Chondromalacia patellae is sometimes used synonymously with patellofemoral pain syndrome. [4] However, there is general consensus that patellofemoral pain syndrome applies only to individuals without cartilage damage. [4] [5] This condition is also known as Chondrosis.
It is frequently divided into 5 grades, with 0-2 defined as normal and 3-4 defined as diseased. Some common diseases affecting/involving the cartilage ...
grade 1: the cartilage has a soft spot, blisters, or superficial wear; grade 2: minor tears of less than one-half the thickness of the cartilage layer; grade 3: lesions have deep crevices of more than one-half the thickness of the cartilage layer; grade 4: the cartilage tear is full thickness and exposes the underlying (subchondral) bone
Grade IV - the patella is permanently luxated and cannot be manually repositioned, with up to 90° of rotation of the proximal tibial plateau. The femoral trochlear groove is shallow or absent, with displacement of the quadriceps muscle group in the direction of luxation.
Patellar subluxation syndrome is an injury involving the kneecap.Patellar subluxation is more common than patellar dislocation and is just as disabling. [1]In this condition, the patella repetitively subluxates and places strain on the medial restraints and excessive stress/tension on the patellofemoral joint.
Fourth cranial nerve palsy or trochlear nerve palsy, is a condition affecting cranial nerve 4 (IV), [1] the trochlear nerve, which is one of the cranial nerves. It causes weakness or paralysis of the superior oblique muscle that it innervates. This condition often causes vertical or near vertical double vision as the weakened muscle prevents ...
The cause of congenital fourth nerve palsy is unclear in most cases. It may be neurogenic in origin, due to a dysgenesis of the CN IV nucleus or nerve, but a clinically similar palsy may result from absence or mechanical dysfunction (e.g., abnormal laxity) of the superior oblique tendon.
The Cavernous Sinus. Each trochlear nerve originates from a trochlear nucleus in the medial midbrain.From their respective nuclei, the two trochlear nerves then travel dorsal-ward through the substance of the midbrain surrounded by the periaqueductal gray, crossing over (decussating) within the midbrain before emerging from the dorsal midbrain [3] [4] just inferior to the inferior colliculus.
