Reported outcome of matrix-assisted cartilage treatment is 11% treatment failure at 5 years. On the other hand, the glass is more than half full, because 89% of patients do well at 5 years. Abrasion arthroplasty results in approximately 66% survivorship at 20 years; future cartilage restoration outcomes should prove more durable.
