Inclusion criteria: Subjects with PFP, aged 18 to 55. Agreement among 10 experts on the relevance and clarity of each item using Aiken's V coefficient determined content validity. An exploratory factorial analysis established structural validity. The correlation of VISA-P with knee injury and osteoarthritis outcome score for PFP and Osteoarthritis (KOOS-PF) and Kujala patellofemoral score (KPS; specific for PFP) analyzed the construct validity. Internal consistency was calculated with Cronbach's \u03b1  and test-retest reliability with the intraclass correlation coefficient (ICC). Feasibility considered the subjects' self-completion time.<\/jats:p>\n          <jats:p>RESULTS<\/jats:p>\n          <jats:p>The sample consisted of 103 knees from 73 subjects (47 female\/26 male; aged 34.9 \u00b1 13 SD). The items were relevant and clear, with the exception of item-8, which didn't reach an acceptable level of agreement on clarity. Exploratory factorial analysis found a 2-factor solution, which explained 63.48% of the variance. VISA-P achieved a strong and significant correlation with KOOS-PF (Spearman rho = 0.826; P  &lt; 0.001) and KPS (Spearman rho = 0.771; P  &lt; 0.001). The questionnaire showed adequate reliability (Cronbach's \u03b1 : 0.752; ICC: 0.934; P  &lt; 0.0001; 95%CI: 0.902-0.955). The mean self-completion time was 232 \u00b1 0.52 SD seconds.<\/jats:p>\n          <jats:p>CONCLUSION<\/jats:p>\n          <jats:p>VISA-P proved to be valid and reliable to functionally assess PFP and\/or chondromalacia patella. VISA-P is a feasible tool in the clinical and research environment, quick and easy to complete.<\/jats:p>","DOI":"10.5312\/wjo.v16.i6.105068","type":"journal-article","created":{"date-parts":[[2025,6,18]],"date-time":"2025-06-18T01:13:58Z","timestamp":1750209238000},"source":"Crossref","is-referenced-by-count":0,"title":["Validation of \u201cVictorian institute of sports assessment for patellar tendons\u201d in patellofemoral pain: Reliability, interpretability and feasibility study"],"prefix":"10.5312","volume":"16","author":[{"given":"Gema","family":"Chamorro-Moriana","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando","family":"Espuny-Ruiz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carmen","family":"Ridao-Fernandez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eleonora","family":"Magni","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2060","published-online":{"date-parts":[[2025,6,18]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1016\/s1440-2440(98)80005-4"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1016\/j.rehab.2021.101608"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1186\/s13104-021-05619-3"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-015-3521-z"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1007\/s12178-020-09646-8"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1016\/j.asmart.2015.07.001"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0190892"},{"key":"B8","unstructured":"Muaidi QI.
