What is Joint Awareness after Patellofemoral Arthroplasty Evaluated with the Forgotten Joint Score: A Comparison Study about?

## Objective The aim of the present study was to compare the forgotten joint score (FJS) in patients with isolated patellofemoral osteoarthritis who underwent patellofemoral arthroplasty (PFA) __versus__ those who underwent total knee arthroplasty (TKA) and to analyze the predictors of the FJS after PFA. ## Methods From January 2014 to December 2017, a retrospective cohort study of 56 consecutive patients with isolated patellofemoral osteoarthritis underwent PFA and were included in the PFA group. The patients in the PFA group were matched in a 1:1 ratio based on age, sex, body mass index (BMI), and follow‐up duration; 56 patients with isolated patellofemoral osteoarthritis underwent cruciate‐retaining TKA (TKA group). The FJS, range of motion of the knee, and Knee Society Score were assessed at 1 and 3 years postoperatively. In addition, the associations between the potential influencing factors (age, sex, BMI, and preoperative Iwano score of the patellofemoral joint) and the FJS were analyzed using multiple linear regression in the PFA group. ## Results There were no significant differences between the PFA and TKA groups regarding age (__P__ = 0.316), sex (__P__ = 0.832), BMI (__
