Knee sports injuries
Knee sports injuries happen during physical activity or exercise and affect the structures within or around the knee joint. While some injuries are mild and improve with rest, others may need specialist care.
What are knee sports injuries?
The knee is one of the largest and most complex joints in the body, which makes it vulnerable to injury, especially during sports that involve twisting, jumping, or sudden changes in direction.
Knee sports injuries are common among those who take part in physical activity, from occasional runners to professional athletes. These injuries can affect different parts of the knee, including ligaments, cartilage, tendons and surrounding soft tissues.
There are several types of knee sports injuries. Some of the most common include:
meniscus tears – damage to the cartilage that cushions the knee joint, often caused by twisting movements
anterior cruciate ligament (ACL) tears – a serious ligament injury that can cause instability, usually from sudden stops or changes in direction
ligament damage – injuries to ligaments such as the medial collateral ligament (MCL) or posterior cruciate ligament (PCL), often due to impact or overstretching
articular cartilage damage – wear or injury to the smooth cartilage covering the bones, which can cause pain and stiffness
iliotibial band (ITB) syndrome/runner’s knee – pain around the front of the knee, often linked to overuse or poor alignment
patella tendonitis (jumper’s knee) – inflammation of the tendon connecting the kneecap to the shinbone, commonly caused by repetitive jumping or running
fat pad impingement – irritation of the soft tissue beneath the kneecap, often due to overuse or trauma
These conditions vary in severity, but all can affect your ability to move comfortably and take part in sport or daily activities.
Early assessment and treatment can help reduce pain, restore movement and lower the risk of long-term problems. At Welbeck, our knee specialists assess and treat a wide range of knee conditions in our state-of-the-art Orthopaedic centre.

More information
Symptoms can vary depending on the type and severity of the injury. Some develop suddenly after an incident, while others come on gradually with overuse.
Common symptoms include:
pain in or around the knee
swelling or inflammation
stiffness or reduced range of movement
a feeling of instability or the knee ‘giving way’
difficulty putting weight on the leg
clicking, popping, or locking sensations
tenderness when touching the knee
weakness in the joint
If you notice any of these symptoms, especially after a sports injury, it’s important to seek medical advice.
Knee injuries often occur when the joint is put under sudden or repeated stress. This can occur during sports, exercise, or even everyday activities.
Common causes include:
sudden twisting or pivoting movements
landing awkwardly after a jump
direct impact to the knee
overuse from repetitive activities such as running or cycling
poor training technique or lack of conditioning
inadequate warm-up or stretching
Risk factors
Some factors can increase your risk of developing a knee sports injury:
playing high-impact sports such as football, rugby, or basketball
weak muscles around the knee, hips, or core
poor footwear or unsuitable equipment
previous knee injuries
training too intensely without enough rest
poor alignment of the legs or kneecaps
If you’re experiencing knee pain or have had a sports injury, your care will begin with an initial consultation with a specialist.
Your consultant will ask about your symptoms, how the injury happened, and your medical history. They’ll also examine your knee to assess movement, strength, and stability.
In some cases, a diagnosis can be made during a consultation. However, further tests may be needed to confirm the diagnosis or assess the extent of the injury. These may include:
X-ray – to check for fractures or bone issues
MRI scan – to assess soft tissues such as ligaments, cartilage, and tendons
ultrasound scan – to examine tendons and soft tissue injuries. Ultrasound can also be used to help guide the drainage of fluid and pain relief injections into the joint
CT scan – to assess bone anatomy, especially if there’s a fracture
These tests help your consultant recommend the most appropriate treatment plan for your condition.
While not all injuries can be prevented, there are steps you can take to reduce your risk.
These include:
warming up properly before exercise
strengthening the muscles around your knees, hips, and core
using the correct technique during sports and training
wearing supportive and well-fitting footwear
gradually increasing intensity and duration of exercise
allowing time for rest and recovery between sessions
maintaining a healthy weight to reduce pressure on the knees
Taking these steps can help protect your knees and improve overall performance.
Most knee injuries improve with the right treatment, but if left untreated, they can lead to longer-term problems.
Possible complications include:
ongoing pain or swelling
reduced mobility or stiffness
chronic instability of the knee
difficulty returning to sport or physical activity
early wear of the joint (osteoarthritis)
In some cases, complications can still occur despite treatment, although this is less common. Early diagnosis and appropriate care can help reduce these risks.
Treatment depends on the type and severity of the injury, as well as your activity level and overall health.
Your consultant will create a personalised treatment plan, which may include:
rest and activity modification – avoiding movements that worsen symptoms
physiotherapy – exercises to improve strength, flexibility, and stability
pain relief medication – such as paracetamol or anti-inflammatory drugs
bracing or support – to stabilise the knee during recovery
injections – such as steroids or hyaluronic acid to reduce pain and inflammation
minimally invasive procedures – such as arthroscopy to repair damage inside the knee, like the meniscus repair procedure used to treat meniscus tear
surgery – in more severe cases, such as ligament reconstruction, like ACL reconstruction, or cartilage repair
Many people recover well with non-surgical treatments, but some injuries may require surgery to restore full function.

Frequently asked questions
It depends on the type and severity of your injury. In some cases, low-impact activities may still be possible, but continuing high-impact sport could worsen the condition. A specialist can advise you on what is safe.
Recovery time varies widely. Minor injuries may improve within a few weeks, while more serious injuries, such as ligament tears, can take several months. Your recovery will depend on your treatment plan and how well you follow it.
No, many ligament injuries can be treated without surgery using physiotherapy and rehabilitation. Surgery is usually only recommended for more severe injuries or when the knee remains unstable.
You should seek medical advice if your pain is severe, doesn’t improve after a few days of rest, or is affecting your ability to walk or exercise. Early assessment can help prevent further damage and speed up recovery.
