This article aims to evaluate factors associated with chondral and meniscal lesions in primary and revision anterior cruciate ligament (ACL) reconstructions. ACL reconstructions from 2001 to 2008 at a single institution were retrospectively analyzed. Logistic regression was used to estimate the association between chondral and meniscal injuries and age, gender, tear chronicity, additional ligamentous injuries, sport type, and participation level. Of the 3,040 ACL reconstructions analyzed, 90.4% were primary reconstructions and 9...

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...

: Extracellular matrix (ECM) derived from decellularized tissues has been found to promote tissue neogenesis, most likely mediated by specific biochemical and physical signaling motifs that promote tissue-specific differentiation of progenitor cells. Decellularized ECM has been suggested to be efficacious for the repair of tissue injuries. However, decellularized meniscus contains a dense collagenous structure, which impedes cell seeding and infiltration and is not readily applicable for meniscus repair...

Meniscal injury is a common knee injury in a young athletic population. Maintaining the integrity of the meniscus is critical to reducing contact pressures on the tibiofemoral articulation. The purpose of this study is to analyze the outcomes of meniscal repair in a young military population. We conducted a retrospective review of all meniscal repairs performed on active duty Army personnel at a Military Medical Center from January 2002 to December 2012. One hundred seventy-eight active duty patients, mean age 28 (19-48) years underwent 178 meniscal repairs...

Decellularized scaffolds composed of extracellular matrix (ECM) hold promise for repair and regeneration of the meniscus, given the potential for ECM-based biomaterials to aid in stem cell recruitment, infiltration, and differentiation. The objectives of this study were to decellularize canine menisci in order to fabricate a micronized, ECM-derived scaffold, and to determine the cytocompatibility and repair potential of the scaffold ex vivo. Menisci were decellularized with a combination of physical agitation and chemical treatments...

BACKGROUND: The meniscus is known to increase the contact area and decrease contact pressure in the tibiofemoral compartments of the knee. Radial tears of the meniscal root attachment along with partial resections of the torn meniscal tissue decrease the contact area and increase pressure; however, there is a lack of information on the effects of a horizontal cleavage tear (HCT) and partial leaf meniscectomy of such tears on tibiofemoral contact pressure and contact area. METHODS: Twelve fresh-frozen human cadaveric knees were tested under 10 conditions: 5 serial conditions of posterior medial meniscectomy (intact meniscus, HCT, repaired HCT, inferior leaf resection, and resection of both inferior and superior leaves), each at 2 knee flexion angles (0° and 60°) under an 800-N axial load...

BACKGROUND: To evaluate the effects of suture site or penetration depth on anchor location in all-inside meniscal repair. METHODS: Eight fresh-frozen cadaveric knees were evaluated after meniscal repair using eight FasT-Fix360 (FF360) devices (Smith & Nephew Endoscopy, Andover, MA) (16 anchors) for each knee. The penetration depth was 14mm, the distance same from the periphery to insertion point, in four knees (Group A) and that in the remaining four knees (Group B) was 18mm...

BACKGROUND: This study aimed to consider the use of a meniscal repair in patients in order to close the horizontal cleavage extending up to the avascular zone. The hypothesis was to examine the clinical and arthroscopic outcomes following meniscal repair of degenerative horizontal cleavage tears with new-generation all-inside suture materials using the overlock method. METHODS: We retrospectively reviewed a consecutive series of 55 patients which had a horizontal pattern, and finally, 27 patients with a horizontal tear only which required no additional intra-articular surgical intervention were included in the study...

Arthroscopy is an important diagnostic procedure which can be used in rheumatology practice to provide direct visualization of the joint cavity, permitting macroscopic evaluation of the synovium, sampling for histopathologic and microbiologic examination and the potential therapeutic benefit of lavage. The term 'medical arthroscopy' is used here to refer to arthroscopy performed by rheumatologists for these purposes. This term differentiates arthroscopy performed by orthopedic surgeons for structural interventions such as meniscal debridement and ligament repair...

: Efforts have been made to engineer knee meniscus tissue for injury repair, yet most attempts have been unsuccessful. Creating a cell source that resembles the complex, heterogeneous phenotype of the meniscus cell remains difficult. Stem cell differentiation has been investigated, mainly using bone marrow mesenchymal cells and biochemical means for differentiation, resulting in no solution. Mechanical stimulation has been investigated to an extent with no conclusion. Here, we explore the potential for and effectiveness of mechanical stimulation to induce the meniscal phenotype in adipose-derived stromal cells...

The menisci play an important biomechanical role in axial load distribution of the knees by means of hoop strength, which is contingent on intact circumferentially oriented collagen fibers and meniscal root attachments. Disruption of the meniscal root attachments leads to altered biomechanics, resulting in progressive cartilage loss, osteoarthritis, and subchondral edema, with the potential for development of a subchondral insufficiency fracture. Identification of meniscal root tears at magnetic resonance (MR) imaging is crucial because new arthroscopic surgical techniques (transtibial pullout repair) have been developed to repair meniscal root tears and preserve the tibiofemoral cartilage of the knee...

PURPOSE: Treatment of meniscus tears is a persistent challenge in orthopedics. Although cell therapies have shown promise in promoting fibrocartilage formation in in vitro and preclinical studies, clinical application has been limited by the paucity of autologous tissue and the need for ex vivo cell expansion. Rapid dissociation of the free edges of the anterior and posterior meniscus with subsequent implantation in a meniscus lesion may overcome these limitations. The purpose of this study was to explore the effect of rapidly dissociated meniscus tissue in enhancing neotissue formation in a radial meniscus tear, as simulated in an in vitro explant model...

Complete radial tears of the medial meniscus significantly decrease the meniscal tissue's ability to dissipate tibiofemoral loads and have been described as functionally similar to a total meniscectomy, predisposing patients to early osteoarthritis. At present, no consensus exists regarding the optimal surgical treatment of a radial meniscal tear. Current repair techniques have led to a reportedly high rate of incomplete healing or healing of the meniscus in a nonanatomic, gapped position, which compromises its ability to withstand hoop stresses...

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...

A posterior horn of medial meniscal peripheral capsular is usually associated with the anterior cruciate ligament injury. The conventional repair technique with the camera in the anterolateral portal cannot precisely restore the slope capsular synovium to the original attachment point. We present the arthroscopic technique for improving the accuracy and quality of the repair by working in the posterior compartment. When the posterolateral portal is used as the viewing portal, the accuracy of repair is improved because we can assess the full extent of the lesion and lift the sagging peripheral tissue to the more central part...

Meniscal injuries are commonplace, but current surgical repair procedures do not prevent degenerative joint changes that occur after meniscal injury and often lead to osteoarthritis. Successful tissue regeneration in adults often recapitulates events that occur during embryogenesis, suggesting that understanding the regulatory pathways controlling these early processes may provide clues for developing strategies for tissue repair. While the mouse is now widely used to study joint diseases, detailed knowledge of the basic biology of murine meniscus is not readily available...
