Rebuilding a Worn Out Joint by Injection

When arthritis attacks the cartilage layer that allows bone joints to slide smoothly, the bones begin grinding and cause damage and discomfort. We know how to fix this problem with artificial replacements, but that requires surgery which can be invasive, is expensive and takes time and therapy for full recovery.

Professor Karperien in the Netherlands suggests a technique for injecting a plaster that creates a scaffold for self repair.

Injectable plasters: the future for osteoarthritis patients – []

You inject a ‘liquid plaster’ into the worn-out knee of an osteoarthritis patient. The plaster hardens in the joint and attaches to the damaged cartilage, then induces the body to repair the damage. A few weeks later the patient can walk pain-free and problem-free again. This is the ideal Professor Marcel Karperien of the University of Twente’s MIRA research institute sees before him – but an ideal that he believes could be put into practice within a few years.
