TSolution One® Total Knee Application
THINK Surgical® is transforming total knee arthroplasty (TKA) with the FDA cleared TSolution One® Total Knee Application. Fully automated bone preparation completed with accuracy and consistency can give surgeons new confidence that each personalized TKA procedure will be meticulously delivered according to plan.
TPLAN® 3D Planning Workstation
The TPLAN® 3D Planning Workstation is a computer system for preoperative planning. The pre-surgical planning begins when the TPLAN® workstation converts the CT scan of a patient’s joint into three-dimensional surface models of the bones. The surgeon then uses the TPLAN® workstation to select their chosen implant and, using displayed axes of the bones and anatomical landmarks, places the implant components in positions deemed optimal by the surgeon for fit and alignment with the patient’s anatomy. The TPLAN® workstation then creates a pre-operative surgical plan based on those surgeon choices for use by the TCAT® robot.
The TPLAN® workstation provides an open library of implants.
TPLAN® enables the surgeon to explore various surgical plan options and then chose the option they believe is best for each patient.
TCAT® Computer-Assisted Tool
The TCAT computer-assisted tool uses the pre-operative plan created by the surgeon in the 3D Planning Workstation for preparation of the bone cavity and joint surface.
The TCAT is staged in the OR, followed by patient positioning, surgical incision and fixation. Using the bone registration process, the surgeon uses a digitizer to collect points and locate the exact position of the patient’s anatomy for precise surgical implementation.
Under direct control of the surgeon and using controlled, gentle pressure, TCAT prepares the bone with sub-millimeter dimensional accuracy1 as specified by the plan. The specialized bone cutters and other hardware have been developed for accurately preparing the bone to achieve optimal fit of the implant.
Enhanced Surgical Procedure
The TSolution One® Total Knee Application aids surgeons in executing their preoperative plans with precise control, performing hands-free milling for bone preparation. Other surgical systems merely guide the surgeon.
With TPLAN®, the surgeon uses 3D images generated from CT scan data to design a joint replacement procedure tailored to the patient’s unique anatomy. Then, the TCAT® active robot prepares the bone with sub-millimeter dimensional accuracy1 so the surgeon can place and align the implant according to surgeon’s plan.
As a proven clinical system, studies demonstrate improved implant fit and alignment with fewer malalignment outliers when comparing the TSolution One® Total Knee Application to conventional manual joint replacement surgery. The TSolution One® offers several unique advantages:
- Surgeon’s choice of implants
- Open platform surgical system
- Precise pre-surgical planning executed every time
- Sub-millimeter dimensional accuracy1
- High-precision smart-tool technology
- Non-optical technology
CT DICOM data of the patient’s affected joint is uploaded into the TPLAN® 3D Planning Workstation, which converts the data into a three-dimensional virtual bone model2.
The surgeon uses the TPLAN® 3D Planning Workstation to view and position the 3D model of the patient’s bone and joint anatomy, select the ideal implant, and define the optimal placement and alignment.
The TCAT® active robot prepares the bone while the surgeon supervises the procedure, watching the monitor and cutting tool to ensure proper system operation.
The surgeon places the implant and finishes the procedure3.
