THINK Surgical, Inc. is committed to the future of orthopedic surgery and to improving patient care through the development of leading-edge precision technology.
TSolution One® Surgical System
The TSolution One Surgical System combines two exclusive innovations to produce a revolutionary technology. The system consists of TPLAN®, a 3D pre-surgical planning workstation and TCAT®, a computer assisted tool. These revolutionary technologies combine to provide the future of total joint replacement surgery.
We partner with expert surgeons. Our goal is to make sure their surgical expertise can be fully leveraged and their surgical plans carried out exactly as defined.
The system is cleared by the United States FDA for orthopaedic surgical procedures for the hip. The TSolution One core technology has been used in thousands of successful total joint replacements for both hip and knee worldwide.
Improve Surgical Outcomes
With TPLAN, use 3D images generated from CT scan data to design a joint replacement procedure tailored to the patient’s unique anatomy. Then, enlist the TCAT tool to mill the bone with sub-millimeter accuracy so the surgeon can place and align the impact exactly according to surgeon’s plan.
As a proven clinical system, studies demonstrate improved implant fit, fill and alignment with fewer malalignment outliers when compared to conventional manual surgery. Other advantages include:
- Better bone ingrowth for THA1
- Less loss of bone density due to better transfer of body weight for THA2
- Decreased incidence of leg length discrepancies for THA3
- Sub-millimeter dimensional accuracy4
- Precision milling for improved alignment5
- 95% bone to implant contact for THA1
- Reduced canal penetration compared to conventional surgery
- Less blood loss compared to conventional surgery
From the surgeon’s perspective
This technology brings the precision and accuracy found in the engineering world into the operating room. It allows the surgeon to more accurately plan and perform joint replacement surgery. .
TPLAN enables the surgeon to explore several surgical plan options without risk to the patient or expending valuable surgical time. The surgeon can move and rotate implant options and change implant size until he finds the best fit in three dimensions. .
I have gained a newfound confidence when using the TSolution One Surgical System. No more anxiety waiting for the PACS post-operative films- the results are just as planned every time. .
One of the things that I’ve always liked about the THINK Surgical system is that it’s an active robotic system. Other systems are passive in that they guide the surgeon in performing the surgery. The THINK Surgical system will perform your preoperative plan on its own, under your guidance.
The TSolution One Active Robotic system is the most sophisticated and accurate surgical tool I have used in more than 30 years of a total joint replacement practice. It will lead the way to replace mechanical instruments- including surgical saws and reamers, for common arthroplasty procedures, while enhancing the accuracy of our reconstructions.

Technology
- TPLAN®, a 3D planning workstation for preoperative planning
- TCAT®, a computer-assisted tool that executes the pre-surgical plan
These revolutionary technologies combine to provide the future of total joint replacement surgery.
TPLAN®
The pre-surgical planning begins when the TPLAN converts the CT scan of the patient’s hip joint into a three-dimensional surface model of the femur. The surgeon selects an appropriate implant and places it along the axes of the bone with the help of anatomical landmarks.
The system has an open library of legally-marketed implants for the US and EU. The surgeon can manipulate the implant to achieve optimal fit and alignment for the patient’s anatomy.
TPLAN enables the surgeon to explore several surgical plan options without risk to the patient or expending valuable surgical time.
TCAT®
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.
TCAT is staged in the OR, followed by patient positioning, surgical incision and fixation. Using a patented process for bone registration, 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 mills the bone with sub-millimeter accuracy as specified by the plan. The specialized drill bits and other hardware have been developed for accurately preparing the bone to achieve optimal fit of the prosthetic implant.
If bone motion occurs, a bone motion monitoring system halts the system. The registration system then allows the surgeon to quickly recover bone position and resume the surgery with no loss of precision.
TCAT mills cavities for hip implants and planes the femoral and tibia surfaces for knee implants.
How it Works
Step 1
The pre-surgical planning begins with a detailed CT scan of the patient’s joints. The TPLAN 3D Planning Workstation converts the CT data into a three‑dimensional virtual bone image.

Step 2
The surgeon uses the TPLAN 3D Planning Workstation to view and manipulate the 3D model of the patient’s bone and joint anatomy, select the ideal implant, and define the optimal placement and alignment.

Step 3
The TCAT Computer-Assisted Tool uses the patient’s personalized plan to mill and prepare the bone with sub-millimeter accuracy.

Advantages
Active Robotics
Not all robotic surgical systems are the same. The TSolution One® Surgical System is the only active robotic system for orthopaedic surgery.
Our active robotic system aids surgeons in executing their preoperative plans with essentially effortless control, performing autonomous milling for bone preparation. Other surgical systems merely guide the surgeon.
Unique Advantages
As a proven clinical system, studies demonstrate improved fit, fill, and alignment when comparing the TSolution One® to conventional joint replacement surgery. The TSolution One® features:
- Personalized pre-surgical plans
- Surgeon’s choice of implants*
- A complete robotic solution for stem and cup
- Open platform surgical system
- Sub-millimeter dimensional accuracy4
- Elimination of less accurate templates and jig-based technology
- Non-optical technology
- Precise computer-assisted preparation of the bone cavity for THA
* Legally marketed implants in the US.
Clinical Results
Research on long-term outcomes of hip replacement procedures shows that a more precise implant fit leads to better ingrowth of bone1 and decline in loss of bone density due to better transfer of body weight2.
