Background

As total knee replacement (TKA) procedures shift more frequently to outpatient or short-stay models, patients are assuming greater responsibility for their recovery process. Navigating pain, rehabilitation milestones, and emotional responses without sustained hospital support can be overwhelming. This study, conducted at Kaohsiung Medical University in Taiwan, aimed to assess whether a patient-specific Integrated Education Program (IEP) could better support this transition.

The IEP was designed to proactively guide patients through the preoperative and postoperative phases. It incorporated one-on-one education sessions, a structured prehabilitation program, group-based inpatient education, and structured follow-up via phone calls. The study sought to determine whether this comprehensive and personalized approach could improve outcomes related to pain, anxiety, and functional recovery in the early postoperative phase compared to standard care alone.

What question is the study trying to answer?

Can a personalized and structured education program significantly improve short-term outcomes in patients undergoing TKA? Specifically, the researchers investigated whether the IEP could reduce perioperative pain and anxiety and enhance early functional recovery compared to a standard, less interactive care model. The study focused on metrics that matter to both patients and providers: pain intensity, emotional readiness, and functional mobility.re?

What are the experimental groups and differences in the trial?

The study used a controlled trial design involving two separate hospitals with similar surgical protocols but different educational approaches:

  • Hospital A (Intervention Group): Patients received the IEP, which included:

    • A one-on-one education session with a trained nurse prior to surgery.

    • A prehabilitation program designed by physical therapists.

    • In-hospital group education covering post-op expectations and mobility strategies.

    • Regular follow-up phone calls over a three-month period to reinforce guidance and address concerns.

  • Hospital B (Control Group): Patients received standard care:

    • A generic printed education manual prior to surgery.

    • Routine physical therapy during their 5-day hospital stay.

    • Follow-up visits only when scheduled, with no structured outreach or reinforcement.

Importantly, both groups received the same surgical techniques and rehabilitation protocols. The main difference was the structure, frequency, and personalization of the education and support provided.

What did the study find?

The results strongly favored the Integrated Education Program. Here are the major findings:

Pain: Patients in the IEP group reported significantly lower pain scores at all time points—beginning on hospital admission, continuing through discharge, and extending into the 6-week follow-up. This suggests that understanding what to expect and being actively guided through recovery reduced perceived pain.

Anxiety: The intervention group also showed significant reductions in both state and trait anxiety (using the State-Trait Anxiety Inventory). Unlike the control group—whose anxiety levels remained elevated until after discharge—the IEP group experienced notable emotional relief earlier in the hospitalization process. The proactive education helped prepare them mentally and emotionally for what was to come.

Function: Function was assessed using both objective (American Knee Society Score - AKS) and subjective (WOMAC) tools. Despite starting with lower baseline functional scores, the IEP group demonstrated faster and more complete recovery. By the 6-week mark, they outperformed the control group in walking ability, knee flexion, and overall self-reported functional independence.

In summary, the IEP group experienced less pain, less anxiety, and better function, even though they began in a more compromised state. These findings reinforce the impact of education as a therapeutic intervention, not just an administrative formality.

Potential limitations to the study

Non-randomized hospital comparison: The use of two separate hospitals introduces potential confounding variables related to staffing, environment, or patient population.

  • Baseline differences: The intervention group started with slightly worse WOMAC scores, making the functional improvements impressive but potentially harder to generalize.

  • Bundled intervention: Because the IEP included multiple components—prehab, group education, follow-ups—it's not possible to determine which element contributed most to the improved outcomes. This limits insight into how a leaner version of the program might perform.

Despite these limitations, the study was well-designed, transparent about its methods, and used validated measurement tools.

What does this mean for you as a patient?

For patients preparing for total knee replacement, this study highlights a crucial truth: the more you understand and engage in your recovery process, the better your outcome is likely to be. Structured education that is interactive, personalized, and reinforced over time is far more effective than reading a pamphlet or attending a single class.

If you're planning TKA, ask your care team what educational support is available. Do you have access to prehabilitation sessions? Are there follow-up calls or email check-ins post-discharge? Does your surgeon's office offer a formal program, or is PT education handled independently? The answers to these questions could affect your recovery trajectory.

You can also advocate for yourself by requesting more detailed guidance and asking specific questions about pain management, mobility expectations, and timelines. The more informed you are, the more confident you’ll be—and that confidence translates into lower anxiety and better results.

Final thoughts

This study strengthens the case for patient-centered, education-driven care models in orthopedic rehabilitation. As total joint replacement becomes more efficient and outpatient-based, the risk is that patients may feel underprepared. Structured education programs—especially those with personalized guidance, early engagement, and follow-up—are emerging as powerful tools to bridge that gap.

Education isn’t just preparation—it’s medicine. The results here are a clear call to action for clinics, providers, and systems to prioritize it accordingly.
