A novel miniature, bone-attached robotic system was developed for joint arthroplasty. This image-free system accurately prepares bone cavities for implants, enabling minimally invasive procedures.

Area of Science:

  • Orthopaedic surgery
  • Robotics in medicine
  • Biomedical engineering

Background:

  • Joint arthroplasty procedures require precise bone preparation.
  • Current methods may lack accuracy and necessitate external tracking systems.
  • Minimally invasive techniques and advanced implant designs are emerging.

Purpose of the Study:

  • To report the design and implementation of a new active, miniature, bone-attached robotic system.
  • To demonstrate the system's capability in preparing bone cavities for implants during joint arthroplasty.
  • To evaluate the feasibility of an image-free, intra-operative planning robotic system.

Main Methods:

  • Development of a miniature, bone-attached robotic system with high and low-level control.
  • Implementation for Patellofemoral Joint Replacement surgery.
