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.
1PBS1Gel-200 Patients already received 1 single dose of Phosphate Buffered Saline (PBS) placebo (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 into knee joint.
