The Glute Medius: The Small Muscle Doing the Heavy Lifting
If you've ever dealt with nagging hip pain, knee discomfort that flares up on runs, or ankles that seem to "give way" more than they should, there's a good chance the real problem isn't where you feel it. It's higher up, in a muscle most people have never consciously engaged: the glute medius.
At Urban Physiotherapy, we see this pattern constantly. Someone comes in pointing to their knee or their ankle, convinced the issue starts there, and the assessment tells a different story. The glute medius is one of the most underrated muscles in the body, and when it's weak, the consequences ripple all the way down the kinetic chain.
What the Glute Medius Actually Does
The glute medius sits on the outer surface of your pelvis, beneath the more famous glute maximus. Its main job is hip abduction (moving the leg out to the side), but its more important role is stabilisation. Every time you take a step, run, or stand on one leg, the glute medius on the standing side contracts to stop your pelvis from dropping on the opposite side.
This is called the Trendelenburg mechanism, and it's happening constantly, whether you're walking to the kitchen or sprinting down a football pitch. When the glute medius does its job properly, your pelvis stays level, your femur stays aligned, and the forces travelling through your leg are distributed the way they're supposed to be. When it doesn't, everything below has to compensate
The Chain Reaction: Hip, Knee, and Ankle
Hip Pain
A weak glute medius often shows up first as lateral hip pain, sometimes diagnosed as greater trochanteric pain syndrome or gluteal tendinopathy. Without adequate abductor strength, the iliotibial band and surrounding tendons take on load they weren't designed to manage, leading to irritation and that deep, aching pain on the outside of the hip.
Knee Pain
This is where it gets interesting for a lot of our patients. A weak glute medius allows the femur to drift into internal rotation and adduction during weight-bearing activities. That inward collapse increases stress on the patellofemoral joint and the IT band, and it's a well-documented contributor to patellofemoral pain syndrome and IT band syndrome, particularly in runners.
Ankle Pain and Instability
The chain doesn't stop at the knee. Poor proximal control changes how load moves through the lower limb, often placing greater demand on the ankle to correct for instability further up. We regularly see patients with recurrent ankle sprains or chronic instability who, on closer assessment, have significant glute medius weakness that's never been addressed.
Balance
Because the glute medius is central to single-leg stability, it's directly tied to balance and fall risk, particularly in older adults. Every step is a single-leg balance challenge for a split second. If that muscle can't do its job, the body relies on smaller, less efficient stabilisers, and balance suffers as a result.
How We Assess It
Weakness here doesn't always show up as obvious muscle soreness. It's more commonly identified through movement compensations: a pelvis that drops on one side during walking or running, knees that cave inward on a single-leg squat, or a Trendelenburg sign on standing hip abduction testing. This is why a proper physiotherapy assessment looks beyond the site of pain and examines how you move as a whole system.
Strengthening the Glute Medius
Strength work needs to progress from control through to load, not jump straight to heavy resistance. A general progression looks like this:
Foundation (activation and control)
Clamshells
Side-lying hip abduction
Standing banded hip abduction
Glute bridges with a resistance band around the knees
Building strength
Single-leg glute bridges
Lateral band walks
Step-ups with a focus on pelvic control
Cable or band hip abduction in standing
Functional and dynamic loading
Single-leg squats with pelvic control
Lateral lunges
Single-leg deadlifts
Sport-specific lateral movement drills
The exercise itself matters less than the quality of execution. Poor form, particularly compensating with the TFL or lower back, defeats the purpose. This is where a tailored program, rather than a generic list of exercises, makes the difference between progress and frustration.
How Urban Physiotherapy Can Help
Glute medius weakness is rarely an isolated issue, and self-diagnosing it from a symptom in your knee or ankle is genuinely difficult without a trained eye. At Urban Physiotherapy, our team assesses your movement patterns as a whole, identifies where the breakdown is actually occurring, and builds a strengthening program specific to your body, your sport, and your goals.
Whether you're dealing with persistent hip pain, recurring knee issues, unstable ankles, or you simply want to move and train with better control, our physiotherapists can pinpoint what's driving the problem and get you on a clear path to resolving it.
If any of this sounds familiar, don't wait for it to become a bigger problem. Book an assessment with our team and let's find out what's really going on. Get in contact with us at (02) 8526 4000 or info@urbanphysiotherapy.com.au
