Can the seemingly simple act of walking, running, or even sitting comfortably be sabotaged by something unseen within your body? The intricate network of ligaments within your hip joint is the unsung hero, dictating your mobility and comfort, and their health is paramount to your active life.
The human hip, a marvel of biological engineering, is more than just a ball-and-socket joint. Its a complex system where the bones, muscles, and ligaments work in concert to facilitate a wide range of motion while providing stability and support. As noted, the stability of the hip joint is directly related to its muscles and ligaments. Among these, ligaments play a crucial, often underestimated, role. They act as the silent guardians, holding the joint together, preventing excessive movement, and allowing for smooth, fluid motion. The most notable ligaments in the hip joint are the iliofemoral ligament, which connects the pelvis to the femur at the front of the joint; the pubofemoral ligament; and the ischiofemoral ligament. The hip joint is surrounded by a strong fibrous capsule that forms a sleeve around the acetabulum and the neck of the femur. This capsule, along with the ligaments within, defines the boundaries of movement, preventing dislocation and protecting the delicate structures within.
The key ligaments that provide stability are critical. Shaped like a "Y", the iliofemoral ligament is crucial for maintaining an upright posture by limiting hyperextension. This is the strongest ligament in the body, capable of withstanding significant forces. The primary function of this ligament is to prevent hip hyperextension and external rotation in an upright position. In addition, it serves as a reinforcer of the anterior capsule. The pubofemoral ligament reinforces the anterior capsule, while the ischiofemoral ligament is the weakest of the four ligaments and consists of a triangular band of fibres that form the posterior hip joint capsule. The stability of the hip is increased by the strong ligaments that encircle the hip the iliofemoral, pubofemoral, and ischiofemoral ligaments. These ligaments completely encompass the hip joint and form the joint capsule, providing a robust barrier against injury and excessive movement.
Ligaments are fibrous structures that connect bones to other bones. They are not as elastic as tendons, which connect muscles to bones, and thus have a more limited ability to stretch. The hip joint is encircled with ligaments to provide stability to the hip by forming a dense and fibrous structure around the joint capsule. The ligaments adjoining the hip joint include the iliofemoral, pubofemoral, and ischiofemoral ligaments, along with the transverse acetabular ligament and the ligament of the head of the femur. Collectively, they play a vital role in the stability of the hip joint, ensuring that the bony components remain aligned and the joint functions correctly. Their role is often overlooked until something goes wrong.
Overstretching the ligaments of the hip capsule due to overuse or trauma can lead to a feeling of instability. Problems with the hip ligaments cause pain in and/or around the hip joint and reduced hip function. The delicate balance of the hip joint can be easily disrupted, leading to pain, reduced mobility, and, in severe cases, chronic instability. These devices, when used under professional guidance, can help in maintaining an optimal hip position, thereby reducing stress on the ligaments. Surgical intervention in cases where the ligament is completely torn, or if theres significant instability in the hip, surgery might be the most viable option. In addition to using PRP or BMAC to help heal the hip ligaments, we also look for associated injuries with the hip cartilage, labrum, tendons, and bones that we can also treat and help heal. Recovery from hip injuries is possible. Dont avoid the diagnosis of a hip ligament injury.
Understanding the specific ligaments within the hip joint is crucial. The capsular ligaments include the iliofemoral ligament (also known as the Y ligament of Bigelow), the pubofemoral ligament, and the ischiofemoral ligament. The iliofemoral ligament is the strongest ligament in the body; and its main function is preventing overextension. The ligaments of the hip joint act to increase stability. The only intracapsular ligament is the ligament of head of femur. It is a relatively small structure, which runs from the acetabular fossa to the fovea of the femur. This ligament contributes to the stability of the femoral head within the acetabulum, especially during internal and external rotation.

The ligaments of the hip joint can be divided into two groups: capsular ligaments and intracapsular ligaments. Capsular ligaments are intrinsic ligaments of the joint capsule; there are three capsular ligaments that play a key role in maintaining the integrity of the joint during various movements. Their primary function is hip abduction, notably resisting hip adduction when standing on one leg. (When standing on one leg, the bodys center of gravity is medial to the hip joint, such that without resistance, the hip joint would passively adduct, causing the pelvis to tilt. Isometric hip abduction force by the glutei keep the pelvis level. The hip joint movements are assisted by flexor, extensor, abductor and adductor muscles. Two ends of muscle continue as tendon. Tendons are attached to acetabulum and neck of femur adjacent to ligaments. Hip sprain occurs when ligaments supporting hip joints are overstretched or torn.
Within our hip anatomy, we have several ligaments that hold the bones of the hip together and provide stability to the joint. This ligament is the strongest in the body and helps to prevent overextension of the hip joint. The hip, like all synovial joints, is surrounded by a fibrous capsule, but is unique in that this capsule contains three thickenings which are interpreted as the ligaments of the hip. The three ligaments together all spiral around the femoral neck and head from posterior to anterior, such that they all become taut in extension and assist in the passive support of the joint during. The iliofemoral ligament is considered the strongest ligament of the body as it can support a traction up to 350 kg. It has a relevant role in the hip joint stability.
Generally, the hip's ligaments provide a slack region in mid-flexion, where the muscles can freely move the joint in internal rotation, external rotation, abduction, or adduction. Tightness of these ligaments and tendons can cause hip instability and pain. Strong and flexible ligaments and tendons provide structure to the hip, reducing strain on the joint, so most hip osteoarthritis therapies will including stretching and strengthening of these structures. A synovial membrane encapsulates the entire hip. Ligament stability is poorly understood by most physicians and oftentimes missed. We have successfully treated pelvic ligaments injuries through precise injections of both PRP and stem cells. Within the hip joint, only one ligament resides; the ligamentum teres, or ligament of head of femur. A triangle-shaped ligament, the ligamentum teres supplies blood to the femoral head with help from the obturator artery, and branches from the acetabular fossa to the fovea of the femur.
Labral tears often result from hip ligament injury, or they can happen concordantly with hip ligament injuries. A common mechanism for hip labral tears is when the patient sits a lot, so the butt muscles become weak. Hip joint capsular ligaments serve a fundamental role in balancing functional mobility and joint stability. The ischiofemoral ligament limits internal rotation and hip adduction with flexion. Iliofemoral ligament (Y ligament of Bigelow): This is the strongest ligament in the body. The hip joint is reinforced by a capsule and strong ligaments; the annular ligament of the hip, transverse acetabular, iliofemoral, pubofemoral and ischiofemoral ligaments.
Hip pain, however, can stem from various sources, and tendonitis is a common culprit. The most common symptom of hip tendonitis is hip pain that happens gradually. It can also cause tenderness at the point in the hip where the tendon is. People with iliopsoas tendonitis often feel pain in the front of their hip. If hip tendonitis goes untreated, the pain can get worse over time. When they dont and a condition like tendonitis crops up, youre often left with hip pain and mobility issues. To help you figure out whether your hip problem might be related to a tendon issue, the resident hip specialist here at Western Orthopaedics Dr. Brian White outlines a few basics about hip tendonitis here.
