Arthroscopic and computer-assisted high tibial osteotomy using standard total knee arthroplasty navigation software

Area of Science:

• Orthopedic Surgery
• Biomechanical Engineering
• Medical Technology

Background:

• Opening-wedge high tibial osteotomy (OWHTO) is crucial for treating varus gonarthrosis and malalignment.
• Accurate mechanical axis correction is vital for successful OWHTO outcomes.
• Precise preoperative planning and surgical technique are essential but challenging.

Purpose of the Study:

• To describe a novel technique for arthroscopic and computer-assisted OWHTO.
• To utilize readily available total knee arthroplasty navigation software as an intraoperative goniometer.
• To provide surgeons with a reliable tool for accurate mechanical axis correction.

Main Methods:

• Arthroscopic approach for OWHTO.
• Integration of computer-assisted navigation (total knee arthroplasty software) for real-time guidance.
• Utilizing navigation software as an intraoperative goniometer to measure correction degree.

Main Results:

• The described technique allows for accurate and reliable intraoperative guidance.
• Computer-assisted navigation provides real-time feedback on the degree of correction.
• This method enhances precision in achieving the desired mechanical axis correction.

Conclusions:

• The arthroscopic, computer-assisted OWHTO technique offers a valuable tool for surgeons.
• It improves accuracy and reliability in correcting mechanical axis alignment.
• This approach is particularly useful for surgeons who infrequently perform OWHTO.
