Patellar resurfacing in total knee arthroplasty (TKA) remains controversial. This study evaluates the results of resurfacing and non-resurfacing of the patella. Fifty-six patients with osteoarthritis (OA) of the knee were enrolled in a prospective randomised clinical trial using a posterior-stabilised TKA. Evaluations were done preoperatively and after 1, 3, 6, 12 and 24 months. Disease specifi...

CONTEXT There is uncertainty regarding the oncologic effectiveness of kidney-sparing surgery (KSS) compared with radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). OBJECTIVE To systematically review the current literature comparing oncologic outcomes of KSS versus RNU for UTUC. EVIDENCE ACQUISITION A computerised bibliographic search of the Medline, Embase, and Co...

Introduction Herein, we describe the interesting case of a 13-year-old female with Kearns-Sayre syndrome (KSS) who underwent a successful T3 ~ L3 posterior spinal instrumentation and fusion (PSIF). KSS is a rare mitochondrial myopathy with only 226 cases reported in published literature as of 1992. It is the result of deletions in mitochondrial DNA and manifests as a triad of: 1) chronic progre...

In the typical Web applications each intelligent database agent can be defined as a Knowledge system (KS) with a global ontology, which integrates a number of source data distributed in Web by traditional extensional mappings, and must be robust enough in order to take in account the incomplete and locally inconsistent information of its sources. The traditional extensional semantics for mappin...

The goal of the research presented in this paper was to study a new software paradigm ± adaptive software ± in which the structure of an adaptive program is patterned upon the structure of an adaptive controller. Towards this aim, we implemented a domain-speci®c (object/target recognition) program (A Recon®gurable Architecture for Adapting to Changes in the Requirements (RAACR)) that can adapt ...
