Correlation of magnetic resonance imaging to arthroscopic findings of stability in juvenile osteochondritis dissecans.

Purpose: To determine the ability of magnetic resonance imaging (MRI) to characterize the stability of osteochondritis dissecans (OCD) fragments in juveniles.

Methods: Twenty-eight consecutive patients underwent surgery for OCD between 2004 and 2008. Of these, 23 patients had adequate preoperative imaging.

The effect of interference screw diameter on soft tissue graft fixation.

Tibial fixation of soft-tissue grafts is a weak link in anterior cruciate ligament reconstruction. Previous studies have examined varying interference screw lengths, screw types and tunnel sizes as means to improve graft fixation. We hypothesized that increasing interference screw diameter would significantly increase the maximum load to failure of the graft and decrease the graft's initial slippage.

Suture versus screw fixation of displaced tibial eminence fractures: a biomechanical comparison.

Purpose: Classification and treatment of tibial eminence fractures are determined by the degree of fragment displacement. A variety of surgical procedures have been proposed to stabilize displaced fractures using both open and arthroscopic techniques. Two common fixation techniques involve use of cannulated screws and sutures tied over an anterior tibial bone bridge.

Assessment of clavicular translation after arthroscopic Mumford procedure: direct versus indirect resection--a cadaveric study.

Purpose: To compare the horizontal stability of the distal clavicle following arthroscopic resection of its lateral end by direct and indirect techniques.

Type Of Study: Biomechanical test of cadaveric specimens.

Methods: We performed arthroscopic distal clavicle resection on 12 fresh-frozen human cadaveric shoulders using direct (group 1, n = 6) or indirect (group 2, n = 6) approaches.

The effects of radiofrequency bipolar thermal energy on human meniscal tissue.

This study performed the first in vitro histological analysis of the effects of bipolar thermal energy on human meniscal tissue. Sixteen fresh human menisci were mounted on a cutting block and placed in a water bath simulating an arthroscopic environment. Each specimen was divided into four sections and randomized to one of four treatment options: 1.
