The clinical outcomes of ACI with concomitant MAT were inferior to those of isolated ACI.



The purpose of this study was to compare the clinical outcomes and survival rate of ACI with or without concomitant MAT.


Patients who underwent ACI of the medial or lateral femoral condyle with or without concomitant MAT were retrospectively reviewed. There were 14 patients (mean age, 31.2 ± 9.9 years) who underwent isolated MAT and 19 patients who underwent ACI with concomitant MAT (mean age, 34.8 ± 8.4 years). The International Knee Documentation Committee (IKDC) subjective score, Lysholm score, Tegner activity score, and 10- to 15-year survival rate were compared between groups.


At final follow-up, the IKDC subjective score was superior in isolated ACI (75.8 ± 18.4) than ACI with MAT (61.0 ± 16.6, p = 0.024). The Lysholm score was also higher in isolated ACI (77.5 ± 19.1) than ACI with MAT (62.5 ± 18.1, p = 0.029). The Tegner activity score did not differ between treatments (isolated ACI, 5.3 ± 1.1; ACI with MAT, 4.5 ± 1.3; p = 0.072). There was a non-significant trend for survival rate to be greater in isolated ACL than ACL with MAT (p = 0.19).


The clinical outcomes of ACI with concomitant MAT were inferior to those of isolated ACI. The long-term survival rate of isolated ACI was higher than that of ACI with concomitant MAT, but not significantly so.
