An 11.4-kg female llama that had been born without assistance while its dam was under observation at the veterinary teaching hospital was observed to ambulate abnormally on its right hind limb. A cranial drawer sign could be elicited in the right stifle. Cranial displacement of the tibia relative to the femur and dysplasia of the proximal end of the tibia were seen on radiographs. When the cria was 10 days old, the joint was stabilized with a fascia lata autograft. At the time of surgery, a segment of thin, loose tissue was found where the cranial cruciate ligament would have been. Three years after surgery, the llama gave birth to a normal cria and was 60 days pregnant with a second cria. To our knowledge, congenital cranial cruciate ligament deficiency with tibial dysplasia has not been reported in llamas. The heritability of these defects is unknown.
