Overview

Randomized trial compares implant survivorship and outcomes in TKA patients after HTO, indicating no adverse effects.

Key Points

  • This research aims to compare the long-term outcomes of total knee arthroplasty (TKA) after high tibial osteotomy (HTO) with TKA-only patients.
  • Study included 134 patients who had TKA after HTO and 268 matched TKA-only controls, following them from 2000 to 2023.
  • Knee Society Scores were used to assess outcomes, and data were analyzed using Kaplan-Meier curves and Cox models.
  • Patients were matched based on age, sex, and body mass index.
  • Both groups had significant improvements in Knee Society Scores, with scores showing no notable difference (HTO-TKA: 79.0, TKA-only: 79.0).
  • Revision rates were 5.2% for HTO-TKA compared to 4.5% for TKA-only (p = 0.69).
  • Infection rates were 2.2% for HTO-TKA and 1.1% for TKA-only (p = 0.74).
