.

The Solution: Refining Spatial Intelligence

Unlike textbooks or passive videos, PrecisionOS allowed Charlie to practice high-stakes approaches—such as the anterior total hip—in a guided, 3D environment. This repetition provided a “safe sandbox” to identify why errors occurred, building the visuo-spatial confidence required to navigate complex anatomy before ever entering the OR.

The Game Changer: Daily Integration—normalized as an expected program resource.

Clinical Focus: Anterior Total Hip and Deltopectoral surgical approaches.

Program Growth: Nuanced Mentorship—shifting focus to specific faculty preferences.

Andres D Maeso, DO, Michael R McDermott, DO, Jerrod A Steimle, DO

How consistent iVR training accelerates technical fluency and attending trust for first-year residents.

Executive Summary: This case study follows a first-year resident’s integration of immersive VR (iVR) into their surgical curriculum. By dedicating consistent training time to virtual modules, the resident was able to master procedural steps and receive real-time feedback in a risk-free environment before ever stepping into the operating room. The study highlights that this deliberate practice led to a “noticeable improvement in overall efficiency” and significantly increased the attending’s trust and confidence in the resident’s intraoperative capabilities.

Source Attribution: Immersive Virtual Reality Training for a Junior Orthopaedic Surgery Resident, Journal of Orthopaedic Experience & Innovation (2025).

Muscle Memory Development: The repetitive nature of immersive VR (iVR) training, combined with constant real-time feedback, allows technical surgical steps to become deep-seated muscle memory.

Measurable Efficiency Gains: Residents utilizing the platform observe a "noticeable improvement" in overall efficiency and technical proficiency when performing complex orthopedic procedures.

Accelerated Attending Trust: Preoperative rehearsal in a virtual environment significantly increases attending surgeon confidence, directly leading to increased autonomy for the resident in the operating room.
