Dr. Chad Aderhold, a 1990 Georgia graduate, has performed more than 250 Tibial Tuberosity Advancement (TTA) surgeries. In addition to performing surgeries at our Wilkes location, he also travels to other area hospitals to perform orthopedic surgeries. He attends conferences and educational opportunities to get the most up-to-date training.
The TTA surgery corrects the most common knee injury in dogs, the rupture or partial tear of the cranial cruciate ligament. This injury can occur in any age or breed of dog, but tends to occur in overweight, middle-aged dogs. A partial tear untreated most commonly leads to a rupture. Most owners notice a limp or unstability of the knee. Untreated knees are very painful and become arthritic. The only treatment for these types of injuries is surgery. The TTA procedure is less envasive and more economical than other orthopedic procedures to repair these ligaments.
The TTA procedure involves making a cut in the front part (tibial tuberosity) of the tibia or shin bone and advancing this portion of the bone forward and slightly upward in order to realign the patellar ligament. This eliminates abnormal sliding movement with-in the knee. A specialized bone spacer,plate, and screws are used to secure the bone in place. A bone graft is collected from the top of the tibia and placed in the gap below the spacer. The graft stimulates healing.
After surgery care is minimal for most patients. Surprisingly most patients bear weight on the leg the next day following surgery. Immediately following surgery activity is restricted to short leash walking and cage rest. Dr. Aderhold feels most patients are healed in 16 weeks.
If your dog is experiencing any of these symptoms, call for a consultation with Dr. Aderhold!
