Purpose : Recycling extracorporeal irradiated autograft is used as one of the reconstruction methods after limb salvage with malignant bone tumor. However, there were some problems such as joint instability, progressive arthritis, insufficient joint resection margin were found after intraarticular recycling autograft. Thus, we carried out a research in order to investigate the results of recycling total joint autotransplantation after extracorporeal irradiation that could resolve the problems.
Materials & Methods : There were five cases of patients who were diagnosed as osteosarcom around the knee joint and underwent same operation from June 1997 to Feb 2006. All patients had been evaluated from 93 to 105 months (mean 100 months) and their mean age was 21.6.
Results : The roentgenographic union of junctional sites began at 15.6 months (9~40 months) postoperatively. As regards to the orthopaedic functional results, we used the criteria of Ennecking et al. Overall mean functional result was 71.6%. Complication such as epiphyseal collapse (three cases) and joint instability (five cases) were noted respectively. In all the cases, tumor prosthesis was used to replace the knee joint.
Conclusion : Because recycling total joint autotransplantation after extracorporeal irradiation does not prevent joint instability and progressive arthritis, tumor prosthesis is recommended in young adult.
