Knee Arthroscopy Faq’s

Knee arthroscopy is a minimally invasive surgical procedure used to diagnose and treat problems within the knee joint. During the procedure, a small camera called an arthroscope is inserted into the knee through tiny incisions, allowing the surgeon to view the inside of the joint on a video monitor. This technique enables the surgeon to diagnose and treat a variety of knee conditions with less tissue damage compared to traditional open surgery.

Knee arthroscopy is performed to diagnose and treat a range of knee problems, including torn meniscus, damaged cartilage, ACL injuries, and loose fragments of bone or cartilage. It can also be used to remove inflamed synovial tissue or treat patella (kneecap) problems. The minimally invasive nature of the procedure often results in less pain and a quicker recovery compared to open surgery.

Preparing for knee arthroscopy involves several steps. You will need to undergo a preoperative assessment to ensure you are fit for surgery. This may include blood tests and imaging studies. You should inform Dr Martin of any medications you are taking, as some may need to be paused before the procedure. Fasting instructions will be provided, typically requiring you to avoid eating or drinking for several hours before surgery. Arranging for someone to drive you home after the procedure is also important.

Knee arthroscopy can be performed under local, regional, or general anaesthesia. Local anaesthesia numbs only the knee area, regional anaesthesia numbs the lower half of the body, and general anaesthesia puts you to sleep for the duration of the procedure. The choice of anaesthesia will depend on your overall health, the complexity of the procedure, and your preferences. Dr Martin and the anaesthesia team will discuss the best option for you.

The duration of knee arthroscopy varies depending on the complexity of the condition being treated. Typically, the procedure lasts between 30 minutes to an hour. However, the total time spent at the surgical facility will be longer due to preparation and recovery times.

Recovery from knee arthroscopy is generally quite rapid. You can expect some swelling and discomfort for a few days or weeks post-surgery, which can be managed with pain medications and ice therapy. Physiotherapy may play a role in recovery, helping to restore strength and mobility to the knee. Most patients can return to normal activities within a few weeks, although full recovery may take a few months.

While knee arthroscopy is generally safe, potential complications can include infection, blood clots, excessive swelling, and damage to blood vessels or nerves. These complications are rare, and Dr Martin will take steps to minimise these risks. It’s important to follow postoperative care instructions and attend follow-up appointments to monitor your recovery.

You may need crutches for a few days after knee arthroscopy to help you move around without putting too much weight on your knee. A knee brace may also be recommended to provide additional support and protect the knee during the initial healing phase. Dr Martin will provide specific guidance based on your individual needs.

Driving is typically not recommended immediately after knee arthroscopy, especially if you are taking pain medications that could impair your ability to drive. Most patients can resume driving within a week, provided they have regained sufficient strength and mobility in the knee and are no longer taking strong painkillers. Dr Martin will advise you on when it is safe to drive based on your recovery progress.

The timeline for returning to sport after knee arthroscopy depends on the specific condition treated and your individual recovery. Low-impact activities can often be resumed within a few weeks, while high-impact sports that involve running, jumping, or twisting may require a few months of recovery and rehabilitation. Dr Martin will assess your progress and provide personalised recommendations for safely returning to your preferred activities.
