Understanding Luxating Patella

A luxating patella occurs when the kneecap moves out of its normal position. This can cause dogs to skip or run on three legs intermittently. It's common in small breeds like Maltese, Chihuahua, French Poodle, and Bichon Frise.

Causes and Symptoms

The kneecap may luxate due to misalignment, often seen in bowlegged dogs. Over time, this misalignment can worsen. Symptoms include skipping steps, running on three legs, and intermittent lameness.

Severity and Long-Term Effects

Luxating patella is graded from I to IV, with higher grades indicating more severity. The condition can lead to arthritis, decreased mobility, and joint pain, especially in higher grades. Both knees can be affected.

Treatment and Prognosis

Surgery is recommended for Grades II-IV and involves repositioning the patellar ligament, deepening the femur groove, and tightening the joint capsule. Early surgery offers an excellent prognosis. Post-operative care, including weight management and physiotherapy, is crucial for recovery.
