One of the most common knee problems in dogs is the Cranial Cruciate Ligament, which is sometimes referred to as the ACL. It can occur at virtually any age in the dog’s life, and in any breed. Sometimes this ligament can have a partial tear which can give the dog instable knees. Untreated tears or damage can lead to a complete rupture, which can further damage the medial meniscus. The medial meniscus pads the dog’s knee. If a full rupture happens, the dog can become instable from the front legs and back legs. When these injuries occur, it can lead to arthritis and become painful for the dog from the constant instability.
An injured cruciate requires surgery. There are several correctional procedures being performed. The first is a External Capsular Repair, the second a TightRope Procedure, the third a Tibial Plateau Laveling Operation and lastly the Tibial Tuberosity Advancement – otherwise known as TTA.
