Objectives: Pilon fractures have a long-term negative impact on patients. Both initial cartilage damages (CDs) and osteoarthritis (OA) have been suggested to influence outcomes, but direct clinical evidence has been lacking. This study aims to investigate the association of initial CDs, OA occurrence, and functional outcomes. Methods: This is a prospective multicentre observational case series with a 2-year follow-up (FU). Initial CDs were evaluated intraoperatively in 116 enrolled patients; the postoperative OA was evaluated using FU radiographs. Functional outcomes were assessed using the Foot and Ankle Ability Measure (FAAM) for the activity of daily living (ADL) and sports activities (Sports). Change of FAAM scores over time was analyzed using mixed-effects model. Results: The 2-year loss-to-FU rate was 44.0%. Initial CDs on weight-bearing talus were statistically significantly associated with OA development (1-year, P < 0.001 and 2-year, P= 0.018) and poor functional outcomes (2-year ADL, P= 0.012 and 2-year Sports, P= 0.001). The existence of OA was statistically significantly associated with lower 1-year ADL scores (P = 0.018), 1-year Sports scores (P = 0.023), and 2-year Sports scores (P = 0.023). Patients with “good” reduction had higher outcome scores compared to patients with “satisfactory” reduction. Conclusions: In patients with well-reduced pilon fractures, initial CDs were associated with early/mid-term OA development and worse functional outcomes. OA occurrence was associated with worse functional outcomes. Current results need confirmation with a larger cohort.
