A knee strain means you’ve damaged one ligament surrounding your knee joint. Four main ligaments are responsible for their role in the stabilization of your knee. Additionally, several lesser ligaments may cause pain following an injury. Strains and strains can be confused. A sprain can be described as an injury to a ligament.

Ligaments are the structures that join two bones. They play a crucial role in providing joint stability while simultaneously allowing joints to move. For knee joints, ligaments enable the joint of your knee to bend back and forth, but they also control excessive movement.

The collateral ligaments in the knee stop excessive side-to-side motion, whereas the cruciate ligaments play a role in forward/backward stability.

Types of Sprains

It is believed that there are four main ligaments within the knee. Each is essential in keeping the knee in place and allowing a person to enjoy the full range of motion.

The two cruciate ligaments govern the back-and-forth movement of the knee. The two collateral ligaments regulate the sideways motion of the knee.

The type of knee strain the person is suffering is contingent on the ligament is injured:

Anterior Cruciate Ligament

Healthcare professionals generally identify this joint as the ACL. It’s located on the inside of the knee joint.

The two ligaments of the cruciate control the movement back and forth within the knee. They create an ‘X’ shape when they are joined. The anterior ligament of the cruciate is located that is in the front.

Posterior Cruciate Ligament

PCL is the rear counterpart of the Anterior Cruciate ligament, also known as the ligament. The PCL regulates the forward motion of the tibia or the shin bone.

Medial Collateral Ligament

This ligament is referred to as the MCL. It’s the ligament that provides stability to the knee’s inner femur.

Collateral ligaments can be found on both edges of your knee. The medial collateral ligament lies located inside the knee.

Lateral collateral ligament

It is the ligament that provides stability to the outside of the knee. It is known as the collateral ligament lateral, or LCL, located outside the knee.

The Knee Sprain Symptoms

Knee Sprain

The most frequent indications of a knee sprain are swelling and pain. Typically, when someone has injured their knee, causing injury to ligaments, they’ll notice immediate signs. Sometimes, these symptoms will worsen in an initial period of 48 hours and then slowly diminish, dependent on the extent and severity of the injury.

The most frequently reported signs of a knee sprain to consist of the following:

  • Knee discomfort
  • Swelling of the knee
  • Joint stiffness
  • Instability/giving-out/buckling

What Causes a Knee Sprain?

A knee sprain can be described as an injury to ligaments that connect the joints of the knees. Ligaments are strong tissue bands that connect bones and aid in stabilizing joints. The sprain happens when those ligaments get stretched out or torn due to excessive force. The knee sprain can be caused by several reasons, including:

  1. Trauma: A blow directly at the knee due to a fall or collision in sports could result in a knee injury such as a sprain.
  2. Overuse: Stress that is repeated to the knee joint, for example, running or jumping, can cause an injury such as an injury called a sprain.
  3. The knee can be turned or twisted by twisting. A knee joint can be susceptible to injury when it’s bent or turned awkwardly, for example, when placing the foot and then turning it to alter direction during sports.
  4. Instability or weakness of the knee joint: If the muscles supporting the knee have weak muscles, or the joint fluctuates, it’s more susceptible to sprains.
  5. Lack of flexibility The muscles and tendons surrounding the knee are stiff and rigid. They could be more susceptible to injury if extended to a greater extent than their range of movement.


Assessment of someone who injured their knee requires testing various ligaments that can be the reason for damage because of the knee injury. Specific movements may use in tests to isolate the multiple ligaments to aid your physician in identifying the root of your discomfort.

Sometimes, specialized tests like X-rays or magnetic resonance imaging (MRI) can be conducted in case of a suspicion of more severe injuries or when the diagnosis is unclear.

The idea of a “knee sprain” is not an extremely useful way to diagnose for two reasons:

  • It doesn’t tell you which ligament is affected since various ligaments are treated differently. For instance, anterior cruciate ligament (ACL) injuries typically require surgery to repair. On the other hand, MCL (MCL) damage rarely requires surgery.
  • It isn’t able to tell how much the ligament is damaged. This information is so essential because minor injuries typically require only minor treatment. For more severe injuries, they might need more extensive treatment or rehabilitation and may require surgery.

Yet many patients are told that they have an injury to their knee. If you’re diagnosed with an injury to your knee, try to learn more. Determine the ligaments affected, and you’ll be able to understand the possible treatment options and rehabilitation options required.


Based on the severity of the injury, The home remedy may be all an individual will require to heal his knee effectively. If, however, the knee is not healing within several weeks, it is recommended to visit the doctor.

The use of painkillers such as Acetaminophen and ibuprofen can help reduce the pain and decrease inflammation.

If the sprain is very severe, the injury may require medical attention.

One should seek treatment at the earliest time possible in the event of these symptoms:

  • A loud popping sound.
  • The knee is released in the event of injury.
  • The inability should move to the knee.
  • Limping occurs.
  • Swelling is seen at the injury site.
  • The joint appears to be deformed.
  • Severe pain.

Home Treatment

In the home, one can use this RICE method:

  • Rest: Give your knee time to get better.
  • Ice Packs of Ice areas over the area for twenty minutes. Repeat this, then repeat the process four to eight times per day trusted Source.
  • Compression: Compression socks are used to reduce swelling.
  • The knee can elevate and also aid in reducing swelling.

Physical therapy can also treat knee injuries and strengthen the muscles.

Medical treatment

Knee Sprain treatment

Surgery might be an alternative in certain instances like Grade III sprains.

It is usually done by reconnecting the ligament that has been damaged by replacing it with a piece of healthy tendon from another area or body.

ACLs that are repaired typically fail with time, and the surgeon might make a replacement graft out of the tendon.


While people might not be capable of preventing knee ligament sprains entirely, they can limit the possibility of having a sprain.

When playing sports, athletes must warm up before practice or competing. It is also recommended to put on appropriate shoes and build leg strength through exercises for the legs and knees.

When is the Best Time to Visit a Doctor?

If a knee injury causes more than a slight swelling and pain or for an extended period, it is essential to consult a physician.

Consult a physician If any of the following symptoms appear:

  • Inability to support the weight of the knee.
  • An explosion sound that occurs when the injury is being treated.
  • Serious knee swelling.
  • Inability to completely extend the knee or bend the knee.
  • A fever.


The knee is vital for movement and mobility, so it is crucial to have sprains checked by a doctor.

A knee ligament sprain could result from injuries or tears in the ligaments.

Individuals must make the right choices to let the knee injury fully heal before returning to regular activities.
