We selected patients who were aged at least 18 years and underwent arthroscopic repair of peripheral ulnar\u2010side TFCC tears. We excluded those with a fractured or dislocated wrist, ulnar impaction syndrome, degenerative or inflammatory arthritis of the wrist, or neurologic conditions that affect upper\u2010extremity function, as well as those who received less than 12 months\u2019 follow\u2010up. We evaluated the patients with a visual analog scale for pain in 3 domains (overall, with hard work, and at rest), the Patient\u2010rated Wrist Evaluation, range of motion, and grip strength. Clinical outcomes and arthroscopic findings were compared between patients with and without UPV (UPV group and non\u2010UPV group, respectively). We calculated the relative risk and 95% confidence interval for younger age (&lt;30 years), sex, UPV, and coexisting degenerative central TFCC tear (type 2 tear) to determine the risk factors for arthroscopic repair failure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      No significant differences were noted between the 2 groups regarding visual analog scale pain and Patient\u2010rated Wrist Evaluation scores and rates of excellent or improved outcomes (\n                      <jats:italic>P<\/jats:italic>\n                      &gt; .05).
