Researchers watch the knee degenerate and understand how osteoarthritis may begin

For hockey great Bobby Orr, a torn knee ligament ended his career at age 30. Orr had more than 17 knee operations, at one point having his meniscus removed—the cartilaginous tissue that helps stabilize and lubricate the knee joint. Now scientists can see in real time just how important the meniscus is.
"Four decades ago, it was accepted that the meniscus didn't play a significant role in the knee joint. When someone damaged their meniscus, surgeons usually removed all or part of it—as they did with Bobby Orr," says Dr. Ziad Abusara, Ph.D., Faculty of Kinesiology, who won an award from the Orthopaedic Research Society in 2017 for his study findings.
"Only later, it was discovered that most patients who had their meniscus removed developed knee osteoarthritis."
