Tibial Plateau Leveling Osteotomy Plate Design Influences Interfragmentary Compression: An In Vitro Study
🔍 Key Findings
- Biocurve TPLO plate generated the highest and most uniform interfragmentary compression, particularly in the cranial quadrants (Q1: 0.285 MPa; Q2: 0.304 MPa), due to its opposing angled dynamic compression holes.
- Synthes TPLO plate produced the lowest compression across all quadrants (0.050–0.111 MPa), remaining within the low compression range.
- Arthrex plate achieved intermediate compression, with high compression in the craniolateral quadrant (Q2: 0.292 MPa) but only moderate compression elsewhere.
- Plate design significantly affected compression distribution (p < 0.001), confirming that screw hole orientation and plate geometry influence osteotomy compression patterns.
- Cranial compression (Q1–Q2) was greatest with the Biocurve plate, potentially improving stability against “rock-back” or loss of tibial plateau angle.
- No significant differences between plates were found in caudal quadrants (Q3–Q4), suggesting plate design primarily affects cranial compression.
- Pressure-sensitive film analysis allowed quantitative mapping of compression patterns, dividing the osteotomy interface into four quadrants for standardized comparison.
- Clinical superiority of one plate was not concluded, but findings suggest plate geometry and dynamic compression hole orientation influence mechanical stability during TPLO fixation.
