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 Summary

• 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
