Introduction: Giant Cell Tumors commonly occur around the knee joint in the age group of 20-30 years. They are treated with intra-lesional curettage or local resection and limb reconstruction. Management of large bone defects after resection is a challenge and is of ten complicated with non-union of grafts, infection and delayed weight bearing.
Case Presentation: A 37-year-old male presented with an aggressive recurrent giant cell tumor of the distal femur. He was and was diagnosed with a GCT of the left distal femur 2 years ago for which he was treated with an intralesional curettage and Poly methylmetacrylate implantation. A resection arthrodesis using a bilateral non-vascularised intramedullary fibular graft and a custom made intramedullary nail was performed. The follow-up radiographs showed union at graft-host junction and hypertrophy of the grafted fibula at 2 years post surgery.
Conclusion: Non-vascularised fibular graft is an effective alternative for resection arthrodesis with the advantages of a simpler and shorter surgical procedure and without the needs for a microsurgical setup.

Purpose: A finite element analysis was performed to simulate the biomechanical differences between anterior-posterior (AP) direction and posterior-anterior (PA) direction placement of two cannulated screws in Hoffa fractures.
Methods: Computed tomography images of an healthy male volunteer were used to simulate Letenneur Ⅰ, Ⅱa, Ⅱb, Ⅱc, Ⅲ Hoffa fractures, and two groups of screw internal fixation models were constructed. Two 6.

There is an increasing demand for a suitable bone substitute to replace current clinical gold standard autografts or allografts. Majority of previous studies have focused on the early effects of substitutes on bone formation, while information on their long-term efficacies remains limited. This study investigated the efficacies of natural hydroxyapatite (nHA) derived from oyster shells and synthetic hydroxyapatite mixed with collagen (COL/HA) or chitosan (CS/HA) on bone regeneration and implant fixation in sheep.

Osteotomies around the knee have a variety of indications, including pain reduction, functional improvement, knee joint stabilization, and articular cartilage preservation. Thorough preoperative planning is essential, including a determination of the precise location of any deformity (proximal tibia, distal femur, or both). High tibial osteotomies and distal femoral osteotomies can be performed in isolation, or jointly in the form of a double-level osteotomy, for correction of coronal and/or sagittal deformity of the knee.

Background: When patients with a failed hip arthroplasty are unsuitable for reimplantation, Girdlestone resection arthroplasty (GRA) is a viable treatment option. We report on a patient who was treated with a GRA due to a periprosthetic infection. We discovered partial paralysis of the quadriceps muscle in this patient.
