#kneesprain

Knee pain after a twist, fall, or sports injury could be more than a sprain—it may be a meniscus tear. If you notice swelling, knee locking, pain while squatting, or difficulty bending your knee, don't ignore it.

Knee sprains are a common injury, particularly among sportspeople, resulting from overstretching or tearing of one or more knee ligaments. These ligaments ensure the stability of the joint and when they are damaged, the knee becomes unstable and painful.

Causes of a knee sprain

- Sudden movements: A quick change of direction, leaning on an uneven surface or a direct impact can lead to a sprain.

- Sports: Contact sports or sports requiring frequent changes of direction (football, basketball, rugby) increase the risk of sprain.

- Muscle weakness: Insufficient thigh and leg muscles can make the knee more vulnerable.

Symptoms of a knee sprain

Symptoms vary according to the severity of the sprain:

- Pain: Often sharp and immediate, localised in the knee.

- Swelling: Rapid appearance of oedema.

- Ecchymosis: A bruise may appear.

- Instability: Sensation of a ‘loose knee’.

- Difficulty walking: The knee may be stiff and painful.

Treatment of a knee sprain

Treatment depends on the severity of the sprain and is generally based on the RICE protocol:

- Rest: Rest the knee to promote healing.

- Ice: Apply ice to reduce inflammation and pain.

- Compression: Use a compression bandage to limit swelling.

- Elevation: Keep the knee elevated to promote venous return.

In addition, anti-inflammatory medication may be prescribed. Physiotherapy is essential to strengthen the muscles and restore full mobility. In the most serious cases, surgery may be required.

Preventing knee sprains

- Warming up: A thorough warm-up before any physical activity is essential.

- Muscle strengthening: Strengthening the thigh and leg muscles helps to stabilise the knee.

- Appropriate footwear: Choose shoes that offer good support.

- Sport techniques: Learn the right techniques to avoid sudden movements.

In the event of a sprain, it is important to consult a doctor for a precise diagnosis and appropriate treatment.
