This study introduces a computer-aided technique for bi-unicompartmental knee replacement, offering a less invasive surgical option. This approach aims to preserve natural anatomy and improve functional outcomes for knee osteoarthritis patients.

Area of Science:

  • Orthopaedic Surgery
  • Biomedical Engineering
  • Knee Osteoarthritis Treatment

Background:

  • Bi-unicompartmental knee implants are not widely reported, and surgeons are skeptical despite theoretical benefits.
  • This approach offers maximal preservation of normal anatomy, potentially improving gait, muscle activity, and proprioception.
  • Computer-aided knee replacement surgery shows promise for improved limb alignment and kinematics.

Purpose of the Study:

  • To present a computer-aided technique for bi-unicompartmental knee replacement.
  • To offer a less invasive alternative for knee replacement surgery.
  • To highlight the potential benefits of preserving natural anatomy and improving functional outcomes.

Main Methods:

  • Utilizing computer-aided technology for precise surgical planning and execution.

  • Performing bi-unicompartmental knee replacement with intraoperative checks of implant position and ligament balance.
  • Focusing on a less invasive surgical approach compared to traditional methods.

    • Main Results:

    • The presented technique allows for a less invasive knee replacement procedure.
    • Computer-aided surgery enables verification of implant placement and ligament stability throughout the joint's range of motion.
    • This method addresses potential complications associated with surgical failures in traditional knee replacements.

    Conclusions:

    • Computer-aided bi-unicompartmental knee replacement is a viable, less invasive surgical option.
    • The technique facilitates maximal preservation of native knee anatomy, potentially enhancing functional recovery.
    • Further adoption may overcome surgeon skepticism and improve patient outcomes in knee osteoarthritis treatment.
