Knee pain can gradually change the way we walk, work, exercise, and enjoy everyday life. While many knee conditions can be managed with medicines, physiotherapy, activity modification, or injections, some patients eventually develop advanced arthritis where these measures no longer provide sufficient relief.
For carefully selected patients, Total Knee Replacement (TKR) can be an option to replace damaged joint surfaces and help restore knee function. Knee replacement is commonly performed for advanced osteoarthritis and is generally considered after appropriate non-surgical treatments have not provided adequate relief.
What Is Total Knee Replacement?
The knee is formed by the lower end of the thigh bone (femur), the upper end of the shin bone (tibia), and the kneecap (patella). Healthy cartilage allows these surfaces to move smoothly.
With advanced arthritis, the protective cartilage can become severely damaged. This may result in:
- Persistent knee pain
- Stiffness
- Swelling
- Difficulty walking or climbing stairs
- Reduced ability to perform daily activities
- Pain during prolonged standing or activity
During total knee replacement, the damaged joint surfaces are removed and replaced with prosthetic components designed to allow smoother movement of the knee.
When Should You Consider Knee Replacement?
A knee replacement is not automatically required simply because an X-ray shows arthritis.
The decision should consider your symptoms, examination findings, imaging, activity limitations, overall health, and response to non-surgical treatment.
Knee replacement may be discussed when:
1. Pain is persistent
Pain continues despite appropriate conservative treatment.
2. Daily activities become difficult
Walking, climbing stairs, standing, or performing routine activities becomes increasingly difficult.
3. Arthritis is advanced
Imaging and clinical examination demonstrate significant joint degeneration.
4. Non-surgical treatment is no longer providing adequate relief
Treatment such as physiotherapy, medicines, activity modification, or appropriately selected injections has not provided sufficient improvement.
The decision should always be individualised after a proper orthopaedic assessment.
Total vs Partial Knee Replacement
Not every arthritic knee requires replacement of the entire joint.
In selected patients where arthritis is limited to a specific compartment, partial knee replacement may be considered. Total knee replacement addresses the affected joint surfaces more extensively.
Whether total or partial replacement is appropriate depends on the location and extent of arthritis, ligament function, alignment, activity requirements, and other clinical factors.
What Happens Before Surgery?
A successful knee replacement journey begins well before entering the operating theatre.
1. Detailed Clinical Assessment
I evaluate your symptoms, walking pattern, knee movement, alignment, stability, and functional limitations.
2. Imaging
Appropriate imaging—commonly X-rays and, when indicated, additional imaging—helps assess the extent and pattern of joint damage.
3. Treatment Discussion
We discuss both surgical and non-surgical options, expected outcomes, potential risks, and the rehabilitation process.
4. Medical Preparation
Your general health and any conditions that could affect surgery or recovery are reviewed and optimised where appropriate.
What Happens During Knee Replacement?
During surgery, the damaged portions of the knee are prepared and replaced with prosthetic components. The objective is to restore appropriate alignment and provide a stable, functional knee.
Modern knee replacement surgery combines careful surgical planning, appropriate implant selection, accurate bone preparation, and attention to soft-tissue balance.
The exact surgical technique and implant choice depend on the individual patient’s anatomy and clinical requirements.
Recovery After Knee Replacement
Surgery is only one part of the treatment journey.
Rehabilitation plays an important role in recovery.
Following surgery, the rehabilitation programme generally focuses on:
- Controlling pain and swelling
- Restoring knee movement
- Strengthening the muscles around the knee
- Improving walking and mobility
- Gradually returning to everyday activities
- Building confidence in the operated leg
Recovery varies from patient to patient. Age, overall health, muscle strength, pre-operative mobility, surgical factors, and adherence to rehabilitation can all influence the recovery process.
What Can Patients Expect From Knee Replacement?
The primary objectives of knee replacement are to reduce pain and improve function.
Patients may experience improved ability to walk and perform everyday activities after appropriate recovery and rehabilitation. However, knee replacement is a major surgical procedure, and individual outcomes can vary.
It is important to have realistic expectations and understand that recovery takes time.
Is Knee Replacement Right for You?
There is no single age or fixed rule that determines whether someone should undergo knee replacement.
The more important questions are:
- How severe are your symptoms?
- How much do they affect your daily life?
- What does your examination show?
- How advanced is the joint damage?
- Have appropriate non-surgical treatments been tried?
- What are your individual health and activity goals?
A detailed consultation can help answer these questions.
A Personalised Approach to Joint Replacement
My approach is to first understand the patient’s problem rather than simply treat an X-ray.
For every patient, the aim is to determine the underlying cause of pain, understand functional limitations, discuss available treatment options, and develop an appropriate plan based on the individual’s condition and goals.
If knee arthritis is affecting your mobility or quality of life, an orthopaedic evaluation can help determine whether continued conservative treatment, joint-preservation treatment, partial replacement, or total knee replacement is appropriate.
