Ultrasound-Guided Cortisone and Hyaluronic Acid Injections for Patellofemoral Joint (PFJ) Pain at Alton Pain Clinic

 

Introduction

Patellofemoral Joint (PFJ) pain is a frequent source of discomfort in the front of the knee. It can affect individuals of varying ages and activity levels, from young athletes to older adults. PFJ pain often arises from issues between the kneecap (patella) and the underlying femur, leading to discomfort during movements such as climbing stairs, squatting, or sitting for prolonged periods. At Alton Pain Clinic, clinicians use a range of diagnostic and treatment approaches, including ultrasound-guided injections such as cortisone and hyaluronic acid, which are used to support patients in managing their symptoms.

Anatomy of the Patellofemoral Joint

The patellofemoral joint forms part of the larger knee joint complex. It is created by the articulation of the patella with the trochlear groove of the femur. The joint plays a crucial role in:

  • Acting as a lever to improve the efficiency of the quadriceps muscles.
  • Assisting in the smooth gliding of the patella during knee flexion and extension.
  • Protecting the anterior aspect of the knee.

The patella is stabilised by surrounding ligaments, tendons, and soft tissues. Any imbalance or misalignment in these structures can increase pressure on the joint surface and contribute to pain.

Pathology of PFJ Pain

PFJ pain may stem from several underlying issues, including:

  • Maltracking of the patella: When the patella does not move smoothly within the femoral groove.
  • Overuse or repetitive stress: Common in athletes, runners, and those with physically demanding routines.
  • Cartilage changes: Softening or thinning of cartilage in the joint can lead to discomfort.
  • Muscle imbalance: Weakness or tightness in the quadriceps, hip, or hamstring muscles may contribute.
  • Trauma: A direct impact or injury can disrupt joint alignment or surface integrity.

Symptoms of PFJ Pain

Typical features include:

  • Pain around or behind the kneecap, especially during climbing, squatting, or prolonged sitting.
  • Grinding or clicking sensations in the knee.
  • Swelling or tenderness around the patella.
  • Reduced tolerance for physical activities involving the knee.

Diagnosis

Diagnosis of PFJ pain begins with a detailed clinical assessment. Clinicians at Alton Pain Clinic may explore:

  • Patient history, including activity levels and onset of symptoms.
  • Physical examination of knee alignment, stability, and muscle strength.
  • Ultrasound scanning, which can be used for both diagnostic evaluation and guiding injection-based treatments.

Management of PFJ Pain

Management usually involves a combination of approaches depending on the severity and underlying cause. Strategies may include:

  • Injections: Cortisone and hyaluronic acid are among the injectable options offered at Alton Pain Clinic, performed under ultrasound guidance for precision.

Ultrasound-Guided Cortisone Injections

Cortisone injections are used to address inflammation in the patellofemoral joint. Administering these injections under ultrasound guidance allows clinicians to accurately target the joint space, ensuring the medication is delivered where it is needed.

Mechanism of Action of Cortisone
Cortisone belongs to the corticosteroid group and is used to reduce inflammatory processes in the body. Within the PFJ, cortisone may:

  • Reduce inflammatory mediators within the joint.
  • Decrease local tissue swelling.
  • Help alleviate discomfort that may be exacerbated by inflammation.

By moderating the inflammatory response, cortisone injections may provide support in managing PFJ pain, particularly where inflammation is a key component.

Ultrasound-Guided Hyaluronic Acid Injections

Hyaluronic acid is a naturally occurring substance within joint fluid, responsible for lubrication and shock absorption. In some cases of PFJ pain, especially where cartilage surfaces are under stress, hyaluronic acid injections are considered.

Mechanism of Action of Hyaluronic Acid

  • Enhances joint lubrication.
  • Improves the viscoelastic properties of synovial fluid.
  • Supports smoother movement of the patella within the femoral groove.
  • Provides cushioning, which may help reduce joint stress during activity.

At Alton Pain Clinic, hyaluronic acid injections are performed under ultrasound guidance to ensure the substance is placed accurately within the patellofemoral joint.

Combination Approaches

Some patients may be offered different injectable options depending on individual circumstances. For instance, cortisone may be used where inflammation is predominant, whereas hyaluronic acid may be considered in cases of cartilage-related discomfort. Decisions are made based on a thorough assessment and discussion with the clinician.

Role of Ultrasound Guidance

Ultrasound technology allows clinicians at Alton Pain Clinic to:

  • Visualise joint structures in real time.
  • Ensure precise needle placement.
  • Minimise risks of inaccurate delivery.
  • Improve patient comfort during the procedure.

The use of ultrasound enhances both diagnostic accuracy and the effectiveness of interventions.

Why Choose Alton Pain Clinic for PFJ Pain Management?

  • Specialist clinicians with expertise in musculoskeletal conditions.
  • Advanced imaging techniques, including ultrasound guidance for injections.
  • Comprehensive assessment, addressing not only the joint but contributing factors such as muscle strength and biomechanics.
  • Personalised care plans, tailored to individual needs and activity levels.

Conclusion

Patellofemoral Joint pain can significantly affect mobility and quality of life. With its complex anatomy and varied causes, accurate diagnosis and tailored treatment are essential. At Alton Pain Clinic, ultrasound-guided cortisone and hyaluronic acid injections form part of a wider management strategy, delivered with precision and care by experienced clinicians. Through these approaches, patients are supported in addressing PFJ pain in a safe, structured, and patient-centred environment.

Ultrasound-Guided Cortisone Injections for Baxter’s Nerve Entrapment

Image
  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...

Tennis Elbow

  Introduction Tennis elbow , medically known as  lateral epicondylitis , is a condition that affects many individuals, not just athletes. Despite its name, it often arises in people who have never played tennis. It occurs when the tendons in the elbow become irritated, typically due to overuse or repetitive strain. The condition can lead to pain and discomfort, often limiting the ability to carry out daily tasks. At  Alton Pain Clinic , our clinicians frequently see patients experiencing tennis elbow, and we aim to provide an in-depth understanding of the condition. This blog explores its causes, symptoms, anatomy, diagnosis, and various management approaches, including the use of  ultrasound-guided steroid injections  as one of the treatment options we provide. Anatomy of the Elbow To understand tennis elbow, it helps to first appreciate the elbow’s anatomy. The elbow joint connects the  humerus  (upper arm bone) with the  radius  and ...
