Ultrasound-Guided Cortisone Injections for Patellar Tendonitis

 

Introduction

Patellar tendonitis, commonly known as “jumper’s knee,” is a condition characterised by inflammation of the patellar tendon, which connects the kneecap (patella) to the shinbone (tibia). This condition is common in athletes involved in jumping sports but can also affect individuals engaged in repetitive strain activities or those with biomechanical imbalances. Patellar tendonitis can cause significant discomfort and impact mobility, making effective management essential. At Alton Pain Clinic, we specialise in advanced treatments such as ultrasound-guided cortisone injections to address the symptoms of patellar tendonitis and support patients in their recovery journey.

Patellar tendonitis

Anatomy of the Patellar Tendon

Structure

The patellar tendon is a thick, fibrous band of connective tissue that plays a vital role in knee joint function.

  • Location: It extends from the inferior pole of the patella to the tibial tuberosity.
  • Composition: Comprised mainly of collagen fibres, it is designed to withstand high tensile forces.
  • Function: It transmits the force generated by the quadriceps muscles to the tibia, enabling knee extension and activities like jumping, running, and climbing.

Surrounding Structures

  • Quadriceps Tendon: Connects the quadriceps muscles to the patella.
  • Patella: Acts as a fulcrum, improving the leverage of the quadriceps tendon.
  • Bursa: Small sacs of fluid around the tendon reduce friction between the tendon and adjacent tissues.

Pathology of Patellar Tendonitis

Definition

Patellar tendonitis is an overuse injury caused by repetitive stress on the patellar tendon, resulting in microtears and inflammation.

Causes

  1. Repetitive Stress: Frequent jumping or running can overload the tendon.
  2. Sudden Increase in Activity: Abrupt changes in exercise intensity or volume can contribute to tendon strain.
  3. Biomechanical Factors: Poor alignment, weak quadriceps, or tight hamstrings may increase tendon stress.
  4. Inappropriate Footwear: Wearing shoes that do not provide adequate support can exacerbate strain.

Symptoms

  • Pain at the lower pole of the patella, especially during activity.
  • Stiffness or discomfort in the tendon during movement.
  • Swelling or thickening of the tendon in some cases.
  • Pain that worsens with activities like jumping, climbing stairs, or squatting.

Diagnosis of Patellar Tendonitis

Comprehensive Assessment

At Alton Pain Clinic, we utilise a systematic approach to diagnosing patellar tendonitis:

  1. Medical History: Gathering details about symptoms, activity levels, and prior injuries.
  2. Physical Examination: Checking for tenderness at the patellar tendon and evaluating knee function.
  3. Imaging Studies: Ultrasound or MRI is used to confirm the diagnosis, revealing thickening of the tendon or signs of inflammation.

Management of Patellar Tendonitis

Treatment of patellar tendonitis typically involves a combination of conservative and advanced therapeutic options.

Conservative Management

  1. Activity Modification: Reducing activities that exacerbate pain to allow the tendon to heal.
  2. Physical Therapy:
  • Stretching Exercises: To improve flexibility in the quadriceps and hamstrings.
  • Strengthening Exercises: To build resilience in the quadriceps and surrounding muscles.

Advanced Treatments

For persistent or severe cases, further intervention may be necessary:

  1. Ultrasound-Guided Cortisone Injections: A targeted approach to reduce inflammation and pain.

Precision Treatment

Cortisone injections are a minimally invasive treatment that delivers anti-inflammatory medication directly to the affected area. Ultrasound guidance ensures precise delivery, improving outcomes while minimising risks.

Benefits of Ultrasound Guidance

  • Enhanced Accuracy: Direct visualisation of the patellar tendon ensures precise placement of the injection.
  • Improved Safety: Surrounding structures such as blood vessels and nerves are avoided.
  • Optimised Outcomes: Accurate delivery of cortisone maximises its therapeutic effects.

Mechanism of Action of Cortisone

Cortisone, a corticosteroid, works by modulating the body’s inflammatory response.

  • Reduction of Inflammatory Mediators: Cortisone inhibits the production of substances like prostaglandins and cytokines that drive inflammation.
  • Stabilisation of Cell Membranes: It prevents the release of enzymes that can damage tissues during inflammation.
  • Pain Relief: By addressing the underlying inflammation, cortisone helps to reduce pain and improve function.
