This study demonstrated that limited medial meniscal RD was present
preoperatively but increased by 2 mm after scaffold implantation. Lateral RD was
also present preoperatively but did not increase after scaffold implantation.
Importantly, a strong negative correlation was found between the rim and
postoperative medial RD; a thicker rim limited RD. However, in the lateral
compartment, rim thickness did not correlate with RD because RD was already
strongly present preoperatively. Finally, no correlations were observed between
scaffold RD and clinical outcome scores, either preoperatively or postoperatively.
