Aims Dislocation is the most common indication for further surgery following total hip arthroplasty (THA) when undertaken in patients with a femoral neck fracture. This study aimed to assess the complication rates of THA with dual mobility components (THA-DMC) following a femoral neck fracture and to compare outcomes between THA-DMC, conventional THA, and hemiarthroplasty (HA). Methods We performed a systematic review of all English language articles on THA-DMC published between 2010 and 2019 in the MEDLINE, EMBASE, and Cochrane databases. After the application of rigorous inclusion and exclusion criteria, 23 studies dealing with patients who underwent treatment for a femoral neck fracture using THA-DMC were analyzed for the rate of dislocation. Secondary outcomes included reoperation, periprosthetic fracture, infection, mortality, and functional outcome. The review included 7,189 patients with a mean age of 77.8 years (66.4 to 87.6) and a mean follow-up of 30.9 months (9.0 to 68.0). Results THA-DMC was associated with a significantly lower dislocation rate compared with both THA (OR 0.26; 95% CI 0.08 to 0.79) and HA (odds ratio (OR) 0.27; 95% confidence interval (CI) 0.15 to 0.50). The rate of large articulations and of intraprosthetic dislocation was 1.5% (n = 105) and 0.04% (n = 3) respectively. Conclusion THA-DMC when used in patients with a femoral neck fracture is associated with a lower dislocation rate compared with conventional arthroplasty options. There was no increase in the rates of other complication when THA-DMC was used. Future cost analysis and prospective, comparative studies are required to assess the potential benefit of using THA-DMC in these patients. Cite this article: Bone Joint J 2020;102-B(7):811–821.
Background: The Integra Cadence total ankle replacement (TAR) is a fourth-generation anatomic, fixed-bearing implant requiring minimal tibial and talar resection, which has been in clinical use since June 2016. The primary purpose of this study is to assess its short-term clinical and radiographic outcomes after TAR using this prosthesis. Methods: This is a prospective case series of consecutive patients that underwent TAR using this novel fourth-generation prosthesis between June 2016 and November 2017. The primary outcome of interest was the Ankle Osteoarthritis Scale (AOS). Secondary outcomes included Short Form Health Survey–36 (SF-36) scores, radiographic alignment, complications, reoperations, and revisions. Results: In total, 69 patients were included in our study. Fifty-one patients (73.9%) required a total of 91 ancillary procedures. Postoperatively, AOS pain scores decreased significantly by an average of 17.8±30.1 points from 45.9±18.2 to 28.4±27.3 ( P < .001). AOS disability scores also decreased significantly following surgery by an average of 22.0±30.5 points from 53.9±18.5 to 32.5±27.9 ( P < .001). The SF-36 physical component summary score improved 10.4±9.8 points from 33.1±9.1 to 42.6±9.1 ( P < .001). Radiographic analysis demonstrated significant improvement to neutral coronal plane alignment, which was achieved in 97% of patients ( P < .01) with no cyst formation at 2 years. There was 1 reported complication, 9 reoperations, and no metal or polyethylene component revisions. Overall, the 2-year implant survivorship was 100% in our cohort. Eighteen patients (26.1%) demonstrated fibrous ingrowth of the tibial component. However, outcome scores for these patients did not demonstrate any negative effects. Conclusions: In our hands, this TAR system demonstrated excellent early clinical and radiographic outcomes. Patients reported improved physical health status, pain, and disability in the postoperative period. Total ankle instrumentation allowed for accurate and reproducible implantation with correction of coronal and sagittal plane deformities. Early results for the clinical use of this TAR system are promising, but further long-term prospective outcome studies are necessary. Level of Evidence: Level IV, case series.
Background:It is estimated that one-quarter to half of all hospital waste is produced in the operating room. Recycling of surgical waste in the perioperative setting is uncommon, even though there are many recyclable materials. The objective of this study was to determine the amount of waste produced in the preoperative and operative periods for several orthopedic subspecialties and to assess how much of this waste was recycled.Methods: Surgical cases at 1 adult and 1 pediatric tertiary care hospital in Calgary, Alberta, were prospectively chosen from 6 orthopedic subspecialties over a 1-month period. Waste was collected, weighed and divided into recyclable and nonrecyclable categories in the preoperative period and into recyclable, nonrecyclable, linen and biological categories in the intraoperative period. Waste bags were weighed using a portable hand-held scale. The primary outcome was the amount of recyclable waste produced per case. Secondary outcomes included the amount of nonrecyclable, biological and total waste produced. An analysis of variance was performed to test for statistically significant differences among subspecialties.Results: This study included 55 procedures. A total of 341.0 kg of waste was collected, with a mean mass of 6.2 kg per case. Arthroplasty produced a greater amount of recyclable waste per case in the preoperative (2017.1 g) and intraoperative (938.6 g) periods as well as total recyclable waste per case, resulting in a greater ratio of waste recycling per case then nearly all other subspecialties in the preoperative (86%) and intraoperative (14%) periods. Arthroplasty similarly produced a greater amount of nonrecyclable waste per case (5823.6 g) than the other subspecialties, most of which was produced during the intraoperative period (5512.9 g). Overall an average of 27% of waste was recycled per case. Conclusion:Among orthopedic subspecialties, arthroplasty is one of the largest waste producers and it has the highest potential for recycling of materials. Effective recycling programs in the operating room can reduce our ecological footprint by diverting waste from landfills, as our study revealed that nearly three-quarters of this waste is recyclable.Résultats : Au total, 55 opérations ont été étudiées, et 341,0 kg de déchets ont été recueillis, pour une moyenne de 6,2 kg par cas.

Cubital tunnel syndrome (CuTS) is one of the most common compression neuropathies of the upper extremity. Conservative management of cubital tunnel syndrome is often considered first line therapy for mild or moderate symptoms; however, there is little evidence-based literature to guide physicians in this regard. As such, the objective of this study is to complete a comprehensive literature search of the conservative therapies available for treatment of CuTS. Additionally, we hope to assess the evidence for each therapy so that we can make evidence-based recommendations regarding the type and duration of optimal treatment. The databases MEDLINE, EMBASE, and CINAHL were search using a sensitive search strategy. Eligibility for studies included any studies or conference abstracts in which patients were treated conservatively for primary CuTS. Any form of non-operative treatment was acceptable. A data extraction form was developed to collect all information and outcomes of interest, including study design, level of evidence, number of patients, treatment modalities, follow-up time, patient reported outcomes, and electrophysiological markers. Qualitative and quantitative analysis was then completed based on the data extraction form. Given the heterogeneity of the included studies, results were summarized as best evidence available. Our sensitive literature search produced 6484 studies. Initial screening based on title and abstract resulted in the selection of 40 studies that underwent full text review. From these 19 studies were included for analysis in our systematic review. There were 3 level I studies, 4 level II studies, 3 level III studies, and 9 level IV studies. In total this included 844 patients. The most commonly reported outcomes included subjective patient reported outcomes and nerve conduction studies. The most common treatment modalities, from most to least common, included education and activity modification, splinting, steroid/lidocaine injection, nerve mobilization/gliding, pulsed ultrasound, laser therapy, non-steroidal anti-inflammatory drugs, and physiotherapy. The most common duration of therapy was 3 months with a median follow-up time of 3 months. There was moderate strength evidence to recommend the use of education/activity modification or splinting in mild or moderate CuTS. There is a paucity of literature and high-quality studies regarding the conservative management of CuTS. Regardless, there appears to be a role for non-operative management in CuTS, although further studies are needed to delineate this role further. In the cases of mild or moderate CuTS it is reasonable to trial education/activity modification or splinting as both appear to be equally effective.
Objective: Previous systematic reviews looking at timing of anterior cruciate ligament reconstruction (ACLR) examined the functional outcomes and range of motion; however, few have quantified the effect of timing of surgery on secondary pathology. The goal of this study was to analyze the effects of early ACLRs versus delayed ACLR on the incidence of meniscal and chondral lesions. Data Sources: We searched MEDLINE, EMBASE, and CINAHL on March 20, 2018, for randomized control trials (RCTs) that compared early and delayed ACLR in a skeletally mature population. Two reviewers independently identified trials, extracted trial-level data, performed risk-of-bias assessments using the Cochrane Risk of Bias tool, and evaluated the study methodology using the Detsky scale. A meta-analysis was performed using a random-effects model with the primary outcome being the total number of meniscal and chondral lesions per group. Results: Of 1887 citations identified from electronic and hand searches, we included 4 unique RCTs (303 patients). We considered early reconstruction as <3 weeks and delayed reconstruction as >4 weeks after injury. There was no evidence of a difference between early and late ACLR regarding the incidence of meniscal [relative risk (RR), 0.98; 95% confidence interval (CI), 0.74-1.29] or chondral lesions (RR, 0.88; 95% CI, 0.59-1.29), postoperative infection, graft rupture, functional outcomes, or range of motion. Conclusions: We found no evidence of benefit of early ACLR. Further studies may consider delaying surgery even further (eg, >3 months) to determine whether there are any real benefits to earlier reconstruction.
Introduction: The purpose of this study is to evaluate the role of major psychiatric illness on patient outcomes after total joint arthroplasty. Methods: Patients with a diagnosis of a major psychiatric disorder undergoing total joint arthroplasty were retrospectively matched one-to-one with a cohort without such a diagnosis. Major psychiatric disorder in the registry was identified by diagnosis of anxiety, mood, or a psychotic disorder. Primary outcome of interest included perioperative Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Secondary outcomes included EuroQol-5D, adverse events, length of stay, 30-day readmission, and discharge destination. Results: Total number of patients were 1828. The total hip arthroplasty (37.80 ± 17.91, p = 0.023) and the total knee arthroplasty psychiatric group (43.38 ± 18.41, p = 0.050) had significantly lower pre-operative WOMAC scores. At 3 months, the total hip arthroplasty (76.74 ± 16.94, p = 0.036) and total knee arthroplasty psychiatric group (71.09 ± 18.64, p < 0.01) again had significantly lower 3-month post-operative WOMAC score compared to the control groups. However, outcomes at 1 year were difficult to interpret, as patients with major psychiatric conditions had an extremely high loss to follow-up. Compared to the control groups, the total hip arthroplasty and total knee arthroplasty psychiatric group had an increased length of stay by 1.43 days (p < 0.01) and 0.77 days, respectively (p = 0.05). Similarly, the psychiatric groups were discharged directly home less often (total hip arthroplasty 86.9%, p = 0.024 and total knee arthroplasty 87.6%, p = 0.022) than the control groups. Conclusion: Patients with the diagnosis of a major psychiatric illness have an increased length of stay and are more likely to require a rehabilitation facility, compared to the control groups. Arguably, of utmost importance, there is a very high rate of loss to follow-up within the psychiatric groups. As such, we recommend these patients should be treated for their diagnosis prior to total joint arthroplasty. Furthermore, importance of clinical follow-up should be emphasized carefully.
