Study summary

Viscosupplementation has been widely used for the treatment of knee osteoarthritis (OA). There is no well controlled trial comparing one injection regimen of HA for the treatment of knee OA. The purpose of this study was to compare the efficacy and safety of one intraarticular injection of a novel crosslinked HA (HYAJOINT Plus) with Synvisc-One for the treatment of knee OA.

Read the detailed description

In a prospective, randomized controlled, double-blind trial with 6-month follow up, patients with knee OA (Kellgren-Lawrence grade 2 or 3) were randomized to receive one intraarticular injection of 3 ml HYAJOINT Plus (microbial fermented HA, 20 mg/ml) (N=66) or 6 ml Synvisc-One (avian derived HA, 8 mg/ml) (N=66). The primary outcome was change in the visual analog scale (VAS) pain (0-100mm) over 6 months. Secondary outcomes included The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lequesne index, Timed Up-and-Go test (TUG), single leg stance test (SLS), use of rescue analgesics and patient satisfaction.

What researchers measure

Primary outcomes

  1. VAS pain score

    the change from baseline in the VAS pain score over 6 months.

    Time frame: at 1, 3 and 6 months postinjection

Secondary outcomes

  1. WOMAC, Likert Scale

    a 24-item questionnaire with 3 subscales measuring pain, stiffness, and physical function. Total score is 96 and lower scores indicate better outcomes.

    Time frame: at 1, 3 and 6 months postinjection

  2. Lequesne index

    Maximal score is 24 and higher scores represent worse function.

    Time frame: at 1, 3 and 6 months postinjection

  3. Timed Up-and-Go test (TUG)

    a simple measurement of time in seconds for a person to rise from an armchair, walk 3 meters, turn around, walk back to the chair, and sit down

    Time frame: at 1, 3 and 6 months postinjection

  4. Single-leg stance test (SLS)

    by raising one foot up without touching it to the supported lower extremity with target knee OA and maintain balance for as long as possible.

    Time frame: at 1, 3 and 6 months postinjection

  5. satisfaction based on a 100 mm VAS

    Patients were asked to rate their treatment satisfaction compared to the preinjection condition, based on a 100 mm VAS

    Time frame: at 1, 3 and 6 months postinjection

  6. The reported adverse events

    based on adverse events reported by the patients during the study period and physical examination findings by the evaluator after injections and at each follow-up visit

    Time frame: at 1 week (safety records via phone call), 1, 3 and 6 months after the injection
