Knee pain is a common concern among adults of all ages, from active individuals who exercise regularly to older adults who experience discomfort during daily activities. Many patients worry that continuing to exercise may worsen their knee condition, while others fear that stopping activity altogether could lead to stiffness and weakness.
So, can you still exercise with knee pain? The answer depends on the cause of the pain, its severity, and the type of exercise being performed. In this article, we’ll delve into what’s safe, what’s not, and when you should seek medical attention.
Is It Safe to Exercise With Knee Pain?
Exercising with knee pain is not always harmful. Mild or occasional discomfort, especially after activity, may be temporary and due to muscle fatigue, overuse, or minor strain. In such cases, appropriate exercise can help improve strength, flexibility, and joint support.
However, pain that is sharp, persistent, worsening, or associated with swelling or instability may indicate an underlying injury or condition that requires medical attention. Exercising through unreasonable pain can lead to further damage, delayed healing, and long-term joint problems. Knowing when to continue and when to stop is key.
Exercises That Are Safe for Knee Pain
For many patients, low-impact exercises are the safest and most beneficial option.
- Walking on flat, even surfaces can help maintain mobility without excessive joint stress. Proper footwear and pacing are important.
- Cycling, whether on a stationary bike or outdoors, allows knee movement with minimal impact while strengthening the surrounding muscles.
- Swimming and water-based exercises are excellent for knee pain, as water buoyancy reduces joint loading while allowing full movement.
- Strengthening exercises targeting the quadriceps, hamstrings, gluteal muscles, and hip stabilisers can improve knee support. These exercises should be done in a controlled manner and within a pain-free range.
- Gentle stretching and flexibility exercises can reduce stiffness and improve joint movement, especially in patients with arthritis.
Exercises to Avoid or Modify
Certain activities may aggravate knee pain, especially if done incorrectly or too aggressively. These include:
- High-impact exercises such as running, jumping, and plyometric workouts can increase joint stress and should be limited if pain is present.
- Deep squats, lunges, and kneeling positions may worsen pain in patients with cartilage damage or meniscus injuries.
- Sports that involve sudden direction changes, pivoting, or rapid acceleration, such as football or basketball, can increase the risk of further injury.
Ignoring pain signals and pushing through discomfort often leads to worsening symptoms and prolonged recovery, and should be avoided.
Warning Signs You Should Stop Exercising
It is important to stop exercising and seek medical advice if your knee pain is accompanied by swelling, locking, catching, or a feeling that the knee is giving way. Additionally, pain that persists despite rest, worsens over time, or interferes with daily activities or sleep should not be ignored. Lastly, sudden pain after a fall or injury also warrants medical attention.
How an Orthopaedic Specialist Can Help
An orthopaedic specialist can accurately diagnose the cause of knee pain through a detailed clinical assessment and appropriate imaging such as X-rays or MRI scans.
Based on the diagnosis, a personalised treatment plan can be developed. This may include physiotherapy, activity modification, medications, injections, or surgery (e.g. knee replacement surgery or ACL reconstruction surgery).
Early assessment helps prevent long-term damage and allows patients to return to safe and effective physical activity sooner.
