Abstract Background: Patient’s satisfaction after surgery was traditionally assessed by pre, and post-surgical scores and Patient-Reported Outcome Measures (PROMs) scales. Patients treated by Total hip arthroplasty (THA) usually perform well; therefore, it is useful to have a PROMs’ scale with a low ceiling effect as the Forgotten Joint Score-12 (FJS-12). PROMs have to be validated in the local language to be used. This study aims to perform a psychometric validation of the Italian version of FJS-12 in a group of consecutive patients treated by THA.Methods: Each patient completed both the Italian version of FJS-12 and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) in preoperative evaluation, after two weeks and 1 month, 3 months and 6 months postoperative follow-up. The reliability, internal consistency, test-retest reliability, and measurement error were evaluated.Results: 53 patients were included. Cronbach’s α between 0.6 and 0.9 indicated good internal consistency for the FJS-12. The test-retest reliability was acceptable. The Pearson correlation coefficient between the FJS-12 and WOMAC was 0.238 (P=0.087) at baseline, r = 0.637 (P < 0.001) at 1 month, r = 0.490 (P < 0.001) at 3 months and r = 0.572 (P < 0.001) at 6 months. The ceiling effect was above the acceptable range (15%) for FJS-12 in 1 month (26.4%) and WOMAC in 6 months follow-up (24.5%).Conclusions: An excellent test-retest reliability, a good internal consistency, and a good validity by medium-high correlation with the WOMAC were assessed for FJS-12. However, the responsiveness for the FJS-12 score was not assessed.

Purpose: Performance-based outcome measures are becoming increasingly important in health care. The 2-minute walk test (2MWT) and the Timed Up and Go test (TUG) are frequently used in clinical trials as performance-based tests in many diseases including osteoarthritis. The purposes of this study were: (1) to determine test-retest reliability of data for the 2MWT and the TUG; (2) to determine minimal detectable change (MDC) scores for the TUG and 2MWT in patients with total hip arthroplasty (THA). Methods: 37 patients, who had undergone primary THA, were included. Patients twice performed trials for the 2MWT and TUG on the same day. In addition to demographic data of patients, the Harris Hip Score, 2MWT and TUG scores were recorded. Results: The TUG and 2MWT showed excellent test-retest reliability. The Intraclass correlation coefficient ICC (2,1), Standard error of measurement (SEM) and minimal detectable chance at the 95% CI (MDC95) for TUG were 0.96, 0.59 seconds and 1.62 seconds respectively. The ICC (2,1), SEM and MDC95 for 2MWT were 0.96, 6.37 m and 17.56 m respectively. Conclusion: Clinicians and researchers can be confident that greater changes than 1.62 seconds for TUG and 17.56 m for the 2MWT over time represent a real clinical change in rehabilitation process in patients with THA. Both the 2MWT and TUG may assist in early identification of patients who may need additional rehabilitation to reduce the potential for poor outcomes after THA. Therefore, both of these tests can be used in a clinical setting with a small measurement error.

Test Retest Reliability

Abstract Background The L test is a modified version of the timed up and go test (TUG) with an L-shaped walking path. The L test is more extensive than other performance tests, especially in turn direction and specific tasks. The study aimed to evaluate the test-retest reliability, concurrent validity, and minimal detectable change of the L test in patients with total hip arthroplasty (THA). A cross-sectional study was conducted with 33 unilateral and primary THA patients. The L test was performed twice with an interval of an hour on the same day for the test-retest reliability. Timed up and go test (TUG), five times sit to stand test (FTST), and Harris hip score (HHS) were carried out for the analysis of the concurrent validity of the L test. Results The mean age of the participants was 74.6 ± 10.3 years. The ICC score of the L test was 0.992. Test-retest reliability was excellent. SEM95 and MDC95 values were 3.39 and 9.39, respectively. Both TUG and HHS were strongly correlated with the L test (r1 = 0.889, r2 = −0.568, p < 0.001). However, there was no significant correlation between FTST and L test (r = 0.024, p > 0.05). Conclusions The L test is valid and reliable performance measurement in patients with primary unilateral THA. MDC95 of the L test is an essential reference for clinicians in the rehabilitation follow-up process of THA patients.

Abstract Introduction Evolving surgical techniques in total hip arthroplasty (THA) have sought to make the surgical procedures safer. This requires having highly reproducible incision landmarks and simplifying the procedures. The postero-posterolateral approach, a very posterior incision in the hip, meets those requirements. However, this has not helped to reduce the post-operative dislocation rate. The aim of this study was to assess the relevance of combining the postero-posterolateral approach and next-generation dual mobility cups (DMC) in terms of dislocation risk. Materials and methods One hundred and fifty-eight THA were performed consecutively using the postero-posterolateral approach on 150 patients, by a single surgeon, over a 49-month period (November 2010 to December 2014). All acetabular implants were impacted. Results Average length of the incision was 7 cm (6 to 9 cm). Mean duration of the surgical procedure was 75 minutes (40 to 100). Mean blood loss was estimated at 210 cc (25 to 410 cc). All patients could walk with assistance the day before transferring to a rehabilitation centre. There was one posterior dislocation (0.63%), without recurrence. Conclusion The straightforwardness and reproducibility of the anatomical landmarks used for the postero-posterolateral approach, added to the stability of the dual mobility cup, result in a safe combination in the therapeutic THA arsenal.

Utility Scores

Objectives: Do utility scores based on patient preferences and scores based on community preferences agree? The purpose is to assess agreement between directly measured standard gamble (SG) utility scores and utility scores from the Health Utilities Index Mark 2 (HUI2) and Mark 3 (HUI3) systems.Methods: Patients were assessed repeatedly throughout the process of waiting to see a surgeon, waiting for surgery, and recovery after total hip arthroplasty (THA). Group mean scores are compared using paired t-tests. Agreement is assessed using the intraclass correlation coefficient (ICC).Results: The mean SG, HUI2, and HUI3 (SD) scores at assessment 1 are 0.62 (0.31), 0.62 (0.19), and 0.52 (0.21); n=103. At assessment 2, the means are 0.67 (0.30), 0.68 (0.30), and 0.58 (0.22); n=84. There are no statistically significant differences between group mean SG and HUI2 scores. Mean SG and HUI3 scores are significantly different. ICCs are low.Conclusions: At the mean level for the group, SG and HUI2 scores match closely. At the individual level, agreement is poor. HUI2 scores were greater than HUI3 scores. HUI2 and HUI3 are appropriate for group level analyses relying on community preferences but are not a good substitute for directly measured utility scores at the individual leve.
