What Happens at Your Preoperative Assessment
Once surgery has been agreed as the right next step, you'll be booked in for a preoperative assessment. Here's what this appointment actually involves, and why it matters.

What Is a Preoperative Assessment?
A preoperative assessment is a dedicated appointment, usually with a nurse or specialist team, to check you're fit and well-prepared for surgery and anaesthesia. It's designed to identify anything that needs addressing beforehand, reducing the risk of complications and cancellations on the day of surgery.
Health Questionnaire and History
You'll be asked detailed questions about your general health, any existing medical conditions, previous surgeries or anaesthetics, allergies, and current medications, including over-the-counter and herbal supplements. Being thorough and honest here directly supports your safety.
Physical Checks
Common checks include blood pressure, heart rate, weight and height, and listening to your heart and lungs. Depending on your health history and the specific surgery planned, additional checks may be arranged.
Blood Tests and Investigations
Blood tests are routine, checking things like blood count and clotting function. Depending on your age and health background, you may also have an ECG (heart trace) or other investigations arranged, such as MRSA screening swabs, which are standard practice before joint replacement surgery.
Discussing Anaesthesia
You'll typically have the opportunity to discuss anaesthesia options relevant to your procedure — general or spinal anaesthesia for hip and knee surgery, for example — with the anaesthetic team, including any specific concerns or previous experiences you want to raise.
Medication Planning
Some medications — particularly blood thinners — may need to be paused or adjusted before surgery, under medical guidance. This appointment is where that plan gets confirmed, so there's no ambiguity about what to take and what to stop, and when.
Practical Planning for the Day
You'll usually receive clear instructions on fasting before surgery, what to bring into hospital, and what to expect on the day itself. This is also a good opportunity to ask any remaining questions about the procedure, hospital stay, or recovery.
Why This Step Matters
A thorough preoperative assessment reduces the risk of last-minute surgery cancellations and helps the surgical and anaesthetic teams plan safely around your individual health profile. It's a routine part of preparing well for hip or knee surgery, not an extra hurdle — and it exists to support a smoother, safer outcome.
