SymbolEffect of intra- and peri-operative analgesia on the recovery of joint function following total knee arthroplasty

BACKGROUND:

Pain control following artificial total knee arthroplasty (TKA) is a key concern for orthopedic surgeons. Although analgesis techniques have been improved in recent years, they have specific disadvantages.

OBJECTIVE:

To asses the effect of a multimodal pain management protocol in primary TKA.

METHODS:

A total of 30 patients, including 5 males and 25 females, undergoing primary unilateral TKA were selected and randomly assigned to 2 groups. Trial group was treated with cyclooxygenase-2 inhibitor, periarticular ropivacaine infiltration analgesia and femoral nerve block to pain control. Control group received cyclooxygenase-2 inhibitor and patient-controlled analgesia (PCA). The pain severity and range of motion (ROM) in patients was observed postoperatively.

RESULTS AND CONCLUSION:

A multimodal protocol that emphasizes local periarticular injections after TKA provides better pain control and improved postoperative ROM of troubled knee in early time compared with control group. Multimodal pain management that emphasizes local periarticular infiltration analgesia in peri-operative period of TKA could provide better pain control and improved function of the knee.
