Tibial tuberosity
advancement (TTA)
Developed in Switzerland in 2005, TTA has been
incorporated into mainstream veterinary practice
because it is less invasive than the TPLO procedure.
This surgery involves cutting through the tibial
tuberosity and advancing it forward. The strong and
thick patellar tendon passes through the kneecap and
inserts into the head of the tibia, where it then
bears tension and reduces the force generated by a
CCL rupture. By advancing the tibial tuberosity, it
reduces the angle of the slope and lengthens the
patellar tendon.
Since the surgery is less invasive, it requires a
smaller incision (7.5-12cm) [9], thereby reducing
anesthesia and shortening the operation time;
compared with TPLO, the patient can quickly bear
weight and there are fewer direct postoperative
complications. few. However, many studies conducted
over longer periods of time have shown similar
outcomes for each procedure.
Position requirements are similar to those for
contingent workers; x-rays and follow-up are
typically required during the 8th and possibly 12th
week of recovery. TTA surgery usually requires 10 to
12 weeks of recovery time. Within 24 hours after
surgery, the dog should be able to walk on its legs
and bear moderate weight within two weeks. At this
time, the dog can be taken to the toilet, and by the
eighth week, the dog can be taken for a 30-minute
walk twice a day. By 12 to 16 weeks, animals can
slowly increase to normal activity levels. However,
much depends on the protocols that individual clinics
have in place for their clients.
