Polish Validation and Language Adaptation of the Banff Patellofemoral Instability Instrument 2.0.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The importance of patient-reported outcome measures (PROMs) is becoming increasingly recognized in the orthopaedic field. The Banff Patellofemoral Instability Instrument 2.0 (BPII 2.0) is a disease-specific tool designed for patients with patellofemoral instability. Purpose: To adapt, translate, and validate the BPII 2.0 into Polish, to enable its use by Polish-speaking professionals for the evaluation of patients who present with patellofemoral instability. Study Design: Cohort study (Diagnosis); Level of evidence, 3. Methods: The final Polish version of the BPII 2.0 was investigated in patients with a confirmed diagnosis of recurrent patellofemoral joint (PFJ) instability. Patients completed 2 sets of PROMs, the BPII 2.0, Anterior Knee Pain Scale (Kujala), Norwich Patellar Instability (NPI) score, Lysholm knee score, and International Knee Documentation Committee [IKDC] Subjective Knee Form, at the clinic visit and 7 to 14 days later. The following psychometric properties were assessed: face validity, floor and ceiling effects, test-retest reliability, internal consistency, construct validity, standard error of measurement (SEM), and minimal clinically important difference (MCID). The reliability was evaluated by measuring the internal consistency (Cronbach alpha) and test-retest reliability (intraclass correlation coefficient). Pearson correlation coefficients were used to examine the validity. Results: The study population consisted of 80 postoperative patients (29 males, 51 females) aged 12 to 37 years with a confirmed diagnosis of recurrent PFJ instability. Face validity was assessed with an expert clinician group and an expert-patient group. No floor or ceiling effects were observed. The test-retest reliability of the BPII was 0.995 ( Conclusion: This study demonstrated that the Polish version of the BPII 2.0 is a reliable and valid instrument for Polish-speaking patients with recurrent patellofemoral instability. It will enable multicenter, international studies through uniform application of the functional assessment of patients with PFJ instability.
