Instructional course 206 covers the various approaches to articular cartilage injury
currently in use and offers some insight into what the future might hold. The participants
address different elements of the same issue. In the past the therapies available
for full thickness articular cartilage lesions on the weight bearing surfaces of the
knee included arthroscopic debridement of the lesion, abrasion arthroplasty, attempts
at fragment reattachment, and the placement of holes into the subchondral bone. Whether
these holes were created by a drill or a pick (microfracture) the result was a fibrocartilage
patch and the clinical results were improvement in 75% at 3 to 5 years. No type 3
cartilage was produced and these techniques do not prevent degenerative joint disease
in the long term.
