Striking of the patellar tendon with a reflex hammer just below the patella stretches the muscle spindle in the quadriceps muscle. [2] [3] This produces a signal which travels back to the spinal cord and synapses (without interneurons) at the level of L3 or L4 in the spinal cord, completely independent of higher centres. [4]
Knee jerk or patellar reflex — a kick caused by striking the patellar tendon with a tendon hammer just below the patella, stimulating the L4 and L3 reflex arcs. Moro reflex , a primitive reflex — only in all infants up to 4 or 5 months of age: a sudden symmetric spreading of the arms, then unspreading and crying, caused by an unexpected ...
Pallesthesia (\ˌpal-es-ˈthē-zh(ē-)ə\), or vibratory sensation, is the ability to perceive vibration. [1] [2] This sensation, often conducted through skin and bone, is usually generated by mechanoreceptors such as Pacinian corpuscles, Merkel disk receptors, and tactile corpuscles. [1]
This first way is the patellar tap. It is to squeeze the fluid between the patella and the femur by pressing at the medial patella using a non-dominant hand. Then, using the dominant hand to press on the patella vertically. If the patella is ballotable, then patellar intra-articular effusion is present. Another way is the milking of the patella.

Specialty: Orthopedics, sports medicine: Symptoms: Pain in the front of the knee [1] Usual onset: Gradual [2] Causes: Unclear [1] Risk factors: Trauma, increased training, weak quadriceps muscle [1] Diagnostic ...
Over the last year, I have gotten a sharp pain and a catching sensation on the front outside part of my left ankle when I play. It now limits my ability to run to the ball laterally and twist to ...
The patellar plexus is a nerve plexus within the subcutaneous tissue overlying and surrounding the patella [1] [2] and ligamentum patellae. [1] It is a fine network of communicating nerve fibres.
