Ultrasound-Guided Cortisone for Iliotibial Band Syndrome at Alton Pain Clinic

 

Introduction

Iliotibial Band Syndrome (ITBS) is a frequent musculoskeletal condition affecting individuals who take part in repetitive knee movements such as running, cycling, and long-distance walking. It is one of the most common causes of pain on the outer side of the knee and can significantly interfere with physical activity and daily routines. The problem arises when the iliotibial band becomes irritated as it crosses the lateral aspect of the knee joint.

At Alton Pain Clinic, we focus on accurate diagnosis and tailored management options for ITBS, including the use of ultrasound-guided cortisone injections. This blog explores ITBS in depth, covering anatomy, pathology, symptoms, diagnosis, management strategies, and the role of cortisone as part of treatment.

Anatomy of the Iliotibial Band

The iliotibial band (ITB) is a dense band of connective tissue extending from the iliac crest at the top of the pelvis to its attachment at Gerdy’s tubercle on the tibia. Along its course, it receives input from the tensor fasciae latae and gluteus maximus muscles, enabling it to act as a stabiliser for the hip and knee.

As the ITB crosses the lateral femoral condyle, it helps control knee movement during running and walking. However, this close relationship to the femoral condyle makes the area susceptible to friction and compression, particularly during repetitive flexion and extension.

Pathology of Iliotibial Band Syndrome

The underlying pathology of ITBS is multifactorial, with two main theories:

  1. Friction Theory
     Suggests that the ITB rubs repeatedly over the lateral femoral condyle, leading to local irritation.
  2. Compression Theory
     Proposes that the ITB compresses sensitive tissue between itself and the femur, producing pain and irritation.

Histological findings often show thickening of the band, irritation of the adjacent bursae, and changes in vascular tissue. These changes reflect the mechanical stress endured during repetitive movement.

Risk Factors

ITBS may be influenced by a range of factors:

  • Biomechanical: Excessive pronation, limb length discrepancy, or hip abductor weakness.
  • Training: Sudden increases in running mileage, downhill running, or inadequate recovery between sessions.
  • Environmental: Running on sloped surfaces or uneven terrain.
  • Equipment: Inappropriate footwear or poor cycling biomechanics.

Clinical Features

Symptoms of ITBS typically present as

  • Sharp or burning pain over the outer knee, often aggravated by repetitive activities.
  • Pain appearing during exercise, particularly running or cycling.
  • Tenderness over the lateral femoral condyle.
  • Pain reproduced by the Noble Compression Test or a positive Ober’s Test.
  • In some cases, a snapping or popping sensation may be reported.

Initially, pain may only occur after prolonged exercise but, if not addressed, it can appear earlier and even during daily activities.

Diagnosis

ITBS is usually diagnosed through a detailed clinical history and examination. Investigations may support the diagnosis or exclude alternative causes:

  • Ultrasound: May show thickened tissue or increased vascularity.

It is important to distinguish ITBS from other conditions such as lateral meniscus pathology, patellofemoral pain, or ligament injuries.

Management Approaches

Management of ITBS involves a combination of conservative strategies and, if required, targeted interventions.

Conservative Strategies

  • Rest and Activity Modification: Avoiding or reducing aggravating activities.
  • Manual Therapy: Techniques to reduce tightness and restore mobility.
  • Footwear and Equipment Adjustments: Ensuring proper support for biomechanics.

Ultrasound Guidance in Injections

Ultrasound allows direct visualisation of the iliotibial band, femoral condyle, and surrounding tissue. With this technology, clinicians can guide the needle to the intended site with accuracy, avoiding nearby structures and ensuring the injection is delivered effectively.

At Alton Pain Clinic, ultrasound guidance is routinely used to provide precision in musculoskeletal injections, allowing for a more targeted and confident approach.

Cortisone and Its Role in ITBS

Cortisone is a corticosteroid used in musculoskeletal medicine to reduce local tissue irritation. In the context of ITBS, cortisone may be considered when symptoms persist despite conservative care.

Mechanism of Action

  • Anti-Inflammatory Effects: Cortisone limits the release of inflammatory mediators.
  • Reduced Vascular Permeability: Helps to decrease fluid accumulation in the irritated tissues.
  • Immune Modulation: Regulates immune cell activity contributing to irritation.
  • Pain Reduction: By lessening inflammation and tissue stress, cortisone reduces nociceptive signalling.

This multi-faceted mechanism provides a rationale for the use of cortisone injections in ITBS.

Benefits of Ultrasound-Guided Cortisone for ITBS

Using ultrasound guidance offers several advantages:

  • Clear visualisation of the target area.
  • Accurate delivery of cortisone.
  • Avoidance of nearby anatomical structures.
  • Improved confidence in needle placement.

In ITBS, where the band lies close to bone and soft tissue structures, such accuracy is particularly valuable.

Why Choose Alton Pain Clinic

At Alton Pain Clinic, our approach to ITBS integrates technology, clinical expertise, and tailored care:

Conclusion

Iliotibial Band Syndrome is a leading cause of outer knee pain, particularly in athletes and active individuals. Its pathology is linked to repetitive irritation of the iliotibial band over the lateral femoral condyle. While many cases improve with conservative management, ultrasound-guided cortisone injections may be used in situations where symptoms remain troublesome.

At Alton Pain Clinic, we place emphasis on precision, tailored treatment, and comprehensive care. By combining detailed clinical assessment with ultrasound-guided procedures, our clinicians aim to support individuals in managing ITBS and restoring confidence in movement.

  Introduction Baxter’s Nerve Entrapment , also known as inferior calcaneal nerve entrapment, is a condition that can contribute to chronic heel pain. It is often misdiagnosed as plantar fasciitis due to the overlap in symptoms. The condition arises when the first branch of the lateral plantar nerve, known as Baxter’s nerve, becomes compressed or irritated. Anatomy of Baxter’s Nerve Baxter’s nerve is a branch of the lateral plantar nerve, which originates from the tibial nerve. This small but significant nerve travels along the medial aspect of the heel and innervates the abductor digiti minimi muscle of the foot. Due to its anatomical course, Baxter’s nerve is prone to compression between the deep fascia of the abductor hallucis muscle and the medial calcaneal tuberosity. Pathology and Causes of Entrapment Baxter’s nerve entrapment  occurs when the nerve is compressed or irritated due to various factors, including: Repetitive stress and overuse  — Activities such as prol...
