Investigation of the Optimal Interval for Staged Total Knee Arthroplasty for the Treatment of Advanced Bilateral Gonarthrosis.

PURPOSE OF THE STUDY This study investigated whether there was an optimal interval between two operations for total knee arthroplasties in patients with advanced bilateral gonarthrosis scheduled to undergo staged total knee arthroplasty (TKA). MATERIAL AND METHODS A prospective cohort of 219 patients (136 females, 83 males) undergoing staged total knee arthroplasty for the treatment of advanced bilateral gonarthrosis were followed for up to 12 months. The mean was 69.

Mid-Term Results of Two Different Fixation Methods for Chevron Osteotomy for Correction of Hallux Valgus.

We compared 2 different fixation methods (bioabsorbable pins and cannulated screws) after chevron osteotomy for the treatment of hallux valgus. We reviewed consecutive proximal chevron osteotomies in 80 patients (100 feet) performed by 2 surgeons. Of the 100 feet (80 patients), 48 feet (40 patients) were stabilized with bioabsorbable pins, and 52 feet (40 patients) were stabilized with cannulated screws.

Surgical treatment of type III acromioclavicular dislocation: Bosworth technique versus hook plating.

Objective: In this study, it was compared the clinical results of the Bosworth technique and hook plating in acromioclavicular (AC) dislocations.

Methods: 44 patients are retrospectively evaluated in this study whom diagnosed as type III AC dislocations and treated by two different surgical methods in two different clinics. The patients were 30 males and 14 females with a mean age of 44 years (range, 18-80 years).

Can a Biodegradable Implanted Bilayered Drug Delivery System Loaded with BMP-2/BMP-12 Take an Effective Role in the Biological Repair Process of Bone-Tendon Injuries? A Preliminary Report.

Background: Use of biodegradable and biocompatible materials in the orthopedic surgery is gaining popularity. In this research, the rate of controlled release of a bilayered prototype biomaterial designed to promote osteoblastic and tenoblastic activity was calculated using pharmacochemical methods.

Methods: The first part of the design, composed of a sodium tetraborate, polyvinyl alcohol, and starch based hydrogel, was loaded with bone morphogenic protein-2.

Upper eyelid angiolipoma associated friction in the glide zone.

A 74-year-old man was examined for a mass in the left upper eyelid. It was inconspicuous in inspection. There was no visual restriction, however a feeling of friction on the superior orbit during lid movement.
