all-inside meniscal repair

Radial tears of the human knee meniscus result in the loss of circumferential hoop stress and are highly correlated with knee degeneration. Although a variety of surgical techniques are available to repair radial meniscal tears, including inside-out, outside-in, and all-inside techniques, conventional repair techniques focus only on stabilizing the damaged portion. This Technical Note describes a biomechanical meniscus repair technique of meniscal circumferential fiber augmentation, concomitant with conventional repair, to promote meniscal healing from a biomechanical perspective...

Background Anterior cruciate ligament (ACL) injury is most common among athletes compared to the general population. ACL reconstruction is a clinical standard for restoring joint mechanical stability and enabling sports return. The purpose of the study is to evaluate the safety and functional outcomes after arthroscopic ACL reconstruction using the Sironix titanium button and the polyetheretherketone (PEEK) button. Methods A total of 31 subjects who have undergone arthroscopic ACL reconstruction using the Sironix titanium button and PEEK button between August 2022 and January 2023 were included in the study...

PURPOSE: To describe the clinical and radiographic features associated with isolated hypermobile lateral meniscus (HLM), and report patient outcomes following surgically repaired isolated HLM. METHODS: All patients diagnosed with HLM from 2000 to 2020 at a single academic institution were identified and reviewed. Patients were excluded if they had concomitant ligament injury or lacked 2-year follow-up. Preoperative and postoperative visual analog scale (VAS) pain scores were determined from clinical notes...

BACKGROUND/OBJECTIVE: For radial tears, all-inside suture (AIS) repair was clearly biomechanically superior, compared to conventional trans-capsular suture (TCS) repairs. However, clinical comparative studies of these two repairs techniques have not to be performed. Therefore, the aim of this study was to compare the clinical outcomes after AIS repair and TCS repairs for isolated radial tear at middle segment of lateral meniscus (RTMLM) in stable knees of young athletes. METHODS: Twenty-six athletes (mean age, 19...

BACKGROUND: One of the most important factors to consider in relation to meniscal repair is the high failure rate reported in the existing literature. AIM: To evaluate failure rates, return to sports (RTS) rate, clinical outcomes and magnetic resonance image (MRI) evaluation after meniscus suture repair for longitudinal tears at a minimum 2-year-follow-up. METHODS: We conducted a retrospective review of meniscal repairs between January 2004 and December 2018...

BACKGROUND: Segmental medial meniscal allograft transplantation (MAT) has been shown to restore knee biomechanics; however, stable fixation of the transplantation is critical to avoid extrusion and maximize healing. PURPOSE: To evaluate the degree of meniscal extrusion and biomechanical function of segmental medial MAT performed with meniscocapsular sutures versus repair augmentation with knotless suture anchors. STUDY DESIGN: Controlled laboratory study...

We present a convenient and safe arthroscopic technique for suturing the lateral meniscus. In this technique, the clinician establishes a conventional posteromedial approach in the figure-of-four position of the knee by using the anterolateral and anteromedial observation approaches. Behind the posterior cruciate ligament, an operational approach is formed through the posterior mediastinum of the knee joint. Through this approach, suture hook can be brought to the posterior horn and body of the lateral meniscus, thus simplifying the suture of the lateral meniscus...

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...

INTRODUCTION: The preferred management of medial meniscus tears has notably moved from meniscectomies towards repair. With a higher volume of meniscal repairs being done all across the world with every passing day, the lack of an objective and definitive sign suggesting the adequacy of its repair is daunting. The purpose of our study was to introduce a unique and novel arthroscopic sign formed after adequate repair of the medial meniscus, the AMR (Adequacy of Medial meniscus Repair) sign...

OBJECTIVE: To summarize the product registration declaration ideas and registration technical review of the all-inside meniscal suture system, and to systematically think about of the technical review concerns of the all-inside meniscal suture system products to provide technical guidance for improving the quality of registration and application and regulatory efficiency. METHODS: Consult the public information of such products at home and abroad, and summarize the experience of registration review of such products...

Introduction The meniscus plays an integral role in the proper functioning of the knee joint. Located between the articular surfaces of the tibia and femur, the meniscus functions to provide stability to the knee joint, even out axial load, absorb shock, and provide some lubrication to the knee joint. Accordingly, treatment of meniscal injuries aims to preserve as much meniscal tissue as possible to avoid the myriad complications that arise from its removal. This study of the all-inside technique for meniscal repair evaluates the University Hospital Southampton experience by comparing our outcomes with the available literature...

The benefits of preserving the meniscus are well-established. Several arthroscopic meniscal repair techniques have been described, such as the inside-out, outside-in, and all-inside. All-inside self-retrieving suture devices can be used to repair vertical, horizontal, and radial tears. However, this technique becomes difficult with large tears, as the jaw of the device cannot reach the peripheral edge of the meniscal tear. We present an all-inside technique using circumferential compression stitches to address large peripheral meniscus tears...

Meniscus root tears are tears that occur within 1 cm of the meniscus root attachment to the tibia. If not repaired, root tears will lead to altered knee biomechanics and accelerated degenerative changes in the knee. In this surgical technique, we demonstrate repair of a meniscus root tear with an all-inside suture repair of the posterior meniscus that is then passed through 2 transtibial tunnels and then fixed with an anchor. After surgery, patients are non-weightbearing for 4 weeks and can return to activity by 6 months...

We describe a combined all-inside, inside-out, and outside-in technique for the repair of unstable bucket-handle medial meniscal tears. Notably, a greater incidence of neurovascular complications has been associated with meniscal repair techniques that employ an accessory skin incision, especially when damage involves the body of the medial meniscus. However, with the operative knee in relative extension, passing inside-out needles anteromedial to the posterior horn and posterior to the semitendinosus tendon and saphenous nerve allows for the needles to exit the posteromedial knee through a "safe zone...

BACKGROUND: The role of meniscal lesions and repair in combination with anterior cruciate ligament (ACL) injury and reconstruction has not been extensively investigated in vivo and under weightbearing conditions. PURPOSE: The purposes of this study were to (1) compare the in vivo knee kinematics between patients with ACL tear and those with combined ACL and medial meniscal tears and (2) investigate kinematic differences between isolated ACL reconstruction and ACL reconstruction plus medial meniscal repair (MR)...

BACKGROUND: Medial meniscus posterior root tears (MMPRTs) disrupt the integrity and hoop tension of the meniscus, leading to cartilage degeneration and accelerated osteoarthritis (OA) progression. The management of patients with MMPRT is controversial, and the efficacy of different treatment options is unclear. PURPOSE: To compare the clinical, radiographic, and magnetic resonance imaging (MRI) outcomes of patients with MMPRT between trans-posterior cruciate ligament (trans-PCL) all-inside repair and partial meniscectomy...

BACKGROUND: The presence of a lateral meniscus root tear (LMRT) in patients with an anterior cruciate ligament (ACL) tear makes the knee more unstable and increases the risk of osteoarthritis and osteonecrosis. An all-inside suture repair technique without bone tunnels has been proposed to treat LMRT. PURPOSE: To compare the 1-year postoperative findings between patients who underwent ACL reconstruction combined with LMRT repair (LMRT group) and patients who underwent isolated ACL reconstruction (control group)...

BACKGROUND: Meniscus root tears are associated with chondral injury, early degenerative change, and a high conversion rate to total knee arthroplasty. It is well-established that meniscus root tears lead to decreased femorotibial contact area, increased peak contact pressures, and increased stress on the articular cartilage. PURPOSE: To evaluate the biomechanical characteristics of the all-inside meniscus root repair procedure and compare it with the previously described transtibial technique...

PURPOSE: To assess if incomplete meniscal healing during second-look arthroscopy at six to eight weeks after all-inside suture hook meniscus repair results in longer-term failure of repair in patients with restored knee stability. METHODS: From 2008 to 2013, 41 patients with post-traumatic, longitudinal, vertical, complete meniscal tears with concomitant ACL injury were treated via a two-stage surgical procedure and prospectively evaluated. In the first stage, all-inside meniscus repair was performed using suture hook passers and non-absorbable sutures...
