Total Hip Arthroplasty in Patients Younger than 35 Is Effective Regardless of Surgical Approach

AbstractDespite the increasing frequency of younger patients undergoing total hip arthroplasty (THA), very few, if any, studies report on postoperative outcomes that specifically compare the two most commonly used approaches in this age group. The purpose of our study is to assess whether surgical approach affects postoperative outcomes in THA patients younger than 35 years. A retrospective analysis of 115 patients younger than 35 years that underwent primary unilateral THA between January 2013 and April 2018 was conducted. Patients were divided into two cohorts: (1) patients that underwent THA utilizing the anterior approach and (2) patients that underwent THA utilizing the posterior approach. Subanalysis controlling for surgical case complexity and use of robotic assistance was performed. Radiographic analysis included measurement of perioperative leg length discrepancies. Of the total 115 patients, 37 were in the anterior THA cohort, and 78 were in the posterior THA cohort. All baseline patient characteristics were similar among both cohorts. Patients in the anterior THA cohort had shorter mean operative times (95 vs. 121 minutes; p < 0.01) and shorter mean hospital length of stay or LOS (1.9 vs. 2.8 days; p < 0.01). Leg length discrepancies, dislocation, revision, and all-cause postoperative complication rates were similar between both cohorts. When excluding complex cases and use of robotic assistance (anterior n = 36, posterior n = 39), there was no difference in operative time, LOS, or postoperative outcomes. Our study suggests that surgically complex patients were more likely to undergo posterior rather than anterior THA. When controlling for surgical complexity and use of robotic assistance, no difference between approach with respect to operative time, hospital LOS, dislocation, revision, and all-cause postoperative surgical complication rates in THA recipients under 35 years of age was found. The results suggest that the anterior and posterior approaches can be equally effective for the majority of young THA patients.

Background: As the incidence of primary total hip arthroplasty (THA) continues to increase, revision THA (rTHA) is becoming an increasingly common procedure. rTHA is widely regarded as a more challenging procedure, with higher complication rates and increased medical, social and economic burdens when compared to its primary counterpart. Given the complexity of rTHA and the projected increase in incidence of these procedures, patient optimisation is becoming of interest to improve outcomes. Anaesthetic choice has been extensively studied in primary THA as a modifiable risk factor for postoperative outcomes, showing favourable results for neuraxial anaesthesia compared to general anaesthesia. The impact of anaesthetic choice in rTHA has not been studied previously. Methods: A retrospective study was performed using the American College of Surgeons National Surgical Quality Improvement Program database. Patients who underwent rTHA between 2014 and 2017 were divided into 3 anaesthesia cohorts: general anaesthesia, neuraxial anaesthesia, and combined general-regional (neuraxial and/or peripheral nerve block) anaesthesia. Univariate and multivariate analyses were used to analyse patient characteristics and 30-day postoperative outcomes. Bonferroni correction was applied for post-hoc analysis. Results: In total, 5759 patients were identified. Of these, 3551 (61.7%) patients underwent general anaesthesia, 1513 (26.3%) patients underwent neuraxial anaesthesia, and 695 (12.1%) patients underwent combined general-regional anaesthesia. On multivariate analysis, neuraxial anaesthesia was associated with decreased odds for any-one complication (OR 0.635; p < 0.001), perioperative blood transfusion (OR 0.641; p < 0.001), and extended length of stay (OR 0.005; p = 0.005) compared to general anaesthesia. Conclusions: Relative to those receiving general anaesthesia, patients undergoing neuraxial anaesthesia are at decreased risk for postoperative complications, perioperative blood transfusions, and extended length of stay. Prospective controlled trials should be conducted to verify these findings.

Background: Although total hip arthroplasty (THA) is among the most successful orthopaedic procedures, it is not without complications. As such, finding the optimal surgical approach has become an area of particular interest. In this study, we compare: (1) pain intensity; (2) opioid consumption; (3) lengths of stay (LOS); (4) complication rates; (5) discharge destination; and (6) ambulatory function between patients who underwent THA via the supine muscle-sparing anterolateral (MS-ALA) and conventional direct lateral (DLA) approaches. Methods: A retrospective analysis was conducted on 220 consecutive patients who received primary THA using the supine MS-ALA ( n = 101) or DLA ( n = 119) between 1 January 2014 and 31 December 2016. Outcomes included postoperative pain intensity, opioid consumption, LOS, discharge destination, complications, additional procedures, and time to independent ambulation. Results: We demonstrated significantly lower opioid consumption on postoperative days (POD) 1 and 2 (mean differences, −32.0 and −28.4 mg, respectively; p ⩽ 0.001) and decreased pain intensity during the second 24 hours of the hospital stay (mean difference, –22.0; p < 0.001) in patients receiving the MS-ALA. Relative to the DLA cohort, patients in the MS-ALA cohort were 2.04 times more likely to be discharged to home ( p = 0.028) and 1.91 times less likely to experience postoperative abductor insufficiency ( p = 0.039). Conclusion: The present study is the 1st to compare postoperative outcomes, particularly pain intensity and opioid consumption, between the supine muscle-sparing anterolateral and direct lateral THA approaches. Further research should investigate the effect of surgical approach on quality and cost of care, include larger sample sizes, and involve longer-term follow-up.

Abstract Background: Venous thromboembolism (VTE) remains a major complication after total hip arthroplasty (THA), irrespective of the surgical approach. This study investigated the incidence of VTE in patients undergoing THA through intermuscular minimally invasive surgical techniques, which included a direct anterior approach (DAA), an anterolateral approach (AL), and anterolateral supine approach (ALS), at a single institution. Methods: One hundred consecutive patients treated with each surgical approach were evaluated. Plasma D-dimer levels 1 month preoperatively and 1 day postoperatively, operative time, and intraoperative blood loss were recorded, and the presence of VTE was evaluated based on multidetector row computed tomography performed the day after surgery. Student’s t-test and Pearson’s chi-square test or one-way analysis of variance were used in statistical analysis. Results: No differences among the groups in terms of age, height, weight, operative time, intraoperative bleeding, and preoperative and postoperative D-dimer levels were observed. The overall incidence of VTE was 21%. The incidences of VTE were 30% in AL, 17% in ALS, and 16% in DAA, representing a significantly higher rate in AL than in ALS and DAA (P=0.025). The incidences of VTE on the operated side were 19% in AL, 13% in ALS, and 12% in DAA, with no statistically significant differences. The incidences of VTE on the non-operated side were 22% in AL, 9% in ALS, and 8% in DAA; these differences were statistically significant (P=0.0045). Conclusions: Results showed that the incidence of VTE was significantly higher in AL than in ALS and DAA, especially for the non-operated side.

Background: Long operative times in total hip arthroplasty (THA) have been shown to be associated with increased risk of revision as well as perioperative morbidity. This study assesses the effect of extended operative times on complication rates following primary THA using the most recent national data. Methods: The National Surgical Quality Improvement Program (NSQIP) database (2008–2016) was queried for primary THA. Groups were defined by operative time 1 standard deviation (1 SD) above the mean. Univariate, propensity score-matched, and multivariate logistic regression analyses were performed to evaluate outcomes. Results: Data was available for 135,013 THA patients. Among these groups, mean operative time in the extended operative time group was 166 minutes (compared with 82 minutes). Patients undergoing longer operative times were 3.8 years younger, had a 1.5 kg/m2 higher body mass index and had a 0.5 day longer mean length of stay. Propensity matching identified 16,123 pairs for analysis in the 1 SD group. Longer operative time led to 173% increased risk of major medical morbidity, 140% increased likelihood of length of stay greater than 5 days, 59% increased risk of reoperation, 45% increased risk of readmission, and a 30% decreased likelihood of return to home postoperatively. There was no increased risk of death within 30 days. Conclusion: Long operative times were associated with increases in multiple postoperative complications, but not mortality. Surgeons should be advised to take steps to minimise operative time by adequate preoperative planning and optimal team communication.

Abstract BackgroundHip surgeons performing total hip arthroplasty (THA) through the direct anterior approach (DAA) commonly use a traction table to facilitate exposure. Even though performing THA through DAA without traction table could be technically more demanding, this technique offers the advantage of intraoperative leg length comparison. Therefore, this study aimed to compare clinical outcomes, complication rates, component positioning and leg length discrepancy (LLD) after THA through the DAA performed with or without a traction table.MethodsA single-surgeon continuous series of 75 patients who underwent DAA THA performed with a traction table were matched for gender, age and BMI with 75 patients who underwent DAA THA performed without a traction table (male:62, female:88, with an average age of 68 y.o). Clinical and radiological outcomes, intra- and post-operative complications and LLD were retrospectively assessed.ResultsNo statistically significant difference was detected in surgical time, hospital stay, Harris Hip Score (HHS), complication rates, and implant positioning between the two groups. Leg length restoration was significantly more accurate in the group performed without a traction table (2.4 ± 2 mm vs. 3.7 ± 3.1 mm, respectively; p value ≤ 0.05). No LLD > 10 mm was reported in the group performed without traction table, whereas two cases (2.7 %) were reported in those performed with traction table.ConclusionPerforming THA through DAA without a traction table was associated with a significantly more accurate leg length restoration without significantly increase in the rates of intra- and post-operative complications.

Navigated Surgery

Two-dimensional (2D) planning on standard radiographs for total hip arthroplasty may not be sufficiently accurate to predict implant sizing or restore leg length and femoral offset, whereas 3D planning avoids magnification and projection errors. Furthermore, weightbearing measures are not available with computed tomography (CT) and leg length and offset are rarely checked postoperatively using any imaging modality. Navigation can usually achieve a surgical plan precisely, but the choice of that plan remains key, which is best guided by preoperative planning. The study objectives were therefore to (1) evaluate the accuracy of stem/cup size prediction using dedicated 3D planning software based on biplanar radiographic imaging under weightbearing and (2) compare the preplanned leg length and femoral offset with the postoperative result. This single-centre, single-surgeon prospective study consisted of a cohort of 33 patients operated on over 24 months. The routine clinical workflow consisted of preoperative biplanar weightbearing imaging, 3D surgical planning, navigated surgery to execute the plan, and postoperative biplanar imaging to verify the radiological outcomes in 3D weightbearing. 3D planning was performed with the dedicated hipEOS® planning software to determine stem and cup size and position, plus 3D anatomical and functional parameters, in particular variations in leg length and femoral offset. Component size planning accuracy was 94% (31/33) within one size for the femoral stem and 100% (33/33) within one size for the acetabular cup. There were no significant differences between planned versus implanted femoral stem size or planned versus measured changes in leg length or offset. Cup size did differ significantly, tending towards implanting one size larger when there was a difference. Biplanar radiographs plus hipEOS planning software showed good reliability for predicting implant size, leg length, and femoral offset and postoperatively provided a check on the navigated surgery. Compared to previous studies, the predictive results were better than 2D planning on conventional radiography and equal to 3D planning on CT images, with lower radiation dose, and in the weightbearing position.

Staged Reconstruction

Abstract Background and purpose Total hip arthroplasty (THA) is a successful approach to treat unilateral symptomatic neglected hip dislocation (NHD). However, the extensive leg length discrepancy (LLD) can hereby only be partially corrected. In case of residual LLD of more than 2 cm, subsequent femoral lengthening can be considered. Patients/material/methods Retrospective analysis of clinical data and radiographs of five patients (age 38.1 (28–51) years) with unilateral NHD who underwent THA with (n = 3) or without (n = 2) subtrochanteric shortening osteotomy (SSO) and secondary intramedullary femoral lengthening through a retrograde magnetically-driven lengthening nail (follow-up 18.4 (15–27) months). Results LLD was 51.0 (45–60) mm before and 37.0 (30–45) mm after THA. Delayed bone union at one SSO site healed after revision with autologous bone grafting and plate fixation. Subsequent lengthening led to leg length equalisation in all patients. Complete consolidation was documented in all lengthened segments. Conclusion Staged reconstruction via THA and secondary femoral lengthening can successfully be used to reconstruct the hip joint and equalise LLD. The specific anatomical conditions have to be taken into consideration when planning treatment, and patients ought to be closely monitored.
