Aims

This work aimed at answering the following research questions: 1) What is the rate of mechanical complications, nonunion and infection for head/neck femoral fractures, intertrochanteric fractures, and subtrochanteric fractures in the elderly USA population? and 2) Which factors influence adverse outcomes?

Over recent years hip arthroscopic surgery has evolved into one of the most rapidly expanding fields in orthopaedic surgery. Complications are largely transient and incidences between 0.5% and 6.4% have been reported. However, major complications can and do occur. This article analyses the reported complications and makes recommendations based on the literature review and personal experience on how to minimise them.

To compare complications, survivorship and results in 2 groups of Furlong-HAP Active, one with ceramic-ceramic and the other with metal-XLPE friction pair. Prospective, non-randomized, comparison of 2 series of JRI uncemented prosthesis, implanted with identical protocol by 1 surgeon in 1 hospital from 2006 to 2014. Friction pair was ceramic (Biolox Forte or Delta) in 35 patients of 53.7+/−10.6 years (25–69) (21 males, 60%), and CrCo-XLPE in 65 cases of 69.0+/−8.9 years (42–81) (36 males, 55%); there were significant differences in age (p<0.00001) but not in sex (p=0.6565). Head diameter: Ce-Ce with 19 of 28mm, 9 of 32 and 7 of 36mm; Me-PE with 63 of 28mm, 1 of 32 and 1 of 36. Follow-up averaged 10.5+/−3.1 years (1–15) in ceramic and 9.8+/−3.8 years (2–15) in XLPE group. Pearson, Fisher, Kolmogorov-Smirnov, Student, Mann-Whitney, calculated with the informatic tools Microsoft Excel 2007 and . https://www.socscistatistics.com/tests/. . Complications in ceramic joints: 2 late infections (Fisher exact test=0.6101) (1 DAIR, 1 one-stage exchange); 1 dislocation (Fisher exact test=0.2549) (closed reduction); 1 Vancouver C fracture (ORIF) (Fisher exact test=0.6548). Complications in Me-XLPE joints: 2 late infections (Fisher=0.6101) (1 DAIR, 1 two-stage exchange); 7 dislocations (Fisher=0.2549) (2 early, open reduction) (5 late: 3 closed reduction, 1 cup revision, 1 constrained cup); 4 Vancouver B fractures (Fisher=0.6548) (2 intraoperative, cerclages; 2 late, exchange). Final follow-up: Harris Hip Score averaged 93.2+/−13.7 (23–100) in ceramic and 94.3+/−8.7 (65–100) in XLPE joints (p=0.64552). Wear: 0.06+/−0.38mm (0–1.5) in ceramic and 0.16+/−0.5mm (0–2) in Me-PE THAs (p=0.30302). Osteolysis in Charnley-De Lee zones: 8 zones (6 patients) (17%) in ceramic cups, 25 zones (15 patients) (23%) in XLPE cups (p=0.980127). Survivorship without any surgery or closed reduction after 15 years: 91.0% in ceramic joints, 83.8% in Me-XLPE joints. Survivorship without component exchange after 15 years: 93.9% in ceramic joints, 93.6% in Me-XLPE joints. At least after 10 years follow-up of Furlong-HAP Active, metal-XLPE and ceramic-ceramic joints present no significant differences in complications, clinical score, wear, acetabular osteolysis, or survivorship without component exchange. On the contrary, survivorship without any surgery or closed reduction is different because of the high rate of dislocation in 28mm metal-poly joints

Introduction. Prosthetic joint infection (PJI) is an devastating complication after total hip arthroplasty (THA). The common treatment in the US is a two-stage exchange which can be associated with significant morbidity and mortality. The purpose of this study was to analyze complications in the treatment course of patients undergoing two-stage exchange for PJI THA and determine when they occur. Methods. We analyzed all patients that underwent two-stage exchange arthroplasty for treatment of PJI after THA from January 2005 – December 2017 at a single institution. Complications were categorized as medical or surgical, divided into three intervals: (1) inter-stage, (2) early post-reimplantation (<90 days) and (3) late post-reimplantation (> 90 days). Minimum follow up was one year. Success was based on the Musculoskeletal Infection Society (MSIS) definition. Results. 185 hips underwent first stage of planned two stage exchange. The median age was 65 (IQR 18). There were 93 males and 92 females. 73 patients had a complication during treatment. 13.5% (25/185) of patients experienced a medical complication and 28.1% (52/185) a surgical complication. There was a 14.1% (26/185) mortality at a median of 2.5 years (IQR 4.9). 51(29%) had complications during the interstage period, most common being recurrence of infection requiring a spacer exchange (48.6%). 2 patients died and 2 patients failed to progress to the second stage. 22(12%) complications following re-implantation, most commonly persistence /recurrence of infection (31%). 183/185 patients that initiated a two stage exchange were re-implanted, only 65% (120/185) were successfully treated with or without antibiotic suppression at one-year without additional surgery. Conclusions. While 2 stage exchanges for PJI in THA have been reported as successful, there are few reports of the complications during the process. In our series, significant numbers of patients experienced complications, often during the interstage period, highlighting the morbidity of this method of treatment

Introduction. Increasingly, patients with bilateral hip arthritis wish to undergo staged total hip arthroplasty. With the rise in demand for arthroplasty perioperative risk assessment and counseling is critical for shared decision making; however, it is unknown if complications that occur after a unilateral hip arthroplasty predict complications following surgery of the contralateral hip. Methods. We used nation-wide linked discharge data from the Hospital Cost and Utilization Project from 2005–2014 to analyze the incidence and recurrence of complications following the first and second stage operations in staged bilateral total hip arthroplasty (BTHAs). Complications included perioperative risks within 30–60 days, and infection and mechanical complications within one year. Conditional probabilities and odds ratios were calculated to determine whether experiencing a complication after the first stage of surgery increased the risk of developing the same complication after the second stage. Results. 13,829 patients who underwent staged BTHAs were analyzed. For 6 of the 11 outcomes evaluated, patients who experienced the outcome following the first arthroplasty had a significantly increased probability and odds of developing that same complication following the second arthroplasty, compared to those who did not experience the complication after the first surgery. This was true for digestive complications (OR=25.67, 95% CI=13.86–46.08, p<0.001), hematoma (OR=12.17, 95% CI=4.55–31.14, p<0.001), deep vein thrombosis (OR=4.82, 95% CI=2.34–9.65, p<0.001), pulmonary embolism (OR=12.03, 95% CI=2.02–46.77, p=0.01), hip infection (OR=2439.48, 95% CI=836.73–6759.85, p<0.001), and mechanical malfunction (OR=117.49, 95% CI=91.55–150.34, p<0.001). Conclusions. The occurrence of certain complications after unilateral total hip arthroplasty is associated with an increased risk that the same complication will occur after staged replacement of the contralateral hip. Patients who experience these complications after unilateral hip arthroplasty should be appropriately counseled regarding their risk profile prior to undergoing staged contralateral hip arthroplasty. Level of Evidence: Therapeutic Level III. Keywords: hip arthroplasty; bilateral; staged; joint replacement

While obesity is associated with an increased risk of complications after total hip arthroplasty (THA) the relationship between body mass index (BMI) and the risk of early postoperative complications has not been fully characterized. This study sought to describe the relationship between BMI and the risk of early postoperative complications, including periprosthetic joint infection (PJI), composite surgical, and composite medical complications.

Primary, elective THAs performed from 2016–2021 were identified using the Premier Healthcare Database (PHD). The study's primary outcome was the diagnosis of PJI within 90 days of THA. Using BMI as a continuous variable, logistic regression was used to develop restricted cubic splines (RCSs) to determine the impact of BMI on PJI risk. Bootstrap simulation was used to identify an inflection point in the final RCS model. The same technique was used to characterize the effects of BMI on composite medical and surgical complications.

We found that PJI risk increased exponentially beyond a BMI cutpoint of 37.4 kg/m². Relative to the cutpoint, patients with a BMI of 40 or 50 kg/m² were at a 1.22- and 2.55-fold increased risk of developing PJI, respectively. Surgical complications increased at a BMI of 32 kg/m² and medical complications increased at a BMI of 39 kg/m². Relative to these cutpoints, patients with a BMI of 50 kg/m² were at a 1.36- and 2.07-fold increased risk of developing medical and surgical complications, respectively.

The results of this study indicate a non-linear relationship between patient BMI and early postoperative risk of PJI, composite medical complications, and composite surgical complications following THA. The identified cutpoints with associated odds ratios can serve as tools to help risk-stratify and counsel patients seeking primary THA.

Although arthroscopy of the hip is being carried out increasingly, little is known about the rate of associated complications. We describe a prospective study of 640 consecutive procedures in which a consistent technique was used. The overall complication rate was 1.6%. Complications, none of which was major or long-term, included transient palsy of the sciatic and femoral nerves, perineal injury, bleeding from the portal wounds, trochanteric bursitis and intra-articular breakage of the instrument. We believe that it is possible to undertake this operation safely using the technique described

Hip arthroscopy (HA) is an effective treatment for various hip conditions but has a steep learning curve and its effect on long-term joint preservation is unclear. This study uses population-level data to assess (1) the 90-day complication rate, and (2) the frequency and timing of revision HA, total hip replacement (THR), and pelvic osteotomy (PO) following primary HA.

We performed a retrospective analysis of the National Hospital Episode Statistics database, examining all patients who underwent primary HA in NHS hospitals in England from 2010 to 2023 using relevant OPCS-4 codes. We evaluated patient demographics, 90-day complications, and reoperation rates for revision HA, THR, and PO. Descriptive statistical analyses were performed to calculate frequencies and average time to reoperations.

We included 22,401 HA procedures in the study. The mean LOS was 0.82±2.04 days. The 90-day readmission rate was 0.17% at a mean of 54.4±8.1 days. The most common reasons for readmission were reoperation (0.071%), followed by infection (0.031%), pulmonary embolism (0.027%), pain (0.022%), bleeding (0.018%), and deep vein thrombosis (0.004%). One patient died within 90 days.

Overall, 4942 patients (22.1%) required further surgery at a mean of 2.71±2.27 years. The rates of revision HA, conversion to THR, and PO were 6.94%, 14.6%, and 0.50% at a mean of 2.39±1.79, 2.87±2.46, and 2.26±1.80 years respectively. Female patients had higher rates of reoperation than males for conversion to THR (9.99% vs 4.63%), revision HA (4.92% vs 2.02%), and subsequent PO (0.43% vs. 0.06%) (p<0.001).

This study demonstrates a low short-term complication rate after primary HA, supporting existing literature. However, a large proportion of patients required further surgery, especially females. These findings highlight the need for careful patient selection and counselling before HA to optimise outcomes, as well as further research on factors influencing longer-term outcomes and cost-effectiveness.

Hip dysplasia is a common cause of hip pain in young adults. Pelvic osteotomy (PO) techniques are the gold standard for treating symptomatic patients, albeit technically demanding. This study aimed to (1) evaluate the 90-day complication rate, and (2) investigate the reasons, frequency and timing of reoperations following primary PO procedures.

We retrospectively analysed the National Hospital Episode Statistics database, examining all patients aged over 14 who underwent PO in NHS England hospitals from 2010 to 2023. We identified index procedures and reoperations using relevant OPCS-4 codes. We analysed patient demographics, 90-day complications, and readmission rates for ipsilateral metalwork removal, revision PO, hip arthroscopy (HA), and THR conversion, and calculated the mean time to reoperations.

This study included 1,348 PO cases (mean age: 28.7±9.1 years, 89.5% female). The mean hospital stay was 5.4±3.9 days, with a 90-day readmission rate of 0.52% at a mean of 51.0±17.2 days. The most common causes were infection (0.22%) and reoperation (0.15%). The 90-day rate of pulmonary embolism and deep vein thrombosis was 0.074%. One patient died within 90 days.

Overall, 810 patients (60.1%) were readmitted for a subsequent hip procedure at a mean of 2.12±1.90 years following their primary PO. Metalwork removal was required in 616 patients (45.7%) at a mean of 1.70±1.19 years. Readmission rates for revision PO, HA, and THR, were 4.23% (mean time: 2.89±0.82 years), 4.15% (mean time: 2.91±2.28 years) and 6.01% (mean time: 5.24±3.08 years) respectively.

This study highlights a low 90-day complication rate following primary PO, but a high reoperation rate, mainly for metalwork removal. We provide the most up-to-date report of revision PO, HA and THR conversion rates in England. These findings provide valuable insight that can facilitate informed decision-making, expectation-setting, and post-operative planning, also establishing a benchmark for future quality improvement.

Introduction

With the widespread legalization of cannabis across the United States, well-powered studies evaluating the impact of cannabis use disorder on outcomes following primary total hip arthroplasty are warranted. Therefore, the aim of this study was to determine whether cannabis use disorder has an effect on patients who undergo primary hip arthroplasty in terms of: 1) hospital lengths of stay (LOS); 2) medical complications; 3) implant-related complications; and 4) costs of care.

Aims

The number of patients undergoing arthroscopic surgery of the hip has increased significantly during the past decade. It has now become an established technique for the treatment of many intra- and extra-articular conditions affecting the hip. However, it has a steep learning curve and is not without the risk of complications. The purpose of this systematic review was to determine the prevalence of complications during and following this procedure.

Purpose

Obesity has previously been demonstrated to be an independent risk factor for increased complications following total hip (THA) and total knee arthroplasty (TKA). The purpose of this study was to compare the effects of obesity and BMI to determine whether the magnitude of the effect was similar for both procedures.

Aims

Dislocation remains a leading cause of failure following revision total hip arthroplasty (THA). While dual-mobility (DM) bearings have been shown to mitigate this risk, options are limited when retaining or implanting an uncemented shell without modular DM options. In these circumstances, a monoblock DM cup, designed for cementing, can be cemented into an uncemented acetabular shell. The goal of this study was to describe the implant survival, complications, and radiological outcomes of this construct.

Obesity has previously been demonstrated to be an independent risk factor for increased complications following total hip (THA) and total knee arthroplasty (TKA). The purpose of this study was to compare the effects of obesity and BMI to determine whether the magnitude of the effect was similar for both procedures.

We queried the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database to identify patients who underwent primary THA or TKA between 2010 and 2014. Patients were stratified by procedure and classified as non-obese, obese, or morbidly obese according to BMI. Thirty-day rates of wound complications, deep infection, total complications, and reoperation were compared using univariate and multivariate logistic regression analyses.

We identified 64,648 patients who underwent THA and 97,137 patients who underwent TKA. Obese THA patients had significantly higher rates of wound complications (1.53% vs 0.96%), deep infection (0.31% vs 0.17%), reoperation rate (2.11% vs 1.02%), and total complications (5.22% vs. 4.63%) compared to TKA patients. Morbidly obese patients undergoing THA were also found to have significantly higher rates of wound complications (3.25% vs 1.52%), deep infection (0.84% vs 0.23%), reoperation rate (3.65% vs 1.60%), and total complications (7.36% vs. 5.57%). Multivariate regression analysis identified increasingly higher odds of each outcome measure as BMI increased.

This study demonstrates the impact of obesity on postoperative complications is more profound for THA than TKA. This emphasizes the importance of considering patient comorbidities in the context of the specific procedure (hips and knees should be analyzed independently) when assessing risks of surgery.

Aims

Adult patients with history of childhood infection pose a surgical challenge for total hip arthroplasty (THA) due to distorted bony anatomy, soft-tissue contractures, risk of reinfection, and relatively younger age. Therefore, the purpose of the present study was to determine clinical outcome, reinfection rate, and complications in patients with septic sequelae after THA.

Introduction

The direct anterior approach (DAA) for total hip arthroplasty (THA) has gained popularity in recent years. Potential advantages over other surgical approaches include less postoperative pain, fewer postoperative precautions, and quicker early recovery. It is most commonly performed in the supine position with traction tables or table mounted bone hooks to facilitate exposure. In this study, we describe a reproducible surgical technique for DAA THA in the lateral decubitus position with use of standard THA equipment and report on our results and learning curve.

Introduction

Previous studies have indicated that prolonged surgical time may lead to higher rates of infection following total hip arthroplasty (THA). The purpose of this study was to evaluate the influence of surgical time on 30-day complications following THA and to determine if there was a time interval associated with worse outcomes.

Introduction

Total hip arthroplasty (THA) is gaining popularity as a treatment for displaced femoral neck fractures (FNF), especially in physiologically younger patients. While elective THA for primary osteoarthritis (OA) has demonstrated low rates of complications and readmissions, the outcomes of THA for FNF are less predictable. Additionally, these THA procedures are equally included in various alternative payment bundles. Therefore, the aim of this study is to assess postoperative complication rates after THA for primary OA compared with FNF.

Aims

Lateral femoral cutaneous nerve (LFCN) injury is a potential complication after the direct anterior approach for total hip arthroplasty (DAA-THA). The aim of this study was to determine how the location of the fasciotomy in DAA-THA affects LFCN injury.

Background

The acknowledged benefit of the direct anterior (DA) approach is early functional return. Most surgeons in the U.S. use cementless femoral replacement given the negative track record of some cemented designs. However, delayed osseointegration of a femoral stem typically seen in older patients with poor bone quality will delay recovery, diminishing the benefits of the DA approach. Registry studies have shown a higher revision rate and complications in this patient population leading to a renewed interest in cemented fixation.
