Yale Medicine orthopaedic surgeon Dr. Daniel Wiznia explains how this joint-preserving procedure works, how successful it is, and what recovery is really like.

In today’s health headlines: why osteoarthritis is so painful, what to know about a new injection treatment, and how it differs from other treatments that are currently available. Dr. Chuan-Ju Liu, professor and vice chair of research in the Department of Orthopaedics and Rehabilitation at Yale School of Medicine, joined Good Morning Connecticut at 9 a.m. to tell us more.

Osteoarthritis is a chronic disease of the entire joint and is often assumed to be an inevitable part of aging. But researchers are working to better understand the condition in a much more nuanced way. In this Q&A, Chuan-Ju Liu, PhD, Charles W. Ohse Professor of Orthopaedics & Rehabilitation and vice chair of research with the Department of Orthopaedics & Rehabilitation at Yale School of Medicine, shares more about osteoarthritis, the groundbreaking research taking place at Yale, and what future treatments may look like.

"The technical agreement we saw between the foot-mounted sensors and the laboratory motion capture system was exceptionally strong," said lead researcher Dr. Charles Odonkor, an associate professor of orthopedics and rehabilitation at Yale School of Medicine in New Haven, Connecticut.

It’s also “better at improving cardiovascular endurance, as it is a higher intensity and strain on the body,” Elizabeth Gardner, MD, an associate professor of orthopedic surgery at Yale School of Medicine, told Health.

Knee osteoarthritis is a widespread and painful joint condition. It causes chronic pain, cartilage breakdown, and trouble moving. Doctors rely on X-rays and patient surveys to track how the disease progresses. These traditional methods have a major blind spot. They do not show how a person actually moves during daily life outside of a clinical exam. Researchers are turning to wearable technology to bridge this gap, such as small sensors that can record highly precise motion data.

But if tea isn’t for you, or you prefer to drink coffee, you don’t have to force yourself to change your beverage of choice. “What the study shows is that there’s a very small positive association between tea drinking and bone density. But while statistically significant, it’s not necessarily a clinically meaningful improvement,” explains Daniel Wiznia, M.D., an associate professor of orthopaedics at Yale School of Medicine and co-director of Yale’s avascular necrosis & osteonecrosis program.

As more individuals with cerebral palsy live well into adulthood, medical professionals are taking a closer look at the unique long-term healthcare needs of this patient population. While adults with cerebral palsy require the same routine health maintenance as anyone else, a large, national study conducted at Yale showed that women living with cerebral palsy received significantly less preventative gynecologic care than women without the condition.
