All-inside Techniques for Meniscal Radial Root Tear Repair.

ABSTRACT: Meniscal radial root tears can disrupt the load-bearing function of the meniscus and worsen instability in anterior cruciate ligament-deficient knees. Paracentral radial tears adjacent to the root (types 1, 2, and 4) repaired with a transtibial pullout suture technique can lead to over-medialization of the meniscal root and a high-tension nonanatomic repair. We propose 2 all-inside techniques for anatomic repair of medial and lateral meniscal radial root tears with (1) an all-inside meniscal repair device and (2) an antegrade suture passer. We present the technical requirements and tips for these techniques. For lateral meniscal radial root repair with an all-inside meniscal repair device, ideal viewing is from an anterolateral portal with device entry from an anteromedial portal to reduce the risk of vascular injury. We recommend at least 2 stitches across the tear, with the depth setting limited to 18 to 20 mm for a central stitch and 16 mm or less for a peripherally placed stitch. For root repair with an antegrade suture passer, viewing should be from an anteromedial portal with the passer entering from an anterolateral portal. At least 2 stitches should be placed across the tear, with 1 central and 1 peripheral or 1 superior and 1 inferior.

Horizontal Cleavage Tear Meniscal Repair Using All-Inside Circumferential Compression Sutures

Project description:Horizontal cleavage meniscus tears occur more frequently in older patient populations with degenerative changes within the meniscus. Traditionally, they have been managed with nonsurgical interventions or with partial meniscectomy. As increasing evidence demonstrates the link between partial meniscectomy and progressive osteoarthritis with these types of tears, as well as worse long-term outcomes and reduced cost savings, surgical repair of horizontal cleavage meniscal tears has increased in appropriate patients. This technique article highlights the evaluation, indications, and preferred repair technique for horizontal cleavage tears in appropriately selected patients. Technique Video Video 1 Demonstration of technique. The patient is placed in the supine position. A superolateral outflow portal is placed to allow for adequate intra-articular visualization followed by the creation of standard anteromedial and anterolateral portals. Initial diagnostic arthroscopy is performed viewing from the anterolateral portal. Once the tear has been identified, the meniscal tear is further visualized by preparation of the frayed edges with a combination of meniscal rasping, biting, and shaving. Following preparation, the meniscal repair is begun posteriorly working from the anteromedial portal to allow for direct access to the meniscus. In this case, the tear is of the medial meniscus. If the medial compartment is tight, prohibiting sufficient access, percutaneous trephination of the medial collateral ligament is performed to increase access. Using the Smith & Nephew NovoStitch Pro All-inside device, circumferential compression sutures are placed 3 to 4 mm apart working from posterior to anterior. At the mid-body of the meniscus, the working portal is switched to the anterolateral portal to allow for more direct access to the remainder of the more anterior portions of the meniscus.

Continuous Meniscal Suture in Radial Meniscal Tear: The Hourglass Technique.

Project description:The key to preventing early knee osteoarthritis is meniscal preservation. The main functions of the meniscus are impact absorption, mechanical load transmission, lubrication, joint stability, and proprioception. Radial lesions that extend to the joint capsule are called complete radial tears. This type of injury compromises 2 of the main meniscal functions, which are impact absorption and load distribution, which is equivalent, from a biomechanical perspective, to a total meniscectomy. In the recent past, the treatment of choice for this type of injury was partial meniscectomy. However, several studies have observed progressive joint degeneration after this type of treatment. Recently, different types of meniscal sutures involving radial lesions of the meniscus have been developed. It is believed that such repairs may bring a decrease in future osteoarthritis in this patient profile. The purpose of this article is to describe the steps of continuous meniscal suture for the treatment of radial tears of the medial and lateral menisci.

Full-Thickness Radial Medial Meniscal Tear: Fixation With Inside-Out Technique With Tibial Knotless Suture Anchors.

Project description:Complete radial tears of the meniscus render the entirety of the meniscus functionally incompetent (known as an ameniscal state); therefore, attempts at repair are essential. Although various techniques have been described, repair failures continue to frequently occur, especially with the medial meniscus. Inside-out repair and anchoring of the preserved meniscus to both the capsule and tibia may offer the advantage of a more robust repair. The objective of this Technical Note is to describe a method of repair for complete radial tears of the medial meniscus using a combination of inside-out sutures and secondary reinforcement to the tibia using all-suture knotless anchors.

Meniscus Root Tear: Extended Classification and Arthroscopic Repair Techniques.

Project description:The meniscus root is an attachment of the anterior and posterior horns of the meniscus onto the tibia, and its primary function is to prevent extrusion under axial load. Meniscus root tear constitutes 15% to 20% of meniscus tear. With the increased incidence of root tears being diagnosed commonly, many newer morphologic patterns of root tears have been detected, and the need to extend the conventional classification arises. At the same time, preserving the meniscus root necessitates novel techniques to repair this newer pattern. In this Technical Note, we describe the extended classification of root tears and arthroscopic repair techniques to achieve stable and secure fixation of meniscus roots.

An Arthroscopic-Assisted Radial Meniscal Tear Repair Using Reinforced Suture Tape Rebars and Suture Tapes.

Project description:A radial tear of the meniscus can lead to significant loss of meniscus function, resulting in deleterious cartilage changes. Repair of radial meniscus tears has several challenges, including suture pull-out, which can reduce healing success. We present an arthroscopic repair technique in a complete radial lateral meniscus tear using vertical reinforced bars (rebar) of suture tapes to reduce suture pull-out and approximate the radial tear.

All-inside arthroscopic meniscal repair with meniscal cinch.

Project description:The number of commercially available all-arthroscopic meniscal repair devices has increased in recent years. Although inside-out vertical mattress sutures have been considered the gold standard in the past, recent biomechanical studies have shown that some all-arthroscopic repair devices provide comparable strength. To successfully use these devices, surgeons must understand proper insertion technique. The purpose of this article is to demonstrate this technique for the Meniscal Cinch (Arthrex, Naples, FL).

Transtibial Pull-Out Repair of Converted Radial Tear Adjacent to Medial Meniscus Root.

Project description:Radial tears increase tibiofemoral contact pressure and disrupt the ability of the meniscus to withstand hoop stress, leading to earlier-onset osteoarthritis. Repair of radial tears is problematic because they have a lower healing rate and lack a single gold standard technique. However, when a radial tear is proximal to the root, there is an opportunity to convert it into a root tear. This is ideal because root tears fixed through a transtibial tunnel technique have improved clinical outcomes and reduced rates of osteoarthritis. This Technical Note and accompanying video describe a method for repairing a radial tear near the meniscus root by converting a radial tear to a root tear followed by a pull-out root repair through a transtibial tunnel. This method restores the meniscus root, allowing it to withstand hoop stress. Our technique uses a disposable root repair kit that includes a FlipCutter, a Knee Scorpion Suture Passer, a 4.75-mm SwiveLock anchor tap, a SutureLasso, a PassPort Cannula, 0 FiberLink sutures, and TigerLink sutures.

Posterior Meniscal Root Repair Using a Meniscal Suture Device.

Project description:A greater understanding of the deleterious consequences that a meniscal root tear brings to the knee joint and how its surgical repair can be advantageous over the previously used treatment strategies brings the need for the development of surgical techniques that make the procedure less complex and more reproducible. When meniscal root rupture occurs, a mechanical overload occurs in the affected compartment similar to a total meniscectomy. Several authors have concluded that meniscal root reinsertion significantly improves postoperative outcomes and patient satisfaction, regardless of age or laterality of the meniscal injury. The Meniscus 4 A-II device (Rio de Janeiro, Brazil) allows stitching at the root of the medial and lateral menisci. In this article, we describe the surgical repair technique for posterior-medial and -lateral meniscal root tears using this meniscal suture device. This technique is fast and effective.
