Project description:Meniscal tears are commonly encountered conditions of the knee. In the past, torn menisci were treated by excision of the loose flap. A better understanding of the meniscus anatomy and its biomechanical characteristics has led to the concept of meniscus preservation in eligible cases. Several suture-based repair techniques have been described in literature, including the outside-in technique. Although the outside-in technique of meniscus repair is commonly indicated for the anterior two-thirds of the meniscus, it can be used to repair the posterior part of the meniscus as well. Several modifications of this technique have been described in the literature. We hereby describe our modification of the outside-in technique of meniscus repair with the help of an epidural needle and high-strength sutures that is readily available in operating rooms. The advantages of our technique are that no large incision is required around knee joint, it's inexpensive, it can be performed with basic instruments, and even the tear of meniscus extending up to the posterior horn can be repaired. A supplemental video demonstration of the technique is included with this article.

Project description:Radial meniscus tears occur commonly as traumatic tears in younger patients, as well as in association with concomitant degenerative changes. Traditional management of these tears has centered around partial meniscectomy; however, there has been a more recent trend toward preserving the meniscus and attempting repair. Because of the gapping and displacement that frequently occurs with these tears, repair is often challenging and is done under high amounts of tension. The following article describes a technique using a traction suture to aid in maintaining reduction throughout repair. This is followed by the use of a combination of techniques to form a “super-hashtag” configuration of both vertical and horizontal mattress sutures, leading to a secure repair under little tension. Technique Video Video 1 Video demonstrating technique for repair of anterolateral radial meniscus tears using a traction suture and super-hashtag orientation. This video shows arthroscopic view from the anterolateral portal with the lateral femoral condyle at the top of the view, and the lateral tibial plateau at the bottom. A standard diagnostic arthroscopy is then performed. The video first demonstrates the identification of the tear at the junction of anterior and middle thirds of the lateral meniscus, which includes a large amount of gapping. A rasp is then used to abrade the synovium and tear to generate the best biologic healing response. The traction suture is then placed in the posterior limb of the tear with the use of the NovoStitch Pro Meniscal Repair System (Smith & Nephew, Andover, MA). This is performed by making one bite in the periphery of this limb, followed by another more centrally. Suture limbs are then brought out through the lateral portal to be used to pull traction and maintain reduction of the tear throughout the remainder of the repair. The anterior and posterior limbs are then secured to the capsule in reduced position with the use of vertical mattress sutures via a combination of all-inside, inside-out, and outside-in techniques. The same sutures are then used for tie-grip or rip-stop sutures for the horizontal mattress. The sutures are tied under the iliotibial band and directly at the capsule, while keeping the meniscus reduced with the traction suture. This is followed by placement of various horizontal mattress sutures over the tie-grip or rip-stop sutures, creating a “super-hashtag” repair. Our postoperative protocol includes keeping the patient non-weightbearing for 6 weeks following surgery with hinged knee brace locked in extension for the first 2 weeks. Range of motion will be strictly 0-90° for the first 4 weeks. Deep vein thrombosis prophylaxis is continued for 6 weeks postoperatively.

Project description:Arthroscopic suture repair for a radial tear at the posterior horn of the lateral meniscus poses a technical procedure for surgeons. We describe an all-inside repair technique using all-inside meniscal repair devices without adding any accessory portals. This simple technique provides precise reduction and stabilization of the meniscus by pinching 2 all-inside vertical sutures consecutively across the tear site.

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.

Project description:Complete radial tears of the medial meniscus significantly decrease the meniscal tissue's ability to dissipate tibiofemoral loads and have been described as functionally similar to a total meniscectomy, predisposing patients to early osteoarthritis. At present, no consensus exists regarding the optimal surgical treatment of a radial meniscal tear. Current repair techniques have led to a reportedly high rate of incomplete healing or healing of the meniscus in a nonanatomic, gapped position, which compromises its ability to withstand hoop stresses. Improvement regarding the ability to repair and heal medial meniscus radial tears has the potential to result in enhanced preservation of the articular cartilage in the medial compartment of the knee. This technical description details a method for repairing radial tears of the medial meniscus using a transtibial 2-tunnel technique.

Project description:Parrot beak tear is a white-white meniscal injury that often occurs in isolated injuries. Partial meniscectomy for parrot beak tears is often recommended, owing to the avascular zone; however, partial meniscectomy, especially with the lateral meniscus, has a high failure rate for return to sports, leading to residual meniscus extrusion and lateral compartment osteoarthritis. Thus, we have developed a repair technique to preserve the parrot beak tear of the avascular zone. This is a modification of the inside-out repair with additional reduction sutures. We recommend this procedure as a technique for repairing avascular parrot beak tears of the lateral meniscus.

Project description:With improvement in arthroscopic techniques, partial meniscectomy with repair for symptomatic discoid lateral meniscus (DLM) has been the preferred treatment to restore meniscal function. It was reported that DLM exhibited deformation and extrusion shortly after saucerization with repair. Therefore it is desirable to minimize removal of the DLM. The anterior zone of the DLM is often tighter than that of the normal meniscus and anatomic variant. It is considered that the anterior and anterocentral dislocation types in the majority of symptomatic DLM can be related to both peripheral instability and anterior tightness. We present a technique that, first, the inside-out repair technique is applied from the posterior to middle segment of the DLM; next, the tension of the anterior zone during knee flexion-extension is confirmed to determine the released amount of that part; and, finally, all sutures are tied to reproduce the normal meniscus movement. Meniscus repair with anterior cord release without any meniscectomy could resolve peripheral instability of DLM and prevent degeneration of the articular cartilage.

Project description:Double radial tears of the lateral meniscus are rare injuries that typically occur in the setting of an acute anterior cruciate ligament rupture. Full-thickness radial tears of the meniscus body and root render the meniscus nonfunctional from a loss of hoop stress resistance. Repair of these tears can normalize contact pressures in the lateral compartment and delay arthritic changes. We describe our technique for repairing a lateral meniscus body radial tear and concomitant posterior root tear, via inside-out suture repair and transtibial suture repair, respectively. This investigation was performed at Mayo Clinic.

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.

Project description:Lateral meniscus lesions result in loss of meniscus hoop stresses and can lead to lateral compartment overload and early degenerative changes. Arthroscopic suture repair provides good long-term results. However, posterior vertical tears in the peripheral area of the meniscus can be technically challenging to resolve. This Technical Note describes the suture hook technique using an accessory posterolateral portal. We believe it is a safe, effective method for repairing full vertical tears of the lateral meniscus.
