🔍 Key Findings
- Study population: 116 dogs underwent cementless THR; grouped by age:
- Group A: ≤6 months (n = 27)
- Group B: >6 to ≤12 months (n = 41)
- Group C: >12 months (n = 48)
- Overall perioperative complication rate: 31.9% (37/116)
- Group A: 22.2%
- Group B: 26.8%
- Group C: 41.7%
- No significant difference in total complication rate by age (p = .207), though older dogs (Group C) had numerically higher rates.
- Luxation was significantly more common in dogs >12 months:
- Group C: 14.6% vs. Group A (0%) and Group B (2.4%) → p = .049
- Most common complications: luxation (9.5%) and intraoperative fissure or fracture (9.5%)
- Time under anesthesia and surgery duration were not associated with complication risk (p = .297 and p = .781)
- No infections or aseptic loosening observed during the 8-week follow-up.
