Medial Patellar Desmotomy

Medial Patellar Desmotomy is sectioning of the medial patellar ligament for relief of upward luxation of the patella.

Patellar ligament is the continuation of the central portion of the tendon of the quadriceps femoris muscle distal to the patella, extending from the patella to the tuberosity of the tibia; it is single in carnivores, pigs and sheep and triple in horses, cattle and buffalo; called also patellar tendon.

Care should be taken during sectioning of the ligament, if middle patellar ligament is sectioned then limb becomes nonfunctional and animal cannot walk with that limb.
