Aims. The aim of this study was to investigate the outcomes of Vancouver type B2 and B3 fractures by performing a systematic review of the methods of surgical treatment which have been reported. Materials and Methods. A systematic search was performed in Ovid MEDLINE, Embase and the Cochrane Central Register of Controlled Trials. For inclusion, studies required a minimum of ten patients with a Vancouver type B2 and/or ten patients with a Vancouver type B3 fracture, a minimum mean follow-up of two years and outcomes which were matched to the type of fracture. Studies were also required to report the rate of re-operation as an outcome measure. The protocol was registered in the PROSPERO database. . Results. A total of 22 studies were included based on the eligibility criteria, including 343 B2 fractures and 167 B3 fractures. The mean follow-up ranged from 32 months to 74 months. . Of 343 Vancouver B2 fractures, the treatment in 298 (86.8%) involved revision arthroplasty and 45 (12.6%) were treated with internal fixation alone. A total of 37 patients (12.4%) treated with revision arthroplasty and six (13.3%) treated by internal fixation only underwent further re-operation. . Of 167 Vancouver B3 fractures, the treatment in 160 (95.8%) involved revision arthroplasty and eight (4.8%) were treated with internal fixation without revision. A total of 23 patients (14.4%) treated with revision arthroplasty and two (28.6%) treated only with internal fixation required re-operation. Conclusion. A significant proportion, particularly of B2 fractures, were treated without revision of the stem. These were associated with a higher rate of re-operation. The treatment of B3 fractures without revision of the stem resulted in a high rate of re-operation. This demonstrates the importance of careful evaluation and accurate characterisation of the fracture at the time of presentation to ensure the correct management. There is a need for improvement in the reporting of data in case series recording the outcome of the surgical treatment of periprosthetic fractures. We have suggested a minimum dataset to improve the quality of data in studies dealing with these fractures. Cite this article: Bone Joint J 2017;99-B(4 Supple B):17–25

Although total hip arthroplasty (THA) is beneficial for many patients with hip osteoarthritis (OA), a subset of patients experience minimal benefit. It is therefore pertinent to understand the predictors of poor functional outcome to facilitate shared decision making. One such predictor is preoperative radiographic OA severity. The aim of this systematic review was to determine whether preoperative radiographic OA severity could predict postoperative patient-reported outcome measures (PROMs) and satisfaction rates after THA. This systematic review was conducted according to PRISMA guidelines, and the protocol published in PROSPERO (ID:Â CRD42023445918). A literature search was performed using Embase, MEDLINE and Cochrane Library databases. Demographics, radiographic OA severity, PROMs, satisfaction, and complications after THA were collected. A meta-analysis was performed, where appropriate, using a random-effects model. Of 631 identified articles, 12 were included in the final analysis (8,034 participants; mean age 65.2, 38.1% male, mean BMI 29.1 kg/m2). There were three key findings. Firstly, those with mild OA are less likely to achieve a meaningful clinical improvement in PROMs (odds ratio (OR) 0.50, 95% confidence interval (CI) 0.38, 0.65; p < 0.00001). Secondly, two studies indicates that postoperative patient satisfaction was lower in participants with mild OA. Thirdly, participants with mild arthritis experience less improvement in SF-36 physical functioning (mean difference (MD) -8.31, 95% CI -10.97, -5.64; p < 0.00001) and role physical (MD -5.59, 95% CI -8.40, -2.77; p < 0.0001), but showed higher improvement in general health (MD 1.68, 95% CI 0.31, 3.06; p = 0.02). Patients with mild OA, as determined radiographically, are less likely to achieve meaningful clinical improvements in PROMs and have lower postoperative satisfaction after THA. This information will improve collaborative decision-making in the preoperative period

In this study, we examined the impact of dual-mobility (DM) versus fixed-bearing (FB) implants on outcomes following total hip arthroplasty (THA), a common and successful operation. We examined all-cause revision, revision due to dislocation, postoperative complications and functional scores in patients undergoing primary and revision THA. A systematic review was performed according to PRISMA guidelines, and was registered in PROSPERO (ID CRD42023403736). The Cochrane Library, Embase, MEDLINE, Web of Science, and Scopus were searched from inception to 12th March 2023. Eligible studies underwent meta-analysis and methodological assessment using the ROBINS-I tool. Data were pooled using a random-effects maximum-likelihood model. Eight comparative, non-randomised studies involving 2,810 DM implants and 3,188 FB implants were included. In primary THA, the difference in all-cause revision was imprecise (OR 0.82, 95% CI 0.25–2.72), whilst the DM cohort had a statistically significant benefit in revision due to dislocation (OR 0.08, 95% CI 0.02–0.28). In revision THA, the DM cohort showed significant benefit in all-cause revision (OR 0.57, 95% CI 0.31–1.05) and revision due to dislocation (OR 0.14, 95% CI 0.04–0.53). DM implants were associated with a lower incidence of implant dislocation and infection. Functional outcome analysis was limited due to underreporting. No intraprosthetic dislocations were observed. The results suggest that contemporary DM designs may be advantageous in reducing the risk of all-cause revision, revision due to dislocation, and postoperative complication incidence at mid-term follow-up. Further high-quality prospective studies are needed to evaluate the long-term performance of this design, especially in revision cases

Severe heterotopic ossification (grade III and IV) after contemporary total hip arthroplasty (THA) requiring excision is very uncommon. We performed a systematic review of the literature, and report a new case series with operative treatment after primary uncemented THA. A systematic review identified papers describing patients who had excision of heterotopic ossification (HO) after contemporary THA, defined as performed after 1988. Concepts of hip arthroplasty, heterotopic ossification, and surgical excision were searched in MEDLINE, Embase, and Scopus, from database inception to November 2022. Inclusion criteria were: articles that included specific patient data on grade of heterotopic ossification, operative procedure, and prophylaxis. Studies were screened for inclusion by two independent reviewers. Extracted data included demographic data, interval from index surgery to excision, clinical results, and complications. One surgeon performed reoperation for ankylosis of primary THA in three patients with severe pain and deformity. Seven case series or case report studies were included. There were 41 patients, with grade III or IV HO, that had excision, and in five patients, revision of a component was also performed. Perioperative prophylaxis was irradiation alone in 10 patients, irradiation and indomethacin in 10, and indomethacin alone in 21 patients. At a mean follow-up time of 14.8 months, definition of the results was not uniform, and range of motion was improved, but relief of pain was inconsistent. There was one dislocation, one gastrointestinal complication, and two recurrences. Treatment of the three patients, with wide excision of peri-articular bone, selective exchange of components, and peri-operative irradiation prophylaxis, was successful in improving motion and deformity. There is insufficient data on the treatment of severe symptomatic HO after contemporary THA. Prophylaxis with low-dose irradiation was successful to prevent recurrence. Multicenter studies will be needed to determine the optimum timing and prognosis for treatment

There are a number of patients in whom hip preservation surgery is not indicated as they have developed signs of early osteoarthritis, and nor can they have a hip replacement as they are too early in the disease process. The use of PRP in OA of the hip has not been studied systematically and this study concisely collates all the available data in the use of PRP in Hip OA. This systematic review and meta-analysis aimed to assess intra-articular platelet-rich plasma as a therapeutic intervention for hip osteoarthritis, including the duration of efficacy, influence of dose and composition of PRP, and the incidence of adverse effects. We performed literature searches on the MEDLINE, EMBASE, CINHAL, WEB OF SCIENCE, COCHRANE and SCOPUS databases, and PRSIMA guidelines were followed. Data was pooled using random effects meta-analysis. We assessed quality of the included studies using the Methodological Index for Non-Randomised Studies (MINORS) instrument, with an additional assessment for Randomised Controlled Trials with the Revised Cochrane risk-of-bias tool for randomized trials (RoB 2). Eight studies were included in the analysis, with data from a total of 331 patients. PRP significantly reduced pain compared to baseline at multiple timepoints, with the greatest effect at 1–2mo follow-up. PRP only significantly improved function at the 1–2mo follow-up. A significantly larger reduction in pain was achieved with a single injection or PRP compared to multiple injections, a total injected dose of PRP <15mL compared to ≥15mL or using a leukocyte-poor PRP preparation compared to leukocyte-rich PRP. There were no lasting adverse effects. Low and moderate quality evidence suggests that PRP reduces pain and improves function at endpoint compared to baseline. Moderate quality evidence suggests a larger reduction in pain is achieved with a single injection of PRP compared to multiple injections, and low quality evidence attributes a larger reduction of pain with a total injected dose of PRP <15mL compared to ≥15mL or using leukocyte-poor PRP compared to leukocyte-rich PRP

The Exeter. ™. V40 cemented polished tapered stem system has demonstrated excellent long-term outcomes. This paper presents a systematic review of the existing literature and reports on a large case series comparing implant fractures between the Exeter V40 series; 125 mm and conventional length stem systems. A systematic literature search was performed adhering to PRISMA criteria. In parallel we performed a retrospective single centre study of Exeter. ™. V40 femoral stem prosthetic fractures between April 2003– June 2020. There are 25 reported cases of such prosthetic fractures confined to small case series and case reports within the literature. We report an additional 19 cases to the literature (mean age 66.3 ± 11.7 years; 12 female [63%]; body mass index 32.9 ± 5.9 kg/m. 2. ). The mean time from index procedure to fracture was 7.8 years (2.5–16.3, ±3.6). Exeter V40 stem fracture incidence was 0.27%. Incidence was significantly higher in 125 mm length stems compared to ≥150 mm length stems (1.26% vs 0.13%, respectively, p <0.001) and revision arthroplasty (1.209% vs 0.149%, p <0.001). When comparing different stem length cohorts, 125-mm short-stem were associated with stem body fractures (92% vs 29%, p = 0.0095), earlier time to fracture (6.2 vs 11.0 years, p = 0.0018), younger patient age at time of fracture (62.7 vs 72.6 years old, p = 0.037) and female sex (75% vs 43%, p = 0.33). This case series in conjunction with the systematic review provides evidence stem morphology plays a role in femoral implant fracture. This complication remains rare, although we report a significantly higher incidence at up to 17 years follow-up than in the literature. As femoral geometries remain the same, increasing BMIs in THR patients should raise concern. Short 125 mm length Exeter V40 stems undoubtedly have a role in restoring anatomy and biomechanics in smaller femoral geometries, although the surgeon has to appreciate the higher risk of stem fracture and the associated predisposing factors which may necessitate meticulous surgical technique and planning

Outcomes following different types of surgical intervention for femoroacetabular impingement (FAI) are well reported individually but comparative data are deficient. The purpose of this study was to conduct a systematic review (SR) and meta-analysis to analyze the outcomes following surgical management of FAI by hip arthroscopy (HA), anterior mini open approach (AMO), and surgical hip dislocation (SHD). This SR was registered with PROSPERO. An electronic database search of PubMed, Medline, and EMBASE for English and German language articles over the last 20 years was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We specifically analyzed and compared changes in patient-reported outcome measures (PROMs), α-angle, rate of complications, rate of revision, and conversion to total hip arthroplasty (THA). A total of 48 articles were included for final analysis with a total of 4,384 hips in 4,094 patients. All subgroups showed a significant correction in mean α angle postoperatively with a mean change of 28.8° (95% confidence interval (CI) 21 to 36.5; p < 0.01) after AMO, 21.1° (95% CI 15.1 to 27; p < 0.01) after SHD, and 20.5° (95% CI 16.1 to 24.8; p < 0.01) after HA. The AMO group showed a significantly higher increase in PROMs (3.7; 95% CI 3.2 to 4.2; p < 0.01) versus arthroscopy (2.5; 95% CI 2.3 to 2.8; p < 0.01) and SHD (2.4; 95% CI 1.5 to 3.3; p < 0.01). However, the rate of complications following AMO was significantly higher than HA and SHD. All three surgical approaches offered significant improvements in PROMs and radiological correction of cam deformities. All three groups showed similar rates of revision procedures but SHD had the highest rate of conversion to a THA. Revision rates were similar for all three revision procedures

Revision total hip arthroplasty (rTHA) in the presence of femoral defects can be technically challenging. Reconstruction with long stems is widely accepted as the standard. However long stems can be difficult to insert and can compromise distal bone stock for future revisions. The aims of this study were to identify whether there was a difference in survival and outcomes following rTHA using a long versus standard or short femoral stem. A comprehensive systematic review was performed according to PRISMA guidelines using the MEDLINE, EMBASE, Chochrane Library and Web of Science databases. Inclusion criteria were (i) adult patients >18 years; (ii) randomised controlled trials, joint registry, or cohort studies; (iii) single or staged rTHA for Paprosky 1–3B femoral defects. Exclusion criteria were (i) mixed reporting without subgroup analysis for revision stem length; (ii) ex-vivo studies. Screening for eligibility and assessment of studies was performed by the authors. Out of 341 records, 9 studies met criteria for analysis (including 1 study utilising joint registry data and 1 randomised controlled trial). Across studies there were 3102 rTHAs performed in 2982 patients with a mean age of 67.4 years and a male: female ratio of 0.93. Revision prostheses were long-stemmed in 1727 cases and short or standard in 1375 cases with a mean follow up of 5 years (range, 0-15 years). On subgroup analysis the use of a long cemented stem compared to a long cementless prosthesis was associated with fewer complications and periprosthetic fracture in older patients. Survivorship was 95% with short stems compared to 84% with long stems at 5 years. Moderate quality evidence suggests that in rTHA with Paprosky type 1-3B femoral defects, the use of a short or standard stem can achieve comparable outcomes to long stems with fewer significant complications and revisions. Using a shorter stem may yield a more straightforward surgical technique and can preserve distal bone stock for future revision

Introduction. The number of total hip arthroplasties (THAs) performed per year is increasing for reasons that are not fully explained by a growing and aging population. The purpose of this study was to determine the role of patient health status as an indication for surgery and determine if patients are undergoing surgery at a better health status than in the past. Methods. To examine how pre-operative functional health status has changed over time, a systematic review and meta-analysis of the Medline, Embase, and Cochrane databases was performed in accordance with the PRISMA guidelines. Health status was assessed using the physical component summary (PCS) score from the 36-item short-form (SF-36) health survey. Only primary procedures were included; revisions were excluded. Articles were screened by two independent reviewers with conflicts resolved by consensus with a third reviewer. Meta-regression analysis was performed to determine the effect of time, patient age, and gender. Subgroup analysis was performed to assess differences between countries. Results. A total of 1,504 articles were identified. Data from 172 independent groups representing 18,644 patients recruited from 1990–2013 and identified from 107 articles were included in the final analysis. The mean pre-op PCS score was 31.2 (95% Confidence Interval: 30.5–31.9) with a 95% prediction interval of 22.6–39.8. The variance across studies was found to be statistically significant (p = 0.000) with 97.25% of this variance due to true variance. Neither year of enrolment, mean age, nor the percentage of females per group were found to have any significant effect. There were no significant differences between countries. Conclusion. Patients are undergoing THA at a similar health status to the past. Patient age and gender do not influence the functional status at which patients are indicated for surgery. There are no significant regional differences in pre-op health status

Aims. Urinary catheter use in the peri-operative and post-operative phase following arthroplasty may be associated with increased risk of urinary tract infection (UTI) and deep prosthetic joint infection (PJI). These can be catastrophic complications in joint arthroplasty. We performed a systematic review of the evidence on routine use of antibiotics for urinary catheter insertion and removal following arthroplasty. Methods. Electronic databases were searched using the HDAS interface. Grey literature was also searched. From 219 citations, six studies were deemed eligible for review. Due to study heterogeneity a narrative approach was adopted. Methodological quality of each study was assessed using the CASP appraisal tool. Included studies were found to have moderate to good methodological quality. Results. A total of 4696 hip and knee arthroplasties were performed on 4578 participants across all studies. Of these 1475 (31%) were undertaken on men and 3189 (68%) on women. The mean age of the study participants was 69 years. 3489 cases (74.3%) related to hip arthroplasty and 629 of cases (13.4%) to knee arthroplasty. 578 cases (12.3%) specified either hip or knee arthroplasty. In total, 45 PJIs were reported across all studies (0.96%). Two of the studies found either no PJI or no statistical difference in the rate of PJI when antibiotic prophylaxis was not used for catheter manipulation. Where studies report potential haematogenous spread from UTIs, this association can only be assumed. Rates of bacteriuria varied greatly between studies and depend on timing of sample and gender. Increased duration of urinary catheterisation is positively associated with UTI. Conclusion. It remains difficult to justify the routine use of prophylactic antibiotics for catheter manipulation in well patients undergoing arthroplasty. Their use is not recommended for this indication

Introduction. Two-stage reimplantation for prosthetic joint infection (PJI) of the hip is the standard of care with a 5–10% recurrence at a minimum two-year follow-up. Compiling outcomes data for this standard of care is necessary in order to characterize long-term reinfection risk and the culpable microbiology. The purpose of this study was to determine the long-term success of two-stage reimplantation and identify the factors that affected the success. Methods. We performed a systematic review of randomized control trials, cohort studies, and case series through May 2019, searching Embase, Medline via PubMed, and Cochrane Library for the concept of two-stage reimplantation for the treatment of hip and knee PJIs, yielding 464 unique citations for abstract review, of which 135 were reviewed in full. Our parameters of interest included: reinfection and mortality events following successful reimplantation, the timing of these events, and the microbiology of index and recurrent infections. Results. Meeting our criteria were 59 studies with 4,494 patients (1,842 hips) who had completed reimplantation. Among successfully reimplanted hips, 4.76% (95% CI, 2.00–8.41) were reinfected by 24 months, 6.84% (4.92–9.02) were reinfected by final follow-up, 1.6% (0.32–3.52) were reinfected with an identical organism(s) with identical resistance, and 2.55% (0.77–5.03) were reinfected with a novel organism(s) or novel resistance. In 24 studies with reinfected patients and sufficient data, 8 studies reported an average interval from reimplantation to reinfection greater than 24 months, and 14 reported at least 1 patient with a reinfection event greater than 48 months following reimplantation. Conclusion. The results from this review determined that the host of an index PJI faces ongoing risk of recurrent infection years into the post-operative period despite initial eradication and that novel microbiology is the cause of a significant proportion of failures.

Aims. The aim of this study was to conduct evidence synthesis on the available published literature of the impact of the training status of the operating surgeon (trainee vs. consultant) on the survival and revision rate of primary hip and knee replacements. Patients and Methods. We conducted a systematic review according to Cochrane guidelines. Separate searches were performed for hip and knee replacements, with meta-analysis and presentation of results in parallel. We searched MEDLINE and Embase databases from inception to 17 September 2019 and included controlled trials and cohort studies reporting implant survival estimates, or revision rates of hip and knee replacements according to the grade of the operating surgeon. This study was registered with PROSPERO (CRD42019150494). Results. 8 studies (5 hip papers and 3 knee papers) met the inclusion criteria. There was no significant difference in the survival estimates for total hip replacements (THRs) performed by trainees compared to consultants at 5-years follow-up (97.9% vs 98.1%, p = 0.74). Furthermore, there was no significant difference in the revision rate of THRs performed by trainees and consultants at both 5 and 10-year intervals of follow-up (relative risk [RR]: 5yrs = 0.88 (95% CI: 0.46, 1.70; P = 0.71); 10yrs = 0.68 (95% CI: 0.37, 1.26; P = 0.22)). There was no significant difference in the survival estimates at 10-years for total knee replacements (TKRs) performed by trainees compared to consultants (96.2% vs 95.1%, p=0.49). Conclusion. There is no evidence in the existing literature that trainee surgeons have worse outcomes than their consultant colleagues, in terms of the survival, or rate of revision of hip and knee replacements at 5–10 years follow-up. This may mean that there is genuinely no difference or that, in the context of contemporary training programmes, appropriate case-mix selection and supervision of trainees is currently employed

We report a systematic review and meta-analysis of published randomised controlled trials evaluating the efficacy of tranexamic acid (TXA) in reducing blood loss and transfusion in total hip replacement (THR). The data were evaluated using the generic evaluation tool designed by the Cochrane Bone, Joint and Muscle Trauma Group. We identified 11 clinical trials which were suitable for detailed extraction of data. There were no trials that used TXA in revision THR. A total of seven studies (comprising 350 patients) were eligible for the blood loss outcome data. The use of TXA reduced intra-operative blood loss by a mean of 104 ml (95% confidence interval (CI) −164 to −44, p = 0.0006, heterogeneity I. 2. 0%), postoperative blood loss by a mean of 172 ml (95% CI −263 to −81, p = 0.0002, heterogeneity I. 2. 63%) and total blood loss by a mean of 289 ml (95% CI −440 to −138, p < 0.0002, heterogeneity I. 2. 54%). TXA led to a significant reduction in the proportion of patients requiring allogeneic blood transfusion (risk difference −0.20, 95% CI −0.29 to −0.11, p < 0.00001, I. 2. 15%). There were no significant differences in deep-vein thrombosis, pulmonary embolism, infection rates or other complications among the study groups

Extracapsular Hip Fractures (EHF's) are a significant health burden on healthcare services. Optimal treatment is controversial with conflicting evidence being reported. Currently treatment is undertaken with Intramedullary Nail (IMN) or Dynamic Hip Screw (DHS) constructs with a recent increase in IMN use (1). This study aims to conduct a systematic review of Randomised Control Trials published between 2020 and 2023 with particular focus on patient demographics and holistic patient outcomes. Using a unified search-protocol, RCT's published between 2020 and 2023 were collected from CENTRAL, PubMed, MEDLINE and EMBASE. Rayyan software screened duplicates. Using the CASP and Cochrane Risk of Bias Tool papers were critically examined twice, and Blood Loss, Infection and Mobility described the patient journey. Patient demographics were recorded and were contrasted with geographically diverse cohort studies to compare population differences. Parametric tests were used to determine significance levels between population demographics, namely Age and Sex. Eleven papers were included, representing 908 patients (436 Male). The mean age for patients was 64.39. There was considerable risk of bias in 7/11 studies owing to the randomization process and the recording of data. Four Cohort studies were selected for comparison representing 14314 patients. Mean age was significantly different between Cohort Studies and RCT's (Independent T-Test, df 13, t=7.8, p = <0.001, mean difference = 19.251, 95% CI = 13.888, 24.613). This was also true for sex ratios included in the studies (df 13, t = -2.268, p = 0.024, Mean Difference = -0.4884, 95% CI = -0.9702, -0.0066). To conclude, RCT's published in the post COVID-19 era are not representative of patient demographics. This has the potential to provide inaccurate information for implant selection. Additionally further research must be conducted in how to better improve RCT patient inclusion so as to be more representative of patients whilst balancing the risks of operations

Introduction. The mortality and serious side effects risk of both medical and surgical management of hip and knee osteoarthritis (OA) has been widely published. To date however, there are no studies comparing safety between the two treatment modalities. We aimed to systematically review the published evidence on the mortality and serious complications risk of the various treatments for hip and knee OA. Methods. We searched for studies investigating the safety of arthroplasty, arthroscopy, opioids, non-steroidal anti-inflammatory drugs (NSAIDS), and paracetamol using PubMed, Score, Cochrane, PEDRO, and Google Scholar. The phrase “osteoarthritis treatment” was searched and then combined using Boolean connectors (“OR and “AND) with “serious complications” or “serious adverse events” or “mortality”. The quality of included studies was assessed based on the approach used by the AAOS in judging the quality of treatment studies. Results. 19 studies were included in the review. Mortality risk was highest for Naproxen HR = 3 (1.9; 4.6) and lowest for total hip replacement RR = 0.7 (0.7; 0.7). Highest serious gastrointestinal complication risk was reported for diclofenac OR = 4.77 (3.94; 5.76) and lowest for total knee replacement HR = 0.6 (0.49; 0.75). Ibuprofen had the highest renal complications risk OR=2.32 (1.45; 3.71) whereas celecoxib had the lowest RR = 0.61 (0.4; 0.94). Celecoxib users had the highest cardiovascular (CV) complication risk OR=2.26 (1; 5.1) and the lowest was for tramadol RR = 1.1 (0.87; 1.4). Discussion. Long term medical management of hip and knee OA particularly with NSAIDS may carry a higher mortality risk compared to surgery. Conclusion. The practitioner and patient should carefully consider the risks of medications as well as surgery prior to commencing treatment. Treatment choice should also be tailored to the patient taking into account known GI, CVS, and renal co-morbidities

Background. Elite performance has tremendous physical demands and places elite athletes at an increased risk of sustaining a variety of orthopaedic injuries (1–4). Pain around the hip is common in high-level athletes representing up to 6% of all athletic injuries (5–7). Expedient diagnosis and effective treatment are paramount for their future sporting careers and to prevent subsequent joint degeneration. The purpose of this systematic review was to evaluate the outcome and the rate of return to play (RTP) following hip arthroscopy in elite athletes. Methods. A computer-based systematic search followed the PRISMA Guidelines (8) was performed using the 6 most comprehensive databases (CENTRAL, PUBMED, EMBASE, SCOPUS, EBSCO, Google Scholar and Web of Science) and included all published studies from inception until November 1. st. 2018. Weighted means were calculated for the rate of RTP and duration and for patient reported outcome measures (PROMs). Results. After eligibility screening, 17 articles were included with a total of 736 male and seven female patients, 761 hips and a mean age of 27.9±3.6 years. The mean follow-up period was 35.8±13.4 months and 17.1±12.3% of athletes had undergone bilateral hip arthroscopies. Overall, 93.9% (95% CI: 90.5, 96.6, P < 0.0001) of patients demonstrated return to sport after 6.7±2.5 months post-surgery and all PROMs improved post-operatively. During follow-up, 9.6% (95% CI: 5.2, 15.2, P = 0.025) patients needed further intervention. Conclusion. A high percentage of elite athletes return to the same level of competition after hip arthroscopy, with a low rate of further interventions. Hip arthroscopy appears to be an efficacious treatment for elite athletes suffering for hip and/or groin pain

Introduction. Previous systematic reviews have shown that patients experience low physical activity levels following total hip replacement (THR). However no previous systematic reviews have examined the changes between pre- and post-operative physical activity levels. Methods. AMED, MEDLINE, EMBASE, CENTRAL, CINHAL, openSIGLE, . ClinicalTrials.gov. and UK Clinical Trials Gateway databases were searched to 19. th. May 2015. All study designs presenting data on physical activity at pre- and up to one-year post-operatively were included. Eligible studies were critically appraised using the Cochrane risk of bias tool (for randomised controlled trials (RCTs)) and the CASP tool (non-RCTs). Where possible, mean differences (MD) and 95% confidence intervals (CI) were calculated through meta-analyses. Results. From 3850 citations, 16 met the eligibility criteria; nine included in the meta-analysis. The quality of the evidence was graded low to moderate. There was no statistically significant difference in physical activity pre- to one year post-THR when assessed using: movement-related activity (MD: −0.08; 95% CI:- 1.60 to 1.44; I. 2. =0%; n=77), percentage of 24 hours spent walking (MD: −0.21; 95% CI: −1.36 to 0.93; I. 2. =12%; n=65), six minute walk test (MD: −60.85; 95% CI: −122.41 to 0.72; I. 2. =84%; n=113) or the cardiopulmonary exercise test (MD: −0.24; 95% CI: −1.36 to 0.87; I. 2. =0%; n=76). Discussion. There is no evidence to suggest that physical activity changes pre- compared to post-THR. The low methodological quality of the included papers means this finding should be viewed with caution. Further research is warranted to better understand the relationship between physical activity pre- and post-THR, as greater consideration may be needed to increase physical activity in this population post-operatively. Conclusion. Surprisingly, there is no significant change in physical activity following THR. Surgeons, physiotherapists and patients should consider how to increase and maintain physical activity levels to maximise the potential for wider-health benefits following THR

Arthroplasty in patients who are intravenous drug abusers presents a complex challenge, frequently requiring intervention at a younger age. The cohort suffer increased complication rates due to significant co-morbidities and poor engagement in medical services, in comparison to other patients undergoing lower limb arthroplasty. Multiple small studies show arthroplasty in this patient cohort is associated with high complication and mortality rates.

A search of electronic databases were undertaken with the assistance of the library services from the Rotherham NHS Foundation Trust, including Chocraine, SCOPUS and PubMed.

Abstracts were reviewed and relevant studies extracted for full review. Full text articles were reviewed based on strict inclusion and exclusion criteria.

Searches identified Two thousand and forty-four papers; twenty-seven studies were identified for full review of the paper based on the inclusion criteria above. From this, nine studies were deemed appropriate to for data extraction.

These nine papers present one hundred and thirty-two cases of lower limb arthroplasty, fifty nine Total Knee Arthroplasty and seventy three Total Hip Arthroplasty. From this the authors examined incidences of implant failure due to infection, revision, mortality, dislocation, aseptic loosening, peri-prosthetic fracture, or other causes. Of these, 58% of patients (n = 77) with a history of intravenous drug abuse suffered some form of significant complication; 4% of this cohort (n = 5) were lost to follow up. Infection was reported in 32% of cases and a mortality rate of 4.7%.

The rising demand of lower limb arthroplasty for intra-venous drug abusers presents a very real problem for the modern Orthopaedic surgeon. Within the studies examined, more than half report implant failure. This study synthesises the available literature regarding treatment of these patients to help facilitate decision making and informed consent.

Industries such as agriculture, construction and military have stringent rules about hearing protection due to the risk of noise induced hearing loss (NIHL). Due to the use of power tools, orthopaedic staff may be at risk of the same condition. The UK Health and Safety Executive (HSE) have clear standards as to what is deemed acceptable occupational noise levels on an A-weighted and C weighted scale. This review is aimed to assess evidence on noise exposure testing within Orthopaedic theatres to see if it exceeds the HSE regulations.

A targeted search of online databases PUBMED and EMBASE was conducted using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) principles. This review was registered prospectively in PROSPERO. An eligibility criterion identifying clinical studies which assessed noise exposure for Orthopaedic staff in theatres were included. Noise exposure data was extracted from these studies and a comparison was made with A weighted and C weighted acceptable exposure levels as quoted in the HSE regulations.

Fourteen papers were deemed eligible, which reviewed 133 Orthopaedic operations and 64 Orthopaedic instruments. In total, 61% (81 of 132) of Orthopaedic operations and 70% (45 of 64) of instruments exceeded the noise regulations on an A weighted scale. 22% (10 of 46) of operations exceeded the maximum C weighted peak acceptable noise level.

Orthopaedic instruments and operations can exceed safe occupational noise levels. NHS Trusts have clear policies about noise exposure in the workplace but have yet to identify Orthopaedic theatres as a potential at risk area. Orthopaedic staff need education, monitoring and protection whereas Employers and Occupational Health should consider assessments to identify at risk staff in Orthopaedic theatres and offer preventative methods from NIHL.

The aim of this study was to systemically review the evidence for the use of intra-operative cell salvage (ICS) among patients undergoing revision hip arthroplasty, and synthesis the available data to quantify any associated reduction in allogeneic blood transfusion.

An electronic database search of MEDLINE (PubMed), EMBASE, Scopus and the Cochrane Library was completed from the date of inception to 9^th February 2021, using a search strategy and protocol created in conjunction with the PRISMA statement. Inclusion criteria were (i) adult patients >18 years, (ii) ICS utilised in one study group, (iii) revision hip arthroplasty performed. Exclusion criteria were (i) pre-donation of red blood cells, (ii) mixed reporting without dedicated subgroup analysis for revision hip arthroplasty. Screening for eligibility, and quality assessment of included studies, was performed independently by two authors (TW and DH), and any disputes settled by third author (AK).

Of the 187 records identified, 11 studies were included in the qualitative analysis, and 5 studies suitable for quantitative meta-analysis. Across the included studies there were 1856 participants, with a mean age of 63.86 years and a male: female ratio of 0.90. Quality assessment demonstrated low or medium risk of bias only. For revision hip arthroplasty patients receiving ICS, 37.07% required ABT with a mean transfusion of 1.92 units or 385ml per patient. For patients treated without ICS, 64.58% required ABT with a mean transfusion of 4.02 units or 803ml per patient. This difference achieved statistical significance (p < 0.05).

This study has demonstrated a significant reduction in the need for allogenic blood transfusion associated with intra-operative cell salvage use among patients undergoing revision hip arthroplasty. This study therefore supports the routine use of ICS in this patient group. However, a major limitation is the lack of clinical outcomes reported by the available studies. Further research is required to determine whether this effect is associated with sub-groups of revision arthroplasty procedure, and whether ICS impacts clinical outcomes such as length of stay, rehabilitation progress and mortality.
