Accuracy of Patient Specific Cutting Blocks in Total Knee Arthroplasty
BACKGROUND Long-term survival of total knee arthroplasty (TKA) is mainly determined by optimal positioning of the components and prosthesis alignment. Implant positioning can be optimized by computer assisted surgery (CAS). Patient specific cutting blocks (PSCB) seem to have the potential to improve component alignment compared to the conventional technique and to be comparable to CAS. METHOD...
متن کاملPreliminary experience with the patient-specific templating total knee arthroplasty
BACKGROUND AND PURPOSE Patient-specific templating total knee arthroplasty (TKA) is a new method for alignment of a total knee arthroplasty that uses disposable guides. We present the results of the first 40 consecutive patients who were operated on using this technique. METHODS In this case-control study, we compared blood loss, operation time, and alignment of 40 TKAs performed using a pati...
متن کاملComputer-assisted total knee arthroplasty using patient-specific templating.
Current techniques used for total knee arthroplasty rely on conventional instrumentation that violates the intramedullary canals. Accuracy of the instrumentation is questionable, and assembly and disposal of the numerous pieces is time consuming. Navigation techniques are more accurate, but their broad application is limited by cost and complexity. We aimed to prove a new concept of computer-as...
متن کاملPatient-specific guide for revision of medial unicondylar knee arthroplasty to total knee arthroplasty
BACKGROUND AND PURPOSE Unicompartmental to total knee arthroplasty revision surgery can be technically demanding. Joint line restoration, rotation, and augmentations can cause difficulties. We describe a new technique in which single-way fitting guides serve to position the knee system cutting blocks. METHOD Preoperatively, images of the distal femur and proximal tibia are taken using CT scan...
متن کاملFunctional Outcome Study in Total Knee Arthroplasty
Objective: The aim of this study was to validate the well-recognized outcome measure instruments (Medical Outcome Study Short Form-SF-36, Western Ontario and McMaster University Osteoarthritis Index-WOMAC, McMaster Toronto Arthritis Patient Preference Disability Questionnaire-MACTAR) for patients who had undergone total knee arthroplasty in Iran, with its cultural and ethnic differences and com...
