Arthroscopy-assisted treatment of giant cell tumor of the proximal femur: a case report

Giant cell tumor of bone (GCT) is a borderline primary bone tumor characterized by locally aggressive behavior, for which surgical management is the mainstay of treatment. Reports on GCT involving the proximal femur remain relatively limited. Achieving complete lesion removal while preserving hip joint function continues to represent a clinical challenge. A 25-year-old man presented with right hip pain. Imaging examinations revealed an occupying lesion in the proximal region of the right femur. The patient underwent lesion curettage and inactivation assisted by hip arthroscopy, followed by bone defect reconstruction using a combination of artificial bone and autologous bone grafting. This case suggests that arthroscopy-assisted lesion curettage combined with bone grafting may facilitate local tumor control while preserving hip joint function, and may serve as a reference for the management of similar cases.
