Arthritis in Knee: Symptoms, Causes, and Treatment Options

Arthritis in Knee: Symptoms, Causes, and Treatment Options

Arthritis in the knee, a prevalent joint condition, manifests through pain, swelling, and stiffness, significantly impacting mobility and daily activities. This degenerative autoimmune ailment stems from various factors like age-related wear, injuries, or inflammatory conditions affecting the knee joint. Managing knee arthritis often necessitates a comprehensive approach, with physiotherapy playing a pivotal role.

Physiotherapy focuses on enhancing joint mobility, strengthening surrounding muscles, and improving overall function. Tailored exercises help maintain or increase the range of motion, while strength training bolsters the muscles supporting the knee, reducing strain on the joint. Additionally, physiotherapists utilize modalities like ultrasound, heat, or cold therapies to alleviate pain and inflammation.

The significance of physiotherapy lies in its ability to not only manage immediate discomfort but also in its long-term impact on slowing disease progression. By promoting proper joint alignment, reducing stiffness, and enhancing muscle support, physiotherapy empowers individuals to manage knee arthritis better, restoring mobility and enhancing quality of life.

What is Arthritis in the Knee?

Arthritis in the knee refers to inflammation and degeneration of the knee joint, resulting in pain, swelling, and limited mobility. It commonly stems from wear and tear, injuries, or underlying conditions impacting daily activities and mobility due to joint discomfort and stiffness in the knee.

The major types of arthritis that affect the knee 

Based on the location and intensity of the condition, several types of arthritis affect the knee. Understanding this factor can help manage the condition and pursue the most effective treatment for the same.


Osteoarthritis, the most prevalent form of arthritis, entails the gradual breakdown of cartilage in joints, including the knees. It leads to pain, stiffness, and reduced mobility, often associated with aging or joint injuries. Osteoarthritis in the knee impedes movement, causing discomfort during activities, and may require interventions like medication, physiotherapy, or, in severe cases, surgery for management.

Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune condition causing joint inflammation, including the knees. It leads to pain, swelling, and stiffness, often affecting multiple joints symmetrically. Unlike osteoarthritis, it can occur at any age and can lead to joint deformities if untreated.

Treatment involves medications to manage symptoms, physical therapy, and sometimes surgical interventions to alleviate joint damage.

Posttraumatic Arthritis

Posttraumatic arthritis develops after a joint injury, such as a fracture or severe sprain, affecting the knee. Over time, the injured area deteriorates, causing pain, swelling, and limited movement. This condition manifests years after the initial injury and resembles osteoarthritis symptoms. Management involves pain relief measures, activity modifications, and in severe cases, surgical intervention to address joint damage resulting from the trauma.

Causes of Arthritis in the Knee

Arthritis can be caused by several factors, such as genetics, autoimmune conditions, and physical strains. 

Age-Related Factors

Age-related factors contribute significantly to knee arthritis, as wear and tear on the joints over time can degrade cartilage, leading to osteoarthritis. As individuals age, the risk of joint degeneration increases due to natural changes in joint structure and function. This age-related wear diminishes the joint's ability to repair itself, often resulting in the onset or exacerbation of knee arthritis.

Injury and Overuse

Injuries and overuse greatly impact knee arthritis. Traumatic injuries like fractures or ligament tears can increase the risk of posttraumatic arthritis. Repetitive knee stress from activities like running or occupations requiring kneeling can accelerate joint wear, potentially leading to osteoarthritis. Both acute injuries and chronic overuse significantly contribute to the development and progression of knee arthritis.

Genetic and Lifestyle Factors

Genetic predisposition plays a role in knee arthritis development, where certain genes can make individuals more susceptible to joint degeneration. Lifestyle factors such as obesity exert added stress on knee joints, increasing the likelihood of osteoarthritis. Additionally, poor posture, inadequate exercise, and occupational hazards that strain the knees contribute to the progression of knee arthritis in individuals susceptible to genetic factors.

Early Symptoms of Arthritis in the Knees

Keeping an eye out for some of the common symptoms can help identify the condition and seek medical help early. This can improve quality of life and provide long-term support based on the condition.

Joint stiffness

Joint stiffness in knee arthritis involves difficulty moving the knee freely, often upon waking or after prolonged periods of inactivity. It presents as a sensation of resistance or limited mobility, making it challenging to extend or flex the knee fully. Stiffness typically accompanies pain and swelling, impacting mobility and hindering daily activities that require bending or straightening the knee.

Knee buckling

Knee buckling refers to a sudden, unexpected giving way or collapsing of the knee joint while weight-bearing or in motion. It often occurs due to weakened muscles, ligament instability, or underlying joint issues like arthritis. Buckling episodes can lead to falls, causing injury or increasing the risk of further joint damage, impacting daily activities and necessitating medical assessment for proper diagnosis and management.

Joint pain 

Joint pain in arthritis manifests as discomfort or aching in the knee, varying from mild to severe. It often worsens during movement or weight-bearing activities like walking or climbing stairs. The pain might be accompanied by swelling and tenderness around the knee joint, hindering mobility and impacting daily activities, signaling the presence of arthritis in the knee joint.

How to Treat Arthritis in the Knee

There are several ways to treat arthritis in the knee based on medical conditions, history, and the type of arthritis. Several options can be used together to ensure an effective treatment plan.

Non-Surgical Treatments

Non-surgical treatments for knee arthritis include pain management with over-the-counter medications or prescription drugs, physical therapy to strengthen muscles and improve joint flexibility, assistive devices like braces or orthotics for support, lifestyle modifications, weight management, and corticosteroid or hyaluronic acid injections to alleviate pain and inflammation, aiming to improve knee function and reduce discomfort without surgical intervention.

Surgical Options

Surgical options for knee arthritis encompass procedures like arthroscopic debridement, which involves removing damaged tissue. Osteotomy adjusts bone alignment to relieve pressure. Joint fusion or replacement (arthroplasty) replaces the damaged joint surfaces with prosthetics. These surgeries aim to reduce pain, improve mobility, and restore knee function, often considered when non-surgical methods fail to alleviate symptoms adequately.

Physiotherapy to Treat Arthritis in the Knee

Physiotherapy for knee arthritis includes exercises to strengthen muscles around the knee, enhance stability, and reduce joint stress. Modalities like ultrasound or electrical stimulation help alleviate pain and inflammation. Manual therapies aid in restoring joint mobility, while education on proper posture and movement techniques supports better knee function. Physiotherapy plays a vital role in managing symptoms and improving overall knee health for arthritis.

Lifestyle Changes and Home Remedies

Lifestyle changes and home remedies for knee arthritis involve weight management to reduce joint stress. Regular low-impact exercises like swimming or cycling maintain joint mobility. Hot or cold therapy alleviates pain and swelling. Using assistive devices and ergonomic modifications at home or work lessens knee strain. Additionally, a balanced diet rich in anti-inflammatory foods may help manage knee arthritis symptoms.

Managing Pain and Improving Joint Health

For knee arthritis management, pain relief strategies like medications, injections, or topical treatments are crucial. Tailored exercise programs focusing on low-impact activities enhance joint flexibility and strength. Assistive devices and orthotics aid in aligning and supporting the knee, reducing strain. Weight management helps alleviate joint pressure. 

Hot or cold therapy offers pain and swelling relief. Regular monitoring by healthcare professionals and lifestyle adaptations, including proper nutrition and ergonomic adjustments, collectively contribute to improved knee health and effective pain management in arthritis.

Importance of Physiotherapy Treatment for Arthritis in the Knee

Physiotherapy is integral for knee arthritis, offering tailored exercises to strengthen muscles around the knee, enhancing joint stability and reducing stress. Modalities like ultrasound or electrical stimulation aid in pain relief and inflammation reduction. Manual therapies restore joint mobility and function. Education on proper movement techniques and posture empowers individuals to manage symptoms effectively, promoting better knee health and improved quality of life despite arthritis-related challenges.
