Filter by:The purpose of this study is to evaluate the efficacy of an oral methylprednisolone taper on acute postoperative pain, function, opioid consumption, nausea, and complications following outpatient total knee arthroplasty (TKA). We hypothesize that administration of an oral methylprednisolone taper starting on postoperative day 1 (POD 1) following TKA will be associated with improved pain and decreased opioid use, nausea, and complications at POD1-7, as compared to similar patients who receive placebo. Additionally, those taking methylprednisolone will report decreased pain and greater objective functional outcomes at 3 and 6 weeks postoperatively as compared to controls.
The aim of this study is to determine if duloxetine is associated with differences in post-operative pain, patient-reported outcome measures, and opioid consumption in patients undergoing primary total knee arthroplasty compared to patients who do not receive the medication. If so, duloxetine has the potential to become widely incorporated into the multi-modal analgesic regimen given to patients following knee replacements.
Total knee arthroplasty is one of the effective methods for the treatment of end-stage osteoarthritis. Postoperative rehabilitation exercise is an important method for the recovery of knee joint function. Exercise fear refers to an enlarged psychological phenomenon that patients are afraid of sports leading to injury, which is not conducive to the functional exercise of patients and hinders the recovery of knee joint function
Single-shot Adductor Canal Block in the outpatient clinic is safe, significantly decreased pain and analgesic consumption and may enhance the rehabilitation program
The investigators are evaluating the postoperative outcomes in patients undergoing total knee arthroplasty that receive either systemic lidocaine or ultrasound-guided adductor canal block as part of their anesthetic plan.
Total knee arthroplasty (TKA) is one of the success stories of modern surgery, providing high patient satisfaction outcomes. Total knee prostheses are generally composed by a femoral component articulating on a polyethylene insert and a tibial tray. Recently there has been particular attention on the component material; traditionally femoral components are made of cobalt alloys while tibial baseplates are made, in the great majority of cases, of metallic materials, but also polyethylene versions are available. There has been a degree of acceptance in some countries that metal related pathology may exist as demonstrated by the Australian Arthroplasty register where metal hypersensitivity was reported as the fifth most common cause for revision hip arthroplasty 2012 report, making up for 5.9% of all revisions. The wording was subsequently changed from "metal sensitivity" to "metal related pathology" in the 2014 report with 0.5% of all revision total hip arthroplasties (THA) associated with this term. The same change in terminology was used for TKA with metal sensitivity as a cause for revision in 1.3% of revisions in 2012 and in 2014, 1.8% of revision TKAs attributed to "metal related pathology" . The overall revision rate was 3.45% after 10 years in 396.472 TKAs, suggesting a revision rate of 0.06-0.32% secondary to metal or cement allergies. Up to today there is no question that metallic implants may generate wear debris that cause local reactions. This local reaction is not dose related nor predictable and therefore not purely due to the toxic effect of the debris but possibly due to an immunological host process. Hypersensitivity to metal undoubtedly exists but it cannot be stated at the moment to be an allergic reaction. To prevent issues arising due to metal related pathology, alternative solutions to conventional chrome cobalt material have been proposed, for example ceramic component or implant coating. In particular, TiNbN coating has been proposed by most companies thanks to its excellent biological properties. Preclinical studies have showed a high scratch resistance and low coefficient of friction, more resistance to fretting corrosion, reduction of wear, lower ion release rates and low fatigue cycle, as described in the review of Hove. Clinically, cohort of studies of TiN-coated implants showed an overall survival exceeding 90% with a follow-up of 15 to 77 months and good clinical outcomes. No reports of adverse effects related to TiN coating of CoCrMo knee implants have been showed. There are few studies that compared TiN-coated implants with the same uncoated version. Thienpont, comparing TiN-coated and uncoated CoCrMo implants, showed similar clinical and radiological outcomes at short-term follow up in both patients groups . Overall we can conclude that in literature no adverse events have been reported concerning the TiNbN coating and in particular it has been showed that the coating doesn't not affect the performance of the device if compared with the same uncoated version. The aim of this study is to evaluate the long term clinical and radiological performance of GMK Sphere total knee component, coated version.
The objective of this study is to investigate whether the use of virtual reality (VR) during total knee arthroplasty (TKA) can facilitate reductions in intraoperative sedative requirements while maintaining high levels of patient satisfaction as compared to both a music and sham VR + usual care control.
The purpose of this study is to evaluate clinical performance and safety in total knee arthroplasty using HLS implants.
Total knee replacement surgery (TKA) is a treatment for advanced tibial-femoral osteoarthritis. This intervention is justified in case of significant discomfort and failure of medical treatment. It aims to replace the native internal and external femoro-tibial joints with a joint between a femoral implant and a tibial implant. Implants can be cemented or cementless. The longevity of these implants depends among other things on the quality of the bone fixation of the implants. It is therefore essential that this fixation be evaluated. The advantages of an uncemented TKA are the preservation of bone stock, the absence of wear by cement debris and prolonged fixation thanks to osseointegration. These characteristics are all the more interesting in a young population. Numerous studies have been carried out on the survival of TKA with and without cement. The results found are not unanimous and mainly concern the survival of the implants and the presence of radiological signs of loosening. In addition, no study has evaluated the results of TKA with or without cement implanted using robotic assistance. The precision provided by the robotic system could improve the results of these uncemented implants. Very few studies are interested in the functional results according to the cementation or not of TKA. And most of these studies do not have a high level of methodological evidence. We would like to prospectively evaluate the functional results, survival, as well as the rate of radiological border after TKA with or without cement posed with robotic assistance, in the short and medium term.
