Article Synopsis
- The study aimed to compare the image quality and visibility of lesions in zero echo time (ZTE) MRI using a deep learning (DL) algorithm against conventional reconstruction methods, and to evaluate DL ZTE's effectiveness in assessing bone loss for shoulder instability compared to CT scans.
- Forty-four patients with shoulder instability underwent both ZTE MRI and CT scans, with images evaluated by two radiologists for clarity, resolution, and how well they showed lesions, using a rating scale.
- Results indicated that DL ZTE MRI images had superior resolution and showed lesions more clearly than conventional methods, with excellent agreement between DL ZTE and CT scans for measuring bone parameters.
Hill-Sachs lesions (HSLs) can be present after a primary shoulder dislocation and may go unrecognized; this can alter the necessary bony constraint within the glenohumeral joint. To deal with HSLs, remplissage is a safe procedure with low complication rates, low recurrent instability rates, and good patient outcome scores compared with many of the other alternative techniques. On the other hand, a great number of techniques have been described to treat reverse Hill-Sachs lesions (RHSLs).

The "FineGrain" research tool (FineGrain RT) uses a continuous stimulation paradigm combined with automatic ECAP threshold determination. The aim of this study was to compare the FineGrain RT with standard ART.

Design: Twenty-four consecutive patients with International Cartilage repair Society (ICRS) grade 3-4 cartilage lesions of the ankle were included. Five million chondrocytes per cm of lesion were implanted using a type I/III collagen membrane as a carrier and treatment effectiveness was assessed by evaluating pain with the visual analogue scale (VAS) and American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score at baseline, 12-month, and 24-month follow-up, together with dorsal and plantar flexion.
Objective: The aim of this work was to study the short- and mid-term effectiveness and safety of high-density autologous chondrocyte implantation (HD-ACI) in the first 50 patients with knee cartilage damage treated in our unit.
Design: Fifty consecutive patients with cartilage lesions (Outerbridge grade III-IV) in the knee treated with HD-ACI were included in this study. Chondrocytes were isolated from a nonbearing cartilage area biopsy and were cultured until 40 to 50 million cells were obtained.
