Bio-Degradable Scaffold To Fix Damaged Knees Developed by Indian-Origin Researcher and Team

Patients with damaged knee cartilage can hope to be treated with a biodegradable scaffold developed by a research team at Hospital for Special Surgery, including an Indian-origin scientist.

Dr Asheesh Bedi, a fellow in sports medicine and shoulder surgery at Hospital for Special Surgery, has revealed that his team's invention is a Trufit plug that has mechanical properties similar to cartilage and bone.

Patella fracture is a kneecap injury that needs surgical correction. Undisplaced fracture can be healed by using a brace to keep the knee immobile.

"The data has been encouraging to support further evaluation of this synthetic scaffold as a cartilage repair technique," he said.

Damage to so-called articular cartilage can occur in various ways, ranging from direct trauma in a motor vehicle accident to a noncontact, pivoting event on the soccer field.

The Trufit plug has two layers. The top layer has properties similar to cartilage and the lower layer has properties similar to bone.

The bilayered structure has mechanical properties that approximately match the adjacent cartilage and bone.

During the study, surgeons inserted the plug in the knees of 26 patients with donor lesions from OATS procedures and followed up with imaging studies (with MRI and T2-mapping) at various intervals for a period of 39 months.

Osteoarthritis - Causes, Symptoms, DIagnosis, Treatment, FAQs
Osteoarthritis is one of the commonest joint disorder and occurs as we age due to wear and tear of a joint. Osteoarthritis can affect any joint of the body.

"Quantitative MRI, when combined with morphologic assessment, allows us to understand the natural history of these repair techniques and define those patients who are most likely to benefit from the surgery," said Hollis Potter, M.D., chief of the Division of Magnetic Resonance Imaging, director of Research in the Department of Radiology and Imaging at Hospital for Special Surgery and lead author of the study.

"We gain knowledge about the biology of integration with the host tissue, as well as the repair tissue biochemistry, all by a noninvasive imaging technique," he added.

Increase in the Demand for Artificial Joints
According to the study conducted by Steven M. Kurtz there is an increase in demand for artificial hips.

"What we found was that the plug demonstrated a predictable process of maturation on imaging studies that paralleled the biology of their incorporation," Bedi said.

The findings were presented at annual meeting of the American Orthopedic Society for Sports Medicine.
