Reporting Groups
  Description
2Gel-200 Patients already received 1 single dose of Gel-200 (3 mL) and followed up for 13 weeks in previous study(NCT00449696). After completion of previous study, patients entered this study and received 1 single dose of Gel-200 (3mL) intra-articular injection again into knee joint.
