Osteoarthritis of Hip
Osteoarthritis, also called degenerative joint disease is the most common form of arthritis. It occurs most often in older people. This disease affects the tissue covering the ends of bones in a joint (cartilage). In a person with osteoarthritis, the cartilage becomes damaged and worn out causing pain, swelling, stiffness and restricted movement in the affected joint. Although osteoarthritis may affect various joints including hips, knees, hands, and spine, hip joint is most commonly affected. Rarely, the disease may affect the shoulders, wrists and feet.
Osteoarthritis is characterized by damaged articular cartilage, cartilage lining the hip joint. Advanced age is one of the most common reasons for osteoarthritis of hip.
Femoroacetabular Impingement (FAI)
The hip is a ball-and-socket joint which is lined by cartilage and normally moves freely. Femoral acetabular impingement (FAI) is due to ‘impingement’ or abnormal contact between the ball (femoral head) and socket (acetabulum). This is commonly the result of either an abnormally shaped ball (cam lesion), or socket (pincer lesion) or both (mixed cam and pincer). When the abnormally shaped ball or socket comes into contact with other structures (‘impinges’), it can result in damage to the cartilage along the rim of the socket (the labrum) or to the cartilage lining the socket (the articular cartilage). Tears of the hip ligament (known as the ligamentum teres) may also result.
What is a Labral Tear?
The hip is a ball-and-socket joint, lined by cartilage, which normally moves freely. The labrum is a specialised cartilage that lines the rim of the hip socket. It deepens the socket, protects the underlying cartilage lining the joint (ie. the articular cartilage) and forms a seal around the ball (femoral head). If abnormal contact between the ball (femoral head) and socket (acetabulum) occurs, this direct contact to the labrum can result in a tear (ie. a labral tear). If you have a labral tear, you actually have femoral acetabular impingement (FAI) with a labral tear.
What is Hip Arthroscopy?
Hip arthroscopy is a minimally invasive surgical procedure performed through 2 or 3 small 5-10mm incisions (ie. key hole surgery) using an advanced HD camera and special instruments to visualise and work inside and around the hip joint. A specially designed hip traction table is used to allow access into the hip joint. Complications are not common but can occur. Prior to making any decision to have surgery, it is important that you understand the potential risks so that you can make an informed decision on the advantages and disadvantages of surgery.
Anterior Hip Replacement
What is an anterior hip replacement?
A hip replacement is an operation performed to replace a worn-out hip joint. The diseased joint and bone is removed and a new ball and socket joint is inserted. There are many different types of artificial joints available, all made from different materials and offering different bearing surfaces. Your surgeon will often discuss the options available and what his or her preferences are. When having a hip replacement, a very important consideration is the method used by your surgeon to insert the artificial joint.
Hip Labral Tear
Labrum is a ring of strong fibrocartilaginous tissue lining around the socket of the hip joint. Labrum serves many functions where it acts as shock absorber, lubricates the joint, and distributes the pressure equally. It holds the head of the femur in place and prevents the lateral and vertical movement of the femur head with in the joint. It also deepens the acetabular cavity and offers stability against femoral head translation.
Labral tear may be caused by trauma, femoroacetabular impingement (FAI), hip hypermobility, dysplasia, and degeneration.
Gluteus Medius Repair
Gluteus medius is one of 3 muscles in the buttocks and is situated on the outer surface of the hip. The function of the gluteus medius is to assist with pelvis stability, hip abduction, along with internal and external rotation of the hip. Tears of the gluteus medius usually occur where the tendon inserts at the greater trochanter, causing lateral hip pain.
Tears of the gluteus medius can occur due to traumatic injury or degenerative conditions such as tendinopathy (chronic inflammation of the gluteus medius tendon). Gluteus medius tears cause pain and weakness on the affected side of the hip.
‘Bikini’ incision Hip Replacement
A ’bikini’ incision hip replacement refers to the skin incision that is made in order to perform a hip replacement. The scar is cosmetically and visually pleasing as it is hidden in the groin skin crease. The added advantage is that the the hip replacement is performed through the anterior approach.
