Ultrasound-Guided Cortisone and Hyaluronic Acid Injections for Meniscus Tears

 

Introduction to Meniscus Tears

Meniscus tears are among the most common knee injuries, often affecting athletes, active individuals, and older adults. The meniscus, a crescent-shaped cartilage in the knee, serves as a cushion between the femur (thighbone) and tibia (shinbone). A tear in the meniscus can cause significant pain, swelling, and functional limitations.

At Alton Pain Clinic, we specialise in advanced, minimally invasive treatments for musculoskeletal injuries, including ultrasound-guided cortisone and hyaluronic acid injections for meniscus tears. Our tailored approach aims to relieve symptoms and support recovery.

Anatomy of the Meniscus

The meniscus plays a vital role in knee joint function and health.

  • Structure: The knee contains two menisci:
  • Medial Meniscus: Located on the inner side of the knee, it is larger and less mobile.
  • Lateral Meniscus: Found on the outer side of the knee, it is smaller and more mobile.
  • Composition: Made of fibrocartilage, the meniscus is designed to absorb shock and distribute weight.

Function:

  • Provides stability to the knee joint.
  • Reduces stress on the articular cartilage.
  • Enhances joint lubrication and nutrition.

Pathology of Meniscus Tears

Meniscus tears can occur due to acute trauma or degenerative changes over time.

Types of Tears

Traumatic Tears:

  • Common in younger individuals during activities involving twisting or pivoting.
  • Often associated with other injuries, such as anterior cruciate ligament (ACL) tears.

Degenerative Tears:

  • More prevalent in older adults due to cartilage wear and tear.
  • Often linked to osteoarthritis.

Symptoms

  • Pain localised to the affected side of the knee.
  • Swelling and stiffness, particularly after activity.
  • Clicking, locking, or catching sensation in the knee.
  • Reduced range of motion and difficulty bearing weight.

Diagnosis of Meniscus Tears

Accurate diagnosis is essential for effective management.

  • Clinical History: Assessing symptoms, injury mechanism, and activity levels.
  • Physical Examination: Tests such as the McMurray test or Apley grind test to identify meniscal involvement.

Imaging:

  • MRI: Provides detailed visualisation of meniscal tears and associated injuries.
  • Ultrasound: Useful for assessing joint effusion and guiding injections.

At Alton Pain Clinic, our clinicians use advanced imaging and diagnostic techniques to provide a clear understanding of your condition.

Management of Meniscus Tears

Management strategies depend on the type, size, and location of the tear, as well as the patient’s activity level and goals.

Conservative Treatments

  • Rest, Ice, Compression, and Elevation (RICE): Reduces inflammation and promotes initial healing.
  • Physical Therapy: Strengthens the surrounding muscles to stabilise the knee.
  • Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) for symptom relief.

Surgical Interventions

  • Meniscectomy: Removal of the damaged portion of the meniscus.
  • Meniscal Repair: Suturing the torn segments to restore function.
  • Meniscal Transplantation: Replacement with donor tissue for severe cases.

Role of Cortisone and Hyaluronic Acid in Meniscus Tear Management

Ultrasound-guided injections of cortisone and hyaluronic acid offer non-surgical options for managing meniscus tears, targeting inflammation and improving joint health.

Cortisone Injections

Benefits

  • Cortisone, a corticosteroid, is effective in reducing inflammation and alleviating pain in the knee joint.
  • Ultrasound guidance ensures precise delivery to the affected area, enhancing effectiveness while minimising side effects.

Mechanism of Action

  1. Anti-inflammatory Properties: Cortisone inhibits the production of pro-inflammatory cytokines and prostaglandins.
  2. Cell Membrane Stabilisation: Reduces the release of inflammatory mediators.
  3. Pain Reduction: Interrupts inflammatory pathways, providing symptomatic relief.

Hyaluronic Acid Injections

Benefits

  • Hyaluronic acid is a naturally occurring substance in synovial fluid that helps lubricate and cushion the joint.
  • Injections improve joint function and reduce pain, particularly in degenerative conditions.

Mechanism of Action

  1. Viscosupplementation: Restores the natural viscoelastic properties of the synovial fluid.
  2. Anti-inflammatory Effects: Modulates inflammatory pathways within the joint.
  3. Cartilage Protection: Reduces mechanical stress on the articular cartilage.

Ultrasound-Guided Injection Technique

At Alton Pain Clinic, we use ultrasound guidance to ensure precise delivery of cortisone and hyaluronic acid to the affected area.

Procedure Steps

  1. Preparation: The knee is cleaned, and a local anaesthetic is applied for patient comfort.
  2. Imaging: Ultrasound visualisation identifies the optimal injection site.
  3. Injection: The medication is delivered directly into the joint or surrounding tissues, depending on the location of the tear.

Advantages of Ultrasound-Guided Injections

  • Accuracy: Ensures medication is delivered exactly where it is needed.
  • Safety: Minimises the risk of complications by avoiding surrounding structures.
  • Enhanced Outcomes: Improves the effectiveness of the treatment.
