Anatomy of the Cranial Cruciate Ligament
The cranial cruciate ligament, or CCL, in canines is analogous to anterior cruciate ligament, or ACL, in humans. The CCL is the main supporting ligament within a dog’s knee, or stifle. This ligament bears the weight of a majority of the stifle’s load, which is why instability of the CCL results in lameness, arthritis and other degenerative changes of the knee joint and surrounding tissue. The strength of this ligament will decrease as a dog ages, with larger dogs experiencing an increased rate of degeneration versus smaller breed dogs. Obese dogs are at a higher risk for CCL rupture as obesity places additional stress on the ligament. Ruptures of the cranial cruciate are the most common orthopedic injury for dogs and the leading cause for arthritic tissue in the stifle. Read the rest of this entry »
