New procedure bests standard of care for fixing damaged cartilage
Date:2/7/2012

a variety of tools commonly used to measure outcomes in patients undergoing these types of procedures. They used the short-form (SF)-36 health survey, a 36-question scale that includes a gamut of questions about general health and is widely used across all fields of medicine. They used two knee specific questionnaires: the international knee documentation committee (IKDC) scores and the Knee Outcome Survey (KOS). And they used the Marx Activity Level that is scored on a scale from 0 to 16 and gauges a person's ability to do four activities: running, cutting, decelerating, and pivoting.

They found no difference in the knee outcome surveys or SF-36 form, but they did identify significant differences in the Marx Activity Level. Patients who underwent the OATS procedure had higher scores than patients who underwent microfracture at one year from baseline (score 5.21 vs. 4.11), two years (7.29 vs. 3.71), three years (7.75 vs. 2.91) and five years (8.55 vs. 2.89).

"The Marx activity rating scale correlates directly to the amount of physical activity that you can do at the time of the assessment," said Dr. Williams. "Patients who underwent the OATS were able to do more sports and more athletic activities compared to the microfracture group at the same time point. We now have another procedure which is likely to result in a return to sport more predictably."

He said the results are not surprising given that the OATS repair results in a natural cartilage repair whereas microfracture results in a repair comprised mainly of fibrocartilage that has been shown to be biomechanically inferior to articular cartilage.

Dr. Williams is the head team physician for the Nets NBA basketball team and the Major League Soccer's New York Red Bulls.
