Fifteen studies for the MAT group and 7 studies for the meniscal scaffold group were identified. In this selection of studies, the average failure rate in the MAT group was 18.7% and average reoperation rate was 31.3%. The average failure rate in the meniscal scaffold group was 5.6%, and average reoperation rate was 6.9%. It appears that although MAT is associated with high reoperation and failure rates, the limited number of studies on both MAT and scaffolds and mainly short-term results of scaffold studies make it difficult to make an objective comparison.
