Introduction
Knee pain can make everyday activities such as walking, climbing stairs, or getting up from a chair increasingly difficult, particularly when arthritis or significant joint damage is involved. When medicines, physiotherapy, injections, and lifestyle changes no longer provide sufficient relief, knee replacement surgery may be considered to reduce pain and improve mobility. Understanding who may need surgery, how the knee replacement procedure is performed, the different types available, and what recovery involves can help patients prepare for an informed discussion with their orthopaedic specialist.
What Is Knee Replacement Surgery?
Knee replacement surgery is a procedure that replaces damaged cartilage and bone in the knee joint with artificial implants made from metal, ceramic, or durable plastic. The goal is to reduce pain, improve movement, and restore everyday function.
Some of the common reasons doctors may recommend knee replacement surgery include:-
- Osteoarthritis, which can cause gradual wear and tear of the knee joint
- Rheumatoid arthritis that leads to inflammation and joint damage
- Arthritis caused by a previous knee injury
- Severe injuries that affect knee movement and stability
- Changes in knee shape or alignment due to joint damage
Action: If knee pain is making it difficult to walk, climb stairs, or manage daily activities, it is a good time to speak with an orthopaedic specialist for proper evaluation.
Info Gain: More than 90% of modern knee replacements continue to function well for 15â20 years when combined with proper rehabilitation and healthy lifestyle habits.
