Hip Replacement Medically reviewed by Thomas D. Ferro, M.D. in Carrollton, TX

Carrollton hip replacement with a personalized 3D plan and a same-day trip home. If you live in Carrollton or nearby Farmers Branch, Addison, Coppell or Lewisville, NanoHip™ offers hip replacement that skips the hospital stay. Your surgical plan is drawn up in 3D from your own CT scan before your procedure date. During surgery, your surgeon spares the surrounding muscles wherever possible, and you're kept comfortable with spinal anesthesia and sedation instead of general anesthesia. Within a few hours, most patients are walking, and by that evening they're resting at home.

A Smarter Hip Replacement for Carrollton

NanoHip™ surgeons have more than 5,400 hip replacements to their names, and their patients regularly:

Walk on their new hip within hours of the procedure
Are discharged home around two hours after surgery
Return to the sports and recreation they love without restrictions

Your implant is planned on a 3D reconstruction of your hip from your CT scan, with its size, position and alignment settled before you ever enter the operating room.

How NanoHip™ Stands Apart from Traditional Hip Replacement

Four distinctions separate NanoHip™ from a traditional hip replacement. Bring each of them up when you speak with prospective surgeons.

A blueprint built from your CT scan

Our biomedical engineers create a 3D reconstruction from your CT scan and use it to size your cup and stem, determine their placement, and plan your leg length and offset. The completed blueprint goes to your surgeon for review and approval before surgery.[3]

Home the same day, under spinal anesthesia

The research is reassuring. Pooling 20 studies and over 580,000 cases, one meta-analysis found that outpatient hip replacement produced complication and readmission rates comparable to inpatient surgery.[6] A national analysis of more than 380,000 joint replacements also showed spinal anesthesia was linked to lower 30-day mortality and fewer complications than general anesthesia.[5] You'll go home to Carrollton on the day of your surgery.

A gentler path to the joint

Rather than cutting muscle, NanoHip surgeons travel between muscle groups to reach the hip. Your 3D reconstruction gives your surgeon a clear view of your anatomy, so the minimally invasive approach is chosen to fit you, not to fit a slogan.

Implants with established registry records

Every implant NanoHip™ uses is FDA-cleared and has an established history in national joint registries. The customization happens in your plan; the implant and its materials are well proven.

The NanoHip™ Procedure, Explained

NanoHip™ hip replacements are planned in three dimensions and performed as outpatient surgery. You'll begin moving your new hip on surgery day and spend your recovery in the comfort of home. Our surgeons treat people who are determined to stay active, and that goal guides every plan they build. Hip instability leads to more revision surgeries in the U.S. than any other cause.[2]

To reduce that risk, our biomedical engineers and surgeons create and review your plan long before your operation. The position of your cup and stem relative to your pelvis and femur, along with the way your leg length and offset will be restored, is decided on your 3D reconstruction, not approximated from a two-dimensional X-ray during surgery. With that groundwork in place, your surgeon is equipped to restore a strong, stable hip and help keep instability from leading to a revision.

Is It Time to Think About Hip Replacement?

Doctors often recommend hip replacement when arthritis has started to limit your day-to-day life and non-surgical treatments, such as changing your activities, medication, physical therapy or injections, have stopped working. Signs you may be a candidate include:

Pain in the hip or groin that makes everyday movement, like walking or climbing stairs, difficult
Hip pain that doesn't let up at rest or that disturbs your sleep
Stiffness that restricts simple movements, such as getting in and out of a car
X-rays or MRIs that show significant arthritis or joint damage

A Look at Your Surgery Day

Your NanoHip™ procedure is performed as outpatient surgery with spinal anesthesia and sedation. You'll be comfortable and unaware of the operation, and you won't need a general anesthetic.

The surgery itself usually lasts between 90 minutes and two hours. Your care team will have you up and taking steps a few hours later, and most patients head home the same day. Your new hip can handle your full weight immediately.

Recovering at Home

Within one to two weeks, most NanoHip™ patients have returned to their daily routines. By six to eight weeks, most are living an active lifestyle again, supported by a home exercise program from their surgeon. Published studies show that most hip replacement patients resume sports, moderate-impact activities among them, about five months after surgery on average.[8]

Back to Sports and Staying Active

With NanoHip™, the aim is an active life without restrictions. Researchers reviewing 37 studies of standard hip replacement found that patients who played sports before surgery generally went back to them, and more than 80% returned to the level they enjoyed before their symptoms appeared.[8] During your consultation, your NanoHip™ surgeon will explain how healing unfolds and lay out a realistic timeline for resuming the activities you enjoy, from a game of pickleball to a stroll around Historic Downtown Carrollton.

Hip Replacement Frequently Asked Questions

How durable is a hip replacement?

Modern hip replacements are built to last, and a well-positioned implant can keep working for decades. Pooled national registry data from the largest study on the topic show about 89% of hip replacements still in place at 15 years, 70% at 20 years and 58% at 25 years.[1] NanoHip™ combines personalized implant positioning with modern implant designs to support a hip that endures without activity restrictions, and your anatomy is mapped in detail before surgery because position plays such a large part in durability.

Why does implant positioning matter for longevity?

How well the cup and stem fit your bone, and how precisely they're placed, are among the biggest factors a surgical team can control. With NanoHip™, biomedical engineers use a CT-based 3D plan to size those components to your bone and to map their placement, your leg length and your offset. Your surgeon approves the plan before your operation. The difference can be measured. In a 200-patient comparison, CT-based 3D planning identified the correct stem size 88% of the time, against 69% with X-ray templating, and the correct cup size 96% of the time, against 56%. Offset errors beyond 3 mm dropped from 23% of patients to 5%, and varus stem placement dropped from 10% to 2%. There were no early fractures or subsidence in the 3D-planned group, compared with three in the X-ray group.[3] NanoHip™ pairs FDA-cleared implants that have long registry track records with our proprietary 3D modeling, optimizing placement while minimizing soft tissue trauma.

Should I consider NanoHip™ for my hip replacement?

If you've been advised to have a hip replacement and you'd like to recover at home, keep up an active lifestyle, and have an implant planned for your particular anatomy, NanoHip™ is worth exploring. It was developed for people who want strong function after surgery, younger and older patients alike. Your NanoHip™ surgeon will determine whether you're a candidate during your consultation and recommend the path that fits your needs.

Are there non-surgical treatments for hip arthritis?

Yes. Depending on your condition, your surgeon may start with activity modification and weight management, physical therapy, anti-inflammatory medication (over-the-counter or prescription), or corticosteroid injections. Your NanoHip™ surgeon will review your imaging and history before recommending a treatment plan. When arthritis has advanced beyond what these options can manage, hip replacement offers consistent, long-lasting results.

Could one leg end up longer after hip surgery?

NanoHip™ plans your leg length and offset, the distance from your hip to your body's midline, on your 3D model before surgery, giving your surgeon a precise target for both. In one 200-patient comparison, CT-based 3D planning cut the rate of offset errors greater than 3 mm from 23% of patients to 5%.[3]

Does NanoHip™ use a muscle-sparing approach?

Yes. NanoHip™ is a minimally invasive hip replacement, and its muscle-sparing approaches reach the hip by working between muscles rather than through them. Randomized trials show these approaches are associated with an easier first few weeks.[7] For long-term performance, though, the precise restoration of your anatomy matters more than how small the incision is. A correctly sized and positioned implant determines how your hip performs for years, and that's all determined in your 3D plan before surgery.[3]

Do I need general anesthesia for hip replacement?

In most cases, no. NanoHip™ surgeons use spinal (regional) anesthesia paired with “twilight” sedation, so you stay comfortable and unaware during surgery without a general anesthetic. A national analysis of more than 380,000 joint replacements found spinal anesthesia was associated with lower 30-day mortality and fewer complications than general anesthesia.[5] General anesthesia is reserved for patients for whom it would be the safer option.

Is NanoHip™ an outpatient procedure?

Yes. Every NanoHip™ procedure is outpatient, and most patients leave the surgery center or hospital about two hours afterward. Research on outpatient hip replacement is extensive: a meta-analysis of 20 studies found no difference in complications between outpatient and inpatient surgery, and outpatients had the added comfort of recovering at home.[6] Your surgeon will confirm that same-day discharge is right for you.

How long will I be in the operating room?

Plan on about 90 minutes to two hours for a NanoHip™ procedure. Since your implant sizes, positions, leg length and offset are set in your 3D plan in advance, fewer decisions have to be made under pressure during surgery. Your surgeon arrives with insights from NanoKnee's proprietary 3D Blueprinting® plan, offered nowhere else.

What does a typical NanoHip™ recovery look like week by week?

Most NanoHip™ patients walk within hours of their surgery and take on light activities in week one. Recovery usually follows this pattern:

7–14 days: managing routine daily activities
2–6 weeks: taking on moderate activity
6–8 weeks: living an active lifestyle without limits

Recovery can vary from one patient to the next.

How will I rebuild strength after surgery?

Most NanoHip™ patients rebuild strength through a home exercise program guided by their surgeon, and formal outpatient physical therapy is arranged only if your surgeon recommends it. Walking begins on the day of surgery, and once your incision heals, usually within two weeks, you'll progress to strengthening, cycling and low-impact activities like swimming. You can track your progress and contact your care team through the NanoKnee app.

Which sports can I play with a hip replacement?

Most NanoHip™ patients go back to activities like walking, cycling, golf, swimming, hiking, tennis, running and skiing without restrictions. Across 37 studies of 6,485 hip replacement patients, more than 80% returned to their pre-symptom level of sport, after an average of about five months, most often in low- and moderate-impact activities.[8]

Will I have good mobility after hip replacement?

Most patients regain the range of motion they need for everyday life and sports, and many recover movement they had gradually lost to arthritis. Your 3D plan positions the cup and stem to restore your hip's center of rotation and offset, which helps keep the hip stable as it moves. Your mobility will keep improving throughout the first year, and our goal is to help every patient regain what arthritis and wear took away.

What kind of incision does NanoHip™ use?

NanoHip™ uses one incision, typically 4 to 6 inches long, closed with absorbable sutures and a cosmetic technique to limit scarring. Your skin will generally heal within two weeks, and you'll continue protecting the area for several weeks beyond that.

What complications should I know about?

All hip replacements carry some risk, including infection, blood clots, dislocation, fracture, leg length differences, nerve injury, implant loosening over time, and anesthesia-related risks. NanoHip™'s standard methods target several of these: spinal anesthesia is associated with fewer perioperative complications than general anesthesia,[5] and pre-operative 3D planning focuses on the component position, leg length and offset problems behind instability and loosening, the two leading reasons for revision.[2][3] Your surgeon will review your specific risks and create a plan to minimize them.

Is hip replacement considered a reliable surgery?

Yes. Hip replacement is regarded as one of the most successful surgeries in medicine. The American Joint Replacement Registry has recorded more than 4.4 million hip and knee replacements since 2012,[9] and in a study of 850 hip replacement patients, only 7% were dissatisfied one year after surgery.[4] Serious complications don't occur often, and some risks can be reduced by choices made before surgery. A national analysis of more than 380,000 joint replacements found lower 30-day mortality and fewer in-hospital complications with spinal anesthesia than with general anesthesia.[5] Board-certified orthopedic surgeons perform NanoHip™ procedures under spinal anesthesia with sedation, and our proprietary 3D modeling supports consistent implant placement and a muscle-sparing approach designed around your anatomy.

Can seniors benefit from NanoHip™?

Absolutely. Hip replacement is routinely performed for older adults with advanced arthritis, and it can bring major improvements in mobility and quality of life. Candidacy depends on your overall health rather than your age, and every NanoHip™ patient is assessed before surgery. Spinal anesthesia, standard with NanoHip™, is associated with fewer perioperative complications than general anesthesia.[5]

Does Medicare cover NanoHip™?

Medicare and most commercial health plans cover hip replacement when it's medically necessary. The pre-operative 3D planning and engineering, however, are not covered by insurance, and depending on your plan, your cost for that portion may be up to $8,500. Our patient navigators will confirm your coverage and out-of-pocket costs before you move forward, and financing is available for non-covered costs.

Is NanoHip™ performed by a robot?

No. Your surgeon performs your hip replacement, and no robot is used in the operating room. AI assists only with planning, helping our biomedical engineers build your 3D model from your CT scan, and your surgeon reviews and approves the final plan. NanoHip™'s precision comes from that pre-operative work, not from operating room technology.
