Abstract

Objective: To evaluate the surgical outcomes of patellar fracture treatment using Kirschner wire fixation combined with tension band wiring at Vo Truong Toan University Hospital from June 2021 to May 2024. Methods: A retrospective descriptive study was conducted on 30 patients with patellar fractures treated using Kirschner wire fixation and tension band wiring at Vo Truong Toan University Hospital from June 2021 to May 2024. Result: A total of 30 patients with patellar fractures were included, of whom 56.67% were male and 43.33% female. The majority belonged to the age groups 41–60 years (36.67%) and >60 years (33.33%). The most common cause of trauma was daily activities (50%), followed by traffic accidents (40%). Surgical fixation using Kirschner wires combined with tension band wiring showed favorable treatment outcomes. Radiographic bone union was achieved in 100% of cases from 2 months post-operation and maintained until 4 months, with no delayed union observed. The incidence of wound-related complications was low (6.67%), and no cases of wire migration or wire breakage were recorded; however, hardware irritation increased over time (0% at 2 weeks, 20% at 2 months, and 30% at 4 months). The degree of thigh muscle atrophy progressively increased (0.45 cm → 0.7 cm → 0.95 cm). Regarding functional outcomes, the rate of excellent recovery reached 73.33% after 4 months, and no cases were classified as “poor”.
