Key Takeaways
- While hip replacement is one of the most successful surgeries in orthopedics, a small percentage of patients experience complications that affect implant performance over time.
- Warning signs such as persistent pain, swelling, instability, or a feeling that the joint is 'giving way' may indicate implant failure or another post-surgical issue.
- Imaging and lab tests are essential tools for diagnosing the cause of hip replacement complications.
- Many complications can be addressed with revision surgery, which replaces or reconstructs the failed components of the original implant.
- Dr. Collin Haben is a fellowship-trained hip revision specialist serving Cedar Falls, Iowa, and the surrounding Cedar Valley communities.
When a Hip Replacement Isn't Performing Like It Should
Total hip replacement is considered one of the most effective procedures in modern medicine, dramatically improving quality of life for patients with severe arthritis or joint damage.
But 'most patients do well' doesn't mean every patient does. For a portion of those who undergo hip replacement, complications can develop — sometimes years later. Understanding what can go wrong, what warning signs to watch for, and when revision surgery may be necessary can make a significant difference in your recovery and long-term outcome.
Common Complications After Hip Replacement Surgery
1. Implant Loosening
Aseptic loosening — meaning loosening unrelated to infection — is the most common cause of hip replacement failure over time. As the implant ages, the bond between the prosthetic components and the surrounding bone can weaken, leading to pain with weight-bearing and reduced stability.
This is more likely to occur in younger, more active patients who place higher demands on the joint.
2. Dislocation
Hip dislocation after replacement occurs when the ball component of the implant slips out of the socket. It can happen due to improper implant positioning, abnormal movement patterns, or weakened surrounding muscles. Dislocation is most common within the first 3 months after surgery, though it can occur later.
Symptoms include sudden, severe hip pain, an inability to bear weight, and a visibly abnormal leg position.
3. Infection
Infection — called periprosthetic joint infection (PJI) — can occur after any surgery, but it is a particularly serious complication in joint replacement. Bacteria can enter the surgical site during or after the procedure, leading to:
- Persistent warmth, redness, and swelling around the joint
- Drainage from the surgical wound
- Fever and chills
- Increasing pain that doesn't improve with rest
PJI requires aggressive treatment, which often includes antibiotics and surgical intervention. In some cases, a two-stage revision surgery is needed to eradicate the infection before a new implant can be placed.
4. Implant Wear and Fracture
Over time, the materials used in hip implants — including the plastic liner, ceramic components, and metal surfaces — experience wear. In some cases, this can cause microscopic particles to shed into the joint space, causing inflammation and bone loss (a condition known as osteolysis). In rare instances, the implant itself can fracture.
5. Periprosthetic Fracture
A fracture around the hip implant can occur after a fall or trauma. These fractures are complex because the existing hardware complicates both diagnosis and surgical repair.
6. Nerve or Blood Vessel Injury
Damage to nerves or blood vessels near the surgical site can cause numbness, weakness, or circulation problems in the leg. While rare, these complications can affect recovery and functional outcomes.
7. Leg Length Discrepancy
A small difference in leg length after hip replacement is common and often temporary. In some cases, however, a measurable and symptomatic discrepancy persists, causing gait problems and compensatory back or knee pain.
Diagnosing Hip Replacement Complications
If you're experiencing pain, instability, or unusual symptoms after a hip replacement, your orthopedic surgeon will use a combination of diagnostic tools to identify the cause:
- X-rays reveal implant positioning, loosening, fractures, and signs of bone loss.
- CT scans provide more detailed views of complex anatomy or implant problems.
- MRI (with metal artifact reduction protocols) can assess soft tissue and adjacent structures.
- Blood tests (including ESR and CRP) help identify signs of infection or systemic inflammation.
- Joint aspiration — drawing fluid from the joint — is sometimes performed to test for bacteria.
Getting the right diagnosis before pursuing revision surgery is critical. The cause of failure determines the surgical approach.
When Is Revision Hip Surgery Necessary?
Not every complication requires surgery. Some issues — like mild inflammation or a minor leg length discrepancy — can be managed conservatively. However, revision surgery is typically recommended when:
- The implant is significantly loose or fractured
- Recurrent dislocations cannot be managed with bracing or activity modification
- Infection persists despite antibiotic treatment
- Bone loss (osteolysis) is progressing and threatening implant stability
- Pain is severe, persistent, and limiting daily function
Revision hip surgery is more complex than primary replacement. It may involve removing one or all implant components, addressing bone defects, reconstructing damaged tissue, and placing new, often custom or larger, prosthetic components. The goal is to eliminate pain, restore stability, and extend the functional life of the joint.
What to Expect from Revision Surgery
Revision surgery typically requires:
- Longer operating time than a primary replacement
- Specialized implants designed for revision scenarios — Dr. Haben uses high-performance implants from Enovis™ that are specifically engineered to address the complex demands of revision patients.
- Extended recovery and rehabilitation
- Follow-up imaging to monitor the new implant
Finding a surgeon with fellowship training and experience in complex revision cases is essential. Not all orthopedic surgeons perform revision procedures, and outcomes are closely tied to surgical expertise.
Preventing Complications After Hip Replacement
While not all complications can be prevented, patients can reduce their risk by:
- Following all post-surgical activity restrictions precisely
- Attending all physical therapy sessions
- Avoiding high-impact activities early in recovery
- Reporting any new or worsening pain promptly — don't wait
- Keeping all follow-up appointments so the implant can be monitored over time
Maintaining a healthy weight also reduces mechanical stress on the implant, which can extend its lifespan.
Expert Hip Revision Care in Cedar Falls, Iowa
If your hip replacement isn't working the way it should, a second opinion from a fellowship-trained revision specialist can open new doors. Dr. Collin Haben offers expert evaluation and complex case management for patients whose original hip replacement has failed or is causing ongoing problems. As a skilled hip replacement and revision surgeon, Dr. Haben uses advanced technology and a thorough, individualized approach to create treatment plans that make sense for each patient's unique situation.
Frequently Asked Questions
What are the most common signs that a hip replacement has failed?
Warning signs of hip replacement failure include persistent or worsening pain that didn't exist before surgery, swelling, instability or a sense that the joint is giving way, difficulty bearing weight, fever, or drainage at the surgical site. If you notice any of these symptoms, contact an orthopedic specialist for evaluation.
How long do hip replacements typically last?
Most hip implants last 15 to 20 years or longer with appropriate care. However, younger patients or those with high activity levels may require a revision procedure sooner. Advances in implant materials — such as Vitamin E-blended polyethylene used in Enovis™ components — have significantly extended implant longevity.
How is hip replacement failure diagnosed near me?
Diagnosis involves a combination of physical examination, X-rays, and potentially CT imaging, blood tests, or joint fluid analysis. An experienced orthopedic surgeon will evaluate both your symptoms and your imaging to identify the specific cause of failure before recommending a treatment plan.
Is revision hip surgery more risky than the original replacement?
Revision procedures are generally more complex and carry slightly higher risks than primary replacements due to factors like scar tissue, bone loss, and the need to work around existing hardware. However, in experienced hands, revision surgery is a well-established procedure with strong outcomes. Surgeon experience is a key factor in minimizing risk.
