BACKGROUND There is growing concern about the use of opioids prior to total knee arthroplasty (TKA), and research has suggested that preoperative opioid use may lead to worse pain outcomes following surgery. We evaluated the pain relief achieved by TKA in patients who had and those who had not used opioids use before the procedure. METHODS We augmented data from a prospective cohort study of ...

BACKGROUND Arthritis is a leading cause of disability in the United States. Total knee arthroplasty (TKA) has become the gold standard to manage the pain and disability associated with knee osteoarthritis (OA). Although more than 400,000 primary TKA surgeries are performed each year in the United States, not all individuals with knee OA elect to undergo the procedure. No clear consensus exists ...

Background: In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment ofthe femoral component in total knee arthroplasty (TKA).Methods: There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittalfemoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cor...

Postoperative pseudogout after total knee arthroplasty (TKA) is very rare, and its physical findings are very similar to infectious symptoms. In pseudogout, the mechanism underlying the deposition of calcium pyrophosphate dehydrate crystals remains unclear. Here, we report the histologic findings in a pseudogout attack in the late postoperative period after TKA. She had acute onset of arthritis...

BACKGROUND The projected demand for total knee arthroplasty is staggering. At its root, the solution involves increasing supply or decreasing demand. Other developed nations have used rationing and wait times to distribute this service. However, economic impact and cost-effectiveness of waiting for TKA is unknown. METHODS A Markov decision model was constructed for a cost-utility analysis of ...

PURPOSE: The most feared complication of total knee arthroplasty (TKA) is periprosthetic infection (1–5% of cases) which leads to prosthetic failure and may result in knee fusion or even limb loss. The optimal role of a plastic surgeon in salvaging a compromised TKA remains unclear. We sought to elucidate factors associated with TKA salvage and principles of reconstruction that optimize outcomes.

Total knee arthroplasty (TKA) is a well-established procedure, and has proven to be durable and effective for the treatment of advanced arthritis of the knee joint. Early TKAs did not include patellar replacement and anterior knee pain was reported after the procedure had been carried out. The incorporation of patellar resurfacing during TKA reduces anterior knee pain, although new complication...

This study was intended to investigate into the incidence rates of deep vein thrombosis (DVT) in patients who used prophylactic antithrombotic medications after total knee arthroplasty (TKA), and to compare clinical results in groups treated with Rivaroxaban versus Dalteparin sodium as prophylactic antithrombotic medications. This prospective study was performed in 300 patients who underwent TK...

The aim of our study was to determine the current incidence and outcome of infected total knee arthroplasty (TKA) in our unit comparing them with our earlier audit in 1986, which had revealed infection rates of 4.4% after 471 primary TKAs and 15% after 23 revision TKAs at a mean follow-up of 2.8 years. In the interim we introduced stringent antibiotic prophylaxis, and the routine use of occlusi...

UNLABELLED Anterior knee pain is one of the major short-term complaints after TKA. Since the introduction of the mobile-bearing TKA, numerous studies have attempted to confirm the theoretical advantages of a mobile-bearing TKA over a fixed-bearing TKA but most show little or no actual benefits. The concept of self-alignment for the mobile bearing suggests the posterior-stabilized mobile-bearing...
