Is it a knee sprain? (Knee Sprain) – Let's find out exactly what this is!

Sometimes in our lives, even a small accident can cause a knee sprain, right? Maybe it happens while playing, running, going down stairs, or even just tripping and falling. If you have pain in your knee, swelling, and difficulty moving it, there is a high chance that it is a knee sprain, that is, a knee sprain . So today, let's talk about these knee sprains.

What is a Knee Sprain?

Simply put, a knee sprain is when the ligaments in your knee joint are stretched or torn. Think of it like a rubber band that snaps when pulled too hard. This is exactly what happens.

Our knees are one of the largest joints in our body. They connect our thigh bone, the femur , to our shin bone, the tibia . These knees help us bend, extend, and move our legs.

Ligaments are strong, rope-like bands of tissue that hold our muscles and bones together. They also help prevent joints from moving around unnecessarily and help joints move only in the right direction.

If you have knee pain, swelling, or difficulty moving or using your knee (especially after an accident or fall), you should definitely see a doctor .

What are the types of knee sprains?

There are four main types of ligaments in our knee joint. These are:

• Medial Collateral Ligament (MCL): Runs along the inside of the knee.
• Lateral Collateral Ligament (LCL): Runs along the outside of the knee.
• Anterior Cruciate Ligament (ACL): Located on the front, inside of the knee.
• Posterior Cruciate Ligament (PCL): Located on the back, inside of the knee.

Most often, the collateral ligaments on either side of the knee, either the MCL or the LCL, are sprained, meaning they are damaged. However, any one of these ligaments, and sometimes several ligaments, can be sprained in a single accident.

How common are knee sprains?

In fact, the knee is one of the most easily injured joints in our body. These sprains are also very common, especially among athletes.

What are the symptoms of a sprained knee?

These are the most common symptoms of a sprained knee:

• Knee pain: Pain may occur, especially on either side of the knee. This pain may increase when the knee is moved or used.
• Swelling:The knee is swollen.
• Instability: The knee may feel weak, lose control of its movement, or give way. Some people even say it feels like "the knee is dead."
• Reduced range of motion: It is difficult to bend or straighten the knee normally, and it causes pain when doing so.

Imagine that you suddenly changed direction while playing cricket and twisted your knee. If that happens, you suddenly hear a "cracking" sound, your knee starts to hurt, and then swells up after a while, it could be a sprain.

What are the causes of knee sprains?

Simply put, a sprain can occur when the knee is forced beyond its normal range of motion. This can happen in any direction. For example, if the knee is forced to bend, extend, or twist excessively from side to side, a sprain can occur.

The most common causes of knee sprains are:

• Sports accidents: This is the main cause. This risk is higher in sports that involve running, jumping, sudden stops, and changes of direction.
• Falls: Even if you trip and fall while walking normally, you can still sprain your knee.
• Repetitive Strain Injuries: These injuries can occur from overuse of the knee during training, or from continuous use of the legs and knees in the same way for work, sports, or hobbies.

Risk factors for knee sprains

Although anyone can sprain a knee, athletes and people who do physical work are at higher risk. This risk is especially high for those who play sports that require sudden stops, twists, and changes in direction. For example:

• Soccer
• Basketball
• Rugby
• Tennis
• Skiing
• Games like ice hockey.

Our exercise habits can also affect this:

• Suddenly increasing the amount or intensity of exercise.
• Starting a new sport or exercise without proper equipment or training (for example, doing exercises with incorrect postures, or starting a high-impact sport before learning how to play safely).
• Playing a sport that puts pressure on the knee joints all year round, without any rest.

How to recognize knee sprains?

A doctor will diagnose a knee sprain through a physical exam . Your doctor will examine the injured knee and check its range of motion (perhaps even comparing it to your other, uninjured knee).

You should tell your doctor when you first felt the symptoms, especially if you know exactly how the accident happened and what caused it.

What tests do doctors use to diagnose diseases?

During the physical exam, your doctor may ask you to do some special clinical tests . These are physical movements or postures. These can help determine if there are other types of injuries. No special equipment is needed to perform these tests. The doctor will ask you to lie down, sit, or stand in a specific position, and then move your knee.

In addition, imaging tests may be used to take pictures of the knee joint and surrounding tissues. For example:

• Knee X-rays
• Ultrasound
• Magnetic Resonance Imaging (MRI)

Knee Sprain Grades

Doctors classify knee sprains based on the extent of damage to the ligaments:

• Grade 1 Sprain (Mild): There is a very slight stretching or tearing of the ligaments. Or there may be just a stretching without any tearing. This is the mildest level.
• Grade 2 Sprain - Moderate: The ligaments are partially torn, but not completely torn. This is a moderate level.
• Grade 3 Sprain - Severe: The ligaments are completely torn, meaning they are broken. These Grade 3 sprains are commonly called Ligament Tears . This is a severe level.

What are the treatments for knee sprains?

Most of the time, symptoms of a sprained knee can be managed at home. However, it is important to see a doctor first to properly diagnose the injury and make sure there is no other damage to the inside of the knee.

The most common treatment for knee sprains is the RICE method :

• R - Rest: Avoid the activity that caused the injury. Try not to use the knee until it heals.
• I - Ice: Apply an ice pack to your knee for about 15 minutes several times a day. Wrap the ice pack in a thin cloth or towel, and do not let it touch your skin directly.
• C - Compression: Wrap an elastic bandage around your knee to help reduce swelling. Your doctor will show you how to do this safely.
• E - Elevation: Keep your knees above heart level as much as possible. Keep your legs on pillows when lying down.

Painkillers from the group of NSAIDs (Non-Steroidal Anti-Inflammatory Drugs), such as Aspirin or Ibuprofen, to reduce pain and swelling.Yes, you can use paracetamol (Acetaminophen). Talk to a doctor before taking these types of painkillers for more than 10 days.

You may need to wear a brace to support your knee and help keep it in place. You may also need to use crutches until your knee heals. Your doctor may also recommend physical therapy to help prevent knee stiffness and improve your range of motion.

Do knee sprains require surgery?

Surgery is rarely necessary after a sprained knee. However, if you have a severe sprain or other injuries, such as a bone fracture, surgery may be necessary.

How soon will I feel better after starting treatment?

Once you start treatment for a sprained knee, you will gradually start to feel better. It may take several weeks for the symptoms to subside.

Ask your doctor how much use you can do while your knee is healing. Do not start using your knee again until your doctor tells you to, even if you feel better. If you put pressure on your knee before the ligaments have fully healed, you are more likely to get injured again or make the original sprain worse.

What can you expect if you sprain your knee?

Knee sprains are usually temporary injuries . Most sprains do not affect your ability to play or stay active after your doctor says it's safe to play or train.

However, if you sprain your knee once, you may be slightly more likely to injure it again in the future (especially if you have had a moderate or severe sprain). Ask your doctor what you can do to reduce your risk of future sprains.

How long does it take for a knee sprain to heal?

It usually takes at least a few weeks for a sprained knee to heal. More serious sprains can take up to several months. Your doctor will talk to you about this.

Ask your doctor what activities and movements are safe to do while you recover. He or she will also tell you when it is safe to resume strenuous physical activity using your knee.

How do you prevent a sprained knee?

There may be no way to completely prevent a sprained knee, especially if you're an athlete. But there are ways to reduce your risk. Be aware of these things when playing sports or other physical activities:

• Wear proper safety equipment (including properly fitting shoes).
• If your knee hurts, whether during or after physical activity, don't "play through the pain."
• After strenuous activityGive your knee a rest and time to heal.
• Do warm-up and stretching exercises before playing sports or exercising.
• Do cool-down and stretching exercises after physical activity.

Follow these general safety tips to reduce the risk of injury:

• Keep your home and workplace tidy and free of unnecessary items that could trip you or others.
• Always use properly designed tools or equipment to reach things that are high up in your home. Never climb on chairs, tables, or counters.
• If you have difficulty walking or are at high risk of falling, use crutches or a walker.

When should I see a doctor?

If you have been in an accident and have symptoms of a sprained knee, see a doctor. If your symptoms don't improve (or if they get worse) after a few days of treatment, talk to your doctor.

When should I go to the Emergency Department (ETU) ?

If you have any of these symptoms, go to an emergency room immediately:

• Very severe pain.
• The swelling is increasing.
• Discoloration - It looks like the area around the knee is turning blue/purple.
• If you cannot move your knee or leg at all (inability to move the joint).
• If you heard or felt a sound like "knock knock" or "pop" from your knee.

What should I ask my doctor?

• Do I have a sprained knee or another injury?
• What grade of sprain is this?
• What kind of treatment do I need?
• How long will it take to heal?
• When can I start training or playing again?
• What types of exercise are safe to do while recovering?

What is the difference between a knee sprain and a ligament tear?

Knee sprains and knee ligament tears are similar injuries. The difference is how badly your ligaments are stretched or damaged.

Grade 1 and 2 knee sprains mean your ligaments are stretched or partially torn, but not completely torn. A grade 3 knee sprain is a complete tear, meaning the injury has stretched your ligament so far that it is almost torn.

So, grade 3 knee sprains and ligament tears are the same injury. These can include:

• MCL tears
• LCL tears
• ACL tears
• PCL tears

If you have pain, swelling, or can't move your knee, see a doctor. He or she can diagnose the injury and recommend the most appropriate treatment.

Finally, things to remember (Take-Home Message)

Knee sprains are painful, and it can be scary to know you've injured your knee. It's a common (and frustrating) risk for anyone who plays sports or is physically active. The good news is that most knee sprains heal with rest and home treatment.

If you have symptoms like knee pain and swelling – especially if you sprained your knee or hit something – don’t ignore it. See a doctor to diagnose the injury. That way, you can figure out what’s wrong, how long it will take to heal, and when it’s safe to start training and playing again. Take care of your knees!
