Under knee pain when walking often results from tendonitis, bursitis, ligament strain, or underlying joint issues that require targeted treatment.
Understanding Under Knee Pain When Walking
Pain beneath the knee during walking is a common complaint that can disrupt daily activities and reduce mobility. This discomfort can stem from various causes, ranging from minor injuries to chronic conditions affecting the structures around the knee joint. The area under the knee includes important tendons, ligaments, bursae, and cartilage that work together to support movement and absorb shock.
When pain occurs specifically during walking, it often signals stress or inflammation in one or more of these components. Pinpointing the exact cause is crucial for effective treatment and preventing further damage. The complexity of the knee’s anatomy means that under knee pain when walking can arise from multiple sources simultaneously.
Common Causes of Under Knee Pain When Walking
Tendonitis
Tendonitis refers to inflammation of the tendons connecting muscles to bones around the knee. The patellar tendon, which runs from the kneecap to the shinbone just below the knee, is a frequent site of injury. Overuse or repetitive strain—common in runners, cyclists, and athletes—can cause patellar tendonitis (also known as jumper’s knee). This condition typically produces sharp pain under the kneecap during activity.
Bursitis
Bursae are small fluid-filled sacs that cushion bones and tendons near joints. Inflammation of these sacs—bursitis—can cause tenderness and swelling beneath the knee. Prepatellar bursitis (in front of the kneecap) or infrapatellar bursitis (below the kneecap) often leads to discomfort when walking or kneeling.
Ligament Strain or Injury
Ligaments stabilize the knee by connecting bones together. A strain or partial tear in ligaments such as the posterior cruciate ligament (PCL) can cause deep pain under the knee during movement. Although less common than anterior cruciate ligament (ACL) injuries, PCL damage frequently results from sudden trauma or hyperextension.
Meniscus Tears
The menisci are two crescent-shaped cartilage pads cushioning and stabilizing the joint between thighbone and shinbone. Tears in the meniscus—especially in its posterior horn near the back of the knee—can manifest as aching or sharp pain beneath the knee during walking. Meniscus injuries often occur due to twisting motions or degeneration over time.
Osteoarthritis
Degenerative changes in cartilage with osteoarthritis can affect areas below the kneecap causing persistent aching pain that worsens with activity like walking. Cartilage breakdown reduces shock absorption leading to bone-on-bone contact and inflammation within the joint.
Symptoms That Accompany Under Knee Pain When Walking
Pain under the knee while walking may present alongside several other symptoms depending on its cause:
- Swelling: Visible puffiness around or beneath the knee.
- Stiffness: Difficulty bending or straightening the leg fully.
- Warmth and Redness: Signs of inflammation in bursitis or infection.
- Popping or Clicking: Sensations linked to meniscus tears.
- Instability: Feeling like your knee might give out due to ligament injury.
- Tenderness: Soreness when pressing on specific spots below the kneecap.
Recognizing these accompanying symptoms helps narrow down potential causes for targeted treatment.
Diagnosing Under Knee Pain When Walking
Doctors typically start diagnosis with a thorough history and physical examination focusing on:
- The exact location of pain under the knee.
- The activities that trigger or worsen symptoms.
- The presence of swelling, tenderness, or instability during movement tests.
Imaging techniques play a crucial role in confirming diagnosis:
| Imaging Type | Main Use | Description |
|---|---|---|
| X-ray | Bony abnormalities & arthritis | Reveals bone fractures, joint space narrowing indicating osteoarthritis. |
| MRI (Magnetic Resonance Imaging) | Tissue damage & soft tissue evaluation | Visualizes ligaments, tendons, menisci tears, and inflammation. |
| Ultrasound | Tendon & bursa assessment | Screens for tendonitis and bursitis by showing soft tissue swelling. |
Laboratory tests may be ordered if infection or systemic inflammatory diseases are suspected.
Treatment Options for Under Knee Pain When Walking
Effective treatment depends on identifying and addressing underlying causes. Here’s an overview of common approaches:
Rest and Activity Modification
Reducing activities that exacerbate pain allows inflamed tissues time to heal. Avoiding high-impact exercises like running temporarily can decrease stress on tendons and ligaments.
Icing and Compression
Applying ice packs for 15-20 minutes several times daily reduces swelling and numbs painful areas beneath the knee. Compression wraps help limit fluid buildup around inflamed tissues.
Physical Therapy Exercises
Targeted exercises strengthen muscles supporting the knee joint while improving flexibility. Quadriceps strengthening reduces patellar tendon strain; hamstring stretches alleviate tightness contributing to joint stress.
Pain Relievers and Anti-inflammatory Medications
Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen ease pain by reducing inflammation in tendons or bursae.
Corticosteroid Injections
In cases where conservative treatments fail, injections into inflamed bursae or around tendons provide powerful localized relief lasting weeks to months.
Surgical Intervention
Surgery may be necessary for severe meniscus tears not responding to therapy or chronic ligament instability impacting walking ability.
Lifestyle Adjustments To Prevent Recurrence of Under Knee Pain When Walking
Preventing future episodes involves maintaining joint health through smart choices:
- Mild Regular Exercise: Low-impact activities like swimming improve muscle tone without stressing knees.
- Adequate Warm-up: Preparing muscles before exercise reduces injury risk by increasing blood flow.
- Shoe Selection: Supportive footwear with proper cushioning absorbs shocks during walking.
- Weight Management: Excess body weight increases pressure on knees accelerating wear-and-tear.
- Avoid Prolonged Kneeling: Minimizing pressure on infrapatellar bursa prevents bursitis flare-ups.
Implementing these habits protects knees long-term while enhancing overall mobility.
The Role of Biomechanics in Under Knee Pain When Walking
Abnormal gait patterns contribute significantly to under knee pain when walking by altering force distribution across joints:
- Knee Valgus (Knock-knee): This inward collapse increases stress on medial tendons below knees.
- Knee Varus (Bowleg): This outward alignment overloads lateral structures causing imbalances.
- Poor Foot Mechanics:
A biomechanical assessment by specialists helps identify faulty movement patterns so corrective measures such as orthotics can be prescribed.
The Impact of Age on Under Knee Pain When Walking
Aging naturally brings wear-and-tear changes affecting structures below knees:
- Tendon Degeneration: Tendons lose elasticity making them prone to microtears causing chronic pain during movement.
- Bursa Thickening:bursae may become less flexible leading to repeated inflammation episodes with activity stress.
Aging also increases risk for osteoarthritis which commonly presents as persistent aching below knees exacerbated by walking.
Elderly individuals should emphasize gentle strengthening exercises combined with adequate rest periods.
