Abstract

Medial meniscal root tears have been repaired using various methods. Arthroscopic all-inside repair using a suture anchor is one of the popular methods. However, insertion of the suture anchor into the proper position at the posterior root of the medial meniscus is technically difficult. Some methods have been reported to facilitate suture anchor insertion through a high posteromedial portal, a posterior trans-septal portal, or a medial quadriceptal portal. Nevertheless, many surgeons still have difficulty during anchor insertion. We introduce a technical tip for easy suture anchor insertion using a 25° curved guide and a soft suture anchor through a routine posteromedial portal.

Figure

  • Fig. 1 Preoperative planning of portal positions in the right knee. Anterolateral (AL) portal as viewing portal, anteromedial (AM) portal as a main working portal located just medial to the patella tendon, and far anteromedial (fAM) portal used for shuttle relay.

  • Fig. 2 (A) The tear margin of the posterior root of medial meniscus (MM; black asterisk) is debrided using a motorized shaver (white asterisk). (B) Preparation of the insertion site using a curved curette (Ⓒ). (C) Posterior one-third of the meniscus (black dotted line), 7–8 mm medial to the torn edge, is penetrated using a curved suture hook (Ⓗ). (D) The anterior one-third of the meniscus (white dotted line) is penetrated in the same manner. PCL: posterior cruciate ligament, MFC: medial femoral condyle.

  • Fig. 3 A posterior medial portal (asterisk) is established by the transillumination technique at the center of soft spot, 1–1.5 cm proximal to the joint line and 1 cm posterior to the medial femoral condyle.

  • Fig. 4 (A) Comparison of a flexible reamer (1) and a 25° curved suture anchor guide (3) with a straight guide (2). (B) The tip of a 25° curved guide (Ⓖ) is placed on the footprint of the posterior root of the medial meniscus vertically. (C) Under visualization through an anterolateral portal, a soft suture anchor along the curved guide (arrow) is inserted through a posteromedial portal at an angle of 30° with the knee flexed at 60°. (D, E) Schematic diagram showing the knee position and insertion of the curved guide through the posteromedial portal. PCL: posterior cruciate ligament, MFC: medial femoral condyle.

  • Fig. 5 (A) One limb of the polydioxanone suture (PDS, arrowhead) from the inferior side and one strand of Force Fiber (arrow) are retrieved using a suture retriever (asterisk) along a cannula through an anteromedial portal. (B) Shuttle relay by pulling a PDS (arrow) at far anteromedial portal is made to pass the Force Fiber through the meniscus from inferior to superior. (C) Two sutures are tied securely, and the posterior root of the medial meniscus (MM) is repaired to the insertion site. MFC: medial femoral condyle, PCL: posterior cruciate ligament.
