So, back from seeing the surgeon and I’m getting an Arthroscopy to repair the damage in my knee. A perfect time to have a look at what this entails. All this information has been taken from the NHS Choices website.
An arthroscopy is a type of keyhole surgery used both to diagnose and treat problems with joints.
The procedure is most commonly used on the knees, ankles, shoulders, elbows and wrist.
An arthroscopy might be recommended to look at the inside of the joints if imaging tests have been performed and you have problems such as swelling or stiffness.
As well as allowing a surgeon to look inside a joint, an arthroscopy can also be used to treat a range of problems and conditions. For example, it can be used to:
- repair damaged cartilage
- remove fragments of loose bone or cartilage
- treat frozen shoulder
What happens during an arthroscopy?
A piece of equipment called an arthroscope is used during an arthroscopy. An arthroscope is a small, metal tube about the length and width of a drinking straw. Inside, a bundle of fibre optics act as both a light source and a camera. Images are sent from the arthroscope to a video screen or an eyepiece so that the surgeon is able to see the joint.
It is also possible for tiny surgical instruments to be passed through an arthroscope to allow the surgeon to treat certain conditions.
The arthroscope is inserted into a small incision next to the joint. More small incisions may also be made to allow an examining probe or surgical instruments to be inserted.
An arthroscopy is usually carried out under general anaesthetic. Although, in some cases a spinal or local anaesthetic is used.
An arthroscopy is usually performed as a day case procedure, which means the person being treated is able to go home on the same day as the surgery.
An arthroscopy is usually a day case procedure which lasts between 15 to 45 minutes. More extensive surgery can sometimes take up to 2-3 hours.
Preparing for surgery
Before having an arthroscopy, you will usually be given an appointment to attend a pre-admission clinic.
During your appointment your general fitness will be assessed to ensure that you are ready for surgery. You will also be given information about issues such as:
- what and when you are allowed to eat and drink on the day of the surgery
- whether you should stop or start any medications before surgery
- how long it will take for you to recover from surgery
- whether you will need to do rehabilitation exercises after surgery
The surgical team will explain the benefits and risks that are associated with having an arthroscopy. You will also be asked to sign a consent form to confirm that you agree to have the operation and that you understand what is involved, including the risks and benefits.
The arthroscopy operation
An arthroscopy is usually carried out under general anaesthetic, although occasionally it can be performed under spinal anaesthesia, or with local anaesthetic. Your anaesthetist (a doctor trained in giving people anaesthetic) will explain which type of anaesthetic is most suitable for you. In some cases you may be able to express a preference.
If you have a local anaesthetic your joint will be numbed so that you do not feel any pain. However, you may still feel some sensations during the procedure, such as a mild tugging, as the surgeon works on the joint.
Anti-bacterial fluid is used to clean the skin over the affected joint and a small incision, a few millimetres long, is made to enable the arthroscope to be inserted.
One or more additional incisions will also be made so that an examining probe, or other instruments can be inserted.

The surgeon may fill the joint with a sterile fluid to expand it and make it easier to view. They will be able to see inside your joint using an eyepiece or a video screen. If possible, during the procedure, they will repair any damaged areas and remove any unwanted tissue.
After the procedure, the arthroscope plus any attachments are removed along with any excess fluid from the joint. The incisions are closed using paper tape or stitches and covered with a sterile dressing.
Recovering from an arthroscopy
Your recovery from an arthroscopy can vary depending on the type of surgery, your general health and the type of work that you do.
After the operation
After your arthroscopy, you will be taken to a room to recover from the effects of the general anaesthetic, if you have had one.
You may experience some pain in the joint. If you do, tell a member of the hospital staff who will be able to give you painkillers.
Most people who have an arthroscopy are able to leave hospital either on the day of the surgery or the following morning. Before leaving hospital, you may have an appointment with a physiotherapist to discuss exercises for you to do at home.
You may be advised to elevate the joint and apply ice packs to help with swelling. Depending on the surgery, you may be given special pumps or compression bandages to help improve blood flow.
It is likely that you will feel tired and light-headed after having a general anaesthetic, so you will need to ask a responsible adult to take you home and to stay with you for the first 24 hours following surgery. Most people will recover from the effects of the anaesthetic within 48 hours.
Any dressings will need to be kept as dry as possible, so you will need to cover them with a plastic bag when having a bath or shower. If your dressings do get wet or fall off, they will need to be replaced.
As a general rule, most children can return to school within a week of having surgery and most adults are able to return to work within three to six weeks.
You will be able to drive again once it is safe for you to make an emergency stop without damaging the affected joint. Depending on the procedure, this may be a few weeks or several months after surgery. Your surgeon will be able to give you a more specific recommendation.
Your surgeon will also be able to advise you about how long it will be before you can undertake strenuous physical activities, such as heavy lifting and sport. For most people this will be around six to eight weeks after surgery.
You will usually be asked to attend a follow-up appointment four to six weeks after the operation to discuss the results of the surgery, your recovery and any additional treatment that you may require.
