Free vascularized bone grafts from the medial femoral condyle have increasingly demonstrated utility in the successful treatment of challenging nonunions and bony defects. The consistent, robust vascular anatomy and the versatility to function as either a thin, flexible periosteal or corticoperiosteal graft or as a structural corticocancellous graft have made this graft a valuable option for addressing recalcitrant nonunions. The rationale, indications, vascular anatomy, and surgical technique of harvesting these grafts from the medial femoral condyle are presented.

Stress Analysis in Conversion Total Hip Arthroplasty: A Finite Element Analysis on Stem Length and Distal Screw Hole.
J Clin Med

Proximal femoral fractures are particularly common in older adults, and cases requiring conversion to total hip arthroplasty may arise because of treatment failure or osteoarthritis. Fractures around the distal screw removal holes can be problematic. This study aimed to analyze the relationship between stem length and femoral stress distribution to determine the optimal stem length.

Background: Osteochondral allograft transplantation (OCA) is well established as a viable chondral restoration procedure for the treatment of symptomatic, focal chondral defects of the knee. The efficacy of secondary OCA in the setting of failed index cartilage repair or restoration is poorly understood.
Purpose: To evaluate radiographic and clinical outcomes, failures, and reoperations after OCA after failed index cartilage repair or restoration of the knee.

Purpose Of The Study: Temporary hemiepiphyseodesis using figure-eight plates is currently one of the main surgical techniques to correct axial deformities of lower limbs in paediatric patients. Comprehensive analysis, correct indication and monitoring of treatment are the basic prerequisites for successful therapy. The aim of the study was to analyse parameters that could become an alternative to standard parameters used nowadays, namely the inserted screw angle (SA), and a new parameter - condylar ratio (CR).

Malignant mesenchymal tumors are a diverse group of aggressive cancers originating from mesenchymal cells in connective tissues such as bone, muscle, cartilage, and fat. These tumors often invade surrounding tissues and metastasize to distant organs, posing significant treatment challenges. Among them, malignant mesenchymal tumors located in the distal femur are particularly rare, with limited reports detailing effective surgical and functional reconstruction strategies following wide resection.
