Osteoarthritis (OA) impacts millions, especially older adults and women. New, effective treatments are needed for OA patients with other chronic conditions, as current options are only moderately effective.
Area of Science:
- Gerontology
- Rheumatology
- Public Health
Background:
- Osteoarthritis (OA) is a prevalent degenerative joint disease, affecting over 33% of individuals aged 65 and older, with a higher incidence in women.
- Risk factors such as obesity, sedentary lifestyles, and joint injuries are contributing to a rising prevalence of OA.
- OA significantly impacts quality of life, causing pain, functional limitations, sleep disturbances, fatigue, and reduced independence, leading to increased healthcare costs and lost productivity.
Purpose of the Study:
- To highlight the growing burden of osteoarthritis (OA) and the challenges in managing patients with co-existing chronic conditions.
- To emphasize the need for more effective and safer treatment strategies for individuals with OA and comorbidities.
Main Methods:
- Literature review and synthesis of epidemiological data on OA prevalence and risk factors.
- Analysis of the impact of OA on patient quality of life and economic burden.
- Examination of treatment efficacy and safety in patients with OA and other chronic conditions, particularly cardiometabolic diseases.
Main Results:
- OA affects a substantial portion of the elderly population, with increasing prevalence linked to modifiable risk factors.
- OA patients experience significant functional limitations and economic costs, with a high comorbidity rate, especially cardiometabolic conditions.
- Current treatments, including exercise and self-management, offer only moderate effectiveness for symptomatic OA, particularly in patients with other chronic illnesses.
Conclusions:
- The rising prevalence and multifaceted impact of OA necessitate urgent development of improved therapeutic interventions.
- There is a critical need for enhanced research to identify more effective and safer treatments for the large population of OA patients managing other chronic health issues.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
