    Abstract: <p style="text-align:justify">Total knee arthroplasty (TKA) or total knee replacement (TKR) is a common orthopedic procedure and is the gold standard treatment for patients with end-stage knee osteoarthritis who have not responded to other treatments. Present study was aimed to study femoral nerve block versus adductor canal block for analgesia after total knee arthroplasty. Present study was prospective, comparative study, conducted in patients of age group 50-70 years, either gender, ASA physical status class I, II and III patients, posted for unilateral TKA. In present study, 60 patients were randomly allocated into group A (n = 30, received adductor canal block) and group B (n = 30, received femoral nerve block). Group A and B had comparable quadriceps muscle strength measured by MRC grading at 6 hrs (1.91&plusmn;0.68 vs. 1.89&plusmn;0.59) and no statistically significant difference was noted. Group A had better quadriceps muscle strength than group B at 12 hrs (2.88&plusmn;0.45 vs. 2.13&plusmn;0.64) and at 24 hrs (3.34&plusmn;0.67 vs. 2.65&plusmn;0.81), difference was statistically significant (p&lt;0.001). Post-operative analgesia measured by VAS scores at baseline (3.7&plusmn;1.1 vs. 3.6&plusmn;0.9), after giving the ultrasound guided block at 6 hrs (2.7&plusmn;0.8 vs. 2.6&plusmn;0.9), 12 hrs (2.5&plusmn;0.6 vs. 2.4&plusmn;0.7) and 24 hrs (2.2&plusmn;0.7 vs. 2.3&plusmn;0.6) were comparable between both groups and no statistically significant difference was noted among them. Adductor canal block (ACB) preserved quadriceps muscle strength better than femoral nerve block (FNB), without a significant difference in postoperative analgesia after total knee arthroplasty surgeries.</p>
