Johnson LL. Arthroscopic abrasion arthroplasty: a review. Clin Orthop Relat Res. 2001;(391 Suppl):S306-17. doi:10.1097/00003086-200110001-00028.

Abstract

Arthroscopic abrasion arthroplasty is an elaborate description for an extensive multiple tissue debridement for patients seeking an alternative to total knee replacement. The operation is palliative, not curative. In patients seeking an alternative to total knee replacement, the definitive operation may be avoided or deferred in a high percentage of patients as many as 5 years. Because the abrasion portion of the operation is accompanied by multiple tissue type debridement, it is not known what clinical benefit the abrasion aspect contributes. Furthermore, no prospective randomized clinical studies have been done and most clinicians reporting on their experience with the procedure have varied the indications, technique, and/or postoperative treatment. Future investigation may answer these clinical questions. It is known that fibrocartilage forms at the abrasion site. The reparative tissue has many of the characteristics of cartilage, but does not have the biomechanical properties of articular cartilage. The fibrocartilage has shown durability for many years confirmed during opportunistic second look arthroscopy. The applications of growth factor science or genetic engineering may provide means of converting the regenerative tissue of abrasion arthroplasty to mature articular cartilage.
