Procedure guide · Orthopaedic surgery
Knee arthroscopy is surgery that uses a tiny camera, inserted through small cuts, to look inside the knee and treat problems with small instruments. MedlinePlus notes that most people go home the same day. It is generally used for mechanical problems such as torn cartilage or loose fragments, and an orthopaedic surgeon decides whether it will help your knee.
What is knee arthroscopy?
The surgeon makes two or three small cuts and fills the joint with sterile salt water so it can be seen clearly. MedlinePlus lists what can be treated this way:
- a torn meniscus, the cartilage cushion between the bones, which can be repaired or trimmed
- torn or damaged cruciate ligaments
- loose or broken pieces of cartilage, and some cartilage defects
- an inflamed joint lining (synovium)
- a misaligned kneecap, some fractures and Baker cysts
Anaesthesia can be local, spinal, general or a nerve block, depending on the procedure and your surgeon.
Who may be considered for knee arthroscopy?
MedlinePlus says arthroscopy is usually recommended for mechanical or structural problems. Examples are torn tissue, loose fragments that make the knee catch, and lining inflammation that has not settled with other care.
It also notes that if you have arthritis, you may still have arthritis symptoms after surgery. That is why a surgeon looks carefully at what is causing your pain before suggesting it. Your surgeon decides whether arthroscopy, physiotherapy or another treatment fits your knee.
Which reports does a knee surgeon usually ask for?
Ask the hospital whether it needs:
- an MRI scan of the knee with the images
- standing knee X-rays, which help show arthritis
- a description of symptoms such as locking, catching or giving way
- how and when any injury happened
- treatments already tried
- a medicine list, including blood thinners
How do I plan a knee arthroscopy trip?
This is often one of the shorter orthopaedic trips, but plan for more than the procedure day. Allow time for consultation and checks, the arthroscopy, a wound review and early exercises. MedlinePlus says simple repairs often recover quickly, while more complex repairs may need crutches or a brace for several weeks. Your surgeon tells you which applies and when you may fly.
MedlinePlus advises that blood thinners may need to be paused beforehand and that fasting is usually needed before surgery. Confirm these instructions with the hospital in writing. Ask for photos or a report of what was found and done inside the knee. Your physiotherapist at home will need it.
What should I ask the hospital before booking?
- What do you expect to find and treat inside my knee?
- Will the meniscus be repaired or trimmed, and how does that change my recovery?
- Will I need crutches or a brace?
- Which anaesthetic do you plan to use?
- Will I receive photos and a written operation report?
- Which exercises should I start straight away?

Questions people ask
Will arthroscopy help my arthritis?
MedlinePlus notes that people with arthritis may still have arthritis symptoms after knee arthroscopy. It is mainly used for mechanical problems such as torn cartilage or loose fragments. Ask your surgeon to explain what they expect the procedure to achieve for your knee.
Is a meniscus repair different from trimming?
Yes. A repair stitches the torn cartilage so it can heal, while trimming removes the damaged part. MedlinePlus lists both as options. A repair may mean a longer recovery with more restrictions. Your surgeon decides which is possible once they see the tear.
