Trochlear Thickness and Its Effect on the Outcomes of Total Knee Arthroplasty
In Brief
An observational study evaluating CT trochlear thickness change for Knee Osteoarthritis. Completed, enrolled 87 participants across 1 site.
Detailed Summary
Total knee arthroplasty (TKA ) is the gold standard treatment for advanced knee osteoarthritis. only 85% (75% to 92%) of patients with total knee arthroplasty are satisfied with their operations and 30% develops patellofemoral complications. Numerous biomechanical studies suggest that patellofemoral tracking is not always restored to physiological values, because the prosthetic trochlea may differ from the native trochlea. no study has been con-ducted to investigate the thickness of the trochlear groove and its effect on the outcome of Total knee replacement (TKR), So many people has different measurements of trochlear thickness which may affect Patellofemoral joint (PFJ) so knowing of native trochlear thickness in patients with KNEE Osteoarthritis (OA) can affect the outcomes of total knee arthroplasty.
Study Details
Timeline
Interventions
Preoperative and postoperative CT scan measuring trochlear thickness of PFJ was defined as distance from deepest part of trochlea and line tangential to the anterior aspect of the femoral cortex. It was assessed on the sagittal cuts. CT images will be viewed using Sante DICOM viewer version 5.4.2 and image fusion will be done using Overlay multiple image software. Two observers will measure the angles and the intraobserver and interobserver reliabilities will be assessed for consistency by the intraclass correlation coefficient (ICC) and reliability coefficient using the SPSS software
