Stryker’s Soft Tissues Guided Motion knee philosophy is enabled by five unique design features found in the Triathlon knee system.
More infoThe addition of the Mako Total Knee application with Stryker’s market-leading Triathlon Total Knee System expands the current Mako offering to provide a comprehensive solution in the robotic-arm assisted reconstructive service line. The total knee application was developed based on the Mako Partial Knee application. The three core features: enhanced planning, functional implant positioning, and robotic-arm assisted bone preparation, as well as the procedural workflow were adapted to enable a Mako Total Knee procedure with Triathlon.
CT data is segmented to create a 3D model of the patient’s bony anatomy. The total knee application allows a surgeon to manipulate the Triathlon implant on the patient’s virtual 3D anatomy taking into account the 6 degrees of freedom, implant alignment in all three planes, and consider key anatomic landmarks such as the transepicondylar axis, posterior condylar axis and the mechanical axis during planning.
After assessing the patient’s ligament tension, gap analysis, and limb alignment, surgeon controlled intra-operative adjustments can be made to the pre-operative plan in both flexion and extension before bone preparation.
The Mako Total Knee application does not require cutting blocks, A/P sizing guides, ankle cradles, or intramedullary rods for bone preparation. Similar to Mako Partial Knee, the total knee application creates a stereotactic boundary which assists the surgeon in executing both the tibial and femoral bone resections to plan. The stereotactic boundary has the potential to protect essential anatomical structures of the knee during bone preparation including the PCL and the popliteal artery.
The Mako Total Knee Arthroplasty application is compatible with Stryker’s Triathlon Total Knee System that has over a decade of proven performance in both Australia and New Zealand, recording one of the highest published survivorship rates of all knee prostheses in the market at 96.6%1 and 97.4%2 respectively after ten years.
Stryker’s knee philosophy is focused around ‘Soft Tissue Guided Motion’ where the implant respects the soft tissue envelope of the patient and works with the body rather than simply within it. This results in patients being able to experience a high flexion and high functioning knee, and quicker post-surgery recovery3.
Mako robotic-arm assisted Total Knee Arthroplasty has the potential to increase the accuracy of TKA bone cuts and component placement to plan, even for an experienced user of manual instrumentation who is new to robotic technology.4
Adequate soft tissue protection is achieved using Mako robotic-arm assisted surgery for Total Knee Arthroplasty. It offers protection of the medial collateral ligament (MCL), lateral collateral ligament (LCL), posterior cruciate ligament (PCL), and patellar ligament with no visible evidence of disruption of any of the ligaments. Tibial subluxation was not required for tibial cutting, which may reduce ligament stretching. All cases were left with a bone island on the tibial plateau, which protected the PCL. In addition, patella eversion was not required for visualization.5
