Patellar luxation is one of the most common orthopedic conditions in dogs. The patella, or “kneecap,” is normally located in a groove on the end of the femur, or thighbone. Patellar luxation (dislocation) is a condition where the knee cap rides outside the femoral groove when the knee is flexed.
The condition affects primarily small dogs, especially breeds such as Boston terrier, Yorkshire terrier, Chihuahua, Pomeranian, Bichon frise, and Miniature Poodle. The incidence in large breed dogs however has been on the rise over the past ten years
Dr. Geoffrey Hutchinson completed the 1st Kyon Patellar Groove Replacement (PGR) in Canada in October 2013 on a 5 year old Chihuahua patient named Bambi. PGR is a partial knee replacement surgery, a new method for treating patella luxation in all sizes of dogs. Some of the advantages of the PGR are that it reduces arthritic pain from chronic knee luxations and is available for dogs where conventional repairs have failed.
