This condition is osteoarthritic in nature.

Damage may also be the result of a direct blow to the knee. Chondral injuries may accompany an injury to a ligament, such as the anterior cruciate ligament.

What is high grade chondral fissuring?

Grade I: Softening and swelling of cartilage. Grade II: Fragmentation and fissuring, less than 0.5-in diameter. Grade III: Fragmentation and fissuring, greater than 0.5-in diameter. Grade IV: Erosion of cartilage down to exposed subchondral bone.

How is a chondral defect treated?

This treatment involves using the patient's own cartilage cells. The patient's articular cartilage cells are arthroscopically removed from the injured knee and grown outside the body in tissue culture. After a growth period of three weeks, a second surgical procedure is performed to implant these cells into the defect.

How long is recovery after knee cartilage surgery?

This continual motion supports good nourishment to the cartilage cells.” Most patients are able to return to some physical activity after six to eight weeks, but full recovery after cartilage repair surgery can take anywhere from three to six months.

What causes chondral fissuring?

An articular cartilage injury, or chondral injury, may occur as a result of a pivot or twist on a bent knee, similar to the motion that can cause a meniscus tear.

What is full thickness chondral loss of the knee?

Treatment of Chondral (Cartilage) Lesions. Cartilage, or chondral, damage is known as a lesion and can range from a soft spot on the cartilage (Grade I lesion) or a small tear in the top layer to an extensive tear that extends all the way to the bone (Grade IV or "full-thickness" lesion).

Is meniscus the same as cartilage?

Knee Cartilage

One of the types of cartilage is called articular cartilage. The meniscus is a different type of cartilage that forms a shock absorber between the bones. 1? The meniscus is not attached to the bone like the articular cartilage, but rather sits between the bone ends to cushion the joint.

What is a chondral ulcer?

Chondral lesions are caused through degradation of joint cartilage, in response to metabolic, genetic, vascular and traumatic stimuli. They can occur because of a single episode of overload on the knee joint, or through several cyclical episodes of small magnitude.

What causes Chondrosis?

The most common cause is abnormally accelerated “wear and tear” of this protective cartilage layers within your knee. It can develop from a prior injury or loss of the shock absorbing fibrocartilage (meniscus) within the inner (medial) weight-bearing compartment of your knee.

What is a Grade 4 chondromalacia patella?

Grade 3 shows thinning of cartilage with active deterioration of the tissue. Grade 4, the most severe grade, indicates exposure of the bone with a significant portion of cartilage deteriorated. Bone exposure means bone-to-bone rubbing is likely occurring in the knee.

What does full thickness cartilage defect mean?

Krych, M.D., "Full-thickness defects do not heal spontaneously and have limited ability to heal due to declining function of chondrocytes and the avascular nature of cartilage. Untreated, these lesions can progress to more-serious degenerative joint conditions."
