What causes chondral fissuring?
Repetitive activities, such as squatting or lunging, may overload the cartilage and cause it to crack, ultimately leading to chondral fissuring.
How is chondral fissuring treated?
The treatment for chondral injurys ranges from conservative, to arthroscopic and open surgeries (arthroscopic debridement, marrow-stimulating techniques, autologous chondrocyte transfers and implantation, and allografts), and would depend on the patient’s, age, etiology, grade, and quality of the lesion.
What is chondral fissuring?
Chondral Flap (Cartilage separates from the bone and moves like a door with a hinge at one end) Chondral Fracture (Cartilage separates from the bone and floats free)
What causes osteochondritis dissecans?
Osteochondritis dissecans is a bone and cartilage condition that most often occurs in the knee. It has no known cause, but repetitive stress on the joint, low vitamin D and a genetic predisposition are often linked to this condition.
What is Condral?
A chondral defect refers to a focal area of damage to the articular cartilage (the cartilage that lines the end of the bones). An osteochondral defect refers to a focal area of damage that involves both the cartilage and a piece of underlying bone.
What causes full thickness cartilage loss?
Injury or Condition Cartilage cracking, fragmentation and erosion over time has resulted in full-thickness loss of your weight-bearing (articular) cartilage, often altering the alignment of your lower extremity towards bowing (bow-legged).
What is a Grade 3 chondral defect?
Chondral damage is graded from mild to severe, and all grades can have characteristics of osteoarthritis. Grade I – The cartilage “blisters” and becomes soft in the earliest form of damage. Grade II and III – As the condition worsens, the cartilage may become fibrillated (it has a shredded appearance).
Is OCD in the knee rare?
OCD is a relatively rare disorder, characterized by a focal area of subchondral bone that undergoes necrosis.
What is a deep cartilage fissure?
Chondral fissures are a type of chondral injury more accurately cracks or crevices of cartilage extending from the articular surface to the deeper chondral layers. They usually develop as a result of high compressive forces 1 and are often found in the patellar or trochlear cartilage.
What is a chondral fissure?
Home › World View › What Is a Chondral Fissure? What Is a Chondral Fissure? A chondral fissure is a narrow crack that appears on articular knee cartilage in Grade II or Grade III chondral knee injuries.
What is a chondral defect?
Chondral Defect. Any portion of the joint is prone to injury. A common injury to the knee is a localized loss of cartilage, referred to as the chondral defect, which combines with an injury to the supporting bone. A chondral defect can also lead to a small cyst in the top of the bone, just under the cartilage, as a result…
What causes a chondral lesion in the knee?
Sometimes a piece of cartilage breaks off and causes more damage to the cartilage and bone as it is ground in the joint. Common chondral lesions in the knee are: Chondromalacia / Degenerative Chondrosis (Cartilage tears away unevenly, with shallow walls)
What is the pathophysiology of a chondral fracture?
Introduction Chondral and osteochondral injuries are relatively common in weightbearing joints of the lower extremity. Pathology can range from a simple contusion of the articular cartilage and subchondral bone to a fracture involving the cartilage alone or cartilage and underlying subchondral bone together.
