Inner Knee Pain: Causes, Treatments, and Prevention

Knee pain can be a debilitating condition that affects people of all ages. One particular area that is commonly afflicted is the inside of the knee, also known as the medial knee or medial compartment. Inner knee pain can arise from various causes, including cartilage deterioration, sports injuries, trauma, and underlying knee conditions.

In this article, we will explore the common causes of inner knee pain, treatment options, and exercises that can help alleviate pain and prevent further injury.

Common Causes of Inner Knee Pain

  1. Osteoarthritis (OA): Osteoarthritis is a degenerative disease that leads to the breakdown of cartilage in the knee joint. As a result, the bones in the joint may grind against each other, causing inner knee pain. Activities such as climbing stairs or sitting down in a chair can exacerbate the pain associated with OA.

  2. Rheumatoid Arthritis (RA): Rheumatoid arthritis is an autoimmune disease that causes inflammation in the joints, including the knee. Individuals with RA often experience severe inner knee pain in the morning, which gradually decreases throughout the day.

  3. Medial Collateral Ligament (MCL) Injury: The MCL is a ligament that runs along the inner side of the knee joint, providing stability. An MCL injury occurs when this ligament is overstretched or torn, usually due to a forceful impact on the outer knee, such as during contact sports. Symptoms include swelling, instability while walking or standing, and a popping sound at the time of injury.

  4. Medial Meniscus Injury: The meniscus is a cartilage structure that acts as a cushion between the thigh and shin bones in the knee joint. Tears or damage to the medial meniscus can occur during sports or athletic activities that involve twisting or applying pressure to the knee. Symptoms may include stiffness, sharp pain when twisting the knee, and a sense of imbalance or locking.

  5. Pes Anserine Bursitis: Pes anserine bursitis is the inflammation of the bursa located between the medial collateral ligament and three tendons (sartorius, gracilis, and semitendinosus) in the knee. This condition can be caused by factors such as osteoarthritis, obesity, a medial meniscus tear, or abnormal knee and leg positioning. Pes anserine bursitis leads to swelling and pressure on the knee, resulting in inner knee pain.

  6. Medial Plica Irritation: Plica are small folds in the joint lining, and irritation of the medial plica can occur due to repetitive knee flexion. This irritation causes the folds to thicken and become trapped between the bones, leading to dull inner knee pain, locking knees, and occasionally a cracking sound.

  7. Knee Contusion: A knee contusion, or bruised knee bone, can occur from a direct blow to the knee, such as a fall or impact with a blunt object. Inner knee pain may arise depending on the location of the contusion. Symptoms include bruised skin, swelling, difficulty bending the knee, and stiffness.

Treating Inner Knee Pain

For minor knee pain, self-care measures can often alleviate symptoms. The RICE method (rest, ice, compression, and elevation) is commonly recommended. Avoid activities that cause pain, use crutches if necessary, apply ice for 20 minutes several times a day, compress the knee with an elastic bandage, and elevate the knee above heart level using pillows.

Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help reduce swelling and alleviate pain. However, if symptoms persist or worsen after three days, it is essential to consult a doctor for further evaluation.

In more severe cases or when home remedies fail, medical intervention may be necessary. Treatment options can include:

  1. Steroid Injections: Steroid injections are used to relieve inflammation and pain associated with conditions such as pes anserine bursitis.

  2. Physical Therapy: Physical therapy involves exercises, stretches, and sometimes ultrasound therapy to strengthen the knee and improve mobility. It can be beneficial for various knee injuries and conditions.

  3. Assistive Devices: Wearing a knee brace during activities can provide support and stability, particularly for individuals with osteoarthritis.

  4. Surgery: Arthroscopic knee surgery is often performed to repair meniscus tears or address other underlying issues. This minimally invasive procedure allows for a quicker recovery compared to traditional open surgery.

Exercises for Inner Knee Pain

While some causes of inner knee pain may not be preventable, strengthening the leg muscles, especially the quadriceps and hamstrings, can help treat and prevent knee injuries. Recommended exercises include:

  1. Straight Leg Lifts
  2. Leg Presses
  3. Mini Squats
  4. Stationary or Recumbent Biking
  5. Swimming
  6. Walking or Running on an Elliptical Machine
  7. Leg Extensions

It is crucial to incorporate stretching exercises for the quadriceps and hamstrings before and after any exercise routine. Stretching helps improve flexibility and reduce the risk of further knee injury. Consulting a physical therapist can provide personalized guidance on exercises based on individual needs and limitations.

The Bottom Line

Inner knee pain can stem from various causes, including cartilage deterioration, injuries, and underlying knee conditions. Early recognition and appropriate treatment are essential for managing pain and preventing further damage. Home remedies such as the RICE method, along with NSAIDs, can alleviate minor knee pain.

However, if symptoms persist or worsen, seeking medical attention is crucial. Treatment options may include steroid injections, physical therapy, assistive devices, or surgical intervention. Incorporating targeted exercises, particularly those focusing on quadriceps and hamstrings, can strengthen the knee and reduce the risk of injury. Remember to consult a healthcare professional for an accurate diagnosis and tailored treatment plan for your specific condition.
