Abstract
Introduction The objective of this case series is to evaluate the clinical outcome of patients with tibial shaft fractures treated by suprapatellar nailing at a 2-year follow-up and to review available literature concerning this approach. Method and material This is a retrospective single-centre case series to evaluate patients' post-operative status at 2-year intervals. Fifteen (15) patients underwent intramedullary nailing with a supra-patella approach during the year 2019–2020 and consented to participate in this case series. Patients were regularly followed up in the outpatient clinic and evaluated in terms of range of movement, walking status and radiologically with RUST score and tibia alignment. Their functional outcome was assessed by a questionnaire including OKS, VAS, and Kujula scores. Results At post-op 2 years intervals, all patients had radiologically healed fractures as evidenced by RUST score and tibia alignment within five degrees in the coronal and sagittal plane, the functional outcome of the suprapatellar approach was satisfactory in the visual analogue scale and various knee scores. All patients achieved a full range of movement and could walk unaided. Discussion Technical tricks and tips for the suprapatellar approach are discussed. Literature review showed satisfactory outcomes for intramedullary nailing for tibial shaft fracture in different parts of the world. Compared with the infra-patellar approach, the suprapatellar approach is superior in fracture alignment but has no significant difference in terms of pain, disability and range of movement. Potential risk of suprapatellar approach is discussed including possible cartilage damage and intra-articular sepsis. Conclusion There is a good clinical outcome of the suprapatellar approach to tibial nail radiologically and functionally. Results are in line with the literature review, which also showed that compared with the infra-patellar approach, the suprapatellar approach is associated with better alignment and less knee pain but no significant difference in range of movement and disability.
