When it comes to treating cranial cruciate ligament (CCL) injuries in dogs, two prominent surgical techniques have gained recognition in recent years: TTA and TPLO. In 2022, these two methods continue to be at the forefront of veterinary orthopedics, offering improved outcomes and long-term stability for our four-legged companions. This article aims to provide an in-depth comparative analysis of TTA vs TPLO in 2022, shedding light on the nuances, advancements, and considerations associated with each technique.

What is TTA?

TTA, or Tibial Tuberosity Advancement, is a surgical technique developed to address CCL injuries in dogs. This procedure involves the advancement of the tibial tuberosity, altering the forces acting on the CCL and stabilizing the joint. By repositioning the tuberosity, TTA aims to promote natural healing and provide long-term stability.

What is TPLO?

TPLO, or Tibial Plateau Leveling Osteotomy, is another surgical option for CCL repair. TPLO involves cutting and repositioning the tibial plateau to modify the biomechanics of the knee joint. This procedure aims to eliminate the need for a functional CCL, allowing the joint to stabilize without relying on the ligament.

Comparative Analysis of TTA vs TPLO in 2022

Both TTA and TPLO have shown positive outcomes in terms of restoring joint stability and improving the quality of life for dogs with CCL injuries. However, there are several key differences between the two techniques that warrant consideration.

Surgical Approach

TTA involves creating an osteotomy in the tibial tuberosity, advancing it, and stabilizing it with a bone plate. On the other hand, TPLO requires an osteotomy in the tibial plateau, which is then rotated and secured with a bone plate. The surgical approach and specific modifications to the bone differ significantly between TTA and TPLO.

Biomechanical Effects

TTA alters the angle of the patellar tendon, effectively reducing the tibial plateau angle, and consequently, the shear forces acting on the CCL. TPLO, on the other hand, levels the tibial plateau, eliminating the need for an intact CCL by changing the joint mechanics. These differing biomechanical effects contribute to the distinct approaches and long-term outcomes of each technique.

Postoperative Rehabilitation

Recovery and rehabilitation protocols are crucial for the success of both TTA and TPLO surgeries. Postoperative care may include restricted activity, physical therapy, and pain management. The duration and intensity of the rehabilitation process may vary between the two techniques, and it is essential for pet owners to follow the veterinarian's guidance for optimal healing.


In 2022, TTA and TPLO remain viable options for repairing CCL injuries in dogs, with each technique presenting its own advantages and considerations. TTA offers the benefits of a simpler surgical approach and postoperative care, while TPLO provides biomechanical changes that can eliminate the reliance on a functional CCL. Ultimately, the choice between TTA and TPLO should be made in consultation with a veterinary professional who can assess the individual patient's needs and recommend the most appropriate treatment plan.

Remember, when considering TTA vs TPLO in 2022, it is crucial to evaluate the dog's size, breed, activity level, and overall health, as well as the surgeon's expertise. With advances in veterinary orthopedics, both TTA and TPLO techniques continue to evolve, providing effective solutions for dogs suffering from CCL injuries, restoring their mobility, and enhancing their quality of life.
