Posterior cruciate ligament recruitment affects antero-posterior translation during flexion gap distraction in total knee replacement
BACKGROUND AND PURPOSE Because of the oblique orientation of the posterior cruciate ligament (PCL), flexion gap distraction could lead to anterior movement of the tibia, which would influence the tibiofemoral contact point. This would affect the kinematics of the TKR. We assessed the flexion gap parameters when the knee is distracted during implantation of a PCL-retaining TKR. Furthermore, the ...
متن کاملThe Accuracy of a Robotically-controlled Freehand Sculpting Tool for Unicondylar Knee Replacement
Surgical robotics with navigation has the potential to improve the accuracy of unicondylar knee replacement. Precision freehand sculpting tools allow the surgeon to accurately execute their surgical plan. A controlled study comparing the planned and final placement of uni compartmental knee replacement implants in nine cadavers. A quantitative assessment analysed the translation and rotational ...
متن کاملUnicondylar osteoarticular allografts of the knee.
BACKGROUND In the management of a resected distal femoral or proximal tibial condyle as the result of tumor or trauma, a unicondylar osteoarticular allograft is currently the only reconstructive option that avoids the sacrifice of the unaffected condyle. The purposes of this study were to perform a survival analysis of unicondylar osteoarticular allografts of the knee and to evaluate the compli...
متن کاملThe influence of posterior condylar offset on knee flexion after total knee replacement using a cruciate-sacrificing mobile-bearing implant.
We have studied the concept of posterior condylar offset and the importance of its restoration on the maximum range of knee flexion after posterior-cruciate-ligament-retaining total knee replacement (TKR). We measured the difference in the posterior condylar offset before and one year after operation in 69 patients who had undergone a primary cruciate-sacrificing mobile bearing TKR by one surge...
متن کاملProprioception after unicondylar knee arthroplasty versus total knee arthroplasty.
Proprioception was measured in 2 groups of patients after successful knee arthroplasty. Twenty-eight patients had total knee arthroplasty and their results were compared with an age matched group of 10 subjects who had undergone unicondylar knee arthroplasty. The threshold to detection of passive motion was quantified as a measure of proprioception. The degree of preoperative arthritis was obje...
