The most effective exercises for knee osteoarthritis are low-impact, strength-building movements that support the joint without overloading it. Physiotherapy in Tilburg, particularly at specialized practices, focuses on targeted exercise therapy to reduce pain, improve mobility, and help patients regain their independence. Below, you will find answers to the most common questions about exercising safely and effectively with knee osteoarthritis.
Which exercises are most effective for knee osteoarthritis?
The most effective exercises for knee osteoarthritis are those that strengthen the muscles surrounding the knee, particularly the quadriceps and hamstrings, while minimizing stress on the joint itself. Strength training, aquatic exercises, and cycling are consistently recommended because they build load capacity in the knee without causing excessive wear.
Effective exercises typically include:
- Leg press and seated leg extensions to build quadriceps strength
- Straight leg raises to activate the upper leg without bending the knee under load
- Stationary cycling for joint mobility and cardiovascular fitness
- Water-based exercises to reduce gravitational load while still training muscles
- Glute bridges to strengthen the hips and reduce compensatory strain on the knee
The key principle is progressive loading: starting with manageable resistance and gradually increasing it as the joint adapts. This approach is what makes exercise therapy so effective for osteoarthritis, as it trains the body to tolerate more activity over time.
How does exercise reduce pain in an arthritic knee?
Exercise reduces pain in an arthritic knee by strengthening the muscles that support and stabilize the joint, which reduces the direct load placed on the cartilage. Stronger surrounding muscles act as shock absorbers, distributing force more evenly and easing the pressure that causes pain during daily movement.
Beyond mechanical support, regular movement stimulates the production of synovial fluid, which lubricates the joint and helps nutrients reach the remaining cartilage. This is why people with knee osteoarthritis often feel stiffer after rest and more mobile after gentle movement. Physical activity also reduces inflammation over time and improves overall joint function.
The result is a positive cycle: as the muscles grow stronger and the joint moves more freely, everyday activities such as climbing stairs or walking become less painful, which in turn encourages more movement.
What exercises should you avoid with knee osteoarthritis?
With knee osteoarthritis, you should avoid high-impact and deep-loading exercises that place sudden or excessive force on the joint. These can accelerate cartilage breakdown and cause pain flare-ups that set back your progress significantly.
Exercises and activities to approach with caution include:
- Running on hard surfaces, especially if you are not yet conditioned for it
- Deep squats and lunges that take the knee well past 90 degrees under load
- Jumping and plyometric exercises due to the high impact on landing
- Leg press with excessive weight before the joint has built sufficient tolerance
- High-intensity sports such as football or tennis without proper preparation
This does not mean these activities are permanently off-limits. With the right guidance and progressive build-up, many people with knee osteoarthritis return to activities they thought were out of reach. The key is building the joint’s load capacity first.
How many times a week should you exercise with a bad knee?
Most people with knee osteoarthritis benefit from exercising three to five times per week, combining strength training with lighter activity such as walking or cycling on alternate days. Consistency matters more than intensity, and rest days allow the joint and muscles to recover and adapt.
A practical weekly structure might look like this:
- Two to three days of targeted strength exercises for the knee and surrounding muscles
- Two days of low-impact activity such as swimming, cycling, or walking
- One to two rest days or very light movement such as stretching
It is equally important to listen to your body. Some pain during exercise is expected, but sharp or prolonged pain after a session is a signal to reduce intensity. A physiotherapist can help you find the right balance and adjust your program as your strength and tolerance improve.
When should a physiotherapist guide your knee osteoarthritis exercises?
A physiotherapist should guide your knee osteoarthritis exercises when your pain is affecting daily life, when you are unsure which exercises are safe, or when you have tried exercising independently without meaningful improvement. Professional guidance is also essential before and after knee surgery to ensure the best possible outcome.
Specific situations that call for physiotherapy guidance include:
- Pain that limits walking, stair climbing, or sleep
- Uncertainty about how to exercise safely without worsening the joint
- A recent diagnosis of knee osteoarthritis and no clear plan
- Preparation for a total knee replacement
- Recovery after knee surgery, particularly in the first weeks
- Previous treatments that did not produce lasting results
Exercising under professional supervision ensures that the load on your knee is appropriate for your specific situation, reducing the risk of setbacks and maximizing progress.

Veelgestelde vragen
How long does it take to notice improvement from exercise therapy for knee osteoarthritis?
Most people begin to notice meaningful improvements in pain and mobility within 6 to 12 weeks of consistent exercise therapy, though this varies depending on the severity of the osteoarthritis and how regularly you train. Early gains are often felt as reduced stiffness and easier daily movement before strength improvements become measurable. Staying consistent with your program — even on days when the knee feels uncomfortable — is the most important factor in seeing long-term results.
Can I still exercise during a pain flare-up, or should I rest completely?
Complete rest during a flare-up is generally not recommended, as it can lead to stiffness and muscle loss that make recovery harder. Instead, reduce the intensity and switch to very gentle, low-impact movement such as short walks, light cycling, or water-based exercises that keep the joint mobile without aggravating it. Once the flare-up subsides, gradually return to your regular program rather than jumping straight back to your previous load.
Is walking enough exercise for knee osteoarthritis, or do I need to add strength training?
Walking is a valuable low-impact activity that supports joint health and general fitness, but it is not sufficient on its own to build the muscle strength needed to effectively offload the knee joint. Targeted strength training — particularly for the quadriceps, hamstrings, and glutes — is essential for reducing cartilage stress and improving long-term function. A well-rounded program combines both: walking or cycling for mobility and cardiovascular health, plus two to three strength sessions per week for structural support.
What is the difference between normal exercise discomfort and pain that signals I should stop?
A mild to moderate ache during or shortly after exercise — often described as a 3 to 4 out of 10 on a pain scale — is generally acceptable and expected when training a knee with osteoarthritis. However, sharp, stabbing, or worsening pain during an exercise, or pain that remains elevated for more than 24 hours after a session, is a sign that the load was too high and the program needs to be adjusted. When in doubt, consult your physiotherapist before continuing, as pushing through the wrong type of pain can set your progress back significantly.
Do I need special equipment at home to exercise safely with knee osteoarthritis?
Many effective exercises for knee osteoarthritis — such as straight leg raises, glute bridges, and seated leg extensions with a resistance band — can be performed at home with minimal or no equipment. A resistance band and a sturdy chair are often enough to get started with a basic home program. That said, access to gym equipment such as a leg press machine or stationary bike, ideally under physiotherapy supervision, allows for more precise progressive loading and faster, safer results.
Can exercise therapy help me avoid or delay knee replacement surgery?
Yes — research consistently shows that structured exercise therapy can significantly reduce pain and improve function in people with knee osteoarthritis, sometimes to the point where surgery is no longer necessary or can be safely postponed for years. Exercise therapy is recommended as the first-line treatment for knee osteoarthritis by most international clinical guidelines, precisely because of its effectiveness in improving quality of life without surgical risk. Even for those who do eventually need a knee replacement, being stronger and more mobile beforehand leads to faster recovery and better surgical outcomes.
How do I know if my exercise program is actually working and progressing correctly?
Key signs that your program is working include reduced pain during daily activities like stair climbing or walking, improved range of motion in the knee, and the ability to perform exercises with greater resistance or repetitions than when you started. Tracking these markers — either through a training diary or with the help of a physiotherapist using objective measurements — helps confirm progress and signals when it is time to increase the challenge. If you have been training consistently for 8 to 10 weeks without any of these improvements, it is worth revisiting your program with a professional to identify what needs to change.
