On the basis of the distribution-based approach, the MCID was 8.7 using a method in which the standard deviation of the baseline score was divided by 2. The study included 343 hips with an average follow-up period of 48 months. Multivariate logistic regression was performed to determine predictors of achieving the MCID and PASS. Distribution- and anchor-based methods with receiver operating characteristic analysis were used to determine the thresholds. The MCID, PASS, and SCB thresholds were calculated for the NAHS at minimum 1-, 2-, and 5-year follow-up. Patients were excluded if they underwent previous ipsilateral hip surgery, underwent gluteus medius repair, or had a previous hip condition. Patients who underwent hip arthroscopy for femoroacetabular impingement and completed postoperative questionnaires between August 2019 and March 2020 were included. The secondary aim was to identify variables associated with achievement of the thresholds. The purpose of this study was to improve the interpretability of the Nonarthritic Hip Score (NAHS) by determining the minimal clinically important difference (MCID), patient acceptable symptomatic state (PASS), and substantial clinical benefit (SCB) after hip arthroscopy for femoroacetabular impingement. We express our sincere gratitude to Marina Capilla for her support by editing this manuscript and creating the artistic painting (Fig 2). We observed that the bigger the tear and retraction, the Acknowledgment The faster the repair, the better the results without being influenced by the type of repair. Patte II cases showed the best results after repair, demonstrated by US. This reversibility can be quantified by using US imaging (histogram reduction, histogram ratio reduction, echogenicity reduction, pennate pattern, and pennate angle augmentation). Our study suggests that supraspinatus atrophic muscle changes after repair can be reversed. 6, 8 At the same time, it is clearly understood by many authors that recovery after a cuff tendon repair is associated not only with good tendon Conclusions Our US revision shows an objective evaluation of muscle recovery from atrophy after surgery, with a significant augment of anatomic structural changes in the muscle belly of the repaired tendons in terms of pennate pattern visualization, pennate angle increment, and H and HR reduction.Ĭhronic rotator cuff tears are associated to muscle atrophy and FI. The predominant activity in women was housework (light to medium), but in men, it was equally distributed Discussion The dominant side was affected in 76 cases (69.1%) and the nondominant side in 34 cases (30.9%). Twenty-two patients were lost from the study due to different causes, leaving a total of 110 cases that underwent a prospective follow-up of at least 12 months.ĭescriptive results are shown in Table 1. The mean age at surgery was 61 ± 8 years (range, 46-77). The following data were collected: age, Results We excluded patients with previous shoulder surgery or fractures, cases of supraspinatus tendon nonrupture, patients who did not undergo supraspinatus tendon repair, subscapular or infraspinatus tendon tears, and patients with Goutallier grade 4 atrophy. Adult patients with full-thickness supraspinatus tendon tears, arthroscopically confirmed, were included in the study. Recurrence of symptoms was 13%, related to worse results of PA and echogenicity compared to nonrecurrences.Ī prospective observational nonrandomized study was conducted between 20. Minimal clinically important differences for Constant and visual analog scale were 44.45 ± 12.87 and 6.54 ± 1.41, respectively. We observed improvement after surgery in Constant score from 35 to 85 ( P <. Although Patte III cases almost did not improve in terms of atrophy, they improved clinically. Patte II cases showed the most significant improvement in terms of imaging evaluation of atrophy. Mean PA on the contralateral side was 8.6 preoperatively. Supraspinatus echogenicity compared to trapezius muscle reduced from 0.43 to 0.36 ( P <. 365) and slightly deteriorated on the contralateral side from 51.6 to 52.9 ( P =. Echogenicity improved from 54.5 to 51.0 ( P =. We detected a correlation between atrophy and age in terms of echogenicity and PA ( P =. In total, 110 supraspinatus tears underwent arthroscopic repair (2015-2018).
