• Median time to contralateral CCLR was 12.9 months.
• Older age reduced risk — 2% decrease per month of age (p=0.003).
• Golden Retrievers and Labradors had significantly lower risk (p=0.028 and p=0.007, respectively).
• No effect found from TPA, meniscal injury, or comorbidities (e.g., hip dysplasia, hypothyroidism).
