Knee Arthroscopy - Meniscal Surgery
Knee arthroscopy is a minimally invasive "keyhole" procedure used to treat tears in the menisci—the "cushions" that absorb shock and stabilise the knee joint. This surgery is often recommended to relieve pain, reduce swelling, and restore normal knee function.
Following knee arthroscopy for meniscal surgery, you can expect a swift recovery, with most procedures completed within an hour. The minimally invasive approach involves only a few small incisions, resulting in less post-operative discomfort and quicker healing times. While you will need to take some precautions and follow a structured recovery plan, many patients are able to walk and use their knee almost immediately after the procedure. This approach aims to minimise disruption to your daily life while promoting a successful outcome.
The Procedure
Each knee has two menisci, which act as shock absorbers and stabilisers in the joint. When they are injured, they can cause pain and jamming in the knee, which prevents normal movement. Knee arthroscopy for meniscal surgery involves either repairing or removing the damaged section, depending on the tear's location, shape, and size.
This minimally invasive procedure is typically performed through two small cuts (1-2 cm) at the front of the knee. Sometimes, additional incisions are required to get a better view or access. The knee is filled with sterile fluid to create space, and a small camera is used to inspect and treat the damaged areas. The entire surgery, including anaesthetic, usually takes less than an hour. Most patients receive a general anaesthetic, while local anaesthetic is used to control post-operative pain. The incisions are closed with sutures, covered with a dressing, and then wrapped in a bandage to help reduce swelling.
In some cases, a knee brace is needed to restrict movement, giving the meniscus time to heal properly. If this is required, it will be fitted before discharge, with clear instructions on how to use it.
Recovery
Knee arthroscopy for meniscal surgery is usually performed as a day-case procedure, meaning patients can go home a few hours after surgery. The bandage stays on for 24 hours, while the dressing can remain for up to 2 weeks. Most patients are allowed to start using their knee immediately, but if movement restrictions are necessary, this will be explained before you leave the hospital.
Patients are typically seen at 2 weeks post-operation to check the healing and remove the sutures, with a follow-up appointment at 6-8 weeks to ensure pain is reducing and mobility is returning. Further check-ups may be scheduled if needed.
Simple painkillers are usually sufficient for the first couple of weeks, but it’s not unusual for swelling and discomfort to take 2-3 months to subside completely.
