Abstract: | The purpose of this study was to examine the long-term clinical results of meniscus transplantation for articular cartilage
defects in the knee joint. The type of study was case series. From October 1990 to June 1995, eight cases underwent allogenic
or autogenic meniscus transplantations for articular cartilage defects, and seven cases were available for follow-up evaluations.
The age at surgery ranged from 14 to 42 years of age (average 22.5). In one case, transplantation of tissue-engineered cartilage
was performed due to pain 5 years after surgery. The other six cases were followed up for 8–13 years (average 10.1). The size
of the cartilage defect ranged from 1.0 to 6.3 cm2 (average 2.8 cm2). Patients were evaluated with the Lysholm score and MR images. We also performed arthroscopic examinations in three cases
at the final evaluation. This study leads to the conclusion that meniscus transplantation for articular cartilage damage is
not comparable to autologous chondrocyte transplantation. Two cases showed a good clinical outcome but the tissue remained
as fibrocartilage tissue in the long-term. |
