Optimization of Degradation Profile for New Scaffold in Cartilage Repair

Optimization of a Novel Scaffold for Cartilage Repair

A three-dimensional osteochondral composite scaffold for articular cartilage repair.

There is a recognized and urgent need for improved treatment of articular cartilage defects. Tissue engineering of cartilage using a cell-scaffold approach has demonstrated potential to offer an alternative and effective method for treating articular defects. We have developed a unique, heterogeneous, osteochondral scaffold using the TheriForm three-dimensional printing process. The material co...

Degradation and repair of articular cartilage.

Approximately 95,000 total knee replacements and 41,000 other surgical procedures to repair cartilaginous defects of the knee are performed annually in the United States (1). The response of normal articular cartilage to injury or arthritic degeneration is often a sub-optimal repair; the biochemical and mechanical properties of the new tissue differ from the native cartilage, resulting in inade...

New Frontiers for Cartilage Repair and Protection

OBJECTIVE Articular cartilage injury is common after athletic injury and remains a difficult treatment conundrum both for the surgeon and athlete. Although recent treatments for damage to articular cartilage have been successful in alleviating symptoms, more durable and complete, long-term articular surface restoration remains the unattained goal. In this article, we look at both new ways to pr...

The Role of Gene Therapy in Cartilage Repair

The key principle of gene delivery to articulations by direct intra-articular injection is to release complementary DNA(cDNA)-encoding medical products that will lead to maintained, endogenous production of the gene products withinthe articulation. In fact, this has been accomplished for both in vivo and ex vivo gene delivery, using several vectors,genes, and cells in some animal models. Some c...
