New technique for knee flexion contracture with patella infera using patellar tendon reconstruction combined with anterior capsular shift: a case report.

A 24-year-old male presented with an open fracture of the left patella (Gustilo-Anderson grade III-A) and fracture of the left femoral lateral condyle, and subsequent patella alta suggesting rupture of the left patellar tendon. This initial injury was treated 6 months earlier in another hospital. He was referred because of limited knee motion and radiographs showed severe patella infera.

Transduction of anti-cell death protein FNK suppresses graft degeneration after autologous cylindrical osteochondral transplantation.

This study shows that artificial super antiapoptotic FNK protein fused with a protein transduction domain (PTD-FNK) maintains the quality of osteochondral transplant by preventing chondrocyte death. Cylindrical osteochondral grafts were obtained from enhanced green fluorescent protein (EGFP)-expressing transgenic rats, in which living chondrocytes express green fluorescence, and submerged into medium containing PTD-FNK, followed by transplantation into cartilage defects of wild-type rats by impact insertion simulating autologous transplantation. The tissues were histologically evaluated by hematoxylin-eosin and Safranin-O staining.
