Total Knee Replacement: When to Consider It & Recovery Timeline

Severe osteoarthritis of the knee can severely restrict walking, climbing stairs, and enjoying daily life. When physiotherapy, weight management, and knee injections no longer provide relief, Total Knee Replacement (TKR) is a highly reliable surgical option. ### What Happens During a Knee Replacement? The surgeon does not replace the entire knee joint; rather, the worn-out cartilage surfaces at the end of the thigh bone (femur) and top of the shin bone (tibia) are resurfaced with precision metal components. A durable medical-grade polyethylene spacer is placed between them to restore smooth, frictionless gliding. ### The Fast-Track Recovery Milestone - **Day 1**: Standing and taking assisted steps with a walker under physiotherapist supervision. - **Day 3–4**: Comfortable stair climbing practice and discharge home. - **Weeks 2–3**: Sutures/staples removed; transitioning from a walker to a simple stick. - **Weeks 6+**: Independent walking, driving, and returning to everyday routine activities without persistent pain.
