The following parameters were also evaluated in our study: validity, internal fit (Cronbach's a), reproducibility, ceiling/floor effect, filling rate, mean score, mean age of patients. Results. The study involved 200 patients hospitalized for primary knee arthroplasty. 167 of them (83%) were women, mean age 64.4 (SD 8.2) and 33 (17%) men, mean age 64 (SD 9.7). Validity index - 0.73, p
