This study seeks to compare the pullout strength of various anchor configurations in an osteoporotic bone model. We have tested and present here a technique designed to augment the pullout resistance of an anchor in poor-quality bone with the use of a second anchor as an interference fit; this report describes our in vivo results with this procedure. ⋯ Data from this study may be useful for the arthroscopic surgeon in choosing the proper anchor construct for osteoporotic bone. This study also lends support to the technique of press-fitting an anchor against an anchor in the loose screw situation.

Randomized Controlled Trial Comparative Study
Purely intra-articular versus general anesthesia for proposed arthroscopic partial meniscectomy of the knee: a randomized controlled trial.
The aim of this study was to compare intra-articular anesthesia alone versus general anesthesia with regard to ease of the procedure, level of postoperative pain, and patient satisfaction when partial meniscectomy is anticipated. ⋯ Level I, high-quality randomized controlled therapeutic trial.

To investigate whether diclofenac could be used in preemptive and multimodal fashion with local anesthesia (LA) during arthroscopic knee surgery. ⋯ Level IV, therapeutic case series.

The purpose of this study was to prospectively evaluate the surgical outcome of arthroscopic Bankart repair via suture anchors in patients with recurrent traumatic anterior shoulder instability with a minimum follow-up of 2 years. ⋯ Level IV, therapeutic case series.

The suprascapular notch is a common location for entrapment of the suprascapular nerve. Open surgical procedures for excision of the transverse scapular ligament are associated with pain relief and functional improvement. Arthroscopic procedures have been described for decompressing ganglion cysts, which compress the nerve at the spinoglenoid notch. ⋯ Arthroscopic identification of structures around the notch is necessary before ligament resection. A new suprascapular portal, in combination with an accessory portal, is described for retraction, blunt dissection, nerve stimulation, and ligament resection. Key instruments include a 4-mm arthroscope of standard length (160 mm), with a 70 degree angled lens for adequate visualization and a calibrated probe to guide and limit dissection.
