Radiographic localization and isometry of the origin and insertion of the canine cranial cruciate ligament.

Objective: To radiographically define the anatomic origin and insertion of the cranial cruciate ligament translated to the lateral radiographic projection of the stifle (CrCL-Lo and CrCL-Li, respectively), to correlate these landmarks for identification of the CrCL-Lo intraoperatively, and to compare the isometry of the CrCL-Lo to the lateral fabella.

Study Design: Experimental study.

Sample Population: Pelvic limbs (n = 12) from dogs weighing 13-26 kg.
