Do chondral defects heal?
Articular cartilage does not respond well to healing. Damage to the articular cartilage eventually degenerates into arthritis. The goal of current techniques for chondral defects is to prevent the degenerative process by regenerating hyaline like cartilage.
What is full thickness cartilage?
A full-thickness cartilage defect was defined as evidence of denuded subchondral bone, regardless of size, on either the weight-bearing femoral condyle or tibial plateau. Osteophytes were not included in any measurements of subchondral bone or cartilage.
What is a full thickness lesion?
Injuries to the articular cartilage in the knee joint are common. These injuries, called lesions, often show up as tears or “pot holes” in the surface of the cartilage. If a tear goes all the way through the cartilage, doctors call it a full-thickness lesion.
Is a chondral defect arthritis?
Background: Focal chondral defects (FCDs) of the knee are believed to contribute to the development of osteoarthritis (OA), resulting in pain and dysfunction.
Is osteochondral defect hereditary?
The causes of an osteochondral defect of the knee are still unclear; however, some theories include deficient blood supply to the injured region, direct trauma, repetitive strain, or heredity.
Can osteochondritis be cured?
Treatment of osteochondritis dissecans is intended to restore the normal functioning of the affected joint and relieve pain, as well as reduce the risk of osteoarthritis. No single treatment works for everybody. In children whose bones are still growing, the bone defect may heal with a period of rest and protection.
Why does bone thicken in osteoarthritis?
In osteoarthritis, the normally smooth cartilage surface softens and becomes pitted and frayed. As the cartilage breaks down, the joint may lose its normal shape. The bone ends thicken and form bony growths or spurs where the ligaments and capsule attach to the bone.
Is surgery necessary for osteochondritis dissecans?
Nonsurgical options include: Healing of the osteochondritis dissecans lesion should be monitored by routine follow-up imaging tests. In many younger children who still have a lot of growing to do, the lesion often heals on its own. Surgical intervention may be needed if nonsurgical treatment is not effective.
How serious is osteochondritis?
Osteochondritis dissecans (os-tee-o-kon-DRY-tis DIS-uh-kanz) is a joint condition in which bone underneath the cartilage of a joint dies due to lack of blood flow. This bone and cartilage can then break loose, causing pain and possibly hindering joint motion.
What is a chondral defect?
A chondral defect refers to a focal area of damage to the articular cartilage (the cartilage that lines the end of the bones).
Is there evidence-based treatment for chondral lesions of the hip?
While long-term outcome studies on knee cartilage replacement and repair are becoming more prevalent in the literature, definitive evidence-based treatment guidelines for chondral lesions of the hip have lagged behind [3, 4••, 5].
How deep is a round defect in the femoral head?
A round defect (14 mm diameter, 16 mm depth) was identified on the posterior non-weight-bearing portion of the femoral head. A mosaicplasty with an open approach was undertaken using 4 cylindrical osteochondral grafts from the lateral femoral condyle.
What is the role of CPM in the treatment of chondral defect?
Improvement of full thickness chondral defect healing in the human knee after debridement and microfracture using CPM. Am J Knee Surg. 1994; 7:109-116.
