Two users performed two registrations of the software workflow on each participant's right and left knees. A force was manually applied to the end-point of varus and valgus knee laxity and the measured change in mechanical alignment was recorded. Force was applied with the knee positioned in ...
Comparison of the joint laxity of total knee arthroplasty evaluated by the distraction force and the varus–valgus force BACKGROUND :Component gap (CG) measurement help surgeons evaluate intraoperative soft-tissue balance. One technique is measuring the CG using tensioner dev... H Inui,R Yamagami,...
An understanding of the normal valgus-varus motion of the knee during stair climbing is needed to apply biomechanical analysis of stair climbing as a evaluation tool for knee osteoarthritis patients. Methods. A motion analysis system, three force plates, and a flight of stairs were used to ...
she has been experiencing anterior knee pain on her left knee and she believes it is associated with her running as she first noticed it about a month after starting her running program. The pain comes on while she is running and does not seem to bother her as much on the days when she...
contact forcesoft tissue balancetotal knee replacementIdentifying and correcting varus﹙algus (V￢) malalignment of the tibial component is important when balancing a kinematically aligned total knee arthroplasty (TKA). Accordingly, the primary objective was to determine whether the tibial forces or V￢...
Varus gonarthritis - High tibial osteotomy - Maquet barrel vault osteotomySurgical PrinciplesIn varus osteoarthritis of the knee the force of weight bearing, which normally passes through the centre of the weight bearing surfaces, is medially displaced [4, 8].In order to redistribute the load ...
The anterior cruciate ligament-deficient knee with varus alignment. An analysis of gait adaptations and dynamic joint loadings Thirty-two patients with an ACL-deficient knee and lower limb varus alignment and 16 healthy controls were analyzed during level walking using a force-plat...

Biomechanical studies in Cadaver knees have shown that with uniform loading 5200-6500 N force is required to produce failure.With eccentric medial loading lateral lift-off failure occurs at 9-15% of the above force and compression load failure on the medial side occurs at 50% of the force.B...
concentrates on the inside of the knee joint; local magnification of the X-ray film showed that the medial joint space was significantly smaller than the lateral joint space, and the local osteosclerosis on the medial side of the joint was significantly greater than that on the lateral side. ...
We assumed that the correction of varus deformity occurred via release of the deforming force by cutting the string of bow. Therefore, HFO decreases the pressure in the medial compartment of the knee, reducing the knee pain and improving the function in patients with medial compartment knee ...
