Knee pain is a very common complaint. But while most people have pain now and again, or pain that comes and goes, some people struggle through life with chronic and severe knee pain.

If this sounds like you, you don't have to put up with it. There are many treatments available that can help you to reduce, manage or even eliminate the pain in your knee, as well as targeting other symptoms such as stiffness or swelling.

At Shirley Oaks Hospital in Croydon, we have a team of experienced orthopaedic consultants who specialise in problems of the knee. Our experts are ready and waiting to help you. Simply call or book online today.

"The symptoms we most commonly see at our knee clinic in Croydon are pain, swelling, stiffness, locking and giving way of the knee," explains Consultant Orthopaedic Surgeon Mr Christian Kinmont. "Virtually all knee conditions are variations of these five main problems."

Sports injuries and general wear-and-tear are the two most common causes of knee pain.

If you injure your knee, it may be painful initially but will then often improve over time. If your symptoms don't improve, you may need further investigations and expert advice. It might be that lasting damage has been done and you need corrective treatment.

Common injuries to the knee include a torn anterior cruciate ligament (ACL) and a torn meniscus.

Similarly, if you're suffering with wear and tear in the knee, you may at first only have mild symptoms. As the damage to the joint increases, pain and stiffness in the knee usually becomes worse, even limiting your mobility. Where symptoms are noticeable and having a significant effect on your quality of life, you may want to explore further treatment options.

Osteoarthritis is the name given to wear and tear of the knee joint. This is the most common form of arthritis, though we also see patients with rheumatoid arthritis.

At Shirley Oaks Hospital, our consultant knee surgeons treat all knee conditions, helping to get people out of their pain and stiffness and back to better movement, function and strength in the knee once more. Whether you're suffering from arthritis in the knee, damage to a ligament or meniscus or incorrect alignment of the joint itself, they would be delighted to help you.

When you meet with your consultant at Shirley Oaks, they will take your medical history and ask you about your symptoms. They will ask you questions like:

  • What symptoms do you have?
  • When did you first notice these symptoms?
  • If you have any pain in your knee, can you describe it?
  • Have your symptoms been getting worse?
  • Have you tried any treatments already? If so, did they help?
  • What things can you no longer do because of your symptoms?

Your consultant will examine your knee, and possibly your hip, back or lower leg if they suspect a problem in any of these places, as pain can sometimes be referred from a problem in one of these areas.

Depending on your particular symptoms and the physical examination of your knee, you may be referred for additional tests or investigations. This may be an X-ray of your knee, an ultrasound, CT scan or MRI scan. All of these are available on-site and can be easily arranged for you if required.

Once the results of any tests are back and your consultant has been able to confirm a diagnosis, they will discuss the results with you and explain suitable treatment options.

For many people who are concerned about knee pain, investigation will show there is nothing serious wrong with their knee and they should expect their symptoms to improve over time. This can be a real relief for people to hear, especially if they've been worrying about it for some time.

There are certain circumstances where knee surgery will be the best option, which is typically if there is a specific injury - such as a torn ligament - that can be directly repaired during an operation.

However, most people with knee pain will not need surgery, or at least not straight away. We try to make sure we have exhausted non-invasive options first. For example, we might recommend joint injections, such as cortisone injections or even platelet-rich plasma (PRP) injections. These can reduce your pain and other symptoms to the point where you're happy to live with it.

If these non-surgical methods aren't effective, we'll start to consider surgery. However, a knee replacement operation is a major procedure and we will only recommend it if it's the best choice for you.

"The main reason for knee replacement surgery is when someone's quality of life is severely affected due to the pain, stiffness or sometimes deformity in their joint," says Mr Kinmont. "It's a major operation with a long recovery, so we have to be sure that the pain is bad enough to justify the process. We always want to feel like we've exhausted other options first."

Of course, many people will only come to Mr Kinmont when they have already tried treatments such as physiotherapy, painkillers, anti-inflammatories and injections. "In that case, it's clear the problem is severe and we will begin to discuss knee surgery."

Mr Kinmont lists the most common knee procedures that he performs as:

  • knee replacement surgery (for severely arthritic joints)
  • ligament reconstruction (most commonly for anterior cruciate ligament injuries)
  • arthroscopic procedures (most commonly for meniscal tears)
  • joint injections (for an inflammatory swollen knee)

Knee replacement surgery

Knee replacement surgery significantly reduces knee pain and improves mobility in your knee. There are two main types of knee replacement surgery: total and partial. The type you undergo will depend on your condition.

During partial knee replacement surgery, the damaged part of your joint will be removed and replaced with an artificial component (also known as a prosthesis). During total knee replacement surgery, your consultant surgeon will remove the damaged ends of your femur (thigh bone) and tibia (shin bone) and replace them with a prosthesis. The base of your patella (kneecap) might also be removed and replaced, but this will depend on the condition of your knee.

Anterior cruciate ligament (ACL) reconstruction surgery

ACL reconstruction surgery can repair or replace a torn anterior cruciate ligament (a major ligament in your knee). ACL damage is often caused by a traumatic accident when playing sport. ACL reconstruction helps reduce knee pain and restore function to your knee, allowing you to continue to live an active lifestyle and play the sport you love.

Knee arthroscopy

A knee arthroscopy is a form of keyhole surgery. It can diagnose and treat knee problems that cause chronic knee pain. During knee arthroscopy surgery, your orthopaedic consultant will insert an arthroscope (a thin tube with a camera attached to the end of it) through a small incision made in your knee. This will allow your consultant to examine the inside of your knee and confirm the cause of your pain.

If you require treatment arthroscopically, your Orthopaedic Surgeon will make more incisions in your knee to insert surgical instruments and carry out the treatment you require.

People choose to come to us for knee surgery for a number of reasons. Whether you live in Croydon itself, elsewhere in Surrey or much further afield, when you choose Shirley Oaks for your knee treatment you will benefit from:

Rapid access to an expert

Knee problems can have a big impact on everyday life and you'll undoubtedly want to get things treated and resolved as soon as possible. With a number of leading knee experts on-site at any one time, we'll be able to book an appointment for you without delay, so that you can get started with any treatment necessary sooner.

With over 4 million patients on NHS waiting lists, it's important to know that you could have your definitive care far sooner and also at a time of your choosing. Many people also prefer the security of having surgery on a green site which is Covid-free and also MRSA-free.

Excellent patient satisfaction rates

In an independent survey, over 97.6% of people we'd treated said they were likely or highly likely to recommend Shirley Oaks Hospital to their friends and family. We're grateful for this feedback and continue to focus on providing the highest level of care for every person we treat.

A personal approach from start to finish

Everybody's knees are shaped slightly differently, and a bespoke approach to treatment ensures any treatment you receive is optimal for your specific condition and biomechanics. With our state-of-the-art facilities and a highly experienced team, we can treat you properly and get you back to better knee health sooner.

Remote consultations available

While consultations are routinely carried out in person at Shirley Oaks, we can also offer remote consultations by telephone or online video call if you prefer.

Comprehensive support and aftercare included

After any kind of knee surgery, it's important you receive the right support and guidance throughout your recovery. Our dedicated physiotherapy team will support you throughout your time with us, helping you regain strength, mobility and function in your knee safely and at a sensible pace.

"Patients are assessed preoperatively to ensure that they have a clear plan for their rehabilitation after the operation," explains Mr Kinmont. "We offer physiotherapy seven days a week. It helps to optimise recovery."

Implant availability

Many NHS trusts limit the use of more expensive ceramic implants to younger patients (in some cases under 55s only). At Shirley Oaks Hospital we will always choose a bespoke implant, which will be suitable for your lifestyle needs and bone quality, rather than just treating you by your age.

Multidisciplinary team

From experienced consultant orthopaedic surgeons to physiotherapists, nurses, podiatrists, occupational therapists and radiologists, we have the expertise to ensure you receive the best treatment for your specific knee condition and optimised rehabilitation and recovery following treatment. In contrast to many NHS units, we offer either remote or face-to-face physiotherapy, this is particularly important when recovering from a knee replacement.

If you're ready to take control of your knee pain, book online or give us a call today and we'll get you booked in to see one of our specialists.
