Area of Science:

  • Orthopedic surgery
  • Biomedical engineering
  • Surgical technology

Background:

  • High tibial osteotomy (HTO) is a surgical procedure to correct knee osteoarthritis.
  • Traditional HTO techniques can have limitations in precision and may lead to sagittal plane abnormalities.
  • Patient-specific instrumentation (PSI) has emerged as a potential advancement in HTO.

Purpose of the Study:

  • To evaluate the role and effectiveness of patient-specific instrumentation (PSI) in high tibial osteotomy (HTO).
  • To assess the benefits of PSI in improving surgical precision, reducing complications, and streamlining operative efficiency.
  • To understand the advantages and limitations of PSI for informed clinical decision-making.

Main Methods:

  • Utilizing three-dimensional preoperative planning for multiplanar osteotomy templating.
  • Employing patient-specific cutting guides for precise bone cuts.
  • Using anatomically contoured implants designed for individual patient anatomy.

Main Results:

  • PSI enables precise restoration of the mechanical axis and facilitates complex biplanar corrections.
  • Patient-specific cutting guides and implants reduce intraoperative complications and improve surgical efficiency.
  • Early reports indicate high accuracy, safety, and effectiveness of PSI in HTO procedures.

Conclusions:

  • Patient-specific instrumentation (PSI) shows potential for improving outcomes in high tibial osteotomy (HTO).
  • PSI offers advantages in precision, safety, and efficiency compared to traditional methods.
  • Further long-term data is needed, but current evidence supports PSI as a valuable tool in osteotomy surgery.
