Knee replacement surgery, also known as knee arthroplasty, is a common procedure for people with severe knee pain or damage, typically caused by arthritis or injury. During the surgery, the damaged parts of the knee joint are removed and replaced with artificial components made of metal, plastic, or ceramic.
The goal is to relieve pain, restore function, and improve mobility. Traditional knee replacement surgeries rely on manual techniques for alignment, but newer technologies like robotic assistance are enhancing precision and patient outcomes.
What is the ROSA® Knee System?
The ROSA® Knee System was developed by Zimmer Biomet, a global manufacturer of orthopaedic devices. It was introduced in 2019 as a tool for knee replacement surgeries. This system combines robotic technology with surgeon expertise to improve the accuracy and consistency of knee implant placements.
The ROSA® Knee System is designed to assist surgeons during total knee replacement surgeries. It acts as a surgical guide, providing real-time data and precise measurements to ensure accurate placement of the knee implant. This robotic assistance helps improve the alignment and balance of the knee, potentially leading to better outcomes and a more natural-feeling knee after surgery.
Benefits of the ROSA® Knee System
Better Knee Implant Positioning
ROSA® uses advanced robotic technology to guide surgeons in precisely positioning the knee implant during surgery. It provides real-time data and 3D imaging, allowing the surgeon to make precise adjustments based on the patient’s unique knee anatomy. This level of precision reduces the risk of implant misalignment, which can lead to complications such as pain or uneven wear on the joint.
Customised to Patients’ Knee Structure
No two knees are exactly the same, which is why the ROSA® system offers a personalized approach to knee replacement. Before the surgery, the system helps create a 3D model of the patient’s knee. Surgeons use this model to plan the procedure, ensuring that the implant fits perfectly with the patient’s unique bone and tissue structure. This customization can improve the overall fit and feel of the implant, making it more comfortable and functional for the patient.
Better Alignment of the Knee Joint
Proper alignment of the knee joint is critical for the success of a knee replacement. ROSA® assists surgeons in achieving precise alignment by continuously monitoring the position of the knee and the surgical instruments throughout the procedure. Accurate alignment reduces the strain on surrounding muscles and ligaments, improving joint stability and function. This can lead to a smoother recovery, reduced pain, and a better long-term outcome for the patient, allowing for more natural movement and less wear on the implant.
Step by Step Knee Replacement with ROSA® Knee System
Pre-Surgery Preparation: You’ll undergo pre-operative assessments, including blood tests and consultations with your surgical team. The ROSA® system creates a personalized surgical plan based on your knee scans.
Anesthesia and Positioning: In the operating room, anesthesia is administered to ensure you’re comfortable. You’re then positioned on the operating table, and the surgical area is sterilized.
Incision and Initial Assessment: A small incision is made to expose the knee joint. The ROSA® system provides precise measurements and guides the surgeon in preparing the knee for implant placement.
Implant Placement: The surgeon removes damaged bone and cartilage, then uses ROSA®’s real-time data to place the knee implant accurately, ensuring optimal fit and alignment.
Verification and Final Adjustments: ROSA® provides data to the surgeon to verify the alignment and balance of the implant. Any necessary adjustments are made to ensure the best outcome.
Closing the Incision: Once everything is in place, the incision is closed with sutures or staples, and a sterile bandage is applied.
Conclusion
The ROSA® Knee System offers a modern approach to knee replacement surgery by providing surgeons with real-time data and precise measurements. This system helps improve the accuracy of implant placement and alignment, which can lead to better functional outcomes and potentially reduce complications. By enhancing the precision of each step in the surgical process, ROSA® aims to improve the overall success and longevity of knee replacements. It is a valuable option for patients seeking a more personalised and precise knee replacement procedure.
