Moreira et al: Predicting tibial plateau angles following four different types of cranial closing wedge osteotomy using patient-specific 3-dimensional computer models
Veterinary Surgery 1, 2024

🔍 Key Findings

  • Study Type: In silico 3D modeling of canine tibiae (n = 20 limbs)
  • Four techniques evaluated:
    1. Proximal-centered wedge
    2. Middle-centered wedge
    3. Distal-centered wedge
    4. Slocum-type wedge (based on tibial plateau and cranial cortex)
  • Target TPA: 5°
  • Most accurate: Slocum technique had the smallest mean prediction error (mean = –0.7°, SD = 0.5°)
  • Least accurate: Proximal-centered wedge (mean error = –2.9°, SD = 1.2°)
  • Error variation: Prediction error increased with greater initial TPA; high correlation (R² = 0.74)
  • Conclusion: Planning based on tibial plateau and cranial cortex (Slocum method) yields better TPA predictability
