BACKGROUND The antifibrinolytic tranexamic acid reduces surgical blood loss, but studies have not identified an optimal regimen. QUESTIONS/PURPOSES We studied different dosages, timings, and modes of administration to identify the most effective regimen of tranexamic acid in achieving maximum reduction of blood loss in TKA. METHODS We prospectively(More)
Supracondylar fracture above a total knee arthroplasty with a posterior cruciate-substituting design presents a challenging problem to the orthopaedic surgeon. The standard treatment using a intramedullary rod is made difficult by the design of the PFC cruciate-substituting total knee arthroplasty (Johnson & Johnson Orthopaedics, Raynham, MA), which(More)
We analyzed alignment of 300 knees, divided equally into groups according to total knee arthroplasty technique: Conventional, CAS-Early (computer-assisted surgery during the surgeon's learning curve), and CAS-Late (after experience with CAS). With the margin of error for alignment of the mechanical axis and femoral and tibial components each within ±3°, the(More)
PURPOSE Internet addiction (IA) is an upcoming and less researched entity in psychiatry, especially in low and middle income countries. This is the first such effort to study IA amongst Indian school students of class 11th and 12th and to find its correlation with socio-educational characteristics, internet use patterns and psychological variables, namely(More)
Continuous passive motion (CPM), though of doubtful value, is yet routinely practiced post-total knee arthroplasty (TKA). We prospectively distributed 84 patients with TKA to 1 of the 3 standard rehabilitation regimes: no-CPM, 1-day-CPM, and 3-day-CPM. We recorded a unique "Timed up and go" test besides pain, Western Ontario and McMaster Universities(More)
We prospectively enrolled 48 patients (53 knees), scheduled for high-flex posterior-stabilized rotating platform knee implant arthroplasty (PFCΣRPF) to our study. Performance of this implant, introduced in 2005, has been reported upon only up to 2 years. We report its 2- to 6-year postoperative clinical and radiographic results in 47 patients (52 knees).(More)
Rotating-platform knee implants have successively undergone modifications to improve postoperative flexion. The cruciate-sacrificing Low Contact Stress (LCS) implant (DePuy Orthopaedics, Inc, Warsaw, Indiana) was modified into the cruciate-substituting PFC Sigma RP (ΣRP) implant and further into the PFC Sigma RPF (ΣRPF) implant (DePuy Orthopaedics, Inc).(More)
We reviewed 47 patients following operatively treated ankle fracture-dislocation, at an average of 15 months after injury, to assess the outcome of two different postoperative regimens. Of the 47 patients, 27 received early active and passive ankle exercises, and 20 patients received immediate plaster splintage. Patients were assessed clinically by an(More)
"Patient Specific" technology introduced in last 5 years, slowly gained popularity but has currently plateaued. We have a number of studies on patient specific instruments where they have been compared with conventional jigs in total knee arthroplasty and reported to have no clear additional benefits. This review discusses their intraoperative and(More)
