"Using PRP therapy to repair cartilage is still relatively experimental, but studies like this show it's not only safe but also offers a significant improvement in function and quality of life for patients," said Elizaveta Kon, MD, lead author for the study and Director of Nano-Biotecnology Laboratory at the Rizzoli Orthopaedic Institute in Bologna, Italy. "None of the patients treated experienced complications like infection, deep vein thrombosis or fever."
During the study, 180 patients were treated for chronic pain or swelling of the knee with either PRP therapy or viscosupplementation, a more common hyaluronic acid-based treatment for cartilage damage. A total of 109 patients, with an average age of 56, reached a final evaluation. Both treatment groups demonstrated significant improvement based on higher post-treatment IKDC scores, which measure pain and basic function in follow-up interviews.
"As athletic participation has grown," Kon noted, "new problems like cartilage lesions, or tears, continue to emerge. Finding the right approach to treatment is difficult, but PRP has emerged as a viable option according to our research."
Kon also noted that long-term follow-ups for PRP treatments are needed to further evaluate the overall effectiveness of the therapy for future patients.
The American Orthopaedic Society for Sports Medicine (AOSSM) is a world leader in sports medicine education, research, communication and fellowship, and includes national and international orthopaedic sports medicine leaders. The Society works closely with many other sports medicine specialists, including athletic trainers, physical therapists, family physicians, and others to improve the identification, prevention, treatment, and rehabilitation of sports injuries. AOSSM is also a founding partner of the STOP Sports Injuries campaign to prevent overuse and traumatic injuries in kids.

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
