This study hypothesis is that MAT in patients with advanced chondral damage can obtain good clinical outcomes, equivalent to patients with minimal chondral damage.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>A prospective longitudinal study of 99 consecutive patients who underwent MAT between May 2005 and Feb 2013, with a minimum of 1\u2010year follow\u2010up. Patients were categorised into two groups: 60\u00a0in Group A (Good) up to ICRS Chondral grade 3b involving &lt;1\u00a0cm<jats:sup>2<\/jats:sup> and 39\u00a0in Group B (Bare) ICRS grade 3b involving &gt;1\u00a0cm<jats:sup>2<\/jats:sup> or worse. Outcomes were assessed by PROMS (KOOS, IKDC, Lysholm, Tegner Activity Scale), with an endpoint of meniscal allograft failure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Mean follow\u2010up was 2.9 years (range 1.1\u20139.1, SD 1.23), with a similar male to female and lateral to medial ratios between the groups (n.s). The age of Group B was significantly older than Group A (35 vs 29 years, <jats:italic>p<\/jats:italic> = 0.002). The status of the articular cartilage at the time of transplant was directly related to the number of years since index meniscectomy [(A) Mean 6.9 years, SD 6.3; (B) 11.9 years, SD 7.4; <jats:italic>p<\/jats:italic> = 0.001]. Pre\u2010operatively, patients in Group B had significantly worse pain and functional outcome scores (KOOS <jats:italic>p<\/jats:italic> = 0.022, Lysholm <jats:italic>p<\/jats:italic> = 0.025, IKDC pain subset <jats:italic>p<\/jats:italic> = 0.035). The mean increase PROMs was significant in both groups at 1 year (KOOS <jats:italic>p<\/jats:italic> &lt; 0.05, IKDC <jats:italic>p<\/jats:italic> &lt; 0.001, Lysholm <jats:italic>p<\/jats:italic> &lt; 0.001), and the pain and functional scores were no longer significantly different between groups (n.s.). The outcome measures continued to improve in both groups at 2 and 3 years, with slightly greater improvement in Group A. Failure of the meniscal allograft occurred in 9 patients (A:1, B:8) at a mean time of 1.1 years (SD 0.55). Kaplan\u2013Meier survival at 2 years was 97.9 % (A) and 78 % (B) (<jats:italic>p<\/jats:italic> = 0.002). Logistic regression analysis demonstrated a relationship between survival and chondral grade (<jats:italic>p<\/jats:italic> = 0.001) and number of concomitant procedures (<jats:italic>p<\/jats:italic> &lt; 0.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Patients with advanced chondral damage should not be excluded from MAT.
