All-arthroscopic knotless suture anchor repair of triangular fibrocartilage complex fovea tear by the 2-portal technique.

After the importance of the deep fiber of the distal radioulnar ligament had been acknowledged, some repair techniques have been introduced. Because the knotless suture anchor does not cause any knot irritation and yields appropriate tension, it is a useful fixation material. All-arthroscopic knotless suture anchor repair of the triangular fibrocartilage complex fovea tear by a 2-portal technique is easier and less vulnerable to ulnar nerve injury than the original Geissler technique. Instead of the suture hook and accessory portal, this technique uses the always-sharp 18-gauge needle and percutaneous route. This change results in the repair of the complex fovea tear having the smallest possible remnant tissue. Repair of triangular fibrocartilage complex fovea tears combined type IB, ID, and IIC tears can reduce the chance of needing to perform distal radioulnar ligament reconstruction.
