Joint Replacement: A Primer
ACCORDING TO THE CANADIAN JOINT REPLACEMENT REGISTRY more than 40,000 total hip and knee joint replacements are performed in Canada each year and an estimated 35 per cent were performed on patients under 65. Dr. John McCall, an orthopedic surgeon based in Collingwood, Ont., who performed one of the first hip replacement operations in Canada in the ’70s, says the basic principal of joint replacement hasn’t changed significantly since the procedure was pioneered by Sir John Charnley in England in the 1960s.
“It’s still a gold standard,” says McCall, who attended Charnley’s lectures when he was a young doctor. Recent advancements include:
Advanced engineering of the replacement joint, which ensures a better fit, often eliminating the need for “cement,” which results in better function.
