Inside-Out Bucket-Handle Meniscus Repair With a Single-Handed Self-Advancing Zone-Specific Meniscus Repair Device.

ABSTRACT: Meniscus tears are among the most common knee injuries in the general population and often are treated arthroscopically with a meniscus repair. Of the various meniscus repair techniques available, the inside-out meniscus tear is considered the gold standard due to its versatility and good clinical outcomes. The purpose of this Technical Note and accompanying video is to describe an inside-out bucket-handle meniscus repair using a single handed, self-advancing meniscus repair device with an interchangeable zone-specific multicannula system to decrease the technical difficulty and operative time of the repair.

Technique for All-Inside Repair of Bucket-Handle Meniscus Tears.

Project description:Bucket-handle meniscal tears (BHMT) remain a challenge to treat due to their complex pathology and technical difficulty. Subtotal meniscectomy has shown to improve symptoms early but leads to accelerated osteoarthritis in the affected compartment and poor long-term outcomes. BHMT repair and meniscal preservation is the preferred option. This can be performed with inside-out, all-inside, or hybrid meniscus repair techniques. All-inside meniscus repair avoids the need for additional safety incisions, trained assistants for suture passing, and reduce concerns of soft-tissue and neurovascular complications. In this Technical Note, we detail our all-inside technique for BHMT technique and share tips for a successful repair.

Arthroscopic Inside-Out Repair of a Meniscus Bucket-Handle Tear Augmented With Bone Marrow Aspirate Concentrate.

Project description:Bucket-handle tears of the meniscus comprise nearly 10% of all meniscus tears and commonly affect the young male population. Displacement of the free segment can lead to significant pain and disability, necessitating reduction and surgical treatment. General contraindications include malalignment, severe arthritis, significant comorbidities, or chronic asymptomatic tears, but otherwise repair should almost always be performed. Options for surgical treatment include partial meniscectomy and arthroscopic repair using an all-inside, outside-in, or inside-out technique. The purpose of this Technical Note is to detail our arthroscopic inside-out repair technique augmented with bone marrow aspirate concentrate.

Inside-out meniscus repair.

Project description:Meniscus repair over resection, when feasible, should be strongly considered in an effort to preserve meniscus integrity and function, especially in younger patients. Currently, a number of techniques and implants may be used to achieve a successful result. Although all-inside meniscus repair devices have evolved significantly since their introduction and have become the repair technique of choice for many surgeons, the classic inside-out repair technique is still very useful to have in one's armamentarium. Though less popular because of the ease of current-generation fixators, the inside-out technique can still offer advantages for those surgeons who are proficient. With the versatility to address most tear patterns, the ability to deliver sutures with smaller needle diameters, and proven long-term results, it has been considered the gold standard in meniscus repair. We review the inside-out repair technique for both a medial and lateral meniscus tear with some helpful tips when performing the technique, and we present a video demonstration of the lateral meniscus repair technique.

Inside-Out Repair for Radial Meniscus Tears.

Project description:Understanding of meniscal function through basic science, natural history, and biomechanics has highlighted the importance of preserving the meniscus to maintain normal knee biomechanics. Tears that may alter these biomechanics can contribute to the progressive nature of degenerative joint disease in the knee. Radial tears result in the disruption of the circumferential fibers causing inability of the native meniscus to resist normal hoop stresses, thereby leading to increased focal areas of pressure that cause complications such as early onset arthrosis. In this technical note, we describe our preferred operative technique to repair radial meniscal tears using an arthroscopic inside-out approach with satisfactory clinical outcomes and healing response.

All arthroscopic medial meniscus inside out repair- Technical note.

Project description:Concomitant meniscal injuries are common in patients with anterior cruciate ligament (ACL) insufficiency. Along with ACL reconstruction, meniscal repair offers better outcomes. This requires multiple incisions for both procedures. We present a novel technique of medial meniscus inside out repair using only the tibial tunnel wound without making an additional posteromedial incision. This is the first such description of this novel technique in a 21 year old male who underwent ACL reconstruction along with bucket handle medial meniscal repair.

The double ACL sign: An aberrant bucket-handle tear of lateral meniscus.

Project description:Introduction:Meniscal injuries are one of the most common musculoskeletal injuries around the knee affecting patients of different genders, ages and activity levels. These injuries could be acute or chronic tears that cause pain and mechanical symptoms based on the injury severity and whether it is displaced and entrapped in an abnormal location within the knee or not. Advances in magnetic resonance imaging (MRI) allowed us to have a better understanding of multiple bucket handle meniscal tear patterns with its specific MRI signs which have been reported in the literature. Case presentation:This report presents a rare case of a 16-year-old boy with atypical bucket-handle tear of lateral meniscus and MRI showed a bucket-handle tear of lateral meniscus with a fragment entrapped behind and parallel to the anterior cruciate ligament (ACL) appearing as another ACL in sagittal views. Meniscus was repaired arthroscopically. Conclusion:In our case, the unique and infrequent mechanism led to a bucket-handle tear involving lateral meniscus with a meniscal fragment entrapped in an unusual place intra-articularly behind ACL giving the appearance of a rare MRI sign "double ACL sign". However, double ACL sign secondary to lateral meniscal tear has been reported only once previously up to the authors' knowledge.

A suture technique for easier reduction and repair of bucket-handle meniscal tears while using the all-inside devices.

Project description:Arthroscopic repair of bucket-handle meniscal tears is difficult due to their complex pathology. Many meniscal repair techniques such as all-inside, inside-out, and outside-in have been described for the treatment of these tears. Loss of reduction is a likely complication with the use of new-generation, all-inside suture instruments, as the tip of the needle is extracted following advancement of the first implant behind the capsule. The complication may be encountered quite often and renders the use of the meniscus repair instrument unusable and causes an irreparable iatrogenic injury in the meniscus. The application of a simpler and more efficient technique is necessary until surgical experience is gained. The aim of this study was to define a new, simpler, and more efficient combination of suturing method in the treatment of bucket-handle meniscal repairs and minimize the rate of complications which may be caused by this technique.

Clinics in diagnostic imaging (177). Medical meniscus bucket-handle tear with medial oblique meniscomeniscal ligament.

Project description:A 29-year-old man with a previous football injury to his left knee presented with pain of the same knee. The patient twisted it as he was turning a corner quickly while going up the stairs, leading to internal rotation of his femur on his tibia with his knee in flexion. MR imaging revealed a bucket-handle tear of the medial meniscus, as well as a complete tear of the anterior cruciate ligament. However, image interpretation was complicated by the presence of a medial oblique meniscomeniscal ligament, a rare normal variant among intermeniscal ligaments of the knee. All four recognised variants of intermeniscal ligaments are discussed, with emphasis on their prevalence, imaging and anatomical features, and the way in which they may mimic meniscal tears.

Arthroscopic procedure for revision of failed isolated bucket-handle meniscal tear repair.

Project description:Surgery failure rates average 20% following bucket-handle meniscal tears (BHMT) repairs in the literature. Achieving the healing of BHMT is difficult, how much more in revision cases. Some authors have reported higher failure rates especially in the early postoperative period and in younger patients. Multiple techniques and augmentations to enhance biologic healing and reduce failure rate have been described. We describe an arthroscopic technique for successfully revising a failed BHMT repair using the technique of percutaneously releasing the posterior fibers of the medial collateral ligament to provide adequate space for arthroscopy, refreshing of the torn surfaces, bed trephination before reduction and repair. We concluded that a combined double-level inside out vertical sutures with horizontal reinforcement and all-inside technique using fast fix give anatomic reduction, stable fixation, surface contact, and increased potential for biologic healing in failed BHMT repairs. Coupled with adequate rehabilitation programs, this technique has reduced the failure rate in revision cases and enhances early return to sport.

Arthroscopic Repair for Parrot Beak Tear of Lateral Meniscus with Reduction Suture and Inside-Out 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.
