NCT01895959

Brief Summary

The purpose of this study is to identify novel imaging markers for characterizing the biochemical profiles in synovial fluid and cartilage matrix in OA knee joints after intra-articular HA (Euflexxa) injection using high field NMR and MRI techniques. We hypothesize that:

  1. 1.High-field HRMAS NMR spectroscopy will provide sensitive measures for biochemical changes within knee synovial fluid after HA injection;
  2. 2.Baseline HRMAS spectroscopy, in particular N-acetyl peaks, as well as early changes of glutamate will predict patient response of pain relief after HA injection;
  3. 3.MR cartilage T1p and T2 quantifications will provide sensitive measures for biochemical changes within knee cartilage matrix after HA injection. Specifically cartilage T1p and T2 will decrease in patients who respond to the treatment, indicating potential beneficial effects of HA injection to cartilage preservation.

Outcome Measures

Primary Outcomes (1)

  • To Identify Imaging Markers for Characterizing the Biochemical Profiles in Synovial Fluid and Cartilage in Knee OA After HA Injection

    The study will demonstrate the feasibility of using MRI and NMR techniques to quantify biochemical changes in synovial fluid and cartilage matrix in OA knees after HA injection.

    3 months

Secondary Outcomes (1)

  • To Quantify Synovial Fluid Biochemical Changes Using High Field HRMAS NMR Spectroscopy

    3 months

Other Outcomes (1)

  • To Quantify Cartilage Matrix Changes Using MR T1p ad T2 Mapping at 3T MRI

    3 months

Study Arms (1)

Euflexxa

OTHER

EUFLEXXA® is a hyaluronate hydrogel produced from bacteria, in a phosphate-buffered saline solution. It is given as a three week treatment regimen. It involves injecting of 2cc or 20mg intra-articularly once per week.

Drug: EuflexxaDevice: Magnetic Resonance Imaging (MRI)

Interventions

Euflexxa will be injected weekly for 3 consecutive weeks on the knee joint.

Also known as: hyaluronic acid injection
Euflexxa

MRI of the knee will be acquired during baseline (a week prior to the treatment), follow up visit 1 (1 week after treatment) and follow up visit 2 (3 months after treatment).
