Knee Arthroscopy

This procedure is commonly known as ‘key-hole surgery’ because it involves a camera attached to a thin  telescope, being inserted into the knee joint through small incision. This allows the surgeon to look inside the knee joint and identify any problems, small instruments can also be inserted via a second incision to treat some problems.

  • Meniscal tears
  • Removal of loose bodies
  • ‘Tidy up’ of worn cartilage

It is the commonest knee operation performed.

What is involved?

The surgery is usually carried out under general anaesthetic as a day procedure. A ‘straight forward’ knee arthroscopy takes about 20 minutes but this time will increase the more complex the problem within the knee. The knee is injected with local anaesthetic at the end of the operation – this is to help minimise post-operative pain and the incisions are closed with steristrips.


Microfracture is a procedure to treat chondral defects; this allows a blood clot to form which matures into fibrocartilage over time.  Small perforations are made in the bone to stimulate bleeding.


Menisectomy is the commonest procedure performed when performing a knee arthroscopy. It involves removing the torn meniscus which can cause mechanical symptoms of ‘clicking’ and ‘locking’.

Sometimes it is possible to repair the meniscus, this is performed with internal stitches used to stitch the tear back.

Recovery and Rehab

You will be seen by a physiotherapist after your surgery who will help you mobilise and you will be able to walk out of hospital 3-4 hours after your operation. You will have post-operative physiotherapy for a few weeks after and your mobility will improve daily.

  • You will be able to drive 5-7 days after
  • You will need around 1-2 weeks off work depending on your job
  • Your knee should be back to normal 6-8 weeks after your surgery.

I want to thank Mr. Datta for taking such good care of me during both hip replacement procedures. It was my first major surgery and he helped calm my nerves. Both surgeries were successful and the after care was excellent. I am now completely pain free and able to do things I was not able to do for a number of years.

I must say my overall experience at Spire under Mr Datta was first class and I am very grateful to all involved

My care and treatment has been excellent. From my first consultation through to my surgery, I have been kept well informed and have had all the information I’ve needed to ensure the surgery went well and that I make a speedy recovery. I would highly recommend Mr Datta.

Mr King

I had a total knee replacement done and had the best care. Yes did experience a long wait to go to surgery but that's expected in most hospitals. Was in for 3 days and couldn't fault the care, nurses and cleanliness of the hospital. Lovely food. One nurse in particular always managed to make me smile
