| Abstract: | The clinical, radiographic, arthroscopic and pathological findings of 10 horses with injury to the cranial cruciate ligament are presented. The most consistent clinical signs included moderate to severe distension of the femoropatellar joint and a Grade III to a Grade V out of V lameness. Craniocaudal instability could be elicited in five horses under general anaesthesia and in one conscious horse. Radiographic evaluation of the stifles revealed that avulsion fracture of the medial intercondylar eminence was the most common finding in six out of 10 horses. Arthroscopic examination of the affected femorotibial joints were performed in five horses. This confirmed the presumptive diagnosis of cranial cruciate ligament injury or rupture. Post mortem examinations were performed on two horses which documented partial tears of the cranial cruciate ligament. |
