Estimated Reading Time: 6 minutes read

Knee swelling after exercise is a common problem that can affect anyone, from athletes to casual exercisers. When the knee joint accumulates excess fluid, it can cause pain, stiffness, and discomfort, making it difficult to move. This condition can result from various factors such as overuse, injuries, or underlying health conditions like arthritis. To prevent knee swelling, it is essential to identify the activities that trigger it and take appropriate measures.

One of the first steps in managing knee swelling is to monitor which activities are causing the problem. You should reduce the intensity of these activities, take breaks, or wear a brace for extra support. Stretching and strengthening exercises can also support the knee joint and improve flexibility. It is also a good idea to consult with a healthcare professional, such as a primary care physician or physical therapist, to get a proper diagnosis and personalized treatment plan.

By adopting a comprehensive approach that includes modifying your activities, performing targeted exercises, and seeking professional advice, you can significantly reduce the risk of knee swelling and maintain healthy joints. In this article, we will explore the causes and symptoms of knee swelling, provide a list of beneficial exercises, and offer tips on how to care for your knees.

Causes of Knee Swelling

1. Overuse Injuries: Repetitive strain from activities like running can lead to knee swelling. This is common in conditions like patellofemoral pain syndrome (runner’s knee)​​​​.
2. Acute Injuries: Sudden injuries such as ligament tears or meniscus injuries can cause immediate swelling​​.
3. Arthritis: Both osteoarthritis and rheumatoid arthritis can lead to chronic knee swelling due to inflammation​​.
4. Bursitis: Inflammation of the bursae, small fluid-filled sacs in the knee, can result in swelling​​.
5. Tendonitis: Overuse of the tendons around the knee can cause inflammation and swelling​​.
6. Infections: Though rare, infections within the knee joint can cause significant swelling and pain​​.

Symptoms of Knee Swelling

1. Pain: Swelling is often accompanied by pain, especially when moving the knee.
2. Stiffness: Fluid accumulation can make it difficult to bend or straighten the knee fully​​.
3. Warmth: The affected area may feel warm due to inflammation.
4. Redness: The skin around the knee may appear red and inflamed.
5. Weakness: Swelling can weaken the muscles around the knee, leading to instability.
6. Difficulty Weight Bearing: Severe swelling may make it hard to put weight on the affected leg.

Effective Exercises to Prevent Knee Swelling

Engaging in specific exercises can help strengthen the muscles around the knee, improve flexibility, and reduce the risk of swelling. Here are some recommended exercises:

1. Clamshells

• Start by playing on your side with both knees bent.
• Keep your feet in contact with each other, and then rotate your top leg up. 
• Make sure your spine is in alignment and your hips don’t rock back! If you think your back is moving, do a smaller range of motion.
• Rotate your top leg back down to the starting position.
• Do this 10 times for one set, and complete 3 sets.

2. Standing Hip Lifts

• Stand tall with one hand placed on a bed or chair. Balance on your left leg, keeping a soft bend in your knee to keep from locking out.
• Leading with your heel, lift your right leg out to the side. Be sure not to lean to the left. 
• Repeat 10 times per leg.
• Complete 3 sets of the exercise.

3. Standing Hip Extension

• Stand tall with your hands placed on a steady surface. You can use a counter, sink, or chair (no chairs with wheels) to hold on to for balance. 
• Shift your weight onto your left leg, keeping a soft bend in your left knee to keep it from locking out.
• Then, keeping your toes pointed forward and your right leg straight, lift your right leg back a few inches and lower it back down.
• Repeat 10 times per leg for 3 sets.

4. Bridges

• Lie on your bed or floor (a bed is better if you have difficulty getting on the floor). Again, ensure your knees are bent at about 90 degrees, and your feet are flat on the floor. 
• Lift your hips off the ground, using your hands to help push your hips up if needed.
• Slowly lower your hips to the bed or floor and repeat 10 repetitions for 3 sets.

5. Knee Lifts

• Sit at the edge of your chair, holding the sides for support if needed.
• Lift your right knee slowly towards your chest.
• Return to the starting position with control.
• Repeat the motion with the left leg.
• Alternate between legs.
• Keep your back straight and avoid leaning back.
• Aim for a total of 10 reps, alternating between legs.

6. Full Leg Lifts

• Lie on your back with one leg bent and the other leg straight and together.
• Lift your straight leg up towards the ceiling, raising your buttocks off the floor.
• Slowly lower your leg back down, stopping just above the floor. Hold for 5 seconds briefly.
• Repeat the movement for 10 repetitions and 3 sets.

7. Standing Hamstring Curl

These exercises focus on strengthening the hip and leg muscles, providing better support to the knee joint, and reducing the likelihood of swelling.

3. Stretch Regularly: Incorporate stretching exercises into your routine to maintain flexibility and reduce stiffness​​.
4. Strengthen Muscles: Engage in exercises that strengthen the muscles around the knee joint​​.
5. Rest and Ice: Rest your knee and apply ice to reduce swelling after intense activities​​.
