Summary
Tibial tuberosity advancement (TTA) is a viable surgical option for dogs with cranial cruciate ligament disease, showing good outcomes and owner satisfaction despite some minor complications.
Area of Science:
- Veterinary Surgery
- Orthopedics
- Canine Sports Medicine
Background:
- Cranial cruciate ligament (CCL) disease is a common cause of lameness in dogs.
- Tibial tuberosity advancement (TTA) is a surgical technique developed to address CCL deficiency.
- Understanding TTA outcomes is crucial for veterinary orthopedic surgeons.
Purpose of the Study:
- To evaluate the clinical and radiographic outcomes of the tibial tuberosity advancement (TTA) procedure in dogs with cranial cruciate ligament deficient stifles.
- To assess the complication rates and owner satisfaction following TTA surgery.
- To analyze changes in the patellar ligament-tibial plateau angle and degenerative joint disease progression post-TTA.
Main Methods:
- Retrospective descriptive study of 57 dogs undergoing unilateral or bilateral TTA.
- Review of medical records and radiographic assessments (preoperative, postoperative, follow-up).
- Owner questionnaires assessing procedural outcome, complications, and activity level.
Main Results:
- Sixty-five stifles in 57 dogs were treated with TTA.
- Mean age 5.2 years, mean weight 39.7 kg; Labrador retrievers and mixed breeds predominated.
- 59% of cases had complications (mostly minor); major complications were uncommon.
- Preoperative alpha angle averaged 100°, postoperative 95.5°.
- 67% showed radiographic progression of osteoarthritis.
- 90% of owners reported good to excellent outcomes; 90% noted improved activity levels.
Conclusions:
- Tibial tuberosity advancement (TTA) appears to be a useful alternative for managing canine cranial cruciate ligament disease.
- The procedure is associated with good clinical outcomes and high owner satisfaction.
- Severe complications are infrequent, making TTA a favorable surgical option.

01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
