If you’ve been told you might need a knee replacement, you probably have plenty of questions. Here’s an honest, plain-language overview to help you decide whether it’s the right step for you.
What Is a Knee Replacement?
Knee replacement (also called knee arthroplasty) is a surgery where damaged parts of the knee joint are replaced with smooth metal and plastic implants. It’s typically recommended when severe arthritis or injury has worn down the joint, causing pain that no longer responds to medication or physiotherapy.
Who Is a Candidate?
You may be a candidate if you have severe knee pain that limits daily activities, stiffness that doesn’t improve with treatment, X-ray evidence of significant joint damage, and have tried conservative options without lasting relief.
What Happens During Surgery?
The procedure typically takes 1–2 hours under spinal or general anesthesia. The surgeon removes damaged cartilage and bone, then fits the new implant. Most patients stay in the hospital for 2–4 days.
Recovery Timeline
- Week 1–2: Walking with support, basic exercises, pain management
- Week 3–6: Gradual return to daily activities, structured physiotherapy
- Month 3: Most daily activities resumed, walking comfortably
- Month 6–12: Full recovery; many patients return to low-impact sports
What Are the Risks?
Knee replacement is generally safe, but like any surgery, it carries risks including infection, blood clots, and implant wear. Your surgeon will discuss these in detail and explain how they’re minimized.
How Long Do Implants Last?
Modern knee implants typically last 15–20 years or more, depending on activity level and individual factors.
