If you’re reading this, you are probably wondering if you’ve sprained the outside of your knee. Maybe your knee buckled outward or twisted awkwardly when you turned around suddenly. A joint sprain or overstretch can injure ligaments, muscles, and tendons (or more than one)/overstretch; however, ligament injuries often happen first. The ligament connecting the outside of your knee is called the Lateral Collateral Ligament (LCL). Think of the LCL as your knee’s high-tension outer tether and anchor. A structure this strong needs a sudden varus force, an extreme outward blow, that exceeds what the ligament can physically endure. Whether it’s a sharp change of direction on the field, an awkward twist with your foot in one position, a painful hyperextension, or a direct hit to the inside of your knee, the tissue reaches its breaking point, and it causes lateral knee pain.

The good news is the LCL is injured in only about 2% of knee injuries. The bad news is, it usually isn’t injured in isolation. Other knee ligaments, meniscus, and muscles are usually injured as well.

The lateral collateral ligament (LCL)

Imagine a strong, slender bundle of ropes on the outer side of your knee. This is your lateral collateral ligament (LCL). It is a strong bundle of fibres that connects your thigh bone (femur) to your lower leg bone (fibula). The LCL stabilizes and protects your knee joint from too much side-to-side movement.

Other ligaments in the knee

Besides the LCL, your knee has more main ligaments. Opposite to the LCL is the medial collateral ligament (MCL). Deep in the center of the knee joint are two cruciate (cross) ligaments: the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). They stabilize forward and backward movement of your knee, and together, all these ligaments anchor your knee joint.

Muscles Around the Knee

Around your knee, there are many incredibly strong and important muscles. The most well-known are the quadriceps at the front of your thigh and the hamstrings at the back. The hamstrings split into two, with one part connecting to the inside of the knee and one part connecting to the outside. Together with a smaller muscle called the popliteus, they help control rotation and forward movement of your knee. Think of them as both the engine and brakes for your knee. The lateral hamstring (also called the biceps femoris), popliteus, and LCL all intertwine and attach to the bones on the outside of the knee. Usually, when one is injured, the others are also injured.

Menisci: The Knee’s Shock Absorbers

Inside your knee joint, there are two menisci. They are C-shaped, cartilage-like structures that pad the inside of your knee joint and help to absorb shock. They also make the gliding action within the knee easier.

The knee and hip connection

Most of the thigh muscles connect the knee and hip. Your ITB (iliotibial band) is a long, tight band of tissue that connects the outside of your hip bone to the outside of your knee bones. Even though you might focus your attention on your lateral (outside) knee joint pain, remember that it always affects your hip movement as well.

The knee’s side protector

Imagine the lateral collateral ligament (LCL) as a guardian positioned on the outside part of your knee. Its role is to prevent the knee from buckling sideways. The LCL also acts like a messenger. By keeping the knee stable, it helps your body to sense your knee’s position in space. This is called proprioception, and it’s like a sixth sense for your knee. You can move without thinking about every step.

The team dynamics

The LCL doesn’t operate solo; it’s part of a team. Alongside companions like the medial collateral ligament (MCL) and the cruciate ligaments (ACL and PCL), they collaborate effectively as a team. This teamwork gives your knee the best stability. You need knee stability to squat, run, jump, or hike up a mountain. You also need balance and coordination to dance,  leap, turn, and partake in sport.  The team of ligaments in your knee allows you to maintain balance and stability, giving you confidence when you move.

The side swipe

Whether your knee was struck from the inside, twisted over a planted foot, or overstretched, the damage goes deeper than a simple ligament sprain. At a cellular level, your body immediately launches a repair project to heal that torn ligament.

The clean-up crew: inflammatory phase

When a ligament is sprained, it looks like a rope fraying. On a microscopic level, you will see micro-tears in the tissue. Blood vessels surrounding the ligament break and bleed. This forms small blood clots that bridge the two ends of the tear. Inflammatory cells rush in to clear out dead cells. The increase in chemical and cellular activity causes swelling, throbbing, heat, and pain.

The weak scaffolding: proliferative phase

Next, specialized repair cells (fibroblasts) move in to build new tissue. They quickly lay down Type III collagen, a weak and messy form of scar tissue. As time goes by, your knee is less sore and swollen, but the new tissue is very fragile. At this stage your knee is very vulnerable to re-injury.

The reinforcement and remodeling phase

In this final stage, your body systematically breaks down the weak Type III collagen and replaces it with dense, strong Type I collagen. This forms a healthy ligament. These collagen fibers cannot align on their own; they organize purely in response to tension. This is where the importance of physiotherapy comes in: progressive, guided exercise forces these chaotic fibers to line up straight along the ligament’s pull line. Ultimately transforming fragile scar tissue back into a high-tension stabilizer.

• Direct Blow to the Inner Knee

  : A strong impact, to the inside of the knee leads to an increased stretch of the outside of the knee. In football, a common reason for LCL injuries is a hit to the knee during tackles leading to a notable number of knee ligament injuries in the sport.

• Twisting Movements: Twisting your knee, with your foot planted in one place can easily injure the lateral side of the knee and LCL. This frequently occurs in sports when athletes pivot, turn or change direction quickly.
• Hyperextension: Over-straightening your leg into an extreme range can also injure the LCL (as well as other ligaments). This is like bending a ruler backward until it starts to strain. An example of this when a gymnast or acrobat needs to land with a hyperextended knee. 
• Landing after a jump: Landing on an unstable surface or even falling over after you land, can easily put too much strain on the outside of your knee. This leads to a strain injury of the lateral knee.

Mild LCL Injury (Grade I)

A mild LCL injury, classified as Grade I, may cause pain and tenderness on the outer part of your knee. The swelling is usually minimal. When you bend your knee sideways (such as during a Varus stress test), you may experience some discomfort. However, your knee should not feel unstable or loose. This type of LCL injury typically indicates that your ligament is strained rather than torn.

Moderate LCL Injury (Grade II)

On the other hand, a moderate LCL injury, categorized as Grade II, can be more painful. You are likely to experience increased soreness and pain on the outer part of your knee along with swelling. During the Varus stress test, there will be more discomfort. Your knee may feel slightly unstable. This suggests that your ligament is partially torn, which is greater than just a strain.

Severe LCL Injury (Grade III)

In a severe LCL injury, the ligament is fully torn. Surprisingly, there are instances where the pain may not be as intense, as a grade II injury. However, the issues are more severe. You may still experience pain and sensitivity on the part of your knee along with swelling. When you check your knee by bending it you will notice a looseness indicating that the ligament is not providing the necessary support. This kind of injury can lead to a greater sense of instability in your knee.

Other Injuries that come with LCL Injuries

When your LCL is injured it’s not unusual for other parts of your knee to suffer damage well. Additional ligaments, in your knee, such as the Anterior Cruciate Ligament (ACL) or Posterior Cruciate Ligament (PCL), or the Posterolateral Compartment (PLC) a group of tissue structures at the back of your knee may also be affected. In some cases the injury might be severe enough to cause a dislocation where the bones are displaced. Occasionally there could also be damage to the menisci, which act as shock absorbers inside your knee. Keep an eye out for injuries to the back or side of your thigh, like hamstring or Iliotibial Band Syndrome.

We are confident to diagnose your lateral collateral ligament (LCL) sprain as skilled physiotherapists. We make our priority to locate the exact reason for your knee pain and from there formulate a treatment plan that will suit you lifestyle. With the right knowledge about the anatomy of your knee, we can look at the bigger picture and see if you have injured any surrounding muscles or joints.

To start off with the diagnostic procedure of a LCL sprain, we get a complete history of your injury and symptoms. After that, we do a thorough physical examination of your knee:

• Palpation: We feel for tenderness, swelling, increased warmth, pain response or muscle spasm.
• Range of Motion: It is important to measure how far you can bend and straighten your knee before you feel stiffness or pain.
• Muscle Strength Testing: With any ligament injury, you’ll always have accompanying muscle pain or injury. By testing the strength of muscles like your quadriceps and hamstrings, we’ll be able to identify any muscle dysfunction and measure your knee stability.
• Special Tests: Stretching and stressing the ligaments around your knee help to identify which ligaments were injured.

Ligaments cannot be seen on an x-ray, so it won’t be the first choice of investigation to use. However, x-rays can show the bone structure of your knee joint and can help to rule out any fractures.

Your physiotherapist can refer you to get x-rays taken if necessary.

Diagnostic ultrasound can be used to show the presence of a tear in the ligament. It will also be used to assess the surrounding soft tissues and amount of swelling and fluid.

If you need an ultrasound, your physio will refer you.

An MRI is the gold standard for seeing the full extent of a knee injury. It will be able to show us bones, ligaments, nerves, tendons, cartilage and swelling. However, it is an expensive option and you need to be referred by a specialist doctor to get this test.

Your physiotherapist can refer you to the appropriate specialist if you need to get a scan like this.

Delayed healing and chronic inflammation:

Your LCL may not have fully healed, leading to continued discomfort. Because your injury does not heal properly and can keep getting injured, this may lead to chronic inflammation. This inflammation will result in the formation of scar tissue can limit movement and cause discomfort.

Complications and Muscle Imbalances:

Other injuries or conditions, like Baker’s Cyst or Arthritis, might have developed. This may develop because the supporting muscles of your shoulder were not strong enough to stabilize the knee, which will put you at risk of developing other painful conditions of the knee.

Improper Treatment and Underlying Conditions:

The initial treatment might not have addressed the root cause or severity of the injury. Not only may improper treatment affect the recovery of your shoulder, there may also be factors that you may have not considered such as Diabetes, Osteoporosis or Rheumatoid Arthritis.

Not using protective gear properly

It is not uncommon for people to place themselves in a sling for either too short or too long of a time. This may lead to inadequate healing or cause the shoulder to become weak and dependent on the sling for their pain.

Treating the wrong problem or not completing treatment at all

Not getting a proper diagnosis from the start is another issue. It wastes valuable time and delays appropriate treatment. Failure to identify the root cause of your heel pain leads to ineffective treatment. Patients often try out various forms of treatment but fail to complete them. Committing to a consistent and comprehensive treatment plan under professional guidance is essential for effective recovery.

Rest and pain medication alone won’t solve the problem

Relying on medication can mask the pain without addressing the root cause of the problem. Finding the balance between resting and safe movements is key to recovery. People tend to think that they can stretch the pain away, but usually it makes the problem worse. It’s important to follow a guided exercise program with a combination of different types of exercises for different muscle groups. Resting too much or too little can be detrimental. Too much rest leads to weakness and stiffness and deconditioning. Too little rest simply prolongs the inflammation.

As experienced physiotherapists, we understand that a lateral collateral ligament injury is painful and frustrating to recover from. We want to assure you that together, we can create a treatment plan to guide you through recovery. It will include a combination of techniques designed to reduce your pain and inflammation, and to improve your shoulder mobility and strength.

• Manual therapy: Hands-on techniques, like soft tissue mobilization and joint mobilization, to decrease your pain and increase your range of motion of your knee.
• Therapeutic exercises: We’ll work together on targeted exercises to strengthen and stretch the muscles around your knee. This usually includes working on the muscles of the front and the back of your knee.
• Activity modification: Initially, we guide you to modify your daily activities and exercise to minimize stress on your knee.
• Pain management and Education: Giving you the information you need to understand your pain, helps with long-term pain relief. We can advise you on different pain-relief strategies that are both safe and effective.
• Other effective modalities: We will also use pain management techniques such as Dry Needling and Electrotherapy that has been proven to manage pain. Strapping can also be used to protect the injured area so that the joint may heal properly.

The goal is to help you get back to your daily life and exercise routine as soon as possible, while minimizing the chances of hurting your ligament, or other important structures in and around your knee.

Acute Phase (Days 1-7):

• Pain and Swelling: Right after the injury, you’ll probably feel quite a bit of pain on the outer side of your knee, and it might swell up too.
• Relative Rest and Protection: It’s important to give your knee a break during this time. You might need to use a brace to keep your knee stable and take the pressure off the LCL. This will protect the ligament while preventing the rest of your muscles from getting weaker.
• Ice and Elevation: Applying ice and keeping your knee raised can help reduce swelling and pain. This will provide a safe way to reduce your pain without any unwanted side effects such as impaired healing.

Subacute Phase (Weeks 1-6):

• Reduced Pain: As time goes on, the pain should start to get better, and the swelling will go down too.
• Gentle Movement: You can start doing some gentle exercises to get your knee moving again, but it’s important not to push it too hard. We can guide you on what’s safe to do.
• Strength and Stability: As your knee starts to feel better, you’ll work on building up the strength in your leg muscles and improving the stability of your knee.

Remodeling Phase (Weeks 6-12+):

• Continued Improvement: By now, your knee should be feeling a lot better, but you might still be working on getting back to 100%.
• Advanced Exercises: You’ll be doing more advanced exercises to make sure your knee is strong and stable enough to handle your usual activities. This can include sports or getting through your work day without feelings of instability or pain.
• Gradual Return to Activity: Depending on how severe your injury was, you might be able to start getting back to sports or other activities around this time. It’s important to listen to your body and not rush things.

• Doctor

  : Your doctor can assist you with a diagnosis and a prescription for pain medication if necessary. Medication is a handy tool in your recovery process, but it should be used with guidance and in combination with rehabilitation. The use of cortisone is not recommended.

• Biokineticist: Rehabilitation can also be guided by a biokineticist, especially when you need help to return to your exercise routine or sport.
• Chiropractor: Trying to ‘click’ your knee joint ‘back into place’ after an injury like this is not recommended. It can flare-up the inflammation process or worsen the ligament tear.
• Orthotist: An orthotist can recommend and prescribe a knee brace and crutches according to the severity of your injury. A brace can help with healing, especially in the acute phase of your injury. However, there should be a management plan in place, to make sure that you move and use your knee independently again.

Surgery may be necessary for an LCL injury if the ligament is completely torn, the knee is highly unstable or if other knee structures are also affected. Before opting for surgery, we will assess the extent of the injury to the knee’s functionality, as well as your activity level and objectives.

It’s important to understand that surgery marks the beginning of your knee’s healing process. The real work starts after the surgery as the body needs time to heal and regain the strength it needs to adapt to the new changes. Rehabilitation after surgery plays a role in reducing swelling and pain, restoring knee movement, improving muscle strength and getting you back to your previous activities.

There are different surgical techniques that may be chosen. The first involves a reconstruction using a graft to replace the torn ligament while another technique such as repair entails stitching together the torn ends. Regardless of the approach taken, post-operative rehabilitation is integral for a full recovery, by aiding you in regaining the stability and function of your knee.

• Iliotibial band syndrome: Pain at the outside of your knee, thigh or even hip. Typically caused by overuse and very common in runners. 
• Meniscus tear (lateral meniscus): This is an injury of the extra cartilage layer inside the knee joint. It often causes a clicking or locking sensation in your knee. Caused by a twist injury of your knee. .
• Cruciate ligament injury (ACL or PCL): These ligaments are found inside the knee joint. It protects the tibia from sliding forward or backward on the femur. Very common to injure it when you have to change direction or stop suddenly.
• Lateral hamstring tendinopathy: The outside part of the hamstring tendon attaches onto the knee. Close to the LCL. Tendon pain often feels worse when you exercise and afterwards as you cool down. Severe stiffness of your knee the next morning.

“We can handle it” vs “Our knowledgable expert physiotherapists are well versed, confident, and experienced in their approach to diagnosing your…”

We follow a structured plan to diagnose, classify the severity, and determine the hierarchy of priority that your knee needs. We stress, screen and scan all the possibilities that could be causing your pain. Identify any other injuries to surrounding structures. If there is an injury to the ligaments, meniscus, muscles or nerve, or cartilage we will find it.

We understand the physiological healing stages you’ll go through, and custom-fit your treatment program. By knowing the extent of the tissue damage we can guide you through a structured program to recover faster and safely return to the things you love doing. That’s why our physiotherapists are the best at diagnosing this type of problem.

Why is it crucial to get/understand a diagnosis? Does it mean anything? Or is it a death sentence? or will you treat it differently if you know what you’re dealing with?

Muscles cannot be seen on an x-ray, so it will not be effective to diagnose a muscle spasm. X-rays will however show the integrity and alignment of joints in your spine. This will enable us to see if something is wrong with the structure of the bones in your spine or if there is a loss of disc space.

What are you looking for on an X-ray? Cortical stress lines, Displacement measurements, What Classification is done via X-ray?

Your physiotherapist can refer you to get x-rays taken if necessary.

Diagnostic ultrasound can be used to show the presence of a muscle tear (muscle strains), inflammation, swelling or simply increased contraction of a muscle (muscle spasms).

If you need an ultrasound, your physio will refer you.

An MRI scan can image all of the structures in your lower back, including soft tissue, discs, nerves and bones. However, for a muscle spasm an image like this is unnecessary and very expensive. If your physiotherapist suspects anything more than just a muscle spasm, you will be referred to the right specialist.

Is an MRI necessary for this diagnosis – if not when could it become a necessity?

Please inspire confidence in your ability to test, identify, diagnose and treat/ deal with this.

Example:

Our priority is to determine the extent of the damage to your piriformis muscle. Then, we test the structures surrounding your hip and lower back to clear the nerve pathway and resolve the sciatic nerve pain. Avoiding nerve compression is crucial to prevent relapse and restore the sciatic nerve’s regular sliding. We must protect the muscle from overworking by differing forces away from the piriformis muscle, strengthen the surrounding muscles, correct the compensation, and retrain the correct firing pattern. This allows time for the piriformis muscle to adapt and heal. Our practitioners bring on a change and monitor the results until it’s working, and then we magnify the effects to get even better outcomes.
