How to Design the VR-Assisted Orthopaedia Courses to Enhance Students' Learning Procedural Skills: A Mixed-Methods Crossover Study
This mixed-methods crossover study involving 24 medical students found that while immersive VR offers comparable procedural performance to tablet-based videos for orthopaedic skills, it provides distinct advantages in spatial understanding and focus, suggesting it is best utilized as a complementary tool rather than a complete replacement for conventional training.

Learning to perform medical procedures is a high-stakes skill that requires more than just memorizing steps from a book. It demands a deep understanding of three-dimensional space and the ability to coordinate hands with eyes in a way that feels natural. For decades, medical students have learned these skills by watching instructors demonstrate on real patients or mannequins, a process that is often limited by time, patient safety concerns, and the sheer number of students trying to get a good view. In recent years, educators have turned to technology to solve this problem, experimenting with virtual reality headsets that can place a student inside a simulated operating room. The hope has been that these immersive environments could offer a safe, repeatable way to practice complex movements, potentially making students more skilled and confident than those who rely solely on traditional video screens.
A team of researchers at Chulalongkorn University and Mahidol University in Thailand set out to test whether this immersive technology actually delivers on its promise for orthopaedic training. They focused on two specific, common procedures: applying a cast to a broken forearm and inserting a needle into a knee joint to drain fluid. The study involved twenty-four senior medical students who were learning these skills for the first time. The researchers designed a fair comparison where each student learned both procedures, but they used two different methods. For one procedure, a student would watch a video on a tablet, and for the other, they would use a virtual reality headset to watch the same content in a fully immersive, three-dimensional environment. After learning, the students performed the tasks on real materials, and their speed and technique were measured by an experienced orthopaedic surgeon who did not know which method the student had used.
The results offered a nuanced picture that challenges the idea that newer technology is always better. When the researchers compared the students' final performance, they found that those who learned via the virtual reality headset performed just as well as those who learned from the tablet video. In terms of the final outcome—whether the cast was applied correctly or the needle was placed in the right spot—there was no significant difference between the two groups. The students who used the headset did not finish the tasks faster, nor did they make fewer mistakes in the basic steps of the procedure. This suggests that for learning the fundamental steps of these orthopaedic tasks, a standard video on a screen is just as effective as a fully immersive virtual reality experience.
However, the story changes slightly when looking at how the students moved and thought while performing the tasks. The researchers noticed that students who used the virtual reality headset showed small advantages in areas related to spatial awareness and movement. These students tended to handle their instruments with a bit more fluidity and managed the flow of the procedure slightly better. The immersive nature of the headset seemed to help them visualize the three-dimensional relationships between the tools and the body parts more clearly. It acted like a mental rehearsal space, allowing them to understand the angles and depth of the procedure in a way that a flat screen could not quite replicate. Yet, these advantages were modest and did not translate into a dramatic improvement in the overall success of the procedure.
The study also looked at how the students felt about the technology. When asked to rate their experience, the students generally agreed that the virtual reality system was useful and that it helped them focus. They reported that the headset blocked out distractions from the room, allowing them to concentrate deeply on the lesson. Many felt that the ability to look around and see the procedure from different angles helped them understand the anatomy better. Despite these positive feelings, the students also pointed out practical hurdles. Setting up the equipment, adjusting the controllers, and dealing with occasional blurriness in the image created friction that slowed them down. Some students noted that while the experience was engaging, it required a bit of help to get started, and they were not entirely sure they would use it again without that support.
Ultimately, the researchers concluded that virtual reality is not a magic replacement for traditional learning or hands-on practice. Instead, it serves best as a specialized tool for specific types of learning. For procedures that require a strong sense of three-dimensional space, the headset offers a clear benefit by helping students visualize the task in a way that feels real. But for learning the basic steps of a procedure, a simple video works just as well. The study suggests that the future of medical education lies not in choosing one technology over the other, but in knowing when to use each. Virtual reality should be used to enhance understanding of complex spatial tasks, while traditional methods remain effective for general instruction. The technology is ready to be part of the classroom, but only if educators understand its specific strengths and the practical logistics required to make it work smoothly.
