The first step with a pet with a possible luxating patella would be an examination with a veterinarian that has experience with luxating patellas and the associated surgery. This would cost around $55. X-rays might be recommended afterward. The cost of the X-rays with sedation would be $200-300. Should surgery be needed, the cost would be an additional $1500-2000.
