ICF rehabilitation set responsiveness after total knee arthroplasty: a retrospective study

ICF-RS demonstrates responsiveness to post-TKA inpatient rehabilitation for most functional domains. The lack of change in b710 highlights a limitation of generic assessment tools for capturing localized physical impairments in single-joint conditions, suggesting the need for complementary condition-specific measures. The study context-where ICF-RS scores influence reimbursement-underscores the importance of assessment integrity considerations in function-based payment implementations.
