Distal femur fractures are often treated with laterally based plate constructs. The use of medial plates is less common because of the concern for the proximity to vascular structures. With a solid understanding of the anatomy, the technique can be used more frequently to optimize fixation in medial distal femur fractures and osteoporotic, comminuted, bone loss, and periprosthetic fractures. This video demonstrates a safe technique for the medial submuscular plating of a distal femur fracture. The video covers indications for surgery and provides detailed anatomy of the structures at risk, especially the superficial femoral artery system.

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.

Background: Studies have revealed abnormalities of the epiphyseal plate of the distal femur in patients with trochlear dysplasia, but it is unclear whether the epiphyseal plate could be remodeled after surgical correction of patellar dislocation.
Purpose: To investigate whether the morphology of the epiphyseal plate and trochlea could be improved after medial patellar retinaculum plasty in skeletally immature patients and to investigate the correlations between the morphology of the epiphyseal plate and trochlear dysplasia as well as clinical outcomes.
Study Design: Cohort study; Level of evidence, 3.
