NCT01207024

Brief Summary

Impact of loss of weight on knee arthrosis has not been thoroughly studied. The primary goal of this study is to compare the MRI parameters (aspect of cartilage and oedema of spongious sub-chondral bone) before and one year after bariatric surgery. Knee MRI is not currently part of the investigations preceding bariatric surgery.

Outcome Measures

Primary Outcomes (2)

  • variation of knee joint space thickness

    Joint space variation in percentages (mean joint space variation calculated for each patient group). Mean joint space comparison between 2 groups of obese patients: patients with Bypass surgery versus patients without surgery.

    24 hours, one year

  • proportion of patients with pain

    proportion of patients with Pain Scores on the Visual Analog Scale ≥ 30/100 (for at least one knee). Comparison at one year after bariatric surgery versus inclusion.

    1 year

Secondary Outcomes (6)

  • prevalence of atherosis

    24 hours

  • mean pain and disability

    24 hours

  • evolution of KOOS score after surgery

    6 months, 1 year and two years

  • evolution of pain scores after surgery

    6 months, 1 year, 2 years

  • evolution of the proportion of patients in pain

    6 months, 1 year and two years

  • +1 more secondary outcomes

Study Arms (1)

knee MRI

knee MRI for all patients undergoing bariatric surgery as usual care

Other: knee MRI

Interventions

knee MRI before surgery (inclusion) and one year after

knee MRI
