Patient satisfaction reporting for patellofemoral arthroplasty is significantly lacking: a systematic review.

: Patellofemoral Arthroplasty (PFA) has been shown to be successful in restoring knee function and quality of life in patients with the isolated patellofemoral disease. Patient satisfaction has been suggested as an indicator of the quality of elective orthopedic operations, although there remains no standardized method to collect and evaluate satisfaction. The present study offers a systematic review of the available literature concerning patient satisfaction following PFA to assess common methodologies for reporting patient satisfaction. : A query of the Medline database produced 116 articles that were reviewed for inclusion in the review. The following inclusion criteria were used to identify suitable articles: English language, clinical outcomes study related to PFA, and patient-reported satisfaction as an outcome measure. : Seven studies met inclusion criteria and were eligible for review. The highest level of evidence was level-III. The study publication dates ranged from 2009 to 2016, with six published in 2015 & 2016. In total, 320 PFAs were performed on 267 patients. Four articles reported the proportion of included patients who had previous knee surgeries (range: 20-60%). Three studies used ordinal scales to rate patient satisfaction. Four studies (57.1%) reported the numeric proportion of patients satisfied following PFA, which ranged from 76% to 96.5%. Two studies used Visual Analog Scale methods. For these two studies, one of them reported the mean satisfaction score as 7.5/10, and the other reported a median of 90/100. : The available literature on patient satisfaction after PFA was found to be limited, with low-quality evidence and variable methodology.
