Figure 7.
Initial arthroscopy and second-look arthroscopy of the other 4 cases are shown. Case 2 shows degenerative medial meniscus in panel A and implanted scaffold is absorbed on the second-look arthroscopy, indicating poor meniscal repair (E). Case 3 shows degenerative medial meniscus in panel B and panel F shows new soft tissue at the implanted area. However, cheese-cut wiring is found. In case 4, the degenerative medial meniscus is shown in panel C and preserved meniscus-like tissue in panel G. Case 5 shows a degenerative flap tear in panel D; new meniscus-like tissue is observed in panel H.
