BACKGROUND: Meniscal allograft transplant (MAT) is a salvage procedure for young patients with symptomatic meniscal deficiency. Although many studies report good outcomes, MAT remains controversial, and an optimal fixation technique for the meniscus roots is debated. PURPOSE: To assess the overall outcome of MAT and compare the results of different meniscal root fixation techniques. STUDY DESIGN: Meta-analysis. METHODS: Following specific guidelines, we systematically evaluated all current literature for studies reporting on the outcomes of patients who underwent MAT...

PURPOSE AND HYPOTHESIS: Post-operative weight bearing after meniscal repair is a point of debate among physicians. This study sought to evaluate whether patients adhering to an immediate WBAT rehabilitation programme have a higher failure rate compared to those adhering to a more traditional, protected, NWB status following meniscal repair. The null hypothesis was that there would be no difference in failure between the two groups. METHODS: A retrospective review of meniscal repair patients greater than 5 years from surgery was performed for patients receiving meniscal repair treatment...

BACKGROUND: Anterior cruciate ligament (ACL) tear is the most frequent injury in alpine ski racing, and there is a high prevalence of ACL reinjury. Limited data exist on the concurrent pathology with primary ACL tears in elite alpine ski racers and the magnitude of injury progression after primary ACL reconstruction (ACLR). PURPOSE: To evaluate (1) the involvement of intra-articular and multiligament pathologies at the time of primary ACLR, (2) the subsequent progression in meniscal/chondral injuries, and (3) the occurrence of ACL reinjury in elite alpine ski racers...

BACKGROUND: Clinical weightbearing provocation tests, like the duck walk test, may be of value in diagnosing or screening for medial meniscal tears. However, evidence of the diagnostic accuracy of the duck walk test is lacking. QUESTIONS/PURPOSES: (1) To determine the sensitivity and specificity of the duck walk test in diagnosing medial meniscal tears. (2) To determine whether tear location, tear cause (traumatic versus degenerative), and ACL insufficiency were associated with differences in the sensitivity and specificity of the test...

BACKGROUND: Meniscal tears can lead to significant pain and disability, necessitating surgical treatment. Nondisplaced vertical tears are usually smaller in size and can be repaired in most cases; however, bucket-handle tears are usually larger and displaced, and the repair of these tears can be challenging. Purpose/Hypothesis: The purpose was to report the outcomes after inside-out vertical mattress suture meniscal repair of bucket-handle tears and to compare these outcomes with those of patients who underwent repair of nondisplaced vertical meniscal tears with a minimum of 2 years' follow-up...

INTRODUCTION: Repair is indicated for tears in non-degenerative menisci. The literature reports a 15% failure rate for all-inside repair. The aim of the present study was to determine prognostic factors for failure of all-inside meniscal repair. The study hypothesis was that epidemiological, clinical and surgical factors affect success. MATERIALANDMETHODS: A retrospective study included 87 meniscal repair procedures, with or without anterior cruciate ligament (ACL) tear...

REVIEW
Jie Sun, Sanjairaj Vijayavenkataraman, Hang Liu
Current surgical treatments for meniscal tears suffer from subsequent degeneration of knee joints, limited donor organs and inconsistent post-treatment results. Three clinical scaffolds (Menaflex CMI, Actifit(®) scaffold and NUsurface(®) Meniscus Implant) are available on the market, but additional data are needed to properly evaluate their safety and effectiveness. Thus, many scaffold-based research activities have been done to develop new materials, structures and fabrication technologies to mimic native meniscus for cell attachment and subsequent tissue development, and restore functionalities of injured meniscus for long-term effects...

BACKGROUND: Quantitative magnetic resonance (qMR) can be used to measure macromolecules in tissues and is a potential method of observing early cartilage changes in the development of posttraumatic osteoarthritis. Hypothesis/Purpose: We hypothesized that specific patient and surgical factors affecting cartilage matrix composition after anterior cruciate ligament (ACL) reconstruction (ACLR) can be detected using T1ρ and T2 relaxation times. Our purpose was to demonstrate this ability in a multicenter feasibility study...

In this article, we present two middle-aged female patients with ulna fracture or medial meniscal tear resulting from dog-related injuries, which are not common. Both patients mentioned that pain started after their dogs pulled away their collar ropes strongly and suddenly. Both patients had postmenopausal osteoporosis and degenerative osteoarthritis. For this reason, ulna fracture and meniscus tear had developed with low-energy trauma resulting from dog-related injuries.

BACKGROUND: Injury or loss of the meniscus generally leads to degenerative osteoarthritic changes in the knee joint. However, the treatment options for symptomatic patients with total meniscectomy are limited. Therefore, we developed a novel, anatomically shaped, total meniscal implant made of polycarbonate urethane. PURPOSE: To evaluate the in vivo performance of this novel total meniscal implant. The assessment particularly focused on the implant's response to long-term physiological loading in a goat model and its chondroprotective capacity in comparison to clinically relevant controls...

PURPOSE: The purpose of this study was to compare the load-to-failure of different common suturing techniques with a new technique for the medial meniscus posterior root tear (MMPRT). METHODS: Thirty porcine medial menisci were randomly assigned to three suturing techniques used for transtibial pullout repair of the MMPRT (n = 10 per group). Three different meniscal suture configurations were studied: the two simple suture (TSS) technique, the conventional modified Mason-Allen suture (MMA) technique, and the new MMA technique using the FasT-Fix combined with the Ultrabraid (F-MMA)...

Tear of the meniscal root results in loss of circumferential hoop tension in the meniscus and increased tibiofemoral contact pressure, leading to cartilage wear. Repair of the meniscal root can restore function of the meniscus. Many techniques for root repair have recently been described. We present a technique for root repair using a transtibial socket and knotless suture technique that can be performed through standard arthroscopy portals.

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...

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...
