“…Using in vitro and in vivo experiments, numerous researchers have recorded tibial translation along the AP direction, as well as an increased angle of IE rotation, which are related to a deficiency of the AC ligament [8,9,14,15]. The results of the studies published so far [7], [10], [16] confirm the findings in our study, shown in Figure 6.…”

“…To achieve the functional role of the AC ligament, it is critical to determine the gait cycle phases that induce pathological kinematics of the knee joint with a deficient AC ligament. Assuming that the AC ligament and posterior cruciate ligament are rigid bodies, knee motion combines two different motions, gliding and rolling [9]. The gliding phase is very important for the determination of the rotation and translation values.…”

Anterior cruciate ligament (ACL) injuries are relatively common in young athletes and quite often require surgical reconstruction. Th e purpose of the ACL reconstruction is to achieve stability in the entire range of motion of the knee and to re-establish a normal gait pattern. For this study, we examined nineteen adult men. Subjects walked along a pathway at their own speed. Motion curves were obtained based on the kinematic data collected using the OptiTrack system with six infrared cameras. Anteriorposterior tibia translation, as the leading ACL pathological parameter, was indirectly determined by monitoring the difference in the length of the distance between markers positioned at the femoral lateral epicondyle and at the tuberosity of the tibia in space and in the sagittal plane. Additionally, the angle of the internal-external rotation was monitored using the gradient of the tangent line of the motion curve. Anterior-posterior tibia translation and internal-external rotation were signifi cantly diff erent after reconstruction surgery compared with preoperational measurements. Preoperational measurements included the maximal values of the AP translation and IE rotation in the early stance phase of the gait cycle. An increase of the AP translation and IE rotation values may cause degeneration of the cartilage. Th ese results reveal that a more precise diagnosis of the ligament instability can be made, providing relevant indicators for the type of treatment.

“…Rotational laxity of the knee is one aspect by which to diagnose knee pathology and to evaluate surgical treatment, such as anterior cruciate ligament (ACL) reconstruction (Georgoulis et al, 2003(Georgoulis et al, , 2005Kanamori et al, 2000;Koh et al, 2005;Logan et al, 2004;Mannel et al, 2004;Musahl et al, 2007;Scopp et al, 2004;Tashman et al, 2004;Yagi et al, 2002;Yamamoto et al, 2004;Zaffagnini et al, 2000). Several methods for measuring in vivo knee and ankle joint kinematics in three dimensions (3D) have now been developed using medical imaging techniques (Bingham and Li, 2006;Fellows et al, 2005b;Kü pper et al, 2007;Siegler et al, 2005;Tashman and Anderst, 2003;Udupa et al, 1998;Van Sint Jan et al, 2006).…”

“…Therefore, to classify knee joint as a ginglymus joint is a massive over-simplification of the joint. There have also been reports stating that the knee joint has six degrees of freedom, namely, flexion-extension, internal-external rotation, valgus-varus rotation, anterior-posterior translation, medial-lateral translation and compression-distraction translation [40,50].…”

Investigation of the intrameniscal forces : experiment on porcine knee joints and formulation of mathematical models

Mechanisms of the knee joint have always been of interest to orthopaedic surgeons, prosthesis designers and biomechanical engineers. Meniscal injuries are common and the impact of such injuries on the patients is tremendous. Therefore, it is of great interest to investigate the load transmission mechanism in the knee and especially in the menisci. In this project, the load transfer mechanism was investigated through the direct measurement of the intrameniscal forces of the porcine knee joint using miniature sensors. Such attempts will provide quantitative indications into the load distribution and provide insights into the failure mechanism of the natural knee. In this report, variation of intrameniscal stress with joint angulations, applied torque and time were determined. This approach is unique as there has been no attempt in measurement of the forces inside the meniscus. In addition, mathematical models of the articular cartilage and meniscus are derived to explain the variation of intrameniscal stress with time. From the investigations done on the intrameniscal force, it was found that measurement of intrameniscal force is possible. In a porcine knee joint, anterior region of the lateral meniscus experienced high stresses during hyperextension. During hyperflexion, posterior regions of both lateral and medial menisci were under high stresses. Anterior region of the lateral meniscus was under highest stresses during external rotation and posterior region of the lateral meniscus was under highest stresses during internal rotation of the knee joint. In general, higher stresses were observed during external rotation as compared to internal rotation of the porcine knee. Highest stresses typically occur in extreme joint positions (hyperextension, hyperflexion, internal rotation and external rotation) and these suggest that extreme positions with high applied torque and a combination of extreme positions on the knee joint should be avoided. Experimental results for variation of intrameniscal stress with time implied that there was a load transfer from articular cartilage to meniscus with time. This load shift behaviour will protect the articular cartilage if the knee joint is under static loading. This stress versus time behaviour can be explained by a viscoelastic power-law model.
