Luxating patella can be congenital or develop over time due to genetics and physical factors affecting the dog’s knee stability.
Understanding Luxating Patella in Dogs
Luxating patella is a common orthopedic condition in dogs where the kneecap (patella) slips out of its normal position. This displacement usually occurs laterally or medially, causing discomfort, lameness, or an abnormal gait. The question “Are Dogs Born With Luxating Patella?” often arises because this condition can appear early in a dog’s life, leading many to wonder if it’s something they inherit from birth or develop later.
The truth is, luxating patella has a strong genetic component. Many dogs are born with anatomical abnormalities that predispose them to this condition. The kneecap relies on a groove in the femur called the trochlear groove for stability. If this groove is shallow or malformed from birth, the patella has a higher chance of slipping out of place. However, other factors such as trauma, muscle weakness, or obesity can also contribute to its development over time.
Genetics and Congenital Factors Behind Luxating Patella
Most cases of luxating patella are linked to inherited traits. Breeds like Yorkshire Terriers, Pomeranians, Chihuahuas, and Poodles are notorious for having higher incidences of this condition. These breeds often have conformation issues with their knees right from birth.
Genetic predisposition means that puppies can be born with structural abnormalities such as:
- Shallow trochlear groove: This groove is too flat to hold the kneecap securely.
- Misaligned quadriceps muscles: These muscles pull the patella out of place.
- Abnormal bone structure: Femur or tibia malformations that affect knee alignment.
These congenital defects set the stage for luxation even before the puppy starts walking or running. So yes, many dogs are indeed born with luxating patella due to inherited traits affecting their knee anatomy.
The Role of Growth and Development
Even if a dog is genetically predisposed, luxation might not be immediately apparent at birth. As puppies grow rapidly during their first few months, any minor anatomical irregularities can become exaggerated under stress from increased activity levels.
The muscles and ligaments supporting the knee also develop during this time. Weakness or imbalance in these structures can allow the kneecap to slip more easily. Some dogs may show signs early on—like skipping steps or sudden lameness—while others might only reveal symptoms later as their joints wear down.
How Trauma and External Factors Influence Luxating Patella
While genetics play a central role in luxating patella’s origins, external factors can’t be ignored. Trauma such as falls or accidents can damage ligaments and tendons around the knee joint. This damage may destabilize the patella even if the dog wasn’t born with anatomical abnormalities.
Obesity is another significant contributor. Excess weight puts added pressure on joints and muscles, increasing strain on an already vulnerable knee structure. Over time, this stress can cause or worsen luxation symptoms.
Activity levels also matter. High-impact activities without proper conditioning may exacerbate joint instability in susceptible dogs.
Diagnosing Luxating Patella: Signs and Veterinary Assessment
Recognizing luxating patella early improves outcomes significantly. Owners should watch for signs such as:
- Intermittent skipping or “knuckling” of the hind leg.
- Limping after exercise.
- Sensitivity when touching around the knee.
- A noticeable clicking sound during movement.
Veterinarians perform physical exams by palpating the knee joint while flexing and extending it to detect abnormal movement of the patella. They grade luxation severity on a scale from I (mild) to IV (severe), which guides treatment decisions.
Radiographs (X-rays) help evaluate bone structure and rule out other joint diseases but don’t always show soft tissue issues clearly.
The Grading System Explained
| Grade | Description | Treatment Approach |
|---|---|---|
| I | Patella can be manually luxated but returns spontaneously. | Usually managed conservatively; monitoring and physical therapy. |
| II | Patella luxates frequently but returns to normal position. | Surgical correction considered if symptoms persist. |
| III | Patella remains luxated most times but can be manually repositioned. | Surgery typically recommended due to frequent discomfort. |
| IV | Patella permanently luxated; cannot be repositioned manually. | Surgical intervention necessary; risk of arthritis high. |
Treatment Options: Managing Congenital Luxating Patellas
Treatment depends heavily on severity and impact on quality of life. For mild cases (Grade I), conservative management often suffices:
- Weight control: Reducing strain on knees helps prevent worsening symptoms.
- Physical therapy: Strengthening surrounding muscles improves joint stability.
- Pain management: NSAIDs reduce inflammation if discomfort occurs.
More severe grades usually require surgery aimed at restoring proper alignment and stability of the kneecap. Common surgical techniques include:
- Trochleoplasty: Deepening the trochlear groove so the patella fits better.
- Tibial tuberosity transposition: Realigning attachment points of tendons controlling patellar movement.
- Lateral imbrication: Tightening tissues on one side of the joint to prevent slipping.
Postoperative care involves restricted activity followed by gradual physical rehabilitation for best results.
Surgical correction has a high success rate when performed by experienced veterinary surgeons—most dogs regain near-normal function afterward. However, complications like infection or recurrence do occur occasionally.
Long-term prognosis depends on how early treatment begins and whether arthritis has developed from chronic instability before surgery.
Because many dogs are born with structural abnormalities leading to luxation, early screening is crucial—especially for predisposed breeds. Detecting issues before severe damage occurs allows for less invasive treatment options and better outcomes overall.
Puppy wellness exams should include thorough orthopedic evaluations focusing on gait analysis and knee palpation tests by veterinarians familiar with breed-specific risks.
Owners noticing any irregular leg movements should seek veterinary advice promptly rather than waiting for obvious lameness signs.
Preventing congenital luxating patellas starts at breeding level too. Ethical breeders screen potential parent dogs through orthopedic exams and exclude those showing signs of knee instability from breeding programs.
This reduces passing on faulty genes responsible for shallow grooves or misaligned limbs that cause luxation problems down generations.
Breed clubs often recommend standardized screening protocols aimed at minimizing hereditary joint disorders like this one across susceptible breeds worldwide.
Limiting high-impact activities such as excessive jumping or running on hard surfaces helps protect fragile knees prone to slipping out of place prematurely.
Regular low-impact exercises like swimming build muscle tone without stressing joints harshly—a great option for dogs recovering post-surgery too!

Frequently Asked Questions
Are Dogs Born With Luxating Patella?
Yes, many dogs are born with luxating patella due to inherited structural abnormalities. Congenital factors like a shallow trochlear groove or misaligned muscles can predispose puppies to this condition from birth.
How Does Genetics Influence Luxating Patella in Dogs?
Genetics play a strong role in luxating patella. Certain breeds have inherited anatomical traits that increase the risk, such as malformed bones or muscle imbalances affecting knee stability.
Can Luxating Patella Develop After Birth in Dogs?
While many dogs are born with luxating patella, the condition can also develop over time. Factors like trauma, muscle weakness, or obesity may cause the kneecap to slip later in life.
What Signs Indicate Luxating Patella in Puppies?
Puppies with luxating patella may show early signs such as skipping steps, sudden lameness, or an abnormal gait. These symptoms often become noticeable as they grow and become more active.
Do All Dogs Born With Luxating Patella Show Symptoms Immediately?
No, not all dogs born with luxating patella exhibit symptoms right away. Some develop signs gradually as their muscles and ligaments grow and the stress on their knees increases during development.
