Two separate new studies presented at a major medical meeting provide objective scientific evidence that the two most commonly performed cartilage repair techniques are effective at restoring patient mobility and reducing pain.
Patients in both studies, those that had a cartilage and bone grafts and those that had a procedure that encouraged new tissue growth, recovered more knee function and experienced less pain after the procedure. Prior to these results, surgeons had no evidence – apart from their own observations and experience – that these commonly practiced surgeries were effective. "The research conducted was a prospective analysis of randomly selected patients who sought treatment to repair cartilage damage. One study looked at patients who had osteochondral allograft, while the other followed-up with patients who had a microfracture procedure," said Riley Williams, MD, a co-author of the study and Director of the Hospital for Special Surgerys Institute for Cartilage Repair.
Dr. Williams added that the results of both studies will help doctors to more accurately predict outcomes for patients seeking relief from cartilage pain. Dr. Williams presented the research at American Academy of Orthopedic Surgeons (AAOS) annual meeting, February 23-26, 2005 in Washington, DC. The results of "The Microfracture Technique for Treatment of Articular Cartilage Lesions in the Knee: A Prospective Cohort Evaluation," were presented on Specialty Day, February 26th. "A Prospective Analysis of Knee Cartilage Defects Treated with Fresh Osteochondral Allografts," was on exhibit in a scientific poster throughout the event.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
