Surgery costs $1,500-$3,000 per knee - many cats need both knees fixed. The kneecap slides out of its groove, graded I-IV. Without treatment, the joint wears down and arthritis develops early.
What Causes Luxating Patella in Cats
The kneecap slides out of its groove in the femur - usually a congenital defect. Graded I-IV: Grade I pops back on its own; Grade II slips during movement; Grade III stays dislocated; Grade IV is permanent. Most cats diagnosed at Grade II or III.
Symptoms What to Watch For
Skipping or hopping on a back leg. Reluctance to jump. Stiffness after resting. Crouching walk. Advanced cases show persistent lameness and muscle loss. The "bunny hop" gait is telltale, but many cats compensate well - early signs are easy to miss.
Diagnosis $150-$400
Treatment $1,500-$3,000/knee
Grade I: monitoring. Grades II-IV: surgery to deepen the femoral groove - $1,500-$3,000 per knee. Conservative management with pain meds and supplements ($30-$80/month) for non-surgical candidates. Weight management critical for all grades.
Total Cost $1,800-$6,500
Diagnosis plus surgery for one or both knees, including post-op care. Bilateral cases double the surgery cost. $1,800-$6,500 depending on grade and number of knees.
Certain Breeds Higher Risk
Devon Rex, Abyssinian, Siamese, and Bengal cats are predisposed. Smaller and lighter-boned breeds are more commonly affected. Any cat can develop it, but genetics play a major role.
Recovery 6-8 Weeks
Strict cage rest for 4-6 weeks after surgery. Gradual return to normal activity over 6-8 weeks. Success rate is 90%+ for surgical correction. Physical therapy can speed recovery.
Prevention
Keep your cat at a healthy weight to reduce joint stress. Avoid breeding affected cats. Early diagnosis prevents arthritis from developing in the damaged joint.

Insurance Traps
Surgery costs $1,500-$3,000 per knee. Insurance can cover most of it - if you enroll early enough.
Luxating Patella Coverage Basics Pre-existing
Most policies cover surgery if enrolled before symptoms appear. A 14-day illness waiting period applies, plus many have a 6-12 month orthopedic waiting period. Diagnosis, surgery, anesthesia, post-op meds, and follow-ups typically covered.
The Orthopedic Waiting Period Trap Waiting period
Many insurers impose a 6-12 month orthopedic waiting period. Symptoms during this window become pre-existing and won't be covered. Some plans waive this with a vet exam within 14 days of enrollment. Read the fine print.
Bilateral Coverage Issues Bilateral
Both knees may count as one condition - one deductible applies, which helps. But some plans cap per-incident payouts. Bilateral surgery exceeds $6,000 - check your plan's per-condition limits.
Congenital vs Hereditary Exclusions Exclusion
Budget policies often exclude congenital and hereditary conditions. Premium plans cover them. For Devon Rex, Abyssinian, or predisposed breeds, verify your policy covers hereditary orthopedic conditions.
Common Questions
Real answers about costs, treatment, and insurance coverage.
What is a luxating patella in cats?
The kneecap slips out of its groove in the thigh bone, graded I-IV. Grade I slips occasionally; Grade IV is permanent. Most diagnosed at Grade II or III. Usually congenital - shallow groove or misaligned leg - though trauma can cause it.
How much does luxating patella surgery cost for a cat?
Surgery costs $1,500-$3,000 per knee. Bilateral: $3,000-$6,000 total, sometimes discounted. Add $150-$400 for diagnosis and $200-$500 for post-op meds and follow-ups.
Can a cat live with a luxating patella without surgery?
Grade I cats often live comfortably without surgery. Grade II can sometimes be managed with weight control, supplements, and pain meds. Grades III and IV typically need surgery. Without correction, painful arthritis develops early.
What are the signs of luxating patella in cats?
Skipping or hopping on a back leg. Bunny-hop gait, reluctance to jump, stiffness after resting, crouching walk. Advanced cases show lameness and muscle loss. Many cats compensate - early signs are easy to miss.
How long is recovery after luxating patella surgery?
Strict rest 4-6 weeks, then gradual return over 2-4 weeks. Full function within 2-3 months. Success rate exceeds 90%. Physical therapy speeds recovery.
Is luxating patella hereditary in cats?
Yes - congenital and hereditary in most cases. Devon Rex, Abyssinian, Siamese, and Bengal are predisposed, though mixed breeds affected too. Responsible breeders screen and avoid breeding affected cats.
Can luxating patella affect both knees?
Yes - about 50% have it in both. Evaluate both at diagnosis even if only one is symptomatic. Bilateral surgery: $3,000-$6,000 total, best long-term outcome.
Does pet insurance cover luxating patella surgery?
Most comprehensive policies cover surgery if enrolled before symptoms appear. Many impose 6-12 month orthopedic waiting periods. At $1,500-$3,000 per knee, insurance is worthwhile. Ensure coverage for hereditary conditions for predisposed breeds.
My mother-in-law's boxer. Problem. $1,200 in tests, no answers. Another vet solved it with $8 pills. When you're scared, you'll pay anything - and some vets price accordingly. So I built what I couldn't find: real costs, real exclusions, plain language. Not selling policies.
