Key Takeaways
- Total and partial hip replacement surgeries both relieve hip pain, but differ in how much of the joint is replaced.
- Total hip replacement treats advanced arthritis or damage by replacing both the ball and socket of the joint.
- Partial hip replacement replaces only the ball portion of the joint and is often used for specific types of hip fractures.
- Choosing the right procedure depends on your diagnosis, lifestyle, and overall joint condition.
- Dr. Timothy J. Williams, a board-certified orthopedic surgeon in Noblesville and Terre Haute, IN, offers personalized evaluations to determine which surgical option will best restore your mobility and quality of life.

Understanding the Difference Between Total and Partial Hip Replacement
Total Hip Replacement (THR)
Total hip replacement, also called total hip arthroplasty, is designed to relieve pain and improve joint function when both the femoral head (the “ball”) and the acetabulum (the “socket”) are damaged.
During surgery, Dr. Williams removes the diseased bone and cartilage and replaces them with durable, biocompatible components that create a smooth, natural-feeling joint.
This procedure is most often recommended for patients with:
- Advanced arthritis (osteoarthritis, rheumatoid, or post-traumatic)
- Avascular necrosis or bone collapse
- Severe joint degeneration that limits movement and comfort
Dr. Williams performs total hip replacement using minimally invasive, robotic-assisted techniques and Enovis joint replacement systems, enhancing surgical precision and helping shorten recovery time.
Partial Hip Replacement (PHR)
Partial hip replacement, sometimes called hemiarthroplasty, replaces only the femoral head while leaving the socket intact.
It’s typically performed when damage is confined to one side of the joint, such as:
- Hip fractures where the socket remains healthy
- Localized degeneration of the femoral head
- Older adults for whom full joint replacement may not be necessary
By preserving healthy bone and cartilage, partial hip replacement can reduce operative time and recovery demands. However, because it does not resurface the socket, it is not ideal for patients with arthritis affecting the entire joint.
Comparing Total vs. Partial Hip Replacement
| Feature | Total Hip Replacement | Partial Hip Replacement |
|---|---|---|
| Replaces | Both the ball (femoral head) and socket (acetabulum) of the hip joint are replaced with durable prosthetic components. | Only the ball (femoral head) is replaced; the natural socket remains intact. |
| Ideal For | Patients with advanced arthritis, degenerative joint disease, or joint damage from trauma. | Patients with isolated femoral head fractures or localized damage, but a healthy socket. |
| Surgical Time | Slightly longer (typically 1.5–2 hours), due to the complete joint reconstruction. | Usually shorter (under 1.5 hours) since only part of the joint is replaced. |
| Longevity of Results | Designed for long-term durability, often lasting 15–25 years or more, thanks to advanced materials like ceramic and titanium. | May require revision surgery if arthritis or socket degeneration progresses. |
| Mobility Restored | Provides full joint function, smoother motion, and better alignment, allowing patients to return to daily and recreational activities. | Improves mobility and reduces pain, though the range of motion may be limited over time due to natural socket wear. |
| Typical Patients | Active adults or seniors with chronic arthritis or degenerative joint conditions who seek long-term relief. | Older adults with hip fractures and minimal pre-existing arthritis. |
| Recovery & Rehabilitation | Patients typically begin physical therapy within 24 hours after surgery. With Dr. Williams’s minimally invasive approach, recovery averages 3–6 months for full function. | Recovery may be faster initially, but long-term outcomes depend on whether arthritis develops in the socket later. |
Both procedures are safe and effective when performed by an experienced orthopedic surgeon. The best choice depends on the condition of the joint and your personal goals for mobility and lifestyle.
How Dr. Williams Determines Which Option Is Right for You
Dr. Williams takes a comprehensive, individualized approach to joint replacement care. During your consultation, he will:
- Review your medical history and current symptoms
- Conduct a physical exam to assess the range of motion and stability
- Order X-rays or MRI scans to visualize the extent of joint damage
Based on this evaluation, Dr. Williams will recommend either total or partial hip replacement, explaining the benefits, recovery expectations, and outcomes of each. His use of robotic-assisted technology and precision-guided surgical planning ensures every procedure is tailored to your anatomy for optimal results.
What to Expect During Recovery
Whether you undergo a total or partial hip replacement, recovery is a collaborative process between you, Dr. Williams, and his rehabilitation team.
Early Phase
- Most patients begin standing and walking within 24 hours after surgery.
- Pain is managed with medication, cold therapy, and gradual movement.
Rehabilitation
- Physical therapy begins early to restore strength and flexibility.
- Movement precautions are emphasized to protect the healing joint.
Long-Term Results
- Most patients return to normal daily activities within a few months.
- With proper care, both total and partial replacements can provide years of pain-free movement and improved quality of life.

Frequently Asked Questions
What is the main difference between total and partial hip replacement?
A total hip replacement replaces both the ball and socket of the joint, while a partial replacement replaces only the ball. Total replacement is more common for arthritis; partial is often used for fractures.
How do I know which type I need?
Dr. Williams performs a detailed evaluation, including imaging and range-of-motion testing, to determine which procedure best addresses your pain and goals.
Is recovery time different?
Partial hip replacement sometimes allows a slightly shorter recovery, but rehabilitation and mobility exercises are essential after both procedures.
Are both surgeries minimally invasive?
Yes. Dr. Williams uses tissue-sparing and robotic-assisted techniques for both, designed to promote accuracy and comfort.
How long will my new hip last?
With proper care and follow-up, hip replacements are designed for long-term durability and function, allowing years of pain-free movement.
