Medial Patellar Desmotomy for the Correction of Upward Patellar Fixation in Cattle at Upazila Veterinary Hospital, Anowara, Chittagong

Abstract

The Upward Patellar Fixation (UPF) is one of the most common non-inflammatory functional disorders of femoro-patellar articulation in cattle, buffalo, camel and horses. Though the infirmity does not endanger the life of the animal, it hampers locomotion. The animals of both sexes (but more in female) and 3 to 8 years of age are more commonly affected by UPF. The aim of the study was to describe the UPF and surgical procedure, success and post-operative care. A total of 8 cattle, of both sexes, from 3-7 years of age, of different breeds, activities and reproductive categories presenting a clinical diagnosis of patellar fixation were observed. The study was conducted from 1 February to 29 March, 2018 at Anowara Upazila Veterinary Hospital (UVH), with a history of lameness of right hind leg with dragging the tip of hoof and difficulties in walking. The detailed anamnesis and close inspection of the site of the problem confirmed the case as UPF and the cases were undergone for an open surgical intervention of medial patellar ligament desmotomy. The surgical correction was undertaken after securing and aseptic precautions. The medial ligament was cut with a curved knife at the depression site. After the medio-patellar desmotomy the animal stood up and started walking without showing any lameness in each cases. The post-operative therapy was given with the local and systemic antibiotics (SP vet®, 2.5gm), Antihistaminic preparation - pheniramine maleate (Asta vet®, 10 ml) and the animals should not be used for hard work for about 8-10 days.
