Summary

Effective pain relief allows the patients to obtain early knee mobilization and optimal rehabilitation and thus improves the patient satisfaction.

The aim of perioperative pain control is to minimize delays in recovery, postoperative delirium and pain-related stress responses that can lead to serious morbidity and poor outcomes. Numerous approaches to effectively control postoperative pain in TKA patients have been evaluated, as poorly controlled acute postoperative pain can be associated with persistent pain. Furthermore, increased pain intensity after surgery on the second knee seems to be closely associated with chronic post-TKA pain, with similar mechanisms underlying hyperalgesia or chronic pain.

Conditions

  • Postoperative Pain

Interventions

PROCEDURE

periarticular infiltration

The cocktail will be injected at the following 7 anatomical zones as follows: Zone 1: medial retinaculum Zone 2: medial collateral ligament and medial meniscus capsular attachment Zone 3: posterior capsule Zone 4: lateral collateral ligament and lateral meniscus capsular attachment Zone 5: lateral retinaculum Zone 6: patellar tendon and fat pad Zone 7: cut ends of quadriceps muscle and tendon Injection at zones 2, 3, and 4 will be administered after making the tibial and femoral cuts and ligament balancing. At zones 1, 5, 6, and 7, the injection will be administered after implant placement.

PROCEDURE

genicular nerve block

The genicular arteries will be identified near the periosteal areas, which are the junctions of the epicondyle and the shafts of the femur and tibia, and confirmed by color Doppler ultrasound. genicular nerve block target points should be next to each genicular artery because the superior lateral, superior medial, and inferior medial genicular artery traveled along each genicular nerve.After using color Doppler to confirm the genicular artery, the needle will be inserted in the plane of the ultrasound probe in the long-axis view.
