The detail information of Patella luxation
Basic Information

Disease Description: A condition where the knee caps slide in and out of place.

Inherit Mode: The mode of inheritance is not yet known. Some researchers think that this disease may be polygenic.

Disease Symptom: When present, thecondition is usually evident in young dogs byaround 6 months of age, but if mild it may go unnoticed until the dogis older. When theknee cap is out of place, your dog will be lame and may refuse to bearweight, or his/her knee may be "locked". The severity of the condition varies widely. Inmildcases, the knee cap may only slip out of place occasionally, causingyour dog to"hop" for a few steps, and then it may slide back into the groove onits own. Insevere cases, the knee cap slips out of place more often, or is neverin a normalposition. It may not go back into the groove on its own and yourveterinarian may need topush it back into place. As a result of patellar luxation, your dog maydevelop otherdegenerative joint changes, such as osteoarthritis. If your dog has amild case of thisdisease, you may not notice the actual luxation, but your dog mayeventually develop paindue to osteoarthritis.

Disease Cause: -

Disease Diagnose: Your veterinarian will diagnose this disease based onphysicalexamination and palpation. He/she may take radiographs to see if yourdog has otherproblems (such as osteoarthritis) as a result of this disease.

Treat Method: The treatment and long term outcome (prognosis)depend on theseverity of disease (how often the knee cap slips out of place, andhow easily it slipsback into the normal position), and whether there are other problemssuch asosteoarthritis. Moderate or severe cases often require surgery to makesure that the kneecap stays in the groove in the femur, and to prevent painfulosteoarthritis. Exerciserestriction is important for a period after surgery, and the resultsare usually verygood.

Breeder Advice: Affected dogs, as well as their parents, theirlitter-mates, and anydog which has had surgery for patellar luxation, should not be bred.The OrthopedicFoundation of America - www.offa.org -and Institute for Genetic Disease Control in Animals - www.vetmed.ucdavis.edu/gdc/gdc.html - have registries for this condition.
