Background: Calf muscle strain injuries (CMSI), also known as "tennis leg," are frequently observed in middle-aged and physically active people, including non-professional athletes. While magnetic resonance imaging (MRI) is frequently used to assess the extent of these injuries, the relationship between MRI findings and long-term functional outcomes in non-athletic populations remains underexplored. This study aimed to investigate the correlation between MRI-detected injury severity and functional outcomes using the Achilles Tendon Rupture Score (ATRS) and the Tegner Activity Scale (TAS).

- - *The study analyzed the relationship between body measurements and the thickness of peroneus longus tendon grafts, using ultrasound imaging on 204 healthy volunteers aged 18-40.* - *Results showed that males generally had thicker grafts compared to females, and various measurements such as height, weight, and calf circumference were identified as indicators of sufficient graft thickness.* - *The findings suggest that calf circumference and activity level are particularly important predictors of graft thickness in both genders, with specific cutoff points established for effective assessments in clinical settings.*
Article Synopsis
- * Patients were divided into two groups: one receiving patellar denervation (PD) and the other without (NPD), and outcomes like knee pain and function were measured before and after the surgery.
- * There were no significant differences in pain and functional scores between the two groups, but both showed improvement over time, with scores indicating better outcomes at 3 and 6 months post-surgery.

July 2024
Article Synopsis
- - The study evaluated how different fluoroscopic settings affect the accuracy of finding Schottle's point during medial patellofemoral ligament (MPFL) reconstruction, using 44 dry femurs.
- - Results showed that the lateral-to-medial (LM) view significantly reduced the distance from the anatomical MPFL footprint to Schottle's point compared to the medial-to-lateral (ML) view, resulting in a higher percentage of acceptable tunnel locations.
- - The findings suggest that using the LM fluoroscopic view can enhance the accuracy of femoral tunnel placement, leading to better surgical outcomes by more accurately replicating the native MPFL.
Article Synopsis
- This study evaluates the long-term effects of saphenous nerve (SN) injuries resulting from hamstring tendon harvesting during ACL reconstruction, focusing on clinical results and patient satisfaction over two years.
- A retrospective review of 159 patients showed that 54.7% experienced SN injuries right after surgery, with some still having issues at the final follow-up.
- Persistent injuries significantly affected patients' daily activities and functional outcomes, with a notable correlation between these injuries and higher ACL re-rupture rates.

Handchir Mikrochir Plast Chir
September 2024
Article Synopsis
- The study investigated if simple body measurements (height, weight, forearm length, and wrist circumference) could predict the length and thickness of the palmaris longus tendon (PLT) in 120 healthy volunteers.
- Results showed that while there was a moderate correlation between body height and PLT length, and a weak correlation between forearm length and PLT thickness, the predictive power was limited.
- The research concluded that, although height and forearm length could provide some predictions, ultrasonographic examination remains crucial for determining PLT dimensions needed for surgical grafts.

Article Synopsis
- The study aimed to compare the volume and weight of bone grafts harvested from the anterior iliac crest using two different techniques: trephination and curettage.
- Ten embalmed adult cadavers were used, with one side harvested using trephination and the other using curettage, and measurements of weight and volume were statistically analyzed.
- Results showed that the trephination technique yielded significantly heavier and larger bone grafts and was quicker than the curettage technique, suggesting it may be the preferred method for obtaining larger autologous bone grafts, while emphasizing the importance of careful technique to avoid complications.

Article Synopsis
- ! A finite element analysis was conducted to evaluate the biomechanical properties of four different screw configurations used for fixing the Fulkerson osteotomy in patients with patellofemoral instability. * ! The configurations explored included variations in the alignment of two 4.5 mm cortical screws relative to the osteotomy plane and posterior tibial cortex, with their performance assessed based on gap formation, displacement, and frictional stress. * ! Results indicated that the screw configuration where the upper screw was perpendicular to the osteotomy plane and the lower screw to the posterior cortex showed the least displacement (0.245 mm) and the most effective resistance against displacement during loading, while the configuration where both screws were perpendicular to the osteotomy plane had the highest frictional

This finite element analysis aimed to compare the mechanical behaviour of different fixation techniques in tibial tubercle antero-medialisation osteotomy combined with distalisation procedure.
Methods: Tibial tubercle osteotomy combined with distalisation was modelled based on computerised tomography data, which were acquired from a patient with patellar instability requiring this procedure.
Malleolar screw fixation is the most widely used treatment method for medial malleolar (MM) fractures. Here, although buttress plate fixation is advocated for vertical MM fractures, the angular discrimination between oblique and vertical MM fractures is still not fully understood. The purpose of this study is to test the adequacy of screw fixation in MM fractures with different angles and determination of a 'critical fracture angle' to guide surgeons in the decision-making for screw fixation for MM fractures by utilizing an advanced engineering simulation approach.
