Summary: This study found that the need for medial ligament balancing during surgery was determined by constitutional alignment and preoperative mechanical parameters. Patients with constitutional varus and a larger change in medio-lateral gap difference in extension had a higher incidence of requiring medial ligament balancing.

Summary: Current ultrasound-guided punctures face challenges such as difficulty in operation, longer puncture times, lower success rates, and higher unexpected injury rates. This study aimed to verify the principle of needle tip detection and determine the optimal measurement conditions for vertical puncture. Through animal experiments and simulations, the principle of needle tip detection, effect of needle tip angle, and insertion depth on needle tip detection were confirmed.

Summary: The effect of ACL deficiency on lateral opening under varus stress was investigated in this study. It was found that ACL deficiency significantly increased lateral opening, regardless of the sequence of injury. When evaluating knee injuries, the effect of ACL injury on lateral structures should be considered.

Summary: Osteotomy combined with lateral ligament reconstruction is effective for treating osteochondral lesions in patients with talar injuries and varus ankles, leading to improved clinical outcomes and symptom relief. By correcting the force line on lower limbs and metapedes, these surgical treatments are critical factors in achieving better results for talar injuries.

Summary: This study aimed to investigate the effect of severe varus deformity on soft tissue balance in total knee arthroplasty (TKA). The results showed that the flexion and extension gap differences were significantly larger in the severe varus deformity group compared to the mild varus deformity group. The HKA varus angle was positively correlated with both gap differences and was an influencing factor for them.

Summary: This study evaluated the feasibility and efficacy of using the NGS system for operators of different experience levels in thyroid nodule targeting punctures. The results showed that NGS significantly improved the technical success rate and reduced the number of punctures for beginners with <50 cases of experience, as well as shortened the procedure time for operators with >=50 cases of experience.

Summary: The role of the lateral part of the distal triceps in improving stability in the lateral collateral ligament-deficient elbow and its relationship with the anconeus muscle is unclear. This study found that loading the lateral part of the distal triceps can prevent increased contact pressure on the coronoid and improve pressure distribution. Additionally, the anconeus muscle further decreases contact pressure and improves distribution, but its effect is independent of the lateral part of the distal triceps.

Summary: Fock and Goncharov introduce a family of cluster algebras associated with SLk-local systems on a marked surface. They study the algebraic and combinatorial properties of this family, focusing on the structures that arise when the surface has punctures. For k = 2, these structures correspond to tagged arcs and tagged triangulations. For higher k, the tagging of arcs is replaced by a Weyl group action at punctures. They also explore the higher analogue of tagged triangulations using tensor diagrams and develop skein-algebraic tools for calculating in these cluster algebras. They provide a detailed analysis of finite mutation type examples.

Summary: This systematic review examines the return to work status after total knee arthroplasty (TKA) and identifies physical nature of employment and preoperative work status as significant factors influencing the speed of return to work. While the majority of patients do return to work after surgery, comparisons between studies are hindered by variations in how work status is defined and measured. Standardized outcome measures for future studies on return to work after TKA are needed.

Summary: This study aimed to create a statistical shape model of the normal distal tibiofibular joint (DTFJ) with ligamentous morphometry, investigate the effect of weight-bearing on DTFJ alignment, and detect differences in syndesmotic ligament length between patients with syndesmotic ankle injuries and healthy controls. The results showed an increased tibiofibular diastasis in healthy ankles after weight-bearing and a significant difference in anterior syndesmotic ligament length between ankles with syndesmotic lesions and healthy controls.

Summary: Mechanical overload is the main cause of Achilles tendinopathy, and compressive loads may also contribute to the pathophysiology. However, data on intratendinous pressures is lacking. This study found that intratendinous pressure increased during stretching and eccentric loading, with the highest pressures in the deep insertion region and during the eccentric heel-drop. These findings suggest that compression plays a role in Achilles tendinopathy and further investigation is needed to explore its management in patients.

Summary: The study aims to assess the influence of medial or lateral imaging plane inclination on the measurement of sulcus angle, trochlear depth, and facet asymmetry on transverse cross-sectional images. The results show that an 8-degree medial or lateral inclination does not significantly affect the typical parameters used for the assessment of trochlear dysplasia, but the measurement height has a significant impact.

Summary: The study evaluated the effects of muscle load on knee kinematics and stability after total knee arthroplasty (TKA), as well as the effect of TKA surgery on knee kinematics and stability. It also examined the correlation between stability in passive conditions and stability in active, muscle loaded conditions. The results showed that muscle force led to increased valgus and internal rotation of the femur, while TKA surgery resulted in more varus and external rotation. Muscle load and TKA implantation significantly reduced all laxities. The presence of the implant had a significant impact on active varus/valgus laxity, while passive laxity was the main determinant for rotational laxity. Passive laxity was also a significant predictor of active laxity for varus/valgus. In conclusion, knee stability is affected by muscle load, highlighting the importance of appropriate rehabilitation to prevent muscle atrophy. The functional, muscle loaded stability is strongly related to passive, ligament-based stability. Therefore, it is crucial to assess knee stability at the time of surgery, as passive laxity is the only predictor for functional stability in the operating theatre.
