Clinical Effect Of Intermittent Multiple IPAK Block On Flexion Contracture Of Knee Arthritis At 5°-10° After TKA

Objective:To explore the analgesic effect of IPAK block on knee arthritis after TKA,and whether repeated intermittent IPAK block is beneficial to the rehabilitation of knee arthritis with mild flexion contracture after TKA.Methods:Patients in the experimental group received intermittent ACB combined with intermittent IPAK,while patients in the control group received only intermittent ACB block.Nerve block was performed by the same anesthesiologist,and the postoperative nursing team recorded pain scores,walking distance,and the degree of recovery from flexion contracture.Results:A total of 21 cases in the ACB/IPACK group and 21 cases in the ACB group were collected.There was no demographic difference between the two groups.The median pain scores at resting and 45° knee flexion did not differ between the two groups at any time.However,there were significant differences in pain scores between the two groups at each time period when the leg was pressed and when POD0,POD1 was in the morning,POD1 was in the afternoon and POD2 was in the morning.There were some differences in the recovery time of flexion contracture and the time to reach phasic goal 2 between the two groups.However,there was no difference between the two groups in walking distance and time to reach stage goal1.Conclusion:In the ACB/IPACK group,the pain scores were lower during leg pressing and PODO,POD1 in the morning,POD1 in the afternoon,and POD2 in the morning.The residual flexion contracture recovered more quickly in the ACB/ IPAK group than in the ACB group.Phase goal 2 was achieved earlier in the ACB/ IPAK group than in the ACB group.The addition of IPAK block in the multimodal analgesia scheme after TKA can relieve the pain of postoperative physical therapy and facilitate postoperative recovery.IPAK block has a good indication for patients who are difficult to tolerate the pain of rehabilitation after TKA.
