Methods: A prospective comparative analysis was performed comparing consecutive female and male patients having been treated by the press-fit TOPIC procedure. Clinical comparative assessment preoperatively and at 12 months of follow-up included determination of the Numeric Rating Scale (NRS) scores for pain during walking (primary outcome), at rest and during stair-climbing.

Automation improves the efficiency of weightbearing CT scan 3D volumetric assessments of the syndesmosis.

Background: Weight-bearing CT (WBCT) 3D volumetric measurement has shown promising accuracy for the diagnosis of syndesmotic instability. However, these measurements are rather complex and time-consuming, rendering them a clinically unfavorable option. We hypothesized that automatized measurements would be more accurate and time-efficient than manual ones.

The deltoid ligament is constantly formed by four fascicles reaching the navicular, spring ligament complex, calcaneus and talus.

Purpose: The medial collateral ligament of the ankle, or deltoid ligament, can be injured in up to 40% of patients who sustain an ankle inversion sprain. Reporting injuries of the deltoid ligament is not easy due to confusion in the current anatomical descriptions, with up to 16 fascicles described, with variable frequencies. The purpose of this study was to clarify the anatomy of the deltoid ligament.

Wide-Awake Needle Arthroscopy of the Anterior Ankle: A Standardized Approach.

Over the years, possibilities in ankle arthroscopy have evolved from diagnostic inspection to complex interventional procedures. Further innovation may come from needle arthroscopy, which has improved substantially in image quality in recent years and can now be used for interventional procedures as well. We here present a standardized approach to wide-awake needle arthroscopy of the anterior ankle under local anesthesia.

Fixation of Osteochondral Lesions of the Talus: Indications, Techniques, Outcomes, and Pearls from the Amsterdam Perspective.

The treatment of osteochondral lesions of the talus (OLT) remains a topic of debate as no superior treatment has yet been identified. The current consensus is that it is crucial to incorporate lesion and patient characteristics into the treatment algorithm. One such lesion type is the OLT with a fragment, which may benefit from in situ fixation.

Enhancing precision in osteochondral lesions of the talus measurements and improving agreement in surgical decision-making using weight-bearing computed tomography and distance mapping.

Purpose: Weight-bearing computed tomography (WBCT) enables the creation of a three-dimensional (3D) model that represents the ankle morphology in a standing position. Distance mapping (DM) is a complementary feature that uses color coding to represent the relative intraarticular distance and can be used to outline intraarticular defects. Consequently, DM offers a novel approach to delineating osteochondral lesions of the talus (OLT), allowing for the quantification of its surface, volume and depth.

Implantation of a Cushioning Injectable Implant Using Needle Arthroscopy in the Foot and Ankle and First Carpometacarpal Joint.

Injectable implants constitute a newly developed treatment class in the battle against osteoarthritis. They consist of water-formulated supramolecular polymer, coming from a new class of resorbable biomedical materials, and are implanted in encapsulated joints in a liquid form, where they solidify to form a tough, elastic, and cushioning layer between the joint surfaces. To resort any effect, intra-articular delivery should be guaranteed, and the implant should be distributed throughout the entire joint space.
