Abstract :Background: Patella fractures account for about 1% of skeletal injuries, leading to pain, limited knee motion, extensor weakness, and difficulty with weight-bearing. This study retrospectively assessed clinical and radiological outcomes of patients with OTA/AO Type 34-C patella fractures treated with tension band wiring, analyzing fracture type and treatment outcomes in relation to daily activities to identify potential correlations. Methods: Between 2017 and 2024, 28 patients treated for OTA/AO Type 34-C fractures with tension band wiring and attending regular follow-ups were included. Data on age, gender, ASA score, AO fracture type, and fracture side were collected. At six months postoperatively, KOOS, VAS, and knee range of motion (ROM) were assessed. Results: The 28 participants had an average age of 45 ± 19.65 years. No significant differences were found between males and females in ROM, KOOS scores, or VAS (p > 0.05). AO34-C3 fractures were the most common. AO Type C1 fractures had the highest KOOS scores and lowest VAS pain scores, while AO34-C3 fractures had the lowest KOOS scores and highest VAS scores. However, no significant differences were found in ROM, KOOS, or VAS scores across OTA/AO fracture subtypes (C1, C2, C3) or fracture side (p > 0.05). Conclusion: This study highlights that while literature reports poor medium- and long-term outcomes for comminuted, displaced patella fractures, the early period differences in outcomes between subtypes, though not statistically significant, suggest other contributing factors. The prevalence of OTA/AO Type C3 fractures emphasizes the need for tailored treatment protocols for this subtype.
