This study aimed to determine the incidence of meniscal tears and describe the tear morphology and selected treatment in patients undergoing anterior cruciate ligament (ACL) reconstruction. We also will discuss the potential market for future tissue engineering aimed at preserving meniscal function. A multicenter cohort of 1014 patients undergoing ACL reconstruction between January 2002 and Dec...

The meniscus plays a crucial role in maintaining knee joint homoeostasis. Meniscal lesions are relatively common in the knee joint and are typically categorized into various types. However, it is difficult for inner avascular meniscal lesions to self-heal. Untreated meniscal lesions lead to meniscal extrusions in the long-term and gradually trigger the development of knee osteoarthritis (OA). T...

BACKGROUND Meniscal repair in the setting of anterior cruciate ligament (ACL) reconstruction has demonstrated superior outcomes compared with isolated meniscal repair. Limited evidence exists for the effects of biological augmentation in isolated meniscal repair, particularly as compared with meniscal repair with concomitant ACL reconstruction. Purpose/Hypothesis: The purpose of this study was ...

Knee osteoarthritis (OA) after partial or total meniscectomy is a prevalent issue that patients must face. Various methods of replacing meniscal tissue have been studied to avoid this progression, including meniscal allograft transplantation, meniscal scaffolds, and synthetic meniscus replacement. Studies have shown that meniscal scaffolds may improve symptoms but have not been shown to prevent...

INTRODUCTION Calcium crystals exist in the knee joint fluid of up to 65% of osteoarthritis (OA) patients and the presence of these calcium crystals correlates with the radiographic evidence of hyaline cartilaginous degeneration. This study sought to examine calcium deposition in OA meniscus and to investigate OA meniscal cell-mediated calcium deposition. The hypothesis was that OA meniscal cell...

BACKGROUND Meniscal repair is commonly performed concurrently with anterior cruciate ligament reconstruction (ACLR) in the acutely injured knee. No large-scale, prospective multicenter studies have evaluated the long-term success and patient-oriented outcomes after combined ACLR and meniscal repair. PURPOSE To define the operative success and patient-oriented outcome scores 6 years after comb...

The integrity of the meniscal root insertions is fundamental to preserve correct knee kinematics and avoid degenerative changes of the knee. Injuries to the meniscal attachments can lead to meniscal extrusion, decreased contact surface, increased cartilage stress, and ultimately articular degeneration. Recent and well designed studies have clarified the anatomy and biomechanics of the medial an...

No single clinical examination element, or combination of such elements, reliably detects meniscal injury. The McMurray test is best for ruling in meniscal pathology. Assuming a 9% prevalence of meniscal tears among all knee injuries (a rate reflecting national primary care data), the posttest probability that a patient with McMurray’s sign has a meniscal injury ranges from <30% to 63% (strengt...

We report 2 cases of meniscal ganglion not associated with meniscal injury. The incidence of meniscal ganglion is reported to range from 1.4% to 3% among patients who have some injuries of the knee joint and underwent diagnostic tests or treatments including arthroscopy. Cases of meniscal ganglion not associated with meniscal injury as reported here are extremely rare. Treatment by partial meni...
