Filter by:Peri-articular knee infiltration with Levobupivicaine 150mg, Morphine 10mg and Ketorolac 30mg reduces postoperative pain following primary total knee replacement compared with the current standard treatment of femoral nerve blockade.
The hypothesis of this study is that total knee alignment will be improved by preoperative planning from CT scans and the production of custom instruments compared to the use of standard instruments.
The main purpose of this study is to determine whether the surgical time required for primary total knee arthroplasty is significantly less when performed with Customized Patient Instrumentation (CPI) than with conventional instrumentation. Each case will be recorded by video camera, in order to time the length of surgery and each surgical step. The number of surgical trays required for each case will be recorded. As an additional endpoint, the investigators will measure limb and component alignment on x-rays to determine if these two methods achieve equivalent alignment results. The thickness of bone cuts will be compared to the surgical plan and to each other. The primary hypothesis is that the use of customized patient instrumentation will reduce the operative time required for total knee arthroplasty.
Objective: The purpose of this study is to evaluate the application of computer-assisted navigation in Total Knee Arthroplasty (TKA ) by comparing it with conventional TKA. Methods: Gemini MK II implants (Link, Germany) were used. VectorVisionâ CT-free navigation system (BrainLab, Germany) was employed for the TKA. For each subject, computer-navigation TKA and the conventional TKA were separately performed on two knee joints. The operative method and order of the operations were decided on a randomized basis. All the patients and doctors conducting follow-up study and performing imaging measurement were blind to selection of the operation. Student t test was used for statistical analysis. hypothesis: computer-assisted navigation system can significantly improve the accuracy of tibial and femoral cuts on coronal and sagittal planes.
The purpose of this study is to determine whether a computer navigational unit can improve operating time and consistency during Knee arthroplasty when compared to knee arthroplasty without a computer navigational unit.
The purpose of the study is to analyse the clinical and radiological results of a postero-stabilized TKA by using a mobile bearing versus fixed. Only patients with medial femorotibial arthritis will be included. The consequences on the patellofemoral joint will be thoroughly analysed on skyline view.
