Randomized Controlled TrialDeer Bone Extract Supplementation for Mild-to-Moderate Knee Osteoarthritis Symptoms: A Randomized, Double-Blind, Placebo-Controlled Trial.
In this randomized, double-blind, placebo-controlled study, we evaluated the efficacy of deer bone extract (DBE) in participants with knee osteoarthritis (OA). We enrolled 50 participants aged 50-70 years, having knee OA with a Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score ≥5.0. The participants were assigned to the placebo or DBE group (550 mg/day) for 12 weeks. ⋯ In the DBE group, VAS scores, WOMAC total scores, and WOMAC subscores (for pain, stiffness, and physical function) improved significantly compared with the baseline values. However, there was no significant difference in outcomes between the DBE and placebo groups. The present findings suggest that DBE may mildly reduce joint pain and stiffness and improve joint function in patients with painful knee OA.

Randomized Controlled TrialOral intake of a liquid high-molecular-weight hyaluronan associated with relief of chronic pain and reduced use of pain medication: results of a randomized, placebo-controlled double-blind pilot study.
The goal for this study was to evaluate the effects of daily oral intake of a consumable liquid fermentate containing high-molecular-weight hyaluronan, as well as to perform a basic evaluation of safety and tolerability. A randomized, double-blind placebo-controlled study design was used to examine the effects of oral intake of hyaluronan on chronic pain conditions. Safety assessment included a complete blood count with differential, blood chemistry and electrocardiogram. ⋯ During the last 2 weeks, a significant increase in the quality of sleep (P<.005) and level of physical energy (P<.05) was seen. The pain reduction during the initial 2 weeks was associated with significant reduction in the use of pain medication (P<.05). Consumption of an oral liquid formula containing high-molecular-weight hyaluronan was associated with relief of chronic pain.
