Inclusion criteria of the patients according to the tumor localization. Schematic illustration of a knee joint (lateral view). The patients were divided into 2 groups according the tumor localization. Patients with a superficially spreading lesion and no joint involvement were included in this study (indicated as number 1). If the tumor site is deep and involves the joint space (indicated as number 2) an extra-articular resection of the knee was performed.
