Information about COVID-19 (Coronavirus)

On 11 March 2020 the World Health Organization confirmed COVID-19 (coronavirus) has now spread all over the world (this means it is a ‘pandemic’). Hospitals have very robust infection control procedures, however, it is impossible to make sure you don’t catch coronavirus either before you come into the hospital or once you are there. You will need to think carefully about the risks associated with the procedure, the risk of catching coronavirus while you are in hospital, and of not going ahead with the procedure at all. Your healthcare team can help you understand the balance of these risks. If you catch the coronavirus, this could affect your recovery and might increase your risk of pneumonia and even death. Talk to your healthcare team about the balance of risk between waiting until the pandemic is over (this could be many months) and going ahead with your procedure.

Please visit the World Health Organization website: for up-to-date information.

Information about your procedure

Following the Covid-19 (coronavirus) pandemic, some procedures have been delayed. As soon as the hospital confirms that it is safe, you will be offered a date. Your healthcare team can talk to you about the risks having your procedure if you coronavirus.

It is then up to you to decide whether to go ahead or not. The benefits of the procedure, the alternatives and any complications that may happen are explained in this leaflet. If you would rather delay the procedure until you feel happy to go ahead, or if you want to cancel, tell the healthcare team.

Coronavirus spreads easily from person to person. The most common way that people catch it is by touching their face after they have touched anyone or anything that has the virus on it.

Wash your hands with alcoholic gel or soap and water when you enter the hospital, at regular intervals after that, and when you move from one part of the hospital to another.

Even if you have had the first or both doses of a Covid vaccine, you will still need to practise social distancing, hand washing and wear a face covering when required.

If your healthcare team need to be close to you, they will wear personal protective equipment (PPE). If you can’t hear what they are saying because of their PPE, ask them to repeat it until you can. Chairs and beds will be spaced apart.

You may not be allowed to bring anyone with you into the hospital but they may be allowed to wait outside or in the car.

Your procedure is important and the hospital and health professionals looking after you are well equipped to perform it in a safe and clean environment. Guidance about coronavirus may change quickly ─ your healthcare team will have the most up-to-date information.

What is an arthroscopy of your knee?

Knee with a tear in the lateral meniscus

An arthroscopy (keyhole surgery) allows your surgeon to see inside your knee using a camera inserted through small cuts on your skin. Your surgeon can diagnose problems such as a torn cartilage (meniscus), ligament damage and arthritis.

They may be able to treat some of these problems using special surgical instruments, without making a larger cut.

Your surgeon has recommended an arthroscopy of your knee. However, it is your decision to go ahead with the operation or not.

This document will give you information about the benefits and risks to help you to make an informed decision. If you have any questions that this document does not answer, it is important that you ask your surgeon or the healthcare team.

Once all your questions have been answered and you feel ready to go ahead with the procedure, you will be asked to sign the informed consent form. This is the final step in the decision-making process. However, you can still change your mind at any point before the procedure.

What are the benefits of surgery?

The aim is to confirm exactly what the problem is and for many people the problem can be treated at the same time. The benefit of keyhole surgery is less pain afterwards and, for some people, a quicker recovery.

Are there any alternatives to surgery?

Problems inside your knee can often be diagnosed using a magnetic scan (MRI scan) but you may then need an arthroscopy to treat the problem.

Your surgeon will discuss with you having a scan before the arthroscopy.

Physiotherapy and anti-inflammatory painkillers such as ibuprofen can sometimes prevent or delay the need for an arthroscopy.

What will happen if I decide not to have the operation?

Damage inside your knee does not usually heal without treatment, although sometimes your knee will become less troublesome with time or after a course of physiotherapy.

If you have a torn cartilage, the tear can sometimes move out of place and cause your knee to lock. If your knee does not unlock again, you will need an urgent arthroscopy.

What does the operation involve?

If you are female, the healthcare team may ask you to have a pregnancy test as some procedures involve x-rays or medications that can be harmful to unborn babies. Sometimes the test does not show an early-stage pregnancy so let the healthcare team know if you could be pregnant.

The healthcare team will carry out a number of checks to make sure you have the operation you came in for and on the correct side. You can help by confirming to your surgeon and the healthcare team your name and the operation you are having.

Various anaesthetic techniques are possible. Your anaesthetist will discuss the options with you. You may also have injections of local anaesthetic to help with the pain after the operation. The operation usually takes 30 to 45 minutes.

Your surgeon will examine your knee ligaments while you are under the anaesthetic and your muscles are completely relaxed. They will insert a small camera through one or more small cuts around your knee.

Your surgeon will examine the inside of your knee for damage to the cartilages, joint surfaces and ligaments. It is usually possible for your surgeon to trim or repair a torn cartilage without needing to make a larger cut. Your surgeon will close your skin with stitches or sticky strips.

If you have torn your anterior cruciate ligament (ACL), you may need a reconstruction operation. This is a larger procedure but it can often be performed by an arthroscopy. Your surgeon will discuss this with you beforehand.

What should I do about my medication?

Make sure your healthcare team knows about all the medication you take and follow their advice. This includes all blood-thinning medication as well as herbal and complementary remedies, dietary supplements, and medication you can buy over the counter.

What can I do to help make the operation a success?

If you smoke, stopping smoking now may reduce your risk of developing complications and will improve your long-term health.

Try to maintain a healthy weight. You have a higher risk of developing complications if you are overweight.

Regular exercise should help to prepare you for the operation, help you to recover and improve your long-term health. Before you start exercising, ask the healthcare team or your GP for advice.

An arthroscopy of the knee

If you have not had the coronavirus (Covid-19) vaccine yet, ask your healthcare team if this can be done before your operation. This will reduce your risk of serious illness related to Covid-19 while you recover.

What complications can happen?

The healthcare team will try to reduce the risk of complications.

Any numbers which relate to risk are from studies of people who have had this operation. Your doctor may be able to tell you if the risk of a complication is higher or lower for you.

Some complications can be serious and even cause death (risk: 1 in 5,000).

You should ask your doctor if there is anything you do not understand.

Your anaesthetist will be able to discuss with you the possible complications of having an anaesthetic.

General complications of any operation

  • Bleeding during or after the This can cause a small lump under your wound that usually settles within a few weeks. If you get a lot of blood in your knee (a haemarthrosis), it will be swollen and painful (risk: 1 in 1000). You may need another operation to wash the blood out.

  • Severe pain, stiffness and loss of use of your knee (complex regional pain syndrome). The cause is not known. You may need further treatment including painkillers and Your knee can take months or years to improve. Sometimes there is permanent pain and stiffness.


A recent Covid-19 infection increases your risk of lung complications or death if you have an operation under general anaesthetic. This risk reduces the longer it is since the infection. After 7 weeks the risk is no higher than someone who has not had Covid-19. However, if you still have symptoms the risk remains high. The risk also depends on your age, overall health and the type of surgery you are having.

You must follow instructions to self-isolate and take a Covid-19 test before your operation. If you have had Covid-19 up to 7 weeks before the operation you should discuss the risks and benefits of delaying it with your surgeon.

Consequences of this procedure

  • Your surgeon may inject painkillers into your knee to help reduce the pain. The healthcare team will give you medication to control the pain and it is important that you take it as you are told so you can move about as advised.
