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). An osteochondral defect refers to a focal area of damage that involves both the cartilage and a piece of underlying bone.
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.
What is chondral lesion?
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.
How is full thickness chondral fissure 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 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?
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 a chondral lesion?
Causes and Risk Factors Usually, an osteochondral lesion occurs when there is an injury to the joint, especially if there is an ankle sprain or if the knee is badly twisted. Individuals who play sports such as soccer, football, rugby and golf may be at risk of an osteochondral lesion.
What grade is full thickness cartilage loss?
Grade 3 – Cartilage with Grade 3 changes indicate that there is full thickness fissuring or splitting of the cartilage all the way down to subchondral bone. Grade 4 – Grade 4 chondromalacia indicates that there is complete loss of cartilage with exposed subchondral bone.
How is a chondral defect of the knee treated?
Cartilage transplant or autologous cultured chondrocytes (cartilage cells) on a collagen membrane [MACI] can be used to treat focal cartilage defects. This is a two-stage cell-based procedure, because it requires an initial arthroscopic procedure to harvest the cells (small biopsy from your cartilage).
How do you fix a chondral defect?
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.
What is full thickness chondral wear?
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).
What does the medial femoral condyle do?
The femoral condyle, comprising the medial and lateral condyles, is the expanded distal end of the femur and participates in the formation of the knee joint.
What is medial femoral condyle cartilage?
The femoral condyles are the two rounded prominences at the end of the femur; they are called the medial and the lateral femoral condyle, respectively. The motions of the condyles include rocking, gliding and rotating.
Grade 4 is the most severe and indicates full degradation of the cartilaginous surface exposing bone on bone rubbing.
How long does a medial femoral condyle fracture take to heal?
Medial Femoral Condyle Fracture Study Results Their fractures were fixated using screws and most patients made a full recovery in a few months. The average time for a complete union of the fracture was around 4.5 months. Most patients did not suffer any loss of function, including mobility loss, in the injured limb.
