简要总结
The purpose of this study is to determine whether Minimal Invasive Surgery results in less postoperative pain and better mobilization than conventional technique in Unicompartmental Knee Arthroplasty, provided that both groups receive Local Infiltration Analgesia.
详细描述
Postoperative pain is often moderate to severe following unicompartmental knee arthroplasty. In order to reduce postoperative pain and improve mobilization the minimal invasive technique was developed. After a 8-10 cm skin incision, a medial parapatellar capsule incision in made. The rectus tendon or the vastus medialis are not incised and the patella is not everted.
In recent years The Local Infiltration Analgesia (LIA) technique has been developed to reduce postoperative pain. With this LIA-technique, a long-acting local anesthetic (ropivacaine), a nonsteroidal anti-inflammatory drug (ketorolac), and epinephrine are infiltrated intraoperatively and via an intraarticular catheter postoperatively.
The aim of this study is to investigate if Minimal Invasive Surgery results in less postoperative pain and better mobilization than conventional technique in Unicompartmental Knee Arthroplasty, provided that both groups receive Local Infiltration Analgesia.
