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.

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.

Bioabsorbable interference screws have proved to be biologically safe and to provide adequate graft fixation. Metallic interference screws have therefore been continuously replaced over the years. However, degradation times are highly variable, and bony replacement of the screw does not always occur in human beings. Composite interference screws have recently been introduced to enhance bony integration. We evaluated 2 different composite interference screws and compared them with an allograft interference screw over a 2-year period after anterior cruciate ligament (ACL) reconstruction with an autologous bone-patellar tendon-bone graft. ⋯ At 24 months, no advantage of composite screw materials over conventional bioabsorbable screws could be detected. If composite materials will be of any advantage with respect to bony replacement has to be observed with longer-term follow-up. The allograft bone screw was completely incorporated and replaced by cancellous bone after 24 months. Unfortunately, the screw's more complicated handling, higher cost, and limited availability impair the possibilities for its standard clinical use.

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.

The purpose of this study was to investigate the intermediate-term postoperative results of arthroscopic surgery for lateral compartment osteoarthritis (OA) of the knee in a case series study. ⋯ Level IV, therapeutic case series.
