Summary: Noninvasive estimation of joint loads is still a challenging task in biomechanics. Despite the use of musculoskeletal modeling, improvements are needed to obtain accurate predictions of joint loads. This study reviewed the state-of-the-art literature on the estimation of hip joint reaction forces and found that predicted hip joint loads still deviate from experimental measurements and tend to overestimate them. Critical factors affecting muscle force estimation and joint loads include the physical fidelity of the musculoskeletal model and the chosen muscle recruitment strategy.

Summary: The study found that Nordic walking has a similar impact on hip joint loads as regular walking, making it a low-impact activity suitable for patients allowed full weight bearing, such as during postoperative rehabilitation after total hip arthroplasty.

Summary: Footwear choice post joint replacement surgery plays a crucial role in affecting hip joint loads during physiotherapy. This study examined the impact of different types of shoes on in vivo hip joint loads, finding that shoes, especially those with stiff soles or elaborate cushioning elements, tend to increase hip joint loading during walking. Preferably, low-profile shoes with a flexible sole may be more suitable for patients aiming for reduced hip joint loads, especially during postoperative physiotherapy or to alleviate osteoarthritis symptoms.

Summary: This study modified an existing musculoskeletal model to simulate hip joint motion and validated it against experimental data. The results showed that the modified model accurately estimated hip contact forces and muscle activations in response to various dynamic tasks among young adults. The differences in hip contact forces and muscle activations between young adults and previously studied patients may be attributed to different movement patterns.

Summary: This study compared hip joint forces between people with FAIS and healthy controls during squat tasks, as well as within limbs during single leg squat tasks in people with FAIS. The results showed that patients with FAIS had lower hip joint forces compared to controls and the uninvolved side during single leg squat tasks. This reduction in joint forces may be a strategy to avoid pain and symptoms during these demanding tasks.

Summary: Musculoskeletal models are crucial for biomechanical investigations, but deformable contact models of the hip are often overlooked. This study presents a new approach using finite element analysis to simulate hip joint movement within a musculoskeletal model, providing insights into hip contact mechanics.

Summary: Femoral torsion is related to hip kinematics, kinetics, hip contact forces, and muscle forces during gait, with higher femoral antetorsion leading to significantly higher anteromedial HCFs. The majority of loads during gait are transmitted through the anterior/superolateral quadrant of the acetabulum, with correlations observed with hip kinematics and muscle forces.

Summary: This study constructs a comprehensive simulation method for analyzing the dynamics and contact stress changes of the hip joint throughout a gait cycle. Individualized simulation modeling is achieved based on gait trajectories and CT images. The combination of subject-specific gait and inverse dynamic analysis provides pre-processing parameters for more accurate biomechanical analysis of the hip joint.

Summary: Knee arthrodesis has a negative influence on the neighboring hip and ankle joints during walking, resulting in reduced forefoot repulsion, restricted movement on the operated side, and reduced movement in the ankle/knee joint.

Summary: This study proposes a full inertial-capture-based musculoskeletal modelling workflow for estimating joint contact forces. The results show that the proposed method can accurately estimate knee contact forces compared to motion capture, which is important for monitoring knee joint loading and assessing therapeutic effects in clinical practice.

Summary: Anatomical parameters significantly affect knee contact forces, with contact point variations leading to more marked changes. The distribution of medial-lateral forces varies depending on the motor activity, with stair negotiation resulting in increased lateral forces.

Summary: This study investigates the biomechanical changes in the knee joint during walking caused by medial meniscal radial tears associated with knee osteoarthritis (OA). The results show that larger medial meniscal radial tears are prone to high stress concentrations and an increased risk of complete meniscal rupture. Furthermore, the tears disrupt the stress-transmitting function of the meniscus, greatly increasing the likelihood of developing knee OA. Complete postmeniscectomy also leads to a significant increase in tibial cartilage load, indicating a potential risk of OA flare-ups.

Summary: An accurate and reliable radiological assessment of lower limb alignment in children and adolescents is crucial for treatment decision-making and post-operative follow-up. This study found good to excellent intra- and interobserver reliability for most measurements, and the standard error of measurement for femoral and tibial lengths was ±4.53 mm and ±3.12 mm, respectively.

Summary: The mechanical load distribution during bipedal stance is unbalanced in patients with unilateral hip osteoarthritis, but can be improved after total hip replacement. It is important to note that, similar to walking, load distribution during stance is also asymmetric, highlighting the need for preventive therapy concepts to optimize load distribution in both legs.

Summary: This study investigates the mechanical influence of tension-band plates on the growth plate using personalized finite element models. The results show that the implant induces static stress and reduces cyclic loading and unloading in the insertion region, leading to a decrease in growth rate. On the contralateral side of the growth plate, increased tension stress is observed, promoting growth.

Summary: The correction of valgus leg malalignment in children using implant-mediated growth guidance is widely used and effective. However, a relevant number of patients may experience prolonged pain and limited mobility after the procedure. This study aimed to investigate the risk factors associated with implants, surgery, and anesthesia, as well as the impact of tourniquet pressure and surgery duration on these complications.

Summary: The accuracy of final adult height predictions using the CPH method was evaluated in this study. All predictions overestimated the final adult height, with the SGP multiplier table yielding the lowest overestimation. There were no significant differences in accuracy between using skeletal age and chronological age when using the PHV or SGP multiplier tables. Predictions based on chronological age showed higher correlations with the final adult height compared to predictions based on skeletal age.
