Relationship Between Ankle Ligamentous Injuries and Osteochondral Lesions in a Saudi Arabian Population: A...

Objectives This study aimed to investigate the relationship between ankle ligamentous injuries and osteochondral defects (OCDs) and to determine the incidence of these conditions within the Saudi Arabian population. Methods This retrospective cohort study included 215 patients (110 males and 105 females) who sought medical advice for an ankle injury at our institute from January 2017 to August 2022. The patients were divided according to age, sex, presence and type of ligamentous injury, and status of OCDs. Patients' ages were categorized into three groups: younger than 30 years (48 patients), 30-60 years (145 patients), and older than 60 years (22 patients). The patients were assessed for ligamentous ankle sprains, tears, and OCDs by reviewing their magnetic resonance imaging reports from radiology records. The exclusion criteria included ankle fracture, ankle surgery, osteoarthritis of the ankle joint, inflammatory arthritis, and congenital deformity of the ankle. The data were collected using a simple questionnaire created via Google Forms. Results Of the 24 patients with OCD, 23 had OCD of the talus. Anterior talofibular ligament (ATFL) injury was the most common injury (75 patients), whereas posterior talofibular ligament (PTFL) injury was the least common. The only significant relationship between ligamentous injury and OCD was observed between PTFL injury and OCD of the talus (P = 0.041). Conclusions In patients with an ankle injury, the most common OCDs occur at the talus, whereas the most injured ligament is the ATFL. Nevertheless, a significant relationship was observed between PTFL injury and OCD of the talus. The findings underscore the importance of considering specific ligament injuries when diagnosing and managing OCDs, especially in patients with chronic ankle pain.
