Summary: This study aimed to investigate the relationship between lower limb alignment and soft tissue balance after total knee arthroplasty (TKA). The results showed that the relaxation of soft tissues around the knee joint changed over time after TKA, but this change did not significantly affect the alignment of the lower limbs.

Summary: This study compared the clinical effects of the bridge combined fixation system (BCFS) and locking plate (LP) in the treatment of refractures around implants in geriatric patients following proximal femoral fracture surgery. The results showed that BCFS had advantages such as minimal surgical trauma, promotion of fracture healing, and early functional rehabilitation.

Summary: This study demonstrated that varus/valgus deformity of the femur has a significant impact on the contact area and stress distribution of the knee joint, providing biomechanical evidence for orthopedic trauma surgery or surgical correction of existing varus/valgus deformities.

Summary: The study developed a whole-joint, unidimensional, irreversible, and fine-grained MRI knee osteoarthritis (OA) severity score, OA-COM, which reflects cartilage, osteophytes and menisci. OA-COM scores of 12, 18, 24 and 30 are equivalent to KL grades 1 to 4, offering fine-grained differentiation between KL grades and within pre-radiographic disease (KL=0) or late-stage disease (KL=4). Several clinical variables predicted progression across different states over 7 years.

Summary: This retrospective study compares two patient groups with different severities of injuries in geriatric traumatology, identifying age, known dementia, pre-clinical intubation, and the lowest Hb value as significant influencing factors for functionality upon discharge. Despite their old age and vulnerability, the majority of geriatric patients survive accidents, highlighting the need for further investigations on functionality maintenance or restoration post-accident.

Summary: This review discusses the outcomes of bilateral knee arthroplasty in patients with windswept deformity (WSD). The results show that knee replacement surgery improves knee function and reduces axial deviation in both valgus and varus knees. Unicompartmental knee arthroplasty (UKA) allows for limited axial correction, while kinematic alignment (KA) provides similar results in both knees. The choice of implant is important for functional outcomes.

Summary: Varus-valgus lower alignment affects the contact area of the patellofemoral joint. Magnetic resonance imaging can be used to measure the contact area of the patellofemoral joint.

Summary: The study aimed to evaluate functional outcomes in patients with varus malposition following open reduction and internal fixation of displaced proximal humeral fractures. The results suggested that varus malposition is associated with inferior functional outcomes compared to anatomic healing, supporting the recommendation to prevent varus malposition in the treatment and consider revision surgery in severe cases.

Summary: Mechanical loading plays a significant role in bone fracture healing. The loading on lower limb long bones varies with knee flexion angle and frontal knee alignment during walking. Different load components were observed in the femur and tibia, which indicates the need for adapted fracture fixation based on load components rather than overall load level.

Summary: The study compared the performance of the Distal Tibia Nail (DTN) and Medial Distal Tibia Plate (MDTP) in supramalleolar corrective osteotomies. Results showed that DTN had higher compressive stiffness in the best-case surgical scenario, while MDTP performed better in the worst-case scenario.

Summary: The study demonstrated that the TSIN exhibited better stability and stress conduction compared to PFNA. TSIN enhanced stability in intertrochanteric fractures, particularly in superior fracture fragments, improved stress conduction, reduced stress in the anterior and medial femur, and restored the biomechanical properties of the femur.

Summary: Less than one-third of patients (28%) with varus alignment have a tibial deformity. Only 12% of patients can be corrected via isolated high tibial osteotomy for anatomic correction, while 63% require a double-level osteotomy.

Summary: This study found that implant failure is common in small animal orthopedics and is associated with abnormal fracture healing. Among the cases studied, 23% experienced implant failure, which was significantly associated with delayed union, malunion, or non-union.

Summary: This study analyzed the mechanical stability of different fixation constructs for basicervical fractures using finite element analysis. The results showed that the DHS + screw construct had the optimal load distribution, and the FNS implant was suitable for anatomically reduced fractures without comminution.
