Arthroscopic All-Inside Repair of Medial Meniscus Grade 2 Horizontal Cleavage Tear Using Additional Posteromedial Portal.

ABSTRACT: Management of intrasubstance horizontal cleavage meniscal lesions of microtraumatic origin remains poorly defined in young patients. For grade 2 lesions resistant to conservative measures, the standard technique is debridement of the intrasubstance tear and open suture repair via a posteromedial approach. The objective of this Technical Note is to propose an arthroscopic alternative to this open technique, using an arthroscopic additional posteromedial portal. This technique facilitates an approach to the lesion via its peripheral portion without creating an iatrogenic lesion of the free edge of the meniscus, which is located in the white zone and thus exhibits limited vascularity.

Project description:Arthroscopic repair of the posterior horn of the lateral meniscus (LM) from an anterolateral portal has a risk of popliteal artery injury. Here, we present an ultrasound-assisted, arthroscopic, all-inside repair technique for a posterior LM tear to reduce the risk of neurovascular injury. An ultrasound probe covered with a sterile sleeve is placed horizontally at the popliteal fossa by an assistant surgeon, and the popliteal artery and posterior LM are confirmed. From the anterolateral portal, an arthroscopic probe is inserted to push the posterior capsule of the lateral compartment, while an ultrasound image detects the tip of the probe. After the probe is confirmed not to be directed toward the popliteal artery, an all-inside suture device is introduced from the anterolateral portal. While the meniscus is penetrated, the surgeon can confirm by ultrasound images that the needle is directed away from the popliteal artery. The guide suture is pulled anteriorly to secure the anchors tightly, and an ultrasound confirms that the anchors are positioned behind the posterior portion of the LM. All sutures are secured under the assistance of ultrasound images, followed by arthroscopic confirmation of a properly secured LM by the all-inside repair technique. Technique Video Video 1 The arthroscopic view from the anterolateral portal shows a decreased volume of the lateral meniscus due to a previous surgical resection. The posterior lateral meniscus (LM) is pulled anteriorly over the center of the lateral compartment by probing. The posterior LM is repaired under the guidance of the ultrasound by having the assistant surgeon place the ultrasound probe, covered with a sterile sleeve, horizontally on the popliteal fossa to allow confirmation of the posterior portion of the LM and the popliteal artery. An all-inside suture device, the JuggerStitch, is introduced from an anterolateral portal, and the tip of the needle is observed in the ultrasound image. While penetrating the posterior LM, the direction of the needle is confirmed not to injure the neurovascular structures. The anchor of the JuggerStich is introduced at the posterior side of the LM and can be observed as a high echoic region. After introduction of two anchors, the sutures are pulled anteriorly through the anterolateral portal, and the knot is tightened. The ultrasound image shows that the two anchors are positioned on the capsule behind the posterior LM. The same procedures are then repeated. The location of the popliteal artery and the direction of the needle are confirmed by ultrasound every time. If the needle is directed toward the artery, it should be extracted and inserted again. A total of 4 sutures are performed to obtain stability of the LM under the assistance of ultrasound. The final arthroscopic examination shows the properly secured repair and the stabilized posterior LM by probing.
