Race is a significant factor for this injury, where Hispanics, African-Americans and Caucasians had slightly higher rates of patellar dislocation due to the types of athletic activity involved in: basketball (18.2%), soccer (6.9%), and football (6.9%), according to Brian Waterman. [23] Lateral Patellar dislocation is common among the child ...
In horses and oxen, the distal part of the tendon of insertion of quadriceps ("below" the patella) is divided into three parts. An elaborate twisting movement of the patella allows the stifle to "lock" in extension when the medial portion of the tendon is "hooked" over the bulbous medial trochlear ridge of the distal femur.
The most likely time for the patella to shift laterally is during the first 20–30 degrees of flexion as the quadriceps tighten simultaneously and pull the patella laterally. Beyond 30 degrees, the quadriceps tendon and patellar ligament pull the patella posterior into the groove of the knee joint making lateral dislocation of the patella ...
A luxating patella, sometimes called a trick knee, is a condition in which the patella, or kneecap, dislocates or moves out of its normal location. It can be associated with damage to the anterior cruciate ligament. [1] Patellar luxation is a common condition in dogs, particularly small and miniature breeds. [2]
Femur: the largest long bone in a horse. Proximally it forms a ball-and-socket joint with the pelvis to form the hip joint, and distally it meets the tibia and patella at the stifle joint. It serves as an attachment point for the deep and middle gluteal muscles, and the accessory and round ligaments. Patella; Tibia: runs from stifle to hock ...
At the stifle joint, a "hook" structure on the inside bottom end of the femur cups the patella and the medial patella ligament, prevents the leg from bending. [5] Cattle have a stay apparatus which allows them to rest individual limbs, [3] but cattle generally do not sleep standing up. [6] The ancient Dinohippus had a rudimentary stay apparatus

Knee: Patellar dislocation. Many different knee injuries can happen. Three percent of knee injuries are acute traumatic patellar dislocations. [26] Because dislocations make the knee unstable, 15% of patellas will re-dislocate. [27] Patellar dislocations often occur when the knee is in full extension and sustains a trauma from the lateral to ...
