Randomised Double-Blind Placebo Controlled clinical trial to compare the efficacy of Adductor Canal Block versus Adductor canal block plus Intra-articular catheter for pain control following Total Knee Arthroplasty

HYPOTHESIS : Better pain relief and Range of Motion with Adductor Canal Block + Intra-articular catheter (ACB + IAC) than Adductor Canal Block alone

AIM :

*1.*To study the effectiveness of our Multimodal Pain control regime in pain management and early rehabilitation

2.To determine which of the following method provides effective pain relief and improvement in post-operative ROM

Group A: Adductor Canal Block + Intra-articular catheter (ACB +IAC)

Group B: Adductor Canal Block (ACB)

METHODOLOGY:

Sample size – 120 patients, each group 60 patients,

Group A: Adductor canal block + Intra-articular catheter group with anaesthetic drug,

Group B: Adductor canal Block + Intra-articular Catheter group with placebo  (normal saline)

Randomization will be done through random numbers generated according to software. Sealed envelope will be made. Patients will not be aware of the Group they are in.

Data analysis team will also be blinded from the study.

Data collection : VAS ( Visual Analog Score) to be collected at Post operative Day 0 and Day 1 every 8th hourly; Knee Range of motion will be collected at post operative Day 1.
