    Total knee arthroplasty (TKA) is an effective treatment for advanced osteoarthritis, improving pain and function in patients.

  • 2

    The incidence of primary TKA is projected to increase by 143% by 2050, raising concerns about patient dissatisfaction and revision rates.

  • 3

    Revision TKA (rTKA) is expected to rise by 149% by 2040, with worse outcomes and higher costs compared to primary TKA.

  • 4

    Preoperative radiographic severity of osteoarthritis is a critical factor influencing outcomes and the risk of revision surgery.

  • 5

    The study aims to identify predictors for revision surgery within 10 years post-TKA, focusing on the Kellgren-Lawrence grading system.
