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 pr...

Meniscal root tears are defined as radial tears located within 1 cm from the meniscal attachment or a bony rootavulsion. This injury is biomechanically comparable to a total meniscectomy, leading to compromised hoop stressesresulting in decreased tibiofemoral contact area and increased contact pressures in the involved compartment.These changes are detrimental to the articular cartilage and ult...

Background: Meniscus tissue is highly susceptible to injury and tears. As these are intrasynovial and lack cellularity, their healing potential is less. Any knowledge to the factors affecting the meniscal healing can help surgeons in treating meniscal injuries. Hypothesis: Patient age is a predictor of the healing of meniscus tissue. Study Design: Prospective study. Methods: Gross and histologi...

BACKGROUND The restoration of damaged meniscus has always been a challenge due to its limited healing capacity. Recently, bone marrow-derived mesenchymal stem cells (BMSCs) provide a promising alternative to repair meniscal defects. However, BMSCs are not ideal chondroprogenitor cells for meniscus repair because they have a high propensity for cartilage hypertrophy and bone formation. Our hypot...

The discoid meniscus is probably a congenital deviation that usually occurs laterally. The Watanabe classification consists of complete, incomplete, or Wrisburg ligament types. Complete and incomplete discoid menisci normally require treatment only when a tear occurs. The Wrisburg ligament type lacks a posterior capsular attachment. The preferred treatment is repair of the posterior capsular di...

Background Extrusion of the meniscus has been reported to be correlated with progression of osteoarthritis. In cases with osteochondral lesions after extrusion of the meniscus, meniscal transplantation was the only surgical intervention. Recently, a novel procedure called arthroscopic centralisation has been developed to restore the meniscus function by centralising the midbody of the extruded ...

the basis of this paper has been planned on the functions of the meniscus and its effects. i.e. the existence of meniscus will prevent arthritis in other word torn-off (wholly meniscus and/or partly) will lead to suffering from arthritis. in view of the above, it is reasonable that attempt will be made to amend the torn meniscus instead of the surgical removal (meniscectom). the amendment may b...

BACKGROUND An avulsion of the posterior root attachment of the lateral meniscus or a radial tear close to the root attachment can lead to degenerative knee arthritis. Although the biomechanical effects of comparable injuries involving the medial meniscus have been studied, we are aware of no such study involving the lateral meniscus. We hypothesized that in situ pull-out suture repair of latera...

BACKGROUND Ultrasound techniques have been utilized for detection of discrete meniscus tears and extrusion. Meniscal extrusion is associated with increased contact pressure and decreased contact area contributing to the advancement of knee osteoarthritis. The purpose of this biomechanical study was to detect meniscal extrusion using a clinically available, portable ultrasound device. And furthe...

Damage to the medial meniscus root, for example by a complete radial tear, destroys the ability of the knee to withstand hoop strain, resulting in contact pressure increases and kinematic alterations. For these reasons, several techniques have been developed to repair the medial meniscus posterior root tear (MMPRT), many of which have shown complete healing of the repaired MMPRT. However, effor...
