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.

Outcome Measures
Primary Outcomes (6)
Pain as measured by Numerical Patient Reported Scale (NRPS)
Numerical Patient Reported Scale (NRPS), 0 (no pain) to 10 (worst pain imaginable)
Pre-op, Post-op Day 1 to 3
Maximum Active Knee Flexion
The patient's Knee flexion is measured by a physiotherapist
At post-op Day 1 to 3
Oral analgesics consumed
The level of the analgesic consumed (non-opioids, weak opioids, strong opioids), and the frequency of consumption
Post-operative 2 weeks period
Tegner Lysholm Knee Score
The Lysholm Knee Score calculates and grades an overall score from 0 to 100 based on 8 domains: squatting, locking, pain, stair climbing, support, instability, and edema. Scores between 95 and 100 are regarded as exceptional, 84 and 94 as acceptable, 65 to 83 as fair, and less than 65 as poor.
Post-op Day 14
Knee Injury and Osteoarthritis Outcome Score (KOOS)
The KOOS's five patient-relevant dimensions are scored separately: Pain (nine items); Symptoms (seven items); ADL Function (17 items); Sport and Recreation Function (five items); Quality of Life (four items). A Likert scale is used, and all items have five possible answer options scored from 0 (No problems) to 4 (Extreme problems), and each of the five scores is calculated as the sum of the items included. Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems as common in orthopaedic scales and generic measures. Scores between 0 and 100 represent the percentage of total possible score achieved.
Post-op Day 14
9-item Quality of Recovery Score (QoR-9 Score)
The QoR-9 has 9 questions evaluating the quality of recovery after surgery and anaesthesia. It is a patient-rated score ranging from 0 (worst) to 2 (best).
Post-op Day 1 to 3

Study Arms (2)
Intra-Articular Cocktail Injection
EXPERIMENTALAfter fixation, an intra-articular cocktail injection is injected into the surgical site. The intra-articular cocktail regime: Ketoralac 15mg, Ropivacaine 1% 15ml, 0.9% Normal Saline 35ml, Adrenaline 1:1000 0.5ml, Stacort-A Triamcinolone Acetonide 40mg. The total cocktail volume is approximately 50ml.
No Injection
NO INTERVENTIONNo injection will be given to the patient.
Interventions
An intra-articular cocktail injection ( Ketoralac 15mg, Ropivacaine 1% 15ml, 0.9% Normal Saline 35ml, Adrenaline 1:1000 0.5ml, Stacort-A Triamcinolone Acetonide 40mg) will be injected into the surgical site after fracture fixation surgery.
