Knee Pain: Causes, Treatment, and Prevention

Knee pain is one of the most common musculoskeletal complaints, affecting individuals of all ages. The knee joint is essential for daily activities such as walking, running, sitting, and standing. When knee pain arises, it can significantly affect mobility and overall quality of life. Whether caused by an injury, overuse, arthritis, or another condition, understanding the underlying cause of knee pain is crucial for effective treatment. At Shanti Hospital, our orthopedic specialists are here to provide personalized care to help you manage and relieve knee pain, restore function, and get back to your normal activities.

Common Causes of Knee Pain

1. Osteoarthritis
   Osteoarthritis (OA) is the most common form of arthritis and a leading cause of knee pain, particularly in older adults. OA occurs when the cartilage in the knee joint wears down over time, leading to pain, stiffness, and swelling. It often affects the knee’s weight-bearing surfaces, limiting movement and causing discomfort.
2. Rheumatoid Arthritis
   Rheumatoid arthritis (RA) is an autoimmune disorder that causes chronic inflammation in the joints, including the knees. RA typically affects both knees simultaneously and can lead to severe pain, swelling, and eventual joint damage if left untreated.
3. Ligament Injuries
   The knee is supported by several important ligaments, including the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL). Injuries to these ligaments, such as sprains or tears, often occur during sports or high-impact activities. An ACL tear, for example, is a common knee injury that can cause significant pain, swelling, and instability.
4. Meniscus Tears
   The meniscus is a piece of cartilage that provides cushioning between the thigh bone (femur) and shin bone (tibia). Meniscus tears can occur from sudden twisting movements, often during sports or physical activities, leading to pain, swelling, and difficulty moving the knee.
5. Patellar Tendonitis
   Patellar tendonitis, also known as jumper’s knee, involves inflammation of the tendon connecting the kneecap (patella) to the shin bone. It’s often caused by overuse, especially in athletes or individuals who perform repetitive jumping or squatting movements.
6. Bursitis
   Bursitis is the inflammation of the bursae, small fluid-filled sacs that cushion the knee joint. It commonly occurs due to repetitive motion or prolonged pressure on the knee, leading to pain, swelling, and tenderness. Prepatellar bursitis, also known as “housemaid’s knee,” is a common type.
7. Patellofemoral Pain Syndrome (Runner’s Knee)
   Patellofemoral pain syndrome, or “runner’s knee,” occurs when the cartilage under the kneecap becomes irritated. It often results from overuse, poor alignment, or muscle imbalances. Pain is typically felt around or behind the kneecap, particularly when going up or down stairs, squatting, or sitting for extended periods.
8. Iliotibial Band Syndrome (IT Band Syndrome)
   The iliotibial band (IT band) is a thick band of tissue that runs along the outside of the thigh and knee. IT band syndrome occurs when this band becomes tight or inflamed, often causing pain on the outside of the knee, particularly during activities like running or cycling.
9. Knee Fractures
   Knee fractures can occur due to direct trauma, falls, or high-impact injuries. Fractures can involve the bones of the knee joint, including the femur, tibia, or patella, and may cause severe pain, swelling, and difficulty moving the knee.
10. Osgood-Schlatter Disease
    Osgood-Schlatter disease is a condition that affects adolescents, particularly those involved in sports. It occurs when the growth plate at the top of the tibia becomes inflamed due to repeated stress, leading to pain and swelling just below the knee.

Symptoms of Knee Pain

Knee pain can present in a variety of ways, depending on the cause. Common symptoms include:

• Pain or tenderness in the knee joint, particularly with movement or pressure
• Swelling, warmth, or redness around the knee
• Stiffness or difficulty straightening or bending the knee
• Clicking, popping, or grinding sensations when moving the knee
• Instability or weakness in the knee, especially with weight-bearing activities
• A visible deformity, particularly in the case of fractures or dislocations

Diagnosis

To accurately diagnose the cause of your knee pain, our orthopedic specialists will perform a thorough examination and may utilize the following diagnostic tools:

• Physical Examination: A detailed assessment of your knee’s range of motion, strength, and areas of tenderness or instability.
• Imaging Tests: X-rays, MRIs, or CT scans can be used to identify fractures, cartilage damage, ligament tears, and other structural issues in the knee joint.
• Arthroscopy: In some cases, a minimally invasive procedure called arthroscopy may be used to examine the inside of the knee joint and assess damage to cartilage, ligaments, or menisci.
• Blood Tests: If an inflammatory condition, such as rheumatoid arthritis, is suspected, blood tests may be conducted to look for markers of inflammation.

Treatment Options

The treatment for knee pain depends on the underlying condition, severity, and your specific needs. Our goal is to provide effective, individualized care to alleviate pain and restore function. Treatment options may include:

1. Rest and Ice: Resting the knee and applying ice can reduce swelling and inflammation, especially after an injury or intense physical activity.
2. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) or acetaminophen can help manage pain and inflammation. In more severe cases, corticosteroid injections may be used to target inflammation in the knee joint.
3. Physical Therapy: A tailored physical therapy program can help strengthen the muscles around the knee, improve flexibility, and restore function. Therapy can also correct imbalances or alignment issues contributing to knee pain.
4. Bracing or Support: Using a knee brace or sleeve can provide support and stability to the knee, especially during physical activity or rehabilitation.
5. Assistive Devices: For those with mobility issues, a cane, crutches, or a walker may help reduce strain on the knee and improve walking ability.
6. Surgery: In cases of severe knee injuries or degenerative conditions, surgery may be necessary. Surgical options include:
   • Arthroscopic Surgery: A minimally invasive procedure to repair or remove damaged tissue, such as torn menisci or damaged cartilage.
   • Knee Replacement Surgery: In cases of advanced arthritis or joint damage, partial or total knee replacement may be recommended to replace the damaged joint with a prosthetic.
   • Ligament or Tendon Repair: Surgical repair of torn ligaments or tendons may be required for more severe injuries.

Preventing Knee Pain

While not all knee pain can be prevented, there are steps you can take to reduce your risk of developing knee problems:

• Exercise Regularly: Engage in low-impact activities such as swimming or cycling to keep the knee joint flexible and strong.
• Maintain a Healthy Weight: Excess body weight places added stress on the knee joints, increasing the risk of arthritis and other knee problems.
• Warm Up and Stretch: Before exercising, warm up your muscles and stretch to reduce the risk of strains and injuries.
• Wear Proper Footwear: Supportive shoes with proper arch support can help prevent knee pain caused by misalignment or poor posture.
• Avoid Overuse: If you’re involved in sports or physical activities, be sure to rest and avoid overloading the knee joint with repetitive movements.

When to See an Orthopedic Specialist

If your knee pain persists, worsens over time, or interferes with your daily activities, it’s important to consult an orthopedic specialist. Early diagnosis and intervention can help prevent further damage and ensure more effective treatment.
