What is Hip Arthroscopy?
Hip arthroscopy is a minimally invasive surgical procedure performed through 2 or 3 small 5-10 mm incisions (i.e., 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. An anterior approach is a method of inserting the artificial joint through the front (i.e. anterior) without cutting any muscles or damaging nerves.
Hip Labral Tear
The labrum is a ring of strong fibrocartilaginous tissue lining around the socket of the hip joint. It 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 within the joint. It also deepens the acetabular cavity and offers stability against femoral head translation.
The anterior cruciate ligament (ACL) is an important major stabilising ligament within the knee. ACL sprains or tears are one of the most common knee injuries seen, particularly in those sports that involve twisting movements of the knee (such as football and netball). Unfortunately, ACL tears do not heal, often leading instead to instability of the knee. An ACL reconstruction is a surgical procedure to stabilise the knee by replacing (reconstructing) the torn ACL with another ligament graft. The graft is taken from tissues around the knee, such as the hamstring tendons or patella (knee cap) tendon. An artificial tendon graft may also be used. ACL reconstructions are usually performed arthroscopically (ie. key hole surgery).
Arthroscopic Meniscus Repair
Meniscus tear is the commonest knee injury in athletes, especially those involved in contact sports. A sudden bend or twist in your knees causes meniscal tear. This is a traumatic meniscus tear. Elderly people are more prone to degenerative meniscal tears as the cartilage wears out and weakens with age. The two wedge-shape cartilage pieces present between the thighbone and the shinbone are called meniscus. They stabilize the knee joint and act as “shock absorbers”.
Torn meniscus causes pain, swelling, stiffness, catching or locking sensation in your knee making you unable to move your knee through its complete range of motion.
Patient Matched Knee Replacement
When planning a total knee replacement for patient surgeons conventionally use 2 dimensional X-ray images and a transparent template to decide the size and placement of the artificial knee components. Other surgeons plan the size and placement of the components during the actual surgery with the use of measuring instruments.
A new technique is now available called Patient Matched Knee Replacement. This new approach to preoperative planning utilizes 3 dimensional MRI images (magnetic resonance imaging) to provide the surgeon with a customized, 3D template for every patient prior to surgery.
Knee arthroscopy is a minimally invasive surgical procedure performed through 2 small 5-10mm incisions (ie. key hole surgery) using an advanced HD camera and special instruments to visualise and work inside the knee joint. Almost all aspects of knee conditions can be treated successfully with knee arthroscopy.
Knee arthroscopy is a minimally invasive approach resulting in less tissue damage, less pain, less blood loss, and faster recovery and return of function.
Unicompartmental (Partial) Knee Replacement
What is a uni-compartmental knee replacement (UKR)?
Patients with osteoarthritis that is limited to just one part of the knee may be candidates for a uni-compartmental knee replacement (also called a “partial” knee replacement). Your knee is divided into three major compartments: the medial compartment (ie. the inside part of the knee), the lateral compartment (ie. the outside part), and the patellofemoral compartment (ie. the front of the knee between the kneecap and thighbone). In a uni-compartmental knee replacement, only the damaged compartment is replaced with metal and plastic. The healthy cartilage and bone in the remainder of the knee is left alone. The knee joint becomes worn-out most commonly as a result of osteoarthritis but may also result from other causes such as trauma or injuries, meniscal tears and overuse. The aim of a UKR is to relieve pain, restore function and movement, and improve quality of life. The potential benefits of a UKR over a total knee replacement (TKR) are: the smaller incision, less bone removal, less blood loss, faster recovery, better range of movement and a more “natural” feeling knee. The disadvantages of a UKR compared with a TKR include slightly less predictable pain relief, and the potential need for more surgery.
