From September 1996 to September 1997, 27 adult patients were diagnosed with chronic triangular fibrocartilage complex (TFCC) tears with distal radioulna joint (DRUJ) instability in our clinic. They all received the procedure of TFCC reconstruction with partial extensor carpi ulnaris (ECU) tendon combined with or without ulnar shortening. There were 26 males and one female in the study with a m...

OBJECTIVE We report the long-term clinical outcomes of patients who underwent autogenous bone grafting of large-volume osteochondral defects of the knee due to osteochondritis dessicans (OCD) and osteonecrosis (ON). This is the companion report to one previous published on the biological response. We hypothesized that these grafts would integrate with host bone and the articular surface would f...

INTRODUCTION The aim of this study was to determine the association between individual quadriceps muscle volumes and the quadriceps enthesis structures and cartilage morphology at the patellofemoral joint (PFJ). METHODS We studied 12 cadavers (age 75 ± 5 years). For both legs, individual quadriceps muscles (vastus lateralis (VL), rectus femoris (RF), vastus intermedialis (VI) and vastus media...

Cartilage is a dense connective tissue with limited self-repair capabilities. Mesenchymal stem cell (MSC) laden hydrogels are commonly used for fibrocartilage and articular cartilage tissue engineering, however they typically lack the mechanical integrity for implantation into high load bearing environments. This has led to increased interested in 3D bioprinting of cell laden hydrogel bioinks r...
