We performed an arthroscopic TFCC reconstruction using a palmaris longus tendon graft that provided a minimally invasive procedure. After confirming the TFCC foveal tear and stability between the TFCC remnant and radius, the bone tunnel was made in the ulna from the ulnar shaft to ulnar fovea. The position of the bone tunnel was checked by fluorography and arthroscopy. Curved bendable 18-gauge needles into which 3-0 nylon sutures were inserted in a loop shape were passed through the tunnel from the ulnar side, and both volar-side and dorsal-side TFCC remnants were penetrated. The nylon suture was extracted from the arthroscopic 4/5 portal, and the palmaris longus tendon graft was introduced into the joint. The graft was passed through the TFCC remnant and ulnar bone tunnel from the arthroscopic portal and fixed to the ulna using an interference screw. This procedure was indicated for TFCC foveal tears with intact radial-side TFCC remnants. If the radial-side tear and instability between the TFCC and radius coexist, this technique is contraindicated, and stabilization of both the radial and ulnar sides of the TFCC should be considered. This arthroscopic technique does not violate the distal radioulnar joint capsule, extensor carpi ulnaris tendon, or tendon sheath. In addition, it helps to stabilize the ulnar carpal complex.
