A health expert has warned that delaying knee replacement surgery can reduce a patient's ability to function after surgery.
According to physiotherapist Dr Lynn Snyder-Mackler, doctors have historically advised patients to delay having a knee replacement until they cannot bear the pain any longer.
She told KDKA.com: "What's driven the timing, really, of total knee… is the physician's concerns that the knees won't last long enough."
However, modern implants last longer and patients should now not be afraid of undergoing knee replacement surgery sooner rather than later.
In fact, the expert suggested that it may be detrimental to delay surgery, explaining that "pretty much how you start is how you finish".
"So if your function is poorer before surgery, it's going to be poorer after surgery."
Patients who do not want to wait for a knee replacement operation on the NHS may consider seeking private treatment.
A private knee replacement usually costs in the region of £8,000 to £10,000 in a UK hospital.
What's better? Private or NHS healthcare?
