Luxating Patella (Dislocating Kneecap) — Pet Health Condition Guide by VETX.

Type: orthopedic | Species: dog

Treatment Cost: $1,500–$5,000 per knee

Prevalence: Affects approximately 7% of all puppies; up to 20% in small breeds

Overview

Luxating patella is a condition where the kneecap (patella) slides out of its normal groove in the femur, causing intermittent lameness and pain. It is one of the most common orthopedic conditions in small-breed dogs and is graded from 1 (mild, occasional luxation) to 4 (severe, permanent luxation). While Grade 1–2 cases may be managed conservatively, Grade 3–4 typically require surgical correction to prevent progressive joint damage and arthritis.

Symptoms

Intermittent skipping or hopping on one hind leg
Sudden leg-lifting while walking that resolves on its own
Reluctance to jump or climb stairs
Bow-legged or knock-kneed stance
Cracking or popping sound from the knee
Stiffness after rest

Diagnosis

Diagnosis is made through physical examination — the veterinarian can manually luxate and reduce the patella and assign a grade (1–4). X-rays assess the degree of bone deformity, groove depth, and secondary arthritic changes. Advanced imaging (CT) may be used for surgical planning in complex cases.

Treatment

Grade 1: monitoring and weight management. Grade 2: may benefit from surgery if causing frequent lameness. Grade 3–4: surgical correction is recommended. Surgical techniques include deepening the femoral groove (trochleoplasty), realigning the tibial crest (tibial tuberosity transposition), and tightening the joint capsule. Surgery costs $1,500–$5,000 per knee with a success rate of 90%+. Physical rehabilitation accelerates recovery.

Insurance Coverage

Luxating patella is covered by most pet insurance carriers as a hereditary/orthopedic condition. Some carriers impose 6–12 month waiting periods for orthopedic conditions. Healthy Paws covers luxating patella surgery after the standard 15-day waiting period. Given that bilateral luxation is common (affecting both knees), unlimited coverage is important.

Breeds at Risk

Yorkshire Terrier
Pomeranian
Chihuahua
French Bulldog
Boston Terrier
Cavalier King Charles Spaniel
Maltese
Pug

Prevention

Luxating patella is primarily genetic and cannot be prevented. Choose breeders who screen for orthopedic conditions. Maintain a healthy weight to reduce stress on the knee joints. Provide good traction on floors (rugs on hardwood) to prevent slipping. Regular, moderate exercise strengthens the muscles that support the knee. Avoid breeding affected dogs.

Frequently Asked Questions

Q: Does pet insurance cover luxating patella (dislocating kneecap) treatment?

A: Yes — luxating patella (dislocating kneecap) is covered by every major pet insurance carrier (Healthy Paws, Trupanion, Embrace, Spot, Lemonade, Pets Best, ASPCA, Figo) as a standard illness, provided it was not diagnosed or symptomatic before your policy's effective date and the waiting period has cleared. Luxating patella is covered by most pet insurance carriers as a hereditary/orthopedic condition. Some carriers impose 6–12 month waiting periods for orthopedic conditions.

Q: How much does luxating patella (dislocating kneecap) treatment cost without insurance?

A: Luxating Patella (Dislocating Kneecap) treatment typically costs $1,500–$5,000 per knee out of pocket without insurance. Surgical correction sits at the top of that range, while conservative management (weight control, anti-inflammatories, rehab) sits at the lower end. With pet insurance, you typically pay only the deductible plus 10–30% coinsurance after reimbursement.

Q: Is luxating patella (dislocating kneecap) considered a pre-existing condition?

A: Luxating Patella (Dislocating Kneecap) becomes a pre-existing condition — and is permanently excluded — if it was diagnosed, symptomatic, or treated before your policy's effective date or during the waiting period. Most carriers (Healthy Paws, Trupanion, Embrace, Spot, Pets Best, ASPCA) treat it as permanently pre-existing once documented in vet records. The single best protection is enrolling while your dog is healthy and asymptomatic — ideally as a puppy before any vet visits create a paper trail.

Q: Which pet insurance is best for luxating patella (dislocating kneecap)?

A: For luxating patella (dislocating kneecap), the strongest picks are Healthy Paws (unlimited annual and lifetime payouts — important when treatment runs $1,500–$5,000 per knee), Trupanion (per-condition lifetime deductible, so you pay it once for luxating patella (dislocating kneecap) and never again), and Embrace or Pets Best for value-tier capped plans. Avoid carriers with hard hereditary/orthopedic exclusions or unwaivable 12-month orthopedic waits.

Q: What breeds are most at risk for luxating patella (dislocating kneecap)?

A: Breeds at highest risk for luxating patella (dislocating kneecap) include Yorkshire Terrier, Pomeranian, Chihuahua, and others (Yorkshire Terrier, Pomeranian, Chihuahua, French Bulldog, Boston Terrier, Cavalier King Charles Spaniel, Maltese, Pug). Overall prevalence: affects approximately 7% of all puppies; up to 20% in small breeds. Because luxating patella (dislocating kneecap) has a strong hereditary component in these breeds, enrolling in pet insurance before any symptoms appear is essential — once diagnosed, it becomes a permanent pre-existing exclusion.

Q: Are there waiting periods for luxating patella (dislocating kneecap) coverage?

A: Most carriers apply a 14- to 15-day illness waiting period, but luxating patella (dislocating kneecap) as an orthopedic condition triggers an additional 6-month orthopedic waiting period at Embrace, Spot, ASPCA, and Pets Best. That orthopedic wait can usually be reduced to 14 days by submitting a vet-completed orthopedic exam waiver at enrollment. Healthy Paws and Trupanion have no separate orthopedic waiting period beyond their standard waits.
