Understanding Inner Knee Pain

Inner knee pain, medically referred to as medial knee pain, is a discomfort or pain located on the inside portion of the knee. This type of pain can arise from a variety of injuries or conditions and may range from a mild annoyance to a severe impediment.

The knee joint is a complex structure, consisting of bones, cartilage, ligaments, and tendons that work together to enable movement such as walking, running, and jumping. It is essential to understand the mechanics of the knee to identify the underlying causes of inner knee pain effectively.

12 Common Causes of Inner Knee Pain

1. Medial Collateral Ligament (MCL) Injury

The MCL is located on the inner side of the knee and helps stabilize the joint. It can be injured from a direct blow to the outer knee or from a force that pushes the knee inward, causing inner knee pain. MCL injuries are common in contact sports such as football or soccer.

2. Meniscus Tears

The meniscus is a C-shaped cartilage that cushions the knee joint. Tears can occur from sudden twisting or from degenerative changes with age. Inner knee pain, along with swelling and difficulty bending the knee, are typical symptoms of meniscus tears.

3. Osteoarthritis

Osteoarthritis is a degenerative joint disease that commonly affects the knee. Over time, the protective cartilage in the knee joint wears down, leading to inner knee pain, stiffness, swelling, and a reduced range of motion. Osteoarthritis is more prevalent in older individuals or those who have experienced knee injuries.

4. Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune condition that causes chronic inflammation in the joints, including the knee. The immune system mistakenly attacks the synovium, resulting in inner knee pain, swelling, stiffness, and joint deformity. Rheumatoid arthritis can affect individuals of all ages.

5. 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. Inflammation of this bursa, called pes anserine bursitis, can occur due to overuse, muscle imbalances, or obesity. Inner knee pain worsens with activities like running, walking up or down stairs, or prolonged sitting.

6. Medial Plica Syndrome

The medial plica is a fold of tissue within the knee joint that can become irritated or inflamed, resulting in inner knee pain. Repetitive knee movements, overuse, or injury may contribute to medial plica syndrome. Symptoms can include pain, clicking or snapping sensation, and swelling on the inner side of the knee.

7. Patellofemoral Pain Syndrome

Patellofemoral pain syndrome, commonly referred to as “runner’s knee,” is characterized by inner knee pain around or behind the kneecap (patella). It is often caused by overuse, muscle imbalances, poor alignment of the patella, or problems with the cartilage on the back of the kneecap. Activities involving bending and straightening the knee, such as running, squatting, or climbing stairs, may exacerbate the pain.

8. Iliotibial (IT) Band Syndrome

The iliotibial band is a thick band of connective tissue that runs along the outer side of the thigh, attaching to the outer aspect of the knee. Overuse or tightness of the IT band can cause friction and inflammation where it rubs against the inner knee, resulting in inner knee pain. IT band syndrome is common in runners and can be exacerbated by activities involving repetitive bending and extending of the knee.

9. Gout

Gout is a form of arthritis characterized by the buildup of uric acid crystals in the joints. When uric acid levels become elevated, crystals can form in the knee joint, leading to sudden and severe bouts of inner knee pain, swelling, redness, and warmth. Gout often affects the big toe joint but can also involve the knee joint.

10. Baker’s Cyst

A Baker’s cyst, or popliteal cyst, is a fluid-filled swelling that develops at the back of the knee joint. It can be caused by conditions such as meniscus tears, arthritis, or underlying knee joint inflammation. Baker’s cysts can cause discomfort or pain in the inner knee, especially when the knee is bent or fully extended.

11. Iliopsoas Tendinitis

The iliopsoas tendon, located at the front of the hip, passes over the front of the hip joint and inserts near the inner side of the upper tibia. Inflammation of this tendon, known as iliopsoas tendinitis, can cause inner knee pain. It is often seen in athletes or individuals who perform repetitive hip flexion movements, such as runners or dancers.

12. Stress Fractures

Stress fractures are small cracks in the bone caused by repetitive stress or overuse. When excessive forces are applied to the knee joint, such as in long-distance running or excessive jumping, stress fractures can occur in the bones of the knee joint, leading to inner knee pain. Stress fractures require rest and proper rehabilitation to heal.

It is important to remember that inner knee pain can have multiple contributing factors, and an accurate diagnosis by a healthcare professional is vital for appropriate treatment and management.

Effective Treatment Options for Inner Knee Pain

1. Rest, Ice, Compression, and Elevation (RICE)

This method is a well-known initial treatment approach for reducing inflammation and promoting recovery.

• Rest: Avoid activities that exacerbate the knee pain to allow for healing.
• Ice: Apply ice to the affected area for about 15-20 minutes every 2-3 hours to reduce swelling and pain.
• Compression: Use an elastic bandage to provide support and limit swelling. Ensure it is not wrapped too tightly to avoid restricting blood flow.
• Elevation: Elevate the leg above the heart level whenever possible to reduce fluid accumulation in the knee.

2. Medications and Pain Relief

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Over-the-counter NSAIDs, such as ibuprofen or naproxen, can help reduce pain and inflammation. Prescription-strength NSAIDs may be recommended for more severe pain.

Acetaminophen: For individuals who cannot take NSAIDs due to underlying medical conditions or allergies, acetaminophen may be an alternative for pain relief. However, it does not have the anti-inflammatory effects of NSAIDs.

Topical Analgesics: Creams, gels, or patches containing menthol, capsaicin, or lidocaine can provide temporary pain relief when applied directly to the affected area.

3. Physical Therapy and Rehabilitation

Benefits of Physical Therapy: Physical therapy plays a crucial role in the recovery and rehabilitation of inner knee pain. A physical therapist can design a customized treatment plan to address specific weaknesses, improve flexibility, and promote overall knee health.

Strengthening Exercises: Strengthening exercises focus on improving the strength of the muscles surrounding the knee, such as the quadriceps, hamstrings, and calf muscles. Examples include leg presses, squats, and step-ups.

Range of Motion Exercises: Range of motion exercises help improve flexibility and restore mobility in the knee joint. Examples include heel slides, knee extensions, and hamstring stretches.

Balance and Proprioception Training: Balance and proprioception exercises aim to enhance joint stability and coordination. These exercises can involve standing on one leg, using a balance board, or performing specific movements that challenge balance.

Modalities and Techniques: Physical therapists may also use additional modalities and techniques such as ultrasound, electrical stimulation, heat or cold therapy, and manual therapy to aid in pain relief and recovery.

4. Injections and Minimally Invasive Procedures

Corticosteroid Injections: Corticosteroid injections, administered directly into the knee joint, can provide temporary relief from pain and inflammation. However, they are typically used sparingly due to potential long-term side effects.

Viscosupplementation: Viscosupplementation involves injecting hyaluronic acid into the knee joint to improve lubrication and reduce pain associated with osteoarthritis.

Platelet-Rich Plasma (PRP) Therapy: PRP therapy utilizes the patient’s own blood, which is processed to concentrate platelets and growth factors. The resulting solution is then injected into the knee joint to promote healing and reduce inflammation.

Prolotherapy: Prolotherapy, or regenerative injection therapy, involves injecting a solution (often dextrose) into the knee joint to stimulate the body’s natural healing response and promote tissue repair.

Laser Therapy: Low-level laser therapy may be used to promote tissue healing and reduce inflammation in the knee joint. This non-invasive procedure uses specific wavelengths of light to target affected areas.

5. Surgical Treatments

When Surgery Is Needed: Surgery may be an option if conservative treatments fail to provide relief or if the structural damage to the knee is significant.

Arthroscopic Surgery: Arthroscopic surgery involves using a small camera called an arthroscope and specialized surgical tools to repair or remove damaged tissue in the knee joint. It is a minimally invasive procedure with a shorter recovery time compared to open surgery.

Meniscus Repair or Removal: In cases of severe meniscus tears, a surgeon may repair or remove the damaged portion of the meniscus to alleviate pain and improve knee function.

Ligament Reconstruction: When ligament injuries, such as MCL tears, do not heal with non-surgical treatments, surgical reconstruction may be necessary. This procedure involves using grafts to create a new ligament and restore stability to the knee.

Partial or Total Knee Replacement: For individuals with advanced osteoarthritis or other severe knee conditions, partial or total knee replacement surgery may be considered. In partial knee replacement, only the affected portion of the knee is replaced, while total knee replacement involves replacing the entire knee joint with artificial components.

It is important to consult with a healthcare professional to determine the most suitable treatment approach for your specific condition.
