patellar

of or pertaining to the patella.

patellar cartilage
a cartilaginous process borne on the medial side of the patella of horses and cattle.
patellar fossa
the depression in the anterior face of the vitreous humor in which the lens sits.
patellar ligament
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 and cattle; called also patellar tendon.
patellar ligament desmotomy
section of the medial patellar ligament for relief of upward luxation of the patella in horses (and rarely, cattle).
patellar luxation, patellar dislocation
1. a common, congenital or acquired orthopedic abnormality in dogs, causing mild to severe, continuous or intermittent lameness. Medial luxation is more common in toy or miniature breeds, often as an inherited defect and frequently associated with structural abnormalities of the distal femur and proximal tibia. Lateral luxation is less frequent, and occurs more often in large breeds associated with genu valgum.
2. Upward luxation and fixation in cattle presents with temporary or permanent stiffness and extension of the affected hindlimb and the animal drags the tip of the toe. More common in Brahman cattle. The cause is not known. Correction is by medial patella desmotomy.
patellar reflex
involuntary contraction of the quadriceps muscle and jerky extension of the hindlimb when the patellar ligament is sharply tapped. It is often used as a test of nervous system function. Absence of the reflex, together with deficient muscle tone in the limb, suggests paralysis or paresis due to lower motor neuron lesion. Called also quadriceps reflex.

More precisely, the medial soft tissues are stretched, the medial aspect of the patellar cartilage is under-loaded, and the lateral aspect is overloaded.
One scan was eliminated because the patient was under 18 years of age, one scan due to the presence of a total knee arthroplasty, and five scans were excluded because the trochlear cartilage, posterior condyles cartilage, and patellar cartilage were not present simultaneously on any single cut due to patella alta.
Although the presence of patellar tilt usually implies a tight lateral retinaculum and unhealthy pressure distributions within the patellar cartilage, it is possible for the bony portion of the patella to appear tilted while the articular cartilage is in fact fully congruous in a medial-lateral direction (a patella is never congruous in the sagittal plane).
My patella is "laterally tilted" and "slightly laterally subluxed," and there is "moderate to marked" thinning and irregularity of the patellar cartilage, "esp[ecially] along the lateral facet.
