Brief Summary

This interventional study aims to compare the effectiveness of local multimodal drug periarticular injection in TKA patients with the standard pain control regime that includes opioids, NSAIDs, and other analgesics.

The main questions The investigators strive to answer are:

Is there a significant difference in the severity of pain and functional outcomes when applying periarticular injections? Are there any increased complications when applying the periarticular injections?

Detailed Description

The best pain control regime following TKA is controversial. While opioids have an excellent analgesic effect, they also have many side effects. The investigators are conducting a randomized controlled trial to compare the severity of pain following primary unilateral TKA when multimodal drug periarticular injunction is used with the standard pain control regime. The investigators will enroll patients undergoing primary unilateral TKA and randomly allocate them into one treatment group. The first will undergo the procedure with periarticular injection before the closure is composed of a mixture of 20ml of low body weight bupivacaine 5mg/ml plus 1ml of ketorolac 30mg/ml plus 0.5ml adrenaline 1mg/ml injected in medial and lateral retinaculum, medial and lateral collateral ligaments, quadriceps and patellar tendon, joint capsule, subcutaneous fat, and the second will go standard TKA with pain control using opioids, NSAIDS, and paracetamol. The severity of postoperative pain is the primary outcome studied, as well as preoperative complications and any drug side effects, the data will be collected by a fellow researcher who is blinded to the interventions, and the patients will be blinded too. Randomization will be done by a research fellow who is not involved in patient treatment or care.

Primary Outcome Measures
NameTimeMethod
perception of pain - first assessmentmeasured 12 hours after surgery.

The severity of knee pain in the short postoperative period. As stated by the patient, on a scale of 0 to 10, 0 resents no pain at all, and 10 is the worst pain the participant can imagine.

perception of pain - second assessmentmeasured 24 hours after surgery.

The severity of knee pain in the short postoperative period. As stated by the patient, on a scale of 0 to 10, 0 resents no pain at all, and 10 is the worst pain the participant can imagine.

perception of pain - third assessmentmeasured 48 hours after surgery.

The severity of knee pain in the short postoperative period. As stated by the patient, on a scale of 0 to 10, 0 resents no pain at all, and 10 is the worst pain the participant can imagine.

functional status - first assessmentfirst measurement four weeks after surgery.

a "Knee Score" section (7 items) and a "Functional Score" section (3 items). Both sections are scored from 0 to 100 with lower scores being indicative of worse knee conditions and higher scores being indicative of better knee conditions. here, the investigator assesses the function section.

magnitude of disabling pain according to KSS - first assessmentfirst measurement four weeks after surgery.

a "Knee Score" section (7 items) and a "Functional Score" section (3 items). Both sections are scored from 0 to 100, with lower scores being indicative of worse knee conditions and higher scores being indicative of better knee conditions. Here the investigator assesses the pain section.

magnitude of disabling pain according to KSS - second assessmentfirst measurement six months after surgery.

a "Knee Score" section (7 items) and a "Functional Score" section (3 items). Both sections are scored from 0 to 100, with lower scores being indicative of worse knee conditions and higher scores being indicative of better knee conditions. Here the investigator assesses the pain section.

estimated total blood lossmeasured once 48 hours after surgery.

the total amount of lost blood in the perioperative period and will be calculated using the Gross formula which is estimated by hitting the patients' blood volume by the difference between pre and post-operative hematocrit value divided by the initial hematocrit value

functional status - second assessmentsecond measurement six months after surgery.

a "Knee Score" section (7 items) and a "Functional Score" section (3 items). Both sections are scored from 0 to 100 with lower scores being indicative of worse knee conditions and higher scores being indicative of better knee conditions. here, the investigator assesses the function section.
