About this trial
This study is evaluating whether the timing of an interscalene nerve block affects pain control and recovery after arthroscopic rotator cuff repair surgery.
An interscalene block is commonly used to reduce pain after shoulder surgery. However, it is not known whether administering the block before surgery or after surgery provides better outcomes. Participants undergoing arthroscopic rotator cuff repair are assigned to receive the interscalene block either before the surgical incision or after completion of the procedure.
The study compares postoperative pain levels, opioid medication use, length of hospital stay, and ultrasound imaging quality during block administration between the two groups. Functional recovery is also assessed using patient-reported outcome measures during follow-up.
The investigators hypothesize that administration of the interscalene block before surgery may provide superior early pain control and reduce postoperative opioid requirements while maintaining similar functional outcomes compared with administration after surgery.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Adults aged 18 years or older.
Patients undergoing primary arthroscopic rotator cuff repair.
Presence of a repairable small-, medium-, or large-sized rotator cuff tear confirmed by clinical and imaging evaluation.
Receipt of an ultrasound-guided interscalene nerve block as part of perioperative pain management.
Disqualifiers
Irreparable rotator cuff tears.
Partial-thickness rotator cuff tears not requiring repair.
Revision rotator cuff repair procedures.
Concomitant shoulder procedures that could substantially influence postoperative pain or functional outcomes (e.g., shoulder arthroplasty, fracture fixation).
Trial population
Adult patients undergoing primary arthroscopic rotator cuff repair for repairable rotator cuff tears at a single tertiary referral center. Participants received ultrasound-guided interscalene nerve block either before surgical incision or after completion of surgery according to routine perioperative practice.

Trial outcomes
Primary outcomes
1
Early Postoperative Pain Intensity
Patients' postoperative pain intensity measured using the Visual Analog Scale (VAS) following arthroscopic rotator cuff repair. Pain scores will be compared between pre-procedure and post-procedure interscalene block groups. The scale ranges from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate worse pain intensity.
Time frame

Postoperative Opioid Consumption
Total opioid consumption recorded during the first postoperative 24 hours.
Time frame

Patient-Controlled Analgesia Usage
Number of patient-controlled analgesia (PCA) bolus demands during the postoperative period.
