Intra-Articular Dislocation of the Patella With Associated Hoffa Fracture in a Skeletally Immature Patient.

Since 1887, approximately 50 cases of an intra-articular patellar dislocation have been reported in the worldwide literature. The vast majority of patients required an open reduction of the patella or closed reduction under general anesthesia. This injury has never been reported in association with a coronal shear fracture of the femoral condyle.

Staged treatment of a chronic patellar sleeve fracture using the Taylor spatial frame.

Patellar sleeve fractures are easily missed injuries since plain radiographs may not show a bony fragment at the time of injury. Failure to diagnose these injuries can result in patellar instability, extensor lag, and anterior knee pain. We report a novel treatment using a Taylor spatial frame as part of a staged reconstruction to regain length of the extensor mechanism and maintain knee motion prior to performing primary repair of the avulsed patellar sleeve fragment.

Athletes' ankle injuries: diagnosis and management.

Ankle injuries are common in the general and athletic populations. These injuries constitute 21% of all sports-related injuries. The wide spectrum of sports-related ankle injuries includes ligamentous injuries, soft-tissue and osseous impingement, osteochondral lesions of the talus, tendon injuries, and fractures.

Chlorhexidine provides superior skin decontamination in foot and ankle surgery: a prospective randomized study.

Unlabelled: Feet are prone to bacterial contamination. We hypothesized that chlorhexidine scrub and isopropyl alcohol paint provide superior local flora reduction than povidone-iodine scrub and paint. Patients with intact, uninfected skin having clean elective foot and ankle surgery were prospectively enrolled and randomly assigned to skin preparation with povidone-iodine (Group 1) or chlorhexidine scrub and isopropyl alcohol paint (Group 2).

Strength and knot security of braided polyester and caprolactone/glycolide suture.

Background: Appropriate suture selection is necessary in providing mechanical stability to soft tissue reconstructions. Caprolactone/glycolide (Panacryltrade mark) became a popular suture, possessing excellent handling properties; however, clinical observations questioned the knot security of caprolactone/glycolide. Caprolactone/glycolide is still available on many commercial suture anchor systems.

Histologic findings with a bioabsorbable anterior cruciate ligament interference screw explant after 2.5 years in vivo.

We retrieved a high-molecular-weight poly-L-lactic) (PLLA) anterior cruciate ligament (ACL) interference screw (Arthrex, Naples, FL) after 30 months in vivo during revision ACL surgery. Gross, histologic, histomorphometric, and molecular weight measurements were carried out on the implant and the surrounding bone. These studies showed a 75% decrease in the molecular weight of the screw, with implant fragmentation and new bone formation adjacent to the screw and graft.
