Hip and Knee Scores

Study of Self-assessment Questionnaires Used in Hip and Knee Surgery

Patient-reported outcome measures (PROMs) are currently used for evaluating orthopaedic procedures. Nevertheless, there is no consensus in the different studies, making them difficult to compare . The score mapping (or cross walk) is a statistical model for estimating a score associated with an unmeasured score.

Moreover , Minimal clinically important differences (MCID) is the smallest change in a treatment outcome that a patient would identify as important. The MCID is also not clearly identified for the French population for the hip and knee orthopaedic scores.
