What is Luxating Patella (Dislocating Kneecap)?

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 legSudden leg-lifting while walking that resolves on its ownReluctance to jump or climb stairsBow-legged or knock-kneed stanceCracking or popping sound from the kneeStiffness after rest

Diagnosis & Treatment

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.

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 for Luxating Patella (Dislocating Kneecap)

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.

Prevention Tips

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.

Expert Take: Insuring Against Luxating Patella (Dislocating Kneecap)

Luxating patella is the small-breed orthopedic condition I see most often, and it is heavily underwritten because it is hereditary. Yorkies, Pomeranians, Chihuahuas, French Bulldogs, Boston Terriers, Cavaliers, and Maltese are the highest-risk breeds, and surgical correction runs $1,500–$5,000 per knee — frequently bilateral, taking the total to $3,000–$10,000 across two surgeries.

For an orthopedic hereditary condition, the carrier choice is similar to hip dysplasia. Healthy Paws is my top pick — they cover hereditary conditions from day one of an active policy, no separate orthopedic wait, unlimited annual and lifetime payouts. Trupanion's per-condition lifetime deductible is the other strong play: meet it once for "luxating patella," and the second knee, all the rehab, and any post-surgical complications are covered at 90% for life. Avoid Embrace, Spot, ASPCA, and Pets Best unless you submit the orthopedic exam waiver at enrollment — that 6-month orthopedic wait at value carriers gets misapplied to bilateral claims constantly.

The pre-existing trap on luxating patella is particularly tricky because vets frequently grade it (Grade I–IV) at routine puppy visits, often as an incidental finding. Even a "Grade I luxation, asymptomatic" note at the spay/neuter visit will become permanent exclusion. Enroll small breeds — especially Yorkies and Pomeranians — at the very first vet visit, before the first orthopedic palpation. The cost reality: bilateral patella surgery plus rehab is $4,000–$8,000 out of pocket; with insurance and a $500 deductible at 90% reimbursement, you pay roughly $1,000–$1,500 total.
