Subtracting–adding strategy for necrotic lesion segmentation in osteonecrosis of the femoral head
Osteonecrosis of the femoral head (ONFH) is a severe bone disease that can progressively lead to hip dysfunction. Accurately segmenting the necrotic lesion helps in diagnosing and treating ONFH. This paper aim...

A Time-Dependent Design Concept of a Cementless Hip Stem Prosthesis for Improving Physiological Load Transfer in Proximal Femur: A Finite Element Analysis
Although short-stem prostheses have been introduced to improve metaphyseal load transmission, the shortcomings of short-stem total hip arthroplasties (THAs) such as early axial migration, lower load bearing, a...

Open AccessA novel protection liner to improve graft-tunnel interaction following anterior cruciate ligament reconstruction: a finite element analysis
Deteriorated bone-graft interaction at the tunnel entrance following ACL reconstruction (ACLR) is considered one of the primary causes of long-term tunnel enlargement and graft wear. Methods have been introduc...
