A technique for producing controlled interconnected porous structures for application as a tissue engineering scaffold is presented in this article. The technique is based on the fabrication of a template of interconnected poly(ethyl methacrylate) (PEMA) microspheres, the introduction of a biodegradable polymer, poly-epsilon-caprolactone (PCL), and the elimination of the template by a selective...

The purpose of this study was to document the pattern ligament and meniscal injuries that occur with proximal tibia fractures due high energy trauma. Seventy patients high-energy mechanisms were evaluated magnetic resonance imaging (MRI) knee. All studies reported by a single musculoskeletal radiologist who blinded surgical physical findings. Of 70 patients, there 42 AO/OTA type 41B2 (60%) frac...

Background: Tibial eminence fractures account for up to 5% of knee injuries with an effusion in the pediatric population. Displaced require reduction and operative fixation via arthroscopic or open techniques. Indications: Arthroscopic suture screw are 2 most commonly described techniques tibial fracture treatment. We describe our preferred technique given versatility this decreased risks hardw...

Background: The short-time creep behavior for a series of biodegradable nanocomposites which is used as implantable device into body is a crucial factor. In the current paper, we aimed to study the effect of bioactive glass nanoparticles (BGn) on creep and creep-recovery behaviors of PLA/PCL blends at different given load and different applied temperatures. Method: A series of biodegradab...

OBJECTIVE The aim of the study was to: 1) evaluate the differences in pre-post operative knee functioning, mechanical stability, isokinetic knee muscle strength in simultaneous arthroscopic patients after having undergone an anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) with hamstring tendons reconstruction, 2) compare the results of ACL/PCL patients with the contro...

a 25 year-old man presented with pain, swelling, and intermittent drainage from distal lateral aspect of his left knee three months after undergoing isolated acl reconstruction with arthroscopic hamstring autograft and endobottom technique. his surgeon at that time tried to eliminate the pathology through arthroscopic wash out in two attempts. however, the pain, edema, and discharge recurred af...

Abstract Background Several studies on the relationship between morphological parameters and traumatic diseases of knee have already been conducted. However, few focused association morphology posterior cruciate ligament (PCL) avulsion fracture in adults. The objective this study was to evaluate impact PCL fracture. Methods 76 patients (comprised 40 men 36 women) with age- sex-matched controls ...

A novel method for the preparation of solvent-free poly(«-caprolactone) (PCL) microspheres from PCL/poly(ethylene glycol) (PEG) blends was developed and demonstrated. The particle size of the PCL spheres are in the range of 1 to 20 mm (mostly in the range 5–10 mm). The influences of the molecular weight of PCL, the molecular weight of PEG, the type of emulsifier, the concentration of plasticize...
