Area of Science:

  • Orthopedic surgery
  • Arthroplasty
  • Biomechanical engineering

Background:

  • High tibial osteotomy (HTO) is a common procedure for knee osteoarthritis.
  • Failed HTO necessitates revision surgery, often total knee arthroplasty (TKA).
  • TKA after HTO presents unique challenges compared to primary or other revision TKAs.

Purpose of the Study:

  • To review the literature on total knee arthroplasty following failed high tibial osteotomy.
  • To identify and discuss variables impacting outcomes in this specific patient subgroup.
  • To delineate preoperative and surgical technical factors relevant to TKA after HTO.

Main Methods:

  • Literature review of studies concerning TKA after failed HTO.
  • Analysis of clinical and radiographic factors influencing surgical outcomes.

  • Discussion of surgical techniques and potential complications.

    • Main Results:

    • TKA after failed HTO constitutes approximately 10% of knee replacements.
    • These cases are technically demanding, with difficulty in 20-40% of patients.
    • Outcomes are influenced by specific preoperative and intraoperative variables.

    Conclusions:

    • TKA after failed HTO is a significant subgroup requiring specialized consideration.
    • Careful preoperative assessment of clinical and radiographic factors is crucial.
    • Attention to surgical technical details is essential for successful outcomes in these complex revisions.
