Osteoarthritis (OA) results from loss of cartilage in-tegrity in association with changes to the structure of the entire joint. Treatment of OA is based on different pharmaceutical and no phar-maceutical approaches and the latter include the use of spa-therapy. The biological effects of mud-bath therapy are mainly secondary to heat stimulation and to physic-chemical properties of mineral waters and mud-packs. Mud-bath therapy likely exerts its effects modulating several cytokines and other molecules involved in inflammation and cartilage degradation. Our aim was to perform an updated meta-analysis of the effectiveness of the mud-bath therapy on knee osteoarthritis and briefly to discuss the mechanisms of action of this treatment. A MEDLINE on PubMed for articles on knee OA and spa therapy published from 1995 through up to April 2019 was performed. Then, we checked the Cochrane Central Register of Controlled Trials to find additional references included up to April 2019. Articles were included if in accordance with the eligibility cri-teria. Sample size and effect sizes were processed with the MedCalc software package. Twenty one studies met the inclusion criteria and were included in meta-analysis. We examined WOMAC Index and VAS pain. We found significant improvements in function scores and painful symptoms after mud-bath therapy in patients with knee joint osteoarthritis. Spa therapy is a non-drug treatment modalities, non invasive, complication-free, and cost-effective alternative modality for the conservative treatment of knee osteoarthritis. It cannot substitute for conventional therapy but can integrated or alternated to it. Treatment with mud-bath therapy may relieve pain, stiffness and improve functio-nal status in patients with knee OA.
