One Hundred Twenty-Day Mortality Rates for Hip Fracture Patients with COVID-19 Infection
Clin Orthop Surg. 2021 Jun;13(2):135-143. doi: 10.4055/cios20286. Epub 2021 May 18.ABSTRACTBACKGROUND: Increased 30-day mortality rates have been reported for patients with hip fractures and a concurrent diagnosis of coronavirus disease 19 (COVID-19) infection. Due to nosocomial spread of infection and the variable incubation period with the virus, follow-up past 30 days after injury is required to evaluate the true mortality amongst these patients. We aim to assess 120-day mortality rates in hip fracture patients with COVID-19 infection and compare this to hip fracture patients without COVID-19 infection presenting during...

Treatment of Recurrent Hemarthrosis Following Total Knee Arthroplasty Using Surgical Interventions
CONCLUSIONS: Interventional angiography was used to aid in the diagnosis of recurrent hemarthrosis, and therapeutic selective embolization provided satisfactory clinical results. Even if selective embolization fails, interventional angiography may be helpful for further surgical procedures because it reveals vascular blush of a bleeding site. Therefore, interventional angiography and selective embolization should be considered to be a useful treatment for recurrent hemarthrosis after TKA.PMID:34094005 | PMC:PMC8173232 | DOI:10.4055/cios20066 (Source: Clinics in Orthopedic Surgery)

Perioperative Outcomes of Patients Who Were Not Candidates for Additional Nonsteroidal Anti-inflammatory Drugs in a Multimodal Pain Control Regimen for Total Knee Arthroplasty
CONCLUSIONS: Patients who were not candidates for NSAIDs had significantly higher pain scores and consumed more morphine after TKA. They also tended to have greater blood loss and the rising of cardiac biomarkers during the first 48 hours after TKA. Hence, these patients may benefit from supplementary analgesia and appropriate perioperative monitoring.PMID:34094006 | PMC:PMC8173236 | DOI:10.4055/cios20154 (Source: Clinics in Orthopedic Surgery)

We surmise that the ATEHL acts as an antagonist with the EHB when the toe is extending, which might help prevent the occurrence of hallux valgus deformity.PMID:34094018 | PMC:PMC8173238 | DOI:10.4055/cios20054 (Source: Clinics in Orthopedic Surgery)

Corticosteroid Injection for Morton's Interdigital Neuroma: A Systematic Review
CONCLUSIONS: Corticosteroid injections showed a satisfactory clinical outcome in patients with Morton's interdigital neuroma although almost 30% of the included subjects eventually underwent operative treatment. Our recommendation for future research includes using more objective outcome parameters, such as foot and ankle outcome scores or foot and ankle ability measures. Moreover, studies on the safety and effectiveness of multiple injections at the same site are highly necessary.PMID:34094019 | PMC:PMC8173242 | DOI:10.4055/cios20256 (Source: Clinics in Orthopedic Surgery)

Overview and Spinal Implications of Leg Length Discrepancy: Narrative Review
Clin Orthop Surg. 2021 Jun;13(2):127-134. doi: 10.4055/cios20224. Epub 2021 May 18.ABSTRACTLeg length discrepancy (LLD) is an underrecognized and prevalent condition among the U.S. population, with effects varying depending on the cause and size of the discrepancy. LLD occurs when the paired lower extremities are unequal in length and can be etiologically classified as functional or structural. Length differences are typically less than 10 mm and asymptomatic or easily compensated for by the patient through self-lengthening or shortening of the lower extremities. Literature review of the etiology, diagnostic modalities, cl...

One Hundred Twenty-Day Mortality Rates for Hip Fracture Patients with COVID-19 Infection
Clin Orthop Surg. 2021 Jun;13(2):135-143. doi: 10.4055/cios20286. Epub 2021 May 18.ABSTRACTBACKGROUND: Increased 30-day mortality rates have been reported for patients with hip fractures and a concurrent diagnosis of coronavirus disease 19 (COVID-19) infection. Due to nosocomial spread of infection and the variable incubation period with the virus, follow-up past 30 days after injury is required to evaluate the true mortality amongst these patients. We aim to assess 120-day mortality rates in hip fracture patients with COVID-19 infection and compare this to hip fracture patients without COVID-19 infection presenting during...

Comparison of Cup Setting Angle Accuracy between Computed Tomography-Based and Computed Tomography-Free Navigation in the Same Patients with Crowe's Classification I or II Hip Dysplasia
Clin Orthop Surg. 2021 Jun;13(2):144-151. doi: 10.4055/cios20145. Epub 2021 Apr 12.ABSTRACTBACKGROUD: In total hip arthroplasty, the cup setting angle may affect the postoperative results. In recent years, both computed tomography-based navigation and computed tomography-free (imageless) navigation have been reported to produce high accuracy in cup installation; however, no direct comparison between these two methods has been performed. The present study aimed to directly compare the cup installation angle accuracy between computed tomography-based navigation and computed tomography-free navigation in patients with Crowe's...

Treatment of Recurrent Hemarthrosis Following Total Knee Arthroplasty Using Surgical Interventions
CONCLUSIONS: Interventional angiography was used to aid in the diagnosis of recurrent hemarthrosis, and therapeutic selective embolization provided satisfactory clinical results. Even if selective embolization fails, interventional angiography may be helpful for further surgical procedures because it reveals vascular blush of a bleeding site. Therefore, interventional angiography and selective embolization should be considered to be a useful treatment for recurrent hemarthrosis after TKA.PMID:34094005 | PMC:PMC8173232 | DOI:10.4055/cios20066 (Source: Clinics in Orthopedic Surgery)

Perioperative Outcomes of Patients Who Were Not Candidates for Additional Nonsteroidal Anti-inflammatory Drugs in a Multimodal Pain Control Regimen for Total Knee Arthroplasty
CONCLUSIONS: Patients who were not candidates for NSAIDs had significantly higher pain scores and consumed more morphine after TKA. They also tended to have greater blood loss and the rising of cardiac biomarkers during the first 48 hours after TKA. Hence, these patients may benefit from supplementary analgesia and appropriate perioperative monitoring.PMID:34094006 | PMC:PMC8173236 | DOI:10.4055/cios20154 (Source: Clinics in Orthopedic Surgery)

Comparison of Patellofemoral-Specific Clinical and Radiographic Results after Total Knee Arthroplasty Using a Patellofemoral Design-Modified Prosthesis and Its Predecessor
Clin Orthop Surg. 2021 Jun;13(2):175-184. doi: 10.4055/cios20188. Epub 2021 Feb 2.ABSTRACTBACKGROUD: One recently developed total knee arthroplasty (TKA) prosthesis was designed to alter the patellofemoral geometry and optimize patellar tracking compared to its predecessor. Despite an expectation that the improved design would contribute to optimal patellofemoral compatibility, its effect has not been confirmed with patellofemoral-specific clinical scoring systems and radiographic parameters. Our purpose was to compare patellofemoral-specific clinical and radiographic results after TKA using a patellofemoral design-modifie...

Truncal Changes in Patients Suffering Severe Hip or Knee Osteoarthritis: A Surface Topography Study
This study included three groups of individuals. The first group consisted of 34 patients (15 men and 19 women with a mean age of 67.62 ± 8.28 years) suffering from hip OA. The second group consisted of 45 patients (11 men and 34 women with a mean age of 72.47 ± 7.0 years) suffering from knee OA. These patients were compared with a CG, which consisted of 25 individuals (13 men and 12 women with a mean age of 69.28 ± 10.11 years). The DIERS formetric 4D analysis system was used to calculate several truncal parameters in all planes. All analyses were accomplished using the SPSS ver. 17.0, and p

Comparison of Clinical Outcomes and Complications of Primary and Revision Surgery Using a Combined Anterior and Posterior Approach in Patients with Adult Spinal Deformity and Sagittal Imbalance
Clin Orthop Surg. 2021 Jun;13(2):196-206. doi: 10.4055/cios20217. Epub 2021 Apr 23.ABSTRACTBACKGROUD: The purpose of this study was to compare clinical outcomes and complications of primary and revision surgery in patients with adult spinal deformity (ASD) accompanied by sagittal imbalance. Revision surgery has been associated with poor clinical outcomes and increased risk of complications. Previous studies comparing primary versus revision surgery included data for a wide variety of diseases and ages, but few investigated patients with ASD with sagittal imbalance undergoing anterior and posterior combined surgery.METHODS:...
