Giant cell tumor (GCT) is among the commonest benign tumors and represents 5% of bone neoplasms. It is more common in young adults aged between 20 and 40 years. The distal femur is one of the most common sites, with the proximal tibia and distal radius the next frequently involved site, respectively. Previous research indicates that the tumor is an uncommon occurrence at this given age and location. Surgical management is the primary treatment for GCT universally. Extended curettage with the use of an argon beam cauterizer, a power burr, bone cement, hydrogen peroxide, phenol, liquid nitrogen, and zinc chloride are some of the treatment modalities for GCT. Opting for appropriate surgical treatments plays a crucial role to reduce the rate of recurrence and improve functional and oncological outcomes. In this case study, a 55-year-old male was diagnosed with GCT of the head of the right fibula with foot drop. The patient was managed with wide excision of the tumor and anchoring of lateral collateral ligament and biceps femoris to medial tibia condyle followed by postoperative galvanic stimulation for common peroneal nerve neuropraxia and guarded weight-bearing mobilization with bracing for knee joint. After 12 months of follow-up, there is no evidence of recurrence with a stable knee joint and dorsiflexion of the right ankle up to the neutral position.
