Tibial Tuberosity Advancement (T.T.A)

The most common knee injury in canines is rupture of the cranial cruciate ligament (CCL), also referred to as the Anterior Cruciate Ligament (ACL). This injury can occur at any age and in any breed, but most frequently occurs in middle aged, overweight dogs. This ligament frequently can suffer a partial tear, leading to slight instability of the knee. If this damage goes untreated, it most commonly leads to complete rupture and possibly damage to the medial meniscus of the knee. The meniscus acts as a cushion in the knee. In about 50 % of the dogs with ACL injuries, the meniscal cartilage has been injured as well. This type of injury is often accompanied by a “click” that can be heard when a dog walks. Complete rupture of the ACL results in Tibial Thrust (front & back instability), Pivot Shift (internal rotation of the lower leg), and severe pain for your pet. If injury is left untreated, your pet will become very arthritic and painful from the instability.

An injured ACL can only be corrected by surgery. There are numerous surgical corrections that can be performed. Dr.Pearce performs all orthopedic procedures including: (1) T.T.A – Tibial Tuberosity Advancement, (2) TPLO – Tibial Plateau Leveling Operation, and (3) E.C – External Capsular Repair.

This page will focus on the T.T.A, Dr. Pearce’s favorite procedure to repair a ruptured ACL. The T.T.A is one of the newest procedures and in his opinion the BEST repair for most dogs, in that rehabilitation time and expense is seldom needed or compared to older procedures. The T.T.A procedure allows a more rapid recovery in most dogs and is less invasive than the other procedures. Dr. Pearce has performed over 160 T.T.A surgeries since 2008.
