background: malnutrition has been linked to poor outcomes after elective joint arthroplasty, but the risk of unplanned postoperative intensive care unit (icu) admission in malnourished arthroplasty patients is unknown. methods: 1098 patients were followed as part of a prospective risk stratification program at a tertiary, high-volume arthroplasty center. chronic malnutrition was defined as preo...

Significant controversy exists in the literature regarding the pitfalls and benefits of minimally invasive total knee arthroplasty (TKA). Regardless, most surgeons today use smaller exposures than in previous years. Although more difficult, rigid adherence to classical gap balancing techniques can allow a surgeon to achieve ideal ligament and flexion/extension gap balance in TKA through a minim...

abstract  background: in the recent decade, many primary total knee arthroplasties have  been carried out in iran and the number of revision cases is expected to rise with the  aging population. the aim of this study was to report the outcome of revision surgery  in the country and make a comparison between the outcome of revision and that of  the primary arthroplasty.  methods: retrospectively...

despite improvements in surgical and anesthetic techniques, total joint arthroplasty (tja) is still associated with substantial blood loss and postoperative anemia (1). a considerable portion of patients with postoperative anemia require blood transfusion, which has been shown to negatively affect the outcome of tja and predisposes patients to development of surgical site infection and peripros...

BACKGROUND AND PURPOSE Restoration of mechanical alignment after total knee arthroplasty can be achieved with ligament releases. Several previously described sequences and results achieved with cadaver knees, with measured resection implantation techniques, may not be applied to the balanced gap technique. We investigated the peroperative effect of stepwise soft tissue releases following the "t...

Introduction One of important factors to achieve stable postoperative results is to obtain proper soft tissue balance at the time of total knee arthroplasty (TKA). With a goal of accurate gap balance during TKA, we developed a tensor called Joint Dependent Kinematics (JDKmini II, Stryker, Tokyo, Japan) and presented the tensor in this meeting last year. Computer navigation has been proven to be...
