Study summary

In a pilot study, the investigators recently showed that intraarticular metallic gold microparticles reduce knee osteoarthritis pain for up to two years and found associated significant proteomic changes in serum and synovial fluid within eight weeks. This study aim to evaluate the outcome after intra-articular injection of gold microparticles for hip osteoarthritis.

Read the detailed description

A cohort of 20 patients, aged ≥ 18 years, with pain ≥ 3 months, and Kellgren-Lawrence OA grade 2-4, will beincluded. Metallic gold 20 mg, 72.000 pieces, 20-40 µ-meter (Berlock-Micro-Implants, HumanGoldInject) (1) were injected into the hip joint using hyaluronic acid as the carrier. In total, we treated 24 hip joints. The primary outcome was the Western Ontario and McMaster Universities Arthritis Index (WOMAC).

What researchers measure

Primary outcomes

  1. WOMAC

    Western Ontario and McMaster Universities Arthritis Index, sub-scores for pain, stiffness, and function, containing 24 questions: 5 pain questions, two stiffness questions, and 17 physical function questions.

    Time frame: 2 year

Secondary outcomes

  1. PainDetect

    The secondary outcome measure PainDetect questionnaire (PDQ) comprises three major components, gradation of pain, pain course pattern, and radiating pain. Seven questions evaluate the gradation of pain. The patient scored each question using a 0 to 5 score with 0 = never, 1 = hardly noticed, 2 = slightly, 3 = moderately, 4 = strongly and 5 = very strongly. There is one question evaluating pain course patterns. Patients select from one of four pictures indicating which pattern best describes their course of pain. Each picture has a unique score of 0, -1, or +1 (2 pictures have this score possible). One question evaluates radiating pain with a yes (score of +2) or no (score of 0) response option. PDQ is scored from 0 to 38, with total scores \< 13 considered to represent nociceptive pain, 13-18 possible neuropathic pain, and \> 18 representing neuropathic pain.

    Time frame: 2 year
