Patellar Luxation in Havaneses
Orthopedic condition — Havanese — Small breed
High Risk
What is Patellar Luxation?
Patellar luxation occurs when the kneecap (patella) slips out of its normal groove in the femur. It is predominantly a condition of small and toy breeds and has a strong heritable component. Graded I–IV by severity; many dogs with Grade I–II are asymptomatic, while Grade III–IV causes significant lameness.
Symptoms of Patellar Luxation
- Intermittent skipping gait — holding up the affected leg for a few steps
- Audible clicking or popping from the knee
- Sudden leg lameness that resolves within a few steps
- Chronic lameness in severe cases
- Bowing of the hind legs
How Is Patellar Luxation Diagnosed?
Diagnosed by physical examination — the veterinarian manually displaces the patella and assesses ease of luxation and reduction. Grading I–IV indicates severity. X-rays evaluate bony conformation and rule out concurrent conditions.
Treatment & Cost
Grade I–II: medical management with weight control, exercise modification, and joint supplements. Grade III–IV or dogs with significant symptoms: surgical correction via groove-deepening procedures, tibial crest transposition, and/or soft tissue reconstruction. Success rates are high with surgery.
Most pet insurance plans cover patellar luxation treatment in full when the policy is active before diagnosis. Compare plans below.
