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.

This prospective study was conducted on patients with recurrent patellar dislocation that was clinically diagnosed in Peking University Third Hospital between January 2014 and October 2014.
This procedure is usually performed under local anaesthetic, so that the medial patellar ligament is clearly defined.
The surgeries were indicated in patients with recurrent patellar dislocation with: torn MPFL, minor or moderate trochlear dysplasia, and no serious cartilage damage (Outerbridge grades 3 or 4) established by X-ray, magentic resonance imaging or previous arthroscopic findings [9, 11].
We also wanted to study if neovascularization of the patellar tendon was visible with color flow imaging (CFI) in patients with lasting symptoms after surgical treatment.

Our case shows the possibility of gout involvement of quite a rare site such as the patellar tendon and underlines the importance of early diagnosis with advanced imaging modalities to facilitate management of disease.
In the present study, different complications were noticed during and after medial patellar desmotomy in different group of animals, (Table-2).
Patellar dislocations are an orthopaedic condition that can be the result of either direct trauma or low energy twisting mechanisms, where the majority of dislocations occur laterally.
Bilateral patellar tendon ruptures are rare, especially amongst patients with no predisposing factors for tendinopathy [1].
Some of the disadvantages include risk of patella fracture, patellar tendonitis, anterior knee pain, and loss of sensation.
