Concurrent arthroscopic osteochondral lesion treatment and lateral ankle ligament repair has no substantial effect on the outcome of chronic lateral ankle instability.

Purpose: The purpose of the study was to evaluate the effect of concurrent arthroscopic osteochondral lesion (OCL) treatment and lateral ankle ligament repair on the outcome of chronic lateral ankle instability. It was hypothesized that the arthroscopic OCL treatment might have some negative effect on the outcome of chronic lateral ankle instability (CLAI) by compromising the rehabilitation program.

Methods: Ankle arthroscopy and anatomic lateral ankle ligament repair with suture anchors were performed for 70 patients with CLAI between 2010 and 2012.

Cell studies of hybridized carbon nanofibers containing bioactive glass nanoparticles using bone mesenchymal stromal cells.

Bone regeneration required suitable scaffolding materials to support the proliferation and osteogenic differentiation of bone-related cells. In this study, a kind of hybridized nanofibrous scaffold material (CNF/BG) was prepared by incorporating bioactive glass (BG) nanoparticles into carbon nanofibers (CNF) via the combination of BG sol-gel and polyacrylonitrile (PAN) electrospinning, followed by carbonization. Three types (49 s, 68 s and 86 s) of BG nanoparticles were incorporated.
