Abstract

Objective

To translate into Brazilian Portuguese and to cross-culturally adapt the Banff Questionnaire for Patellar Instability.

Methods

The translation and cross-cultural adaptation followed the linguistic validation process proposed by international guidelines, which consists of six steps: translation, synthesis, back-translation, review by an expert committee, pretest, and final report presentation to the authors of the original questionnaire. Literate patients with recurrent patellar instability, older than 12 years of age, who signed the informed consent form or had it signed by a legal guardian were included in the study. Patients with neurological or systemic comorbidities were excluded from the study.

Results

A total of 62 patients (18 males and 44 females) were included in the study. Discrepancies observed during the processes of translation and harmonization of the back-translations were modified with no need for reformulation. No pretest version replacements were required.

Conclusion

The Banff Questionnaire for Patellar Instability has been successfully translated and cross-culturally adapted into Brazilian Portuguese, so it can be used to assess patients with patellar instability who speak this language.

Question	Original Text (BPII)	Translation (VT12)	Changes for VBPF	Comment
1a	“…severity of the ’giving way’ episodes?”	“…episódios em que a rótula (patela) sai do lugar? (Gravidade)”	“…episódios em que a rótula sai do lugar? Qual a gravidade dos episódios de deslocamento?"	Expression with no idiomatic equivalent in Portuguese. To keep it understandable to the Brazilian population and preserve its conceptual equivalence, the term “dislocation” was avoided, using “kneecap out of place” (“rótula sai do lugar”) and “displacement” (“deslocamento”)
3	“…stiffness”	“joelho duro”	“joelho duro”	Although the committee believed that the most appropriate semantic equivalence would be “rigidez” (Portuguese for “stiffness”), the expression “joelho duro” (“hard knee”) had the same conceptual equivalence but greater understanding. So, it was kept in the VBPF
9	“…sudden twisting and pivoting movements or changes in direction”	“…movimentos de giro/rotação repentinos ou movimentos de mudanças de direção repentinos"	“…movimentos rotacionais ou de mudanças bruscas de direção”	Attempt to simplify the terms from translation VT12, maintaining its conceptual equivalence
14	“…knee ’giving way’"	“…joelho ’sair do lugar’"	“…rótula (patela) sair do lugar”	Expression with no idiomatic equivalence in Portuguese. “Joelho” (“knee”) from translation VT12 was replaced by “rótula (patela)” (“patella”) because, according to the committee, the translated term suggested the idea of the entire knee dislocating, instead of the patella alone
28	“…to psychologically ’come to grips’?”	“…superar psicologicamente”	“…superar psicologicamente”	Expression with no idiomatic equivalence in Portuguese, translated into an expression of similar conceptual equivalence, which was kept in the VBPF
