Arthroscopically Assisted Technique in the Treatment of Ankle Fractures with Posterior Malleolus Fragment in Adults

Abstract

Abstract Introduction: Ankle fractures constitute a challenging condition due to its high impact on the long term. Thus, advancements in management have been proposed to ensure the best possible outcome. Hence, we aimed to assess the role of arthroscopy in the treatment of ankle fractures that involve posterior malleolus fragments in adults. Patients and Methods: In a quasi-experimental, interventional, prospective, nonrandomized study, we included 16 adult patients with acute ankle fracture with posterior malleolus fragment. They underwent arthroscopically assisted technique for their fracture treatment. A standard systematic arthroscopic ankle examination, their fracture grade, and classification were assessed, and subsequent management was conducted. The patients were followed up for 6 months using the American Orthopedic Foot and Ankle Society (AOFAS) score and radiographic monitoring with standard X-ray. Results: The mean AOFAS score improved significantly after 6 months of follow-up (from 84.81 in the 3 rd month to 92.81 in the 6 th month). Ankle dorsiflexion angle and ankle plantar-flexion angle showed a gradual increase during follow-up, reaching 17.31° ± 3.25° and 45° ± 5°, respectively. Only two patients developed complications. Age, body mass index, and grade of the osteochondral lesion were negatively correlated statistically significantly with the AOFAS score. This proves the effective role of arthroscopically assisted technique in the treatment of ankle fractures with posterior malleolus fragment. Conclusion: Arthroscopically assisted technique in the treatment of ankle fractures with posterior malleolus fragment in adults resulted in good functional outcomes with less complications and it allows the assessment of associated intra-articular injuries. Further studies with longer follow-up periods are needed for the assessment of outcomes and complications for comparison.
