Patella Luxation Surgical Repair

Luxation is a condition where the patella (kneecap) rides outside its groove.

Pertinent Anatomy

The patella is a small bone that sits within a groove of the thigh bone (femur) at the level of the knee. The patella is connected to the shin bone (tibia) through the patellar ligament and the quadriceps muscle of the thigh bone works through the patella and patellar ligament to extend the shin bone. This forms the “extensor mechanism” and all components are well-aligned in normal pets.

Clinical Signs

Clinical signs are dependent on the severity of the disease and may be found incidentally in some patients.

Success Rate

Success is defined as an improvement in patellar luxation classification severity and return to function.

Owner satisfaction of pet’s mobility after surgery is favorable.

Surgery Process

The goal of surgery is to provide a deep groove for the patella to sit in and align the quadriceps, patella, and shin bone for pain-free movement. This is done through a combination of procedures that are unique to each patient and patellar luxation classification.

Bone Procedures:
  • Trochlear Wedge Recession (groove deepening)
  • Tibial Tuberosity Transposition (moving the attachment of the patellar ligament)
Soft Tissue Procedures:
  • Fascial Release
  • Facial tightening

Complications

Recovery

Recovery will vary depending on severity of previous patellar luxation and procedures performed. An 8 week recovery is most often advised.
