Hip and Knee Scores

Study Overview
=================
Brief Summary
-----------------
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Oxford Hip Score | t is a 12-item patient-reported outcome measure designed to assess disability after surgery to the hip. Each item was scored between 0 and 4, with 4 been the best outcome per question producing overall scores running from 0 to 48(48 being the best outcome); > 41 is excellent, 34 - 41 is good,27 -33 as fair, and <27 is poor. | The day Before surgery | 
| HOOS Score | The HOOS (Hip disability and Osteoarthritis Outcome Score) is a patient questionnaire evaluating patients' feelings about their operated hip. It consists of 40 questions divided into 5 subgroups: pain, symptoms, daily living, quality of life, sports and recreational activities. Each category is scored on 100 points, 0 being the worse outcome and 100 the best outcome. | The day Before surgery | 
| KOOS score | Knee injury and Osteoarthritis Outcome Score (KOSS) | The day Before surgery | 
| Oxford knee score | Oxford Knee Score is a tool which measures 6 post operative items (pain,flexion contracture, extension lag, total range of flexion, alignment of varus and valgus,stability (antero-posterior and mediolateral). The scoring is: below 60 is poor, scoring 60-69 fair, scoring 70-79 good, 80-100 excellent. | The day Before surgery | 

Secondary Outcome Measures
