Dual Mobility Hip Replacement
Dual mobility hip replacement is a high performance hip replacement implant and is more complex than standard hip replacement.
The benefits of dual mobility hip replacement are:
- Fewer postoperative restrictions
- More stability
- More natural hip feel
- Unrestricted range of motion
- Unrestricted activity including high impact capability
- Very low risk of dislocations
Dual Mobility Hip Replacement is suitable for patients who require a very stable hip with a high range of movement, e.g. as required in the martial arts, yoga, Pilates etc.
Dual Mobility Hip Replacement Outcomes
More Movement – allows patients to perform a high level of activity without risk of dislocation including running, skiing, martial arts, golf, tennis, surfing, climbing and almost anything that their general fitness will allow.
Immediate Return – immediate full weight bearing and range of motion exercises. Most patients leave hospital after 2-4 days. Some patients transfer to rehab for hydrotherapy.
Fewer Limits – Normal postoperative hip precautions are unnecessary after dual mobility hip replacement. Sitting in low chairs, crossing legs and forward bending are all safe and acceptable activities after dual mobility hip replacement.
Safe Movement – Dual Mobility hip replacements are capable of a much greater range of safe movement than standard hip replacements.
Modular Design – Dual Mobility hip replacements are also modular, meaning that a part of the hip replacement can be replaced if necessary. Like a car’s brake pad, the femoral head which is the mobile part of the hip, can be replaced if it wears out after years of use.
Rehab Course – The decision on whether to go to rehab post-operatively is made according to the patient’s progress, taking into account their wishes and preferences.
Technology – The dual mobility implant employs a low wear, high range of motion implant system.
Dual mobility hip replacement is ideally suited to a minimally invasive surgical method and can be implanted using the direct anterior or minimally invasive posterior surgical approaches.
Is Dual Mobility Hip Replacement Proven?
The procedure has been used for over 30 years. The peer reviewed literature shows excellent long term results.
With ongoing material improvements in ceramic and polyethylene technology it is expected the dual mobility implant's performance and durability will continue to improve.
Of course, like everything in life that moves, there is a natural wear rate that applies to all hip implants. Clocking up the miles on the road generates wear. This is inevitable and applies to all hip and knee replacements. As the dual mobility system is modular the femoral head can be replaced without revising the rest of the hip which means no bone resection is required. Replacement of the dual mobility femoral head, if required, is a relatively minor procedure.
