Treating Knee Osteoarthritis: How Physiotherapy Can Help

Pain when climbing stairs, stiffness after sitting for a long time, or a grinding sensation in the knee are common signs of knee osteoarthritis. Many people begin to worry early about surgery or permanent joint damage.

The reassuring news is that surgery is not the first step in most cases. Targeted physiotherapy can significantly reduce pain, improve joint mobility, and support long-term knee function. With the right therapeutic approach, many patients can maintain an active lifestyle for years.

What Is Knee Osteoarthritis?

Knee osteoarthritis, medically known as gonarthrosis, is a degenerative condition of the knee joint. It is characterized by progressive degeneration of the joint complex, including the articular cartilage, subchondral bone, and synovium.

Over time, chronic mechanical stress and age-related changes cause the cartilage to lose elasticity and become more fragile. As cartilage degeneration progresses, the joint may no longer function as smoothly, which can contribute to pain, stiffness, and reduced mobility.

Radiological findings may show joint space narrowing and structural changes in the subchondral bone. The condition can gradually progress from early stages with mild symptoms to advanced disease with persistent pain and significant functional limitation.

Symptoms of Knee Osteoarthritis

The symptoms of knee osteoarthritis usually develop gradually and tend to worsen over time. Early recognition is important in order to get the appropriate treatment.

Morning Stiffness and Pain After Rest

Morning joint stiffness is common in osteoarthritis and usually lasts less than 30 minutes. You may notice increased discomfort after periods of inactivity. However, this symptom often improves with gentle movement.

Pain During Activity, Painful Flare-Ups, and Grinding Sensations

Pain during or after physical activity is a common symptom of knee osteoarthritis. Walking longer distances, climbing stairs, or putting weight on the knee can make the pain worse. In more advanced stages, the pain may become persistent and occasionally occur at night.

Patients may experience episodes of increased inflammation, which can lead to swelling and increased pain. Some people notice that the joint occasionally feels as if it catches or briefly gets stuck during movement.

Causes and Risk Factors

Knee osteoarthritis can develop for several reasons. Besides the natural ageing process, genetic factors can also play a role. Being overweight places additional strain on the knee joint, which can gradually damage the protective cartilage that allows the joint to move smoothly.

Leg alignment problems, such as bowlegs or knock-knees, can place uneven pressure on different parts of the knee. Over time, this imbalance can lead to increased wear in certain areas of the joint.

Previous injuries, such as meniscus tears or cruciate ligament injuries, can also increase the risk. Repeated heavy strain from certain sports or physically demanding jobs may further contribute to joint degeneration.

Diagnosis: How Knee Osteoarthritis Is Identified

Knee osteoarthritis is usually diagnosed through a medical examination. During the assessment, the doctor or physiotherapist evaluates how well the knee moves, how stable the joint is, and when pain occurs.

X-rays taken while standing are often used to look at the knee joint and detect typical changes caused by osteoarthritis, such as reduced space between the bones. In some cases, an MRI scan may be used to provide more detailed images of structures such as cartilage, ligaments, and the meniscus, although this is not always necessary.

Treatment of Knee Osteoarthritis with Physiotherapy

Physiotherapy is an important part of conservative treatment for knee osteoarthritis. The main goals are to reduce pain, improve mobility, and enhance overall joint function.

Manual Therapy

Manual therapy uses hands-on techniques to improve joint mobility and relieve pain. Gentle mobilization can reduce pain and support the natural function of the knee joint. You can learn more about this approach in our manual therapy section.

Medical Training Therapy (MTT)

Medical Training Therapy focuses on the targeted strengthening of the muscles that stabilize the knee joint. Guided strength training using specialized equipment increases joint resilience and improves pressure distribution within the knee.

Over time, stronger surrounding muscles help stabilize the joint and reduce osteoarthritis-related symptoms. Further information is available in our medical training therapy (MTT) section.

Conservative Therapy vs. Surgery: When Is a Knee Prosthesis Necessary?

A total knee replacement, also known as a knee TEP, is generally considered the last treatment option. Surgery is usually recommended only when conservative measures such as physiotherapy, structured exercise, and weight management have been fully explored and daily pain significantly limits quality of life.

With consistent physiotherapy and structured exercise, many patients experience significant improvement in pain and function.

Frequently Asked Questions (FAQ)

How quickly does knee osteoarthritis progress?

The progression varies from person to person. Without appropriate management, osteoarthritis may gradually worsen over time. However, targeted physiotherapy, regular exercise, and weight management can often stabilize the condition or significantly slow its progression for many years.

When is surgery absolutely necessary?

Surgery is usually only considered when non-surgical treatments no longer provide sufficient relief. The decision is always made on an individual basis and depends on the severity of symptoms and how much the knee limits daily activities.

What exercises are most effective for knee osteoarthritis?

Strengthening the thigh muscles, especially the quadriceps, is particularly important. In addition, stabilizing exercises for the hip and trunk muscles help improve joint alignment and reduce stress on the knee.

What helps relieve acute knee pain?

Alongside physiotherapy, gentle low-impact activities such as cycling help maintain joint mobility, improve muscle support, and reduce stiffness. During inflammatory flare-ups, cooling applications such as ice packs can help reduce pain and swelling. 

Temporarily reducing weight-bearing and avoiding excessive joint loading may also relieve symptoms and allow the joint to recover.

Is jogging harmful if I have knee osteoarthritis?

In moderate to advanced knee osteoarthritis, high-impact activities such as jogging can increase joint loading and may worsen symptoms. 

Low-impact activities such as swimming or cycling are generally better tolerated because they strengthen supporting muscles while placing less stress on the knee joint. In early stages, some individuals may still tolerate jogging if symptoms remain stable and training is appropriately adjusted.

Why is exercise important despite pain?

With knee osteoarthritis, it may feel natural to avoid movement when the joint hurts. However, gentle exercise is important because cartilage does not have its own blood supply and relies on movement to receive nutrients. Without regular movement, joints can become stiffer and cartilage may deteriorate more quickly.
