Knee arthroscopy — sometimes called knee scoping — is a minimally invasive medical procedure used on the knee joint to diagnose and treat knee conditions or injuries. It’s performed using an arthroscope, which is a tiny surgical instrument with a light and camera at the end that is inserted into the knee.

A doctor may recommend knee scoping if a patient has a painful condition that is not responding to a nonsurgical treatment such as medication, cortisone injection or physical therapy.  In particular, knee arthroscopy is often successful in helping reduce or eliminate pain associated with cartilage damage or soft tissue damage.

Many doctors and patients prefer knee scoping to other procedures. That’s because the orthopedic knee surgeon only needs to make a tiny incision to use the arthroscope. There is usually less knee pain, less joint stiffness and easier recovery than with other procedures.

When Knee Arthroscopy Is Performed

Knee arthroscopy can be used when making or confirming a diagnosis and performing surgery:

• Making a Diagnosis: If a patient has knee pain, a doctor may order an X-ray or other imaging tests. However, the provider might need more information before moving forward with a treatment like surgery. In this instance, the doctor can use knee scoping for a diagnosis or to confirm treatment. To do this, a doctor makes a single small incision, then inserts the tiny arthroscope into the knee, and the images can be viewed on a video screen. An example of how this might be used is when a surgeon wants to view a meniscus tear to assess the extent of the damage.
• Performing Surgery: If arthroscopy is being used for surgery, small incisions are made at different points around the knee joint, in addition to the opening that’s made for the arthroscope. These additional openings allow the doctor to insert tiny surgical tools into the area as needed. Using the images from the arthroscope as a guide, the surgeon can repair torn ligaments, remove a torn or damaged meniscus, remove loose bone fragments or perform other treatments.

Unless a patient has another medical issue, knee arthroscopy may performed in an outpatient setting, so the patient will not need to stay overnight at a hospital.

Knee surgery using an arthroscope can take 30 minutes to several hours, depending on the extent of the damage. When using knee arthroscopy for diagnosis only, the time could be even shorter.

Before knee arthroscopy, a patient will have some type of anesthesia. The doctor and patient will determine whether local (numbing knee only), regional (numbing from waist down) or general anesthesia (putting patient to sleep) is best.

After Knee Surgery

After the procedure, the surgeon will close the incision. Sometimes, only small strips of adhesive tape are needed. Other times, one or two small stitches will be required.

Next, the patient rests in a recovery room for several hours. At home, the patient will follow the doctor’s instructions, which may include taking certain medications, elevating the knee, getting plenty of rest and eventually, exercising. Usually, a patient can return to light activity within a few weeks, although every patient is different.

Many people think arthritis is a single, chronic disease. Actually, arthritis refers to more than one hundred different conditions, some of which are acute and temporary while others are chronic. Various types of arthritis cause symptoms such as stiff, swollen or achy joints. Other arthritic conditions have wide-ranging symptoms and causes.

Understanding the types of arthritis and common symptoms allows patients to get treatment sooner, and therefore, avoid worse pain and further joint damage. In some cases, patients can avoid surgery if arthritis is diagnosed early.

Here are some common types of arthritis and symptoms:

• Ankylosing spondylitis: A chronic condition that affects joints near the center of the body, often the spine and sacroiliac joints (found at the base of the spine). People often experience back pain and stiffness, as well as buttock pain.
• Bursitis: Bursitis occurs when the fluid-filled sacs in the joints (bursae) become inflamed, achy or stiff. Bursitis most commonly occurs in the elbow, shoulder, hip and knee, and often, the area becomes swollen, red and tender.
• Carpal tunnel syndrome: A repetitive stress injury that causes tingling and numbness in the thumb, first finger and middle finger. Patients may experience hand weakness or shooting pain.
• DeQuervain’s tendinitis: A condition that causes pain on the side of the wrist and the base of the thumb.
• Dupuytren’s contracture: This form of arthritis causes the tissue beneath the hand to develop nodules in the fingers and palms. These lumps can cause the fingers to stick in place.
• Gout: Gout typically attacks one joint at a time, often the joint of the big toe. Gout usually causes sudden, severe pain and swelling.
• Infectious arthritis (septic arthritis): If an infection gets into the bloodstream, it can cause the tissues and fluid in the joints to become infected as well. Infectious arthritis causes the joints to appear red and feel warm and may also result in fever and chills.
• Juvenile idiopathic arthritis: This is a term used to describe several conditions that affect children younger than 16. Juvenile idiopathic arthritis can cause joint pain, stiffness, swelling, skin rashes and eye pain.
• Lupus arthritis (systemic lupus erythematous): A condition in which the immune system attacks the tissues of the body. Symptoms can be mild to severe and can include joint stiffness and a butterfly-shaped rash on the face.
• Osteoarthritis: One of the most common forms of arthritis, osteoarthritis results from a breakdown in cartilage. This causes bone to rub against bone, resulting in pain, stiffness and decreased range of motion in the joint.
• Osteoporosis: This condition causes the bones to become fragile. Common symptoms include a decrease in height, a stooped over appearance and back pain.
• Polymyalgia rheumatica: This form of arthritis happens only in the shoulder, causing stiffness and achiness.
• Rheumatoid arthritis: This is a condition in which the immune system attacks the body’s tissues in error. Rheumatoid arthritis causes pain, swelling and stiffness in the joints.
• Spinal stenosis: This is an abnormal narrowing of the spinal canal. When this happens, it can compress the nerves and spinal cord which can cause numbness, tingling and weakness.
• Traumatic arthritis: Traumatic arthritis develops after an injury or physical trauma. Swelling and joint pain are common.
