What Is a Bone Bruise? - Signs, Recovery, and Care
Written by Medicover Team and Medically Reviewed by Dr Praveen Sodavarapu , Orthopedics
A bone bruise is an injury that affects the trabecular (spongy) tissue inside the bone, causing bleeding and swelling within the bone structure. Unlike a fracture, where the bone cracks or breaks, a bone bruise does not involve a visible break but can still be quite painful and require significant healing time.
This type of injury typically results from a direct blow or trauma, such as a fall, sports injury, or car accident. The impact leads to microfractures in the trabecular bone, which may not be visible on standard X-rays. Bone bruises often require rest and monitoring, and in some cases, MRI scans are needed to confirm the diagnosis and rule out more serious damage.
What are the Types of Bone Bruises?
Bone bruises, also known as bone contusions, can be classified into three main types based on the location and nature of the injury within the bone structure:
- Subperiosteal Bone Bruise: This occurs beneath the periosteum, the outer layer covering the bone. It typically results from a direct impact that causes blood to collect under the periosteum, leading to localized pain and swelling.
- Interosseous Bone Bruise: Found within the trabecular (spongy) bone, this type of bruise is often the result of compressive forces, such as those sustained during high-impact activities or accidents. It causes bleeding and edema inside the bone.
- Subchondral Bone Bruise: This occurs just below the cartilage surface of a joint and is often associated with joint injuries or ligament damage. Subchondral bone contusions are commonly seen in the knee, ankle, or hip and may contribute to joint stiffness and pain.
Each type of bone contusion varies in severity and healing time.
What is the Most Common Bone Bruise?
Bone bruises often occur after trauma, such as falls, sports injuries, or collisions. The knee is the most commonly affected joint, especially in cases of ACL tears, where studies show up to 80% also have a bone bruise.
Bone bruises can occur in any part of the body, but are more commonly seen in the long bones of the legs, such as:
- Femur (thigh bone)
- Tibia (shin bone)
- Fibula (calf bone)
These bones are more vulnerable due to their weight-bearing role and exposure to high-impact forces during physical activity.
What are the Symptoms and Warning Signs of a Bone Bruise?
The symptoms of a bone bruise (or bone contusion) can vary depending on the severity and location of the injury, but they typically include the following:
- Pain at the Injury Site: Persistent and localized pain that may worsen with pressure or movement.
- Swelling and Tenderness: The affected area may become swollen, warm, and tender to the touch due to internal bleeding and inflammation.
- Stiffness and Reduced Range of Motion: Particularly in joints, bone bruises can lead to stiffness and difficulty moving the area comfortably.
- Discoloration or Bruising of the Skin: Although the damage is internal, some bone bruises may also cause visible skin bruising nearby.
- Lingering Pain After an Injury: If pain lasts for more than a few days after a trauma or injury and does not respond well to basic treatment, it could be a sign of a bone contusion.
Warning Signs to Watch For
- Pain that does not improve with rest and over-the-counter medications
- Swelling that increases instead of decreases
- Difficulty bearing weight or using the affected limb
- Joint instability or locking, especially in the knees or ankles
If these symptoms persist or worsen, it's essential to seek medical evaluation. In some cases, what appears to be a simple bruise may mask a more serious condition like a fracture or ligament injury.
What are the Causes and Risk Factors of Bone Bruises?
Understanding the causes of bone bruises is essential for prevention and management. Below are some common causes:
Common Causes of Bone Bruises
- Sports Injuries: Contact sports, such as football, basketball, and hockey, can lead to bone contusions from sudden falls, collisions, or overuse.
- Falls and Accidents: Slips, trips, or car accidents can result in a direct blow to a bone, causing bruising without an actual break.
- Joint Trauma: Injuries that involve joint impact (e.g., knee, ankle, or wrist) can cause subchondral bone bruises, often associated with ligament damage.
- Repeated Stress or Overuse: In athletes or physically active individuals, repeated stress on a bone without proper rest can lead to microtrauma, which can eventually result in bone bruises.
Risk Factors
- High-Impact Activities: Athletes and individuals involved in high-intensity sports are at greater risk.
- Previous Injuries: A history of joint or bone injuries may weaken bone structure, making it more prone to bruising.
- Low Bone Density: Conditions like osteopenia or osteoporosis may increase vulnerability to bone contusions even with minor trauma.
- Age and Physical Condition: Older adults and individuals with poor muscle support or balance are more likely to suffer from falls, leading to bone bruises.
Understanding these causes and risk factors helps prevent bone bruises and ensures timely diagnosis and care when they occur.

Get Second OpinionHow is a Bone Bruise Diagnosed?
Diagnosing a bone bruise involves a careful clinical evaluation, especially since its symptoms can resemble those of more severe injuries like fractures or ligament tears. An early and accurate diagnosis helps prevent complications and ensures the proper treatment approach is taken.
Diagnostic Procedures for Bone Bruise:
- Physical Examination: The doctor assesses the injured area for swelling, tenderness, and range of motion. A detailed history of the trauma is also recorded.
- X-rays: While X-rays cannot detect bone bruises directly, they are helpful to rule out fractures or dislocations.
- MRI (Magnetic Resonance Imaging): MRI is the most reliable imaging test for identifying bone bruises. It provides clear images of soft tissue and the internal structure of bones, revealing bleeding and edema in the trabecular bone.
- Ultrasound: This may be used to assess joint effusions or soft tissue swelling, though it's less specific than MRI.
Unlike fractures, bone contusions may not show up on standard imaging in the early stages, which is why MRI is often preferred for a conclusive diagnosis. In some instances, repeat imaging may be needed if symptoms persist.
What are the Treatment Options for Bone Bruises?
Treating a bone bruise requires a combination of rest, symptom management, and sometimes physical therapy, depending on the location and severity of the injury. While not as severe as fractures, bone bruises can take several weeks to heal fully.
Common Bone Bruise Treatments
- Rest and Activity Modification: Limit activities that put pressure on the injured area. For leg injuries, using crutches may help reduce strain on the bone.
- Cold Compresses: Apply ice packs for 15 & 20 minutes during the first 48 & 72 hours to reduce swelling and relieve pain.
- Pain Management: Medications such as paracetamol or NSAIDs (e.g., ibuprofen) can help alleviate pain and inflammation.
- Compression and Elevation: Wrapping the area with a bandage and keeping it raised helps control swelling and speeds up recovery.
- Physical Therapy: After the initial pain subsides, gentle exercises can be initiated to restore strength, movement, and flexibility, particularly for joint-related injuries.
- Surgical Intervention (Rare): Surgery is not usually needed unless there are other injuries like torn ligaments or cartilage damage along with the bone bruising.
When to See a Doctor for a Bone Bruise?
While many bone bruises heal with conservative care, it's essential to know when to seek medical attention. Ignoring persistent symptoms can delay recovery and increase the risk of long-term complications.
See a Doctor If You Experience
- Pain lasting more than 5-7 days after the injury, especially if it doesn't improve with rest or over-the-counter pain relief
- Swelling that worsens or does not subside after the initial injury phase
- Inability to bear weight or move the joint normally
- Visible bruising that spreads or deepens in color
- Stiffness or limited range of motion that interferes with daily activities
High-Risk Groups That Need Prompt Medical Attention
- Athletes and active individuals returning to high-impact sports
- Elderly adults, who may have weakened bones and are more prone to complications
- People with osteoporosis or low bone density
- Children where joint or bone pain may signal more serious underlying conditions
Doctors treat symptoms and check for related injuries like ligament or cartilage damage. Early consultation ensures proper diagnosis and faster recovery.

What is the Recovery Process After Bone Bruise Treatment?
Recovering from a bone bruise (bone contusion) is a gradual process that depends on the severity and location of the injury. Most individuals can expect improvement within a few weeks, but deep or joint-related bone bruises may take longer to heal.
Post-Treatment Expectations:
- Follow-up Schedule: Patients are typically reviewed every 2-4 weeks to monitor their progress in healing. Follow-up imaging (usually MRI) may be advised in severe or persistent cases.
- Lifestyle Recommendations:
- Avoid high-impact activities until cleared by your doctor.
- Use protective gear if returning to sports.
- Maintain a healthy weight to reduce stress on bones and joints.
- Dietary Tips: A bone-healthy diet rich in calcium, vitamin D, magnesium, and lean protein can support bone regeneration. Hydration also plays a role in tissue recovery.
- Physical Therapy: Gradual reintroduction of movement and strengthening exercises under the guidance of a physiotherapist can help restore joint function and prevent stiffness.
With proper care, most bone contusion heal without complications. However, joint-related bone contusions may take several months to heal and require continued monitoring to prevent chronic joint issues or cartilage damage.
What Precautions Can Help Prevent Bone Bruises?
Preventing bone bruises means protecting your body from injuries and keeping your bones healthy through good habits and regular care.
Prevention Tips
- Wear appropriate protective gear during sports or physical activity.
- Warm up and stretch properly before exercising.
- Use proper footwear to avoid falls or ankle injuries.
- Maintain bone strength through a balanced diet and regular weight-bearing exercises.
- Avoid overtraining and take rest days to prevent stress-related injuries.
- Regular Screenings: Individuals with low bone density, a history of fractures, or joint instability should undergo periodic evaluations to detect early signs of bone weakening.
Potential Complications of Untreated
- Chronic pain and joint stiffness
