The International Cartilage Repair Society has set up an arthroscopic grading system by which cartilage defects can be ranked: grade 0: (normal) healthy 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
The main symptom is loss of vision, with colors appearing subtly washed out in the affected eye. A pale disc is characteristic of long-standing optic neuropathy. In many cases, only one eye is affected and a person may not be aware of the loss of color vision until the examiner asks them to cover the healthy eye.
A tear of a meniscus is a rupturing of one or more of the fibrocartilage strips in the knee called menisci. When doctors and patients refer to "torn cartilage" in the knee, they actually may be referring to an injury to a meniscus at the top of one of the tibiae. Menisci can be torn during innocuous activities such as walking or squatting.
Diagnosis can also be made by measuring the replenishment of the tear meniscus. The test can be done as follows: Apply 5 μl of fluorescein to the base of the inferior fornix, maximally deplete the lower tear meniscus by a capillary tube or Weckcel sponge, and then monitor the recovery of the tear meniscus height with or without blinking.

This optic nerve must penetrate through the wall of the eye, and the hole to accommodate this is usually 20-30% larger than the nerve diameter. In some patients the optic nerve is nearly as large as the opening in the back of the eye, and the optic disc appears "crowded" when seen by ophthalmoscopy. A crowded disc is also referred to as a "disc ...
The disease is caused by daily wear and tear of the joint. This process can progress more rapidly as a result of injury to the joint. Osteoarthritis is caused by the break down of the smooth surface between two bones, known as cartilage, which can eventually lead to the two opposing bones coming in direct contact and eroding one another.
Nerve compression is a result of poor posture, prolonged computer use is an example of repetitive strain injury which affects the musculoskeletal system. [16] [2] Whiplash injury, whereby the force causes strain to the capsule and ligaments of the apophyseal joints of the cervical spine. [7]
Horner's syndrome, also known as oculosympathetic paresis, [1] is a combination of symptoms that arises when a group of nerves known as the sympathetic trunk is damaged. The signs and symptoms occur on the same side (ipsilateral) as it is a lesion of the sympathetic trunk.
