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.

Article Synopsis
- Meniscal extrusion (ME) is a significant predictor of knee joint degeneration, but existing classifications primarily use numerical assessments without considering the underlying causes of ME.
- Evidence suggests that ME can arise from various conditions, including acute tears, chronic degeneration, and even joint loading or anatomical issues that are not necessarily indicative of pathology.
- A new qualitative classification is proposed to categorize ME into paraphysiological, pathological, and degenerative types, with an emphasis on adapting clinical management based on these distinct categories.
Purpose: The objective was to use cyclic tensile loading to compare the gap formation at suture site of three different suture materials to repair bovine radial meniscal tears: (1) polyglactin sutures, (2) tough adhesive puncture sealing (TAPS) sutures and (3) ultra-high molecular weight polyethylene (UHMWPE) sutures.
Methods: Twelve ex vivo bovine knees were dissected to retrieve the menisci. Complete radial tears were performed on 24 menisci, which were then separated into three groups and repaired using either pristine 2-0 polyglactin sutures, TAPS sutures (2-0 polyglactin sutures coated with adhesive chitosan/alginate hydrogels) or 2-0 UHMWPE sutures with a single stitch.

An incomplete discoid lateral meniscus is often associated with radial tears, which cause meniscal extrusion and result in poor healing outcomes. Centralization has recently been used as a surgical method to reduce extrusion. However, various repair techniques use single point of fixation sutures exclusively on the femoral side, potentially hindering healing.

Background: As the importance of meniscus in joint function becomes more apparent, there is a growing interest in meniscus repair techniques. Notably, biological augmentation methods have shown promising results for meniscus healing, despite their challenges in practical implementation. The purpose of this study was to evaluate meniscus healing and clinical outcomes of meniscus repair with bone marrow aspirate for horizontal or radial tears.

HCTs are a common tear pattern, especially as we age, and are estimated to occur in 23% to 32% of meniscus tears. They occur in both males and females, are more common on the medial than the lateral side, and most often occur with minor to normal trauma in an anterior cruciate ligament intact knee.
