Primary Outcome Measures:
  • Number of participants with an acute inflammatory reaction in the injected knee [ Time Frame: up to 7 days ]
    An acute inflammatory reaction in more than 5% of the participants will be considered as manifestation of treatment related intolerance

  • Change from baseline in blood count [ Time Frame: 3 days and 7 days ]
  • Number of participants with adverse events [ Time Frame: Up to 90 days after the treatment ]

Secondary Outcome Measures:
  • Maximum global pain in the target knee [ Time Frame: Days -21, 0, 1, 3, 7, 14, 30, 90th ]
    Measured by Visual Analogue Scale for pain (VAS)

  • The Western Ontario and McMaster University OA index (WOMAC) [ Time Frame: Days 0, 7, 14, 30, 90 ]
  • The patient global assessment of treatment by Likert-scale questionnaire [ Time Frame: Days 0, 7, 14, 30, 90 ]
  • The patients acceptance of symptoms state (PASS) [ Time Frame: Days 7, 14, 30, 90 ]
  • Omeract-ORASI responders index [ Time Frame: Days 7, 14, 30 ]
  • The number of tablets of rescue medications used between visits [ Time Frame: During the study ]

Arms Assigned Interventions
Experimental: MM-II Device: MM-II
Single intraarticular (knee) injection of MM-II
Active Comparator: DurolaneTM
hyaluronic acid
Device: DurolaneTM
Single intraarticular (knee) injection of DurolaneTM
Other Name: hyaluronic acid

Detailed Description:
Osteoarthritis (OA) is the commonest form of joint disease, characterized by articular cartilage degradation with an accompanying periarticular bone response and a synovial membrane inflammation. Clinical manifestations of OA in the knee include pain in and around the joint, stiffness of the joint after rest, crepitus on motion and limited joint. MM-II medical device was designed to reduce wear and lower friction in knees of osteoarthritis patients by creating a lubricating layer onto cartilage surfaces upon injection. The purpose of this study is to determine whether a medical device MM-II is effective in the treatment of osteoarthritis, in direct comparison with an approved hyaluronic acid preparation.
