Popis: The purpose of this study was to determine the objective and subjective long-term outcomes of the first free meniscal allograft transplantations in five patients with complete absence or non-repairable lesion of the medial meniscus after 20 years. Between 1984 and 1986 five patients underwent concomitant medial meniscal transplantation with a deep frozen meniscal allograft, ACL reconstruction and femoral advancement or temporary detachment of the MCL. The clinical outcome of the patients was evaluated 20 years postoperatively using clinical assessment, Lysholm-score, KOOS, IKDC-score, radiographs and magnetic resonance imaging. The Lysholm-score ranged between 21 and 97 points of 100 maximal available points. Corresponding to this the total KOOS ranged between 28.4 and 91.1%. The results of the IKDC-score were evaluated as nearly normal (B) (n = 2), abnormal (C) (n = 2) and severely abnormal (D) (n = 1). The radiological evaluation according to the Kellgren-Lawrence classification showed an increase of the degenerative changes between one and four grades. The radiological results revealed clear degenerative changes with long-term follow-up after meniscal allograft transplantation even though some patients did relatively well regarding the subjective and clinical results in the 20-year follow-up examination in comparison with the literature. Despite these relative clear results the question if medial meniscal transplantation can protect against development of arthritis cannot definitely be answered because in this first case series some aspects of meniscus transplantation that have not been considered which turned out to be of importance during the last 20 years. Furthermore, it has to be taken into account that all patients revealed a cartilage damage at the time of surgery and an ACL reconstruction was performed in addition. Nevertheless from biomechanical point of view it might be taken into consideration to combine the medial meniscus transplantation at least with a high tibial osteotomy. Level of evidence was (IV, case series).
