Is it true that knee replacements only last ten years and leave you unable to walk properly?

Myth: a new knee only lasts ten years

Large joint registries show that most knee replacements are still working at 15 to 20 years, and many last longer. Implant life depends on your age and activity level, body weight, and how well the components were positioned. Younger, very active patients do have a higher chance of needing a revision during their lifetime, which is why timing is discussed carefully.

Myth: I am too old for surgery

Chronological age matters less than general health. Fit patients in their eighties can have a replacement safely and benefit greatly. What matters is heart and lung health, diabetes control, kidney function and the ability to take part in rehabilitation. A pre-operative assessment identifies risks and how to reduce them.

Myth: you will be bedridden for weeks

Most patients stand and walk with a frame or crutches on the day of surgery or the next day. Hospital stays are usually short, and most people are walking independently within a few weeks. The full benefit takes months, but early movement is a central part of modern recovery.

More beliefs worth correcting

• You do not have to wait until the pain is unbearable; persistent limitation despite good non-surgical care is enough to discuss it
• A replacement does not set off airport scanners in a way that stops you travelling; you simply mention it at security
• Kneeling is usually possible, though often uncomfortable on a hard floor
• The whole knee is not removed; only the worn surfaces are resurfaced
• Physiotherapy is not optional; it shapes the result as much as the operation
