Why Does My Knee Hurt After Playing Tennis?

If your knee starts hurting after a tennis match, especially when you walk, bend your knee, or get up from sitting, repeated stops, turns, and lunges may be putting more strain on it than it can comfortably handle.

After a tennis match, you may notice that your knee hurts when you walk to your car, climb stairs, sit down, or get up from a chair. The pain may be concentrated at the front of your knee, just below the kneecap, or along the inner or outer edge. These patterns can develop when the repeated running, braking, and direction changes in tennis place more demand on your knee than it can comfortably handle.

The patellar tendon connects your kneecap to your shinbone and helps you straighten your knee when you push off, lunge, or recover from a low shot. The cartilage beneath the kneecap and other structures around the joint also help your knee handle these movements. When an area becomes irritated or fatigued, normal bending and straightening after a match can become painful, even if you managed to finish playing.

Repeated Stops And Turns Leave Your Knee Sore After Tennis

Your knee has to absorb repeated braking and turning during a tennis match.

Every time you sprint toward a ball and stop suddenly, your knee has to slow your body down before you change direction. Lunging for a wide shot or planting your foot to move back across the court adds more demand, particularly when you repeat these movements throughout a long rally. If your patellar tendon or the area around your kneecap is already irritated, these actions can leave your knee painful after the match ends.

Your Knee Takes More Strain As The Match Continues

As your legs tire, the same tennis movements can become harder for your knee to handle comfortably.

During a long match, your thigh muscles may gradually lose some of their usual endurance, making it harder to control each landing, lunge, and change of direction. Your knee may then take more of the strain during movements that felt manageable earlier in the match. This can explain why you finish playing with an aching knee even though no single movement caused a sudden injury.

Why Your Knee Keeps Hurting After Tennis

Your knee has a hard time healing when blood flow and circulation are limited.

Tendons, ligaments, and other soft tissues naturally receive less blood supply than many other parts of the body. Because of this, they often take longer to heal after repeated stress or injury, leaving you more vulnerable to lingering pain and a cycle of reinjury.

When circulation through the area remains limited, injured tissues have a harder time receiving the vital oxygen and nutrients they need to repair and heal. This can leave your knee feeling stiff, tight, weak, or painful during everyday movement and activity.

What Can Help Your Knee Feel Better

Your knee starts feeling better when blood flow and circulation improve.

Chinese herbs have been used for centuries to promote healthy blood flow and circulation. Their medicinal properties help break up stagnant blood and fluids that remain trapped around injured tissues, interfering with circulation. As circulation improves, blood flows more freely through the area, allowing those tissues to receive the oxygen and nutrients they need to heal properly.

Topical herbal remedies made with these Chinese herbs can help relieve pain while improving blood flow and circulation to injured tissues. The right product depends on your symptoms and whether you're in the acute or chronic stage of recovery.

If you have pain, swelling, inflammation, or bruising, Acute Sinew Liniment helps relieve these symptoms by increasing circulation and dispersing stagnant blood and fluids around the injured area to speed recovery. During the acute stage of healing, getting circulation moving early allows injured tissues to receive the fresh blood, oxygen, and nutrients they need to repair and heal.

If your injured area is especially swollen, red, or warm to the touch after a recent injury or flare-up, Sinew Herbal Ice is also used to reduce swelling and inflammation while restoring normal circulation so you can quickly regain range of motion. While traditional ice is commonly used to reduce swelling, Sinew Herbal Ice acts as an ice alternative to reduce swelling and inflammation while also dispersing accumulated blood and fluids to speed the healing process.

If you no longer have swelling or inflammation, but still have pain, stiffness, weakness, or sensitivity in cold and damp weather, Chronic Sinew Liniment helps relieve these symptoms by strongly stimulating circulation and increasing blood supply to injured tendons and ligaments to promote their healing. This is especially important because tendons and ligaments naturally receive less blood supply, which is why chronic injuries can take longer to heal.

If you have residual pain and stiffness, or the area becomes more painful in cold weather, Sinew Injury Poultice is also used to significantly stimulate circulation to injured tendons and ligaments to further promote their healing. By strongly increasing circulation, it counteracts the reduced blood flow caused by cold weather that commonly aggravates chronic tendon and ligament injuries.

If you exercise, play sports, or do other strenuous activities, Sinew Sports Massage Oil warms and stimulates muscles for exertion and relieves muscle tightness and soreness after activity. Warming and preparing your muscles before activity can improve flexibility, enhance performance, and reduce the risk of injury.

Frequently Asked Questions

You may also find these commonly asked questions helpful.

Why does my knee hurt after playing tennis?

Your knee may hurt after tennis because repeated stops, turns, lunges, and push-offs strain the patellar tendon or other structures around the knee. Fatigue during a long match can make these movements harder to tolerate.

Why does my knee hurt when I walk after playing tennis?

Your knee may hurt when you walk after tennis because the repeated activity has irritated an area involved in bending, straightening, or supporting your leg. Pain that persists or worsens should be evaluated by a healthcare professional.

Can playing tennis cause patellar tendon pain?

Yes. Repeated jumping, lunging, and pushing off can irritate the patellar tendon below your kneecap, causing pain during play or soreness afterward.

Should I keep playing tennis if my knee hurts afterward?

If your knee hurts after playing, reduce or pause activities that aggravate the pain until it improves. Continuing to play through worsening pain may increase the strain on the affected area.

When should I see a doctor for knee pain after tennis?

Seek prompt medical evaluation if you have severe pain, significant swelling, a locked knee, or difficulty bearing weight. Persistent or worsening pain also deserves assessment, especially if your knee feels unstable.
