MCID and PASS in Knee Surgeries. Theoretical Aspects and Clinical Relevance References

Abstract

The application and interpretation of patient-reported outcome measures (PROM), following knee injuries, pathologies, and interventions, can be challenging. In recent years, the literature has been enriched with metrics to facilitate our understanding and interpretation of these outcome measures. Two commonly utilized tools include the minimal clinically important diference (MCID) and the patient acceptable symptoms state (PASS). These measures have demonstrated clinical value, however, they have often been under-or mis-reported. It is paramount to use them to understand the clinical signiicance of any statistically signiicant results. Still, it remains important to know their caveats and limitations. In this focused report on MCID and PASS, their deinitions, methods of calculations, clinical relevance, interpretations, and limitations are reviewed and presented in a simple approach.

Previous cartilage surgery is associated with inferior patient‐reported outcomes after knee arthroplasty

“…This represents the first study of patient-reported results in knee arthroplasty patients with previous cartilage lesions where PASS is reported. Reporting the percentage of patients having reached the PASS threshold offers several advantages, as outlined in a recent review by Mabrouk et al [26]. It ensures that identified differences are not only statistically significant but also clinically relevant.…”

The Delaware‐Oslo ACL Cohort treatment algorithm yields superior outcomes to usual care 9–12 years after anterior cruciate ligament reconstruction

“…Whether treatment after ACLR is successful [9] depends on patients' satisfaction with their outcomes [10,11]. Patient satisfaction with current knee status often seems more clinically valuable than the reported outcome scores [10].…”

“…The patient-acceptable symptoms state (PASS) is a simple and clinically relevant measure that refers to a condition that a patient would deem satisfactory [12]. Clinicians, researchers and policymakers can use valid PASS thresholds for a given patientreported outcome measure to better understand the clinical meaningfulness of the scores and to identify what constitutes a satisfactory outcome [10,11].…”

Checklists, risk of bias tools, and reporting guidelines for research in orthopedics, sports medicine, and rehabilitation

“…A better understanding of how to perform an efective literature search, of the core outcomes to report, the meanings of p values and minimal clinically important diferences or patient acceptable symptoms state are mandatory for the research process [2,26]. New technologies like Artiicial intelligence bot ChatGPT might lead to further demands in methodological robustness and awareness of reporting standards [16].…”
