When Bangladeshi patients come to me with long-standing hip pain, the question is often not only “Do I need surgery?” It is also, “If I do need hip replacement, which type is better for me?” In Dhaka, families also think about recovery time, safety, cost, and whether the patient can return to prayer, walking outside, household work, or job duties.
Hip replacement is not one single operation. There are different implant designs and different surgical decisions, and the “best” choice depends on diagnosis, age, bone quality, activity level, and the pattern of damage inside the hip.
This article is educational. It cannot replace an individualized surgical recommendation, because that decision depends on X-rays, clinical examination, and the patient’s functional goals.
What doctors mean by “partial” and “total” hip replacement
People often hear “partial” and “total” and assume one must be better than the other. In reality, they are designed for different situations.
Total hip replacement (THR)
In total hip replacement, both sides of the hip joint are replaced:
- the femoral head (ball) is replaced with a metal or ceramic ball on a stem
- the acetabulum (socket) is replaced with a cup and liner
This is the most common type of hip replacement for advanced hip arthritis and many other joint-destroying conditions.
Partial hip replacement (hemiarthroplasty)
In partial hip replacement, the femoral head is replaced, but the socket is not replaced. This operation is most commonly used for certain hip fractures in older patients, where the socket cartilage is still acceptable and the main problem is the broken femoral head/neck.
So before comparing partial vs total hip replacement, we first have to ask: what is the diagnosis?
The most important factor: diagnosis
In my practice, I start by clarifying whether the patient has:
- advanced osteoarthritis (wear-and-tear arthritis)
- avascular necrosis (loss of blood supply to the femoral head)
- inflammatory arthritis (such as rheumatoid arthritis)
- hip fracture (especially neck of femur fracture)
- previous hip surgery or deformity
For most patients with severe arthritis, a total hip replacement is usually the appropriate concept, because the socket cartilage is also damaged. For many displaced hip fractures in elderly patients, a partial replacement may be considered, depending on activity, cognition, and socket condition.
Which is “better” depends on goals and risks
Patients often want a simple answer. But “better” can mean different things:
- better pain relief
- better long-term durability
- lower complication risk
- lower cost
- faster mobility
The right choice balances these goals realistically.
Typical reasons total hip replacement is chosen
Total hip replacement is often preferred when:
- there is significant cartilage damage in the socket
- pain is long-standing and affects daily life
- stiffness and limited range of motion are present
- the patient is relatively active and expects higher function
In many arthritis cases, partial replacement would not solve the problem because the socket surface remains damaged, and pain can continue.

Partial hip replacement is often considered when:
