Knee pain at the front of the joint is a common complaint, particularly in those who are active or spend long hours on their feet. When scans show no obvious cartilage damage or ligament injury, the cause is often biomechanical rather than structural.
One frequently overlooked reason is patella maltracking, where the kneecap doesn’t glide smoothly within its groove as the knee bends and straightens. Understanding why this happens is the first step toward effective treatment.
How the kneecap is meant to move
The patella sits within the quadriceps tendon and glides up and down a shallow groove at the end of the thigh bone called the trochlea. During normal knee movement, the patella should track centrally within this groove, distributing forces evenly across the joint surface.
Patella maltracking occurs when this movement becomes uneven, most commonly drifting slightly towards the outside of the knee. Over time, this abnormal motion increases pressure on certain areas of cartilage and surrounding soft tissues, leading to pain, irritation, and sometimes swelling.
Common symptoms of patella maltracking include:
- Anterior knee pain, particularly with stairs, squatting, running or prolonged sitting.
- Aching or pressure around or behind the kneecap during or after activity.
- Grinding, clicking or creaking sensations when bending the knee.
- Sensation of instability or the kneecap slipping out of position.
A detailed assessment is crucial as these symptoms can point to other causes of anterior knee pain.
Why patella maltracking happens
Patella maltracking is rarely caused by a single issue, and usually results from a combination of anatomical and biomechanical factors working together.
Muscle imbalance is one of the most common contributors. Weakness in the inner quadriceps muscle allows the patella to be pulled laterally by stronger outer structures. At the same time, reduced strength or control in the gluteal muscles can affect hip position, altering the alignment of the entire leg during movement.
Foot mechanics and training habits can add to the problem. Excessive foot pronation, sudden increases in activity, or repetitive loading without adequate recovery, all increase stress through the patellofemoral joint. Over time, these forces can overwhelm the body’s ability to compensate, resulting in pain.
Non-surgical management and when it helps
For many patients, early patella maltracking responds well to physiotherapy. Treatment focuses on improving muscle balance and movement patterns. Strengthening the quadriceps, particularly the inner portion, alongside targeted hip and glute exercises helps guide the patella into a more central position during activity.
Taping or bracing can offer temporary symptom relief by improving tracking and reducing irritation during exercise.
If symptoms persist despite well-structured rehabilitation, further assessment is needed.
Surgical realignment and tibial tubercle transfer
When patella maltracking is driven by underlying bony alignment issues, tibial tubercle transfer surgery may be considered.
The tibial tubercle is the point where the patellar tendon attaches to the shin bone. In this procedure, a small piece of the shin bone is removed and carefully repositioned. By correcting the mechanical pathway of the patella, pressure within the joint becomes more evenly distributed, reducing pain and improving function.
This procedure is helpful for patients with recurrent pain, instability, or progressive cartilage wear who have not improved with physiotherapy alone. Recovery involves a structured rehabilitation programme to restore strength and confidence in the knee.
If knee pain is limiting your activity, a specialist assessment can help identify whether maltracking is the underlying issue. Book a consultation with Mr Shah Punwar.
