BACKGROUND The purpose of the present study was to compare the clinical results of 3 posterior cruciate ligament reconstruction techniques according to the time from injury to surgery and remnant PCL status and to evaluate the efficiency of each technique. METHODS The records of 89 patients who underwent primary PCL reconstructions with a posterolateral corner sling were analyzed retrospectiv...

BACKGROUND Posterior cruciate ligament (PCL) reconstructions are rarely performed compared with that for the anterior cruciate ligament (ACL). PURPOSE To evaluate the clinical and functional outcome after isolated or multiligament PCL reconstruction. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients who underwent PCL reconstruction between 2002 and 2010 were included. Stan...

BACKGROUND AND PURPOSE The purpose of this study was to assess the effect of postcontrast CT (PCCT) leakage (PCL) on hematoma growth in CTA spot negative patients. METHODS A retrospective study of 61 patients presenting within 6 hours of primary ICH onset imaged with CT angiography (CTA) and PCCT. Presence of CTA spot sign and PCL were documented. PCL was defined as the presence of contrast e...

BACKGROUND Research conducted with forensic psychiatric patients found moderate correlations between violence in institutions and psychopathy. It is unclear though, whether the PCL-R is an accurate instrument for predicting aggressive behavior in prisons. Results seem to indicate that the instrument is better suited for predicting verbal rather than physical aggression of prison inmates. METH...

Asymmetric telechelic α-hydroxyl-ω-(carboxylic acid)-poly(ε-caprolactone) (HA-PCL), α-hydroxyl-ω-(benzylic ester)-poly(ε-caprolactone) (HBz-PCL) and an asymmetric telechelic copolymer α-hydroxyl-ω-(carboxylic acid)-poly(ε-caprolactone-co-γbutyrolactone) (HA-PCB) were synthesized by ring-opening polymerization of εcaprolactone (CL). CL and CL/γ-butyrolactone mixture were used to obtain homopolym...

For successful bone tissue engineering, a scaffold needs to be osteoconductive, porous, and biodegradable, thus able to support attachment and proliferation of bone cells and guide bone formation. Recently, hydroxyapatites (HA), a major inorganic component of natural bone, and biodegrade polymers have drawn much attention as bone scaffolds. The present study was designed to investigate whether ...

BACKGROUND Lesser metatarsophalangeal joint (MTPJ) instability is a common complaint. The role each of the collateral structures play in maintaining joint stability is unknown. METHODS Twenty-six fresh-frozen cadaver lesser MTPJ's were tested for instability with the amount of force necessary to translate the joint 3 mm dorsally. Specimens were tested with 1) intact collateral ligaments, 2) t...

For most tissue engineering applications, surface modification and sterilization of polymers are critical aspects determining the implant success. The first part of this study is thus dedicated to modifying polycaprolactone (PCL) surfaces via plasma treatment using a medium pressure dielectric barrier discharge, while the second part focuses on the sterilization of plasma-modified PCL. Chemical...

BACKGROUND Long-term patency of conventional synthetic grafts is unsatisfactory below a 6-mm internal diameter. Poly(epsilon-caprolactone) (PCL) is a promising biodegradable polymer with a longer degradation time. We aimed to evaluate in vivo healing and degradation characteristics of small-diameter vascular grafts made of PCL nanofibers compared with expanded polytetrafluoroethylene (ePTFE) gr...
