Bilateral hind limb deformities and subsequent medially luxating patellas in a kitten.

A 9-week-old domestic long-haired kitten was presented for evaluation of bilateral hind limb deformities. Bilateral hyperextension of the tarsi was diagnosed on physical examination and was treated with physical therapy and splinting. At 4 months of age, the patient was presented with bilateral, medially luxating patellas, which were successfully treated with bilateral chondroplasty and joint capsule imbrication.
