Primary Outcome Measures:
  • Evaluation of the change in the severity of synovitis measured by MRI according to the modified methods of Loeuille et al. after chondroitin sulphate treatment in patients with knee OA and clinical signs of synovitis [ Time Frame: One year ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Changes of cartilage volume and subchondral bone lesions [ Time Frame: One year ] [ Designated as safety issue: No ]
  • Pain measured by VAS [ Time Frame: One year ] [ Designated as safety issue: No ]
  • WOMAC index [ Time Frame: One year ] [ Designated as safety issue: No ]
  • SF-36 Health Questionaire [ Time Frame: One year ] [ Designated as safety issue: No ]
  • Assessment of joint swelling, effusion [ Time Frame: One year ] [ Designated as safety issue: No ]
  • Use of rescue medication [ Time Frame: One year ] [ Designated as safety issue: No ]
  • Tolerability [ Time Frame: One year ] [ Designated as safety issue: Yes ]
  • Adverse events [ Time Frame: One year ] [ Designated as safety issue: Yes ]

  Eligibility

Ages Eligible for Study:   40 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Primary OA of the knee according to ACR with synovitis criteria (warmth, swelling or effusion);
  • OA of radiological stages 2 and 3 according to Kellgren-Lawrence;
  • Minimum joint space width ≥2 mm in the medial femorotibial compartment on standing knee X-ray;
  • VAS of pain while walking ≥40 mm.

Exclusion Criteria:

  • Known allergy to chondroitin sulphate;
  • Progressive or serious pathologies (cancer, AIDS,...);
  • Other bone and articular diseases (antecedents and/or current signs) such as chondrocalcinosis, Paget's disease, rheumatoid arthritis, aseptic osteonecrosis, gout, septic arthritis, ochronosis, acromegaly, hemochromatosis, Wilson's disease, osteochondromatosis;
  • Corticosteroids (oral, injectable), indomethacin, therapeutic dose of glucosamine or chondroitin sulphate during the 12 weeks preceding inclusion;
  • Hyaluronic Acid (intra-articular pathway) during the 26 weeks preceding inclusion;
  • Radioactive synovectomy during the 12 weeks preceding inclusion;
  • If the patient is receiving NSAID at baseline (D0), it should be maintained at a stable dosage as much as possible from D0 to D180. In the open phase of the study (D180 to D360), NSAID will also be allowed as rescue medication along with acetaminophen.
