THINK surgical TSolution-One^® (Robodoc) total knee arthroplasty

Area of Science:

• Orthopedic Surgery
• Robotics in Medicine
• Biomedical Engineering

Background:

• Robotic systems are increasingly used in total knee arthroplasty (TKA) to improve surgical accuracy.
• The THINK Surgical TSolution-One system is an image-based, active-autonomous robotic milling platform designed for precise implant placement.
• Current literature lacks extensive long-term data on the efficacy of robotic-assisted TKA.

Purpose of the Study:

• To describe the surgical technique of the TSolution-One system for TKA.
• To outline the limitations and potential complications associated with this robotic approach.
• To present the clinical and radiological outcomes of robotic-assisted TKA using the TSolution-One system.

Main Methods:

• The study describes the TSolution-One surgical technique, emphasizing image-based preoperative planning and robotic milling for customized bone resection.
• Factors contributing to accuracy include customized distal femoral resection, precise femoral rotational alignment, error minimization, and bone temperature maintenance.
• The methodology focuses on the application of the robotic system in TKA procedures.

Main Results:

• The TSolution-One system facilitates accurate implant component positioning through image-based planning and robotic milling.
• Key benefits include customized bone resection and precise rotational alignment, minimizing errors.
• While accuracy is demonstrated, long-term efficacy data, radiation risks, surgical duration, and cost-effectiveness require further investigation.

Conclusions:

• The TSolution-One system provides a method for achieving accurate implant positioning in TKA.
• Further research is necessary to establish the long-term clinical benefits and address unanswered questions regarding safety and cost.
• High-quality, long-term data is crucial for validating the widespread adoption of robotic-assisted TKA.
