Step 1 - Your pre-operative assessment

ℹ️ This appointment takes place 2-4 weeks before surgery. Blood tests, MRSA screening, medication review, and anaesthetic assessment are performed.

Total hip replacement is performed under general or spinal anaesthetic and takes approximately 60-90 minutes. Hospital stay is typically 2-3 nights with modern enhanced recovery programmes.

What will happen at the pre-assessment?

Blood tests, ECG, and chest X-ray

Routine investigations to confirm fitness for anaesthetic.

MRSA screening

Nasal and groin swabs. Decolonisation treatment if positive.

Medication review

Blood thinners and NSAIDs paused. Blood pressure medications usually continued.

Home preparation

Raise toilet seat, install shower grab rail, arrange ground floor living for first 2 weeks if possible. Clear floor hazards to prevent falls.

Dental treatment before surgery

Any planned dental treatment should be completed before your hip replacement. Dental bacteria entering the bloodstream can seed a hip prosthesis - particularly in the first 2 years after surgery.

The day of surgery

ℹ️ You will be given a specific arrival time. Do not eat or drink (other than clear water up to 2 hours before) from midnight the night before. Bring your medication list and any documents sent by the hospital.

Arrive at the time given

You will be admitted to the ward or day surgery unit, change into a gown, and be seen by the nursing, anaesthetic, and surgical teams before theatre.

Consent and marking

Your surgeon will confirm the procedure, mark the operative side, and you will sign a consent form before going to theatre.

Anaesthetic

You will meet the anaesthetist in the anaesthetic room. Once anaesthesia is established, the procedure will begin.

Recovery room

After surgery you will wake in the recovery room where nurses monitor your vital signs until you are stable and comfortable.

In hospital

Most patients having arthroscopic or day-case procedures go home on the day of surgery. Those having joint replacement typically stay 1–2 nights. Before discharge, the team will check your pain is controlled, give you wound care instructions, and confirm your follow-up appointment.

Pain control

You will be given oral pain relief before discharge. Take it regularly for the first 48 hours rather than waiting until pain is severe.

Wound check and dressing

A nurse will check the wound before you leave and explain how to keep it clean and dry.

Discharge letter and follow-up

You will receive a letter for your GP and details of your next outpatient appointment - usually at 2 weeks for a wound check.

You must not drive yourself home

Arrange for a family member or friend to collect you. You must not drive on the day of surgery if you have had a general anaesthetic or sedation.

Going home

⚠️ Important: Seek urgent assessment if you develop severe hip pain with or without a clunk - this may indicate dislocation. Also seek urgent assessment for wound infection signs: redness, heat, discharge, or fever.

Keep the wound clean and dry

Avoid getting the wound wet until it is fully healed - usually 10–14 days. Use a waterproof cover or cling film when showering.

Take your pain relief as prescribed

Do not wait until pain is severe before taking medication. Regular simple analgesia (paracetamol, ibuprofen if appropriate) is more effective.

Attend your wound check appointment

This is usually 2 weeks after surgery. Sutures or clips will be removed if used.

When to contact the hospital

Seek urgent advice if you develop increasing redness, warmth, swelling, discharge from the wound, or a temperature above 38°C - these may indicate infection.

Recovery week by week

2-4 weeks before

Pre-operative assessment

Blood tests, MRSA screen, anaesthetic discussion, home preparation.

Day of surgery

Arrive, anaesthetic, procedure

60-90 minutes in theatre. Hospital stay 2-3 nights.

Day 1

Walking with a frame

A physiotherapist will help you stand and walk the day after surgery.

Weeks 2-6

Building independence

Progress from frame to crutches to stick. Observe hip precautions throughout.

Weeks 6-12

Return to driving and normal activity

Driving at 6-8 weeks. Low-impact sport from 3 months.

Common questions

What are hip precautions and how long do I need them?

Hip precautions are movement restrictions to prevent dislocation. The specific restrictions depend on the surgical approach. Most surgeons advise avoiding crossing the legs and bending the hip beyond 90 degrees for 6-12 weeks. Your surgical team will give you specific instructions.

When can I drive?

Most patients return to driving at 6-10 weeks, when they can safely perform an emergency stop. Right hip replacement patients need a longer period off driving. Confirm with your insurer.

Can I fly after hip replacement?

Flying is generally not recommended for the first 6-12 weeks due to DVT risk. After this, you can fly with compression stockings and regular movement during the flight.
