The meniscal healing process

Meniscus is a difficult structure to repair and replace. An injured or degenerative meniscus promotes osteoarthritic joint changes that should be avoided. Research focused on promoting healing or replacement must cover three different working lines: biology, mechanics and surgical technique. Biology research line looks for specific factors able to develop a collagen tissue in a matrix with cells that joins the edges of the lesion and also looks for factors able to keep the elasticity and able to regenerate the damaged meniscus fibres. On the other side, scaffolds need the adequate viscoelasticity to allow the penetration of vessels and cells to avoid reabsorption.
