Patellofemoral pain is a common and often debilitating musculoskeletal condition. Clinical translation and evidence synthesis of patellofemoral pain research are compromised by heterogenous and often inadequately reported study details. This consensus statement and associated checklist provides standards for REPORTing of quantitative PatelloFemoral Pain (REPORT-PFP) research to enhance clinical translation and evidence synthesis, and support clinician engagement with research and data collection. A three-stage Delphi process was initiated at the 2015 International Patellofemoral Research Network (iPFRN) retreat. An initial e-Delphi activity (n=24) generated topics and items, which were refined at the 2017 iPFRN retreat, and voted on prior to and following the 2019 iPFRN retreat (n=51 current and past retreat participants). Voting criteria included ‘strongly recommended’ (essential), ‘recommended’ (encouraged) and uncertain/unsure. An item was included in the checklist if ≥70% respondents voted ‘recommended’. Items receiving ≥70% votes for ‘strongly recommended’ were labelled as such. The final REPORT-PFP checklist includes 31 items (11 strongly recommended, 20 recommended), covering (i) demographics (n=2,4); (ii) baseline symptoms and previous treatments (n=3,7); (iii) outcome measures (2,4); (iv) outcomes measure description (n=1,2); (v) clinical trial methodology (0,3) and (vi) reporting study results (n=3,0). The REPORT-PFP checklist is ready to be used by researchers and clinicians. Strong stakeholder engagement from clinical academics during development means consistent application by the international patellofemoral pain research community is likely. Checklist adherence will improve research accessibility for clinicians and enhance future evidence synthesis.

  • Contributors Initial research design was carried out by DM, CJB and SM following the 2015 retreat led by MJC and JS. Initial survey content was guided by DM, CJB, SM, MJC, MvM, KMC, MSR and BV. SM, CJB and DM analysed stage 1 findings to inform subsequent stages. NJC and BV facilitated the 2017 retreat. Stage 2 small group discussions were led by CJB, DDOS, NJC, MSR, BV, MVM, KMC, MJC, JS, SH, SL, EMM, CMP and ISD. CJB, MVM, KMC, MSR, BV, NJC and DM developed the final consensus voting surveys. DB-J and JEE-B facilitated the 2019 retreat and voting on potential checklist items. CJB coordinated final consensus discussions. CJB and DDOS led synthesis of results following consensus voting surveys. All authors contributed to read and approved the final manuscript.
