Arthroscopic repair of radial‐sided triangular fibrocartilage complex tears

Treatment of triangular fibrocartilage complex (TFCC) tears is receiving considerable attention. Repair of peripheral tears of the TFCC has been recommended to restore the important functions of stability and load-bearing. Techniques for the reattachment of the periphery of the TFCC are evolving. Previous reports have mainly dealt with ulnar-sided (Palmer Class I-B) repairs. This report describes an arthroscopic technique for repair of radial-sided (Palmer Class I-D) TFCC tears. The procedure utilizes arthroscopic visualization with direct reattachment of the radial edge of the horizontal disk of the TFCC into the sigmoid notch of the distal radius. Fixation is achieved using sutures driven through the distal radius using long straight meniscal repair needles. Early clinical results following arthroscopic reattachment of radial-sided TFCC tears using this technique have been favorable. The technique is presented as an alternative method for repair of these lesions.
