Case records of cattle admitted to 2 university veterinary hospitals during 6 years were evaluated to determine the age, breed, sex, and treatment of cattle with upward fixation of the patella. Affected cattle were compared with those from the respective hospital populations of cattle admitted during the same time.

Of 38 cattle with upward fixation of the patella, 34 were treated surgically. Follow-up evaluation was obtained from owners of 28 of the treated cattle. Surgery was successful in eliminating all clinical signs in 25 of the 28 cattle. There was an increased risk of upward fixation of the patella associated with Brahman and Brahman-type cattle, compared with non-Brahman cattle.

Three available differential stains, Camco-Quik, Diff-Quik, and Wright-Giesma were compared for detection of intraerythrocytic Anaplasma marginale in bovine blood smears. In samples where < 1% to more than 51% of the rbc were infected, statistical analysis of the data indicated no significant difference in the detection of A marginale with Camco-Quik or Diff-Quik stains. However, a significantly lower percentage of infected rbc were detected when blood smears were stained with the Wright-Giemsa stain, compared with the other 2 methods.

Objective—To identify surgical and postoperative complications of tibial plateau leveling osteotomy (TPLO) in dogs with rupture of the cranial cruciate ligament (CCL) and compare their incidence with those reported in the literature for other commonly performed CCL stabilization procedures.

Design—Retrospective study.

Animals—346 dogs undergoing 397 TPLO procedures.

Procedure—Medical records of dogs undergoing 563 consecutive TPLO procedures were reviewed. Complications were recorded and assigned to groups on the basis of the period during which the complication was observed.

Results—397 TPLOs met the criteria for inclusion in the study. Complications (n = 136) were recorded in 113 of the 397 (28%) procedures. Multiple complications developed in 10 dogs. In 19 dogs, a second surgery was performed to manage complications. Development of a complication after surgery was not associated with age or body weight of the dog, tibial plateau angle prior to stifle joint surgery, or experience of the surgeon. Factors significantly associated with complications were breed and performance of an arthrotomy concomitantly with TPLO.

Conclusions and Clinical Relevance—TPLO was associated with development of numerous complications, some of which required surgical correction. Most complications resolved with nonsurgical treatment. Several complications were unique to the TPLO procedure because of the surgical technique and implants required. Although TPLO was associated with a greater number of complications than other CCL stabilization methods, the incidence of major complications was similar. (J Am Vet Med Assoc 2003;222:184–193)
