We described previously the use of undifferentiated autologous mesenchymal stem cells (MSCs) seeded onto a collagen scaffold (MSC/collagen-scaffold) to integrate meniscal tissues in vitro. Our objective was to translate this method into a cell therapy for patients with torn meniscus, with the long-...
The first thing to clarify is that the subgroup of people who volunteered to take part in this study did not experience an injury that resulted in an acute meniscus tear. Their meniscus damage was the result of wear and tear over a period of time. Second and more importantly, the fact is...
After an acute injury, you will almost always have to stop the activity you are doing, but you may be able to walk still. Other health problems can cause symptoms like those of an ACL injury, including a bone break or injuries to the meniscus and other ligaments in the knee. An ACL ...
Probe the inside of the knee and identify the area(s) of damaged meniscus. The surgeon will use this opportunity to check for other knee problems that might not be apparent from previous medical imaging, such as an MRI. Use special tools to smooth some of the edges of the damaged meniscus...

SMA has been found in a number of other healing connective tissues including skin, ligament, meniscus, cartilage, and other types of tendon. Of importance are previous findings that SMA-positive cells can contract a collagen-glycosaminoglycan analog of extracellular matrix in vitro. The results of ...

In the 3 patients who underwent second-look arthroscopy, complete healing was seen in 2 patients. One patient had severe degenerative changes in the meniscus; the repaired site was not united and required an additional partial meniscectomy along the tear. We believe that with the current ...
A posteroanterior flexion weight-bearing radiograph did not show any narrowing of the medial joint space. Considering the excellent healing observed in this case, preservation of the meniscus should be considered despite an association between a torn meniscus and an anomalous insertion....
Background: The collagen ultrastructure of torn medial meniscus posterior roots (MMPRs) has not been precisely defined. Purpose: To investigate the ultrastructure of torn MMPRs, focusing on their collagen fibers, and to compare the collagen net architecture between intact and torn MMPRs using the ...
