Вывих коленной чашки. Врожденный вывих 4 степени

A ‘luxating patella’ means that the kneecap (or patella) is slipping out of its normal position in the groove of the thigh bone. Don’t worry, you won’t need X-ray vision to notice that your dog’s kneecap is out of place. Instead, what you’ll usually see is your dog limping or walking with the affected leg in an abnormal position for a few seconds, and then going back to their normal stride once the kneecap has popped back into place.
