Diagnosing Patellar Luxation

Examination and Certification

The dog is examined awake (chemical restraint is not recommended) and classified by the attending veterinarian according to the application and general information instructions. The veterinarian then completes the application form indicating the the results of the dog's patella evaluation.

The application and fee can then be mailed to OFA. The attending veterinarian and owner is encouraged to submit all evaluations, whether normal or abnormal, for the purpose of completeness of data. There is no OFA fee for entering an abnormal evaluation of the patella in the data bank.

A breed database number will be issued to all dogs found to be normal at 12 months of age or older. The breed database number will contain the age at evaluation and it is recommended that dogs be periodically reexamined as some luxations will not be evident until later in life.

Preliminary Evaluations

Evaluation of dogs under 12 months of age is encouraged if the owner desires to breed at this age. The most opportune time to gather breeding data is at 6-8 weeks of age prior to the puppy's release to the new owner.
