A clear guide for patients at Joint Care, Patiala, explaining the knee replacement procedure, preparation, recovery and after‑care tips.
Why Knee Replacement May Be Recommended
When the knee joint is damaged by osteoarthritis, rheumatoid arthritis or injury, pain and stiffness can limit daily activities. Knee replacement surgery (total knee arthroplasty) replaces the worn surfaces with prosthetic components, helping to restore function and relieve pain.
How the Procedure Is Performed
Step‑by‑step overview
- Pre‑operative assessment: Blood tests, X‑ray or MRI, and a discussion of medical history.
- Anaesthesia: Most patients receive spinal or epidural anaesthesia; general anaesthesia is also an option.
- Surgical steps: The surgeon makes a small incision, removes damaged cartilage and bone, and fits the prosthetic components.
- Closure: The incision is closed with sutures or skin glue, and a sterile dressing is applied.
Preparing for Surgery
- Arrange a trusted family member or friend to accompany you on the day of surgery.
- Follow the prescribed fasting instructions (usually no solid food after midnight).
- Stop smoking at least two weeks before the operation to improve healing.
- Discuss any current medications with your orthopaedic surgeon, especially blood thinners.
Recovery and Rehabilitation
Hospital stay
Most patients stay 2–4 days in the hospital. Pain is managed with medication, and gentle physiotherapy begins on the first day.
Home care
- Keep the incision clean and dry; follow dressing change instructions.
- Perform the prescribed exercises several times a day to improve range of motion.
- Use walking aids (crutches or a walker) as advised, and avoid putting full weight on the operated leg for the first few weeks.
- Attend scheduled physiotherapy sessions for at least 6–8 weeks.

If you notice increasing pain, swelling, redness, fever, or drainage from the incision, contact Joint Care immediately.
