A novel surgical system brings active robotic precision to total knee arthroplasty (TKA) and total hip arthroplasty (THA).

The THINK Surgical (Fremont, CA, USA) TSolution One Surgical System is based on an innovative robotic platform that enables a surgeon to create a patient's personalized pre-surgical joint replacement plan using computerized tomography (CT)-based three dimensional (3D) planning and an open-source implant library in order to achieve an optimized surgical plan. The TSolution One uses two revolutionary technologies that work in synergy to bring an exceptional degree of precision and accuracy to total joint replacement:

The TPLAN 3D planning workstation is a computer system for preoperative planning with 3D modeling and simple point-and-click control. Pre-surgical planning begins, for example, when the TPLAN converts the CT scan of the patient’s hip joint into a 3D surface model of the femur. The surgeon then selects an implant from the open library of legally-marketed implants and places it along the axes of the bone, with the help of anatomical landmarks, matching it to the patient’s anatomy so as to achieve optimal fit and alignment.

During surgery, The TCAT computer assisted tool uses the pre-operative plan created by the surgeon for preparation of the bone cavity and joint surface, removing diseased bone and preparing the bone cavity and joint surface with sub-millimeter dimensional accuracy. The surgeon uses a digitizer to collect points and locate the exact position of the patient’s anatomy for precise surgical implementation using a range of specialized drill bits. If bone motion occurs, the system is halted, and the registration system helps the surgeon quickly recover bone position and resume surgery.

“We are pleased to offer one of the most advanced technologies in Total Knee Replacement through the TSolution One Surgical System to the European market and other countries that rely on the CE Mark,” said John Hahn, CEO of THINK Surgical. “Obtaining the CE Mark represents a key milestone towards continuing the global commercialization of our differentiated robotic technology, and our commitment to improving patients' lives and partnering with surgeons to transform orthopedic surgery.”
