It's the question almost everyone with FAI asks: do I need surgery, or will this settle on its own? The honest answer: the bony shape doesn't change without surgery — but the symptoms can settle with the right conservative plan in many people. "Going away" doesn't mean reshaping the hip; it means getting the joint tolerating load again and no longer provoking it.
Conservative rehabilitation is the appropriate first-line approach for most symptomatic FAI, with surgery considered when a well-structured plan hasn't given enough improvement.
What "goes away" actually means
FAI symptoms come from the interaction between the hip's shape and how it's loaded — not the shape alone (many pain-free people have the same shape on a scan). So the goal of conservative care isn't to remove the bump or reshape the bone. It's to reduce provocation and rebuild capacity so the same hip stops hurting — even though the underlying shape is unchanged.
The shape doesn't go away. The symptoms often can. Many people return to full activity — running, sport, gym work, daily life — without surgery, by changing how the joint is loaded and rebuilt, not by changing the bone itself.
What conservative treatment can achieve
A specialist plan typically works in four stages, with the goal of restoring tolerance to the loads and ranges that the hip has been avoiding:
- Reduce provocative positions short-term — deep flexion, prolonged sitting, end-range rotation. Not forever, just long enough to settle the joint.
- Build strength and control through the hip and trunk, with a focus on the deep stabilisers and the patterns that matter for your sport or work.
- Progressively reload the sensitive ranges rather than avoiding them indefinitely — graded exposure so the joint adapts back to demanding positions.
- Return to sport with a graded plan that builds tolerance, technique and confidence in the movements that matter to you.
Many people get substantial, lasting relief this way. The plan has to be individualised — generic exercise sheets rarely work for FAI, which is why a specialist assessment matters.
General information, not a personal prescription. The right exercises, loading and progression depend on the individual's examination findings and demands. This article explains the principles — not a specific programme.
Conservative first, surgery when it's the better route
Two paths exist for symptomatic FAI. The right one depends on whether the shape is genuinely driving the pain, how the symptoms respond to a structured plan, and whether there's a specific structural problem best addressed surgically.
Conservative rehabilitation
The first-line approach for most symptomatic FAI. Combines load management, hip and trunk control work, and progressive reload of sensitive ranges. Many people get substantial, lasting relief without surgery.
Best for: symptoms without major structural problem; people who prefer to avoid surgery where possible; active individuals willing to engage with a graded plan.
Hip arthroscopy (surgery)
Reshapes impinging bone and repairs the labrum. Has a role when a well-structured rehab plan hasn't given enough improvement, or when there's a specific structural problem better addressed surgically.
Best for: clear, persistent symptoms that have failed conservative care; a confirmed structural problem best fixed surgically; realistic expectations about post-op rehab.
Importantly, a labral tear on a scan doesn't, by itself, mean surgery is needed. Many labral tears are managed well conservatively, and surgical outcomes are generally better when rehab has been tried properly and the diagnosis is clear. The full pillar page covers the conservative rehabilitation approach in detail: hip impingement, FAI and labral tears.
Why a clear diagnosis comes first
Because the FAI shape is common in pain-free people, the key question isn't "do I have FAI on the scan?" — it's "is my impingement genuinely driving my pain?" Getting that answer right is what makes a conservative plan work — or flags when surgery is the better route.
Without a clear working diagnosis, both paths can be misapplied: surgery performed for a shape that wasn't actually driving the symptoms, or rehab applied to a problem that needed a different approach from the start. The assessment is the foundation.
Red flag: hot, swollen hip with fever
A hot, swollen, feverish hip needs urgent medical assessment today — not physiotherapy. This can indicate infection in the joint (septic arthritis) and requires prompt treatment.
When to see a specialist
If you've been told you have FAI or a labral tear and you're weighing up surgery, a specialist assessment can tell you whether your symptoms are likely to settle conservatively first. The decision between conservative and surgical care shouldn't be made on the scan alone — it should be made on the scan plus the clinical picture.

Can hip impingement heal without surgery?
The bony shape itself doesn't change, but symptoms can settle with a well-structured conservative rehabilitation plan in many people. The goal is to reduce provocation and rebuild capacity, not to remove the shape.
Is surgery necessary for FAI?
Not usually first-line. Conservative care is the appropriate starting point for most symptomatic FAI. Surgery is considered when a well-structured rehab plan hasn't given enough improvement or there's a specific structural problem better addressed surgically.
Does a labral tear always need surgery?
No — many labral tears are managed well conservatively, and a tear on a scan doesn't, by itself, mean surgery is required. Outcomes are generally better when rehab has been tried properly and the diagnosis is clear.
How long does conservative FAI treatment take?
Often a few months of progressive rehabilitation, but the exact timeline varies with the individual — the severity of symptoms, the demands of the sport or job, and how clearly the diagnosis is understood.
