title: CEMENTLESS ENDOPROSTHESIS IN THE TREATMENT OF GIANT CELL TUMOR OF THE TIBIA: EIGHTEEN YEARS OF EVOLUTION.
abstract: This is a case report on a giant cell tumor of the juxta-articular proximal tibia with a pathological fracture. A female patient presented pain and increased local volume after falling from her own height. She underwent clinical examination, radiographic examination and puncture biopsy. A diagnosis of giant cell tumor was made. The patient was then treated with tumor resection and use of an unconventional partial endoprosthesis of the tibia with preservation of the joint surface of the tibial plateau. The patient evolved with improvement of symptoms and maintenance of joint function of the operated limb, absence of recurrence and complications, without any need for reoperation over 18 years of follow-up.
