Knee pain after a car accident shouldn’t be ignored. Even a seemingly minor collision can place significant stress on the knee joint, ligaments, cartilage, tendons, and surrounding soft tissues, resulting in injuries that may not become apparent for hours or even days.
According to the Cleveland Clinic, the knee is the largest joint in the body. It absorbs significant force during everyday activities like walking, running, and climbing stairs, making it especially vulnerable to injury during a traumatic event such as a car accident.
That complexity also means it’s not always obvious which part of the knee has been injured after an accident without a thorough evaluation. Prompt diagnosis can help identify the source of your pain and ensure you receive the right treatment before symptoms become more severe.
Knee injuries are common after car accidents because the force of a collision can place significant stress on the knee joint and surrounding soft tissues.
Whether you’re involved in a rear-end collision, side-impact crash, or head-on accident, the sudden force can stretch or tear ligaments, tendons, and cartilage or damage the bones that make up the knee joint.
One of the most common injury mechanisms occurs when the knee strikes the dashboard during a collision. The impact can injure the kneecap, damage cartilage, or tear important stabilizing ligaments, including the posterior cruciate ligament (PCL).
Slip-and-fall accidents can also result in knee injuries, particularly when the knee twists during a fall or absorbs the force of landing directly on the joint.
If you’re experiencing persistent knee pain after an auto accident, it’s important to seek medical evaluation promptly.
For patients injured in a Florida auto accident, receiving an initial medical evaluation within 14 days may also help preserve eligibility for Personal Injury Protection (PIP) benefits.
Depending on how the accident occurred, knee injuries can also happen alongside hip injuries or ankle and foot injuries. A comprehensive evaluation can help identify all injuries and guide the most appropriate treatment plan.
Knee injuries after an accident can make it difficult to stand, walk, climb stairs, or perform other everyday activities.
While some symptoms appear immediately after an accident, others may develop gradually as swelling and inflammation increase.
Common symptoms of a knee injury include:
The symptoms you experience often depend on the specific type of knee injury you’ve sustained.
Knee injuries can range from mild sprains to more serious damage involving the ligaments, cartilage, tendons, or bones that make up the knee joint.
At Complete Care, we evaluate the extent of your injury and develop a treatment plan based on your diagnosis, symptoms, and recovery goals.
The knee relies on four primary ligaments to provide stability: the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL).
During a car accident, these ligaments can become stretched or torn when the knee twists suddenly or absorbs a direct impact, such as striking the dashboard.
Symptoms of a ligament injury may include:
The meniscus is a piece of cartilage that cushions and stabilizes the knee joint.
A forceful twist during a car accident or slip-and-fall accident can tear the meniscus, resulting in pain, swelling, stiffness, or a catching or locking sensation when moving the knee.
Symptoms may include:
The force of a collision can seriously injure the kneecap (patella) or the bones that form the knee joint. These injuries commonly occur when the knee strikes the dashboard or another hard surface during a crash.
Symptoms may include:
Depending on the force of the accident, you may also experience:
Knee injuries can also occur alongside other lower-extremity injuries. If you’re experiencing pain in your hips, ankles, or feet in addition to your knee, your provider may also evaluate those areas to ensure all injuries are identified and treated.
Accurately diagnosing a knee injury is the first step toward effective treatment.
Because many knee injuries produce similar symptoms, a thorough evaluation can help determine which structures have been affected and whether additional testing is needed.
Your provider will begin by discussing your accident, symptoms, medical history, and the onset of your pain. They will also perform a physical examination to evaluate your range of motion, stability, strength, swelling, and areas of tenderness.
If a more serious injury is suspected, advanced diagnostic imaging may be recommended to confirm your diagnosis.
Depending on your symptoms and examination findings, your provider may recommend:
At Complete Care, our integrated approach allows providers to coordinate your evaluation and treatment, helping ensure your care plan is based on a clear and accurate diagnosis.
Treatment depends on the type and severity of your injury, as well as your symptoms and recovery goals.
Many knee injuries can be treated without surgery, especially when care begins soon after an accident.
Your provider will develop a personalized treatment plan designed to reduce pain, restore mobility, improve knee function, and help you safely return to your daily activities.
Many patients improve with conservative treatment, which may include:
Throughout your recovery, your care team will monitor your progress and adjust your treatment plan as needed.
Some knee injuries require surgical evaluation, particularly if there is significant structural damage or symptoms do not improve with conservative care.
Examples may include:
If surgery is appropriate, Complete Care coordinates referrals and ongoing care so your treatment remains seamless before and after your procedure.
Our spine and orthopedics team works closely with your other providers to support every stage of recovery.

Yes. It’s common for knee pain to develop hours or even days after an accident as inflammation increases and adrenaline wears off.
Even if your symptoms seem mild at first, it’s important to have your knee evaluated if you develop pain, swelling, stiffness, or difficulty walking.
Yes. A forceful twist or direct impact during a collision can tear the meniscus.
Symptoms may include pain, swelling, stiffness, and a locking or catching sensation when moving the knee.
A torn ligament may cause pain, swelling, instability, difficulty bearing weight, or the feeling that your knee is giving out.
A physical examination and diagnostic imaging are often needed to confirm the diagnosis.
Not every knee injury requires advanced imaging, but it may be recommended depending on your symptoms and physical examination.
Diagnostic imaging helps identify fractures, ligament injuries, meniscus tears, and other conditions that may not be apparent during an exam alone.
No. Complete Care does not treat broken bones. If you suspect a fracture of the kneecap or another bone in the knee joint, go to the nearest emergency room. If a fracture is identified during your evaluation at Complete Care, we will refer you to an appropriate specialist for treatment.
Many knee injuries can be treated without surgery through a combination of injury care, rehabilitation, activity modification, medications, and other conservative treatments.
If your injury is more severe or doesn’t improve with nonsurgical care, your provider may recommend a surgical evaluation.
You should seek medical evaluation as soon as possible if you develop knee pain, swelling, instability, difficulty bearing weight, reduced range of motion, or trouble walking after an auto accident or slip-and-fall accident.
Early diagnosis and treatment can help prevent complications and support a smoother recovery.
