History

A 14-year-old 12.5-kg (27.5-lb) female mixed-breed dog with a recent diagnosis of hyperadrenocorticism and diabetes mellitus was evaluated as part of a recheck examination and because of lack of appetite, which had worsened in the last few weeks, and episodes of panting that lasted several hours. Further recent medical history included hind limb trembling and hospitalization for hypoglycemia-induced seizures. The dog vomited once while in the examination room. During recheck examination, muscle wasting and a decrease in proprioception in the hind limbs were observed, and the abdomen was tense on palpation. Findings of serum biochemical analysis were consistent with

History

A 10-year-old 18-kg (39-lb) spayed female mixed-breed dog was referred to the veterinary teaching hospital for evaluation of transitional cell carcinoma of the bladder, diagnosed 1 year previously via histologic examination of an ultrasound-guided fine-needle aspirate of a trigone mass. Treatment with piroxicam (0.3 mg/kg [0.14 mg/lb], PO, q 24 h) was started. Stable disease was noted on subsequent serial recheck ultrasonography by the referring veterinarian. During the year between diagnosis and referral, multiple urinary tract infections with various strains of Escherichia coli were treated with enrofloxacin, nitrofurantoin, cefdinir, and amoxicillin. One month prior to referral, the

History

An 8-year-old spayed female German Shepherd Dog was brought to its veterinarian because of signs of lethargy and inappetence with weight loss. Hepatomegaly was evident on radiographic views of the abdomen; lymphoblasts and mitotic cells were identified on cytologic evaluation of a fine-needle aspirate of the enlarged liver. Treatment with lactulose and metoclopramide was initiated. Three weeks later, the patient was referred for chronic liver disease and recent collapse.

Pale mucous membranes with a slightly icteric tinge and an extremely prolonged capillary refill time were noted on referral physical examination. The dog was nonambulatory with signs of depression but

History

A 9-year-old castrated male Italian Greyhound that weighed 5.6 kg (12.3 lb) was admitted to the emergency service for a 5-day history of exercise intolerance and possible difficulty breathing and a 3-day history of gagging and coughing. The dog had fallen off the bed and developed a large contusion on the right side of the ventral aspect of the thorax 2 weeks previously, which had since resolved. The dog was bright, alert, responsive, and stable at the time of admission. Respiratory sounds were decreased to undetectable in the right middle to caudal lung field region. Abnormal laboratory values included

Abstract

Objective—To describe clinical signs and results of treatment in cats with patellar luxation.

Design—Retrospective case series.

Animals—42 cats in which patellar luxation had been diagnosed on the basis of results of palpation of the stifle joints.

Procedures—Degree of luxation was graded on a scale from 1 to 4, and severity of lameness was graded on a scale from 0 to 5. Radiographs of stifle joints were evaluated for signs of osteoarthritis. Long-term function was classified as poor, fair, good, or excellent.

Results—34 cats had bilateral luxation and 8 had unilateral luxation. Only 7 (17%) cats had a history of trauma. Mean age of the cats was 3.3 years, and mean weight was 4.26 kg (9.4 lb); 26 (62%) were domestic shorthairs. Seventy-three of the 76 (95%) affected joints had medial patellar luxation. Luxation grades could be assigned to 65 joints, with grade 2 (30 joints) and 3 (22 joints) luxation being most common. Lameness grades could be assigned to 73 joints, with grade 1 lameness (27 joints) most common. Outcome was excellent for 8 of 17 joints treated without surgery and for 23 of 35 joints treated surgically. Complications attributable to surgery were reported in 8 cats.

Conclusions and Clinical Relevance—Patellar luxation should be considered as a cause of hind limb lameness in cats. Low-grade luxation can be associated with lameness of the same severity as high-grade luxation. Surgical correction of patellar luxation in cats with grade 2 or 3 lameness can result in a favorable outcome.
