Article Synopsis
- This study examines the effectiveness of weight-bearing computed tomography (WBCT) in evaluating total ankle arthroplasty (TAA), addressing limitations of traditional imaging techniques like rotational bias and bone overlap.
- Researchers created and analyzed preoperative and postoperative 3D WBCT models for 81 patients, measuring various angles to assess changes in ankle alignment after surgery.
- Results showed significant improvements in specific angles, indicating the reliability of WBCT for accurate TAA assessment, with inter-rater and intra-rater reliability scores demonstrating strong consistency.
Background: While weightbearing computed tomography (WBCT) has been instrumental in analyzing total ankle arthroplasty (TAA) positioning, there is a notable gap in the literature regarding adaptive changes in the foot's medial column after TAA. This study aims to bridge this gap by comparing preoperative and postoperative alignments of the foot's medial column and analyzing if a correlation exists between TAA coronal alignment correction and medial column alignment adaptation.
Methods: Sixty patients who underwent a lateral approach TAA for end-stage osteoarthritis (OA) between January 2021 and April 2023 were included in this retrospective study.
Osteochondral lesions of the talus (OLTs) are the most common cause of chronic deep ankle pain. Joint-preserving surgeries include bone marrow stimulating, chondral transporting, and cellular-based procedures. Each procedure has its advantages and disadvantages.

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.

The secondary aim was to assess whether age, body mass index (BMI), and lesion surface affect outcomes.
Design: Sixty-three patients (32 males, 31 females) with a median age of 37 years [interquartile range (IQR): 25-48] were included.
