Evaluation of Forgotten Joint Score in total hip arthroplasty with Oxford Hip Score as reference standard.

ABSTRACT: Background and purpose - Total hip arthroplasty (THA) is performed mainly because of pain. To evaluate the result after surgery, different questionnaires measuring the patient-reported outcome regarding quality of life are used. Forgotten Joint Score (FJS), designed to chart postoperative symptoms, was developed to find subtle differences between patients who report that their operated hip is "very good" or "excellent." We evaluated whether FJS provides additional information compared with the Oxford Hip Score (OHS) and ceiling and floor effects with use of these instruments. We also studied level of internal consistency for OHS and FJS, and the reproducibility of the FJS. Patients and methods - 111 patients who underwent unilateral primary THA in 2015 were included. The participants answered 2 questionnaires: Forgotten Joint Score and Oxford Hip Score. Floor and ceiling effects were recorded for each of the instruments and agreement between them. The FJS was studied with respect to reproducibility and level of internal consistency. Results - OHS ceiling effect (31%) was higher compared with FJS (21%), whereas the OHS seemed to provide a more nuanced picture of patients with an inferior clinical result. Floor effect for FJS was 3% and 0% for OHS. The degree of explanation was 68% between the 2 questionnaires (linear regression, r2 = 0.68). FJS items had a high internal consistency (Cronbach's a = 0.93) and reproducibility (Pearson correlation = 0.87, ICC = 0.93); 92 patients answered on 2 distributions of the FJS questionnaires, 19 patients had identical answers. Interpretation - OHS had a larger ceiling effect than FJS, which could indicate that FJS is a more fine-tuned instrument to separate patients with good to excellent outcome after THA. The high internal consistency of FJS indicates that the items of the instrument consistently cover the construct of joint awareness.

Project description:PurposeTo contextualize the Forgotten Joint Score (FJS-12) by identifying a patient acceptable symptomatic state (PASS) threshold for patients undergoing hip arthroscopy and to investigate factors which correlated with postoperative FJS-12 score.MethodsAll patients who underwent hip arthroscopy for femoroacetabular impingement (FAI) under the care of a single surgeon between January 2018 and November 2019 were prospectively identified and included. Exclusion criteria were Tönnis classification grade 2 or greater. Data (including FJS-12, EuroQol-5 Dimension-5L [EQ-5D-5L], visual analog scale (VAS), and 12-item International Hip Outcome Tool (iHOT-12) scores) were available before surgery and at a minimum of 1 year after surgery. PASS was calculated using an anchor-based approach and receiver operator characteristic curve analysis. Pearson correlation analysis was used to correlate preoperative and postoperative factors with postoperative FJS-12 score.ResultsSeventy-seven patients (54 female, 23 male; mean age 30.3 years [standard deviation {SD} 8.2]) were included. Linked longitudinal follow-up data were available for 65 patients (84%) at a mean of 23.8 months (SD 6.4). Six patients required reoperation. Mean postoperative FJS-12 score was 46.5 (SD 33.1) and mean change in score was 27.2 (SD 30.6, P < .001). The PASS threshold for the FJS-12 was 38.5 (sensitivity 80%, specificity 88%), and the area under the curve was 0.852 (95% confidence interval 0.752-0.951). Overall, 53.8% of patients achieved this score. Postoperative FJS-12 score has moderate correlations with preoperative EQ-5D-5L, iHOT-12, and FJS-12 scores, and strong correlations with EQ-5D-5L, iHOT-12 and VAS scores after surgery.ConclusionsWe report a postoperative PASS threshold of 38.5 points for the FJS-12 after hip arthroscopy for FAI in a United Kingdom population. This value can act as a quantifiable target for clinicians using the FJS-12 to monitor patient outcomes in practice. FJS-12 has strong correlations with EQ-5D-5L, iHOT-12, and VAS at a minimum 12 months after surgery.Clinical relevanceWe have calculated the patient acceptable symptomatic state of the Forgotten Joint Score to be 38.5 points at short-term follow-up. This can assist clinicians in determining whether surgical interventions related to hip arthroscopy for FAI are meaningful to the patient.
