Three-dimensional implant position and orientation after total knee replacement performed with patient-specific instrumentation systems.
Patient-specific instrumentation systems are entering into clinical practice in total knee replacement, but validation tests have yet to determine the accuracy of replicating computer-based plans during surgery. We performed a fluoroscopic analysis to assess the final implant location with respect to the corresponding preoperative plan. Forty-four patients were analyzed after using a patient-sp...
متن کامل[Meta analysis of three-dimensional printing patient-specific instrumentation versus conventional instrumentation in total knee arthroplasty].
Objective: To evaluate the effects of three-dimensional printing patient-specific instrumentation(PSI) versus conventional instrumentation(CI) in the total knee arthroplasty. Methods: According to "patient-specific" , "patient-matched" , "custom" , "Instrumentation" , "Guide Instrumentation" , "cutting blocks" , "total knee arthroplasty" , "total knee replacement" , "TKA" and "TKR" , the litera...
متن کاملComparison of planned and achieved implant position in total knee arthroplasty with patient-specific positioning guides
BACKGROUND AND PURPOSE Intraoperatively, patient-specific positioning guides (PSPGs) represent the preoperatively planned alignment. We investigated the degree of correlation between preoperative planning and the alignment achieved postoperatively with the PSPG technique. PATIENTS AND METHODS TKAs performed with the PSPG technique between 2009 and 2011 were included. 39 patients (42 TKAs) vol...
متن کاملEvaluation of implant position and knee alignment after patient-specific unicompartmental knee arthroplasty.
Implant positioning and knee alignment are two primary goals of successful unicompartmental knee arthroplasty. This prospective study outlines the radiographic results following 32 patient-specific unicompartmental medial resurfacing knee arthroplasties. By means of standardized pre- and postoperative radiographs of the knee in strictly AP and lateral view, AP weight bearing long leg images as ...
متن کاملAlignment and component position after patient-matched instrumentation versus conventional total knee arthroplasty.
PURPOSE To compare patient-matched instrumentation (PMI) with conventional total knee arthroplasty (TKA) in terms of limb alignment and component position. METHODS Nine men and 36 women (mean age, 69.5 years) who underwent PMI TKA were compared with 20 men and 25 women (mean age, 69.3 years) who underwent conventional TKA by the same team of surgeons with the same prosthesis and protocols in ...
