Partial Hip Replacement vs. Total Hip Replacement Surgery
If chronic hip pain has limited your mobility, you’re not alone—more than 300,000 hip replacement surgeries are performed in the U.S. every year. Medical terminology can be confusing when you’re trying to understand different treatment options, however, and you may have found yourself wondering what the difference is (if any) between a hip replacement vs. a total hip replacement.
This blog breaks down the anatomical and surgical differences between a partial procedure and a total hip replacement surgery. You’ll learn about
- The basic anatomy of the hip joint
- The evolution of modern surgical techniques
- Specialized procedures like the SMART Total Hip
- The recovery timeline you can expect after surgery
Understanding Hip Joint Anatomy
To understand hip joint replacement, you need to understand the basic anatomy of the hip joint. The hip operates as a ball-and-socket mechanism. The femoral head, which is the ball at the top of the femur or thigh bone, fits securely into the acetabulum. The acetabulum functions as the hip socket in the pelvis.
Conditions such as osteoarthritis and rheumatoid arthritis wear away the protective cartilage between these bones. This deterioration leads to bone-on-bone friction. Patients then experience severe hip pain and a significant loss of mobility.
Defining the Surgical Options
Orthopedic surgeons offer several treatment options depending on the extent of the joint damage.
Hip Resurfacing
Hip resurfacing preserves the natural bone by capping the femoral head with a metal covering rather than removing it entirely. The Birmingham hip resurfacing procedure is typically prescribed for young, active patients facing premature arthritis. It provides pain relief while maintaining the structural integrity of the femur.
Partial Hip Replacement (Hemiarthroplasty)
Partial hip replacement is a surgical procedure that only replaces the femoral head. Orthopedic surgeons typically use hemiarthroplasty to treat hip fractures in elderly patients. In these specific cases, the hip socket remains healthy and does not require modification.
Total Hip Replacement (Total Hip Arthroplasty)
A total hip replacement, or total hip arthroplasty, addresses comprehensive joint damage. This total joint replacement removes both the damaged ball and the damaged socket. The surgeon replaces these anatomical structures with a durable prosthesis to restore fluid movement.
Factors Influencing the Surgical Decision
An orthopedic surgeon evaluates the specific severity of the joint damage before recommending a procedure. Severe arthritis typically necessitates a complete replacement, while a localized fracture may require only a partial repair.
Patient demographics also play a crucial role in surgical planning. Older patients and active individuals require different approaches based on their specific activity level and overall health. A tailored approach increases the likelihood of long-term success.
Advanced Surgical Approaches
Surgical techniques have evolved significantly over the past decade. Traditional methods, such as the posterior and anterior approaches, require distinct incisions. Modern, minimally invasive techniques prioritize a quicker recovery.
Bikini Hip Replacement
The Bikini Hip Replacement is an advanced direct anterior approach that utilizes a discreet, 3- to 4-inch horizontal incision along the natural “bikini line” or groin crease. The procedure avoids cutting muscles while accessing the joint, significantly reducing soft tissue trauma and post-operative pain. Because the incision follows the skin’s natural grain, it results in a nearly invisible scar. Patients also typically experience a faster recovery,
SMART Total Hip Replacement
Developed by Dr. Vladimir Alexander here at Alexander Orthopaedics, the SMART Total Hip Replacement reduces standard surgical risks. Our data shows that this technique decreases the hip dislocation rate. It preserves the joint capsule and lowers the chance of nerve damage compared to standard methods. Less tissue trauma translates to better patient outcomes.
Materials and Fixation
Modern implants utilize advanced materials to mimic natural joint function. These components include titanium stems, ceramic or metal balls, and specialized polyethylene liners.
Surgeons use two primary fixation methods. Cemented components rely on medical-grade bone cement for immediate stability. Uncemented implants feature a porous surface. This design allows natural bone to grow into the prosthesis over time, creating a permanent biological bond.
Potential Risks and Complications
All surgeries carry inherent risks. Patients undergoing any kind of joint replacement surgery, be it partial or total, should be aware of potential complications, including infection, blood clots, and leg-length discrepancy.
Here at Alexander Orthopaedics, we employ specialized procedures to mitigate these risks through advanced planning and execution. Recurrent instability or implant wear over decades can sometimes necessitate a revision surgery. Routine follow-ups and X-ray evaluations help monitor the health of the prosthesis.
Pain Relief and At-Home Rehabilitation
The immediate post-operative timeline focuses on safe, early movement. Patients begin walking with assistance hours after waking up and can recover in the comfort of their own homes. In fact, the Alexander Outpatient Advantage often allows patients to avoid hospital stays entirely.
Physical therapy plays an essential role in restoring the patient’s range of motion. Targeted exercises rebuild the muscles surrounding the hip to ensure long-term stability.
Patients routinely experience life-changing results. Mary Frances Blackard shared her experience: “I am now 8 weeks post-op on my second hip replacement, and I am quite pleased with the progress... Thank you, Dr. Alexander, for giving me my life back!”

FAQs about Hip Replacement
When Is Hemiarthroplasty Recommended Over Total Hip Replacement?
Surgeons utilize hemiarthroplasty primarily for traumatic hip fractures in elderly populations where the socket remains undamaged. Replacing the femoral head and leaving the natural socket intact keeps the procedure shorter and less invasive, which can be helpful for patients who may not tolerate a longer, more complex total replacement.
When Should Hip Replacement Surgery Be Avoided?
Patients with active infections or severe medical instability face contraindications and should avoid this surgical procedure until their health stabilizes. Surgery may also be delayed for individuals with insufficient bone mass to support an implant or those whose pain can still be effectively managed through conservative, non-surgical treatments.
What is the 90-Degree Rule with Hip Replacement?
The 90-degree rule is a traditional post-operative precaution advising patients not to bend the hip past a right angle to prevent the new joint from dislocating during the healing process. While this was once standard for all patients, modern techniques like the direct anterior approach and SMART total hip replacement often loosen or eliminate this restriction entirely due to superior muscle preservation and increased joint stability.
Who Needs a Hip Revision Surgery?
Patients experiencing implant loosening, significant component wear, or recurrent dislocations may require a revision surgery to replace a failing or aged prosthesis.
