Luxating Patella
A condition where the kneecap (patella) slips out of its normal groove, causing intermittent lameness and pain, common in small breeds.
Detailed explanation
Patellar luxation occurs when the kneecap, or patella, dislocates from its normal position in the groove at the end of the thigh bone (femur). This can happen either towards the inside of the leg (medial luxation) or the outside (lateral luxation). It's most commonly seen in small breed dogs but can affect larger breeds and cats. Symptoms vary from occasional skips or limping to persistent lameness. The condition is graded from 1 (mild) to 4 (severe), based on how often and easily the patella dislocates. While mild cases might be managed conservatively, more severe or painful luxations often require surgery to deepen the groove or realign the bones, preventing further joint damage and pain.
Common symptoms
- Intermittent lameness or skipping steps
- Holding the affected leg up for a few steps
- Reluctance to jump or bear weight
- Pain (especially in higher grades)
