Meniscal allograft transplantation for symptomatic knee after meniscectomy of torn discoid medial meniscus: Report of three cases

Abstract

In symptomatic discoid medial meniscus, partial meniscectomy is the principal treatment method andcan yield promising short-term results. However, unlike the nondiscoid meniscus, discoid medialmeniscus is frequently associated with horizontal cleavage tears, attributable to the presence of myxoiddegeneration in the intrameniscal substance, in that it may potentially occur deteriorating long-termresults because of re-tearing of remaining meniscus or secondary degeneration of cartilage of themedial compartment after meniscectomy. We experienced three rare cases of retear or secondarydegeneration of cartilage of the medial compartment after meniscectomy for two patients with tornbilateral meniscus. Both patients were highly active young males. Meniscal allograft transplantation incomplicated discoid medial meniscus was performed. At 2 years after meniscal allograft transplantation,clinical outcomes were improved with a normal range of motion. Orthopedic surgeons should recommend activity modiŞcation to prevent possible complicated injury of the discoid medial meniscus.Meniscal allograft transplantation may be an alternative option in highly active young patients undergoing complicated discoid medial meniscus to diminish pain, improve knee function, and prevent ordelay degeneration.© 2016 Turkish Association of Orthopaedics and Traumatology.
