Thirty two dogs with luxation of patella were included in the study. Based on the clinical presentation of the dogs, they were divided into two groups. Seventeen dogs with luxation of patella and minimum conformational defects were included in Group I and treated with trochlear wedge recession sulcoplasty and retinacular imbrication sutures. Fifteen dogs with luxation of patella and severe conformational defects were included in Group II and were treated with a combination of trochlear wedge recession sulcoplasty and transposition of tibial tuberosity along with retinacular imbrication sutures. Relocation of quadriceps femoris muscle group was done wherever necessary. All the dogs in Group I showed complete recovery from lameness following surgery. All the dogs except four in Group II recovered from the clinical signs following surgery. Two dogs with Grade IV bilateral luxation of patella with severe joint stiffness, which were presented very late for the treatment, did not show marked improvement. Two dogs, where joint stiffness was not acute, did recover partially, and lameness and pain at stifle and hip joints persisted due to degenerative joint disease. It was concluded that these two treatment regimens could be successfully employed in the correction of varying degrees of patellar luxation provided the accompanying complications were not very severe and the cases were subjected to surgical correction at the earliest.
