“…Biomechanically, the single-strand plantaris tendon has a much lower ultimate load compared to the peroneus longus and Achilles tendons due to the plantaris tendon's small cross-sectional area ( 17 ). However, the biomechanical properties of the double-folded plantaris tendon are comparable to those of the original medial patellofemoral ligament, and thus the plantaris tendon may be suitable for medial patellofemoral ligament reconstruction ( 9 ). The plantaris tendon displays excellent biomechanical properties for anterolateral ligament (ALL) reconstruction ( 18 ).…”

“…Reconstruction of the collateral ligaments using various types of grafts has been reported (1,(5)(6)(7). Interestingly, the plantaris tendon has been used for the reconstruction of the anterolateral ligament of the ankle, the medial collateral ligament of the knee, and the Achilles tendon (8)(9)(10)(11)(12). However, there is a lack of literature on the reconstruction of the lateral collateral ligament using the plantaris tendon after wide excision of a malignant soft tissue sarcoma.…”

Reconstruction of the lateral collateral ligament using the plantaris tendon after wide excision of soft tissue sarcoma of the knee: A case report

et al. 2023

An 83-year-old woman presented with a 1-year history of a growing mass on the lateral surface of the right knee. Magnetic resonance imaging revealed a large soft tissue tumor in the subcutis of the right knee. The mass in the right knee rapidly increased, due to hemorrhage from the tumor. A needle biopsy revealed that the diagnosis was synovial sarcoma. The patient underwent wide excision and lateral collateral ligament reconstruction using the plantaris tendon. The patient had a Musculoskeletal Tumor Society Score of 86% at the lateset follow-up. In conclusion, reconstruction of the lateral collateral ligament using the plantaris tendon may be useful for preserving the function of the knee joint after resection of the soft tissue due to sarcoma of the knee.

“…The PLT has excellent biomechanical properties, studies have shown that the mean maximal force of a single strand PLT is between 161 and 197 N 17,18 . More recently, we published a biome-chanical study of doubled PLT with a mean maximal force of 220.3 ± 108 N 19,20 . When compared with biomechanical properties of native ALL with a mean load to failure of about 180 N, the biomechanical properties of doubled PLT seem sufficient to replace it as a reconstruction graft [20][21][22] .…”

“…Magnetic resonance imaging (MRI) of the knee was mandatory for the confirmation of the ACL rupture and, in cases of revision surgery, the characteristics of prior femoral and tibial tunnels. Also, MRI was used to identify PLT, since PLT has an absence rate of 9% in the Croatian population 7,8 . Preoperatively, Lachman and Pivot shift tests were documented, and patients were assessed with KOOS score, IKDC evaluation form, Lysholm score and Tegner activity scale.…”

Anterior cruciate ligament (ACL) reconstructions with quadriceps tendon (QT) grafts are gaining popularity, both in primary and revision procedures. Recently, the role of the anterolateral ligament (ALL) of the knee in improving rotational knee stability has been emphasised and concurrent ACL and ALL reconstruction is advocated. In this paper, a new technique utilising the QT and the plantaris tendon (PLT) for combined ACL and ALL reconstruction is analysed. Patients that underwent combined ACL and ALL reconstruction using QT and PLT grafts in a 3-years period were prospectively analysed. A total of 9 patients with 6 months minimum follow-up were assessed with Lachman and Pivot shift clinical tests, International Knee Documentation Committee (IKDC) score, Knee injury and Osteoarthritis Outcome Score (KOOS), Lysholm score, and Tegner activity scale. One patient had reconstructed ACL re-rupture at the final follow-up visit, leaving 8 patients with a mean follow-up of 19±8 months. There was a significant improvement in anteroposterior and rotational stability in all the patients. The IKDC, KOOS, and Lysholm scores improved as well. The Tegner activity scale increased postoperatively, however, it did not reach preinjury values. QT and PLT grafts are valuable alternatives for currently used grafts in combined ACL and ALL reconstructive procedures. This new technique is a reasonable option in ACL revision surgery and a good alternative in primary ACL and ALL reconstruction, especially when hamstring grafts are not advised or they are missing.

“…20 Biomechanical experiments are required to obtain mechanical parameters for the FEM, and water loss can significantly affect tissue structure and mechanical properties. It is revealed that ligaments and tendons could be preserved at À20 C before biomechanical tests, 21 providing a reference for tissue preservation and subsequent mechanics experiments. In addition, the joint's kinematics state would affect the choice of material properties.…”

The knee is the most complex joint in the human body, including bony structures like the femur, tibia, fibula, and patella, and soft tissues like menisci, ligaments, muscles, and tendons. Complex anatomical structures of the knee joint make it difficult to conduct precise biomechanical research and explore the mechanism of movement and injury. The finite element model (FEM), as an important engineering analysis technique, has been widely used in many fields of bioengineering research. The FEM has advantages in the biomechanical analysis of objects with complex structures. Researchers can use this technology to construct a human knee joint model and perform biomechanical analysis on it. At the same time, finite element analysis can effectively evaluate variables such as stress, strain, displacement, and rotation, helping to predict injury mechanisms and optimize surgical techniques, which make up for the shortcomings of traditional biomechanics experimental research. However, few papers introduce what material properties should be selected for each anatomic structure of knee FEM to meet different research purposes. Based on previous finite element studies of the knee joint, this paper summarizes various modeling strategies and applications, serving as a reference for constructing knee joint models and research design.
