Abstract
PURPOSE: The Forgotten Joint Score (FJS-12) is a scoring system initially created to assess post arthroplasty outcomes. It has since been used to evaluate Anterior Cruciate Ligament surgery outcomes. Our study aims to evaluate the applicability and validity of the FJS-12 in post Anterior Cruciate Ligament reconstructed patients, and to assess correlation with established Patient Reported Outcome Measure Scores in the same population. DESIGN: Case series, level 3 evidence. METHODS: We conducted a cross sectional study across patients who had undergone Anterior Cruciate Ligament reconstruction and carried out the FJS-12 questionnaire by phone interview. Patients who had undergone primary Anterior Cruciate Ligament reconstruction were considered for the study. RESULTS: The average Forgotten Joint Score-12 for all 82 patients was 71.4 (±22.9), which corresponded to a normal distribution. The average Lysholm and Tegner score at the 2-year post-operative visit was 93.5 ± 9.5 and 5.8 ± 1.8 respectively and the distribution was non-normal. We noticed a large ceiling effect of 42.7% in the Lysholm scores, but only 8.4% in FJS-12. There was a weak correlation with Lysholm and a positive correlation with Tegner. CONCLUSIONS: Forgotten Joint Score-12 seems to be a promising patient reported outcome measure that can be used in evaluating post Anterior Cruciate Ligament reconstruction outcomes. It is more discerning than traditional scores and is easy to administer thus it can used in the clinical follow-up of patients. With the scores being normally distributed, it makes for a meaningful PROMS and would allow more accurate application of parametric statistical tests.
