The resulting physiological distribution of articular forces protects the acetabular bone and provides optimal conditions for ingrowth, with subsequent long-term component fixation.
The extent of bubble formation within the joint space depends on the articular forces and the vapor pressure of the synovial fluid.
In this study, we investigated the distinctions in intra-articular force distribution between the two types of TKA designs in patients with varus knee osteoarthritis.
Although both the posterior stabilized and cruciate retaining total knee arthroplasty have been proven to effectively relieve pain and restore basic functions, the joint gap width during flexion was reported to be different due to the presence or absence of posterior cruciate ligament, which may lead to different intra-articular force distribution.
This study presents a simultaneous in vivo measurement of tibiofemoral articular contact forces and contact kinematics in three TKA patients.
The current study compares the technique to an innovative approach using a pulsed-pressure perfusion system termed a joint simulating device (JSD), intended to simulate intra-articular mechanical forces.
For these patients, splint therapy may help to position the condyle to a more structurally compatible and functional position and to decrease the loading force of articular surfaces.
Mechanical injury to cartilage, such as articular cartilage crushing, shearing force injury, would result in elevated ROS generation in mitochondria and promotes chondrocyte death [ 77].
However, compared to hammering on the curved osteotome, which could cause an intra-articular fracture, the pulling force applied to the Gigli saw cannot cause this potentially disastrous complication.
This lesion clinically corresponded to an articular block with a forced valgus deviation of the limb and, specifically, to a cutaneous retraction at the level of the joint line.
