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 ]

Secondary Outcome Measures:
  • Changes of cartilage volume and subchondral bone lesions [ Time Frame: One year ]
  • Pain measured by VAS [ Time Frame: One year ]
  • WOMAC index [ Time Frame: One year ]
  • SF-36 Health Questionaire [ Time Frame: One year ]
  • Assessment of joint swelling, effusion [ Time Frame: One year ]
  • Use of rescue medication [ Time Frame: One year ]
  • Tolerability [ Time Frame: One year ]
  • Adverse events [ Time Frame: One year ]

Estimated Enrollment: 70
Study Start Date: February 2008
Primary Completion Date: November 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Chondroitin sulphate
Drug: Chondroitin sulphate (Condrosan)
800 mg (two capsules of 400 mg each) taken once a day for one year
Placebo Comparator: 2 Drug: Placebo
Two placebo capsules taken once a day for six months followed by an additional six month treatment of 800 mg (two capsules of 400 mg of Chondroitin sulphate each) taken once a day


Ages Eligible for Study:   40 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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.
