Have you ever noticed your dog suddenly lift a back leg, skip a few steps, and then walk normally again? This can be a sign of patellar luxation, a condition where the kneecap slips out of its normal position. Some dogs experience only occasional symptoms, while others develop ongoing discomfort or difficulty walking.
At Stonebridge Veterinary Wellness, our veterinarians can examine your dog’s knees, assess the severity of the condition, and help you understand the treatment options. Not every dog needs surgery, but when orthopedic surgery is recommended, we’ll explain why and what to expect.
Why Does a Dog’s Kneecap Slip Out of Place?
The kneecap, also called the patella, normally moves within a groove at the end of the thigh bone as your dog bends and straightens their leg. If the groove is too shallow or the surrounding bones and muscles aren’t properly aligned, the kneecap can slip out of place. The condition is more common in smaller breeds, although larger dogs can develop it too. It can also result from an injury.
Symptoms range from an occasional skip to frequent limping or difficulty using the affected leg. Mild cases may cause little discomfort, but symptoms can become more noticeable over time. Some dogs show no obvious signs at home, so patellar luxation may first be detected during a routine annual checkup. Because the condition can affect both knees, our veterinarians examine each leg.
How We Evaluate the Knee
Evaluation begins with a hands-on orthopedic exam. Our veterinarians gently move your dog’s knee to see how easily the kneecap slips out of place and whether it returns to its normal position on its own. X-rays help us assess the knee joint and surrounding bones, and sedation may be recommended to keep your dog comfortable and obtain clearer images. If surgery is being considered, bloodwork and other pre-surgical screenings help us evaluate your dog’s overall health before anesthesia.
Results are described in four grades, from an occasional slip to a kneecap that stays out of place. The American College of Veterinary Surgeons notes that surgery is most often considered at grade 2 or higher, though your dog’s age, size, and lifestyle shape the final recommendation.
Signs That Surgery May Be Worth Discussing
A kneecap that slips without causing trouble is often watched rather than operated on. Surgery becomes part of the conversation when the problem starts to affect comfort or movement. Common signals include:
- Frequent skipping: The leg lifts more often or stays up longer
- Ongoing lameness: Limping that does not settle with rest
- Visible pain: Reluctance to jump, play, or put weight on the leg
- Higher grades: A kneecap that stays out of place for longer stretches
- Knee strain: Signs of related joint stress, such as a ligament injury
Repeated slipping can wear down joint cartilage, causing inflammation and arthritis, and strain the rest of the knee, including the cranial cruciate ligament. Addressing the problem early may limit further cartilage wear, and our doctors can also check for related issues, including the need for ligament repair.
What Patella Luxation Surgery Can Involve
Patella luxation surgery focuses on helping the kneecap stay in its proper position. Depending on your dog’s condition, the surgeon may deepen the groove in the thigh bone where the kneecap normally sits or adjust the surrounding tissues to improve alignment. The exact approach depends on the structure of your dog’s knee, and some decisions may be made during surgery after the joint has been examined more closely.
Our veterinary team, including board-certified surgeon Dr. Erin Paster, evaluates each dog’s condition to determine the appropriate surgical approach. Throughout the procedure, our anesthesia team monitors your dog’s vital signs and uses warming devices and heated blankets to help maintain their body temperature during surgery and recovery.
Patella Luxation Recovery and Home Care
After patella luxation surgery, your dog will likely need time to heal before returning to normal activities. Recovery typically involves several weeks of restricted movement, followed by a gradual increase in activity based on our surgeon’s recommendations. We’ll explain what to expect at each stage and develop a pain management plan with guidance from a veterinarian certified in pain management.
At home, you’ll need to prevent running, jumping, and unnecessary stair climbing while your dog’s knee heals. Follow-up appointments allow our veterinarians to check their progress and let you know when it’s safe to increase activity. Before surgery, we’ll also discuss the expected recovery timeline, costs, and potential outcomes so you can prepare for your dog’s care at home.
