For patients whose daily activities or sleep are affected by chronic knee pain, private surgery at Chelsfield Park offers fast access, consultant-led care, and a smoother recovery experience.

What is total knee replacement surgery?
A total knee replacement involves removing the damaged surfaces of the thigh bone (femur), shin bone (tibia), and sometimes the kneecap (patella), and replacing them with precision-engineered implants made of metal and high-grade plastic.
These components mimic the movement of a natural knee joint and are designed to last for many years.
At Chelsfield Park, our surgeons use the latest imaging technology and surgical techniques to ensure accuracy and alignment, which helps maximise mobility and comfort after surgery.
Do I need private knee replacement surgery?
Knee replacement may be recommended when conservative treatments such as physiotherapy, medication, or joint injections no longer provide adequate relief. Common signs that surgery may help include persistent pain, swelling, instability, or stiffness that limits walking, climbing stairs, or everyday activities.
By choosing private care at Chelsfield Park Hospital, you’ll have access to rapid assessment, diagnostic imaging (including X-ray and MRI), and an in-depth consultation with a consultant orthopaedic surgeon. Together, you’ll discuss whether knee replacement is the right option for you and, if so, create a personalised plan for your treatment and recovery.
What causes damage to your knees?
The most common cause of knee joint damage is osteoarthritis, a degenerative condition that wears away protective cartilage, leading to pain and stiffness.
Other causes include rheumatoid arthritis, post-traumatic arthritis (after injury or fracture), and long-term wear from overuse or sports activity.
Certain factors such as age, genetics, weight, and previous injuries can increase the likelihood of joint deterioration. Your consultant will evaluate your condition and recommend the most suitable treatment based on imaging results and lifestyle needs.
What are the different types of knee replacement?
There are two main types of knee replacement surgery:
Total knee replacement: The entire joint is replaced with artificial components, suitable for widespread arthritis or severe damage
Partial (unicompartmental) knee replacement: Only the affected part of the knee is replaced, preserving healthy bone and tissue for a faster recovery
Your surgeon will recommend the most appropriate option depending on the extent of joint damage. In both cases, our aim is to restore smooth, natural movement with minimal discomfort.
What happens at a total knee replacement consultation?
During your initial consultation, your orthopaedic consultant will review your symptoms, examine your knee, and assess your range of motion.
Diagnostic imaging such as X-rays or MRI scans may be arranged to confirm the severity of joint wear.
Your consultant will then explain in detail about the surgical procedure, recovery expectations, and potential risks, ensuring you have all the information you need to make an informed decision.
This one-to-one appointment also provides an opportunity to discuss alternative treatments or rehabilitation programmes if full replacement is not yet necessary.
What happens during knee replacement surgery?
Knee replacement is performed under general or spinal anaesthetic and usually takes one to two hours. Your surgeon will make a precise incision at the front of the knee, remove the damaged surfaces, and replace them with durable prosthetic implants.
Once the new joint is in place, the incision is closed and covered with a sterile dressing. Most patients are encouraged to begin gentle movement with a physiotherapist the same day or the following morning to aid recovery and circulation.
How long does a knee replacement take?
The surgical procedure itself typically lasts around 90 minutes, though preparation and recovery time in theatre may extend your stay to around two to three hours. Most patients spend two to three nights in hospital before returning home with a physiotherapy plan and mobility aids.
How long does it take to recover from a knee replacement?
Recovery varies by individual, but most patients can expect significant improvement within six to twelve weeks. You’ll work closely with a physiotherapist to restore strength, balance and flexibility.
Many people return to light daily activities, including driving, after six weeks, and experience continued improvement for up to a year after surgery. Our comprehensive aftercare includes follow-up appointments to monitor your healing and ensure your new knee is functioning as expected.
How much does a private knee replacement cost?
The cost of a private knee replacement at Chelsfield Park Hospital depends on various factors, including which type of knee replacement you are having, which implant you choose, and which surgeon you have treatment with.
Your consultant will provide a personalised quote after your assessment, including all hospital, surgeon, anaesthetist, and aftercare fees.
We offer fixed-price packages with transparent costs and finance options for self-pay patients, allowing you to spread payments over time. Many major health insurers also cover joint replacement surgery.
