Abstract:
Objective To evaluate the mid-term(44 months) outcomes of meniscus allograft transplantation in four patients.Methods Between June and July 2005,four patients(3 medial and 1 lateral;3 men and 1 women;aged 21,27,35,38 years) underwent arthroscopy-assisted meniscus allograft transplantation in our hospital.The clinical outcome of the patients was evaluated by assessing the symptoms and signs,IKDC,Lysholm,and Tegner scores and examining the anteroposterior and lateral radiographs of the transplanted knee,weight-bearing radiographs of the both knees,anteroposterior radiographs of the lower extremities as well as magnetic resonance imaging(MRI).One patient underwent second-look arthroscopy. Results The follow-up time was 44-45 months.During the period,all the patients showed a normal motion range of the knee without pain or effusion of the knee joints.The mean IKDC,Lysholm,and Tegner scores of the patients were 84.75?2.63,91.50?4.43 and 7.00?0.82 respectively,which were significantly higher than those detected before the operation(60.50?14.06,69.25?22.04 and 4.00?0.82).The radiological results revealed no obvious degeneration or alignment changes though a 2-mm narrowing was shown in one of the patients.MRI showed mild extrusion for the body of the transplanted medial menisci and Ⅱ to Ⅲ stage signal for the body and the posterior horn.Almost normal performance and tension of the transplanted meniscus was shown by arthroscopy. Conclusions Meniscus allograft transplantation shows good outcomes in mid-term follow-up.MRI is valuable for evaluating the implanted meniscus.
