Virtual Rounds Take Surgical Training to the Next Level

For years, surgical training has stopped short at watching. Residents observe videos, attend lectures, and shadow procedures. But we all know the reality: what lies beneath the incision, whether in the shoulder, knee, or spine, is complex, three-dimensional, and unforgiving. Traditional videos don’t capture that depth, and passive watching alone can’t prepare us for the operating room. That changes today with the introduction of an immersive virtual cadaver lab that delivers deeper surgical understanding and hands-on practice in a virtual setting.

Introducing Virtual Rounds: A New Paradigm in Surgical Training VR App

We are introducing a new paradigm in surgical education: Virtual Rounds – now residents, for the first time ever, don’t just Watch. They can Practice the procedure, the steps, and go through the process of doing the procedure so they can Perform with the confidence of having done it 10 times.

Step One: Watch, with Depth and Perspective

Our new iPhone app, now available on the App Store delivers surgical videos with enhanced visualization. These aren’t standard recordings; they highlight anatomical depth and the nuances hidden beneath the skin. It’s an immediate upgrade from passive viewing to a richer, more immersive perspective on real procedures.

Step Two: Practice, the Missing Link in Surgical Training

For the first time, what you watch on your phone can be practiced in virtual reality. That exact same case, same steps, same anatomy, same decision points now become available inside our VR platform. You’re no longer limited to imagining the next move or waiting for lab time. Instead, you can rehearse it, hands on, in a risk-free environment.

This is the critical bridge we’ve been missing. It augments videos from passive education into active preparation.

Step Three: Perform with Confidence in the Operating Room

By the time you step into the OR, you’ve already gone beyond observation. You’ve rehearsed the case, understood the anatomical layers, and built the confidence to perform. It’s safer for patients, more empowering for trainees, and a leap forward for surgical education.

Why Virtual Rounds Matter in Orthopedic Surgical Training

Cadaver labs are expensive and limited. Simulators are specialty specific and not readily accessible. Observing alone is incomplete. But now, with affordable VR headsets and a mobile app in your pocket, you can start this journey today. No waiting, no barriers. Watch on your phone, practice in VR, and perform in the OR.

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.

Dr. Ryan Lohre

MGH Staff Surgeon

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.

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.

Immersive Virtual Reality Training for a Junior Orthopaedic Surgery Resident

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.

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.
