Brief Summary:
The objective of this study is to demonstrate the safety and efficacy of an intra-articular analgesics cocktail injection for post-operative patella fracture fixation patients, by comparing post-operative pain relief and functional recovery among study subjects who received the injection and those who did not receive the injection. Secondary objective is to demonstrate the health economic effects of intra-articular analgesics cocktail injection by reducing length of hospital stay and reducing bed-stay related complications.
Detailed Description:
This is a single-centre, double-blinded, randomised control trial that evaluates the efficacy of intra-articular analgesics cocktail injection in post-operative pain relief and functional recovery for fractured patella fixation patients. The recruited study subjects will be randomised to the two study groups respectively in a 1:1 randomisation ratio.
Patella is the largest sesamoid bone in the human body, it acts as the fulcrum of our knee extensor apparatus and is important during the gait cycle. Patella fracture commonly occurs after a fall on a flexed knee. Treatment can be conservative or surgical with open reduction and internal fixation. Patients often experience significant pain around the knee post-operatively, limiting their walking ability and hindering their rehabilitation. As a result, total hospital stay will be prolonged, leading to hospital stay-related morbidity and additional healthcare economic burden.
Previous studies have shown that the use of an analgesic cocktail injection in arthroplasty cases can significantly reduce early postoperative pain and provide better early motion. The cocktail regime is as follows for a unilateral joint:
Ketoralac 15mg Ropivacaine 1% 15ml 0.9% Normal Saline 35ml Adrenaline 1:1000 0.5ml Stacort-A Triamcinolone Acetonide 40mg Total Cocktail Volume \~50ml
After fracture fixation, patients in the intervention group will receive an intra-articular injection of the above analgesic cocktail, while patients in the control group will not receive an injection.
Herein this study, the investigators hope to demonstrate the safety and efficacy of an intra-articular analgesics cocktail injection for post-operative patella fracture fixation patients.
