Researchers have generally accepted that those defects that penetrate the subchondral bone (full-thickness defects) are repaired with various tissues, from a fibrous tissue to fibrocartilage
As stated previously, fibrocartilage
has inferior mechanical and wear properties compared to native hyaline cartilage.
Examination of the condylar head and glenoid fossa usually reveals what appears to be intact fibrocartilage
covering the structures, without evidence of erosion or osteophytic formation.
MR arthrography can be very useful for evaluating the triangular fibrocartilage
This revealed dense fibrous connective tissue, fibrocartilage
, and focal calcifications, but no evidence of malignancy.
This unique joint can perform both hinge and sliding functions and is the only synovial joint in humans whose articulating surfaces are covered by fibrocartilage
does not usually stand up over time and typically wears down after a few years, and may require a repeat procedure.
The interposed capsule undergoes metaplasia and becomes fibrocartilage
The menisci are crescent-shaped pads of fibrocartilage
located between the femur and tibia in the knee, and act as shock absorbers to prevent friction between the two bones.
leads to the formation of fibrocartilage
that is mechanically inferior
Rarely, there may be fibrocartilage
or elastic cartilage elements.
The meniscus is a wedge-shaped fibrocartilage
tissue located between the thighbone and shinbone of the knee, providing stability, load distribution, force transmittance and assistance in lubrication of the knee joint.
At the microscopic level, the tendon fibrils of the supraspinatus tendon inserts directly into the greater tuberosity of the proximal humerus through four zones: tendon, unmineralized fibrocartilage
, mineralized fibrocartilage
, and finally bone.
Orteq has developed a biodegradable, biocompatible polymer scaffold, Actifit, specifically designed to support tissue ingrowth and regeneration in the meniscus, a fibrocartilage
cushion in the knee.
Incidentally, chondrocalcinosis was seen in the triangular fibrocartilage
