Articular Cartilage Paste Grafting is a viable option for patients with traumatic or arthritic chondral defects. It is performed as an outpatient, single arthroscopic procedure and offers the possibility of significant pain relief and a reduction of associated symptoms. The utilization of the extra cellular matrix inherent in articular cartilage and cancellous bone seems to provide an adequate healing environment for cartilage regeneration. However, normal hyaline articular cartilage is still not produced. Paste grafting for arthritic areas in the knee provides durable tissue and pain relief up to 12 years. There are no complications -according to Dr Stone- and no significant risk to the procedure. Of 145 patients that underwent paste grafting over 12 years, 20 patients were lost to follow-up, (2 deceased, 18 no response to contacts), leaving 125 available for evaluation. 105 were considered successful by at least one grade of improvement in the the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) pain scale of 0-3. 2 patients had no improvement and 18 patients’ pain worsened over time, 10 of which underwent joint arthroplasty, and were considered failures. Therefore, 105 of 125 (84%) patients available for follow-up were successfully treated. WOMAC pain and functioning scores improved significantly, with corresponding p-values of 0.0001 and 0.008. There were no significant differences due to age nor gender. The percent of successful outcomes compares favorably to other techniques. A critical component of the success of this procedure is careful adherence to a post-operative rehabilitation program.
