Partial Hip Replacement (Hemiarthroplasty): What You Should Know

Dealing with hip pain from a fracture or arthritis can really slow you down. When painkillers, therapy, and other treatments don’t do enough, your doctor might suggest a partial hip replacement, also called hemiarthroplasty. It’s a surgery that helps you move better and live with less pain — and it’s not as complicated as it might sound.

What Is Partial Hip Replacement?

In simple terms, partial hip replacement means the surgeon removes only the ball part of your hip joint (that’s the top of your thigh bone) and replaces it with an artificial one. The socket part of your hip usually stays just the way it is — unless it’s damaged too, but most of the time it’s still fine.

It’s mostly done for:

Femoral neck fractures — a common break in the bone near the hip, often seen in older adults after a fall

Osteoarthritis — where the joint wears out over time, causing stiffness and pain

Rheumatoid arthritis — when the immune system attacks your joints, leading to damage

The Procedure

Here’s a quick rundown of what happens:

Pre-Surgical Preparation: You’ll get imaging tests like X-rays or maybe an MRI. Your doctor needs to check how bad the damage is.

Anesthesia: You’ll either be asleep under general anesthesia, or you’ll be awake but numb from the waist down with spinal anesthesia.

Surgical Approach: They make a cut near your hip, take out the damaged femoral head, and put in a new metal or ceramic ball that fits into your thigh bone.

Closure and Recovery: After placing the implant, they close the incision with stitches or staples and move you to recovery.

The whole procedure usually takes about 1–2 hours.

Benefits of Partial Hip Replacement

Partial hip replacement has a few clear benefits:

It’s less invasive than a total hip replacement.

It preserves more of your natural bone, especially the socket part.

Recovery tends to be faster because the body has less to heal.

Mobility improves, and most people can walk and move around with a lot less pain afterward.

Recovery and Rehabilitation

Recovering from surgery takes some time, but most patients do pretty well. Here’s how it usually goes:

Hospital stay: You’ll probably stay in the hospital for 2–4 days. They’ll get you up and walking — even if it’s just a few steps — the day after surgery.

Physical therapy: You’ll start working with a physical therapist pretty quickly. Therapy focuses on getting your strength and balance back.

Home care: You might use a walker or crutches at first. It’s normal to need a little help with daily things like getting dressed or cooking.

Gradual Return to Activity: Over a few weeks or months, you’ll slowly get back to doing the things you enjoy.

Every person heals differently, but most people feel a lot better within 3 months.

Potential Risks and Considerations

Like any surgery, there are some risks involved:

Infection (which is usually treated with antibiotics if caught early)

Blood clots in the legs (you’ll get medication or compression socks to prevent them)

Dislocation of the new joint (not very common but possible)

Implant wear over the years — sometimes the prosthetic can wear down and need to be replaced later

Your surgeon will go over all these risks with you before surgery.

Who is a Candidate for Partial Hip Replacement?

Partial hip replacement is usually a good option if:

Only the ball part of your hip is damaged — the socket is still healthy

You have chronic pain that hasn’t gotten better with other treatments

You’re in good enough health to handle surgery and the rehab afterward

Conclusion

If you’re living with constant hip pain that’s keeping you from doing what you love, a partial hip replacement might be the solution. It’s a straightforward procedure that helps a lot of people get back on their feet — sometimes literally within days. Talk it over with your orthopedic surgeon in Thane and find out if it’s the right choice for you.

No one should have to live in pain when there are good options available.
