Abstract

Patellar fixation is a functional disease seen in cattle's tibia-femoral-patellar articulation. Medial Patellar Desmotomy (MPD) is a surgical procedure used in cattle and equine to treat certain disorders that affect the patella or kneecap in animals, as the lameness associated with the patellar fixation affects the working and feed-searching ability of animals.  The upward fixation of the patella is one of the important diseases of cattle that leads to lameness, reduced production and increased culling of cattle and buffaloes. Mainly, two techniques of MPD, including the stab method and the pinhole method, are used frequently in the field conditions for correction of upward fixation of the Patella. The present study was conducted primarily to study the incidence of cases of upward fixation of patella cattle in Bahawalpur and comparison of its correction techniques, i.e., stab method and pinhole method. It was shown that the incidence of upward fixation of the patella was 0.04% (170 / 4, 20,000). In the current study, data from 170 Cholistani cattle were recorded clinically as having upward fixation of the patella. The condition (upward fixation of the patella) was more prevalent in female cows than in males. There were 30% males (51/170) and the remaining 70% (119/170) were female animals. The total cases that were found in field conditions were treated by two surgical techniques:  the Pinhole method and the Stab method. It was found that the Stab method of surgical correction of upward fixation of the patella was better than the pinhole method, with minimal complications, early recovery, and fast wound healing. It was found that the wound healing was 5.9 times faster in the stab method as compared to the pinhole method, while the odds of age, sex, season, and parity had no significant effect on the wound.
