Frequently Asked Questions About Osteoarthritis

1. What exactly is osteoarthritis, and why does it develop?

Osteoarthritis is the most common degenerative joint disease. It doesn’t just affect cartilage—it involves the entire joint structure, including the bone, synovial lining, ligaments, and surrounding soft tissues. It was once thought to be nothing more than “wear and tear” due to aging, but we now understand that it’s a complex, chronic, and inflammatory condition influenced by multiple factors: age, body weight, lifestyle, joint injuries, and genetics.

The knees and hips are most commonly affected, but osteoarthritis can also impact the hands and feet.

2. How is osteoarthritis diagnosed? Do I need special tests?

In most cases, osteoarthritis can be diagnosed through a detailed clinical interview and physical examination—without the need for routine X-rays or MRI unless there are unusual features (such as sudden worsening, recent injury, or suspicion of another condition).

Key signs include:

• Joint pain that worsens with movement and improves with rest

• Minimal or short-lived morning stiffness

• Age over 45

Imaging is not always helpful—some people have severe X-ray changes with few symptoms, while others experience significant pain with minimal visible damage.

3. What can I do on my own to improve my condition?

The most effective strategy is regular physical activity. Exercises should be tailored to your needs and may include:

• Strengthening exercises for muscles around the affected joints

• Aerobic activities like walking, swimming, or biking

• Stretching and mobility work to maintain flexibility

Don't get discouraged if you feel some discomfort at first—it often improves with time.

Losing weight is the second key factor. Even a 5–10% reduction in body weight can significantly ease joint pain and improve function. Balanced eating and a healthy lifestyle make a big difference in managing symptoms and staying active.

4. When are medications used for osteoarthritis?

Medications are not the foundation of treatment, but they can help relieve pain in the short term—mainly to make it easier to stay active.

First-line treatments include:

• Topical NSAIDs (gels or creams), especially effective for knees, hands, and other surface joints

• Oral NSAIDs (like ibuprofen or naproxen) should be used cautiously and only as needed due to potential risks to the stomach, heart, and kidneys. A stomach-protecting medication is often recommended.

Not recommended:

• Acetaminophen (Tylenol), glucosamine, hyaluronic acid injections, and dietary supplements—due to lack of proven benefit

• Strong opioids—reserved only for short-term use in rare cases when other treatments fail or are contraindicated

5. Should I try alternative treatments like acupuncture, electrotherapy, or supplements?

The scientific evidence shows that acupuncture, electrotherapy (including TENS, ultrasound, and laser), hyaluronic acid injections, and most dietary supplements are not effective for the majority of patients with osteoarthritis. That’s why leading experts do not recommend them routinely.

Instead, the core of effective treatment remains:

• Movement

• Weight management

• Personalized support and education

If you're considering an alternative therapy, it's important to discuss the potential risks and benefits with your healthcare provider first.

Introduction

Arthritis refers to a diverse group of inflammatory joint diseases that are a leading cause of chronic pain, disability, and reduced quality of life among adults worldwide. The two most common forms—osteoarthritis (OA) and rheumatoid arthritis (RA)—differ significantly in cause, progression, and clinical presentation, yet both carry substantial social and economic burdens.

Over the past decade, our understanding of osteoarthritis has evolved dramatically. Once seen simply as the result of “wear and tear” on cartilage, OA is now recognized as a complex, chronic disease that affects the entire joint and involves intricate biochemical and cellular processes. Rheumatoid arthritis, on the other hand, is a systemic autoimmune disorder where early diagnosis and timely use of disease-modifying therapies are crucial in preventing irreversible joint damage.

Epidemiological studies reveal alarmingly high rates of both conditions—particularly among women and older adults—highlighting the need for integrated, personalized strategies for treatment and prevention. Modern clinical guidelines emphasize the importance of physical activity, early intervention, and shared decision-making between patients and healthcare providers.

Current research is focused on the molecular mechanisms driving the development of arthritis and on creating innovative treatment strategies that combine conservative, pharmacological, and integrative approaches. All of this underscores arthritis as an interdisciplinary challenge of central importance to both rheumatology and public health.

Understanding Osteoarthritis

Osteoarthritis is the most prevalent degenerative joint disease and a leading cause of chronic pain, disability, and diminished quality of life in middle-aged and older adults. While it was long thought to result simply from cartilage wearing down with age, medical science now recognizes OA as a multifaceted condition that affects every component of the joint—including cartilage, bone, synovium, ligaments, and surrounding structures. OA most commonly affects the knees and hips but can also involve the small joints of the hands and feet, leading to multifocal symptoms and significant functional limitations.

Epidemiological data show a consistent rise in osteoarthritis cases, closely linked to an aging population, rising obesity rates, and social factors that limit physical activity. In the UK alone, over 8.5 million people are affected by OA, with similar numbers reported across other developed countries. This trend presents significant challenges to healthcare systems—not only in terms of treatment but also in prevention, early diagnosis, and comprehensive patient support.

In recent years, both clinical guidelines and rheumatology research have called for a shift in how osteoarthritis is understood and managed. Rather than viewing it as a purely structural issue, OA is now recognized as a progressive, inflammatory condition with key metabolic and immunological components. Diagnosis relies heavily on clinical evaluation, while imaging is mainly used to rule out other conditions. Today, non-pharmacologic interventions—especially regular physical activity and weight management—form the cornerstone of treatment, with medications used primarily to manage symptoms and improve function.

This overview summarizes the latest evidence-based recommendations and expert consensus on the diagnosis and treatment of OA. Special attention is given to approaches that empower patients to take an active role in their care through education, shared decision-making, and access to personalized support. Clarifying the role of both non-drug and pharmacological therapies, as well as when surgical referral is appropriate, is critical to improving patient outcomes and satisfaction.

Understanding the complex nature of osteoarthritis, recognizing individual variations in how the disease progresses, and integrating the best available evidence into daily practice are all key to reducing the societal and economic impact of this condition. This review aims not only to present current guidelines and ongoing debates but also to spark broader discussion about the future of OA prevention and care in the face of an aging population and rising expectations for healthcare delivery.

When to Suspect Osteoarthritis

Diagnosing osteoarthritis relies primarily on a thorough clinical history and physical exam, with routine imaging such as X-rays or CT scans generally unnecessary. Current guidelines emphasize that OA should be diagnosed based on typical symptoms and the absence of red flags suggesting other conditions. The key signs that point to osteoarthritis include:

• Age over 45 – OA is most commonly seen in middle-aged and older adults, though it can occur earlier in individuals with risk factors such as previous joint injury or obesity.

• Joint pain related to activity – The pain typically worsens with joint use, such as walking or climbing stairs, and improves with rest. Many patients report that discomfort increases toward the end of the day, following extended activity.

• Lack of morning stiffness or stiffness lasting less than 30 minutes – Unlike other inflammatory joint diseases, OA is characterized by minimal or absent morning stiffness. If present, stiffness usually resolves quickly once the joint is in motion.

The Role of Imaging in Osteoarthritis

Imaging techniques such as X-rays or magnetic resonance imaging (MRI) are generally not required to confirm a diagnosis of osteoarthritis in typical cases and often do not add clinically meaningful information. These tools are reserved for situations where atypical or concerning symptoms are present, such as:

• Sudden or rapidly worsening joint symptoms

• A recent history of trauma

• Obvious joint deformity

• Signs suggesting inflammation or infection (e.g., swelling, redness, warmth, fever)

• Suspicion of other underlying conditions, including possible tumors

In such cases, imaging can be helpful in ruling out other conditions or complications. However, it is not considered a first-line diagnostic tool for classic presentations of osteoarthritis.

Why Is the Clinical Approach Preferred?

Relying on a clinical approach not only reduces unnecessary healthcare costs and avoids radiation exposure, but it also saves time and helps minimize patient anxiety. Additionally, imaging findings do not always correlate with symptom severity—some individuals may show advanced changes on imaging with little or no pain, while others with minimal radiographic findings may experience significant discomfort.

For this reason, modern clinical guidelines recommend that physicians base the diagnosis of osteoarthritis primarily on the patient’s symptoms, physical exam findings, and overall clinical context. The emphasis is on understanding the patient's individual experience and functional limitations, rather than relying solely on imaging results.

What Patients Need to Know About Osteoarthritis

Osteoarthritis Is Not “Just Wear and Tear”

The old idea that osteoarthritis is merely “mechanical wear and tear” on the joints is now outdated and misleading. Today, science recognizes osteoarthritis as a chronic, progressive condition that affects all parts of the joint—not just the cartilage, but also the underlying bone, synovial lining, ligaments, and surrounding soft tissues. The disease involves complex biochemical and cellular changes that lead to pain, stiffness, and gradual loss of mobility.

That’s why treatment must go beyond simply relieving symptoms—it should focus on maintaining and improving joint function over the long term.

Movement Is Medicine

Physical activity is the most effective “treatment” for osteoarthritis. Regular exercise has been shown to reduce pain, improve joint mobility, and slow the progression of the disease.

Exercise plans should be personalized and may include strengthening exercises targeting the muscles around the affected joint, low-impact aerobic activities like walking, swimming, or cycling, and flexibility exercises to maintain range of motion.

It’s normal to experience some increased discomfort at the start of an exercise program, but this typically subsides as your body adjusts. The most important factor is consistency. Research shows that long-term physical activity not only eases pain but also boosts overall physical and mental well-being.

Many patients benefit from guided or group exercise programs, which can help with motivation and provide professional support.

“Therapeutic exercise is essential for people with osteoarthritis—it reduces pain and improves function and quality of life.” — George Wood, NICE Guideline Committee

Weight Management Matters

Excess weight is a major factor that worsens osteoarthritis symptoms and accelerates joint damage—especially in weight-bearing joints like the knees and hips. Even a modest reduction in body weight can lead to noticeable improvements in pain, mobility, and quality of life.

The greatest benefits are seen with a 10% reduction in body weight, but any amount of weight loss can help. Shedding pounds not only reduces the mechanical stress on joints but also lowers systemic inflammation levels.

Patients should be encouraged to adopt balanced eating habits and stay physically active. Structured weight loss programs and guidance from a registered dietitian can be helpful for those who need extra support.

Medication Is a Tool—Not the Foundation of Treatment

While many people rely on medication to manage pain, current clinical guidelines emphasize that pharmacologic treatment should play a supportive—not central—role. The primary focus should remain on non-drug strategies like exercise and weight control.

That said, medications can still be useful in certain cases:

• Topical NSAIDs (nonsteroidal anti-inflammatory drugs) in the form of gels or creams are the first-line option for pain relief in accessible joints such as the knees and hands. They are generally safer and have fewer side effects.

• Oral NSAIDs (tablets) may be used cautiously and only for short periods due to the risk of gastrointestinal, cardiovascular, and kidney-related side effects. When prescribed, they are typically paired with protective medications for the stomach.

• Strong opioids are not recommended except in rare, extreme cases where all other treatments are ineffective or contraindicated. They carry a high risk of dependence and serious side effects.

• Acetaminophen (Tylenol), glucosamine, hyaluronic acid, and various dietary supplements are not routinely recommended, as current evidence does not support their effectiveness.

A Personalized, Supportive Approach

Every person with osteoarthritis is different—with unique needs, lifestyles, and health circumstances. That’s why treatment must be individualized and tailored to the patient’s personal goals and preferences. Key components include:

• Education – Patients should receive clear, accessible information about their condition, treatment options, and what to expect in the future.

• Shared decision-making – The best outcomes are achieved when patients and healthcare providers work together to choose the right plan of care.

• Support – Peer support groups, online resources, educational programs, and multidisciplinary care teams can make living with osteoarthritis more manageable and help keep patients motivated.

Practical Recommendations for Patients with Osteoarthritis

Stay Physically Active

Extensive research and expert clinical guidelines agree: regular physical activity is the most effective non-drug strategy for managing osteoarthritis symptoms and slowing disease progression. Therapeutic exercise—whether it's strength training, aerobic activity, or flexibility exercises—leads to meaningful reductions in pain, improved joint function, and better quality of life.

NICE expert recommendation: "Therapeutic exercise is essential for people with osteoarthritis—it reduces pain and improves function and quality of life." — George Wood, NICE Guideline Committee

Experts recommend that exercise programs be tailored to each individual’s needs and, whenever possible, guided by a qualified professional—especially at the beginning or when other health conditions are present. Even short but consistent daily movement can make a noticeable difference. Regular activity helps preserve joint function and supports long-term independence.

Manage Your Weight

Multiple studies have confirmed that weight loss significantly reduces pain and improves mobility in people with osteoarthritis, especially when the knees or hips are affected. Even a modest 5% weight reduction can help, but the greatest benefits are typically seen with a 10% loss of initial body weight.

Physically, losing weight reduces mechanical stress on the joints and lowers systemic inflammation—both key factors in disease progression.

NICE (2023) guidance: “Any weight loss is beneficial, but losing 10% of body weight brings a significant improvement in quality of life and physical function.”

A combination of balanced nutrition and increased physical activity is ideal. For added support, patients can seek help from a registered dietitian or participate in structured weight loss programs.

Use Medications Only When Needed

As previously mentioned, medications should be considered a supporting tool—not the foundation—of osteoarthritis treatment. Non-drug strategies like exercise and weight management remain the primary approach.

When medications are needed, here’s what experts recommend:

• Topical NSAIDs (nonsteroidal anti-inflammatory drugs, such as creams or gels) are a first-line option. They are effective for joints close to the surface (e.g., knees, hands) and have fewer side effects than oral medications.

• Oral NSAIDs should be used only when topicals aren’t sufficient and must be carefully monitored due to risks of gastrointestinal, cardiovascular, and kidney complications. Stomach-protective medications are often recommended alongside them.

• Strong opioids are not recommended, except as a last resort for short-term use in severe cases when other treatments have failed or are contraindicated.

NICE Committee statement: “Pharmacological therapy should not be used long-term and must be administered at the lowest effective dose for the shortest possible time.”

Discuss All Treatments with Your Healthcare Provider

Despite widespread use, treatments such as acupuncture, electrotherapy (TENS, ultrasound, laser), hyaluronic acid injections, glucosamine, and various dietary supplements are not recommended based on current evidence. Studies have not demonstrated reliable benefits.

If a treatment is being offered or suggested to you, talk with your healthcare provider to weigh the potential risks and benefits before starting.

Age, Gender, and Weight Should Not Be Barriers to Care

Modern clinical guidelines clearly state that no one should be denied treatment or surgery based on age, gender, weight, or other health conditions. In fact, evidence shows that people with higher body weight can still achieve excellent outcomes with appropriate therapy and surgical interventions.

Every patient deserves a personalized evaluation and access to the care that best meets their needs.

Empowerment Through Knowledge and Partnership

The latest research and expert consensus are clear: an active, informed approach and a strong partnership with your healthcare team are key to managing osteoarthritis effectively. The goal is not just to control symptoms, but to enhance your overall quality of life—through regular movement, healthy weight management, appropriate medication use, and personalized support.

What Remains Unclear or Controversial in Osteoarthritis Care?

Non-Pharmacological Interventions with Mixed Evidence

Many patients explore alternative therapies to manage osteoarthritis symptoms, but scientific support for some non-pharmacological interventions remains limited—or even contradictory.

Electrotherapy techniques—including TENS (transcutaneous electrical nerve stimulation), ultrasound, laser therapy, and interferential therapy—have not shown consistent or statistically significant benefits in clinical trials. Experts from NICE and other leading rheumatology organizations emphasize that "there is insufficient evidence to support the routine use of electrotherapy for osteoarthritis," with any potential benefits being modest or temporary at best.

Acupuncture and dry needling are also not routinely recommended. Systematic reviews and meta-analyses have failed to demonstrate meaningful pain relief or functional improvement when compared to placebo.

Dietary supplements such as glucosamine and chondroitin have been widely studied, but results are inconclusive. Experts agree that "there is not enough reliable evidence to support their routine use in patients with osteoarthritis."

Hyaluronic Acid Injections – An Ongoing Debate

Hyaluronic acid (HA) injections are often marketed as an “innovative” treatment for joint pain, but expert reviews caution that their benefits may not exceed those of placebo.

Large meta-analyses have found little to no clinically meaningful improvements in pain or joint function compared to placebo or other standard treatments. Organizations like NICE do not recommend HA injections as part of routine care, citing insufficient benefit, along with potential downsides such as local reactions, cost, and inconvenience for patients.

Which Exercises Work Best – and How Should Patients Be Monitored?

While physical activity is universally endorsed as the foundation of osteoarthritis care, there is ongoing debate about which types of exercise are most effective for different groups of patients.

Both strength training and aerobic exercises are supported by evidence, but there’s no consensus on the “ideal” combination or format. Some studies suggest added value from supervised group programs, but such options are not always accessible or appropriate for every individual.

Another area of discussion is the optimal follow-up model: should patients self-manage their activity, or attend regular appointments with a specialist? NICE notes that "more data is needed to assess the clinical and cost-effectiveness of different follow-up strategies—whether self-directed or professionally guided."

Personalized Care and the Need for Further Research

Experts unanimously support an individualized approach to osteoarthritis care, but also emphasize the need for additional research. Specifically, future studies should identify which treatment strategies work best based on a patient’s age, lifestyle, comorbidities, and personal preferences.

While there is strong consensus around the core treatment pillars—physical activity and weight management—many supplementary or alternative therapies remain controversial. Patients are encouraged to work closely with their healthcare providers and prioritize strategies backed by strong scientific evidence and clinical experience.

In Summary

Osteoarthritis is one of the most common chronic conditions affecting the musculoskeletal system, with serious implications for daily function, mobility, and psychosocial well-being. Despite its progressive nature, modern medicine offers a clear and actionable framework for managing the disease and slowing its progression.

Today’s clinical guidelines—rooted in extensive research and expert consensus—emphasize the importance of early and accurate diagnosis, which avoids unnecessary imaging and streamlines care.

At the heart of osteoarthritis management are non-pharmacological interventions such as regular physical activity and weight control. These approaches not only reduce pain but also preserve joint function, slow disease progression, and help patients remain independent and active. Medications serve as a supportive tool, primarily to ease symptoms and enable participation in physical therapy and daily activities.

A modern treatment plan also includes an individualized and collaborative approach: empowering patients with accessible information, involving them in shared decision-making, and encouraging the use of social and emotional support networks. This holistic strategy leads to better symptom control, improved quality of life, and a stronger sense of agency in managing one’s health.

Ultimately, the goal is to help individuals with osteoarthritis maintain maximum functional independence at every stage of life. With timely diagnosis, consistent physical activity, a balanced diet, and judicious use of medication, each patient has the opportunity to live fully and delay the negative effects of the disease.

With this modern, balanced approach, osteoarthritis becomes a manageable challenge—not an inevitable fate—offering real opportunities for active participation, informed choice, and a longer life with greater quality.

Conclusion

Arthritis encompasses a large and diverse group of joint disorders affecting millions of people worldwide. It is one of the leading causes of chronic pain, limited mobility, and reduced quality of life. The two most common forms—osteoarthritis (OA) and rheumatoid arthritis (RA)—differ significantly in their causes, underlying mechanisms, and progression. Yet both require a comprehensive, personalized, and informed approach to treatment and daily care.

Osteoarthritis typically develops slowly, often as a result of aging, excess weight, or prolonged joint overuse. It primarily affects cartilage and the underlying bone and is associated with mechanical wear-and-tear, metabolic changes, and a possible genetic predisposition. Symptoms tend to appear gradually: joint pain that worsens with movement, brief morning stiffness, cracking or grinding sounds in the joints, and limited range of motion. Diagnosis is usually made through physical examination and X-rays; lab tests are rarely necessary. Treatment focuses on non-drug strategies such as weight management, regular physical activity, rehabilitation, and patient education. Medications—primarily nonsteroidal anti-inflammatory drugs (NSAIDs)—are used to relieve pain in the short term. In more advanced cases, joint injections or surgery may be considered. Ongoing research into regenerative medicine, stem cells, and novel biomaterials offers hope for transformative approaches in the future.

Rheumatoid arthritis, on the other hand, is an autoimmune disease in which the immune system mistakenly attacks the body's own joint tissues. This leads to chronic inflammation, swelling, pain, and eventual joint deformity. Symptoms often come on suddenly and typically affect small joints in the hands and feet symmetrically. Prolonged morning stiffness and persistent fatigue are also common. RA has complex causes, involving a mix of genetic predisposition, environmental triggers (like smoking), and certain infections. Specific autoantibodies—such as RF and ACPA—play a key role in diagnosis and disease prediction. Accurate diagnosis requires a combination of clinical evaluation, lab testing, and imaging, with an emphasis on early detection.

Early treatment is essential—there is a narrow “window of opportunity” in the first few months where intervention can significantly limit long-term damage. The foundation of RA therapy is disease-modifying antirheumatic drugs (DMARDs), especially methotrexate. If results are inadequate, biologic agents or targeted synthetic drugs (like JAK inhibitors) may be added. A "treat-to-target" approach involves regularly adjusting treatment until remission or low disease activity is achieved. Exercise, patient education, rehabilitation, and supportive therapies play key roles alongside medication.

What unites the modern approach to all forms of arthritis?

First and foremost, treatment must be personalized—tailored to each patient’s age, lifestyle, comorbidities, and preferences. Leading experts and medical guidelines emphasize that early, multidisciplinary intervention (involving physicians, physical therapists, psychologists, and social workers) leads to better outcomes and helps prevent disability.

Second, regular disease monitoring, shared decision-making between patients and providers, and the integration of digital tools for tracking and customizing treatment are now essential parts of arthritis care.

Today, medical science aims not only to relieve symptoms, but to alter the course of the disease itself—to slow or stop its progression, preserve joint structure, and improve overall quality of life. Thanks to early diagnosis, innovative treatments, and the merging of medical and social support systems, the outlook for people with arthritis is more hopeful than ever before. At the same time, numerous scientific studies are paving the way for even safer and more effective therapies in the near future.

In summary: Arthritis is not a single condition, but a complex spectrum of diseases requiring a modern, individualized, and evidence-based approach. The expert consensus today is clear: with the right treatment, early diagnosis, active patient participation, and the application of cutting-edge science and technology, it is entirely possible to gain control over the disease, preserve mobility, and live a full and active life.
