Patellar Luxation in Dogs: 3 Myths to Leave Behind
Myth 1: Patellar luxation is diagnosed under sedation.
No. Patellar luxation is a clinical diagnosis that should be made in the conscious patient. Sedation relaxes the muscles and can significantly alter patellar stability.
Myth 2: X-rays diagnose patellar luxation.
No. The diagnosis is made during the orthopaedic examination. Radiographs are used to assess bone morphology and limb alignment, helping guide surgical planning.
Myth 3: Physiotherapy alone will fix the problem. Physiotherapy can improve strength and function, but patellar luxation is fundamentally a mechanical disorder. Rehabilitation cannot correct the underlying anatomical abnormalities causing the luxation.

Patellar luxation is more than an occasional skipping gaitāit is a condition that can lead to progressive joint degeneration.
