Fig. 4

Treatment course of patient #4. (a) The left lateral meniscus shows a discoid meniscus with a flap tear in the posterior segment. (b) Following partial meniscectomy, a horizontal tear with degenerative changes is seen in the posterior segment. (c) Vertical sutures were placed arthroscopically using an all-inside device, followed by (d) P47K-WAS-MR gel application with a needle. (e) Postoperative T2-weighted MRI shows grade 2 healing in coronal and sagittal views. (f) Second-look arthroscopy shows an incompletely healed meniscus with views from the Needle Arthroscope® (left) and conventional arthroscopy (right); while sutures are visible, the Needle Arthroscope®’s lower resolution limits probing of the repair site.
