Note. CrCL: cranial cruciate ligament; TPA: tibial plateau angle. Cranial tibial subluxation was measured using the method of [10]. CrCL length was measured using the method of [20]. Relative subluxation was calculated as a percentage of CrCL length. Dogs 5-12 were not available for long-term follow-up.
