Inner Knee Pain: Causes, Treatments, and Prevention

Knee pain can be a real burden, especially when it affects your ability to walk, exercise, or even stand comfortably. One type of knee pain that many people experience is inner knee pain. This refers to discomfort or aching on the inside of the knee, closest to the opposite leg. This type of pain can vary from a mild, nagging ache to sharp, debilitating pain.

This article will explore everything you need to know about inner knee pain: the common causes, symptoms, treatments, and prevention strategies. Whether you’re an athlete, an office worker, or just someone trying to maintain an active lifestyle, this article will provide you with practical advice.

What Is Inner Knee Pain?

Inner knee pain (also called medial knee pain) is discomfort that occurs on the inside part of the knee joint, closer to the opposite knee. The knee is a complex joint made up of bones, ligaments, tendons, and cartilage, and all of these structures work together to provide stability, strength, and flexibility. When something goes wrong with any of these components, you may experience pain that limits your mobility.

Pain in the inner knee can come on gradually due to overuse or suddenly from an injury. The causes can range from mild irritation to more serious conditions.

Common Causes of Inner Knee Pain

Several conditions can lead to pain on the inside of your knee. Below are some of the most common causes of inner knee pain, each of which affects the knee in different ways.

1. Medial Collateral Ligament (MCL) Injury

The medial collateral ligament (MCL) is located on the inner side of the knee and helps stabilize the joint. This ligament can be injured during activities that involve twisting or impact, such as soccer, basketball, or skiing.

Symptoms:

• Pain and tenderness along the inner side of the knee
• Swelling around the knee joint
• Instability or feeling that the knee may “give out” during movement

Treatment:

• Rest, ice, and compression are key to reducing swelling and pain in the early stages.
• Physical therapy may be needed to regain strength and stability in the knee.
• Severe cases may require a brace or, rarely, surgery to repair the ligament.

2. Osteoarthritis

Osteoarthritis is a common cause of inner knee pain, particularly in older adults. It occurs when the cartilage that cushions the knee joint wears away over time, leading to bone-on-bone contact and inflammation.

Symptoms:

• Aching pain, stiffness, and swelling, particularly after activity or in the morning
• A grinding or popping sensation when moving the knee
• Pain that worsens with weight-bearing activities like walking or climbing stairs

Treatment:

• Weight management and low-impact exercises like swimming or cycling can help reduce the load on the knee joint.
• Over-the-counter anti-inflammatory medications like ibuprofen can help manage pain and swelling.
• Physical therapy and, in some cases, corticosteroid injections can provide relief.
• In severe cases, a knee replacement may be recommended.

3. Pes Anserine Bursitis

The pes anserine bursa is a small fluid-filled sac located on the inner side of the knee, just below the joint. When this bursa becomes inflamed, often due to overuse or repetitive stress, it leads to a condition known as pes anserine bursitis.

Symptoms:

• Pain and tenderness on the inner side of the knee, just below the joint
• Swelling in the area
• Pain that worsens with physical activity, especially when climbing stairs or getting up from a seated position

Treatment:

• Rest and ice are crucial in reducing inflammation.
• Physical therapy to stretch and strengthen the surrounding muscles can help prevent future flare-ups.
• In some cases, corticosteroid injections may be recommended to reduce inflammation quickly.

4. Meniscus Tear

The medial meniscus is a C-shaped piece of cartilage that acts as a shock absorber between the thigh bone and the shin bone. A tear in the meniscus can occur during sports or from a sudden twisting motion. It’s also possible for the meniscus to degenerate and tear over time, especially in older adults.

Symptoms:

• Pain on the inner side of the knee, especially when twisting or turning
• Swelling and stiffness
• Difficulty fully bending or straightening the knee
• A clicking or locking sensation in the knee

Treatment:

• Mild tears may heal with rest, ice, and physical therapy.
• More severe tears may require arthroscopic surgery to repair or remove the damaged portion of the meniscus.

5. Patellofemoral Pain Syndrome (Runner’s Knee)

Patellofemoral pain syndrome (commonly known as runner’s knee) occurs when the cartilage under the kneecap becomes irritated, often due to overuse, improper alignment, or muscle imbalances. Although this condition typically causes pain in the front of the knee, it can also radiate to the inner knee.

Symptoms:

• A dull, aching pain around or behind the kneecap
• Pain that worsens with activities like running, jumping, or going up and down stairs
• A popping or grinding sensation when bending the knee

Treatment:

• Rest and modifying activity levels are key to preventing further irritation.
• Physical therapy to strengthen the quadriceps and improve patellar alignment can relieve symptoms.
• Custom orthotics or bracing may be recommended if improper alignment is contributing to the pain.

6. Knee Ligament Sprains or Strains

A sprain occurs when a ligament is overstretched or torn, while a strain involves injury to a muscle or tendon. The knee’s medial side is particularly susceptible to sprains and strains from sports injuries or sudden movements.

Symptoms:

• Pain, swelling, and bruising on the inside of the knee
• Difficulty moving the knee or putting weight on it
• Instability or weakness in the joint

Treatment:

• Immediate care typically involves the RICE method (rest, ice, compression, elevation).
• Depending on the severity, physical therapy may be required to restore strength and flexibility.
• More severe injuries may necessitate bracing or surgery to repair the damaged ligaments or tendons.

Treatment Options for Inner Knee Pain

Treating inner knee pain depends on the underlying cause, the severity of the injury, and your individual lifestyle needs. Below are the most common treatment approaches, ranging from conservative care to surgical options.

1. Rest and Activity Modification

In many cases, inner knee pain improves with rest and avoiding activities that aggravate the pain. If your pain is related to overuse, it may be helpful to take a break from high-impact exercises like running or jumping. You can also switch to low-impact activities like swimming or cycling until the pain subsides.

2. Ice and Heat Therapy

• Ice therapy: Applying ice to the knee for 15-20 minutes several times a day can help reduce inflammation and numb the pain, particularly after activity.
• Heat therapy: Once the acute inflammation has decreased, applying heat can relax tight muscles and improve blood flow to the area.

3. Physical Therapy

Working with a physical therapist can help you regain strength, flexibility, and stability in your knee. Physical therapy exercises often focus on stretching tight muscles and strengthening weak ones to relieve pressure on the knee joint. Common exercises include:

• Quad stretches and strengthening: To improve the balance between the quadriceps and hamstrings.
• Hip strengthening exercises: To address muscle imbalances that might contribute to knee pain.
• Balance and stability exercises: To improve overall knee function and prevent future injuries.

4. Medications

Over-the-counter medications like NSAIDs (nonsteroidal anti-inflammatory drugs) such as ibuprofen can help manage pain and reduce swelling. For more severe pain, your doctor may prescribe stronger medications or offer corticosteroid injections to reduce inflammation directly in the knee.

5. Bracing and Orthotics

A knee brace or orthotic inserts can provide extra support and stability, particularly if your pain is caused by improper alignment or instability in the joint. Wearing a brace during physical activities can help prevent further injury.

6. Injections

If your inner knee pain doesn’t improve with conservative treatments, your doctor may recommend injections. Common options include:

• Corticosteroid injections: To reduce inflammation and provide temporary pain relief.
• Hyaluronic acid injections: To lubricate the joint and improve movement in cases of osteoarthritis.

7. Surgery

Surgery is typically reserved for cases where non-surgical treatments have failed to relieve pain. Depending on the cause of your inner knee pain, surgical options may include:

• Arthroscopy: A minimally invasive procedure to repair damaged cartilage or remove loose fragments in the knee.
• Ligament repair: For severe ligament tears, such as an MCL tear, surgery may be needed to reconstruct the ligament.
• Knee replacement: For advanced osteoarthritis, a total or partial knee replacement may be necessary to relieve pain and restore function.

How to Prevent Inner Knee Pain?

While not all causes of knee pain can be prevented, there are steps you can take to reduce your risk of developing inner knee pain or worsening an existing condition. Here are some practical tips:

1. Strengthen the Muscles Around Your Knee

Strong muscles around the knee, particularly the quadriceps, hamstrings, and hip muscles, can provide extra support and reduce stress on the knee joint. Incorporate strength training exercises into your routine to build up these muscles and improve joint stability.

2. Maintain a Healthy Weight

Carrying extra weight can place added stress on your knee joints, increasing the risk of developing osteoarthritis and other knee conditions. Maintaining a healthy weight can help reduce the load on your knees and prevent pain.

3. Warm Up and Stretch

Before engaging in any physical activity, take the time to properly warm up your muscles and stretch. This can help improve flexibility and prevent muscle strains or ligament injuries.

4. Wear Proper Footwear

Wearing supportive shoes that provide proper arch support can help align your legs and knees, reducing the risk of knee pain. Avoid wearing shoes that are worn out or unsupportive, especially during physical activity.

When to See a Doctor?

While many cases of inner knee pain can be managed at home, there are times when it’s important to see a healthcare professional. Consider making an appointment if:

• Your pain persists for more than a few weeks, despite rest and home treatments.
