Luxating Patella is an orthopedic condition describing the knee cap dislocating (popping out of joint or luxating). Disclocated kneecaps cause condition so painful pets often refuse to use the affected leg and carry it high, running on three legs.
The recommended remedy is reparative surgery. The surgical repair involves deepening the groove in which the patella normally slides, as well as plicating (folding) the stifle (knee) joint capsule to give the patella more restraint and stability. Weight loss, exercise restriction and antibiotics are indicated post operatively, as well as a food supplement to help regenerate healthy joint fluid.
