Minimally invasive procedures in which small incisions are made to repair tears of the labral (cushioning structure along the rim of the hip socket), trim torn articular cartilage, or reshape bone deformities in people with femoroacetabular impingement, a form of tendinitis, are available. Total hip replacement is an operation that removes the arthritic ball of the upper thigh bone as well as the damaged cartilage from the hip socket. This surgery creates a new weight-bearing surface and a smoothly functioning joint to relieve pain and allow you to return to daily activities.
Robotic-assisted hip arthroplasty
Total hip replacement using a surgical robot may be a treatment option for people living with degenerative hip joint disease and provides a customized surgical service that caters to your specific hip characteristics.
During the procedure, orthopedic surgeons use a computed tomography (CT) scan of the damaged hip to construct a three-dimensional model of your joint. The robot interprets the information provided by the CT scan, providing tactile, visual and auditory feedback along with real-time data and guides the surgeon to the precise placement of the artificial hip joint prosthesis. The technology provides accuracy and precision, smaller incisions, improved safety and risk to adjacent tissues.
If you are a good candidate, you will have a CT scan of your hip in advance of the surgery date, which is used by your surgeon to create your unique surgical plan for optimal implant placement.
Mini-incision hip replacement
Minimally invasive surgery involves two smaller incisions, compared to standard hip replacement surgery that uses one long incision. In the minimally invasive procedure, small instruments allow the surgeon to move aside muscles, ligaments, and tendons rather than cut through them, greatly reducing discomfort after surgery and rehabilitation time. There are many approaches to total hip replacement, and Main Line Health offers both the traditional posterior hip replacement (incision made behind the major walking muscles) and the more rare anterior hip replacement procedure (incisions made on the front of the hip area to access the hip). Both techniques involve replacing the hip joint with a prosthetic implant to treat severe physical joint damage from arthritis or a hip fracture. Total hip replacement may be a good option if arthritis or a prior injury has damaged your joint, affecting its function even before the fracture. There are many approaches to total hip replacement, and Main Line Health offers both the traditional posterior hip replacement (incision made behind the major walking muscles) and the more rare anterior hip replacement procedure (incisions made on the front of the hip area to access the hip).
At Lankenau Medical Center, direct anterior total hip replacement is performed on The Hana®, a state of the art surgical table that enables an incision at the front of the hip without disturbing the gluteal muscles.
Partial hip replacement
If the ends of the broken bone are displaced or damaged, your surgeon may remove the head and neck of the femur and install a man-made replacement (prosthesis). Hemiarthroplasty is a surgical procedure which replaces one half of the joint with an artificial surface and leaves the other part in its natural (pre-operative) state. The procedure is performed by removing the head of the femur and replacing it with a man-made prosthesis. The procedure is recommended only for elderly and frail patients, due to their lower life expectancy and activity level. This is because with the passage of time the prosthesis tends to loosen or to erode the acetabulum.
