PATELLAR LUXATION REGISTRY

----------------------------------------------------------------------------

Overview

1. Purposes - To identify those dogs that are phenotypically normal prior to use in a breeding program and to gather data on the genetic disease - patellar luxation.

2. Examination and Classification - Each dog is to be examined and classified by an attending veterinarian according to the enclosed application and general information instructions.

3. Certification - A certificate and breed registry number will be issued to all dogs found to be normal at 12 months of age or older. The OFA fee is $15.00 and no charge will be made for re-certification at a later age. The breed registry number will contain the age at evaluation and it is recommended that dogs be periodically re-examined as some luxations will not be evident until later in life.

4. Preliminary Evaluation - Evaluation of dogs under 12 months of age is encouraged if the owner desires to breed at this age. OFA will enter the information in a data bank at a fee of $10.00 for those found to be normal.

5. Dogs with Patellar Luxation - 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 patellar in the data bank.

Categories

Patellar luxations fall into several categories
1.) Medial luxation; toy, miniature, and large breeds.
2.) Lateral luxation; toy and miniature breeds.
3.) Lateral luxation; large and giant breeds.
4.) Luxation resulting from trauma; various breeds, and is of no importance to the certification process. Numbers 1, 2 and 3 are either known to be heritable or strongly suspected.
