BACKGROUND: An increased perioperative complication rate has been a concern with one-stage bilateral total knee arthroplasty (TKA). The purpose of this study was to retrospectively investigate the perioperative safety and clinical results of one-stage bilateral TKA in selected low-risk patients. METHODS: Sixty-seven patients who received one-stage bilateral TKAs for osteoarthritis who were American Society of Anesthesiology (ASA) class 1 or 2 were included in this study...

Abnormal kinematics and kinetics have been reported in hip osteoarthritis (OA) patients before and after total hip arthroplasty (THA). These changes can affect the loading of the ipsilateral hip, as well as the contralateral hip and knee joint. As it is not clear how hip and knee loading evolves in THA patients during the first year after surgery, the goal of this study is to define how joint loading changes in patients before and at three evaluation times after THA surgery. Musculoskeletal modelling in combination with gait analysis data was used to calculate hip and knee contact forces in 14 patients before and 3-, 6- and 12-months after unilateral THA, as well as in 18 healthy controls...

PURPOSE: One of the complications in total knee arthroplasty (TKA) is pseudo-patella baja (PPB). PPB is present when there is no shortening of the patellar tendon, but the joint line is elevated. The purpose of this study is to investigate the incidence of PPB after TKA and its clinical effects. METHODS: A case series of 158 patients undergoing TKA surgery between 1999 and 2012 at the 2nd Department of Orthopaedics and Traumatology, Pisa were retrospectively reviewed...

CASE: A 64-year-old woman had undergone bilateral total knee arthroplasty in 1998. In 2010, she presented with a large, painless, diaphyseal soft-tissue mass of the lower leg. She indicated that she had no history of knee pain, trauma, or infection. Ultimately, the mass was found to be a synovial fluid-filled cyst that communicated with the knee joint, which was a result of severe osteolysis. CONCLUSION: Large diaphyseal tibial masses in the presence of total knee arthroplasty should raise a high index of suspicion not only for tumors and infections, but also for severe osteolysis...

BACKGROUND: In total knee arthroplasty (TKA), handling of the patella surface is still quite controversial. We carried out a prospective randomized study to compare circumpatellar electrocautery plus patella resurfacing vs circumpatellar electrocautery only in the single-staged bilateral TKA in Chinese population. METHODS: One hundred five patients diagnosed with late-staged osteoarthritis who received single-staged bilateral TKA were screened and 53 patients were included...

BACKGROUND: The use of intravenous acetaminophen has seen recent enthusiasm as one component of a multimodal approach to pain management. However, there is a lack of literature examining the efficacy of intravenous acetaminophen for pain control in total joint arthroplasty. The purpose of this study was to evaluate the efficacy of intravenous acetaminophen following primary total knee arthroplasty. METHODS: This is a retrospective review of 38 patients undergoing primary total knee arthroplasty by a single surgeon at one institution...

Background: Although an increased life expectancy has been previously reported in patients with osteoarthritis (OA) after undergoing total knee arthroplasty (TKA), the long-living Japanese population may provide a more accurate cohort for determining 10- and 15-year survival rates. The aims of the present study were to (1) determine the survival of patients after TKA, (2) identify the factors important for survival, and (3) compare the survival rate of the OA patients with that of the standardized general population...

BACKGROUND: Total knee arthroplasty (TKA) is associated with a risk of thromboembolism requiring routine thromboprophylaxis, but there is debate about the risk with unicondylar knee arthroplasty (UKA) as it is a more minor procedure. We sought to investigate the relative risk of thromboembolism with UKA compared to TKA and one-staged bilateral TKA (BTKA) by measuring the increase in circulating biochemical markers of thrombin generation during the procedures. Degree of surgical trauma was also assessed by measuring interleukin-6, a marker of metabolic injury...

RATIONALE: Arterial injuries during total knee arthroplasty (TKA) though rare may occur. Hemophilia may further challenge the management of such injury. PATIENT CONCERNS: A 48-year-old male patient with severe hemophilia type A and stiff knee arthropathy underwent bilateral TKAs. Left popliteal artery injury was detected at the end of the left TKA. DIAGNOSES: Urgent angiography confirmed the diagnosis of the left popliteal artery transection...

A 70-year-old Indian woman, who had undergone primary bilateral total knee arthroplasty (TKA) for rheumatoid arthritis 10 months prior, presented with 10 days history of pain, swelling and erythema over both knees with pus discharging from the right knee. She had type 2 diabetes mellitus and was on long-term steroid, leflunomide and antitumour necrosis factor therapy for rheumatoid arthritis. Her clinical and laboratory features were suggestive of a haematogenous periprosthetic joint infection (PJI). The final diagnosis of bilateral Salmonella typhi PJI was made based on culture reports...

Although acute ischemic stroke (AIS) is a feared medical complication after total knee arthroplasty (TKA), little is known about its incidence and risk factors. The purpose of this retrospective populationbased study using the Nationwide Inpatient Sample (2008-2011) was to determine the incidence and predictors of AIS following TKA. The rate of perioperative AIS was 0.08%. Patients undergoing bilateral TKA were almost three times more likely to develop AIS compared with unilateral TKA patients. The age group with the highest odds of AIS was ≥85 years...

PURPOSE: To determine the incidence and to identify potential risk factors for in-hospital and late infections, as well as for deep periprosthetic joint infection (PJI) following TKA. METHODS: We identified 17,959 patients treated with primary TKA between 2000 and 2009. We recorded patient demographics, comorbidities and in-hospital complications. The rates of in-hospital, late, and deep PJIs were determined. Different logistic regression models were built to identify risk factors for each of the above types of infection...

Introduction: Recent studies have shown that in addition to patient factors, surgeon volume has influenced total knee arthroplasty (TKA) outcomes greatly. With recent propositions of regionalization of arthroplasties to higher volume centers, the need for further evidence is warranted. Materials and methods: Retrospective Cohort Study done at Aga Khan University Hospital, Pakistan from January 2007 to December 2015. High Volume (HV) group was set as at least 50 TKAs/year and Low Volume (LV) was set as at most 25 TKAs/year...

BACKGROUND: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are currently grouped under the same Diagnosis-Related Group (DRG). With the introduction of bundled payments, providers are accountable for all the costs incurred during the episode of care, including the costs of readmissions and management of complications. However, it is unclear whether readmission rates and short-term complications are similar in primary THA and TKA. METHODS: The National Surgical Quality Improvement Project database was queried from 2011 to 2015 to identify 248,150 primary THA/TKA procedures using Current Procedural Terminology codes...

BACKGROUND: Simultaneous bilateral total knee arthroplasty (SBTKA) offers significant socioeconomic benefits. However, retrospective studies and public health data show increased mortality and morbidity rates in patients undergoing SBTKA compared with those undergoing unilateral TKA (UTKA), and there have been recommendations against the use of SBTKA. High-volume centers, which feature careful patient selection and fast-tracked surgery, continue to perform SBTKA and have published their results in favor of the procedure...
