In Short
Day-case knee replacement allows carefully selected patients to have knee replacement surgery and go home the same day. It relies on an enhanced recovery protocol built around spinal anaesthesia with sedation, local anaesthetic infiltration, and early mobilisation, with the same implants and the same surgical standards as an inpatient operation for advanced knee arthritis. Mr Shakir Hussain assesses day-case suitability at consultation.
A Modern Approach
What Is Day-Case Knee Replacement?
Day-case knee replacement is a total or partial knee replacement in which the patient is admitted on the morning of surgery, undergoes the procedure, completes the initial physiotherapy milestones, and returns home the same evening. It is also described as same-day knee replacement or outpatient knee arthroplasty.
Day-case knee replacement is not suitable for everyone. But for patients who meet the criteria, it offers the comfort of recovering at home from the first night, which many patients prefer, with no compromise on safety or outcome compared to an inpatient stay.
Who is suitable for day-case knee replacement?
Suitability criteria typically include:
- ASA grade 1 or 2 (fit, or well-controlled minor systemic disease)
- BMI under 35 to 40
- No significant cardiovascular, respiratory, or renal comorbidities
- Uncomplicated primary knee replacement (total or partial)
- Adequate home support: a responsible adult at home for at least 24 hours
- Motivated patient who understands the day-case pathway
- Home within 60 minutes of the hospital
What makes it safe to go home the same day?
Day-case knee replacement is safe because it relies on an enhanced recovery protocol rather than reduced care. Key elements include:
- Spinal anaesthesia with light sedation, avoiding the lingering effects of general anaesthesia
- Periarticular local anaesthetic infiltration during surgery for immediate post-operative pain control
- Oral multimodal analgesia protocol prescribed before discharge
- Physiotherapy on the same day: patients must walk 50 metres before going home
- Nurse phone review on day 1 and clear escalation pathway if problems arise
What to Expect
The Day-Case Knee Replacement Experience
Understanding what happens on the day helps patients feel prepared and confident.
Morning of Surgery
Arrive at hospital 2 hours before your scheduled operating time. Pre-operative nurse assessment, anaesthetic review, and consent confirmation. Pre-emptive analgesia given.
The Operation
Knee replacement is performed under spinal anaesthesia. Total operating time is typically 60 to 90 minutes. Periarticular local anaesthetic is infiltrated into the knee before wound closure.
Recovery and Physiotherapy
You will wake in the recovery room. Once comfortable and stable, a physiotherapist will help you stand and walk. Discharge criteria include walking 50 metres unaided, controlled pain, and ability to manage stairs.
Going Home
Most day-case patients go home in the early evening. A responsible adult must accompany you and stay overnight. You will have a full analgesia prescription and written instructions for the first week.
Day 1 Follow-Up
A nurse will call you the morning after surgery to check on pain, wound, swelling, and how you are mobilising. You can call the ward at any time if you have concerns.
Ongoing Recovery
Recovery after day-case knee replacement follows the same milestones as inpatient surgery: walking aid for 2 to 4 weeks, driving at 6 weeks, most activities by 3 months.
