A Double Blind Randomized Control Trial on the Efficacy of Periarticular Levo Bupivicaine Injection Following Primary Hip Arthroplasty
In Brief
A Phase 4 clinical trial evaluating Levobupivacaine and Saline for Osteoarthritis. Completed, enrolled 91 participants across 2 sites.
Detailed Summary
The hypothesis of this study is that isolated use of local periarticular levobupivicaine injection during primary hip arthroplasty would improve post-operative pain control. Patients were randomised in the operating room to receive either a periarticular infiltration, or a placebo consisting of Saline. Morphine and analgesic consumption was recorded for each patient, while the modified McGill pain scale was used to determine the adequacy of analgesia and the benefit of the peri-articular infiltration. 91 patients were recruited, with 45 patients in the treatment group and 46 controls. The results were assessed after one year, once all the information from both treatment groups was collected.

Timeline
Interventions
The treatment group received 150mg of levobupivicaine in 60mls of 0.9% saline. This was injected intra-operatively through the medial and anterior capsular spaces in the region of the obturator and femoral nerves and also around the short rotators and gluteus maximus in the region of the inferior and superior gluteal nerves. The timing of this was after insertion of the acetabular component. 10mls was then infiltrated around the tensor fascia lata and subcutaneously prior to closing the wound.
The placebo group received 60mls of 0.9% saline injected intra-operatively through the medial and anterior capsular spaces in the region of the obturator and femoral nerves and also around the short rotators and gluteus maximus in the region of the inferior and superior gluteal nerves. The timing of this was after insertion of the acetabular component. 10mls was then infiltrated around the tensor fascia lata and subcutaneously prior to closing the wound.
