Blog: Is Robotic Joint Replacement Surgery Safe?
Robot technology in hip and knee replacement surgery has created a lot of interest in Adelaide this year. There are two types of systems available or in development - large robotic arms that position the cutting tool for the surgeon and smaller hand held instruments that the surgeon positions while the robot retracts the cutting tool if it is in the wrong place.
Blog: Hip and Knee Replacements – What Really Matters?
For most patients the key question when having a hip or knee replacement is "How long will it last?"
It is now easy for Australian surgeons to answer this question thanks to the long term data on revision rates recorded by the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR). A revision is when an operation is performed to change one or more joint replacement components due to complications or other issues with the joint. The latest report shows that the average revision rate of hip and knee replacements at 10 years is approximately 5-10%. There is however a lot of variation depending on the implant used and the surgeon.
What's New in Knee Replacement?
For a patient considering knee replacement surgery, there are new developments under study which can help enhance their quality of life. These include:
- Use of Cementless parts that allow new bone to grow into a porous prosthesis and hold the parts in place, creating a biologic fixation
- Use of bioactive joint surfaces such as hydroxyapatite
Robotic Assisted Partial Knee Surgery
Robotic assisted partial knee surgery is an innovative alternative to the conventional surgical procedure in patients suffering from degenerative knee diseases such as osteoarthritis.
Minimally Invasive Total Knee Arthroplasty
Minimally invasive total knee arthroplasty is performed under sterile conditions in the operating room under spinal or general anesthesia. You will be lying on your back on the operating table with a tourniquet applied to your upper thigh to reduce blood loss.
Unicompartmental Knee Replacement
Unicompartmental knee replacement is a minimally invasive surgery in which only the damaged compartment of the knee is replaced with an implant. It is also called a partial knee replacement. The knee can be divided into three compartments: patellofemoral, the compartment in front of the knee between the knee cap and thigh bone, medial compartment, on the inside portion of the knee, and lateral compartment which is the area on the outside portion of the knee joint.
Computer Navigation for Total Knee Replacement
A total knee replacement surgery is the last resort to relieve pain and restore function in knee damaged by arthritis or an injury when non-surgical treatments do not relieve the condition.
Total Knee Replacement (TKR)
Total knee replacement, also called total knee arthroplasty, is a surgical procedure in which the worn out or damaged surfaces of the knee joint are removed and replaced with artificial parts.
Partial Knee Replacement
Unicompartmental knee replacement is a minimally invasive surgery in which only the damaged compartment of the knee is replaced with an implant. It is also called a partial knee replacement.
Revision Knee Replacement
Revision knee replacement surgery involves replacing part or all of your previous knee prosthesis with a new prosthesis. Although total knee replacement surgery is successful, sometimes the procedure can fail due to various reasons and require a second revision surgery.
Patellofemoral Knee Replacement
Patellofemoral knee replacement surgery may be recommended by your surgeon if you have osteoarthritis contained to the patellofemoral compartment and you have not obtained adequate relief with conservative treatment options.
