Athletes crippled by debilitating knee injuries could be hopping back to recovery through kangaroo tendon transplants.

Kangaroo tendons could replace damaged knee ligaments in humans. Scientists at Macquarie University have been researching how these tendons could be used to treat a ruptured anterior cruciate ligament, a serious and painful sporting injury.

An ACL rupture can mean the end of a season or even a career, as it requires reconstructive surgery and months of rehabilitation. In Australia, 90 per cent of ACL replacements are completed using a tendon taken from elsewhere in the body, with the rest using donations made by people after their death.

But tendons from a dead kangaroo were found to be six times stronger than human tendons. So far the research shows promise that the kangaroo tendons will not be rejected and could be stronger and more durable than other graft options.
