Posterior Stabilized Total Knee Arthroplasty
The posterior cruciate ligament (PCL) in total knee arthroplasty (TKA) functions to prevent posterior translation of the tibia and aids in femoral roll-back1. Roll-back allows for increased quadriceps lever arm and more efficient use of extensor musculature, permitting more normal stair climbing. Because of this, PCL retaining knees have the advantage of maintenance of ligamentous proprioceptio...
متن کاملEffect of Medial and Lateral Posterior Condylar Offset on Knee Flexion after Mobile-bearing Total Knee Arthroplasty.
after Mobile-bearing Total Knee Arthroplasty +Ishii, Y; Noguchi, H; Takeda, M; Sato, J +Ishii Orthopaedic & Rehabilitation Clinic, Gyoda, Saitama, JAPAN [email protected] INTRODUCTION: Postoperative studies using X-ray analyses have reported contradictory findings regarding whether PCO had an effect on flexion after total knee arthroplasty (TKA), since correctly recognizing which condyle ref...
متن کاملPosterior condylar offset is an independent predictor of functional outcome after revision total knee arthroplasty
OBJECTIVES Preservation of posterior condylar offset (PCO) has been shown to correlate with improved functional results after primary total knee arthroplasty (TKA). Whether this is also the case for revision TKA, remains unknown. The aim of this study was to assess the independent effect of PCO on early functional outcome after revision TKA. METHODS A total of 107 consecutive aseptic revision...
متن کاملBiomechanical Effects of Posterior Condylar Offset and Posterior Tibial Slope on Quadriceps Force and Joint Contact Forces in Posterior-Stabilized Total Knee Arthroplasty
This study aimed to determine the biomechanical effect of the posterior condylar offset (PCO) and posterior tibial slope (PTS) in posterior-stabilized (PS) fixed-bearing total knee arthroplasty (TKA). We developed ±1, ±2, and ±3 mm PCO models in the posterior direction and -3°, 0°, 3°, and 6° PTS models using a previously validated FE model. The influence of changes in the PCO and PTS on the bi...
متن کاملChanges in Femoral Posterior Condylar Offset, Tibial Posterior Slope Angle, and Joint Line Height after Cruciate-Retaining Total Knee Arthroplasty.
PURPOSE Changes in the femoral posterior condylar offset (PCO), tibial posterior slope angle (PSA), and joint line height (JLH) after cruciate-retaining total knee arthroplasty (CR-TKA) were evaluated to determine their influence on the flexion angle. MATERIALS AND METHODS A total of 125 CR-TKAs performed on 110 patients were retrospectively reviewed. Pre- and postoperative PCO, PSA, and JLH ...
