Abstract
An arthroscopic partial resection of triangular fibrocartilage complex (TFCC) was performed on 8 patients with TFCC lesion. All cases had a history of trauma. Arthroscopy revealed that 7 patients had traumatic TFCC lesion and only one had a degenerative TFCC lesion. Clinical results of the procedures were evaluated using Kido's criteria. Results were excellent for 7 of the cases, in which the TFCC lesions seemed to be traumatic in origin. Results for the remaining case were poor, indicating a degenerative TFCC lesion (class 2B) associated with fibrillation of the ulnar side of the lunate. Outcomes were good for traumatic TFCC lesions (class 1A) treated using arthroscopic partial resection; however, degenerative TFCC lesions may require ulnar-shortening osteotomy or use of Wafer's procedure when positive results cannot be obtained using arthroscopic partial resection.
