New discovery can increase the lifespan of donated bone and cartilage

28 January

A new method has been developed that could allow surgeons to use more donated tissue to repair joint problems. At present, over 80 per cent of all donated join tissue has to be discarded because it cannot be properly preserved until the time of surgery.

Researchers at the University of Missouri School of Medicine have invented the Missouri Osteochondral Allograft Preservation System (MOPS) to double the usable life of donated bone and cartilage. It involves using an innovative preservation solution and storing the donations at room temperature, as opposed to the existing method of refrigerating these tissues.

The MOPS was found to preserve samples for as much as 60 days, compared to the 28 days achieve with the present technique.

Study co-author James Cook said: "Time is a serious factor when it comes to utilising donated tissue for joint repairs.”
He added that most of the existing 28-day window is currently needed to test whether the tissue is safe for transplant, decreasing the chance of finding a suitable recipient in time.
