Abstract
Meniscal injuries are one of the most commonly encountered problems by orthopedic
surgeons today
Meniscal pathology in younger patients are likely to be consequent to an acute traumatic
event، while degenerative changes are more frequent at an old age
Magnetic resonance imaging (MRI) is the imaging modality of choice for diagnosis of
meniscal injury and is highly sensitive and specific for injury (1).However, the routine ordering of an
MRI scan of the knee before examination by a well-trained orthopedic surgeon is not recommended
Menisectomy was considered benign till the publication of king’s paper in 1936 which
reported the function of the semilunar cartilges and created awareness of the true importance of
menisciIn 1948, Fairbank reported the post- menisectomy radiological changes(4).
Meniscal repair was first described, in 1883, by Thomas Annandale
Initially, all meniscal repairs were performed through open techniques. However, arthroscopy
has become the gold standard
The indications for meniscal repair include vertical longitudinal tears in the outer 25%-30%of
the meniscus
Several biological strategies have been proposed to enhance healing of the avascular area of
the meniscus: abrasion therapy, fibrin clot, organ culture, cell therapy, and applications of growth
factors. However, data are too heterogeneous to achieve definitive conclusions on the use of these
techniques for routine management of meniscal lesions. Although most preclinical and clinical studies
are very promising, they are still at an experimental stage
Unfortunately, not all meniscus tears can be repaired, especially if considerable tissue
damage has occurred.(8) For several years, scientific researches have offered a solution for these
patients suffering from post-menisectomy syndrome, provided that the peripheral meniscal rim is still
intact and cartilage damage is limited. The treatment strategy is similar for the two implants available:
upon resection of the damaged tissue the resulting space is filled with a customized, synthetic, porous
material, which serves as ascaffold to regenerate meniscus-like tissue
