Randomized Controlled Trial Comparative Study Clinical Trial
Patient-controlled ropivacaine analgesia after arthroscopic subacromial decompression.
To evaluate the efficacy of a subacromial patient-controlled analgesia (PCA) infusion of 0.2% ropivacaine versus saline for postoperative pain control following arthroscopic shoulder surgery. ⋯ Level I.

Randomized Controlled Trial Comparative Study Clinical Trial
Arthroscopic versus open treatment of Bankart lesion of the shoulder: a prospective randomized study.
The purpose of this study was to compare the results of arthroscopic and open repair of isolated Bankart lesions of the shoulder using metallic suture anchors. ⋯ Level I.

Comparative Study
In vivo comparison of a metal versus a biodegradable suture anchor.
This protocol compares an absorbable polylactic acid (PLA) anchor to a similarly sized metallic anchor, comparing the load to failure of the suture anchor construct in vivo in a goat model. ⋯ This study provides the reader with an evaluation of the in vivo function and holding strength over time of implantation of an absorbable suture anchor in comparison with a metal anchor.

Some controversy exists regarding the effects of radiofrequency (RF) probes on articular cartilage. To further elucidate these effects, we examined the chondrocyte viability and metabolic activity after treatment of fresh bovine articular cartilage with bipolar RF probes. ⋯ The 2 bipolar radiofrequency probes tested created a well-controlled debridement in normal articular cartilage with smooth edges and a defined margin of chondrocyte death that extended approximately 100 to 200 microm into the treatment area.
