Surgery requires resilience when recovering from pain, time off work, and therapy. Grit is defined as “perseverance and passion for long-term goals.� It is not known whether patient grit is associated with patient reported outcomes in hand surgery. The aim of this study was to examine the correlation between grit and self-reported upper extremity physical function among patients undergoing basal thumb arthroplasty.


A retrospective chart review from 2020-2022 was completed for patients who underwent basal thumb arthroplasty. Patients completed the 8-question GRIT Scale, a validated measure of passion and perseverance for long-term goals measured on a scale of 0 (least grit) to 5 (most grit). QuickDASH scores were completed before surgery and after surgery at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year. QuickDASH scores were compared with one-way ANOVA. Correlations between GRIT Scale and QuickDASH scores at each time point and changes in QuickDASH scores were calculated using Pearson correlation coefficients. Data was reported as mean ± SD and significance was set at p<0.05.


Nineteen patients (16F:3M) were included (60 ± 7.7 years). Mean GRIT score was 3.9 ± 0.5. QuickDASH score was 48 ± 15 pre-surgery (n=19) and 29 ± 16 at 1 year post-surgery (n=11) (p=0.0529). There was no statistically significant correlation between GRIT and QuickDASH scores or GRIT and change in QuickDASH scores at any time point. There was a trend towards significance for correlation between GRIT score and QuickDASH at 6 weeks (p=0.0532) as well as GRIT score and change in QuickDASH from pre-surgery to 1 year post-surgery (p=0.0578).


In patients undergoing basal thumb arthroplasty, no statistically significant correlation between GRIT and functional recovery as measured with QuickDASH scores was noted in this small pilot study. A prospective study with larger sample size is underway.
