About this study
Official title: Does Periarticular Injection (PAI) Reduce Pain After TKA Among Knee Arthroplasty Patients Receiving Adductor Canal Block and Infiltration Between the Popliteal Artery and the Capsule of the Posterior Knee (ACB&IPACK)? A Blinded, Randomized Controlled Trial.
The goal of this clinical trial is to determine whether Periarticular Injection (PAI) alongside Adductor Canal Block (ACB) and Infiltration between the Popliteal Artery and Capsule of the Knee (IPACK) block can decrease post-operative pain in patients undergoing primary total knee arthroplasty. The main question it aims to answer is:
- Is ACB/IPACK without PAI as effective as ACB/IPACK with PAI for TKA patients?
Participants will be assigned to one of the following groups at random:
- ACB/PACK with PAI
- ACB/IPACK with saline injection
Participants will also be asked to complete pre- and post-operative questionnaires.
Read the detailed description
Kim et al (2019) have shown that addition of ACB/IPACK to PAI improves analgesic outcomes (the nerve blocks reduced pain with ambulation and reduced opioid consumption). TKA patients receiving PAI + ACB/IPACK (along with a comprehensive multimodal analgesic program) had low pain scores with ambulation on POD1: 1.7 +/- 1.4 (mean +/- SD, NRS, 0-10 scale). The opioid consumption in the first 24 hours was 40.6 +/- 32.1 (mg oral morphine equivalents).
It is not clear if the PAI component is necessary, given the theoretically nearly complete analgesic effects of the ACB/IPACK block. Additionally, anecdotal evidence indicates that some surgeons at HSS routinely use the PAI and some do not, without obvious large differences in analgesic outcomes. While there may be a 'belt and suspenders' advantage to using PAI in addition to ACB/IPACK, it is not desirable to perform unnecessary procedures.
In this study, we seek to compare the efficacy of ACB/IPACK with and without PAI in TKA patients.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Periarticular Injection (PAI)Drug
PAI is a widely-utilized, surgeon-performed, analgesic intervention for TKA patients.
Saline Control Periarticular Injection (PAI)Drug
equal volume of saline will be used in place of analgesics used in PAI injections
| Study group | Role | What they receive |
|---|---|---|
| No PAI + ACB & IPACK | Placebo comparator | Control: saline injection (same injection technique and volumes as described for the active intervention, of normal saline) Receives: Drug: Saline Control Periarticular Injection (PAI) |
| PAI + ACB & IPACK | Active comparator | Active intervention: Periarticular injection: one deep injection prior to cementation and then a second more superficial injection prior to closure. The deep injection will consist of bupivacaine 0.25% with 1:200,000 epinephrine, 30 cc; morphine, 8 mg/ml, 1cc; methylprednisolone, 40 mg/ml, 1 ml; cefazolin, 500 in 10 ml; normal saline, 22cc. The superficial injection will be 20 ml 0.25% bupivacaine Receives: Drug: Periarticular Injection (PAI) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pain Scores (NRS, 0-10) With Ambulation on POD1
The NRS (numeric rating scale) is a questionnaire that measures pain on a numeric scale, 0 (no pain) to 10 (worst pain imaginable). The questionnaire will be asked on post operative discharge day 1.
Measured: 24 hours Post Operative Discharge
Secondary outcomes (17)
Opioid Use (Cumulative Oral Morphine Equivalents POD0-POD2, 2 Weeks, 3 Months)
Cumulative opioid consumption in morphine equivalents will be recorded post surgical discharge, 24h post surgical discharge, 48 hours post surgical discharge, 2 weeks post surgical discharge, and 3 months post surgical discharge.
Measured: post surgical discharge, 24 hours post surgical discharge, 48 hours post surgical discharge, 2 weeks post surgical discharge, and 3 months post surgical discharge.
NRS Pain With Movement
The NRS (numeric rating scale) is a questionnaire that measures pain on a numeric scale, 0 (no pain) to 10 (worst pain imaginable). The questionnaire will focus on pain during movement and will be asked at pre-operation, in the post anesthesia care unit (PACU), at post operative (POD) 1, POD 2, and POD 3 months.
Measured: pre-operation, in the post anesthesia care unit (PACU), at post operative (POD) 1, POD 2, and POD 3 months
Numerical Rating Scale (NRS) Pain Score at Rest
The NRS (numeric rating scale) is a questionnaire that measures pain on a numeric scale, 0 (no pain) to 10 (worst pain imaginable). The questionnaire will focus on pain without movement involved and will be asked at pre-operation, post anesthesia care unit (PACU), post operative day (POD) 1, POD 2, and POD 3 months
Measured: from pre-operation, post anesthesia care unit (PACU), post operative day (POD) 1, POD 2, and POD 3 months
PAIN OUT Questionnaire at Preoperation
The PAIN OUT questionnaire has multiple numeric scale questions on pain relief as well as pain intensity, along with Yes/No questions. There are also questions asking which pain relief techniques were used (multiple choice). All questions are scored on a scale of 0 to 10, with 0 meaning no pain/does not interfere/not at all and 10 meaning worst pain/completely interferes/extremely. A higher score means a worse outcome.
Measured: at preoperation
Quality of Recovery (POD1)
Quality of Recovery (QoR-9), This questionnaire has three options for scale (not at all, some of the time, most of the time).
The QoR-9 is a nine-item scale. Total QoR-9-scores range from 0 to 18, with higher scores indicating good recovery after anaesthesia.
The questions focus on the overall well being of the patient. The questionnaire will be asked 24 hours post surgical discharge.
Measured: 24 hours post surgical discharge.
Side Effects: Opioid-Related Symptom Distress Score (POD1)
The Opioid-related symptom distress scale evaluates frequency, severity, bothersomeness for 12 symptoms. Each symptom is scored on a 4-point scale, with 0 meaning better outcome and 4 meaning worst outcome. The questionnaire will be asked 24 hours (POD 1) post surgical discharge.
Measured: 24 hours (POD 1) post surgical discharge.
Satisfaction With Pain Management (POD1)
This questionnaire is a numeric scale from 0 (strongly dissatisfied) to 10 ( strongly satisfied). A higher number dictates a better outcome. This will be asked 24 hours post operative discharge.
Measured: 24 hours post operative discharge.
Blinding Assessment; Bang Question (POD1)
There is no numeric scale for this questionnaire. It focuses on asking the subjects and the research assistant, which group they believe the subject were randomized to. This will be asked 24 hours post operative discharge.
Measured: 24 hours post operative discharge
Douleur Neuropathique en 4 Questions (DN4) at Pre-operation, 3 Months
The DN4 ( Douleur Neuropathique en 4 Questions) is a Yes/No questionnaire aimed at uncovering neuropathic pain symptoms. Each question is scored as yes or no, with yes = 1 point and no = 0 points. Total score is calculated by summing the total of the individual question scores, for a total score range of 0-10, with a score of greater than or equal to 4 indicating the patient may be suffering from neuropathic pain. The average score across all participants is calculated and reported for each time point.
Measured: Pre operative, 3 months post operative discharge.
Knee Injury and Osteoarthritis Outcome Score for Joint Replacement
The standard Knee injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS Jr.) questionnaire will be asked to evaluate orthopedic outcomes. The KOOS, JR contains 7 items from the original KOOS survey. Items are coded from 0 to 4, none to extreme respectively.
KOOS, JR is scored by summing the raw response (range 0-28) and then converting it to an interval score. The interval score ranges from 0 to 100 where 0 represents total knee disability and 100 represents perfect knee health.
The questionnaire will be asked preoperatively, 6 weeks post operative discharge, 3 months post operative discharge.
Measured: preoperatively, 6 weeks post operative discharge, 3 months post operative discharge

A Phase 4 study testing Periarticular Injection (PAI) in people with Total Knee Athroplasty, run by Hospital for Special Surgery, New York at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 Jun 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pain Scores (NRS, 0-10) With Ambulation on POD1 (time frame: 24 hours Post Operative Discharge). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Dec 2024.
