Think Surgical Inc., of Fremont, Calif., won good news from the U.S. FDA, which cleared the company's Tsolution One total knee application for use in total knee arthroplasty (TKA). The Tsolution One total knee application includes computed tomography-based 3D presurgical planning software, providing surgeons the ability to design and prepare the patient's knee joint replacement plan. During surgery, the physician puts the patient's pre-planned procedure using the robot into effect, with the goal of precisely placing the knee implants.
