🔍 Key Findings
Population: 29 Boxer dogs and 29 age-matched Labrador Retrievers undergoing TPLO.
Scoring Systems Compared: 5-point vs. 10-point radiographic healing systems.
Healing Scores (Week 8):
- Boxers: 5-point mean = 3.3; 10-point mean = 6.9
- Labradors: 5-point mean = 3.6; 10-point mean = 7.5
- → Statistically significant difference (p = 0.0003 and p < 0.0001)
Osteotomy Gap ≥1 mm (present in 16.4%): Associated with significantly lower healing scores and increased recommendations for additional radiographic follow-up (p < 0.0001).
Observer Reliability:
- Both systems = good interobserver consistency.
- Slightly better intraobserver consistency with the 10-point scale.
Clinical Implication: Boxer dogs may need extended healing time or altered follow-up strategy after TPLO.
