About this study

Official title: Comparison of Preemptive Multimodal Analgesia and Femoral Triangle Block on Early Rehabilitation in ACL Reconstruction: A Prospective, Randomized, Double-Blind Study

This study aims to compare the effects of a preemptive multimodal intravenous analgesia protocol and a femoral triangle block on early postoperative rehabilitation compliance in patients undergoing anterior cruciate ligament (ACL) reconstruction under general anesthesia. Adult patients aged 18 to 65 will be randomized to receive either multimodal intravenous analgesia or femoral triangle block prior to surgery. Rehabilitation compliance will be evaluated using the straight leg raise test, sit-to-stand success, and pain scores at multiple postoperative time points. Secondary outcomes include opioid consumption, incidence of opioid-related side effects.

Read the detailed description

Postoperative pain following anterior cruciate ligament (ACL) reconstruction is typically acute in nature and may hinder early physiotherapy interventions. Effective postoperative pain control is essential for optimizing rehabilitation outcomes by enabling early mobilization, which can reduce the risk of thromboembolic complications, maintain pulmonary function, and mitigate metabolic and endocrine stress responses. Adequate analgesia also helps prevent the development of chronic pain, supports cognitive function, and may shorten hospital stay.

ACL injuries are commonly observed in athletes, as well as middle-aged individuals engaging in recreational activities. The success of ACL reconstruction surgery is highly dependent on early and effective postoperative rehabilitation, particularly muscle strength restoration.

Delayed mobilization following surgery may lead to muscle atrophy, cartilage degeneration, and connective tissue adhesions. Early ambulation and rehabilitation are critical for tissue healing and for maintaining joint function and mobility.

Various methods have been utilized for postoperative analgesia, including patient-controlled epidural analgesia, intravenous patient-controlled analgesia (PCA), peripheral nerve blocks, and intra-articular local anesthetic infiltration. Multimodal analgesia protocols have demonstrated superior outcomes in terms of pain control, opioid-sparing effects, and patient satisfaction when compared with single-modality approaches.

This prospective, randomized, double-blind clinical trial will compare the effects of preemptive intravenous multimodal analgesia and femoral triangle block on early postoperative rehabilitation compliance in adult patients undergoing ACL reconstruction under general anesthesia. The interventions are routinely used in clinical practice and are recognized as safe and effective.

The primary objective is to evaluate whether either approach improves compliance with early rehabilitation tasks. Compliance will be assessed using functional recovery metrics including the straight leg raise test, sit-to-stand success, and patient-reported pain scores using the Numerical Rating Scale (NRS) at predefined postoperative time points.

Secondary endpoints include total opioid consumption, frequency of opioid-related adverse events (e.g., nausea, vomiting, itching), and overall patient satisfaction. This study addresses a current gap in the literature, as no previous trials have directly compared these two methods in this clinical context.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Preemptive Multimodal Intravenous AnalgesiaDrug

    Also called Multimodal Analgesia, IV Pain Management Protocol

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Compliance with Straight Leg Raise Test (SLR)

    This outcome measure evaluates the patients' ability to perform the straight leg raise test (SLR) at various postoperative time points. The NRS (Numeric Rating Scale) score will be used to assess the pain during these activities. NRS (Numeric Rating Scale) for pain during the activity. Scale: 0 (no pain) to 10 (worst pain). Higher scores on the NRS indicate worse pain.

    Measured: Postoperative 2, 6, 12 and 24 hours

  2. Standing Ability

    This outcome measure evaluates the patients' ability to stand after surgery at various postoperative time points. The NRS (Numeric Rating Scale) score will be used to assess the pain during these activities. NRS (Numeric Rating Scale) for pain during the activity. Scale: 0 (no pain) to 10 (worst pain). Higher scores on the NRS indicate worse pain.

    Measured: Postoperative 2,6,12 and 24 hours

Secondary outcomes (2)
  1. Total Opioid Consumption

    The total amount of opioids consumed by the patients in the first 72 hours after surgery will be recorded and compared between the two groups.

    Measured: Postoperative 2, 6, 12, 24, 48, and 72 hours

  2. Incidence of Opioid-Related Side Effects

    The incidence of opioid-related side effects, such as nausea, vomiting, and itching, will be recorded and compared between the two groups.

    Measured: Postoperative 2, 6, 12, 24, 48, and 72 hours
