“…Subgroup analysis was performed based on treatment groups with ceiling effects for the Sports subscale among nonoperative patients (22%) and ceiling effects for the ADL (21%) and Sports (54%) subscales among operative patients. 26 These ceiling effects are similar to the results presented in the present study.…”

“… 5 , 16 , 20 The Foot and Ankle Ability Measure (FAAM) is used to evaluate a myriad of lower extremity disorders, and it has also been shown to have substantial content relevance to patients with Achilles tendon disorders. 19 , 26 The more recently developed Patient-Reported Outcomes Measurement Information System (PROMIS) provides a comprehensive set of questionnaires, and critically, items can be administered as a computerized adaptive test (CAT) to limit the number of questions that a patient must answer to attain a score. The PROMIS Physical Function (PROMIS PF) CAT has been shown to be an excellent method for measuring outcomes for patients with foot and ankle injuries.…”

Background: There is increased demand for valid, reliable, and responsive patient-reported outcome measures (PROMs) to evaluate treatment for Achilles tendon rupture, but not all PROMs currently in use are reliable and responsive for this condition. Purpose: To evaluate the measurement properties of the Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS PF) compared with other PROMs used after treatment for acute Achilles tendon rupture. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A retrospective cohort study with a follow-up questionnaire was performed. All adult patients with an acute Achilles tendon rupture between June 2016 and June 2018 with a minimum 12-month follow-up were eligible for inclusion. Functional outcome was assessed using the PROMIS PF computerized adaptive test (CAT), Foot and Ankle Ability Measure (FAAM) Activities of Daily Living (ADL), FAAM–Sports, and Achilles Tendon Total Rupture Score (ATRS). Pearson correlation ( r) was used to assess the correlations between PROMs. Absolute and relative floor and ceiling effects were calculated. Results: In total, 103 patients were included (mean age, 44.7 years; 74% male); 82 patients (79.6%) underwent operative repair, while 21 patients (20.4%) underwent nonoperative management. The mean time between treatment and collection of PROMs was 25.3 months (range, 15-36 months). The mean scores were 55.4 ± 9.2 (PROMIS PF), 92.9 ± 12.2 (FAAM-ADL), 77.7 ± 22.9 (FAAM–Sports), and 83.0 ± 19.4 (ATRS). The ATRS was correlated with FAAM-ADL ( r = 0.80; 95% CI, 0.72-0.86; P < .001) and FAAM–Sports ( r = 0.86; 95% CI, 0.80-0.90; P < .001). The PROMIS PF was correlated with the FAAM-ADL ( r = 0.66; 95% CI, 0.53-0.75; P < .001), FAAM–Sports ( r = 0.65; 95% CI, 0.53-0.75; P < .001), and ATRS ( r = 0.69; 95% CI, 0.58-0.78; P < .001). The PROMIS PF did not show absolute floor or ceiling effects (0%). The FAAM-ADL (35.9%), FAAM–Sports (15.8%), and ATRS (20.4%) had substantial absolute ceiling effects. Conclusion: The PROMIS PF, FAAM-ADL, and FAAM–Sports all showed a moderate to high mutual correlation with the ATRS. Only the PROMIS PF avoided substantial floor and ceiling effects. The results suggest that the PROMIS PF CAT is a valid, reliable, and perhaps the most responsive tool to evaluate patient outcomes after treatment for an Achilles tendon rupture.
