Rethinking Osteoarthritis Management: Beyond Simple Wear and Tear

Osteoarthritis is not a simple consequence of joint aging or mechanical friction, but a complex disease requiring a comprehensive, multifaceted management strategy. This perspective was emphasized by Dr. Amanda E. Nelson during a presentation at the Congress of Clinical Rheumatology East on May 14, 2026.

Dr. Nelson, director of the Core Center for Clinical Research at the University of North Carolina at Chapel Hill, noted that osteoarthritis (OA) affects nearly 600 million people worldwide. Despite its prevalence, she stated that the medical community and patients often struggle with misconceptions regarding the nature of the condition.

A primary challenge in treating the condition is the persistent description of OA as simply wear and tear. Dr. Nelson suggested that this narrow framing can lead to a sense of defeatism among both patients and providers.

According to Dr. Nelson, Rheumatologists tend to be discouraged when thinking about osteoarthritis because the disease is often viewed as an inevitable result of aging that cannot be meaningfully altered.

Current medical research indicates that OA is a whole-joint disease rather than a localized loss of cartilage. It involves the interaction of multiple tissues, including the synovial membrane, subchondral bone, and surrounding ligaments and muscles.

Low-grade inflammation plays a significant role in the progression of the disease. While not as acute as the inflammation seen in rheumatoid arthritis, the inflammatory processes in OA contribute to pain and the degradation of joint structures.

The shift away from the wear-and-tear model allows for a more proactive approach to treatment. When OA is understood as a biological process involving inflammation and metabolic changes, the focus moves from passive acceptance to active management.

A multifaceted management strategy typically prioritizes non-pharmacological interventions as the first line of defense. These strategies are designed to reduce joint load and improve the functional capacity of the affected areas.

Weight management is a critical component of this approach, particularly for OA affecting the knees and hips. Reducing excess body weight decreases the mechanical stress on joints and lowers the systemic levels of pro-inflammatory cytokines released by adipose tissue.

Physical activity and tailored exercise programs are also essential. Rather than avoiding movement to prevent further wear, patients are encouraged to engage in low-impact activities that strengthen the muscles supporting the joints, which can alleviate pain and improve mobility.

Pharmacological treatments are generally used to manage symptoms and improve the quality of life. These may include topical or oral nonsteroidal anti-inflammatory drugs (NSAIDs), though their use is often balanced against potential risks to gastrointestinal and cardiovascular health.

Surgical interventions, such as joint replacement, remain an option for patients with severe joint destruction who do not respond to conservative management. However, the goal of a multifaceted strategy is to delay or avoid surgery by optimizing joint health through lifestyle and medical interventions.

The role of the rheumatologist in OA care is evolving toward a more integrated model. This involves coordinating care between physical therapists, nutritionists, and primary care providers to address the systemic and mechanical drivers of the disease.

By reframing OA as a manageable disease rather than an inevitable decline, clinicians can better motivate patients to adhere to long-term wellness strategies. This shift in perspective is necessary to address the global burden of the disease and improve long-term outcomes for millions of patients.
