Understanding Patellofemoral Maltracking and Orientation
Overview:
Patellofemoral maltracking refers to the improper movement of the patella (kneecap) within the femoral groove during knee motion. This misalignment can lead to anterior knee pain and is often associated with conditions like Patellofemoral Pain Syndrome (PFPS). Jenny McConnell, an Australian physiotherapist, has significantly contributed to understanding and managing this condition through her assessment techniques and taping methods.
What is Patellofemoral Maltracking?
In a healthy knee, the patella glides smoothly within the femoral trochlea during flexion and extension. Maltracking occurs when the patella deviates from this path, often shifting laterally. Factors contributing to maltracking include:
- Muscle imbalances
- Structural abnormalities
- Improper biomechanics
Symptoms typically include anterior knee pain, especially during activities like climbing stairs, squatting, or prolonged sitting.
Jenny McConnell's Contribution
Jenny McConnell developed a comprehensive approach to assess and manage patellar malalignment. Her method involves evaluating the patella's position in three planes:
- Glide: Lateral or medial displacement of the patella relative to the femoral condyles.
- Tilt: Angulation of the patella's lateral or medial border relative to the frontal plane.
- Rotation: Deviation of the patella's inferior pole relative to the long axis of the femur.
This assessment guides targeted interventions, including specific taping techniques and exercises to correct
malalignment.
Measuring Patellar Orientation
Accurate assessment of patellar orientation is crucial for diagnosing maltracking and planning treatment. Common measurement techniques include:
- Glide Assessment: Measuring the distance from the mid-patella to the medial and lateral femoral epicondyles to determine lateral or medial displacement.
- Tilt Assessment: Evaluating the height difference between the anterior aspects of the medial and lateral patellar borders to assess angulation.
- Rotation Assessment: Observing the alignment of the patella's inferior pole relative to the femur's long axis to identify rotational deviations.
These measurements can be performed clinically and are often supplemented with imaging studies for enhanced
accuracy.
McConnell Taping Technique
Based on the assessment, Jenny McConnell introduced a taping method designed to:
- Correct patellar alignment
- Reduce pain
- Improve function
The technique involves applying adhesive tape to reposition the patella medially, adjust tilt, or modify rotation as needed. This approach
allows patients to engage in rehabilitation exercises with reduced discomfort, facilitating recovery.
Sport Bracing Options
From our experience at Offaly Physio and Performance Lab we find the Donjoy webtech knee brace the most successful brace for maintaining patella position.
