Software-guided Knee Surgery helps to ensure better alignment and accurate results in total knee replacement
The Brainlab pinless solution for software-guided surgery provides visual guidance for alignment and placement of the implants intraoperatively.
The finely adjustable cutting block allows for live navigation of the placement of femoral implant components without additional pin placement in the bone. The cutting block can be pre-placed with an easy-to-use template and easily adjusted with the innovative mechanism.
The software provides real time feedback of the cutting block position and enables a less invasive approach for knee replacement procedures.
The positioning of the cutting block is one of the most important factors for a successful knee replacement surgery. The Alignment Verification Workflow is designed to be used with any conventional instrumentation and allows for verification of the cutting block position and final cut results without any additional pin fixation. The software requires only a quick 3 step registration that typically takes less than 30 seconds.
The Alignment Verification Workflow is also a great tool to support unicondylar knee replacement procedures and revision surgery*.
Today’s active patients demand a natural-feeling knee, so attention to soft tissue has become increasingly important in total knee arthroplasty. The knee navigation application from Brainlab is designed to assess and quantify the soft tissue envelope, including gap balancing and balance information through the entire range of motion. Brainlab supports the majority of available implants with implant-specific and universal workflow options.
The kinematic analysis helps the surgeon to achieve optimal leg alignment balance. The Brainlab Ligament Balancing functionality allows for an analysis of the initial and final biomechanical situation and offers real time information on the outcome values during knee replacement surgery.
Documentation is an important element for communication between surgeons and patients. Several independent studies over the years have shown that using orthopedic navigation for knee replacement surgery reduces the number of outliers and improves overall alignment, leading to better performance and longer life of the implants¹.
