Patellar luxation is a disease of joint structure thatâs passed down from affected dogs to their offspring. In some cases, the bone of the upper limb (the femur) may have a very shallow groove so that the kneecap doesnât always rest in place readily. In others, the tendon that attaches the quadriceps is misplaced so that every time this major muscle is flexed the patella moves towards the center of the body (medial patellar luxation or MPL).
