The year 2019 witnessed an astounding count of 528 million individuals with osteoarthritis globally. This underscores the pressing requirement for thoroughly understanding the condition and designing an efficacious integrated pain treatment plan.
That being said, this blog will explore what osteoarthritis is, its causes, risk factors and how it progresses over time. The latter half of the blog offers treatment options examining both traditional surgical approaches and the ever-evolving landscape of non-surgical alternatives.
Comprehensive understanding of Osteoarthritis
What is Osteoarthritis?
Osteoarthritis(OA) is a degenerative joint disease that primarily affects the cartilage – the protective cushioning between the bones in a joint. Cartilage is a smooth, rubbery tissue that covers the ends of bones in joints, allowing them to glide smoothly against each other during movement. In individuals with OA, this cartilage gradually breaks down and becomes less effective in cushioning and protecting the bones. As a result, joint functionality is impaired, leading to pain, stiffness, and reduced range of motion.
While Osteoarthritis can affect any joint in the body, it most commonly targets the knees, hip joint, hands, and spine. This condition doesn’t discriminate; it can impact people of all backgrounds, races, age, and genders. However, statistics reveal a significant trend: approximately 73% of osteoarthritis patients are older than 55 years, and interestingly, around 65% of these patients are female. These figures underscore the substantial impact osteoarthritis has on the ageing population, particularly women.
Difference between Osteoarthritis and other types of Arthritis
It’s important to differentiate between OA and other types of arthritis, such as rheumatoid arthritis (RA). While both conditions affect your joints, they have distinct underlying mechanisms and characteristics. OA primarily involves the wear and tear of cartilage due to ageing, repetitive joint stress, or joint injury, resulting in gradual joint degradation.
On the other hand, RA is an autoimmune disorder where the body’s immune system attacks the synovial membrane, a lining that surrounds the joints. This leads to inflammation, pain, and potential joint deformities. Unlike RA, OA is not an autoimmune condition and doesn’t involve the same level of systemic inflammation.
Typical joints affected and stages of the disease
OA can affect various joints in the body, but it most commonly targets weight-bearing joints and those subject to repetitive use. The knees, hips, hands, and spine are frequently affected areas. Statistics reveal that 19%to 30% of adults over the age of 45 have knee osteoarthritis.
The disease progresses through several stages:
- Early stage: In the early stages of OA, the cartilage begins to show signs of thinning and damage. This might lead to occasional discomfort or stiffness after physical activity. However, joint pain isn’t usually severe at this point.
- Moderate stage: As OA progresses, the cartilage continues to deteriorate, causing increased friction between bones. This results in more noticeable pain, stiffness, and reduced flexibility in the affected joint. Inflammation might also occur in the surrounding tissues.
- Advanced stage: In the advanced stage, the cartilage loss is substantial, causing bones to come into direct contact with each other. This can lead to significant pain, a limited range of motion, joint deformities, and potential bone spurs. Daily activities become increasingly difficult.
- Severe stage: At this stage, the joint’s structural integrity is severely compromised. Pain can be intense, even at rest, and joint function is significantly impaired. Joint deformities might become pronounced, leading to altered biomechanics and affecting the overall quality of life.
Why does it happen?
To delve into the medical intricacies of osteoarthritis while keeping it comprehensible, let’s break down the key aspects: risk factors, underlying mechanics, and the role of inflammation.
Risk factors
Age: As we age, our bodies naturally undergo changes. One such change involves the cartilage becoming less efficient at repairing itself, making it more susceptible to wear and tear.
Gender: OA tends to affect women more often than men, especially after menopause. Hormonal changes could play a role, but the exact mechanism is still being studied.
Genetics: Genetic factors can influence the integrity of cartilage and the efficiency of joint maintenance processes. If you have a family history of OA, you might be at higher risk.
Obesity: Carrying excess weight places extra stress on weight-bearing joints like the knees and hips. This increased stress can accelerate the breakdown of cartilage over time.
Underlying mechanics
The underlying mechanics of osteoarthritis involve a complex interplay of biochemical, biomechanical, and genetic factors. In a healthy joint, cartilage maintains its structural integrity through a balance between the synthesis and degradation of its components, primarily collagen and proteoglycans. However, in osteoarthritis, this balance is disrupted. Chronic mechanical stress, genetic predisposition, and age-related changes can lead to a breakdown in cartilage structure.
The disease begins with microstructural changes within the cartilage, including disruption of collagen fibres and loss of proteoglycans, which contribute to decreased cartilage resilience and shock-absorbing capacity. This leads to increased friction and stress on the underlying bone. In response, the bone attempts to remodel itself, forming osteophytes (bone spurs) and alterations in joint shape.
Inflammation in the joint lining (synovium) and the release of enzymes further contribute to cartilage degradation. As the disease progresses, the joint’s lubricating fluid may lose its effectiveness, exacerbating friction and pain.
Traditional treatments of Osteoarthritis
Traditional treatments for osteoarthritis mainly aim to manage symptoms such as pain, stiffness, and reduced mobility and improve the overall quality of life. Let’s delve into some of these treatments:
Medication:
Common pain relievers: Medications like acetaminophen help manage pain by blocking pain signals, but they don’t address the cause of osteoarthritis.
Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): NSAIDs like ibuprofen and naproxen relieve pain and inflammation by blocking enzymes that produce inflammatory chemicals. Long-term use might lead to side effects like stomach irritation or kidney issues.
Corticosteroids: These powerful anti-inflammatory medications can be injected directly into affected joints to reduce pain and swelling. However, excessive or prolonged use can result in side effects like tissue or bone weakening.
Physical Therapy
One key component of managing osteoarthritis is physical therapy, which involves exercises and routines designed to alleviate symptoms and improve joint function. An essential aspect of these exercises is the emphasis on strengthening the muscles surrounding the affected joint.
Understanding the role of muscles
In osteoarthritis, the cartilage that cushions the ends of bones within a joint gradually wears away, leading to bone-on-bone friction that causes inflammation and pain. Muscles play a critical role in supporting joint structure and function. They act like natural shock absorbers, providing stability and reducing the stress on the compromised joint.
Strengthening muscles to support joints
When the muscles surrounding an arthritic joint are strengthened, they become more capable of handling the forces generated during movement. This, in turn, alleviates the stress on the affected joint, thereby reducing discomfort and fostering improved alignment. Additionally, strong muscles can play a crucial role in mitigating muscle irregularities commonly associated with osteoarthritis. These irregularities often develop due to modified motion dynamics caused by sensations of pain and rigidity.
Exercises and routines
Physical therapists create tailored exercise routines that focus on enhancing muscle strength, flexibility, and overall joint function. These routines are designed to be progressive, starting with gentle exercises and gradually advancing as the muscles adapt and strengthen.
- Range of motion exercises: These help maintain and improve joint flexibility. Gentle movements are performed to prevent stiffness and maintain the joint’s functional capacity.
- Strengthening exercises: Targeted exercises for specific muscle groups surrounding the affected joint are crucial. For example, if knee osteoarthritis is a concern, exercises that target the quadriceps and hamstrings are often incorporated. These exercises include leg lifts, squats, and seated leg extensions.
- Resistance training: This involves using resistance bands, weights, or even body weight to gradually increase muscle strength. Resistance training builds muscle mass, which can be especially beneficial for stabilising and supporting arthritic joints.
- Low-impact aerobic exercises: Activities like walking, cycling, and swimming promote cardiovascular fitness without putting excessive strain on the joints. These exercises help maintain a healthy weight, which is important for reducing the load on weight-bearing joints.
- Balance and coordination exercises: These exercises enhance proprioception (awareness of joint position) and balance, reducing the risk of falls that could further aggravate joint pain.
Surgical options for Osteoarthritis
When traditional treatments for osteoarthritis don’t provide sufficient relief, surgical interventions may be considered. Two common surgical options are joint replacement surgery and joint fusion. Let’s delve into these procedures from a medical perspective and understand them better.
Joint replacement surgery
Joint replacement surgery, also known as arthroplasty, is a procedure where the damaged joint is replaced with an artificial joint, typically made from metal and plastic components. This surgery is often recommended when the joint’s cartilage has significantly worn away, causing pain, inflammation, and limited mobility.
Procedure: During joint replacement surgery, the surgeon removes the damaged surfaces of the joint, including the cartilage and sometimes a portion of the bone. The artificial joint components are then meticulously positioned and attached to the remaining healthy bone. The replaced joint functions similarly to a natural joint, allowing for improved movement and reduced pain.
Benefits: Joint replacement surgery aims to restore joint function, reduce pain, and enhance the overall quality of life. With advancements in surgical techniques and implant materials, recovery times have improved, and the longevity of artificial joints has increased.
Joint fusion (Arthrodesis)
Joint fusion involves permanently joining two bones on either side of a damaged joint. This procedure is considered when the joint has lost substantial cartilage, and pain and instability persist despite other treatments.
Procedure: In joint fusion, the surgeon removes the damaged cartilage from the joint’s surfaces and positions the bones in such a way that they grow together over time. This eliminates the joint’s movement but can significantly alleviate pain.
Benefits: Joint fusion can provide pain relief by eliminating the source of friction and inflammation in the damaged joint. However, it does limit movement in that joint.
Pros and cons of surgical intervention
Pros
- Pain relief: Surgery can provide substantial and often long-lasting pain relief, especially in cases of advanced osteoarthritis where non-surgical treatments are no longer effective.
- Improved function: Surgical procedures like joint replacement can significantly improve joint function, allowing patients to regain mobility and engage in activities they might have had to give up due to pain and limitations.
- Enhanced quality of life: Reduced pain and improved mobility can lead to an overall better quality of life, as patients can participate in daily activities, hobbies, and social interactions with greater ease.
- Long-term results: Joint replacement surgery, with proper care and rehabilitation, can offer lasting results, sometimes even decades of improved joint function and pain relief.
- Advanced techniques: Advances in surgical techniques, implant materials, and post-operative care have improved the safety and effectiveness of these procedures.
- Personalised approach: Surgeons can tailor surgical interventions to an individual’s specific condition, optimising outcomes based on factors like age, health status, and joint damage.\
Cons
- Invasive nature: Surgery involves incisions, tissue manipulation, and potential risks of infection and bleeding, which can lead to complications.
- Recovery period: Post-operative recovery can be lengthy and challenging. Patients may need to follow strict rehabilitation protocols to regain strength, mobility, and function.
- Risks and complications: Surgical interventions carry inherent risks, including infection, blood clots, implant failure, nerve damage, and adverse reactions to anaesthesia.
- Limited reversibility: Surgical procedures like joint fusion are generally irreversible; once a joint is fused, its movement is permanently restricted.
- Anaesthesia concerns: Anaesthesia is required for surgical procedures, which can be risky for individuals with certain medical conditions.
- Expense: Surgical interventions can be costly, involving hospitalisation, surgeon fees, anaesthesia, and follow-up care. Costs can vary based on factors like location and insurance coverage.
- Not suitable for everyone: Surgery might not be an option for individuals with certain medical conditions, advanced age, or those who are not healthy enough to undergo the procedure.
- Potential for suboptimal outcomes: While advancements have improved outcomes, there’s still a possibility that surgical interventions might not lead to the desired level of pain relief or joint function.
Alternative therapies to surgery for Osteoarthritis
Injections
Hyaluronic acid injections: This involves injecting hyaluronic acid, a natural joint fluid, into the affected joint to provide lubrication and cushioning. It aims to alleviate pain and improve joint movement.
Platelet-Rich Plasma (PRP) injections: PRP injections use a concentrated form of the patient’s blood platelets to promote tissue healing and reduce inflammation in the joint.
Risks and effectiveness: While both options are considered non-surgical, they carry risks such as infection, pain at the injection site, or allergic reactions. Effectiveness varies among individuals, with some experiencing significant pain relief and improved function while others may see limited benefit.
Recovery time for non-surgical treatments
Typical recovery expectations for injections: Recovery time for these injections is generally minimal. Patients can usually resume light activities shortly after the procedure, but strenuous activities might need to be avoided for a few days to a week.
Maintenance and follow-up treatments: The pain relief from injections is often temporary, lasting from a few months to a year. To maintain the benefits, patients may require periodic injections. The frequency of these follow-up treatments can vary based on the individual’s response and the specific injection used.
Self-management and lifestyle
Managing pain at home:
Heat and cold treatment: Using heat or cold packs can provide relief from discomfort and inflammation linked to osteoarthritis. Warmth eases muscle tension and enhances circulation, whereas cold diminishes swelling and numbs the region.
Supportive gadgets: These encompass implements like braces, splints, or canes that can assist in diminishing pressure on joints and augmenting mobility, thus enhancing the ease of daily tasks.
Practices for mindfulness and unwinding: Techniques such as mindfulness meditation and relaxation routines have the potential to effectively handle pain by decreasing stress and fostering a state of tranquillity.
Ongoing monitoring and support
Regular check-ups: Scheduled visits to medical professionals allow for tracking of osteoarthritis progression, adjusting treatment plans, and addressing concerns.
Support groups and community resources: Joining support groups or using local resources provides emotional support, shares information, and offers coping strategies for living with osteoarthritis.
