Key Takeaway
Consider one-stage revision for chronic PJI given comparable infection control and reduced treatment burden compared to two-stage revision.

This retrospective cohort study examined patients with chronic periprosthetic joint infection who underwent surgical treatment at an orthopedic center. The analysis compared a one-stage revision group (n=16) against a two-stage revision group (n=27). The primary outcome assessed infection control rates at 24 months postoperatively, with secondary outcomes including Harris hip score, Knee Society Score, and incidence of postoperative complications within 90 days. The mean follow-up duration was 29.5 ± 4.5 months.

Results indicated that infection control rates at 24 months were comparable between the two approaches, with one-stage revision achieving 87.5% (14/16) and two-stage revision achieving 88.9% (24/27); the difference was not statistically significant (P = 0.89). Regarding functional outcomes, the one-stage group demonstrated significantly greater improvement in Harris hip score (52.8 ± 6.3 to 85.2 ± 5.1) compared to the two-stage group (55.1 ± 5.9 to 80.4 ± 6.7) (P = 0.021). Similarly, Knee Society Score improvement was significantly greater in the one-stage group (54.3 ± 6.5 to 84.7 ± 5.8) versus the two-stage group (56.4 ± 7.0 to 81.2 ± 6.9) (P = 0.032).

Postoperative complication rates within 90 days showed no significant difference between groups, with one-stage revision reporting 18.75% (3/16) and two-stage revision reporting 14.81% (4/27) (P > 0.05). No serious adverse events were reported. The study noted limitations associated with the prolonged treatment cycle and heavy medical burden inherent to two-stage revision. Funding sources and conflicts of interest were not reported. The authors suggest that one-stage revision may effectively avoid a second surgery, shorten the treatment cycle, and reduce patient suffering and economic burden.

Imagine waking up from surgery, only to face a second operation months later. That is the reality for many people with chronic joint infections. They endure long hospital stays, heavy antibiotics, and a slow road to recovery.

But new research suggests a different path might be possible.

Periprosthetic joint infection (PJI) is a serious problem. It happens when bacteria grow around a hip or knee replacement. Once this starts, the infection can linger for years.

Doctors usually treat this with a two-stage process. First, they remove the infected implant and place a temporary spacer. Then, they wait weeks or months to kill the bacteria with antibiotics. Finally, they put in a new implant.

This process takes a huge toll. Patients lose mobility for a long time. The cost is high. And the emotional stress of waiting is heavy.

Many patients feel stuck in this cycle. They want to get back to walking, gardening, and living their lives. But the current standard of care often keeps them in a waiting room for months.

The surprising shift

For decades, doctors believed one surgery was not enough. They thought removing the implant once and putting it back immediately was too risky. The fear was that the infection would return.

But here is the twist. A new study challenges this old belief. It shows that for the right patients, doing it all in one go works just as well.

What scientists didn't expect

Think of your immune system like a security team. In the old two-stage method, you remove the guard (the implant) and leave the building empty for a long time. The bad guys (bacteria) have time to hide in the walls.

In the one-stage method, you swap the guard immediately. The security team is never off duty. This keeps the infection under control while you heal faster.

The study looked at patients who had clear evidence of which bacteria was causing the problem. When doctors knew exactly what they were fighting, they could choose the right medicine right away.

The study snapshot

Researchers looked at records from an orthopedic center between July 2018 and November 2023. They compared two groups of patients.

One group had the one-stage surgery. The other group had the traditional two-stage surgery. The team tracked these patients for about two and a half years. They checked if the infection stayed gone and how well the joint moved.

The results were promising. Infection control was nearly identical in both groups. About 88% of patients in the two-stage group stayed infection-free. About 88% of patients in the one-stage group stayed infection-free.

The real winner was recovery speed. Patients in the one-stage group regained better hip and knee function. They moved more freely and felt better sooner.

This doesn't mean this treatment is available yet.

Complication rates were similar for both groups. This means the one-stage surgery is safe when done correctly. It avoids the need for a second operation. This saves money and reduces patient suffering.

The bigger picture

Experts say this fits into a larger trend. Medicine is moving toward faster, less invasive treatments when safe. This study supports that shift.

However, this only works for specific cases. If the infection is too severe or the bacteria are unknown, the two-stage method remains the safer choice. Doctors must carefully evaluate each patient before deciding.

If you or a loved one has a joint infection, talk to your doctor about your options. Ask if you are a candidate for one-stage revision.

Key questions to ask include:

  • Do we know exactly which bacteria is causing the infection?
  • Is my immune system strong enough for one surgery?
  • What are the risks of waiting versus acting now?

Do not stop your current treatment without medical advice. This research offers hope, but it requires careful planning.

This study has some limits. It looked at a specific group of patients at one center. The numbers were relatively small. Also, the results apply only to chronic infections where the bacteria are known.

We cannot say this works for every single person. Every body is different.

More research is needed to confirm these findings across different hospitals. Future trials will likely test this method on more patients.

If approved, this could change how doctors treat joint infections. It could mean shorter hospital stays and happier patients. Until then, the two-stage method remains the standard for many. But the door is opening for a faster, better way to heal.

ObjectiveThis study aims to compare the short-term clinical outcomes of one-stage and two-stage revision surgeries for treating chronic periprosthetic joint infection (PJI), addressing the limitations of the prolonged treatment cycle and heavy medical burden associated with two-stage revision, and evaluating the feasibility and effectiveness of one-stage revision as an alternative therapeutic strategy.MethodsThis retrospective cohort study included PJI patients who underwent surgical treatment at our orthopedic center from July 2018 to November 2023. Patients were divided into one-stage revision group (n=16) and two-stage revision group (n=27) based on the surgical approach. The primary outcome was the infection control rate at 24 months postoperatively, while secondary outcomes included Harris hip score(HHS), Knee Society Score (KSS), and the incidence of postoperative complications within 90 days.ResultsThere were no significant differences between the two groups in baseline characteristics. The mean follow-up duration was 29.5 ± 4.5 months. The infection control rate was comparable between one-stage (87.5%, 14/16) and two-stage (88.9%, 24/27) revision (P = 0.89). For hip function, HHS improved from 52.8 ± 6.3 to 85.2 ± 5.1 in the one-stage group and from 55.1 ± 5.9 to 80.4 ± 6.7 in the two-stage group. For knee function, KSS improved from 54.3 ± 6.5 to 84.7 ± 5.8 in the one-stage group and from 56.4 ± 7.0 to 81.2 ± 6.9 in the two-stage group. The one-stage group demonstrated significantly greater functional improvement in both HHS (P = 0.021) and KSS (P = 0.032). Postoperative complication rates were 18.75% (3/16) and 14.81% (4/27), respectively (P>0.05).ConclusionIn PJI patients with clear preoperative pathogen identification, one-stage revision surgery demonstrates comparable infection control rates and safety to two-stage revision after two years of follow-up, with superior joint function recovery. One-stage revision can effectively avoid a second surgery, shorten the treatment cycle, and reduce patient suffering and economic burden, making it an effective treatment option for eligible PJI patients.
