The American Orthopedic Foot and Ankle Society hallux metatarsophalangeal-interphalangeal joint scale (AOFAS Hallux MTP-IP) is originally developed in English to evaluate joint function in patients with elbow stiffness. The purpose of this study is to translate and cross-culturally adapt the AOFAS Hallux MTP-IP scale into Turkish and investigate its psychometric properties. Approximately seventy patients with hallux deformities will be included. For cross-cultural adaptation, two bi-lingual translators will use the back-translation procedure. Within a 5-to-7-day period after the first assessment, the participants will complete the Turkish version of AOFAS Hallux MTP-IP (AOFAS Hallux MTP-IP-T) to evaluate test-retest reliability. Cronbach's alpha (α) will use to assess internal consistency. The correlation with the Turkish version of the Manchester-Oxford Foot Questionnaire (MOXFQ) and Short Form-12 will be determined to check the validity.
