Brief Summary

Total knee arthroplasty remains the gold standard in the management of disabling gonarthrosis. Improved functional results, increased availability of care and an ageing population have all contributed to the rise in total knee replacement surgery in Western countries. Surgical techniques have been steadily improving for several decades in terms of implant positioning and joint alignment. However, 10% of patients are dissatisfied with the clinical and functional results. The challenge is to understand why these patients remain dissatisfied despite these surgical advances. Our aim is to understand the functional impact of knee prosthesis through a quantified analysis of gait, the performance of certain tasks of daily living, and pre- and post-operative proprioceptive assessments. We will link these results with patient feedback to identify factors potentially responsible for poor postoperative outcomes.

Outcome Measures

Primary Outcomes (1)

  • Post-operative functional recovery of patients who have undergone total knee arthroplasty for gonarthrosis by analyzing their locomotion ability

    The primary endpoint is a composite endpoint assessed by quantified gait analysis (QGA) : 1/ Gait speed 2 / Step length

    Preoperatively (PreOP) and 12 months postoperatively (PostOP12)

Secondary Outcomes (9)

  • Functional recovery by analyzing changes in gait variability

    Preoperatively (PreOP) , 3 months postoperatively (PostOP3), 12 months postoperatively (PostOP3)

  • Impact of total knee arthroplasty (TKA) on proprioception

    Preoperatively (PreOP) , 3 months postoperatively (PostOP3), 12 months postoperatively (PostOP3)

  • Functional recovery after TKA by analyzing changes in daily living tasks by SIT TO STAND test

    Preoperatively (PreOP) , 3 months postoperatively (PostOP3), 12 months postoperatively (PostOP3)

  • Functional recovery after TKA by analyzing changes in daily living tasks by STEP INITIATION test

    Preoperatively (PreOP) , 3 months postoperatively (PostOP3), 12 months postoperatively (PostOP3)

  • Functional recovery after TKA by analyzing changes in daily living tasks by OBSTACLE CLEARANCE test

    Preoperatively (PreOP) , 3 months postoperatively (PostOP3), 12 months postoperatively (PostOP3)

  • +4 more secondary outcomes

Interventions

The following explorations will be carried out pre-operatively (pre-OP), then post-operatively at 3 months (post-OP3) and 12 months (post-OP12) : * Quantified gait analysis (QGA) * Functional tests (mechanical analysis of everyday tasks): * SIT-TO-STAND test (test consisting of standing up and sitting down on a chair) * STEP INITIATION test (test consisting of walking up a step and then down) * Proprioceptive tests : * Joint Position Sense (JPS) (angle memorization and reproduction test at the knee joint) * OBSTACLE CLEARANCE test (test consisting in simulating the clearance of an obstacle) * Questionnaires : * Functional questionnaires : * KSS (Knee Society Score) * SKV (Simple knee value) * KOOS (Knee Injury and Osteoarthritis Outcome Score) * Quality of life (EQ5D-5L) The total duration of each exploration session is estimated at 1 hour .
