Randomized Controlled Trial Comparative Study
The efficacy of continuous bupivacaine infiltration following arthroscopic rotator cuff repair.
This prospective, randomized, double-blind study with a placebo group and 2 experimental groups evaluated the efficacy of continuous low-dose bupivacaine infiltration by infusion pump after arthroscopic rotator cuff repair. ⋯ Level II, randomized controlled trial of therapeutic treatment that lacks statistical significance and narrow confidence intervals.

The beach-chair position in shoulder surgery provides advantages to the surgeon and anesthesiologist. However, cautious interpretation of the patient's blood pressure is essential, especially when the blood pressure cuff is placed at the calf. The calf pressure should be interpreted relative to the heart-level pressure to avoid iatrogenic cerebral hypoperfusion related to hypotensive anesthesia. Possible complications of cerebral hypoperfusion are permanent neurologic impairment, stroke, and death.

Comparative Study
A biomechanical comparison of two suture anchor configurations for the repair of type II SLAP lesions subjected to a peel-back mechanism of failure.
The purpose of this study was to biomechanically compare 2 different suture anchor configurations in the repair of type II SLAP lesions. ⋯ Placement of an anterior suture anchor could, theoretically, tension the anterior capsulolabral structures via the superior and middle glenohumeral ligaments to the superior labrum. The results of this study suggest that there is no biomechanical advantage to placing an anterior suture anchor and so the use of 2 posterior suture anchors may be preferable in the repair of type II SLAP lesions.

The purpose of this study was to evaluate the efficacy of hylan G-F 20 when used to treat an active and athletic patient population with knee osteoarthritis who had undergone knee arthroscopy for mechanical symptoms. ⋯ Level IV, therapeutic case series.

The purpose of this study was to determine if three-dimensional computed tomography (3-D CT) scans of the glenoid can be used to accurately quantify, by means of a glenoid index, bone loss in patients with anterior glenohumeral instability, and to compare the results with arthroscopic measurements to determine if the 3-D CT scan can preoperatively predict which patients with anterior glenohumeral instability will benefit from a bone grafting procedure. ⋯ Level III, development of diagnostic criteria with universally applied reference (nonconsecutive patients).
