Knee Arthroscopy

Alexander P. Sah

Knee arthroscopy refers to the use of a small camera to visualize the inner aspect of the knee joint. Inspection of the joint allows evaluation of the cartilage and soft tissues within the knee space. Technical advances have led to high-definition monitors and high-resolution cameras. Small instruments can be used to address cartilage tears, remove loose bodies, or remove problematic tissue. This procedure is performed on an outpatient basis, with a straightforward recovery. Knee arthroscopy is a commonly performed surgery, over 4 million yearly worldwide, and potential candidates should have a clear understanding of the nature of the operation, its advantages and disadvantages, and its limitations and contraindications.
