Methods: We studied 148 patients (150 femoral shaft fractures) wi...

[ 12 ] - Intraarticular Injections of Platelet-rich Plasma (PRP)in the Management of Knee Osteoarthritis

The clinical use of PRP therapy in the practical setting of orthopaedic fields is increasing partly because of the accessibility of devices that are used in outpatient preparation and delivery. Another reason is the strong advertisement of PRP procedures as the ultimate treatment and novel technology for knee problems by a few orthopaedic surgeons based on claims of abundant scientific eviden...

[ 14 ] - 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...
