| Abstract: | Excessive mechanical stress due to caudal sloping of the tibial plateau may result in early breakdown of the cranial cruciate ligament (CrCL). Five dogs with CrCL rupture associated with caudal sloping of the proximal tibial plateau are described. All were small dogs, of between three and six years of age, with a mean bodyweight of 9.3 kg, which had acute hindlimb lameness. Radiographic examination revealed cranial displacement of the tibia, with a tibial angle varying from 58 to 60 degrees. All cases were treated with a lateral fabellotibial suture and cranial cuneiform osteotomy of the proximal tibia. All dogs were using the operated limb three days after surgery, with normal gait re-established after a mean period of 10 days. Excessive tibial plateau sloping is not a frequent cause of hindlimb lameness in small animals, although it is important to consider it as a predisposing factor for rupture of the CrCL. |
