Project description:Medial meniscus posterior root tears are common injuries, especially in the Asian world. This injury must be repaired where indicated to restore knee biomechanics and prevent arthritis. Suturing the meniscus using suture tapes provides good hold of the tissue. The use of a 70° arthroscope and creation of a transseptal portal improve visualization of the posterior compartment. Creation of a high posteromedial portal achieves the correct trajectory for the suture anchor insertion. A knotless suture anchor can be used to fix the posterior root at its anatomic attachment site. This obliterates the need for transtibial drilling for a suture pull-out repair or for knot tying and suture shuttling as for a conventional suture anchor.

Project description:The meniscal roots are critical in maintaining the normal shock absorbing function of the meniscus. If a meniscal root tear is left untreated, meniscal extrusion can occur rendering the meniscus nonfunctional resulting in degenerative arthritis. Two main repair techniques are described: (1) suture anchors (direct fixation) and (2) sutures pulled through a tibial tunnel (indirect fixation). Meniscal root repair using a suture anchor technique is technically challenging requiring a posterior portal and a curved suture passing device that can be difficult to manipulate within the knee. We present a technique for posterior medial meniscus root repair using 3 sutures (1 leader, 2 cinch), standard arthroscopy portals, and transtibial fixation. Overall, this technique simplifies a challenging procedure and allows for familiarity and efficiency.

Project description:Arthroscopic meniscus repair is one of the commonly used arthroscopic surgical procedures. Open treatment was the standard for meniscus repairs and recently arthroscopic all-inside treatment has become popular. Novel and more minimally invasive techniques to common arthroscopic procedures are paving the foundation to better patient outcomes. With the use of the NanoScope and nanoinstruments, we continue to develop new minimally invasive diagnostic and treatment techniques that do not require standard portals. The nanoscopic medial meniscus repair technique described here uses a less-invasive approach to a meniscus repair.

Project description:Medial meniscus posterior root tear is one of the underestimated knee injuries in terms of incidence. Despite its grave sequelae, using simple but effective technique can maintain the native knee joint longevity. In the current note, a 2-simple-suture pullout technique was used to effectively reduce the meniscus posterior root to its anatomic position. The success of the technique depended on proper tool selection as well as tibial tunnel direction that allowed easier root suturing and better suture tensioning, without inducing any iatrogenic articular cartilage injury or meniscal tissue loss. Using anterior knee arthroscopy portals, anterolateral as a viewing portal and anteromedial as a working portal, a 7-mm tibial tunnel starting at Gerdy tubercle and ending at the medial meniscus posterior root bed was created. The 2 simple sutures were retrieved through the tunnel and tensioned and secured over a 12-mm-diameter washer at the tibial tunnel outer orifice. Anatomic reduction of the medial meniscus posterior root tear was confirmed arthroscopically intraoperatively and radiologically by postoperative magnetic resonance imaging.

Project description:Medial meniscal root injury is known to cause an increase in tibiofemoral contact pressure and results in early osteoarthritis. There have been many reports on meniscal root repairing techniques, which can be categorized into 2 groups. One is transosseous suture, and the other is anchor suture repair. Both techniques show improvement in not only clinical performance, but also radiographic finding. However, the meniscal root repair procedure must be performed by experienced physicians. Most techniques require a posteromedial portal, which takes time and may even complicate the procedure. The technique proposed in this study provides a simple procedure in which no posteromedial portal is required and a soft anchor suture, a commonly used suture in glenolabral repair, is used. The use of this suture, instead of the conventional anchor suture, is believed to lessen possible injury to the cartilage and results in easier revision surgery.

Project description:Medial meniscal root tears are often disabling injuries that can occur in isolation during low-velocity, deep knee flexion maneuvers in middle-aged patients. The most common meniscal root tear pattern is a radial tear near the root attachment (type II). Root tears are often associated with meniscal extrusion, identified on magnetic resonance imaging. Relocation of the meniscal root to its anatomic center is a reported current difficulty faced by surgeons during surgical repair. However, this can be achieved via sufficient peripheral release of the posteromedial capsular attachment of the medial meniscus. The purpose of this Technical Note is to describe the authors' current surgical technique for medial meniscus root repair with a peripheral release for addressing meniscal extrusion. Classifications: level I (knee); level II (meniscus).

Project description:Improved understanding and treatment of posterior medial and lateral meniscus root tears have attracted increasing interest. These lesions significantly compromise meniscal function, which can result in an outcome resembling total meniscectomy, and are also a potential cause of knee instability. Despite facilitating repair procedures and reducing the operative time for these lesions, all-inside meniscal repair devices are not available in all circumstances or registered for use in all countries worldwide. Furthermore, all-inside arthroscopic devices can be expensive. Therefore, low-cost alternatives for the treatment of these lesions must be identified. We present 2 efficient and safe techniques: an outside-in technique for repairing medial meniscus root tears and a technique using a simple needle inserted through the transtibial tunnel for lateral meniscal root repairs, neither of which requires the use of specific instruments, thus enabling appropriate treatment of posterior medial and lateral meniscus root tears.

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:The medial meniscal root tear, a particular meniscal injury at the level of its posterior bone insertion, leads to a loss of impact absorption and load distribution capacity, similar to total meniscectomy. Therefore, its repair is fundamental for knee joint longevity. This type of injury often occurs in middle-aged patients with lower limbs varus malalignment, which results in mechanical overloading of the medial compartment and induces premature cartilage wear out. The success of meniscal root repair, with meniscal bone reinsertion, depends on the correction and realignment of varus deformities greater than 5° for physiological levels. In this situation, corrective tibial osteotomy combined with meniscal repair is indicated. Our goal is to describe the step-by-step technique of the valgus opening wedge tibial osteotomy combined with the arthroscopic reinsertion of the posterior meniscal root in tibia during the treatment of a patient with varus deformity and medial meniscus root tear.

Project description:Medial meniscus posterior root tear (MMPRT) is now attracting increased attention as a risk factor for the development of osteoarthritis. However, the healing rate after root repair by the suture anchor technique or the pull-out technique is still low. Here we report on a technique of MMPRT repair using suture anchor combined with arthroscopic meniscal centralization and open wedge high tibial osteotomy (OWHTO). The purposes of this technique are (1) to distribute the meniscal hoop tension between the root repair site and the centralization site and (2) to reduce the load on medial meniscus by OWHTO. The routine exposure for OWHTO with superficial medial collateral ligament release creates good visualization for arthroscopic root repair. The first anchor is inserted on the medial edge of the medial tibial plateau, and the second anchor is inserted on the root attachment through a posteromedial portal. After tying the knots, OWHTO could be performed without interference between the suture anchors and the screws of the plate for fixing the osteotomy. Although further follow-up is required, this technique could improve the outcomes after root repair, as well as have some technical advantages.
