Knee Arthritis: Symptoms and Treatment Solutions

Knee arthritis makes you ache when walking, feel uncomfortable after sitting for a long time, even unable to sleep well? Knee arthritis is not just aches and pains; it is a sign that the knee joint is inflamed, the articular cartilage is damaged, and mobility is gradually declining.

So what are the appropriate treatment options for your knee arthritis? Let’s explore with Chiro Lifestyle in the article below.

What is Knee Arthritis?

To properly understand knee arthritis, first grasp the knee joint anatomy. The knee is formed by three main bones: the femur, the tibia, and the patella. The ends of these bones are covered by smooth articular cartilage that reduces friction, absorbs shock, and allows the knee to move smoothly. Surrounding the joint are ligaments, tendons, and muscle groups that stabilize the joint and control knee flexion and extension.

is the inflammation and damage occurring in the knee joint. When cartilage loses its smooth surface, the space between the femur and tibia can narrow, causing increased friction between the bone ends during movement. In severe stages, bone surfaces may rub nearly directly against each other, causing pain and reducing mobility.

Common Types of Knee Arthritis

There are many forms of knee arthritis, the most common being knee osteoarthritis, rheumatoid arthritis, and post-traumatic knee arthritis.

Knee Osteoarthritis (Osteoarthritis – OA)

Knee osteoarthritis is the most common form of knee arthritis, often related to cartilage wear from aging, body load, or movement habits. When the cartilage covering bone ends is eroded, the joint surface is no longer smooth. Over time, cartilage breakdown can cause pain, inflammation, stiffness, and reduced range of motion. You typically feel increased pain with activity, improvement with rest, knee crepitus, or a dry sensation when flexing and extending.

Rheumatoid Arthritis (Rheumatoid Arthritis – RA)

Rheumatoid arthritis is an autoimmune disease that occurs when the immune system mistakenly attacks healthy tissues in the body, including the knee joint. Unlike osteoarthritis, which is usually related to mechanical wear, rheumatoid arthritis originates from an internal inflammatory response within the joint.

This immune system misattack inflames the synovial membrane (the lining inside the knee joint). When inflammation persists, the joint can become swollen, warm, painful, stiff, and difficult to move. Rheumatoid arthritis can occur at various ages, not just in older adults.

Post-Traumatic Knee Arthritis

Post-traumatic knee arthritis often appears in people who have had knee injuries such as ligament tears, meniscal damage, dislocations, fractures around the knee, or sports injuries. After trauma, the knee structure can lose stability, causing uneven force distribution across the joint, leading to pain, inflammation, and early degeneration.

Besides the common types mentioned above, you can also have arthritis from gout or septic arthritis. Gouty arthritis is related to uric acid crystal deposition in the joint, causing sudden severe pain, swelling, warmth, and redness. Septic arthritis occurs when bacteria enter the joint, causing severe inflammation, intense pain, swelling, warmth, and sometimes fever.

Symptoms of Knee Arthritis

When people think of arthritis symptoms, many expect swelling, warmth, redness, and pain. Therefore, when the knee is not visibly swollen, not very painful, or not uncomfortable, you may be complacent and assume it is just ordinary knee pain.

In reality, knee arthritis is a silently progressive disease. Common symptoms of knee arthritis include:

• Knee pain: Pain may increase with walking, standing for long periods, climbing stairs, squatting, standing up–sitting down, or repetitive knee use. In early stages, pain may be intermittent; later, it can become persistent and significantly affect daily activities.

• Knee stiffness: A feeling that the knee cannot fully bend or straighten, especially after waking up, sitting for long periods, or low activity. Stiffness makes simple movements like getting out of bed, standing up, or climbing stairs more difficult.

• Knee catching or locking: When the joint cartilage is damaged, the joint surface becomes thin and rough. This can cause the knee to catch, pause, or have difficulty moving smoothly during flexion and extension.

• Grinding or creaking noises in the joint: You may hear clicking, grinding, or feel the joint “rub” when moving. This is a common sign when cartilage is worn down or the joint surface becomes irregular.

• Weakness of muscles around the knee: Due to pain and limited movement, you often use the affected leg less. Over time, muscles around the knee such as the quadriceps or hamstrings can weaken, making the knee less stable and causing symptoms to worsen.

Risk factors for knee osteoarthritis

Recognizing risk factors early helps you proactively protect the knee before pain progresses. Common risk factors include:

Age and sex

The older you are, the more likely knee cartilage will wear down. As cartilage loses smoothness and elasticity, the knee becomes more prone to pain, stiffness, and reduced mobility during activity. According to , the prevalence of chronic knee pain increases significantly in people over 55, and a large proportion of them show radiographic signs of degeneration.

In addition to age, sex also affects the risk of knee degeneration. Postmenopausal women often have a higher risk than men due to hormonal changes, decreased bone density, changes in muscle mass, and reduced ability to support the joint.

Knee injuries

Injuries such as ligament tears, meniscus damage, dislocation, or severe impact to the knee can alter joint stability. Even after post-injury pain subsides, old injuries can have lasting effects. If not properly rehabilitated, you are at risk for recurrent knee pain, stiffness, muscle weakness around the knee, and progression to osteoarthritis years later.

Overweight and obesity

The knee is a major weight-bearing joint. Therefore, the higher the body weight, the greater the pressure on the knee, especially when walking, climbing stairs, standing for long periods, squatting, or rising from a seated position. Repeated pressure over time can accelerate cartilage wear, making the joint more prone to pain, inflammation, and reduced flexibility.

Lower limb deformities or malalignment

Conditions like bow legs, knock knees, or knee malalignment can cause uneven distribution of body weight across the joint surface. When one side of the joint bears increased load for a prolonged period, the cartilage in that area is more likely to wear prematurely, increasing the risk of knee pain and osteoarthritis.

In addition, flat feet can also affect the knee joint's biomechanics. Some studies report can contribute to altered knee mechanics and increase the risk of medial knee pain, especially in older adults.

Other Health Conditions

Some underlying medical conditions can increase the risk of knee arthritis or make pain, swelling, and stiffness more complex. For example, gout can cause acute joint inflammation when uric acid crystals deposit in the joint, leading to knee pain. Conditions such as diabetes, high cholesterol, iron metabolism disorders, or vitamin D deficiency can also affect bone and joint health, metabolism, and the tissue's ability to recover.

How is Knee Arthritis Diagnosed?

Diagnosing knee arthritis based on symptoms alone is not sufficient; clinicians need to combine physical examination with imaging. Typically, the clinician will examine the knee, assess the pain location, degree of swelling, range of motion, gait, and history of injury or underlying conditions. You may then be referred for X-rays to look for bone spurs, malalignment, or signs of degeneration.

In some cases, clinicians may order an MRI or CT scan to better evaluate the menisci, ligaments, articular cartilage, and surrounding soft tissues. If rheumatoid arthritis, gout, or septic arthritis is suspected, blood tests may be performed to support the diagnosis.

How is knee arthritis treated if you want to avoid injections or surgery?

Aside from interventions like intra-articular injections or surgery (which have specific indications), conservative treatment is the preferred option for most mild to moderate cases of knee arthritis. What methods can reduce pain, improve mobility, and protect the knee joint naturally?

Weight Management

Maintaining a healthy weight is one of the most important ways to reduce pressure on the knee cartilage. When body weight decreases, the knee bears less load during daily activities such as walking, prolonged standing, or climbing stairs.

, every 1 pound (about 0.45 kg) of weight loss can reduce approximately 4 pounds (1.81 kg) of force on the knee joint. In particular, for people with knee osteoarthritis (OA), weight loss has been shown to effectively improve pain, stiffness, and functional ability.

Orthotic Devices

In some cases of knee arthritis, you may use knee braces, orthotic shoe insoles, or mobility aids such as canes and walkers to offload the joint. Orthotic devices are often useful for people with lower limb malalignment, flat feet, unstable knees, or pain that increases with walking. These devices help stabilize the knee, redistribute pressure across the cartilage surface, and make movement easier.

However, these are mechanical support solutions and their benefits typically require time and persistence. When the brace is removed or insoles are discontinued, pressure on the injured joint may return. Therefore, you should combine orthotic devices with rehabilitation and strengthening exercises for the muscles around the knee. This approach helps better support the knee, reduce dependence on assistive devices, and improve long-term mobility.

Physical Therapy and Rehabilitation

Physical therapy and rehabilitation not only reduce pain but also improve range of motion and increase strength of the muscle groups that support the joint. When the muscles around the knee are stronger, the knee is better supported, thereby reducing direct pressure on the cartilage.

In addition to condition-specific rehabilitation exercises, clinicians may combine other physical therapy technologies such as , high-intensity laser, electrical stimulation therapy, or . These methods help reduce pain, increase circulation, relax soft tissues, and promote recovery of the injured knee region.

Chiropractic Spinal Therapy

When treating knee osteoarthritis with chiropractic care, practitioners typically evaluate more than just the knee. They assess the entire kinetic chain including the lumbar spine, pelvis, hip joints, knees, ankles, and feet. If one link in this movement chain is misaligned or restricted, load distribution to the knee can become abnormal, increasing pressure on already damaged cartilage.

Through manual adjustments, chiropractors correct imbalances in the knee joint, pelvis, and spine. When these structures move in proper alignment, forces transmitted to the knee are distributed more evenly, reducing pressure on the injured cartilage. Chiropractic has the advantage of being drug-free, non-surgical, and minimizing risks commonly associated with long-term painkiller use or invasive interventions.

At Chiro Lifestyle, our knee osteoarthritis treatment plans combine chiropractic adjustments, advanced physical therapy technology, and functional rehabilitation. This integrated approach not only reduces pain but also improves mobility, decreases recurrence, and protects the knee joint for more sustainable long-term outcomes.
