A Randomized Single-blinded Clinical Trial of the Efficacy of Intra-articular Infiltration of Cingal (Sodium Hyaluronate/Triamcinolone) Versus Cortisone (Triamcinolone) in Patients With Osteoarthritis of the Shoulder.
For patients suffering of osteoarthritis, only analgesic treatments such as anti-inflammatory drugs and cortisone infiltrations provide significant but temporary relief of their pain. The objective is to compare the analgesic effect of 2 infiltrations: Cingal (sodium hyaluronate and triamcinolone) versus cortisone (triamcinolone). It is anticipated that the Cingal infiltration will have a greater analgesic effect than a simple cortisone infiltration in patients with moderate to severe osteoarthritis of the shoulder. Method: * Randomized controlled trial * Monocentric * Randomization will be done using sealed envelopes
• A clinical examination that confirms the radiological diagnosis of moderate to severe primary shoulder osteoarthritis, stage II and above, according to the Samilson-Prieto classification.
• Patients aged between 20 and 90 years.
• A patient with bilateral shoulder osteoarthritis will choose the side of the infiltration, only one side can be chosen to participate in the study.
• The patient must have a clinical pain threshold of a minimum of 4/10 on the visual analogue scale.
• The patient must have the cognitive ability to read and fill out the questionnaires.
• The patient must be able to read and understand French or English
