Due to its high sensitivity in diagnosing small bleeds, MRI offers a well-documented evaluation of primary acute TBIs.

Balancing Anterior and Posterior Cruciate Ligaments in Adults.

Background: The anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) represent the central pivot of the knee. The balance between these two ligaments impacts the tibiofemoral biomechanics. Each structure is the opposite of the other in terms of anteroposterior translation and rotation.

Tibia-first, gap-balanced patient-specific alignment restores bony phenotypes and joint line obliquity in a great majority of varus and straight knees and normalises valgus and severe varus deformities.

Purpose: The present study focuses on testing the capability of a restricted tibia-first, gap-balanced patient-specific alignment technique (PSA) to restore bony morphology and phenotypes.

Methods: Three-hundred and sixty-seven patients were treated with navigated total knee arthroplasty and tibia-first gap-balanced PSA technique. Boundaries for medial proximal tibial angle were 86°-92°, mechanical lateral distal femoral angle 86°-92°, and hip-knee-ankle angle 175°-183°.

Gender-based differences exist in the functional knee phenotypes classification of the osteoarthritic knee.

Purpose: To identify gender differences in (1) the coronal alignment of functional knee phenotypes and (2) the JLCA (joint line convergence angle) in relation to the phenotype classification.

Methods: This study is a retrospective data analysis, including 12,099 osteoarthritic knee computed tomography (5025 male, 7074 female) analysed by Medacta software for hip-knee-ankle angle (HKA), femoral mechanical angle (FMA), tibial mechanical angle (TMA) and JLCA. The data were grouped into genders and combined according to the Functional Knee Phenotypes Classification.

Long head of the biceps tendon versatility in reconstructive shoulder surgery: a narrative review of arthroscopic techniques and their biomechanical principles with video presentation.

The management of the long head of the biceps tendon (LHBT) during shoulder arthroscopy has been a subject of controversy for many years, with evolving discussions and trends. Despite long-standing debate, the nature of the surgical indication regarding how to treat concomitent LHBT injuries has undergone changes in recent years. It now extends beyond the timing of tenotomy to encompass considerations of alternative methods for preserving the LHBT, along with an ongoing exploration of how it can be effectively utilized in reconstructive shoulder surgery.

Dynamic Anterior Stabilization with Hill-Sachs Remplissage Can be Employed in Skeletally Immature Patients-Operative Technique.

Background: Numerous studies indicate that glenoid bony augmentation raises the risk of complications during and after surgery. On the other hand, repairing the labrum alone in cases with subcritical glenoid bone loss results in recurrent instability and persistent apprehension. As a result, recent advancements in shoulder instability surgery prioritize fully restoring the anterior shoulder restraint.

Partial Articular Supraspinatus Tendon Avulsion Repair and Patch: A Technical Note for Augmenting the Supraspinatus Reinsertion with the Long Head of the Biceps Tendon.

Background: There is no clear consensus on the treatment of partial articular-sided supraspinatus tendon avulsions. Debridement alone might not be sufficient to prevent further tendon degradation or alleviate patient complaints. Direct repair using a suture anchor without treating the concomitant conditions of the long head of the biceps tendon might come with residual anterior shoulder pain or even further loss of function in cases of failed repair.

Acetabular cup placement and offset control in robotic total hip arthroplasty performed through the modified anterolateral approach.

Purpose: The modified anterolateral approach (Röttinger) for total hip arthroplasty (THA) offers great advantages over conventional approaches, especially concerning early postoperative symptoms, which are mild and well tolerated by patients. Robotic-assisted implantation might facilitate rapid adoption of the modified anterolateral approach without exposing surgeons to risks encountered during the learning curve. This study posits that the use of robotic assistance in conjunction with the modified anterolateral approach for total hip arthroplasty (THA) can provide a substantial enhancement in the accuracy of cup placement in comparison to manual surgery.
