          -  Disease of spine, hip or other lower extremity joints of sufficient degree to affect
             assessment of the index knee

          -  Untreated symptomatic injury of index knee (e.g., acute traumatic injury, anterior
             cruciate ligament injury, meniscus injury, cartilage lesion).

          -  Knee radiographs showing bone-on-bone or other gross cartilage deficits.

          -  Intra-articular steroid injections in the index knee within 3 months of screening.

          -  Intra-articular HA in the index knee within 6 months of screening.

          -  Other intra-articular therapy in the index knee within 6 months prior to screening.

          -  Systemic steroid use within 2 weeks of screening.

          -  Planned/anticipated surgery of the index knee during the study period.

             or psychiatric illness at screening which could compromise patient safety or interfere
             with the assessment of the safety and treatment effects of the study injection.

          -  Skin breakdown at the index knee where the injection is planned to take place.
