Arthroscopic "second look" at the GORE-TEX ligament.

We performed an arthroscopic "second look" in 21 knees (20 patients) that had arthroscopic implantation of the GORE-TEX prosthesis for chronic ACL insufficiency. Arthroscopy was done on eight knees at the time of screw removal, eight for knee pain, two for giving way, and three for recurrent effusions. The degree of synovial joint reaction, graft synovial ingrowth, and graft rupture was graded. Microscopic examination was carried out on all biopsies of the GORE-TEX ligament. The average patient age was 30 years and the average time interval from original implantation to second look was 11 months. The GORE-TEX was intact in 11 knees, 10% ruptured in 6, and completely ruptured in 4. There was no correlation between number of GORE-TEX strands ruptured and synovial reaction. No particles of the graft were noted in the synovium if the implant was intact, but particles were noted with graft rupture. We conclude that the intact GORE-TEX ligament is an inert substance and does not cause significant joint reaction. Impingement in the intercondylar notch appeared to be the most common cause of graft failure. Further study is critical to determine the natural history of the GORE-TEX ligament and the knees' response to this prosthetic device.

Surgical repair of chronic complete hamstring tendon rupture in the adult patient.

Complete rupture of the hamstring tendons in the adult is a rare injury. This report discusses complete rupture of the hamstring tendons in nine patients treated by late operative repair. All patients were referred from outside centers for a second opinion after failed nonoperative treatment. The diagnosis was made quite easily on clinical grounds and was confirmed at surgery. Surgical treatment in all cases consisted of reattachment of the hamstring tendons to the origin on the ischium, and in all cases it was necessary to perform neurolysis of the sciatic nerve. Good results were achieved in all cases, at follow-up all patients were satisfied with the surgery.

Leak rate of latex gloves after tearing adhesive tape.

Anesthesiologists use latex gloves to provide barrier protection against infectious disease or contamination while providing anesthetic services. The performance of these services often involves tearing tape. The purpose of this study was to test the effect of tearing adhesive tape on permeability of latex examination gloves and to test the effect of an adhesive-sparing moisturizing cream on permeability of latex gloves used to tear adhesive tape. In a blinded, randomized, controlled laboratory experiment, 48 nonsterile latex examination gloves (24 pairs) were randomized to 1 of 2 groups. Adhesive-sparing moisturizing cream, 0.1 mL, was applied to 12 glove pairs; the remaining 12 pairs served as controls. Each of the 24 pairs of gloves were used to tear five 4-cm strips of cloth adhesive tape from a standard 1 1/2-inch roll. After initial inspection for obvious tears, each glove was tested for leaks using the watertight test as specified by the American Society for Testing and Materials (ASTM). Data recorded included the identity of the investigator tearing tape, number of holes initially observed, number of holes observed from the ASTM test, location of holes, glove classification as right or left hand, and treatment group. Based on the study, the authors concluded that health care providers who tear adhesive tape while wearing latex gloves should be aware that there is a high probability that the gloves no longer form a protective barrier and that adhesive-sparing moisturizing cream applied before tape is torn increases barrier protection.

A comparative study of two securement techniques for short peripheral intravenous catheters.

Previous studies have examined complications with short peripheral catheters, although focus on securement techniques and the relation to catheter dislodgment as an early indicator of potential intravenous complications is limited. The purpose of this study was to examine two methods of peripheral catheter securement: transparent dressing and tape (control group) versus transparent dressing and StatLock i.v./PICC (study group) and their effects on i.v. complications. One hundred five peripheral catheters were evaluated. The use of transparent dressing and StatLock showed a 45% reduction in overall i.v. therapy complications when compared with that of transparent dressing and tape (P = 0.025). In addition, catheter dislodgment episodes were reduced by 40% (P = 0.002) with the average dwell time extended by 21 hours.
