This is a question many patients want to ask but feel awkward raising. It deserves a clear and respectful answer. Weight does play a part in hip and knee replacement, but it is rarely a simple yes or no. Being above an ideal weight does not automatically rule out surgery. Mr Kosuge believes patients should understand the facts so they can make informed decisions, without judgement.
Why weight matters at all
Carrying extra weight increases the load through the hip and knee joints, which is part of why heavier patients often develop symptoms of arthritis. Around the operation itself, a higher body weight can increase certain risks, including wound healing problems, infection, blood clots and the demands of the anaesthetic. These are the reasons weight is discussed. They are practical rather than personal.
How surgeons actually use weight in the decision
Many units refer to body mass index, or BMI, as one factor in planning surgery. It is important to understand that a BMI figure is a guide, not a rigid cut-off applied on its own. The decision considers the whole picture, including your general health, your symptoms, how much the arthritis is affecting your life and the balance of risks and benefits for you as an individual. For many patients above an ideal weight, replacement surgery is still entirely appropriate and highly successful.
What losing some weight before surgery can do
Where there is time, losing even a modest amount of weight before surgery can reduce the risks above and can ease the load on the joint afterwards. It is one of the most useful things a patient can do to help their own outcome, alongside staying active within the limits of the pain. This is not about reaching an ideal figure. It is about improving the odds in your favour.
A supportive conversation, not a barrier
The purpose of discussing weight is never to turn patients away. It is to make surgery as safe as possible and to give the best chance of a good result. Where weight is a genuine concern, Mr Kosuge will discuss it honestly and set out a sensible plan, which may include support to lose some weight before proceeding.
