Arthroscopic surgery for the knee is one of the most common orthopedic procedures performed globally. Significant attention recently has focused on the role of arthroscopic surgery in the setting of osteoarthritis and its role in degenerative knee pathology. A number of recently performed randomized control trials and systematic reviews suggest limited benefit for arthroscopic surgery and partial meniscectomy for this indication. With this recent focus on arthroscopy use for osteoarthritis it is often forgotten that arthroscopy plays an important role in the management of other pathology involving the knee in patients who may have a concomitant diagnosis of osteoarthritis...

Preservation of the meniscus has been shown to influence the progression of degenerative changes of the knee. As more meniscus is preserved, the propensity for development of osteoarthritis is lessened. Surgical treatment of a torn discoid meniscus has typically been a subtotal meniscectomy or partial meniscectomy. Similar to tears of a normal meniscus, partial meniscectomy compared with subtotal meniscectomy of the discoid meniscus confers better long-term results. With the abnormal morphology predisposing the discoid meniscus to tearing, several characteristic tear patterns can be observed-the horizontal tear being commonly encountered...

Horizontal cleavage meniscus tears are a common orthopedic injury often treated with partial or total meniscectomy versus repair. This Technical Note presents a technique for all-inside repair with uniform compression of the superior and inferior leaflets by placement of multiple circumferential compression stitches using an all-inside self-retrieving suture passing device. The currently described technique provides several advantages for all-inside repair of a horizontal cleavage tear: (1) eliminates the need for a posterior incision, (2) minimizes the risk of neurovascular injury, (3) uses standard arthroscopy portals (or small modifications), and (4) requires only a single suture deployment with a self-retrieving device for each circumferential compression stitch...

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...

Lateral meniscus tears are commonly encountered by orthopaedic surgeons. Despite efforts to repair and preserve the meniscus, meniscectomy is occasionally required to treat irreparable tears. The resulting lateral meniscus deficiency leads to increased tibiofemoral contact pressures and ultimately early osteoarthritic changes in the knee. Lateral meniscal allograft transplant (LMAT) has been proposed as a way to restore the lateral meniscus-deficient knee to its native form. Although several techniques for LMAT have been proposed, osseous fixation has demonstrated increased stability, improved outcomes, and improved long-term survival...

BACKGROUND: Although thrombosis complication is rare after arthroscopic meniscus surgery, deep vein thrombosis and pulmonary embolism can be fatal. The associated risk factors and whether anticoagulant prevention after arthroscopic knee surgery is necessary have not reach consensus. Here we present a case of deep vein thrombosis and pulmonary embolism after a common arthroscopic meniscectomy. CASE PRESENTATION: The patient had no risk factors except ipsilateral leg varicose veins...

Magnetic resonance imaging (MRI) represents the preferred noninvasive imaging technique to diagnose meniscal pathology in the pre- and postoperative setting. Furthermore, characterization of meniscal tissue MR properties has been possible by the development of advanced MRI techniques. Suspected meniscal tears are a frequent indication for MRI and the International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) classification system has been developed to facilitate accurate and uniform reporting of such meniscal tears...

Background: Osteoarthritis (OA) is a degenerative joint disease characterized by progressive cartilage degeneration, subchondral bone changes, osteophyte formation, and synovitis. A major symptom is pain that is triggered by peripheral and central changes within the pain pathways. Some surgery-induced joint instability rat models of OA were described to mimic traumatic OA. Several behavioral tests were developed to access OA-induced pain. However, follow-up in most studies usually only occurred for about 4 weeks...

AIMS: Meniscal allograft transplantation is undertaken to improve pain and function in patients with a symptomatic meniscal deficient knee compartment. While case series have shown improvements in patient reported outcome measures (PROMs), its efficacy has not been rigorously evaluated. This study aimed to compare PROMs in patients having meniscal transplantation with those having personalized physiotherapy at 12 months. PATIENTS AND METHODS: A single-centre assessor-blinded, comprehensive cohort study, incorporating a pilot randomized controlled trial (RCT) was performed on patients with a symptomatic compartment of the knee in which a (sub)total meniscectomy had previously been performed...

OBJECTIVE: To assess the impact of osteoarthritis (OA) on the meniscus by comparing transcripts and biological processes in the meniscus between patients with and without OA. DESIGN: RNA microarrays were used to identify transcripts differentially expressed (DE) in meniscus obtained from 12 OA and 12 non-OA patients. The non-OA specimens were obtained at the time of arthroscopic partial meniscectomy (APM). Real-time PCR was performed on selected transcripts. Biological processes and gene-networking was examined computationally...

Degenerative meniscal tears (DMT) are common, often asymptomatic, and are associated with early-stage knee osteoarthritis in patients over 35 years of age. Conservative treatment, including exercise, physiotherapy and pain medication, should be offered as a first management approach for patients with symptomatic DMT. The indication for partial arthroscopic meniscectomy should be considered carefully, and based on specific criteria. Recently, several randomized controlled studies comparing partial medial meniscectomy to conservative treatment or to a sham procedure have questioned the effectiveness of surgical treatment of these lesions...

Meniscus tissues have limited regenerative capacity once damaged. The treatment options for the meniscus tissue regeneration have been limited to arthroscopic meniscectomy or surgical interventions. The injectable hydrogels based system would provide an alternative to the conventional meniscus therapy by providing a minimally invasive treatment alternative. Here we utilized enzyme-based approaches to fabricate tissue adhesive hydrogels for meniscus repair. Tyramine (TA) conjugated hyaluronic acid (TA-HA) and gelatin are susceptible to tyrosinase (TYR)-mediated crosslinking in vitro and in vivo...

BACKGROUND: Tissue excision in the setting of a meniscal tear has been shown to dramatically increase peak contact stresses in the affected tibiofemoral joint compartment, leading to the development of degenerative changes and osteoarthritis. PURPOSE/HYPOTHESIS: The current in vitro study utilized a porcine model to evaluate the effectiveness of segmental medial meniscal grafting following partial meniscectomy. The study hypothesis was that the procedure would normalize medial tibofemoral joint compartment pressure magnitudes, areas, and locations relative to an intact meniscus...
