BACKGROUND: The infrapatellar fat pad (IPFP) has been implicated as a possible source of osteoarthritis (OA) development and knee pain due to the production of inflammatory mediators and the existence of nerve fibers within this structure. Calcitonin gene-related peptide (CGRP) is a vasodilatory neuropeptide that is localized to joint tissues and has recently been implicated in the development of knee OA and OA pain. To date, however, the expression levels of CGRP in the IPFP of human knee OA patients have not been examined...

BACKGROUND: Total knee arthroplasty (TKA) is associated with high rates of prolonged opioid use after surgery (10%-34%). By decreasing opioid use in the immediate postoperative period, perioperative nerve blockade has been hypothesized to decrease the risk of persistent opioid use. METHODS: Using health care utilization data, we constructed a sample of 120,080 patients undergoing TKA between 2002 and 2012 and used billing data to identify the utilization of peripheral or neuraxial blockade...

BACKGROUND: The cross-sectional morphology of the prosthetic knee is crucial to understanding patellar motion and quadriceps strength after total knee arthroplasty. However, few comparative evaluations of the cross-sectional morphology of the femoral trochlea have been performed in the native knee and currently available femoral implants, and the relationship between the trochlear anatomy of prosthetic components and post-operative patellofemoral complications remains unclear. We aimed to investigate the differences in cross-sectional morphology of the femoral trochlea between native knees and prosthetic femoral components...

For the first six weeks following total knee arthroplasty (TKA), a patient will attend an outpatient clinic typically seen twice weekly. Here, an exercise regime is performed and improvement assessed using a hand held goniometer that measures the maximum angle of knee flexion, an important metric of progress. Additionally a series of daily exercises is performed at home, recorded in a diary. This protocol has problems. Patients must attend the hospital with assistance since they are not permitted to drive for six weeks following the procedure; appointments are sometimes missed; there are occasionally not enough physiotherapy appointment available; furthermore, it is difficult to be sure that patients are compliant with their exercises at home...

BACKGROUND: Disclosing agents are dyes used in dentistry to colorize plaque (biofilm) and may offer a means for intraoperative detection of biofilms on orthopedic implants. Methylene blue (MB) stains biofilm and is safely used in orthopedic applications. Injection of MB into acutely infected prosthetic knees before debridement may enable visualization of biofilm, which could influence treatment decisions. The aims of this study were to determine if MB could be used to visualize biofilm on total knee arthroplasty (TKA) implants and to determine if MB staining has an antimicrobial effect that might interfere with subsequent culture...

BACKGROUND: Tranexamic acid (TXA) has been proven to be effective in reducing blood loss and transfusion rate after total knee arthroplasty (TKA) without increasing the risk of deep vein thrombosis (DVT) and pulmonary embolism (PE). Recently, an increasing number of studies have been interested in applying combined intravenous (IV) with intraarticular (IA) tranexamic acid in total knee arthroplasty. The purpose of this meta-analysis was to compare the blood loss and complications of combined TXA with IV TXA or IA TXA on TKA...

The study aims to explore the effects of TLR-2/NF-κB signaling pathway on the occurrence of degenerative knee osteoarthritis (OA). Degenerative knee OA and normal cartilage samples were collected from patients with degenerative knee OA receiving total knee arthroplasty and amputation. Expressions of TLR-2, NF-κB and MMP-13 were determined by qRT-PCR and immunochemistry. The chondrocytes were divided into control, IL-1β, IL-1β + anti-TLR-2 and IL-1β + PDTC groups. MTT assay and flow cytometry were performed to determine proliferation and apoptosis of the chondrocytes...

Sleep disruption is a common, yet rarely addressed, complaint among patients who have undergone total joint arthroplasty (TJA). This study assessed sleep quality before and after primary TJA. A total of 105 patients who underwent primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) prospectively completed questionnaires during the preoperative, early postoperative, and late postoperative periods. The survey included the Epworth Sleepiness Scale, current sleeping habits, and patient perspectives of sleep quality and duration...

BACKGROUND: Forced-air warming is used as a mechanism to prevent hypothermia and adverse outcomes associated with hypothermia among patients undergoing surgery. Patient safety in healthcare includes the use of devices and technology that minimize potential adverse events to patients. The present study sought to compare the capabilities of patient warming between two different devices that use different mechanisms of warming: forced-air warming and non-air warming. METHODS: One hundred twenty patients undergoing total hip or total knee arthroplasty received patient warming via a forced warming device or non-air warming fabric conductive material...

To the best of our knowledge, the effect of pre-emptively blocking pain transmission on acute postoperative cognitive dysfunction (POCD) has not yet been assessed. Therefore, the present study aimed to investigate the effect of pre-emptive analgesia via a continuous femoral nerve block (CFNB) on postoperative pain and early cognitive function following total knee arthroplasty (TKA) surgery in elderly patients. CFNB was performed prior to TKA surgery in the pre-emptive analgesia group (n=30) and following TKA surgery in the control group (n=30)...

BACKGROUND: As orthopedics transition to value-based purchasing, hospitals and providers are incentivized to identify inefficiencies of care delivery. In our experience, weekends are characterized by decreased staffing of ancillary services to coordinate patient discharges, which can lead to prolonged hospital stays for many of our primary total knee arthroplasty (TKA) admissions. METHODS: We identified 115,053 patients who underwent primary TKA on a weekday between 2009 and 2013 in New York State...

BACKGROUND: The success of revision total knee arthroplasty depends on adequate exposure that does not produce complications. The purpose of this study was to compare the results of revision total knee arthroplasty between V-Y quadricepsplasty (QP) and quadriceps snip (QS) approaches. METHODS: In the study, 92 knees with follow-up of 12-108 months which were operated by using QP (55) and QS (37) were evaluated retrospectively. Measurements were taken by using universal transparent goniometer, also varus valgus deformities, knee flexion angles, instability, Hospital for Special Surgery and Lower Extremity Functional Scale scores, functional condition of the knee and activity levels of the patients were evaluated cross-sectionally...

BACKGROUND: The United States is in the midst of an opioid epidemic. Little is known about perioperative opioid use for total knee arthroplasty (TKA). The purpose of this study was to identify rates of preoperative opioid use, evaluate postoperative trends and identify risk factors for prolonged use after TKA. METHODS: Patients who underwent primary TKA from 2007-2014 were identified within the Humana database. Postoperative opioid use was measured by monthly prescription refill rates...

BACKGROUND: The first biomechanical evaluation of new implants is usually carried out with cadavers. Fixation of Thiel-embalmed cadavers is supposed to preserve the histological structure, colour and consistency of the tissue and has a low risk of infection and toxicity. However, the biomechanical properties of Thiel-fixated tissue are still unknown. The aim of this study was to quantify the effect of the Thiel-embalming method on the elastic properties of the ligament complex of the knee compared to in vivo knees during total knee arthroplasty...

BACKGROUND: The fixation of uncemented tibia components in total knee arthroplasty may rely on the bone quality of the tibia; however, no previous studies have shown convincing objective proof of this. Component migration is relevant as it has been shown to predict aseptic loosening. METHODS: We performed 2-year follow-up of 92 patients who underwent total knee arthroplasty surgery with an uncemented tibia component. Bone mineral density (BMD; g/cm(2)) of the tibia host bone was measured preoperatively using dual energy X-ray absorptiometry...

We report a novel case of a patient who presented for elective total knee arthroplasty and had distorted adductor canal anatomy due to previous sartorius rotational flap surgery. Despite the lack of a sartorius muscle on the intended operative limb, we describe the successful placement of a continuous adductor canal block. This case is a clinically relevant example that highlights the importance of the vastoadductor membrane as the anatomical anteromedial boundary for the adductor canal, and that it remains intact even after sartorius muscle flap surgery...
