Comparison of Medial Parapatellar and Transpatellar Tendon Approach in Intramedullary Interlocking Nailing for Tibial Fracture: A Retrospective Analysis

Abstract

Introduction Tibial fractures are one of the most common traumatic fractures, particularly in automobile accidents. Percutaneous reduction with conventional reduction forceps and un reamed intramedullary nailing, transpatellar, and medial parapatellar tendon approaches are all used, but tibial intramedullary nails are still primarily inserted through a transpatellar tendon splitting or medial parapatellar tendon approach. Objective The aim and objectives of this study are to assess the mean pain score after nailing for a tibial fracture using a medial parapatellar versus a transpatellar tendon method retrospectively in order to enhance operational planning. Materials and methods This is a retrospective study that took place in a UK level 1 trauma center. Data from 60 patients were included between February 2019 and February 2020. An equal number of patients were selected for both approaches to maintain accuracy. The advanced trauma life support (ATLS) protocol was used to handle all of the patients in both groups in order to rule out any other injuries or fractures, after which they were scheduled for surgery after stabilization. They were subsequently evaluated during a three-month follow-up in an outdoor clinic, where they were given a pain score using the visual analogue score (VAS) while moving their knee joints. The mean pain score was differentiated by age, gender, body mass index (BMI), injury side, and injury type. Results Patients were divided into groups based on their ages. Patients in the transpatellar tendon group were 32.83±5.13 years old, whereas those in the medial parapatellar tendon group were 31.4 ±5.42 years old. The gender distribution of the patients revealed that the majority of the patients in both groups were male. In both groups, the left side was the most usually affected. The difference between the two groups' mean pain scores at three months was substantially lower in the medial parapatellar approach (p=0.005). Conclusion For patients having intramedullary nailing for tibial fractures, the medial parapatellar route is associated with a lower mean pain score than the transpatellar route. As a result, we may use this method in these individuals regularly.
