Knee pain affects about a fifth of over-16s, and is more common the older we get.
Per the NHS, it can be caused by everything from strains and twists during exercise to conditions like osteoarthritis (knee osteoarthritis seems to be the most common form of the disease).
According to Dr Syed Nadeem Abbas, a surgeon and regenerative medicine expert from the Knee Pain Clinic, “most knee pain [among over-40s] comes down to wear and tear, and that’s still the most likely explanation.”
However, he says one type of knee pain should always be investigated.

“What tends to get missed is pain that doesn’t follow the usual rules, pain that’s worse at rest than at activity, or wakes someone up at night rather than settling,” the expert said.
