Histologic fate of dermal grafts following implantation for temporomandibular joint meniscal perforation: a preliminary study

A study was carried out to evaluate the histologic changes of meniscus perforation repair associated with dermal grafts to the temporomandibular joint of cynomolgus monkeys (Macaca fascicularis) following surgical perforation of the meniscus. Dermal grafts were studied histologically at 3-week, 6-week, 3-month, and 6-month intervals. Results showed early attachment of the dermal graft to the meniscus, followed by gradual incorporation of the graft into the meniscus and subsequent return of the meniscal-graft complex to a normal meniscal architecture.
