PG - 516-516.e7 LID - S0363-5023(20)30675-4 [pii] LID - 10.1016/j.jhsa.2020.11.007 [doi] AB - PURPOSE: To calculate the minimal clinically important difference (MCID) of the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Test (UE CAT) and Quick-Disabilities of the Arm, Shoulder, and Hand (QuickDASH) for ligament reconstruction tendon interposition (LRTI) patients. METHODS: Adult patients treated with LRTI for trapeziometacarpal OA by fellowship-trained hand surgeons between December 2014 and February 2018 at an academic tertiary institution were included. Outcomes were prospectively collected at each visit by tablet computer, including the QuickDASH, PROMIS UE, Pain Interference, Depression, and Anxiety CATs. Inclusion required a response to the anchor question "How much relief and/or improvement do you feel you have experienced as a result of your treatment?" on a 6-option Likert scale, as well as preoperative (
