Inventors at Aberdeen University have come up with a new medical screw implant which they believe could "revolutionise" major knee surgery.
The mechanism, which has been developed in partnership with the Royal Orthopaedic Hospital in Birmingham, has been designed to help treat people suffering from damage to the cruciate knee ligaments.
Injuries to this part of the knee, which is known as the anterior cruciate ligament (ACL), are particularly common in sportspeople.
The GraftBolt, as the device is called, is allegedly stronger than existing ones and improves the quality of bonding between bones and tendons.
Team leader Dr Bin Wang said: "GraftBolt aims to improve the patient’s quality of life by successfully repairing their injury first time and improving the quality of bonding of the graft to the bone, which speeds up the healing of the graft implant and hence improves the patient’s rehabilitation."
Current ACL surgery involves using the patient's hamstring tendons to form a graft.
ACL surgery is common among people who play sport professionally.
Recently, ballet dancer Pamela Swaney has returned to the stage after undergoing treatment last year.
