Ten cadaveric shoulders (mean donor age, 60.5 years) underwent arthroscopic placement of capsulolabral sutures as performed during arthroscopic reconstruction for shoulder instability. In relation to the glenoid face, the sutures were placed anterior, anteroinferior, inferior, posteroinferior, and posterior. All sutures entered the capsule approximately 1 cm away from the glenoid and exited beneath the labrum, and were tied using arthroscopic knot-typing techniques. ⋯ In no specimen was any suture closer to the axillary nerve than 7 mm. We noted a statistically significant trend for the nerve to lie closest to the anteroinferior suture and gradually recede from the remaining sutures lying more posteriorly. This anatomic study is the first to demonstrate a relatively safe margin for arthroscopic suture placement between the capsule and axillary nerve when these sutures are placed approximately 1 cm from the glenoid rim.

Randomized Controlled Trial Comparative Study Clinical Trial
Preemptive analgesia: its role and efficacy in anterior cruciate ligament reconstruction.
As more outpatient orthopaedic surgical procedures are performed, postoperative pain control has gained importance. The benefits of preemptive analgesia, the use of analgesics or anesthetics or both before painful stimuli to prevent or reduce pain, have been widely published in the anesthesia and general surgery literature, but not in orthopaedic literature. We prospectively compared the effects, on postoperative pain and narcotic use, of intraarticular preoperative injections of 1) placebo with epinephrine, 2) bupivacaine with epinephrine, and 3) bupivacaine and morphine with epinephrine. ⋯ However, intravenous narcotic pain medication was administered in the recovery room to patients with pain scores greater than 5, equalizing pain scores. Group 3 used significantly less postoperative narcotic medication than group 1. Preemptive analgesia using intraarticular bupivacaine and morphine with epinephrine resulted in lower pain scores during the 1st hour after an arthroscopic anterior cruciate ligament reconstruction than did preemptive treatment with bupivacaine and epinephrine or placebo and epinephrine.
