2. Fig 1
Use of Deschamps guide (depicted in brown) in a right knee joint. The lateral meniscus (LM; depicted in gray) on the lateral tibial plateau of the right knee joint is viewed from the lateral side. The right side of the illustration is anterior to the knee joint, and the left side is posterior. This device is used to guide the Deschamps ligature carrier needle (depicted in green) accurately from the anatomic insertion site of the anteroinferior popliteomeniscal fascicle (iPMF) to that of the posterosuperior popliteomeniscal fascicle (sPMF). The Cattelan needle (TOP, Tokyo, Japan) is introduced from the insertion site of the sPMF and fixes the device to the LM while serving as a stopper that prevents the tip of the Deschamps needle from emerging from the femoral surface of the LM and as a slider that guides the tip of the Deschamps needle to the sPMF insertion. The other Cattelan needle is used to fix the guide to the LM. The popliteus tendon passes between the 2 Cattelan needles.

Method by which to pass the harvested iliotibial band (ITB) autograft through the lateral meniscus (LM) in a right knee joint as viewed from the lateral side. The right side of the illustration is anterior to the knee joint, and the left side is posterior. The LM is pierced with a Deschamps ligature carrier needle from the peripheral tibial rim of the LM at the anterior edge of the popliteus tendon (PT) to the peripheral femoral rim of the LM at the posterior edge of the PT. The open arrow indicates the direction of the force on the suture needed to keep the end of the harvested ITB in contact with the tip of the needle.

Anchor points for the anteroinferior popliteomeniscal fascicle (iPMF) and posterosuperior popliteomeniscal fascicle (sPMF) grafts on the popliteus tendon (PT) in a right knee joint as viewed from the lateral side. The right side of the illustration is anterior to the knee joint, and the left side is posterior. The distal part of the harvested iliotibial band (iPMF graft) is sutured temporarily to the PT 3 mm proximal to the tibial surface of the lateral meniscus (LM; shown as a black dot), and the proximal part of the harvested iliotibial band (sPMF graft) is sutured temporarily to the PT 8 mm proximal to the femoral surface of the LM (shown as a black dot). After all 4 verification criteria are checked, the ends of both the iPMF and sPMF grafts are sutured securely to the PT proximal to the locations of the temporary attachments.

5. Fig 4
Anteroinferior popliteomeniscal fascicle (iPMF) and posterosuperior popliteomeniscal fascicle (sPMF) grafts during arthroscopy after reconstruction of popliteomeniscal fascicles. (A) The patient is in the supine position with the right knee joint bent at 90° of flexion and adducted. With viewing of the lateral compartment of the right knee joint in an anteroposterior direction with the use of a 30° angled arthroscope through the anteromedial portal, the sPMF graft is shown in the expected position and does not intrude into the femoral surface of the lateral meniscus (LM). Undulation of the LM is not recognized. A superficial tear on the femoral surface of the LM around the hiatal portion was recognized before reconstruction of the popliteomeniscal fascicles. The probe is introduced through the anterolateral portal. (B) The patient is in the supine position with the right knee joint bent at 90° of flexion and adducted. With viewing of the lateral compartment of the right knee joint in an anteroposterior direction with the use of a 30° angled arthroscope through the anteromedial portal, the iPMF graft is shown in the expected position and does not intrude into the tibial surface of the LM. The probe is introduced through the anterolateral portal. (C) The patient is in the supine position with the right knee joint fully extended. With viewing around the hiatal portion of the LM in an anterolateral to posteromedial direction with the use of a 30° angled arthroscope through the midpatellar lateral portal, the insertions of the sPMF and iPMF grafts into the hiatal portion of the lateral meniscus are shown in their expected positions and do not intrude into the hiatal portion of the LM. (LFC, lateral femoral condyle; PT, popliteus tendon.)

6. Fig 5
Excursion of the popliteus tendon (PT) against the hiatal portion of the lateral meniscus (LM) throughout the range of motion of the knee joint. The excursion of the PT relative to the hiatal portion of the LM is measured with 90° of knee flexion as the starting position. A positive value for excursion indicates proximal migration of the PT relative to the LM, whereas a negative value indicates distal migration of the tendon. A nearly linear relation between the proximal excursion of the PT relative to the LM and knee joint angle was seen in 5 of 6 cases during flexion of the knee joints.
