At Practice Plus Group, the average waiting time for private knee surgery is 4-6 weeks from booking enquiry to having your surgery. We also understand that it’s not just about how quickly you can have surgery, but having your treatment at a time that works for you. We’ll work with you to arrange your surgery around your needs and availability, so you can plan your treatment with confidence.
What is knee replacement surgery?
Knee replacement surgery involves replacing a damaged knee with an artificial joint shaped to allow continued motion of the knee. This is a common operation that can help to relieve pain and restore mobility.
During the procedure, the damaged cartilage is removed and replaced with metal implants. These are often cemented into the bone. A plastic spacer is then inserted between the metal components to create a smooth surface.
When should I seek treatment for my knee?
For many people, only a knee replacement can relieve pain.
If you experience any of the following symptoms you may need knee replacement surgery:
severe or increasing pain or stiffness
chronic knee inflammation and swelling
knee deformity and loss of function
pain at rest and pain at night
‘bowing’ of the leg
non-steroidal anti-inflammatory drugs no longer provide relief from pain.

“It was fantastic: it all went very well and I was delighted that I had the opportunity to have surgery and be back home the same day. Everyone feels better recovering in their own home. I am also very happy not to have a general anaesthetic, as I have had them several times and did not like the after effects.
“Having met the team, I knew they were kind, professional and supportive. I was relaxed and confident about the surgery and looking forward to being pain-free.”

Suffering from knee pain?
If you’re experiencing knee pain, try our knee surgery suitability quiz. It will give you an idea of whether you’d benefit from booking a consultation with one of our knee specialists.
The type of treatment you need will depend on the damage sustained to your knee. There are several different types of treatment available to suit your needs.
Total knee replacement surgery is for people whose knees are severely damaged by arthritis or injury. It’s suitable for those who find it difficult to perform simple daily activities like walking or climbing stairs. It’s also for those who might be experiencing long term knee pain when sitting or lying down.
Partial knee replacement surgery involves replacing only the diseased or damaged joint surfaces in the knee with metal and plastic components.
Partial knee replacement surgery may be suitable for people suffering from osteoarthritis.
Although similar to a total knee replacement, this procedure doesn’t interfere with healthy cartilage or bone. Instead, the implant only replaces damaged parts of the knee. The recovery period lasts around three weeks.
Keyhole surgery – sometimes called ‘knee arthroscopy’ – is a minimally invasive procedure in which the surgeon makes two very small holes on either side of the kneecap.
One of the holes is used to pass the surgical instruments into the knee, while the other is for the arthroscope. This is a thin, flexible tube containing a light and a camera. This provides the knee surgeon with a clear image of the inside of the knee joint.
Knee resurfacing is a very similar procedure to knee replacement, but with a slight difference:
Knee replacement surgery replaces the entire knee joint (outer, inner and kneecap) with an artificial joint, whereas during knee resurfacing surgery (sometimes referred to as Patella resurfacing), your orthopaedic surgeon will aim to preserve any healthy bone you have in the compartments of your knee, only replacing the damaged sections.
Total knee replacements are a very successful procedure. However, before operating, other measures are usually tried first. These include:
rest or reduced activity
pain-relieving medication
anti-inflammatory medication (if no contra-indications)
physiotherapy
weight loss.
A steroid injection can give temporary relief, while some patients may benefit from minor arthroscopic (keyhole) procedures.
Who is knee replacement for?
Knee replacements can be needed by people of any age, however, age, genetics and previous injury increase the likelihood of needing a joint replacement.
Older people are more likely to suffer from conditions like rheumatoid arthritis that lead to a breakdown of the knee tissue. For sportspeople, a sudden change of direction and general overexertion can cause knee ligaments to fray or rupture. In both cases, knee replacement surgery is often needed to repair wear and tear of the knee joint.
What are the signs that I need knee replacement surgery?
An x-ray may reveal a number of issues such as:
bone touching bone with no remaining cartilage
extra bone lumps around the joint (osteophytes)
cavities or cysts in the bone (geodes)
hardening of arthritic bone (sclerosis).
If you experience any of these knee symptoms and you are not treated, you run the risk of the following problems:
weakened muscles and ligaments of the knee
deformity of the area outside the knee joint
limited mobility due to chronic knee pain and loss of function

The first step is a private knee consultation. You’ll meet your dedicated orthopaedic surgeon and anaesthetist for a pre-operative assessment appointment. This will include x-rays of the affected knee.
This is your opportunity to talk about your general health and medical history, ask questions and prepare yourself for the procedure. Once the clinician has assessed you, you’ll be given a date for surgery.
Try to stay active before your surgery to increase strength and speed up the recovery process. Find more tips on preparing for surgery here.
You’ll be given a general anaesthetic so you’ll be asleep during the procedure. During the surgery itself, the worn ends of the bones in your knee joint are removed and replaced with metal and plastic parts. This is called a prosthesis specially made to fit your knee. The type of surgery you have (total or partial replacement) will depend on how damaged your knee is.
Knee replacements are called knee arthroplasty and are a resurfacing procedure. In osteoarthritis, trauma and inflammatory arthritis, the smooth, low-friction, cartilage that cushions the joint is lost. In knee replacement surgery the damaged surfaces are removed and the thigh bone surface is covered with a smooth metal dome.
The shin bone surface is covered with a metal tray. A medical-grade plastic spacer is then fitted which functions as the smooth bearing surface on which the bone glides. The patella can also be resurfaced with a plastic button.
Knee replacement surgery time can take between one and two hours and is usually carried out with a spinal anaesthetic. Patients can also have a short-lasting intravenous sedative, so they snooze during the procedure, but recovery is enhanced having avoided a full general anaesthetic.
With any major surgery, there is a small risk of complications. These are always discussed in detail with you beforehand. Programmes of care and hospital routines are regularly revised to minimise these occurrences. This means issues such as pulmonary embolism (blood clot) and deep infection are rare.
Other risks of knee replacement surgery are:
infection
deep vein thrombosis (DVT)
nerve damage
stiffness and issues with the artificial joint.
After a total knee replacement, the knee will always feel a little mechanical. Proprioception (natural stability) can be reduced in some situations but a good functional range of movement is the norm. For the vast majority of patients, a knee replacement is the most effective procedure for providing pain relief for an arthritic knee.
The main benefit of private knee surgery is the reduced waiting time. The NHS currently aims to get patients into surgery within 18 weeks of their initial consultation. However, the COVID pandemic has meant that some patients are facing greatly increased waiting times. The current waiting time for knee replacement surgery at Practice Plus Group is between two and four weeks.
At Practice Plus Group, we follow the Enhanced Recovery Pathway (ERP). This is a modern, evidence-based approach that helps you speed up your recovery following knee replacement surgery.
The ERP champions the many advantages of day surgery knee replacement. With this support, you will be mobile enough to go home one or two days after your operation. Some people are able to return home on the day of surgery.
After surgery in the recovery room, our physiotherapists begin working closely with you within hours of your joint replacement surgery. You will be encouraged to be on your feet to prevent blood clots and encourage faster healing. The length of stay at our private hospitals can be significantly shorter as a result.
Early mobilisation and a return home reduces the risk of deep vein thrombosis and infections. It can also make patients feel more comfortable. With this support you will be mobile enough to go home two to four days after your operation. You will be given exercises after knee replacement surgery and instructions on how to use mobility aids such as crutches and sticks.
You will need to rest when you return home and you are likely to feel tired in the first six weeks. Pain relief (analgesia), icepacks, elevation and a programme of rehabilitation are normal. By 10 to 12 weeks most patients are doing well, though knee replacements often improve for up to 18 months after surgery.
Our expert on preparing for knee replacement surgery:
“Patients need to make sure they’re eligible for surgery. Keeping themselves in good physical condition can go a long way to ensuring their surgery takes place on the scheduled time and date.”
Alongside cycling and walking, your physio will provide a list of the best exercises for you to do following your knee operation. They will devise an exercise program designed specifically for your needs. It will likely contain low-impact activities such as:
Straight leg raises
While lying flat on a bed, keep your affected leg straight and raise it about 12 inches off the bed. Hold it for up to five seconds before lowering back down.
Ankle pumps
These are a great way of reducing the swelling in your affected leg while strengthening muscles. While lying flat on the bed, pump your feet up and down while hinging at the ankle. You can also rotate your feet clockwise and anti-clockwise. These exercises can be done multiple times a day.
Wall slides
Place a rolled up towel between your legs and stand up straight with your back against a wall. Keeping your hands on your hips, slowly slide down the wall under you’re in a slight squat position. Hold for a few seconds and slide back up. Repeat this exercise 10 times.
The price of knee replacement surgery can vary depending on several factors. These include the location of the hospital, the type of surgery, the consultant and the chosen healthcare provider. As a ballpark figure, you can expect to pay anything from £8,000-18,000 for your knee surgery.
At Practice Plus Group the cost of our knee replacement surgery is £13,799 plus £145 for the consultation. This is around £2,000 cheaper than some of our closest competitors. This price includes everything, no hidden costs, no unexpected invoices after surgery, no post-op follow-up costs.

Your knee replacement operation questions answered

A knee replacement is an artificial knee joint that replaces the original worn, damaged joint. The new joint is designed to replicate a working knee joint, improving the patient’s mobility and quality of life.
While a total knee replacement sees the entire knee joint replaced with an artificial one, partial knee replacement generally retains a lot of the existing knee tissue.
Knee replacement is a major surgery but isn’t considered high-risk. In fact, the success rate is very high.
If you have any doubts or questions before knee replacement surgery, please don’t hesitate to get in touch with your orthopaedic surgeon.
According to an NHS survey from 2020, 75% of patients said they felt a lot better following their operation. 15% reported feeling a little better, while just 5% said they felt worse. 1
Aside from the high success rates for knee replacement surgery, there are many other benefits for patients to enjoy. Improved mobility and stability can allow you to return to some of the activities you enjoyed before your injury.
The other big advantage is simply a better quality of life. The ability to move about with more freedom and the absence of pain cannot be understated. This is also likely to have a positive effect on your mental health and wellbeing.
Knee replacement surgery doesn’t tend to be recommended before the age of 50. This, however, does depend on the severity of the damage to the knee and is sometimes necessary for younger people. The typical age of a knee replacement patient is between 50-80.
According to a report published by the British Medical Journal in 2019, the average age for people having a knee replacement in the UK is around 70 years of age.
Knee surgery can relieve the pain of arthritis, but unfortunately cannot cure it.
The operation itself isn’t painful as you’ll be under anaesthetic. Some pain and discomfort is likely in the hours and days after the operation. However, this is usually managed with prescribed pain relief and exercise.
The answer to this depends on a number of factors. The amount of pain you’re in should be taken into account, along with the amount of money you’re willing to spend. The value of a total knee replacement will also depend on the severity of the knee damage, your age, and the recommendation of your physio or doctor.
Artificial knee replacement implants are typically made from a combination of metal, plastic, and ceramic.
Every patient will recover at different rates. However, there are still some things you can do to help speed up the process:
– Walk frequently (when permitted by your doctor)
– Follow your doctor or physiotherapist’s exercises and advice
– Get plenty of sleep
– Eat a healthy, balanced diet.
The activities to avoid after a knee replacement are those that carry a high-risk of falling. Sports such as rugby, football and skiing should be avoided as these could cause damage to the new implant.
Activities involving a lot of running and jumping should also be avoided, as well as sitting for prolonged periods of time.
Everyone heals at different rates. Typically, knee replacement patients are able to drive again around six weeks after their operation or when they can press the pedals down fully without experiencing pain.
Once you’ve had your surgery, it’s important that you work to protect your new artificial knee joint. The following are some hints and tips for helping protect and strengthen your knee:
– Maintain a healthy weight to reduce the stress on your joints
– Strengthen the muscles around the knee
– Stay as flexible as possible to stop your muscles getting tight
– Maintain a healthy diet for your overall health.
It is strongly advised to attend all of your follow-up and physio appointments. This will help ensure you make a full recovery.
According to MyTribeInsurance, the average cost of a private knee replacement in the UK is £15,138.
Knee replacement, Emersons Green – excellent care throughout
I had a uni-knee replacement operation on 20th February and six weeks later I am very pleased with it. I had excellent care throughout my stay and everything matched or exceeded my expectations. Although paying for it myself was daunting I am glad I had the op and the certainty of a set fee made it less worrying. I would recommend Practice Plus at Emersons Green to anyone else who can afford not to wait for an NHS operation.
