What Is a Hip Arthroscopy?
Hip arthroscopy is a minimally invasive surgical procedure used to diagnose and treat conditions inside the hip joint. Through small incisions, an orthopaedic surgeon inserts a thin camera (arthroscope) and specialised instruments to repair or remove damaged tissue.
This technique is often used to treat issues such as:
- Labral tears (injuries to the cartilage rim around the hip socket)
- Femoroacetabular impingement (FAI), where abnormal bone growth causes painful friction
- Loose fragments of bone or cartilage
- Inflammation of the hip lining (synovitis)
Because it is minimally invasive, hip arthroscopy usually involves shorter hospital stays, smaller scars and faster recovery compared to open procedures. However, it is not suitable for everyone; for example, those with advanced arthritis.
What Is a Hip Replacement?
Hip replacement, or total hip arthroplasty, is a more extensive procedure. It involves removing the damaged parts of the hip joint and replacing them with artificial components made of metal, ceramic or durable plastic.
This surgery is typically recommended when the joint is severely damaged by osteoarthritis, rheumatoid arthritis, fractures or other degenerative conditions. Unlike arthroscopy, which repairs or reshapes existing structures, replacement provides an entirely new joint surface.
Hip replacement is highly effective at reducing pain and restoring mobility. It is considered one of the most successful orthopaedic operations with many patients experiencing decades of improved quality of life after surgery.
Comparing the Two Procedures
Goals of Treatment
Hip arthroscopy focuses on preserving the natural joint by correcting structural problems or repairing damaged tissue. It is often recommended for younger or middle-aged patients with localised hip issues but relatively healthy joint surfaces.
Hip replacement, on the other hand, is designed to address widespread joint damage. It replaces the joint entirely, making it the preferred option for older patients or those with severe arthritis that cannot be managed conservatively.
Invasiveness
Hip arthroscopy is minimally invasive, involving small incisions and the use of a camera.
Hip replacement, on the other hand, is a larger operation that requires open access to the joint and removal of bone and cartilage.
Recovery
Recovery from hip arthroscopy is quicker in the short term, with many patients resuming light activities within a few weeks. However, full recovery and return to sports may still take several months.
Hip replacement requires a longer recovery, with rehabilitation focused on walking, strengthening and adapting to the artificial joint. That said, the long-term results of replacement often surpass those of arthroscopy in patients with advanced disease.
Longevity of Results
Because arthroscopy preserves the natural joint, outcomes depend on the underlying health of the hip. If arthritis is already present, relief may be temporary.
Hip replacement, on the other hand, generally offers more predictable, lasting results, with modern implants often lasting 15 to 20 years or more.
Who Might Benefit from Hip Arthroscopy?
- Labral tears or hip impingement without significant arthritis
- Localised cartilage damage
- Pain that limits activity but not caused by widespread joint degeneration
- Younger, active individuals seeking to preserve their natural joint
These patients often want to return to sports or high-impact activities, making joint preservation an appealing option.
Who Might Benefit from Hip Replacement?
- Patients with advanced osteoarthritis or rheumatoid arthritis
- Individuals whose pain persists despite medications, injections, or physiotherapy
- Older adults with severely reduced mobility and quality of life
- Cases where imaging shows extensive joint damage beyond repair
For these patients, replacement offers long-term pain relief and the chance to regain independence.
Which is Right For You?
Deciding between hip arthroscopy and hip replacement is not always straightforward. Factors such as age, activity level, severity of joint damage and long-term goals all play a role. An orthopaedic specialist will typically evaluate symptoms, physical examination findings and imaging results to recommend the most suitable option.
Furthermore, patients who wish to maintain a very active lifestyle may prefer joint-preserving surgery if appropriate, while those who prioritise long-term relief from debilitating pain may benefit most from a replacement.
If you are struggling with persistent hip pain, consulting an orthopaedic surgeon can help clarify which approach aligns best with your condition and lifestyle goals. For more information, please contact our orthopaedic clinic today.
