NCT03665116

Brief Summary

This study evaluates the effects arginine on osteoarthritis (OA) in adults. Participants will be randomly divided into two groups, taking arginine and nothing, respectively. Outcomes will be evaluated by lab test results on OA joint cartilage and self-administered questionnaires. The hypothesis is that arginine can slow down or reverse OA.

Outcome Measures

Primary Outcomes (1)

  • Target Gene Expressions in Osteoarthritic Knee Cartilage after 6 Months of Supplementation

    After participants have been taking arginine or nothing for 6 months, and cartilage tissue has been obtained during participants' total knee replacement surgery, target gene expressions in cartilage are measured with quantitative polymerase chain reaction (qPCR). Genes include cartilage degradation enzymes - matrix metallopeptidase 13 (MMP13), cathepsin K (CTSK), cathepsin B (CTSB), and cartilage syntheses genes - aggrecan (ACAN) and type II collagen (CTXII).

    up to 20 months

Secondary Outcomes (7)

  • OA Severity Grade of Osteoarthritic Knee Cartilage after 6 Months of Supplementation

    up to 6 months

  • WOMAC to Measure Changes in Joint Pain and Function between baseline and at 6 Months

    at baseline and in 6 months

  • WOMAC to Measure Changes in Joint Pain and Function between baseline and at 6 Months Post-surgery

    at baseline and 6 months post-surgery

  • WOMAC to Measure Changes in Joint Pain and Function between baseline and at 12 Months Post-surgery

    at baseline and 12 months post-surgery

  • SF-36 to Measure Changes in Physical and Mental Function between baseline and at 6 Months

    at baseline and in 6 months

  • +2 more secondary outcomes
