Post-operative pain management using local infiltration analgesia (LIA) in total knee arthroplasty (TKA): A prospective study

Abstract

Objectives: Post-operative pain management in Total Knee Arthroplasty (TKA) remains a challenging issue even though it is a commonly performed procedure today. Majority of the patients report severe pain following surgery due to which mobilization and early rehabilitation is hampered. Therefore, appropriate pain management is the need of the hour and Local Infiltration Analgesia (LIA) using periarticular cocktail injection is one of the preferred techniques. The objective of this study was to assess the functional outcome and patient satisfaction after using LIA in the form of periarticular Ranawat-cocktail among post-TKA patients.Materials and Methods: This study was conducted at SGITO, Bangalore during the period between August 2017 to April 2018. In this study, we used LIA consisting of the Ranawat Regimen for TKA patients which contains (bupivacaine with adrenaline, morphine, methylprednisolone, cefazoline and normal saline) to manage postoperative pain in all 53 patients presenting to our institute for primary TKA. Functional outcome was assessed in terms of post-op VAS score, ROM, and SLRT at 12hrs, 24hrs, and 48hrs post-op. Opioid consumption, and patient satisfaction was recorded and statistical analysis was done.Results: The mean age of patients in the study was 60.83. Mean VAS pain score at 12hrs, 24hrs, and 48hrs post-op were found to be 5, 3.5 and 2.79 respectively which indicated a highly significant (p
