Abstract
|
|
|
Prosthetic reconstruction of musculoskeletal defects about the knee for tumor has many advan-tages,particularly the maintenance of motion and immediate functional restoration. But, prosthetic reconstruction has inherent limitations in terms of long-term durability. The authors have reported here a patient who had mechanical failure at 61 months later follwing use of a modular resection system to reconstruct the segmental defect of proximal tibia in osteosarco-ma. In this case,another technique of extensor mechanism reconstruction using Achilles tendon allo-graft was attempted.
Because of the concerns involving durability of tumor prosthesis,increased emphasis has to be placed on innovation in prosthetic design.
