Tibial Tuberosity Advancement (TTA)

Tibial Tuberosity Advancement (TTA) is an orthopedic procedure to repair deficient cranial cruciate ligaments in dogs. It has also been used in cats.

MMP uses a wedge-shaped implant of titanium OrthoFoam™ which both defines the degree of advancement of the tibial tuberosity and holds the bone in its new place while the bony ingrowth that provides permanent biomechanically robust fixation, develops.

The Modified Maquet Procedure (MMP) is so named to acknowledge the investigator of these operations – Dr P Maquet, a human orthopaedic surgeon working in Belgium during the 1960’s.

Designed as an evolution of Tibial Tuberosity Advancement (TTA), MMP has proven itself to be a much simpler & more cost-effective procedure that has excellent outcomes.

More than 75% of dogs will return to previous levels of unrestricted athletic activity and function.
