Arthritis is often spoken about as if it were a single condition, but it is actually an umbrella term covering more than 100 disorders that affect joints and connective tissues. Among them, osteoarthritis (OA) and rheumatoid arthritis (RA) are the two most common—and the most misunderstood.
Both conditions lead to joint pain, stiffness, and reduced mobility. However, their causes, progression, and treatments differ dramatically. Today, advances in regenerative medicine are shedding new light on acellular therapies, which focus on repairing tissues and modulating inflammation without the use of living cells. These innovations offer promising, safer alternatives for people with chronic joint disease.
