IMPORTANCE The Enhanced Recovery After Surgery (ERAS) care protocol has been shown to improve outcomes compared with traditional care in certain types of surgery.OBJECTIVE To assess the association of use of the ERAS protocols with complications in patients undergoing elective total hip arthroplasty (THA) and total knee arthroplasty (TKA). DESIGN, SETTING, AND PARTICIPANTS This multicenter, prospective cohort study included patients recruited from 131 centers in Spain from October 22 through December 22, 2018. All consecutive adults scheduled for elective THA or TKA were eligible for inclusion. Patients were stratified between those treated in a self-designated ERAS center (ERAS group) and those treated in a non-ERAS center (non-ERAS group). Data were analyzed from June 15 through September 15, 2019. EXPOSURES Total hip or knee arthroplasty and perioperative management. Sixteen individual ERAS items were assessed in all included patients, whether they were treated at a center that was part of an established ERAS protocol or not. MAIN OUTCOMES AND MEASURES The primary outcome was postoperative complications within 30 days after surgery. Secondary outcomes included length of stay and mortality. RESULTS During the 2-month recruitment period, 6146 patients were included (3580 women [58.2%]; median age, 71 [interquartile range (IQR), 63-76] years). Of these, 680 patients (11.1%) presented with postoperative complications. No differences were found in the number of patients with overall postoperative complications between ERAS and non-ERAS groups (163 [10.2%] vs 517 [11.4%]; odds ratio [OR], 0.89; 95% CI, 0.74-1.07; P = .22). Fewer patients in the ERAS group had moderate to severe complications (73 [4.6%] vs 279 [6.1%];OR, 0.74; 95% CI, 0.56-0.96; P = .02). The median overall adherence rate with the ERAS protocol was 50.0% (IQR, 43.8%-62.5%), with the rate for ERAS facilities being 68.8% (IQR, 56.2%-81.2%) vs 50.0% (IQR, 37.5%-56.2%) at non-ERAS centers (P < .001). Among the patients with the highest and lowest quartiles of adherence to ERAS components, the patients with the highest adherence had fewer overall postoperative complications (144 [10.6%] vs 270 [13.0%]; OR, 0.80; 95% CI, 0.64-0.99; P < .001) and moderate to severe postoperative complications (59 [4.4%] vs 143 [6.9%]; OR, 0.62; 95% CI, 0.45-0.84; P < .001) and shorter median length of hospital stay (4 [IQR, 3-5] vs 5 [IQR,[4][5][6] days; OR, 0.97; 95% CI, 0.96-0.99; P < .001). CONCLUSIONS AND RELEVANCEAn increase in adherence to the ERAS program was associated with a decrease in postoperative complications, although only a few ERAS items were individually associated with improved outcomes.
BackgroundThe Hip Outcome Score (HOS) is a self-reported questionnaire evaluating the outcomes of treatment interventions for hip pathologies, divided in 19 items of activities of daily life (ADL) and 9 sports’ items. The aim of the present study is to translate and validate HOS into Spanish.MethodsA prospective and multicenter study with 100 patients undergoing hip arthroscopy was performed between June 2012 and January 2013. Crosscultural adaptation was used to translate HOS into Spanish. Patients completed the questionnaire before and after surgery. Feasibility, reliability, internal consistency, construct validity (correlation with Western Ontario and McMaster Universities Osteoarthritis Index), ceiling and floor effects and sensitivity to change were assessed for the present study.ResultsMean age was 45.05 years old. 36 women and 64 men were included. Feasibility: 13% had at least one missing item within the ADL subscale and 17% within the sport subscale. Reliability: the translated version of HOS was highly reproducible with intraclass correlation coefficient of 0.95 for ADL and 0.94 for the sports subscale. Internal consistency was confirmed with Cronbach’s alpha >0.90 in both subscales. Construct validity showed statistically significant correlation with WOMAC. Ceiling effect was observed in 6% and 12% for ADL and sports subscale, respectively. Floor effect was found in 3% and 37% ADL and sports subscale, respectively. Large sensitivity to change was shown in both subscales.ConclusionThe translated version of HOS into Spanish has shown to be feasible, reliable and sensible to changes for patients undergoing hip arthroscopy. This validated translation of HOS allows for comparisons between studies involving either Spanish- or English-speaking patients.Level of evidencePrognostic study, Level I
BackgroundThe international Hip Outcome Tool-33 (iHOT-33) is a 33-item self administered outcome measure based on a Visual Analogue Scale response format designed for young and active population with hip pathology. The aim of the present study is to translate and validate the iHOT-33 into Spanish.Methods97 patients undergoing hip arthroscopy were included in this prospective and multicenter study performed between January 2012 and May 2014. Crosscultural adaptation was used to translate iHOT-33 into Spanish. Patients completed the questionnaire before and after surgery. Feasibility, reliability, internal consistency, construct validity (correlation with Western Ontario and McMaster Universities Osteoarthritis Index), ceiling and floor effects and sensitivity to change were assessed for the present study.ResultsMean age was 48 years old. Feasibility: 41.2 % patients had no blank questions, and 71.3 % of patients had fulfilled all but one or two questions. Reliability: ICC for the global questionnaire was 0.97, showing that the questionnaire is highly reproducible. Internal consistency: Cronbach’s alpha was 0.98 for the global questionnaire. Construct validity: there was a high correlation with WOMAC (correlation coefficient >0.5). The Ceiling effect (taking into account the minimum detectable change) was 12.1 % and the floor effect was 21.6 %, for the global questionnaire. Large sensitivity to change was shown.Conclusionthe Spanish version of iHOT-33 has shown to be feasible, reliable and sensible to changes for patients undergoing hip arthroscopy. This validated translation of iHOT-33 allows for comparisons between studies involving either Spanish- or English-speaking patients.Level of evidencePrognostic study, Level I.
Femoroacetabular regularization in hip impingement is currently performed by means of trochanter osteotomy and hip dislocation or more recently by means of hip arthroscopy. We present a novel alternative through a unique mini-invasive anterior approach. Our first series consisted of 35 hips (32 patients) with a mean follow-up of 29.2 months. Range of motion (ROM) and clinical scores were evaluated preoperatively at six weeks, three months, six months and one-year follow-up (FU). Impingement test was negative in 33 out of 35 cases six weeks after surgery. Mean hospitalisation time was 2.6 days (2-5 days). Mean improvement in internal rotation was 23 degrees (p=0.006) and 21 degrees in flexion (p=0.011). There was a significant improvement in hip score according to the Merle d'Aubign evaluation (13.8 points preoperative vs. 16.9 at one-year visit) (p=0.017). No Trendelenburg, heterotopic calcifications or osteonecrosis were observed. Complications related to the femorocutaneous nerve appeared in six cases (17.1%) although all but one were neuroapraxia and disappeared before one year. Mean rehabilitation time was 4.4 weeks. We conclude that the anterior surgical approach for the treatment of femoroacetabular impingement enables early resumption of sport while accuracy in bone resection is maintained.
Surgical treatment of labral injuries has shifted from debridement to preservation over the past decades. Primary repair and secondary augmentation or reconstruction techniques are aimed at restoring the labral seal and preserving or improving contact mechanics. Currently, the standard of care for non-repairable tears favours the use of auto- or allografts. As an alternative, we present our initial experience using a synthetic, off-the-shelf polyurethane scaffold for augmentation and reconstruction of segmental labral tissue loss or irreparable labral damage. Three patients aged 37–44 (two male, one female) with femoroacetabular impingement without associated dysplasia (Wiberg > 25°) or osteoarthritis (Tönnis <2) were included in this series. Labral reconstruction (one case) and augmentation (two cases) were performed using a synthetic polyurethane scaffold developed for meniscal substitution (Actifit®, Orteq Ltd, London, UK) and adapted to the hip. Clinical results were analysed with patient-reported outcomes (PROMs) using non-arthritic hip score (NAHS) and daily live activities hip outcome score (DLA HOS) and magnetic resonance images (MRI) at 2- and 4-year follow-up. Clinically improvement was seen in all PROMs at 4 years. The NAHS scores improved from 57.7 to 82.3 (50.9% improvement) and HOS from 59 to 79.3 (35.3% improvement). Last follow-up MRIs confirmed the presence of the scaffold; however, the scaffold signal was still hyperintense compared to native labrum. There was no shrinkage in any scaffold and no progression to hip osteoarthritis seen. Reconstruction or augmentation of segmental labral defects with a polyurethane scaffold may be an effective procedure. At 4 years after implantation, our small cases series resulted in improved hip joint function, reduced pain and scaffold preservation on follow-up imaging.
