Every patient’s recovery is unique, and guidance may vary depending on your surgeon’s recommendations and individual circumstances.

Immediately After Surgery
You will usually wake up in the recovery area where nurses monitor your vital signs and comfort. Pain relief will be provided, often through medication or local anaesthetic techniques. Most patients are encouraged to begin moving the knee within 24 hours.
Hospital Stay
The average hospital stay is between 2–5 days, depending on your recovery and mobility. Physiotherapists will work with you to help you walk with support, practice stairs, and improve knee function. You may go home when you can safely walk with aids and manage basic activities.
Pain and Swelling
It is normal to experience pain, swelling, and stiffness after surgery. Pain medication, ice packs, and elevation can help. Swelling may last for weeks or months, and regular exercises are important for improvement.
Rehabilitation and Exercises
Exercise is a vital part of recovery. You will be given a physiotherapy program to follow, focusing on strengthening muscles and improving range of motion. Walking, gentle stretching, and strengthening exercises help restore mobility.
Returning Home
You may need support with daily activities initially. Remove trip hazards and consider safety aids at home. Walking aids such as crutches or a frame are usually needed for several weeks.
Recovery Timeline
- First 6 weeks: Focus on pain control, mobility with aids, and physiotherapy.
- 6–12 weeks: Gradual improvement in strength and independence.
- 3–6 months: Most patients notice significant improvement in function and reduced
pain. - 12 months: Full recovery and final results are usually achieved.
Activities and Lifestyle
Low-impact activities such as walking, swimming, cycling, and golf are encouraged after recovery. High-impact activities like running and jumping should generally be avoided to prolong implant life.
When to Seek Help
Contact your healthcare team urgently if you experience:
- Sudden severe pain
- Signs of infection (redness, swelling, fever, wound discharge)
- Difficulty moving your leg
- Chest pain or shortness of breath
Every patient’s recovery journey is unique. Following your surgeon’s and physiotherapist’s advice, staying active, and practicing patience are key to a successful outcome.
