Brief summary
The Quality of Recovery 40 (QoR-40) is a multidimensional questionnaire that addresses many aspects of postoperative recovery. The QoR-40 has been used many times to measure the recovery of patients after different surgeries, and this questionnaire seems to be a reliable tool for evaluating anesthesia-related techniques, including regional anesthesia. Arthroscopic knee surgery causes moderate to severe postoperative pain for most patients. Various methods such as different systemic drugs, peripheral or central blocks and intra-articular injections have been developed for the effective, safe and long-term control of this pain. In recent years, it has been shown that regional anesthesia techniques reduce the need for opioids in orthopedic ambulatory surgeries and accelerate recovery and discharge. However, there is no consensus on which is the best approach among these various regional techniques. However, adductor canal block (ACB) and intrathecal morphine (ITM) are the preferred regional methods in the perioperative pain management of knee surgery. In this study, it was aimed to test the effectiveness of intrathecal morphine or adductor canal block added to spinal anesthesia on the quality of recovery in patients undergoing arthroscopic anterior cruciate ligament reconstruction surgery.
Interventions
DRUGIntrathecal morphine
The study will be conducted in patients undergoing arthroscopic anterior cruciate ligament reconstruction surgery under spinal anesthesia. In this arm, 0.1 mg intrathecal morphine in addition to spinal anesthesia will be used for perioperative pain management. A placebo addctor canal block will also be performed for masking in these patients. The quality of recovery will be evaluated with a postoperative quality of recovery scale (QoR-40 questionnaire) at postoperative 24-hour and 14-day.
DRUGAdductor canal block
After providing complete sensory block in the lower extremities with spinal anesthesia, the thigh where the surgery will be performed will be brought into slight abduction and external rotation while the patient is in the supine position. The blockage of the saphenous nerve in the adductor canal will be performed with 30 mL of local anesthetic (0.25% bupivacaine) solution with a 22 gauge 5-8 cm long block needle from the mid-medial part of the thigh under ultrasound guidance. The quality of recovery will be evaluated with QoR-40 questionnaire at postoperative 24-hour and 14-day.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 24-hour Quality of Recovery-40 (QoR-40) questionnaire scores | Postoperative 24-hour. | The score ranges from 40 to 200. A higher score on the QoR-40 means better recovery following arthroscopic anterior cruciate ligament reconstruction. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Numeric Rating Score (NRS) | Postoperative 1, 2, 4, 8, 12 and 24-hour. | Numeric rating score for postoperative pain intensity. Pain intensity will be evaluated using a numeric rating scale with descriptive terms at intervals along a horizontal line of 10 cm length: 0 mm = no pain, 10 cm = worst pain imaginable. |
| Supplement analgesia requirement | Postoperative 1, 2, 4, 8, 12 and 24-hour. | Amount of additional analgesics taken outside of the usual treatment protocol. |
| The time to first postoperative mobilisation | Duration of postoperative 24-hour | Ambulation time |
| Discharge time | Duration of postoperative 24-hour | Length of hospital stay |
| Treatment satisfaction | Postoperative 24-hour | Treatment satisfaction will be assessed at 24 h using a 3-point rating scale ranging from 1 to 3: 1 = excellent satisfaction (Numeric Rating Score/NRS=0), 2 = good satisfaction (NRS=1-2), 3 = dissatisfaction (NRS=3-4) |
