Tibial plateau fractures (TPFs) are complex injuries around the knee caused by high- or low-energy trauma. In the present study, we aimed to define the distribution and frequency of TPF lines using a 3D mapping technique and analyze the rationalization of divisions employed by frequently used classifications. In total, 759 adult patients with 766 affected knees were retrospectively reviewed. The TPF fragments on CT were multiplanar reconstructed, and virtually reduced to match a 3D model of the proximal tibia. 3D heat mapping was subsequently created by graphically superimposing all fracture lines onto a tibia template.Aims
Methods
The aim of this study was to compare the accuracy of limb alignment and component positioning after total knee arthroplasty(TKA) performed using fixed or individual distal femoral valgus correction angle(VCA)in valgus knees. One hundred and twenty-four patients were randomised to undergo TKA with either of the clinical baseline, radiological outcomes and subsequent outcome such as knee HSS scores, knee range of motion (ROM) and visual analogue scale (VAS) scores were assessed. Knees in the individual group (n=62) were performed with a tailored VCA. Knees in the fixed group (n=62) were performed utilizing a 4°VCA.Purpose
Materials and Methods
Recently many authors have questioned the role of tourniquets in primary knee arthroplasty (TKA). Meanwhile, whether the use of an intra-articular wound drainage is an advance over the lack of a drain in TKA is controversial in the literature. This study aimed to investigate the efficacy and safety of drainage or not in TKA without a tourniquet. Eighty participants who underwent primary unilateral TKA were prospectively enrolled and were randomized to one of two techniques during surgery without a tourniquet: drainage (Group A) or non-drainage (Group B). Blood loss was monitored perioperatively. The operating time, allogeneic blood transfusion rate, thigh pain, knee pain, limb swelling, clinical outcome as measured by the hospital for special surgery (HSS) score, the ability to straight-leg raise, visual analog scale (VAS) in pain, length of stay and knee active range of motion (ROM) were also recorded. The digital radiographs taken at 6 months postoperatively were assessed for cement mantle thickness and radiolucency using the Knee Society radiographic zones.Purpose
