“…It was shown in an in vitro study that tibio‐femoral compression in conjunction with forceful flexion and torsion of the knee can cause vertical‐longitudinal lesions [16]. The knees were twisted maximally in this study, while we used only a moderate torque.…”

Tensile strength is the most often reported parameter in biomechanical investigations of meniscal repair techniques. However, the magnitude of the tensile forces that actually occur on repaired lesions is not clear. The purpose of this study was to investigate if tensile forces occur on repaired lateral meniscal lesions, which could exceed the failure strength of common repair techniques. In human knees (n = 6), vertical-longitudinal lesions 25 mm in length were created in the posterior horn of the lateral meniscus at a distance of 3 mm from the meniscosynovial junction and the popliteal hiatus. A braided steel wire, resembling a vertical suture, was inserted into the meniscal tissue and fitted with a force transducer. The knees were mounted in an apparatus, which simulated weight bearing and non-weight bearing conditions. Repeated measurements were conducted with both internal and external rotation at flexion angles of 0 degrees , 30 degrees , 60 degrees , 90 degrees and 120 degrees . Weight loading alone caused no tension on the suture. Combined flexion and rotation generated mean forces between 0.5 and 4.1 N. No significant effect of the flexion angle or direction of rotation was found. If a minimum strength of 10 N was assumed for the common meniscal repair techniques, the tensile forces were well below this limit under all circumstances (P < 0.001). These data indicate that, within the range of motion investigated, no significant tensile forces occur on longitudinal lateral lesions. Forces other than tension and biological factors are of greater importance for the healing. Therefore, the assessment of repair techniques should not be based on alone the ability to resist high distraction forces.

“…Ishibashi 20) showed that ascent from a squat was a risk factor for knee osteoarthritis in Japanese. Another report has shown that meniscal injuries may occur when the knee is subject to rotation under physiological pressure during deep knee flexion 21) . Such movement during knee flexion may cause damage to both the meniscus and the cartilage in the femorotibial joint.…”

“…According to clinical studies on patients with knee osteoarthritis in Japan, it would appear that the movement of the menisci in deep knee flexion may have a bearing on meniscal injuries, and that those injuries themselves may be followed by knee osteoarthritis [17][18][19][20][21] . Therefore, we believe it is important to investigate the mechanism involved in the movement of the menisci during deep knee flexion in normal persons.…”

Accurate in vivo data concerning the movement of the menisci through the full range of motion of the knee joint are lacking. Using a superconductive open-type magnetic resonance (MR) imaging system, we investigated the movement and morphological changes of the menisci during non-weightbearing deep knee flexion. In 20 healthy adult subjects (mean age, 21.5 years), the knee was moved from 0° to passive maximal flexion (mean angle, 147°), and sagittal images of the knee were taken using a superconductive open-type MR system. In each meniscus, backward movement distance during deep knee flexion and the ratio of anteroposterior internal diameter at deep flexion to that at extension were calculated. For both menisci, the backward excursion of the anterior horn was significantly greater than that of the posterior horn. No difference was significant between the excursion of the anterior horn of the medial meniscus and that of the lateral meniscus during deep knee flexion, but the excursion of the posterior horn of the lateral meniscus was significantly greater than that of the medial meniscus. When the knee was deeply flexed, the anteroposterior diameter of the meniscus was significantly reduced for both the medial and lateral menisci, as compared with the diameter when the knee was extended. In young healthy individuals, the movement and morphological changes of the menisci during deep knee flexion suggest that the menisci might adapt to the environment formed by the combination of the femoral condyles and tibial plateaus throughout the full range of motion.
