What is partial thickness chondral?

Partial thickness defects arise when only the articular cartilage layer is damaged; the degradation and loss of the ECM proteoglycans and collagen fibrous networks follow after the trauma.

What does chondral flap mean?

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 a chondral flap?

Causes Articular Cartilage Fissure An articular cartilage injury, or chondral injury, may occur as a result of a pivot or twist on a bent knee, a direct blow to the knee, or wear and tear as a patient gets older.

What is a cartilage flap?

Flaps: Flaps in the articular cartilage occur when part of the cartilage separates from the bone and can be lifted from its normal position. This can also lead to catching sensations with knee movement. Defects: Cartilage defects can lead to exposed bone within the joint.

What does full thickness chondral defect mean?

A chondral defect refers to a focal area of damage to the articular cartilage (the cartilage that lines the end of the bones).

What is full thickness defect?

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.”

What does full thickness chondral loss mean?

What does full thickness cartilage defect mean?

What does full thickness cartilage loss mean shoulder?

Full thickness chondral defects and osteochondral defects of the shoulder can cause numerous problems for the patient such as pain, swelling, locking, and may lead to early osteoarthritis.

What causes full thickness cartilage defect?

Articular cartilage defects may be the result of degeneration from age, repetitive wear and tear, or a traumatic event such as an injury from falling on the knee, jumping down, or twisting the knee. Sometimes, these injuries also occur in relation to a fracture or ligamentous injury in the knee.

What is full thickness Chondrosis?

Injury or Condition Cartilage cracking, fragmentation and erosion over time has resulted in full thickness loss of your weight-bearing (articular) cartilage, exposing bone and often altering the alignment of your lower extremity (knock-kneed). This condition is also referred to as osteoarthritis.

What causes cartilage loss in shoulder?

Osteoarthritis is the most common cause of cartilage damage in the shoulder, becoming more prevalent with age and with repetitive use of the joint. Arthritis is also more likely to occur if you’ve had a previous shoulder injury.

What is a Grade 3 chondral flap?

Chondral Flap (Cartilage separates from the bone and moves like a door with a hinge at one end) Grade III: full thickness fissures, to subchondral bone >1 cm diameter Rule out malalignment, meniscal tear, ligamentous instability, extensor mechanism problems, as symptoms are mostly similar

What is an osteochondral fracture/chondral flap?

Osteochondritis Dissecans / Osteochondral Fracture (Cartilage breaks away with a piece of the bone) Chondral Flap (Cartilage separates from the bone and moves like a door with a hinge at one end)

What are the different grades of chondral damage?

Overview. 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).

What is a chondral lesion on the knee?

Common chondral lesions in the knee are: Chondromalacia / Degenerative Chondrosis (Cartilage tears away unevenly, with shallow walls) Osteochondritis Dissecans / Osteochondral Fracture (Cartilage breaks away with a piece of the bone) Chondral Flap (Cartilage separates from the bone and moves like a door with a hinge at one end)
