Scientist have developed a 3D-printed knee to help patients suffering from osteoarthritis

Scientists at the University of Bath have developed a 3D-printed implant to help patients suffering from osteoarthritis in their knee. The tailored osteotomy for knee alignment treatment aims to preserve the patient's existing knee joint.

The technique makes knee operations quicker and safer. The 3D-printed high-tibial osteotomy (HTO) plates realign the knee, improving stability, comfort, and weight-bearing ability.

David Tarbet, one of the first patients to receive the treatment, described the surgery as "remarkable." After a couple of months of recovery, he was able to ride an indoor bike and complete a competitive bike ride within six months.

Doctors use X-rays and CT scans to plan the correction needed for each patient. A surgical guide stabilisation plate is generated using a 3D printer and temporarily fitted to the patient's tibia.

The HTO plates underwent a virtual computer-based trial using CT scan data from 28 patients, demonstrating their safety.

Further trials are being conducted to compare the technique with traditional knee replacement surgeries.

The goal is to make the joint-preserving surgery more widely available and accessible to patients.
