When the cranial cruciate ligament is torn, the knee joint slides forward painfully whenever the animal walks. Shifting the front piece of the shin bone (the tibial tuberosity) forward alters the dynamic pull angle of the primary patellar tendon. By reorienting this tendon to a perpendicular 90-degree angle relative to the joint surface, the large quadriceps muscle group naturally stabilizes the joint and stops the sliding motion without requiring a replacement ligament.

Traditional TTA relies on an arrangement of long titanium cages, plates, and retaining forks secured with multiple screws to hold the bone forward. MMP streamlines this dynamic by using a porous, wedge-shaped titanium implant made of advanced metallic foam. This wedge defines the required advancement space and physically holds the bone structure in place with minimal hardware components.

Porous structures mimic the natural framework of biological bone tissue. When placed in the osteotomy gap, the microscopic channels allow adjacent blood vessels and bone cells to migrate directly into the material. Over several weeks, new bone structure grows entirely through the implant, creating an interconnected biological and mechanical fusion that is incredibly strong and permanent.

Yes, while cranial cruciate ligament degeneration is far more common in dogs, cats can also experience complete or partial ligament ruptures due to physical trauma, climbing accidents, or obesity strains. The mechanical principles of advancing the tibial tuberosity translate safely to feline anatomy, allowing for joint stabilization once the bone structures heal.
