Understanding Knee and Leg Injuries in Auto Collisions and Your Recovery Options

November 08, 2025

Even a seemingly minor car accident can cause devastating lower-body injuries that affect mobility, independence, and overall quality of life. The knees and legs absorb much of the crash’s force, leading to fractures, torn ligaments, or chronic pain that may take years to heal. According to the National Highway Traffic Safety Administration (NHTSA), more than 2.4 million people sustained injuries in vehicle crashes nationwide in 2023, with lower-extremity trauma being among the most frequent and costly categories.

For Missouri victims, timely medical treatment and trusted legal guidance from Harper, Evans, Hilbrenner & Netemeyer can make all the difference in securing both physical recovery and fair financial compensation.

Key Takeaways

  • Knee and leg injuries are among the most common results of car accidents.
  • Dashboard or footwell impact often causes ligament tears, fractures, and soft-tissue damage.
  • Early medical care and thorough documentation are crucial for a successful recovery and strong legal claims.
  • Compensation often depends on the documentation of long-term treatment and loss.
  • Missouri personal injury lawyers can help victims achieve a full and fair recovery.

Common Impact Points for Lower Body Injuries

During a crash, the lower body absorbs a significant amount of energy from the vehicle’s frame and cabin. The result is often sudden trauma to joints, muscles, and bones.

How These Injuries Occur

  • Dashboard collisions: Knees strike the dashboard, tearing the posterior cruciate ligament (PCL) or fracturing the kneecap.
  • Footwell intrusion: Collapsed pedals or floor panels crush the tibia or fibula.
  • Side impacts: Lateral forces strain the medial collateral ligament (MCL) or dislocate the hip.

The American Academy of Orthopaedic Surgeons (AAOS) explains that dashboard impacts are a leading cause of PCL injuries, with side impacts frequently causing multiple ligament tears. High-speed collisions often result in compound fractures and complex joint damage.

Summary: Recognizing the mechanics behind these injuries enables medical professionals and attorneys to establish a clear link to crash dynamics, thereby strengthening compensation claims.

Types of Knee and Leg Injuries

Car crash victims often face a combination of ligament, bone, and muscle damage. Each injury type requires unique treatment and recovery approaches.

Soft-Tissue Injuries

  • Ligament tears, including those of the ACL, PCL, MCL, and LCL, reduce stability and mobility.
  • Meniscus tears: Damaged cartilage limits flexibility and causes chronic pain.
  • Tendon injuries: Torn quadriceps or patellar tendons often need surgical repair.

Bone and Structural Injuries

  • Fractures: Breaks to the femur, tibia, or fibula are common in severe impacts.
  • Crush injuries: Result from high-force compression, sometimes leading to nerve loss.
  • Compartment syndrome: A dangerous buildup of pressure that can threaten limb function.

National Library of Medicine reports that untreated leg injuries can lead to permanent complications, reinforcing the need for immediate care and accurate diagnosis.

Summary: Proper medical imaging, diagnosis, and follow-up are essential for ensuring long-term health and supporting fair settlement evaluations.

Surgical vs. Non-Surgical Treatments

Treatment varies by injury severity and patient health. Doctors typically start with conservative care but may recommend surgery for severe trauma.

Non-Surgical Options

  • Rest, ice, compression, and elevation (RICE) to reduce swelling.
  • Bracing or casting for stable fractures and partial ligament tears.
  • Physical therapy to rebuild strength and coordination.

Surgical Treatments

  • Arthroscopy: A minimally invasive procedure for ligament and cartilage repair.
  • Open reduction and internal fixation (ORIF): Realignment of broken bones using plates or screws.
  • External fixation: Temporary stabilization for severe or compound fractures.

The American Academy of Orthopaedic Surgeons confirms that surgical reconstruction may take months of rehabilitation. A documented treatment plan helps attorneys estimate both current and future medical expenses.

Summary: Accurate documentation of every phase of care, from diagnosis to rehabilitation, strengthens legal claims and improves medical outcomes.

Recovery Time and Rehabilitation

Healing from knee and leg injuries takes time and discipline. Each patient’s recovery timeline depends on the complexity of the injury and the chosen treatment method.

Recovery Phases

  • Soft-tissue injuries: 6–12 weeks for sprains; up to 6 months for ligament repairs.
  • Fractures: 10–16 weeks for bone healing; a year for full functional recovery.
  • Post-surgical rehab: Gradual increase in weight-bearing, followed by strength and gait training.

The Centers for Disease Control and Prevention (CDC) notes that regular follow-up care reduces long-term disability. Missing therapy sessions can delay progress and negatively impact settlement value.

Summary: Consistent rehabilitation not only promotes physical recovery but also demonstrates your commitment to healing, strengthening your legal position.

Impact on Work and Mobility

Lower-body injuries frequently limit independence and job performance. Workers in physical jobs may face lost wages and reduced earning capacity.

Challenges Victims Often Face

  • Difficulty standing or walking for long periods.
  • Chronic pain or weakness is limiting daily activities.
  • Psychological stress from decreased independence.

According to the Agency for Healthcare Research and Quality (AHRQ), emergency visits for crash-related injuries average $750 per patient, contributing to an $80 billion national burden annually. The cost of surgery and therapy further underscores the importance of securing comprehensive compensation.

Summary: Beyond medical bills, knee and leg injuries can cause financial, emotional, and professional setbacks that require full legal consideration.

Including Leg Injuries in Your Claim

Missouri law allows injured parties to seek damages for medical costs, lost wages, and pain and suffering. Success depends on early documentation and timely legal action.

Evidence That Supports Your Claim

  • Detailed medical records and imaging results.
  • Physician and therapist reports documenting progress.
  • Proof of lost income and workplace adjustments.
  • Testimony from medical or occupational experts.

Under Missouri Statute Section 516.120, victims generally have five years to file a personal injury claim. Visit our personal injury page to understand your rights and deadlines.

Summary: Comprehensive documentation of both medical and financial losses ensures a more substantial, evidence-based claim.

Real Case Examples from Missouri Clients

Example 1: Dashboard Collision

A Columbia driver suffered a PCL tear and a kneecap fracture after a front-end crash. After surgery and therapy, they returned to work in eight months. The settlement covered medical expenses, rehabilitation, and lost wages.

Example 2: Side-Impact Tibia Fracture

A Missouri passenger sustained a tibial plateau fracture that required surgical fixation. With proper legal representation, the client secured compensation covering all medical costs and future therapy.

Note: Results vary. Prior outcomes do not guarantee future success.

Frequently Asked Questions

  1. How soon should I see a doctor after my knee or leg starts hurting?
    Immediately. Early medical intervention can prevent further damage and support your claim.
  2. Can I claim compensation if I share partial fault?
    Yes. Under Missouri’s comparative fault rule, you may still recover damages based on your share of responsibility.
  3. How long does recovery take after knee surgery?
    Recovery typically takes 6–9 months, depending on the severity of the condition and the individual’s commitment to therapy.
  4. What if the insurance company offers a quick payout?
    Avoid settling early. Quick offers rarely account for future medical expenses or rehabilitation costs.
  5. Will my claim go to court?
    Most claims are settled out of court through negotiation, but experienced attorneys are prepared to go to trial if necessary.
