Knee Injuries from Car Accidents – Torn ACLs, Fractures & More

Common Knee Injuries in Car Accidents

The force of impact during a car accident can directly affect the knee, causing severe injuries. Some of the most common knee injuries include:

Torn ACL (Anterior Cruciate Ligament) Injury

The ACL is one of the key ligaments that stabilize the knee. A torn ACL is often caused by sudden force or twisting motion during an accident. Symptoms include severe pain, swelling, and difficulty walking. According to the American Academy of Orthopaedic Surgeons (AAOS), ACL injuries may require surgery and 6 to 9 months of rehabilitation (AAOS).

Torn Meniscus

The meniscus is a piece of cartilage that cushions the knee joint. A torn meniscus can occur when the knee is twisted or bent forcefully during a collision. Symptoms include stiffness, swelling, and a locking sensation in the knee (Mayo Clinic).

Knee Fractures

A fractured kneecap (patella fracture) or a tibial plateau fracture can occur when the knee hits the dashboard during a crash. These fractures can be severe and may require surgery. The Cleveland Clinic notes that fractures can take several months to heal, and some patients may need physical therapy for complete recovery (Cleveland Clinic).

PCL (Posterior Cruciate Ligament) Injury

PCL injuries, often called “dashboard knee injuries,” happen when the knee is forced backward against the dashboard. This type of injury causes swelling, knee instability, and difficulty bending the leg (Johns Hopkins Medicine).

Dislocated Knee

A knee dislocation is a severe injury where the knee bones are entirely out of place. This condition can damage blood vessels and nerves, leading to complications. Emergency treatment is necessary to prevent long-term disability (American Academy of Orthopaedic Surgeons).

Knee Contusions & Soft Tissue Damage

Soft tissue injuries such as bruises, sprains, and ligament strains are common in minor car accidents. While they may heal with rest and physical therapy, some cases can result in chronic pain and mobility issues (Harvard Health Publishing).

Causes of Knee Injuries in Car Accidents

• Impact with the Dashboard – Direct force on the knees during a collision.
• Twisting Motion – Abrupt twisting of the knee joint from sudden stops or turns.
• Side-Impact Crashes – T-bone accidents can force the knee into the car door or center console.
• Rear-End Collisions – The force of being hit from behind can cause sudden knee hyperextension.

Treatment Options for Knee Injuries

• Rest & Ice – Reduces swelling and promotes healing.
• Physical Therapy – Strengthens the knee and restores mobility.
• Bracing & Immobilization – Prevents further injury while healing.
• Surgery (If Necessary) – Torn ligaments and fractures may require surgical repair.

Legal Options for Knee Injury Victims

If another driver’s negligence caused your knee injury, you may be entitled to compensation for:

• Medical Expenses – Surgery, therapy, and medication costs.
• Lost Wages – If your injury prevents you from working.
• Pain & Suffering – Compensation for physical and emotional distress.
• Future Medical Costs – Ongoing treatments or rehabilitation.

Missouri follows a comparative fault rule, meaning even if you were partially at fault, you can still recover damages (Missouri Revised Statutes, Section 537.765).

What to Do After a Car Accident Knee Injury

• Seek Medical Treatment Immediately – Delayed care can worsen injuries.
• Document Your Injuries – Keep medical records, X-rays, and prescriptions.
• Report the Accident – File a police report and gather witness statements.
• Consult a Personal Injury Attorney – A lawyer can help maximize your compensation.
