The hip joint is one of the most powerful and complex structures in the human body, responsible for supporting your weight and powering your movement. But when pain or injury strikes, preserving the joint—not replacing it—is often the preferred option. Let’s explore the biomechanics of the hip, why cartilage preservation matters, and how AHI leads the way in joint-saving techniques.
Understanding the Biomechanics of the Hip Joint
The hip is a ball-and-socket joint, where the femoral head (ball) fits securely into the acetabulum (socket) of the pelvis. This design allows for a wide range of motion while bearing significant loads during everyday activities like walking, running, or climbing stairs. However, the joint must maintain proper alignment and balance to prevent uneven wear, instability, and degeneration.
When biomechanics are disrupted—through structural deformities like femoroacetabular impingement (FAI), a condition where abnormal bone shapes cause the hip bones to rub together, or labral tears, which involve damage to the cartilage ring that stabilizes the hip joint—hip function deteriorates.
The Critical Role of Cartilage Preservation
Cartilage health also impacts long-term joint function and overall mobility. Cartilage acts as the hip’s natural shock absorber, allowing for smooth and comfortable motion. Unfortunately, cartilage has a limited ability to heal once damaged. That's why preserving it is at the core of hip preservation strategies. At the American Hip Institute, we prioritize minimally invasive arthroscopic techniques that not only address the cause of pain but also preserve or restore cartilage health.
Advanced Techniques That Maintain Native Anatomy
Some of the key state-of-the-art techniques used are:
- Labral Repair and Reconstruction involves repairing or rebuilding the labrum, the cartilage ring that stabilizes the hip. Restoring its suction-seal function is crucial for maintaining joint stability and preventing further damage.
- Femoroplasty and Acetabuloplasty are procedures that reshape the femoral head or acetabulum to correct deformities caused by femoroacetabular impingement (FAI). By smoothing out bone irregularities, we reduce abnormal friction and protect the cartilage from wear.
- Capsular Management focuses on repairing or tightening the joint capsule—a key ligamentous structure that provides stability to the hip—helping to prevent joint laxity and maintain proper function.
- Cartilage Restoration may involve biologic treatments such as platelet-rich plasma (PRP), other orthobiologics, or microfracture techniques to stimulate cartilage healing and regeneration, supporting long-term joint health.

FAQs
Q1: What is hip preservation surgery and who is it for?
Hip preservation surgery refers to a range of minimally invasive procedures designed to correct structural problems, repair damaged tissue, and protect cartilage health — all while maintaining the patient's natural joint rather than replacing it. It is most appropriate for younger and active patients experiencing hip pain from conditions like femoroacetabular impingement, labral tears, or early cartilage damage, where intervention can restore function and prevent long-term joint deterioration.
Q2: Why is cartilage preservation important in hip treatment?
Cartilage acts as the hip's natural shock absorber, enabling smooth and pain-free movement under significant load. Because cartilage has a very limited ability to heal once damaged, preserving what remains is critical to maintaining long-term joint function and avoiding the need for hip replacement. Minimally invasive techniques that address the underlying cause of damage while protecting or restoring cartilage health offer the best chance of sustained mobility and performance.
Q3: What is femoroacetabular impingement and how is it treated?
Femoroacetabular impingement (FAI) occurs when abnormal bone shapes on the femoral head or acetabulum cause the hip bones to rub together, disrupting normal joint mechanics and damaging cartilage over time. It is commonly treated with arthroscopic procedures including femoroplasty and acetabuloplasty, which reshape the bone to eliminate abnormal friction, relieve pain, and protect the joint from progressive wear.
Q4: What is labral repair and why does it matter for hip function?
The labrum is a ring of cartilage that stabilizes the hip joint by creating a suction seal between the femoral head and the socket. When torn, this seal is disrupted, leading to instability, pain, and accelerated cartilage wear. Labral repair or reconstruction restores this stabilizing function, reduces mechanical stress on the joint, and is a cornerstone of hip preservation surgery for both athletes and active adults.
Q5: Can biologics like PRP help preserve hip cartilage?
Yes. Biologic treatments such as platelet-rich plasma (PRP) and other orthobiologic therapies can support cartilage healing and regeneration by delivering growth factors and anti-inflammatory agents directly to the damaged tissue. When used as part of a comprehensive hip preservation strategy — alongside structural corrections like labral repair or bone reshaping — biologics offer an additional layer of support for long-term cartilage health and joint function.
