Hip and Knee Scores

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.

Treatment and study plan

Primary outcomes

  1. Oxford Hip Score

    Time frame: The day Before surgery

    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.

  2. HOOS Score

    Time frame: The day Before surgery

    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.

  3. KOOS score

    Time frame: The day Before surgery

    Knee injury and Osteoarthritis Outcome Score (KOSS)

  4. Oxford knee score

    Time frame: The day Before surgery

    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.

Secondary outcomes

  1. Oxford Hip Score

    Time frame: an average between 6 to 9 months after surgery

  2. HOOS Score

    Time frame: an average between 6 to 9 months after surgery

  3. KOOS score

    Time frame: an average between 6 to 9 months after surgery

  4. Oxford knee Score

    Time frame: an average between 6 to 9 months after surgery
