The study was aimed to determine the accurate location of giving incision and the width of the incision required to correct the problem of upward patellar fixation during blind method of medial patellar desmotomy. We took measurements of patellar ligaments in stifle joint of 50 indigenous and 50 crossbred slaughtered cattle without any apparent musculo-skeletal disorders were analysed. The average length and width of lateral, middle, and medial patellar ligaments for indigenous cattle were 9.360 ± 0.339 and 3.056 ± 0.226; 10.230 ± 0.382 and 2.019 ±0.258; 10.519 ± 0.429 and 2.430 ±0.232; for crossbred cattle 10.636 ± 0.601 and 3.608 ± 0.368; 11.580 ± 0.724 and 2.330 ± 0.205; 12.366 ± 0.710 and 2.890 ± 0.234 cm respectively. The average groove width for indigenous cattle and crossbred cattle between middle and medial ligament were 1.356 ± 0.160 and 1.828 ±0.186 cm and the highest width of groove between middle and medial patellar ligaments from the level of most cranial bulging of the cranial tibial tuberosity in the upward direction were 4.234 ± 0.269 and 5.645 ±0.358 cm respectively. Parameters measured were significantly different (p0.05) between indigenous and crossbred cattle. This study was suggested that incision should be made 4.234 ± 0.269 and 5.645±0.398 cm proximally from the level of the most cranial bulging of cranial tibial tuberosity at the groove between middle and medial patellar ligaments, 2.430 ±0.232 and 2.890±0.186 cm the mean width of the medial ligament to be cut during blind method of medial patellar desmotomy in indigenous and crossbred cattle respectively during surgical correction of upward patellar fixation.
