Patients were randomly assigned to either the LB group or the \"cocktail\" group in a 1∶1 ratio using a random number table, with 40 patients in each group. Baseline characteristics, including gender, age, body mass index, operated side, Kellgren-Lawrence grade, and preoperative American Society of Anesthesiologists (ASA) classification, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and knee joint range of motion, showed no significant difference between the two groups ( &lt;i&gt;P&lt;/i&gt;&gt;0.05). Both groups received LIA and comprehensive pain management. The surgical duration, incision length, pain-related indicators [resting and activity visual analogue scale (VAS) scores, total dosage of oral morphine, WOMAC scores], knee joint range of motion, first ambulation time after operation, length of hospital stay, and postoperative adverse events.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;There was no significant difference between the two groups in surgical duration, incision length, first ambulation time after operation, length of hospital stay, total dosage of oral morphine, and pre-discharge satisfaction with surgery and WOMAC scores ( &lt;i&gt;P&lt;/i&gt;&gt;0.05). At 4, 12, and 24 hours after operation, the resting and activity VAS scores in the \"cocktail\" group were lower than those in the LB group; at 60 and 72 hours postoperatively, the resting VAS scores in the LB group were lower than those in the \"cocktail\" group, with the activity VAS scores also being lower at 60 hours; all showing significant differences ( &lt;i&gt;P&lt;/i&gt;&lt;0.05). There was no significant difference in the above indicators between the two groups at other time points ( &lt;i&gt;P&lt;/i&gt;&gt;0.05). On the second postoperative day, the sleep scores of the LB group were significantly higher than those of the \"cocktail\" group ( &lt;i&gt;P&lt;/i&gt;&lt;0.05), while there was no significant difference in sleep scores on the day of surgery and the first postoperative day ( &lt;i&gt;P&lt;/i&gt;&gt;0.05). Additionally, the incidence of complications showed no significant difference between the two groups ( &lt;i&gt;P&lt;/i&gt;&gt;0.05).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;The use of LB for LIA in UKA can provide prolonged postoperative pain relief; however, it does not demonstrate a significant advantage over the \"cocktail\" method in terms of short-term analgesic effects or reducing opioid consumption and early functional recovery after UKA.
