A cartilage repair gel that could delay the need for invasive surgery for five years or more, is being developed by The University of Bradford, and university spin out company Advanced Gel Technology.

The hydrogel, which is not yet ready for clinical trials, is intended for use with traumatic injuries, including those sustained in car collisions or sports.

Lead researcher of the Cartilage Repair Project at The University of Bradford, Pete Twigg, explained: “Total joint replacement is very successful, but may not be appropriate for younger, more active people. They are often encouraged to put off surgery until the pain is disabling, but a conservative replacement treatment could relieve the pain and restore function at a much earlier stage.”

The technique involves drilling a hole into the affected area and filling it with the gel. This gel takes the place of missing or damaged cartilage, preventing bones from grinding against each other.”

The researchers are hoping to simplify the project to the point where it can be conducted as a day surgery.
