Arthroscopic Removal of Tenosynovial Giant-Cell Tumors of the Cruciate Ligaments. Presentation of Two Cases.

Background: Tenosynovial giant-cell tumor (GCT) arising from cruciate ligaments consists a rather rare entity. Predominantly areas where this tumor appears are the palmar sides of fingers and toes. The involvement of larger joints such as the knee or the ankle is rather rare, but, in the case of synovial joints, the knee joint is particularly affected.
