Car crashes can cause significant knee injuries.

At Sam Aguiar Injury Lawyers, we take the time to learn about your symptoms, the mechanism of the injury, the diagnosis methods, and the effective treatments to heal your injury.

Key Takeaways

Knee injuries from car accidents can result from direct impacts, unnatural positioning, or sudden forces, leading to ligament injuries, meniscal tears, and fractures.

Early recognition of symptoms such as pain, swelling, and instability is crucial for effective diagnosis and treatment of knee injuries, which may require imaging tests like MRI for accurate assessment.

Treatment options include conservative methods like the RICE protocol and physical therapy, as well as surgical interventions for severe cases; rehabilitation programs are essential for full recovery.



Common Knee Injuries From Car Accidents

The knee is particularly vulnerable to injury in the chaotic moments of a car accident. The most common knee injuries sustained in car accidents are typically caused by direct impact, sudden force, or unnatural positioning of the knee during the collision.

These traumatic injuries can range from mild to severe and often require medical intervention.

Ligament Injuries

Ligament injuries are among the most common knee injuries in car accidents. The Posterior Cruciate Ligament (PCL), often injured in “dashboard knee” scenarios, is damaged when the bent knee strikes the dashboard.

Similarly, the Medial Collateral Ligament (MCL) can be torn or stretched when the side of the knee is impacted during a collision.

Meniscal Tear

The meniscus, a cartilage cushions the knee joint, can tear due to forceful twisting or compression during an accident. A torn meniscus is among the most frequent knee injuries seen after car crashes.

Fractures

Fractures are another severe injury type, such as patella fractures caused by a direct blow to the kneecap from hitting the dashboard or steering column.

Tibial plateau fractures, resulting from high-energy trauma, are also common and often require surgical intervention to ensure proper alignment and healing.

Knee Dislocation and Soft Tissue Damage 

Severe trauma from a car accident can cause dislocation of the knee joint, where bones move out of their normal alignment.

Additionally, injuries to muscles, tendons, and other soft tissues around the knee are common and may result in pain, swelling, and reduced mobility.


Symptoms of Knee Injuries From Car Accidents

Recognizing the symptoms of knee injuries from car accidents is crucial for timely medical intervention. Common signs include pain, swelling, and instability.

Knee pain often comes with swelling, stiffness, and a feeling of warmth in the area. These symptoms can significantly impact daily activities and overall quality of life.

Injury may cause a popping or crunching sound during movement, which is often alarming and can indicate a significant structural issue within the knee.

Signs of inflammation, such as redness and increased temperature in the affected area, are also common and suggest the presence of an injury.

Weakness and instability in the knee are other indicators of injury. Severe knee injuries may cause an inability to fully extend or flex the knee, leading to significant mobility issues.

Early recognition of these symptoms is essential for preventing further damage and ensuring effective treatment.


Causes of Knee Injuries In Car Accidents

Understanding the causes of knee injuries in car accidents can provide insight into prevention and treatment.

The mechanisms of knee injuries typically involve direct impact, sudden force, or unnatural knee positioning during the collision. Here are the most common scenarios:

1. Dashboard Impact (“Dashboard Knee”)

A PCL injury often results from the knee striking the dashboard, leading to a forceful impact that can tear the ligament.

This type of injury is prevalent in front-end collisions where the knee collides with the car’s interior.

2. Hyperextension or Twisting

The sudden force of a crash can hyperextend or twist the knee unnaturally, leading to injuries such as torn ligaments and meniscus damage.

This can occur in various collisions, including side impacts and rollovers.

3. Side Impact

Collisions involving side impacts can lead to Lateral Collateral Ligament (LCL) injuries, which occur when the outer side of the knee is struck.

This can happen when the car is hit from the side, causing the knee to collide with the vehicle’s interior.

4. Compression and Crushing

The knee may be compressed or crushed under heavy objects, such as dashboard intrusion during a collision, leading to fractures in bones like the tibial plateau or patella.

High-energy trauma is a major contributor to fractures around the knee. 



Diagnosis Methods

Accurate diagnosis of knee injuries is essential for effective treatment.

A thorough physical examination helps assess the knee’s alignment, strength, and range of motion and identifies potential injuries.

This hands-on assessment is the first step in understanding the extent of the damage.

Imaging tests like X-ray and MRI are crucial for a detailed diagnosis.

X-rays are commonly used to visualize bone structure and help diagnose fractures and other knee-related issues.

Digital X-ray imaging captures high-quality images, making it easier to identify fractures and dislocations.

MRI is a noninvasive imaging technique that provides detailed pictures of knee structures without radiation exposure.

It can help identify issues like torn ligaments, meniscus damage, and cartilage injuries in the knee.

A specialized type of MRI known as an MR arthrogram involves injecting contrast material to enhance visualization of the knee.


Treatment Options

Depending on the severity of the injury, treatment approaches for knee injuries include conservative and surgical methods.

Choosing the proper treatment is essential to ensure a speedy and effective recovery.

Conservative Treatments

Initial treatment includes the RICE protocol, medications, and physical therapy to strengthen the knee and restore motion.

Surgical Treatments

Surgical options may be necessary for severe injuries that require surgery, with minimally invasive techniques preferred for quicker recovery. 

Conservative Treatments

Conservative treatments often serve as the first line of defense for many knee injuries.

The recommended protocol for treating initial knee injuries is the RICE protocol, which stands for Rest, Ice, Compression, and Elevation.

This approach helps reduce swelling and pain in the early stages of the injury.

Medications like anti-inflammatory drugs and pain relievers are commonly used in nonsurgical treatment to alleviate knee injury symptoms.

These medications can help manage pain and inflammation, making physical therapy more effective.

Physical therapy aims to strengthen the muscles surrounding the knee, enhancing stabilization and recovery.

Strengthening exercises are essential in a rehabilitation program. They help reduce knee joint stress by enhancing muscle support.

Stretching the strengthened muscles is crucial for restoring motion and preventing further injuries during recovery.

Surgical Treatments

When conservative treatments are insufficient, surgical intervention may be necessary to recover.

Common surgical methods for knee injuries include arthroscopic surgery for ACL tears and joint arthroscopies for other orthopedic conditions.

These minimally invasive techniques are preferred when suitable, as they typically result in shorter recovery times.

Persistent joint swelling, joint instability, and reduced range of motion despite strength training are indicators of potential surgery.

Open surgery is often required for fractures around the knee to ensure proper alignment and healing.

Consulting with an orthopedic surgeon is crucial to determine the best surgical approach for your injury.

Imaging tests are significant in planning the surgery and ensuring the best possible outcome.



Recovery and Rehabilitation

Recovery and rehabilitation are critical components of the healing process for knee injuries.

A comprehensive knee rehabilitation program typically lasts four to six weeks, depending on individual recovery needs.

Following the prescribed rehabilitation regimen is essential for a successful recovery.

Pre-surgery instructions, such as quitting smoking, can enhance recovery and reduce complications.

Adhering to these guidelines is important to ensure the best possible outcome from the surgery.

MRI scans can help monitor post-surgical recovery and evaluate the need for additional knee surgeries.

Regular follow-ups with your healthcare provider ensure that your recovery is on track and any complications are addressed promptly.


Importance of an MRI and Early Medical Intervention

An MRI (Magnetic Resonance Imaging) is critically important after a car accident to identify knee injuries for several reasons.

MRI scans are highly effective at identifying soft tissue injuries not visible on X-rays or CT scans, such as ligament tears, meniscal damage, tendon ruptures, and cartilage injuries.

Early detection of knee injuries ensures timely intervention, reducing the risk of chronic pain, joint instability, or long-term complications like arthritis.

Unlike other imaging techniques, MRIs produce high-resolution images of soft tissues, bones, and cartilage.

This allows for precise identification of the extent and location of injuries.

MRI findings guide treatment plans by confirming the need for physical therapy, surgical repair, or other interventions.

MRI scans document injuries sustained in the accident.

This evidence is crucial for insurance claims and legal cases, demonstrating the severity of the injury and ensuring fair compensation for medical expenses and recovery costs.

An MRI after a car accident is essential for diagnosing hidden knee injuries, enabling effective treatment, preventing long-term complications, and supporting legal claims.


The most common missed injuries without an MRI

Several specific knee injuries may be missed without an MRI because they are difficult to detect through physical examination or other imaging techniques, such as X-rays.

These injuries often involve soft tissues or subtle structural damage that require the detailed imaging capabilities of an MRI.

Meniscal Tears

These injuries involve soft tissues that are not visible on X-rays. Symptoms may overlap with other conditions, leading to misdiagnosis.

Meniscocapsular tears (Ramp Lesions) and meniscal root tears are examples of meniscal injuries that often require an MRI for accurate diagnosis.

Ligament Injuries

Partial ACL and posterior capsular ligament tears are challenging to detect clinically and may be missed without an MRI.

Medial Collateral Ligament (MCL) tears, especially low-grade or deep band injuries, may also be overlooked without MRI confirmation.

An ACL injury may complicate the diagnosis further.

Cartilage and Bone Injuries

Osteochondral injuries, such as tibial plateau fractures, may not be visible on X-rays but can be identified with MRI.

Complex injuries, involving multiple structures, often require an MRI for comprehensive diagnosis and treatment planning.



When to See an Orthopedic Surgeon

If rest, ice, compression, and elevation do not alleviate pain and swelling within two to three days, it’s advisable to consult an orthopedic surgeon.

Pain during rehabilitation exercises should not be ignored; consultation with a healthcare provider is advised if pain occurs.

An initial appointment with an orthopedic surgeon may not lead to surgery; conservative treatments like physical therapy are often explored first.

During the consultation, providing detailed information about your injury helps the surgeon better understand your condition.

To ensure safety and effectiveness, a healthcare professional should supervise an effective rehabilitation program after a knee injury.


Future Damages Claims For Knee Injuries In Car Accidents

Knee injuries from car accidents can have long-term consequences, making it essential to consider future damages claims.

Chronic pain is a common issue, often due to incomplete rehabilitation or premature return to activity.

Up to 25% of ACL reconstructions fail, leading to instability, recurrent tears, or the need for revision surgery.

Early-onset arthritis is another concern, with 20–30% of ACL reconstruction patients developing arthritis within a decade, especially if there is concurrent meniscus damage.

The psychological impact of knee injuries, such as anxiety, PTSD, or reduced physical activity due to fear of reinjury, can lead to weight gain and secondary health issues like diabetes.

Proper medical documentation and legal representation are crucial for securing fair compensation for these long-term effects.

Consulting with a legal expert can help you understand your rights and ensure you receive adequate compensation for medical expenses, rehabilitation costs, and any future complications resulting from the injury.


Preventing and Reducing Risk of Injuries.

Preventing knee injuries in car accidents involves a combination of proactive measures to improve vehicle safety, proper seating posture, and maintaining physical health.

Here are effective strategies:

1. Adjust Seating Position

Ensure your hips are at least as high as your knees, with a slight bend of 20–30 degrees in the knees.

This seating position reduces pressure on the lower back and provides better leg support.

Additionally, maintain a two-finger gap between the back of your knees and the seat to promote circulation and reduce the risk of dashboard impact injuries.

2. Use Safety Features

Properly secured seatbelts prevent your body from being thrown forward, reducing the risk of knee-versus-dashboard injuries.

Ensure airbags are functional, as they help absorb impact forces during collisions.

Advanced vehicle safety systems, such as Electronic Stability Control (ESC), Automatic Emergency Brakes (AEB), and Lane Departure Warning Systems (LDWS), can help prevent collisions.

3. Maintain Physical Health

Keeping a healthy weight reduces stress on your knees during everyday activities and minimizes injury severity in accidents.


Summary

Understanding knee injuries resulting from car accidents is crucial for effective treatment and prevention.

The common knee injuries include ligament injuries, meniscus tears, fractures, and dislocations, each requiring specific diagnostic and treatment approaches.

Recognizing symptoms early and seeking appropriate medical intervention can prevent long-term complications.

MRI scans are vital in diagnosing hidden injuries and guiding treatment plans.

Addressing knee injuries promptly ensures better recovery outcomes, whether through conservative treatments like the RICE protocol and physical therapy or surgical interventions.

Preventive measures, including proper seating, vehicle safety features, and maintaining physical health, can reduce the risk of traumatic injuries.

By staying informed and proactive, you can navigate the challenges of knee injuries and ensure a healthier future.
