Posterior cruciate ligament recruitment affects antero-posterior translation during flexion gap distraction in total knee replacement

Posterior cruciate ligament recruitment affects antero-posterior translation during flexion gap distraction in total knee replace- ment An intraoperative study involving 50 patients

Posterior cruciate ligament balancing in total knee replacement: the quantitative relationship between tightness of the flexion gap and tibial translation.

We have examined the relationship between the size of the flexion gap and the anterior translation of the tibia in flexion during implantation of a posterior cruciate ligament (PCL)-retaining BalanSys total knee replacement (TKR). In 91 knees, the flexion gap and anterior tibial translation were measured intra-operatively using a custom-made, flexible tensor-spacer device. The results showed th...

Posterior cruciate ligament removal contributes to abnormal knee motion during posterior stabilized total knee arthroplasty.

Abnormal anterior translation of the femur on the tibia has been observed in mid flexion (20-60 degrees ) following posterior stabilized total knee arthroplasty. The underlying biomechanical causes of this abnormal motion remain unknown. The purpose of this study was to isolate the effects of posterior cruciate ligament removal on knee motion after total knee arthroplasty. We posed two question...

The effect of distal femoral bone cut on flexion gap in cruciate retaining total knee arthroplasty -A cadaveric study-

INTRODUCTION: Proper bone cut and soft tissue balancing are the most critical procedures in total knee arthroplasty (TKA). A gap balancing technique is commonly used in TKA to create an equal extension and flexion gap. However, obtaining a flexion gap sufficiently large for the extension gap in cruciate retaining (CR) TKA is sometimes difficult and the flexion gap in CR TKA tends to be smaller ...

Criteria for preserving posterior cruciate ligament depending on intra-operative gap measurement in total knee replacement

OBJECTIVES Because posterior cruciate ligament (PCL) resection makes flexion gaps wider in total knee replacement (TKR), preserving or sacrificing a PCL affects the gap equivalence; however, there are no criteria for the PCL resection that consider gap situations of each knee. This study aims to investigate gap characteristics of knees and to consider the criteria for PCL resection. METHODS T...
