Repair of articular cartilage represents a significant clinical problem and although various new techniques - including the use of autologous chondrocytes - have been developed within the last century the clinical efficacy of these procedures is still discussed controversially. Although autologous chondrocyte transplantation (ACT) has been widely used with success, it has several inherent limitations, including its invasive nature and problems related to the use of the periosteal flap. To overcome these problems autologous chondrocytes transplantation combined with the use of biodegradable scaffolds has received wide attention. ⋯ Hyalograft C compares favorably with classic ACT and is particularly indicated in younger patients with single lesions. The graft can be implanted through a miniarthrotomy and needs no additional fixation with sutures except optional fibrin gluing at the defect borders. These results suggest that Hyalograft C is a valid alternative to ACT.

To re-assess the value of CT and clinical criteria as prognostic and severity indicators in acute pancreatitis and the correlation between them. ⋯ The predictive values of Ranson and PSI score in AP patients are superior to that of other criteria. CT criteria are superior to clinical criterion in predicting local complications, and short-term CT follow-up examination is important in the evaluation of AP.
