INDICATIONS: Recurrent upward fixation of patella with locking.
The patella is a large sesamoid bone which develops in the tendon of quadriceps femoris muscle. It is connected to the femur by collateral ligaments and to the cranial tibial tuberosity by patellar ligaments. The patellar ligaments, medial, middle and lateral, are the continuations of the fibrous bands of the quadriceps muscle to the cranial tibial tuberosity. The middle patellar ligament is thick and strong as compared to other two ligaments. The medial patellar ligament is widely separated from the middle patellar ligament at both the ends. The lateral patellar ligament is flat and lies close to the middle ligament at both the extremities.
In the medial aspect of stifle joint where medial patellar ligament inserts into the inner aspect of the anterior tibial tuberosity.

Patellar fixation is one of the main functional disorders of the tibia-femoral-patellar articulation (knee joint) in cattle (1) characterized by temporary or permanent dislocation of the patella from its regular position during locomotion (2). Such dislocation may be dorsal, lateral or medial, causing a dorsal, lateral or medial patellar fixation, respectively (3,4,5).
The major potential factors for patellar fixation in cattle are nutrition deficiency, exploitation activity, breed and genetic tendency, external traumas, intense contraction of the crural triceps muscle and morphological changes of the trochlea and medial condyle of the femur (2, 6, 7, 8, 9, 10 ).

Lameness after extended rest is the most typical sign (7). The fixation invokes subtle extension of the limb, phalangeal flexion so that the animal drags the tip of the hoof (3). Diagnosis is based upon anamnesis, clinical signs and local palpation (3, 9), radiography may also be useful (11, 12). Ultrasonography may be ...more
