Overview
What is legg-calve-perthes disease?
Legg-Calve-Perthes disease is a childhood hip disorder where temporary loss of blood supply to the femoral head causes the ball of the hip to soften and reshape during a vulnerable growth window. Symptoms can develop gradually or after a specific injury, so early evaluation matters when function starts to decline.
Most patients with legg-calve-perthes disease improve with conservative care — targeted physical therapy, image-guided injections, bracing or supportive footwear when relevant, and activity modification. When conservative care isn't enough or imaging shows structural injury that won't heal on its own, our specialists offer the next-step procedures discussed below.
Below, we walk through the anatomy involved, the symptoms and causes we most often see, how we diagnose legg-calve-perthes disease, and the full range of treatment options — from the simplest to the most involved.
Patient education
Watch: Legg-Calve-Perthes Disease (LCPD)
This disease most commonly affects children between the ages of four and eight. It involves the head of the femur. That's the bony ball that goes into the hip socket. With this disease, the bone of the femur's head begins to die.

Anatomy of the hip — femoral head, acetabulum, labrum, and surrounding ligaments.
Anatomy
Inside the hip.
The hip is a ball-and-socket joint built for both stability and a wide range of motion. The ball (femoral head) sits inside the socket (acetabulum) and is cushioned by smooth cartilage. The labrum — a rim of cartilage around the socket — adds depth and a seal. Most hip pain comes from wear of that cartilage, labral injury, or bony impingement between the ball and socket.

Diagnostics
How we diagnose legg-calve-perthes disease
You want answers, fast — and we're built to give them. Most patients leave their first LAOSS visit with a clear diagnosis and a written plan, not another referral chain.
Here's what your initial visit for legg-calve-perthes disease typically looks like:
- Detailed history — when it started, what makes it better or worse, what you've already tried
- Focused exam of the hip — range of motion, stability, strength, specific provocation tests
- On-site imaging at most offices: X-ray for bone, ultrasound or MRI when soft-tissue detail is needed
- A written plan with options ranging from conservative care to surgical procedures, in plain English

Treatment options
How we treat legg-calve-perthes disease at LAOSS
Once we've confirmed the diagnosis, the next step is matching the right treatment to your situation. We start with the least-invasive option that fits — and escalate only when it doesn't.
Conservative care
Step 1Conservative care first
Non-surgical options designed to relieve pain, restore movement, and avoid the OR when possible.
- Physical therapy & gait re-training
- Image-guided steroid or anesthetic injections
- Activity modification & weight management
- PRP & regenerative injections
- Bracing or assistive devices when needed
Surgical care
When neededSurgical options when needed
Minimally invasive and reconstructive procedures performed by board-certified orthopedic surgeons.
- Hip arthroscopy for labral repair or FAI
- Femoral / acetabular osteotomy in select cases
- Anterior or posterior total hip replacement
- Revision hip replacement
- Fracture fixation when trauma is the cause
Surgeon expertise
Why experience matters.
Why experience matters
Hip care is highly technique-dependent. Volume, training, and judgment together determine the outcome you actually feel six months later.
- Precise diagnosis from imaging and exam
- Conservative-first care that avoids unnecessary surgery
- Surgical technique refined over thousands of cases
- On-site imaging + coordinated PT through your in-network provider
The LAOSS approach
Our hip specialists move stepwise — start with the least-invasive option that fits your situation, escalate only when it doesn't.
- Same-day imaging at most offices
- PT coordinated in your insurance network
- Board-certified surgeons performing the procedures themselves
- Direct access to your specialist between visits
Candidacy
Am I a candidate?
If most of these match your situation, an evaluation with a hip specialist is the next step.
You may be
You may be a candidate if
These signs typically point toward an in-person evaluation with a hip specialist.
- Pain or stiffness in the hip that lasts more than a few days
- Swelling, instability, or noticeable change in function
- Symptoms that limit walking, lifting, sleep, or work
- Previous treatment that didn't fully resolve the problem
- Imaging or exam findings that suggest an underlying issue
Evaluation
What evaluation includes
Your first visit is built to give you an answer the same day, not just another referral.
- Detailed history — onset, mechanism, what makes it better or worse
- Hands-on exam focused on the affected joint or region
- On-site imaging at most offices (X-ray, ultrasound)
- Clear plan with options ranging from conservative to surgical
- Same-day or next-day scheduling for any follow-up tests
ImportantSeek urgent evaluation for sudden severe pain, numbness, progressive weakness, loss of bowel or bladder control, or any sign of infection (fever, increasing redness or swelling).

Risks & considerations
What to weigh before you decide.
We talk through the risks and benefits with every patient — informed consent is a conversation, not a form.
General
General considerations
Every orthopedic intervention carries a small set of standard risks. We screen, prepare, and monitor for these on every patient.
- Infection (rare with modern technique and prophylaxis)
- Bleeding or bruising at the treatment site
- Reaction to anesthesia or medications
- Need for additional procedures in some cases
Specific
Hip-specific considerations
Some risks are tied to the structures we're treating in the hip. We discuss these in detail at your visit so you can weigh them against the benefits.
- Temporary stiffness or weakness during recovery
- Incomplete pain relief in a small percentage of cases
- Nerve or vessel irritation near the treatment area
- Need for follow-up therapy to fully restore function

FAQ
Common legg-calve-perthes disease questions
- We start with a focused orthopedic exam and detailed history. X-rays are usually done in-office; MRI or ultrasound is ordered when soft-tissue detail is needed. Most patients leave the first visit with a clear diagnosis and a written plan.
- Most legg-calve-perthes disease patients improve with conservative care — therapy, bracing, medication, and image-guided injections when appropriate. Surgery is reserved for cases where structural injury or persistent symptoms warrant it, and we explain every option before any decision.
- If hip pain lasts more than a few days, limits movement, or interferes with daily activities, it's time to see a doctor. Sudden injuries, swelling, or weakness should be evaluated right away.
- If you have a PPO plan, no referral is needed — book directly with any of our specialists. HMO plans require a referral from your PCP. If you are unsure, call us at (323) 264-7600 and our team will walk you through it.
