Cranial Cruciate Ligament Rupture
A ruptured cranial cruciate ligament (known as anterior cruciate ligament “ACL” in humans) is
one of the most common orthopedic diseases of our pets. Due to the angle of the stifle (knee) joint in the canine and feline, there is tremendous force placed on the cranial cruciate ligament, causing it to fatigue and eventually breakdown. When this happens, instability is created, allowing a forward thrusting motion of the tibia (tibial thrust) with respect to the femur. The tibial thrust causes pain and can damage other tissues within the joint, mainly the meniscus (padding between the femur and tibia). If left untreated, arthritis will form, which can lead to chronic pain and lameness. Avon Lake Animal Clinic offers surgical correction of the ruptured cranial cruciate ligament. Although multiple procedures are available for correction of the deficient cruciate ligament, we have concentrated on the three that we feel give the best results. For our small patients, usually less than 20 pounds, we recommend a lateral stabilization method. For our larger patients, a Tibial Tuberosity Advancement (TTA or TPLO) is preferred. Our veterinarians, through a comprehensive orthopedic examination, will make medical recommendations as to what is best for your pet. If you have any questions about cranial cruciate disease, please contact one of our veterinarians, and we would be happy to discuss your options.
