Keywords:
Gel development, Osteoarthritis, Herbal gel, Traditional Thai MedicineAbstract
Knee osteoarthritis is a significant problem in the elderly population. Although Kamala poultice is effective, it has limitations in terms of convenience of use. To develop Kamala gel and compare its efficacy with Kamala poultice for reducing knee pain and disease severity in osteoarthritis patients and evaluate patient satisfaction. Randomized controlled trial with parallel group design. Participants: 54 patients with primary knee osteoarthritis divided into experimental group (Kamala gel) and control group (Kamala poultice), 27 patients each, randomized using block randomization. Instruments: Visual Analog Scale (VAS), Oxford Knee Score (OKS), and patient satisfaction questionnaire with Cronbach's α = 0.85-0.92.
Results: Kamala gel showed appropriate physical properties with pH 5.2 and 30-day stability. Superior pain reduction compared to control group (3.65 vs 0.35 points, p<0.001), better OKS improvement (12.65 vs 0.80 points, p<0.001), and high patient satisfaction (95%). Kamala gel demonstrated superior efficacy compared to Kamala poultice, with convenience of use and high patient satisfaction. Implementation in healthcare systems and long-term efficacy studies are recommended.
