VR CHECK PLANNING
BEFORE SURGERY
Strategy - Simulation - Individual planning
Preoperative VR assessment is part of the three stages of MATRIX arthroplasty and supports the surgeon in planning knee or hip replacement.
Patient selection for MATRIX arthroplasty
The correct selection of a patient is our top priority for a successful knee or hip arthroplasty intervention.
Suitability for joint replacement is assessed individually, taking medical history, symptoms and clinical examination into account.
In our Orthopaedic Dept., we use specific algorithms and best practice, based on American Association of Orthopedic Surgeons (AAOS) evidenced base to standardize patient selection based on medical history, severity of symptoms, degree of arthritis, and any previous failures or treatment modalities.
The predictive algorithm model requires effective communication between patients and surgeons and the development of a trusting relationship that promotes the integration of data such as patient preferences and needs. This is in conjunction with the analysis of the therapeutic protocol, the likelihood of complications, risks, benefits, and possible alternative solutions before making informed decisions.
The decision-making process is based on validated predictive factors, such as demographic data or preoperative outcome measures reported by the patient.
Preoperative planning and modelling
Preoperative planning and modeling involve three-dimensional visualization of anatomical variations, size of axial deformity, dimensions and localization of osteophytes, demonstrating postoperative alignment of the limb, the positioning and size of the implant, as well as the balance of soft tissues. Preoperatively, implant sizes can be predicted using specialized algorithms based on demographic data such as gender, height, weight, age, ethnicity/race, and shoe size.
Digital patient information
Three-dimensional preoperative planning and modeling serve as the primary source of digital information for the patient. Wearing specially designed 'virtual reality' glasses, the patient is immersed in a virtual landscape and can observe anatomical details of their affected joint in three-dimensional space. This allows them to see the appropriate choice of implants and understand how their 'new' joint will function postoperatively.
Virtual surgery simulation
Artificial intelligence-based virtual reality is currently the most valuable tool for teaching and surgical simulation, operating in a 360-degree viewing mode.0 as it provides access to all levels of knee and hip arthroplasty surgeries and beyond.
Surgeons can simultaneously assess decisions regarding the implant, make the final selection, and complete the intervention and final implantation, monitoring the effectiveness of the procedure. This minimizes errors during the surgical process and the time of completion, utilizing minimal surgical equipment and tools. They can also receive feedback on key steps such as osteotomy planning, implant placement, sizing, assessment of virtual range of motion, and void balancing.
They can acquire procedural learning and surgical experience without direct supervision from another surgeon, as well as collect data at all stages of the educational process.
In reality, they can safely perform the surgical procedure in a virtual environment before even reaching the actual intervention process. They can identify potential errors and pinpoint surgical difficulties.

How planning connects to the next steps
Digital preoperative planning brings together information before knee or hip replacement. Virtual imaging supports presentation of the plan and discussion with the patient. The next stage is explained in the Surgery Process section, while recovery monitoring tools relate to postoperative care.
Questions about preoperative VR assessment
What comes before digital planning?
Medical history, clinical assessment and the imaging requested by the surgeon come first. This information provides a basis for assessing whether the proposed procedure is suitable and for organising the planning process.
Does VR planning mean that a robot will be used?
Preoperative planning and the choice of surgical technology are separate steps. The surgeon selects the appropriate technique and supporting tools based on the assessment and the individual patient's needs.
Do I need to choose a technique before my visit?
The visit is an opportunity to discuss options and ask questions. Assessment of your own situation comes before a final decision. You can explore the 3 Core Phases to help prepare your questions.
