Treatment options for
damaged knee cartilage
your doctor has several surgical techniques available for treating damaged knee cartilage
(Also called “debridement and lavage”) The doctor trims the damaged cartilage and then cleans the area with sterile water.
Chondroplasty may offer temporary relief but does not repair the cartilage lesion.
Marrow stimulation repairs
(Such as microfracture, abrasion arthroplasty, and subchondral drilling) Blood and bone marrow cells seep out of small holes drilled into the bone, creating a blood clot that forms repair tissue.
Marrow stimulation forms tissue resembling fibrocartilage rather than hyaline cartilage, the durable tissue in normal articular cartilage. This may influence the durability of the repair tissue.¹
osteochondral implants (Autologous or Allograft)
These procedures plug healthy pieces of both cartilage and bone into damaged areas, using either a patient’s own tissue (osteochondral autograft, also called OATS®) or tissue from a cadaver (osteochondral allograft).
Cartilage implants are limited by the ability to procure donor tissue.
MACI (autologous cultured chondrocytes on porcine collagen membrane) is made up of a patient’s own (autologous) cells expanded and placed onto film that can be absorbed back into your own tissue. It is implanted into the area where the damaged cartilage was removed.
