Any significant loss of meniscal function through injury or menisectomy alters the biomechanical and biological environment of the normal knee, eventually resulting in pain, recurrent swelling, and effusions. Overt secondary osteoarthritis is often the endpoint.1,2 Recognition of these consequences has led to a strong commitment within the orthopedic community to meniscal-sparing interventions....

INTRODUCTION The surgical repair of traumatic tears of the meniscus may enhance tissue remodeling, help to maintain the stability of the knee joint, and prevent osteoarthritic changes. After repair of the experimentally lacerated meniscus, treatment by intra-articular injections of hyaluronan (HA) has been shown to enhance meniscal remodeling [2]. HA treatment also appears to slow the degenerat...

BACKGROUND Reduced quadriceps strength influences knee function and increases the risk of knee osteoarthritis. Thus, it is of significant clinical relevance to precisely quantify strength deficits in patients with knee injuries. PURPOSE To evaluate isokinetic concentric quadriceps muscle strength torque values, assessed both from peak torque and at specific knee flexion joint angles, in patie...

Discoid meniscus is the commonest anatomical aberration of the knee joint, among rare cases such as bilateral separated lateral meniscus, accessory lateral meniscus, partial deficiency of the lateral meniscus and double-layered lateral meniscus. An 11-year-old girl presented with history of chronic pain in her right knee for the last 6 months. The problem disturbed her involvement in the sport ...

Meniscal lesions often occur in association with anterior cruciate ligament (ACL) tears at the moment of injury or, secondarily, as a consequence knee instability. Both ACL and meniscus are associated higher risk osteoarthritis. Adequate treatment these reduces rate degenerative changes affected knee. should be addressed concomitantly reconstruction must oriented towards preserving meniscal tis...

Meniscus cells have several distinct properties in cellular morphology and extracellular matrix production. Inner meniscus cells are considered to have more chondrocytic phenotype compared with outer meniscus cells. However, the chondrogenic property of each meniscus cell has not been elucidated in detail. In this study, we investigated the difference between human inner and outer meniscus-deri...

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 subtot...

The meniscus roots are critical for meniscus function in preserving correct knee kinematics and avoiding meniscus extrusion and, consequently, in the progression of osteoarthritis. Several techniques exist for medial meniscus posterior root tear repair; however, current surgical techniques have been proved to fail to reduce meniscus extrusion, which has been shown to be associated with developm...

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 o...
