Hip Arthroscopy in Singapore: Keyhole Surgery for Labral Tears and Impingement

Hip pain can quietly take over your life, whether it stops you from finishing a morning run, makes it harder to keep up with your children, or simply disrupts your sleep. If you have been dealing with persistent groin pain, a clicking sensation in your hip, or stiffness that does not respond to rest, hip arthroscopy is a procedure that may help active individuals and athletes address the root cause of their hip pain without the demands of traditional open surgery.

Understanding Hip Arthroscopy

Hip arthroscopy is a minimally invasive surgical procedure in which a surgeon inserts a small camera (called an arthroscope) and fine instruments through two or three tiny incisions around the hip joint to diagnose and treat internal hip problems, without the need for a large surgical opening.

Think of it like using a periscope to see and fix something inside a sealed container, rather than cutting the container open entirely. The surgeon watches a live video feed on a monitor and works with precision instruments guided by that image.

This approach is particularly relevant for conditions that affect the soft tissues and bone structures inside the hip joint, where traditional imaging may identify a problem but cannot resolve it on its own.

Conditions Suitable for Hip Arthroscopy

Hip arthroscopy is well-suited to a specific group of conditions that affect the internal structures of the joint, including acetabular labral tears, femoroacetabular impingement, chondral lesions, ligamentum teres tears, loose bodies, synovial chondromatosis, and certain pediatric hip disorders such as developmental dysplasia and slipped capital femoral epiphysis.

Labral Tears

The labrum is a ring of cartilage (firm but flexible tissue) that lines the rim of your hip socket. Its job is to deepen the socket, cushion the joint, and help keep the ball of your thigh bone seated securely. A hip labral tear means this cartilage has been damaged, either through a sudden injury, repetitive movement, or gradual wear.

Common symptoms of a labral tear include:

• A sharp or deep ache in the groin or front of the hip.
• A clicking, locking, or catching sensation when you move.
• Pain that worsens with prolonged sitting, walking, or pivoting movements.
• Stiffness or a reduced range of motion in the hip.

Runners, footballers, dancers, and golfers are among those who may be more susceptible to labral tears, though the condition can also develop in people with no sporting background.

During hip arthroscopy, the surgeon can trim away the torn portion of the labrum or, where appropriate, repair and reattach it to support its function.

Femoroacetabular Impingement (FAI)

Femoroacetabular impingement (FAI) is a condition in which the ball and socket of the hip joint do not fit together smoothly, causing them to pinch or rub against each other during movement. The term “femoroacetabular” refers to the two bones involved: the femur (thigh bone) and the acetabulum (hip socket).

FAI typically occurs in one of two forms:

• Cam Impingement: An abnormal bump develops on the head of the femur, disrupting the smooth gliding motion of the joint.
• Pincer Impingement: The rim of the hip socket extends too far, causing it to over-cover the femoral head and create friction.

Many people have both types simultaneously. FAI is a recognized underlying cause of labral tears and, if left unaddressed, may contribute to progressive cartilage damage over time.

Hip arthroscopy allows the surgeon to reshape the bone to address the impingement and reduce further wear on the joint.

Other Suitable Conditions

Beyond labral tears and FAI, hip arthroscopy may also be used to address:

• Loose Bodies: Small fragments of bone or cartilage that have broken free inside the joint, causing pain and locking.
• Synovitis: Inflammation of the joint lining (synovium) that causes swelling and discomfort.
• Hip Joint Infections: In selected cases, arthroscopy can be used to wash out the joint.
• Snapping Hip Syndrome: Where a tendon or tissue band catches on a bony prominence, producing an audible or felt snap.

How Hip Arthroscopy Is Performed in Singapore

Hip arthroscopy is performed by an orthopaedic surgeon using a camera and specialised instruments inserted through small incisions around the hip, typically under general or spinal anaesthesia, with the procedure lasting between one and two hours depending on the complexity of the work required.

Pre-Operative Assessment and Imaging

Before surgery is considered, your surgeon will conduct a clinical assessment. This usually includes:

• A detailed history of your symptoms, including when the pain started, what aggravates it, and how it affects your daily life.
• A physical examination to assess your range of motion, strength, and specific impingement tests.
• Imaging studies, most commonly an X-ray to assess bone structure, followed by an MRI (magnetic resonance imaging) or MR arthrogram (an MRI enhanced with a contrast dye injected into the joint) to evaluate soft tissues, including the labrum and cartilage.

This pre-operative workup helps confirm the diagnosis, identify conditions that may not be suitable for arthroscopic treatment, and plan the surgical approach.

What Happens During the Procedure

On the day of surgery, you will be positioned on a traction table. Gentle traction (a controlled pulling force) is applied to the leg to create a small gap in the hip joint, giving the surgeon enough space to insert the arthroscope.

The surgeon then:

1. Makes two or three small incisions (typically less than one centimetre each) around the hip.
2. Inserts the arthroscope through one incision to view the joint on a monitor.
3. Passes fine surgical instruments through the other incisions to perform the necessary repair, reshaping, or removal.
4. Closes the incisions with small sutures or adhesive strips.

Because the incisions are small and the surrounding muscles are not cut or detached (as they would be in open surgery), the disruption to the hip is generally less than with open surgical approaches.

Anaesthesia and Surgical Duration

Hip arthroscopy is generally performed under general anaesthesia (where you are fully asleep) or spinal anaesthesia (where the lower body is numbed). Your anaesthetist will discuss the most appropriate option based on your health profile.

The procedure itself typically takes between one and two hours, though more complex cases involving both bone reshaping and labral repair may take longer. Most patients are admitted on the same day as surgery and discharged within one to two days, depending on individual circumstances.

Candidacy for Hip Arthroscopy

Hip arthroscopy tends to produce more favourable outcomes for a specific group of patients. Suitability depends on several individual factors, which the following table summarises.

Note: This table serves as a general guide. A thorough consultation with an orthopaedic specialist can help determine whether hip arthroscopy is appropriate for your specific situation. Factors such as severe hip dysplasia or significant cartilage loss may mean that a different surgical approach is more clinically appropriate.

Hip Arthroscopy Versus Open Hip Surgery

The choice between these approaches depends on an individual’s condition, joint anatomy, and surgical goals.

When Open Surgery May Be More Appropriate

Open hip surgery, including procedures such as total hip replacement (joint replacement surgery) or periacetabular osteotomy (a bone-cutting procedure to reposition the hip socket), may be more appropriate when the joint shows significant arthritic damage, when there is substantial structural deformity, or when prior arthroscopic treatment has not provided adequate relief.

Recovery After Hip Arthroscopy

Many patients are able to walk with crutches on the day of surgery or the day after. A gradual return to normal daily activities over four to six weeks is common, with return to sport typically occurring between four and six months, depending on the extent of the procedure and individual progress.

The First Few Weeks After Surgery

The early recovery phase focuses on protecting the repaired tissues while gently restoring movement. During the first two weeks, patients can generally expect:

• Walking with crutches to reduce weight through the hip.
• Prescribed pain relief to manage post-operative discomfort.
• Ice application and leg elevation to help manage swelling.
• Blood-thinning medication as prescribed to reduce the risk of blood clots.
• Wound care and a follow-up appointment to check healing.

Many patients find that discomfort in the first week is manageable with medication, and that it reduces noticeably by the second and third week.

Physiotherapy and Rehabilitation Milestones

Physical therapy is a central part of recovery after hip arthroscopy. A structured rehabilitation programme typically progresses through several phases:

• Weeks 1 to 4: Gentle range-of-motion exercises, hip muscle activation, and protected weight-bearing.
• Weeks 4 to 8: Progressive strengthening of the hip, core, and surrounding muscles; weaning off crutches.
• Weeks 8 to 12: Low-impact cardiovascular exercise (such as stationary cycling or swimming) and continued strengthening.
• Months 3 to 6: Sport-specific training and gradual return to full activity.

Returning to Sport and Daily Activities

General timelines for returning to activities vary depending on the procedure performed:

• Driving: Typically 4 to 6 weeks (right hip surgery may require longer).
• Desk Work: Often within 2 to 4 weeks.
• Light Exercise (Walking, Swimming): Around 6 to 8 weeks.
• Running: Approximately 3 to 4 months.
• Contact or High-Impact Sports: 4 to 6 months, subject to physical therapy clearance.

Potential Risks and Realistic Outcomes

As with any surgical procedure, hip arthroscopy carries a small risk of complications.

Potential risks include:

• Infection: Uncommon but possible; managed with antibiotics and, in rare cases, further intervention.
• Nerve or Vessel Injury: The proximity of nerves and blood vessels to the hip joint means there is a small risk of temporary numbness or, very rarely, more significant injury.
• Traction-Related Complications: The traction used to access the joint can occasionally cause temporary numbness or pressure-related discomfort in the groin or foot.
• Stiffness or Incomplete Recovery: Some patients may not regain full range of motion, particularly if cartilage damage was more extensive than anticipated.
• Need for Further Surgery: In some cases, symptoms may recur or progress, and additional procedures (including hip replacement) may be required in the future.

Serious complications are uncommon. Clinical outcomes vary by individual; patients with well-preserved cartilage and a clearly identified structural cause for their symptoms tend to achieve more favourable results.

When to Seek Professional Help

Not all hip discomfort requires urgent attention, but certain symptoms suggest it may be worth consulting a hip specialist in Singapore rather than waiting to see if things improve independently.

You may wish to seek professional evaluation if you experience:

• Persistent groin pain or deep hip pain lasting more than 4 to 6 weeks.
• A clicking, locking, or catching sensation inside the hip joint.
• Pain that limits your ability to participate in sport, exercise, or regular daily activities.
• Hip stiffness that is worse in the morning or after prolonged sitting.
• Pain that disrupts your sleep or makes it difficult to find a comfortable resting position.
• Symptoms that have not improved with rest, physical therapy, or anti-inflammatory medication.

Many hip conditions respond well to conservative management, including physical therapy, activity modification, and targeted exercises. Early assessment helps identify the cause and supports timely management of conditions such as labral tears or femoroacetabular impingement.

Commonly Asked Questions

How long does recovery from hip arthroscopy take?

Full recovery from hip arthroscopy typically takes between four and six months, though many patients return to light daily activities within four to six weeks and desk-based work within two to four weeks. The timeline depends on the complexity of the procedure, the extent of any labral repair or bone reshaping performed, and physical therapy compliance.

Is hip arthroscopy painful?

Discomfort after hip arthroscopy is expected in the first one to two weeks and is managed with prescribed pain relief. Many patients describe the post-operative pain as manageable. Soreness and stiffness can continue during rehabilitation as the hip is progressively loaded, but this generally improves over subsequent weeks.

Can hip arthroscopy reduce the need for hip replacement later?

In appropriate candidates, addressing structural problems such as FAI and labral tears through hip arthroscopy may help reduce ongoing stress on joint cartilage. Whether this influences the likelihood or timing of hip replacement depends on the degree of cartilage damage already present at the time of surgery.

How much does hip arthroscopy cost in Singapore?

The cost of hip arthroscopy in Singapore varies depending on surgeon fees, facility charges, implant consumables, and the complexity of the procedure. You can request a detailed, itemised cost estimate from your clinic prior to scheduling.

What should I look for when choosing a hip arthroscopy surgeon in Singapore?

Consider their subspecialty fellowship training, experience in keyhole hip surgery, familiarity with your specific diagnosis, and whether they provide a clear, structured physical therapy rehabilitation pathway.

Next Steps

If you are considering a specialist consultation with a hip surgeon, these practical steps can help you prepare:

• Keep a symptom diary: Note when your hip pain occurs, what activities trigger it, and how it affects your daily life. This information is genuinely useful to your surgeon.
• Gather your imaging: If you have had an X-ray or MRI of your hip, bring the images and reports to your consultation.
• List your questions: Write down what you want to know, including questions about diagnosis, surgical options, and recovery expectations.

Coming prepared helps your specialist provide guidance that is relevant to your individual situation from the first visit.
