Despite orientationally variant tears of the meniscus, suture repair is the current clinical gold treatment. However, inaccessible tears in company with re-tears susceptibility remain unresolved. To extend meniscal repair tools from the perspective of adhesion and regeneration, we design a dual functional biologic-released bioadhesive (S-PIL10) comprised of methacrylated silk fibroin crosslinked with phenylboronic acid-ionic liquid loading with growth factor TGF-β1, which integrates chemo-mechanical restoration with inner meniscal regeneration...

BACKGROUND: There is ongoing debate about the best way to manage ramp lesions at the time of anterior cruciate ligament (ACL) reconstruction (ACLR). Type 3 lesions are not visible by the transnotch approach without superior debridement, making the management debate even more problematic. PURPOSE/HYPOTHESIS: The purpose of this study was to evaluate the rate of secondary surgical interventions according to the management method of a type 3 ramp lesion concomitant with primary ACLR...

BACKGROUND: Despite the fact that meniscocapsular anterior detachment is the most common location of instability in children with a Discoid Lateral Meniscus (DLM), there is a lack of consensus about the type of repair that should be utilized for stabilization. The aim of this study was to determine the best fixation method for anterior detachment of DLM in children. Our hypothesis was that excessive rigidity with fixation would restrict meniscal mobility and increase the rate of failure or prevent full knee flexion...

Lateral meniscus hypermobility is a special condition in which the posterior horn of the lateral meniscus exhibits excessive mobility. This condition can cause pain and locking in the knee, especially during kneeling, deep flexion, or squatting. In this article, we present a surgical technique for the reinsertion of the posterior root of the external meniscus in cases of hypermobility without detachment. The objective is to increase the tension of the meniscotibial and meniscal popliteal ligaments to achieve meniscal stability...

Ramp lesions of the medial meniscus are underdiagnosed because of difficulty in visualizing via magnetic resonance imaging and during arthroscopy. They most often occur simultaneously with anterior cruciate ligament (ACL) injury but may also be associated with posterior plateau contusions, steeper medial tibial plateau slope, and excess varus alignment. Upwards of 24% of ACL reconstructions have concomitant ramp lesions. Failure to repair the ramp lesion is associated with increased rotational laxity, tibial translocation, persistent pivot shift, and poorer outcomes after ACL reconstruction...

Arthroscopic outside-in meniscal repair technique, which was first described by Warren in 1985, including all its later modifications, involved tying the final knot on the outer surface of the capsule. Capsular-side knot-tying has reported complications such as catching sensory nerves under the knot with resultant postoperative focal sensory loss and paresthesia, as well as pain under the skin because of irritation from the knot. Meniscus-side-knot-tying technique involves tying the knot on the outer surface of the meniscus...

Lateral meniscus posterior root tears (LMPRTs) are estimated to occur in 7% to 12% of anterior cruciate ligament (ACL)-injured knees. This topic is of great interest because of their biomechanical consequences in terms of interruption of hoop stress distribution. If left unrepaired, the corresponding compartment is exposed to unfavorable contact dynamics, similar to those resulting from a total meniscectomy. This Technical Note describes a transtibial LMPRT repair using a Knee Scorpion and an 18-gauge spinal needle...

Knee meniscus is the cushioning fibro-cartilage tissue present in between the femoral condyles and tibial plateau of knee joint. It is largely avascular in nature and suffers from a wide range of tears and injuries caused by accidents, trauma, active lifestyle of the populace and old age of individuals. Healing of meniscus is especially difficult due to their avascularity and hence requires invasive arthroscopic approaches such as surgical resection, suturing or implantation. Though various tissue engineering approaches are proposed for treatment of meniscus tears, 3D printing/bioprinting, injectable hydrogels and physical stimulation involving modalities are gaining forefront in the past decade...

BACKGROUND: Various suture configurations are available for medial meniscus posterior root tear (MMPRT) repair. The modified Mason-Allen (MMA) technique has been proposed as a refixation technique for MMPRT instead of the conventional 2 simple stitches (TSS). This is in view of its superior biomechanical characteristics. PURPOSE: To perform a systematic review and meta-analysis to compare MMA and TSS configuration techniques for MMPRT repair and identify any differences between the 2 techniques in terms of clinical outcomes, medial meniscal extrusion (MME), and postoperative healing...

PURPOSE: The aim of this study is to assess the dynamics of the tear site of meniscal ramp lesions, particularly considering knee flexion angles, and validate anchor fixation using an all-inside device. METHODS: Eight Thiel-embalmed paired cadaveric knees with their whole bodies were used in this study. The ramp lesions were created arthroscopically, and ramp lesion dynamics were evaluated by gradually extending the knee from 90° of knee flexion. Changes in the gap and step-off (0: no step-off; 1: cross-sectional overlap exists; and 2: tibial articular surface exposed) were evaluated at 90°, 60°, 30°, and 10° of knee flexion...

Meniscal root tears remain a common problem, with devastating biomechanical and clinical consequences. Thankfully, numerous techniques have been developed to repair the symptomatic meniscal root tear. However, rates of conversion to arthroplasty are reported to be 21% to 33% at 10 years, and persistent extrusion of the meniscus at follow-up is a known limitation of current root repair techniques. There is also growing evidence that some medial meniscal root tears may be an effect of meniscal extrusion, rather than the cause of it...

BACKGROUND: Meniscal repair is the gold standard for simple morphology tears. However, when the morphology and chronicity of the tear are less favorable, the success of the standard techniques is reduced. PURPOSE/HYPOTHESIS: To compare meniscal repair augmented by a new bioresorbable implant (Meniscus Cap) versus a traditional simple suture technique and the currently available augmented repair collagen matrix meniscus wrapping technique. It was hypothesized that the Meniscus Cap suture technique would increase ultimate failure load and less displacement during cyclic loading...

BACKGROUND: Meniscal injury is a common problem that can lead to knee pain and dysfunction. Meniscal repair and meniscectomy are two treatment approaches for meniscal injury, but the latter may increase the risk of osteoarthritis. We aimed to compare the 3-year outcomes of a new method of meniscal suturing with meniscectomy among patients with meniscal injury. METHODS: This retrospective cohort study compared meniscal repair (treatment group) and meniscectomy (control group) in patients with meniscal injury...

In the present study, 24 rabbits were firstly used to evaluate the apoptosis index and matrix degeneration after untreated adult meniscal tears. Vertical tears (0.25 cm in length) were prepared in the avascular zone of the anterior horn. Specimens were harvested at 1, 3, 6, 12 weeks postoperatively. The apoptosis index around tear sites stayed at a high level throughout the whole follow-up period. The depletion of glycosaminoglycans (GAG) and aggrecan at the tear site was observed, while the deposition of COL I and COL II was not affected, even at the last follow-up of 12 weeks after operation...

Medial meniscal root injury is known to cause an increase in the tibiofemoral contact pressure and results in early osteoarthritis. Several techniques have been described for transosseous suture repair. Typically, the sutures are passed through the meniscus, pulled out through a transtibial tunnel, and tied over a bone bridge, a suture button, or a screw at the anterior tibial cortex. Desired meniscus root tension may not be achieved in transosseous fixation with a suture button. The suspensory fixation technique is aimed to prevent secondary looseness in the knot attached to the button implant in the tibia and to provide the desired tension in the fixation of the button implant in different degrees of flexion of the knee...
