What should you know about Zimmer total knee replacement?

In a total knee replacement, the surgeon resurfaces the ends of the thighbone and shinbone and may replace the underside of the kneecap. A metal alloy component meets a durable plastic bearing, and bone cement or a press-fit design may secure parts. Titanium may be used in some implant components. Zimmer is the manufacturer; the exact design and materials depend on your anatomy and surgeon’s plan.

Knee osteoarthritis is one reason people consider this operation when pain, stiffness, or difficulty climbing stairs continues to limit everyday life. The operation replaces joint surfaces, not every structure around the knee.

Before surgery, review medicines, medical conditions, dental issues, and skin health with your team. Prepare a chair, raised toilet support if advised, and a safe walking route. Rehabilitation usually starts with ankle movement, breathing exercises, knee bending and straightening, and assisted walking. Regular practice helps restore strength and confidence; progress is guided by swelling, wound healing, knee motion, and balance.

Use your prescribed pain plan and attend reviews. Ask when kneeling, driving, work, and higher-impact activities are appropriate for your implant and recovery.

Contact the surgical team for fever, increasing wound redness, drainage, worsening pain, or a calf that becomes newly swollen and painful. Emergency symptoms include sudden chest pain, difficult breathing, fainting, or a foot that becomes cold or changes colour. A sudden loss of movement or inability to bear the permitted weight also warrants prompt assessment.
