Knee replacements: Why are they required?

Top Doctors speaks to leading consultant trauma and orthopaedic knee surgeon Mr Saket Tibrewal about when knee replacements become necessary, and all about what’s involved in the process in this informative article.

Why would someone require a knee replacement?

A knee replacement usually becomes necessary when the knee joint becomes arthritic. Persistent pain, stiffness, difficulty walking, and limited daily activities may indicate the need for this surgical intervention if other measures to control the symptoms fail.

What's the best age to have a knee replacement?

There is no specific age requirement for knee replacement, although there are less predictable outcomes in patients under 60 years old.  The final decision depends on individual health and circumstances.

Generally, this surgery is considered when knee pain and impaired function significantly impact your quality of life. Your orthopaedic surgeon will assess your condition and guide you on the most suitable timing.

Are knee replacements painful?

Yes, there is pain following knee surgery, however post-operative pain is managed carefully with medications and other pain relief strategies.

Advancements in pain management techniques have significantly minimised post-surgery pain. The first few weeks can be difficult; however, most patients experience improved comfort as they progress through rehabilitation.

What are the advantages and disadvantages of a knee replacement?

Advantages include:

• reduced pain;
• improved mobility, and;
• ultimately an enhanced quality of life.

However, like any surgery, knee replacement has potential risks, such as:

• infection;
• blood clots;
• persistent pain;
• stiffness or swelling.

Your healthcare team will discuss the specific benefits and risks based on your individual health.

How long does it take to recover from a replacement knee?

Recovery duration varies. Patients can walk immediately and generally only need to spend a couple of days in hospital, although in some cases it may be possible to do the surgery as a day case.  Patients typically resume light activities within a few weeks and can drive after six weeks.

Full recovery

Full recovery may take several months and requires physical therapy to regain strength and mobility. It’s crucial to follow your surgeon's guidance, attend rehabilitation sessions, and engage in prescribed exercises for optimal recovery.
