Knee Arthroscopy

Overview

Knee arthroscopy is a minimally invasive surgery used to both diagnose and treat knee problems. Small incisions are made to insert a camera (arthroscope) and tiny instruments into the knee joint. The camera provides real-time images, allowing the surgeon to see inside of the joint and repair damaged cartilage, ligaments, and other tissues.

Knee arthroscopy may be recommended for patients with: 

  • Persistent knee pain that does not improve with rest, ice packs, non-steroidal anti-inflammatory drug (NSAID) therapy, and physical therapy.
  • Cartilage injuries (tear or damage)
  • Ligament injuries (such as ACL or meniscus tears).
  • Inflammation of the knee lining (synovitis)
  • Bursitis (inflammation of fluid-filled sacs)

  • Before the procedure, the knee is cleaned and secured.
  • A small incision is made, and the arthroscope is inserted.  
  • The surgeon views the inside of the knee on a monitor and uses specialised tools to repair of damaged tissues, remove inflamed or damaged material.
  • The incision is then closed with stitches or bandages.
     

Most knee arthroscopies take about 1 hour; patients usually go home the same day.

Preparation for the procedure may need the patient to:

  • Stop certain medications.
  • Fasting may be required for several hours before the procedure.
  • Anaesthesia options include local, regional, or general, depending on the case.

Knee arthroscopy is generally safe, but possible risks include:

  • Bleeding
  • Infection
  • Blood clots
  • Knee stiffness
  • Swelling

During the post-recovery phase:

  • Patients may need crutches for a short period after surgery.
  • Pain medication and keeping their knees elevated can help with recovery.
  • Physical therapy is important to regain strength and mobility.
  • Recovery times vary, so returning to sports or strenuous activity should be guided by the doctor to prevent re-injury.

Please contact your healthcare provider if you experience severe pain, bleeding, or signs of infection.
