Got groin pain?

The adductor muscles are a group of muscles that extend from the pelvis down the inner thigh to the knee. They function to bring the leg back from side extension and inward across the midline of the body.

As pelvic stabilisers, they play a crucial role in dynamic movements involving the leg. They help with pelvic and trunk control during the single-leg stance phase of gait (walking) and also contribute to hip flexion and leg rotation, to a lesser extent.

Weakness in the adductors can lead to issues with lumbo-pelvic stability, such as poor lateral stability and uncontrolled weight shifts during single-leg stance.

Additionally, because of their connections to the abdominal muscles, adductors also assist in maintaining anterior pelvic stability.

Q&A with Cam

What is the most common Adductor muscle injury you see in the Clinic?

Adductor strains, mostly grade 1 or 2 They're milder than a complete tear, but still coming from the same kind of movements. I see this constantly in athletes doing dynamic, multi-directional sport: netball, volleyball, tennis, AFL, soccer, anything with quick changes of direction.

Standard management applies. Rest, ice, compression, then easing back into stretching and strengthening to get you moving properly again without setting yourself up for a repeat.

First, work out what you're actually dealing with. Mechanism of injury and grade of injury matter, and sometimes that means imaging like X-ray, ultrasound, or MRI. From there, it's not just about the groin itself. Poor hip mobility and weak lumbo-pelvic control are usually part of the picture too, so addressing those are what stops it coming back.

For hip mobility:

For lumbo-pelvic control:

As you progress, shift focus to lateral and multi-directional stability — that's where most groin re-injuries actually happen.

Not that often. Honestly, they're less common than strains. When they do happen, it's usually from overstretching or over-contracting the muscle suddenly, like slipping on a wet surface, stepping awkwardly on uneven ground, or kicking a football.

You'll usually know straight away, a pop or tearing sensation, immediate pain, with bruising showing up over the next few hours to days. Walking gets difficult, and the leg feels weak.

If this happens: ice it, compress it, avoid weight-bearing if it's bad, and get a proper diagnosis quickly rather than guessing at severity yourself.

For a muscle tear, generally 4-6 weeks. If the tendon's involved, you can double that. Getting an accurate diagnosis early makes a real difference to how smoothly that timeline goes.

If it's just tightness rather than an actual tear, good hip mobility and core and adductor strengthening can shift things quickly, often within days.

For more significant tears, especially where the muscle's pulled away from its attachment point, surgery may be needed. Location matters as much as grade here. Tears at the tendon or muscle-tendon junction tend to be the most serious and take longest to come back from.
