A luxating patella is a knee cap that slips out of its normal groove. It's especially common in small breed dogs, though larger dogs and cats can have it too. Some pets are born with it, while others develop it after an injury.
Many pets with a mild luxating patella skip or hop for a few steps, then go back to walking normally once the knee cap slips back into place. Over time, though, the condition can cause pain, arthritis and other knee injuries, so it's important to have it checked.
Signs of a Luxating Patella
Signs can come and go, and many owners first notice an odd skip in their pet's step. Watch for:
- Skipping or hopping on a back leg for a few steps
- Holding a back leg up, then suddenly using it again
- Kicking a back leg out to the side
- Limping or stiffness in the back legs
- Bow-legged or knock-kneed posture
Your vet will feel the knee to check how easily the knee cap moves out of place and may recommend X-rays to look at the joint.
Treatment Options and Recovery
Luxating patellas are graded by how severe they are. Mild cases may be managed with weight control, exercise changes, joint supplements and pain relief when needed. More severe cases, or pets with ongoing pain or lameness, may need surgery to help keep the knee cap in its groove.
After surgery, most pets need several weeks of restricted activity with short leash walks, followed by a slow return to normal exercise. Your vet will guide you through each step of recovery.
