Reverse hip replacement systems, also known as reverse total hip arthroplasty, is a type of surgical procedure that reverses the natural anatomy of the hip joint.
The reverse hip replacement procedure differs from traditional hip replacement and is generally recommended in patients with complex hip problems that conventional hip replacement cannot treat properly.
In this article, we will be discussing in detail about reverse hip replacement systems.

What is reverse total hip arthroplasty?
A company known as Hip Innovation Technology (HIT) introduced and tested the HIT Reverse Hip Replacement System (Reverse HRS).
The Reverse HRS is a metal-on-polyethylene type of reverse geometry hip prosthesis designed to improve the stability of the hip joint at extended ranges of motion and also reduce the risk of dislocation.
It involves the use of a prosthetic design that reverses the natural anatomy of the hip joint.
Unlike traditional hip replacements, which mimic the natural ball-and-socket joint with a metal ball fitting into a plastic socket, reverse hip replacements use a concave component on the femur (thigh bone) and a convex component on the pelvis.
What are the parts of the reverse total hip arthroplasty?
A reverse hip replacement systems consists of the following components:
- Acetabular Component: This is a convex (ball-like) part that attaches to the pelvis.
- Femoral Component: This is a concave (cup-like) part that attaches to the femur.
- Liner: This part is inserted into the femoral component, helping in the smooth movement between the components.
When is reverse total hip arthroplasty indicated?
Reverse hip replacements is usually recommended in the following cases:
- Severe damage of the hip joint: It is indicated when the hip joint is severely damaged and is accompanied by extensive bone loss or deformity that cannot be treated by conventional hip replacements.
- History of failed hip surgeries: Patients who have undergone multiple hip surgeries without success may undergo a reverse hip replacement procedure.
- Complex fractures: Traditional hip replacements may not be recommended in complex bone fracture cases. ( Know more about- What is Bone Fracture ? )
- Severe type of osteoarthritis or rheumatoid arthritis: Patients with severe conditions of joint inflammation may undergo a reverse hip replacement. ( Know more about- Home Remedies for Arthritis )
- Hip joint infections: Some types of infections could lead to extensive damage to the hip joint structure and may need a reverse hip replacement procedure.
What is the preparation needed for reverse total hip arthroplasty?
The following are the preparation steps for reverse hip replacement:
- Diagnostic tests: The patient is physically examined by the doctor and certain diagnostic tests are recommended, like blood tests and imaging tests including X-rays, CT scans, and MRI scans. These tests help the doctor determine the extent of hip joint damage and also assess the health of the patient before the procedure.
- Implant Selection: Depending on the extent of joint damage, bone quality, and the patient’s anatomy, an appropriate implant is selected.
- Instructions to the patient: The following instructions are given to the patient before the procedure:
- The patient should inform the surgeon about any allergies that he or she may have.
- If the patient is taking any medications, the surgeon should be informed about them.
- The patient needs to quit smoking at least a few days before the procedure.
- The patient may be asked to stop taking blood-thinning medications at least a few days before the procedure.
- The patient is instructed not to eat or drink anything at least eight hours before the procedure.
What is the procedure for reverse total hip arthroplasty?
The procedure is generally carried out under the effect of general anesthesia, which means that the patient is made unconscious before the procedure. The following are the steps followed during the reverse hip replacement surgery:
- The surgeon will first make a large incision (open surgery) or several small incisions (minimally invasive surgery) using a posterior, anterior, or lateral approach to access the hip joint.
- The damaged cartilage is then removed and the acetabular bone (concave bone on the pelvis) is prepared to receive the convex component.
- The head of the femur bone is then removed and the femoral canal is then prepared to receive the concave component.
- The surgeon will then fix the convex component to the acetabulum and the concave component to the femur.
- A liner is then placed inside the concave component.
- The new joint is then brought together while ensuring proper alignment and stability.
- The incision site is then closed using staples or sutures.
What is post-operative care after reverse total hip arthroplasty?
The following are the steps for post-operative care after reverse hip replacement surgery:
- The patient will be monitored for complications like bleeding, infection, or dislocation immediately after surgery.
- The doctor will prescribe pain-relieving medications to manage the pain and discomfort after the procedure.
- The patient may need to use an assistive walking device like crutches or a walker in the initial recovery period.
- Physical therapy will be recommended after the surgery to slowly restore strength and mobility.
- Sufficient rest is advised for at least six weeks after the procedure.
- The patient is instructed to gradually increase mobility and activity levels.
- Complete recovery after surgery may take about six months or more.
- Long-term monitoring and evaluation of the patient by the surgeon is recommended.

What are the benefits of reverse total hip arthroplasty?
Reverse hip replacement systems have the following advantages compared to traditional hip replacement surgery:
- Improved stability
- Improved mobility
- Decreased risk of dislocation
- Suitable for complex cases where traditional hip replacements are not recommended
What are the risks of reverse total hip arthroplasty?
Reverse hip replacement systems could be associated with the following complications:
- Infection
- Fracture of the pelvis or femur
- Nerve injury
- Loosening of the prosthetic components over time
- Blood clot formation
- Dislocation (less common)
