The Efficacy and Safety of Intraarticular Sodium Hyaluronate (Hyalgan) After Proximal Tibial Osteotomy in Treatment of Knee Osteoarthritis Patients

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01267214

Brief Summary:
The purpose of this study is to assess the efficacy and safety of Hyalgan after proximal tibial osteotomy in treatment of knee osteoarthritis patients. Normally, OA patients who were treated with osteotomy will not be treated with any SYSADOA after operation, even though their cartilage's not completely loss, so osteotomy plus HA injection should provide more benefit to patients than osteotomy alone.
