Ligament Reconstruction Tendon Interposition, or better known as LRTI, has been the traditional surgical treatment of Basal Joint Arthritis since the 1970s. The diseased trapezium bone is removed, and then typically the flexor carpi radialis tendon is cut. A bone tunnel is drilled in the first metacarpal, and the free end of the tendon is passed through the tunnel, and finally fixated either to itself, or using a small anchor. There are many different modifications to this core technique that include utilizing a different tendon, using an allograft, and fixation preference.
