AIMS The aims of this study are: (1) to evaluate the long-term patient reported outcomes (PROM's) after revision CTR and compare these outcomes with patients who had a single CTR and a comparable age, sex, race, type of initial surgery and follow-up time, and (2) assess which factors are associated with worse PROM's after revision CTR. METHODS We retrospectively identified 7351 patients who had a single CTR and 113 patients who had a revision CTR for CTS between 01/2002 and 12/2015 at five academic urban hospitals. Of these 113 revision CTR cases, there were 37 patients who completed a follow-up questionnaire including the BCTQ, the NRS Pain and Satisfaction. Those who completed the follow-up questionnaire were randomly matched to five controls (patients who had a single CTR) based on age, sex, race, type of initial surgery, and follow-up time. Of these 185 matched controls, 65 patients completed the follow-up questionnaire. RESULTS A linear mixed effects model using the matched sets as a random effect showed that patients who had a revision CTR had a higher total BCTQ score, NRS pain score, and a lower satisfaction score at time of follow-up than patients who only had a single CTR. Multivariable linear regression showed that thenar muscle atrophy prior to the revision surgery was independently associated with more pain after revision surgery. CONCLUSION Patients improve after revision CTR, but generally have more pain, a higher BCTQ score, and are less satisfied at long-term follow-up compared to patient who had a single CTR.
