Arthroscopy is a surgical procedure orthopaedic surgeons use to visualize, diagnose, and treat problems inside a joint.

The word arthroscopy comes from two Greek words, "arthro" (joint) and "skopein" (to look). The term literally means "to look within the joint."

In an arthroscopic examination, an orthopaedic surgeon makes a small incision in the patient's skin unlike a large incision needed in conventional techniques, and then inserts pencil-sized instruments that contain a small lens and lighting system to magnify and illuminate the structures inside the joint. Light is transmitted through fiber optics to the end of the arthroscope that is inserted into the joint. The surgeon can then determine the amount or type of injury and then repair or correct the problem, if it is necessary.

Some of the most frequent conditions found during arthroscopic examinations of joints are:
1. Inflammation - For example, synovitis is an inflammation of the lining in the knee, shoulder, elbow, wrist, or ankle.

2. Acute or Chronic Injury -
  • Shoulder: Rotator cuff tendon tears, impingement syndrome, and recurrent dislocations
  • Knee: Meniscal (cartilage) tears, chondromalacia (wearing or injury of cartilage cushion), and anterior cruciate ligament tears with instability.
  • Wrist: Carpal tunnel syndrome.
  • Loose bodies of bone and/or cartilage: for example, knee, shoulder, elbow, ankle, or wrist.
3. Arthritis - Some problems associated with arthritis also can be treated. Several procedures may combine arthroscopic and standard surgery.
  • Rotator cuff surgery
  • Repair or resection of torn cartilage (meniscus) from knee or shoulder
  • Reconstruction of anterior cruciate ligament in knee.
  • Removal of inflamed lining (synovium) in knee, shoulder, elbow, wrist, ankle.
  • Release of carpal tunnel.
  • Repair of torn ligaments.
  • Removal of loose bone or cartilage in knee, shoulder, elbow, ankle, wrist.
Although the inside of nearly all joints can be viewed with an arthroscope, six joints are most frequently examined with this instrument. These include the knee, shoulder, elbow, ankle, hip, and wrist. As advances are made in fiberoptic technology and new techniques are developed by orthopaedic surgeons, other joints may be treated more frequently in the future.
