🔍 Key Findings
- All four techniques achieved TPA <14°, meeting the threshold for acceptable surgical correction in eTPA cases.
- Group A (CBLO + CCWO) and Group D (PTNWO) showed highest accuracy in achieving target TPA values.
- Group B (TPLO + CCWO) resulted in significant tibial shortening compared to other techniques.
- Group A caused the greatest cranial mechanical axis shift, while Group B caused the least.
- Group C (mCCWO) resulted in consistent under-correction of TPA, despite aiming for 0°.
- Modified or neutral wedge osteotomies (Groups C and D) had minimal effect on tibial length, making them suitable when preservation is important.
- All techniques involved mechanical axis shifts, highlighting the importance of preoperative planning to minimize morphologic disruption.
- Supplemental fixation was standard for all procedures to reduce risks such as tibial tuberosity fracture and plateau leveling loss.
