“…The femur and tibia were modeled as rigid structures, which greatly reduced the computational time and has been shown to have minimal effect on the model predictions [1,4,6,9,23,[29][30][31][32][33][34][35][36][37][38][39]. Articular cartilage is known to be an anisotropic, biphasic material with a time constant approaching 1500 s [40,41].…”

“…It has been shown that under this condition, the biphasic response of cartilage can be negligible and the single-phase linear isotropic constitutive law be applicable [40,41]. Therefore, cartilage was modeled as a homogeneous, elastic, linearly isotropic material [1,2,[4][5][6][7]9,16,23,25,30,32,33,[35][36][37][38][39][42][43][44][45][46] with a modulus of 15 MPa [4,9,25,30,35,45] and a Poisson's ratio of 0.46 [31][32][33]47,48].…”

“…Previous in vivo tibiofemoral (TF) FE modeling efforts have created models without sufficiently considering the functional joint kinematics involved in the joint loading process [4,5]. Studies have incorporated skeletal kinematics from either nonsubject-specific data [6][7][8] or skin surface marker measurements [9,10]-the latter are prone to soft-tissue artifacts [11] due to marker movement [12,13] and inaccurate marker positioning on the skin relative to the bone [14,15].…”

In this paper, we present a new methodology for subject-specific finite element modeling of the tibiofemoral joint based on in vivo computed tomography (CT), magnetic resonance imaging (MRI), and dynamic stereo-radiography (DSX) data. We implemented and compared two techniques to incorporate in vivo skeletal kinematics as boundary conditions: one used MRI-measured tibiofemoral kinematics in a nonweight-bearing supine position and allowed five degrees of freedom (excluding flexion-extension) at the joint in response to an axially applied force; the other used DSX-measured tibiofemoral kinematics in a weight-bearing standing position and permitted only axial translation in response to the same force. Verification and comparison of the model predictions employed data from a meniscus transplantation study subject with a meniscectomized and an intact knee. The model-predicted cartilage-cartilage contact areas were examined against "benchmarks" from a novel in situ contact area analysis (ISCAA) in which the intersection volume between nondeformed femoral and tibial cartilage was characterized to determine the contact. The results showed that the DSX-based model predicted contact areas in close alignment with the benchmarks, and outperformed the MRI-based model: the contact centroid predicted by the former was on average 85% closer to the benchmark location. The DSX-based FE model predictions also indicated that the (lateral) meniscectomy increased the contact area in the lateral compartment and increased the maximum contact pressure and maximum compressive stress in both compartments. We discuss the importance of accurate, task-specific skeletal kinematics in subject-specific FE modeling, along with the effects of simplifying assumptions and limitations.

An avulsion of the posterior tibial insertion of the lateral meniscus occurs during rotational distortion of the knee and can be associated with a tear of the anterior cruciate ligament (ACL). We performed a follow-up of 28 patients who, following anatomical ACL reconstruction using the ipsilateral semitendinosus graft, underwent either transosseous repair of the posterior lateral meniscus root (n=14) or no intervention (n=14). The meniscus root tears were classified as Forkel I lesions. All patients were examined 6 months after surgery and undertook scoring using International Knee Documentation Committee Score (IKDC). Comparing the repair group with the no repair group the subjective IKDC 6 months after surgery was 75,72% (±1,019) and 75,56 (±1,058). Regarding the objective IKDC 8 × A (57,1%) and 6 × B (42,9%) could be ascertained in the repair group whereas 6 × A (42,9%), 6 × B (42,9%), and 2 × C (14,3%) scoring could be ascertained in the no repair group. It remains unclear if surgery on type Forkel I PLMRT provides benefits compared to the nonsurgical procedures as in both groups stability might occur. The purpose of this article was to report the outcome of surgical repair of lateral meniscus root tears.
