Background: Treating symptomatic osteochondral defects is challenging, especially in young adults with deep (>8-10 mm) empty after osteochondritis dissecans (OCD) or collapsed condyles secondary to avascular necrosis (AVN). For this population, osteoarthritis (OA) inevitable if articular congruence not restored. Purpose: To describe the autologous chondrocyte implantation (ACI) “sandwich” technique bone grafting (ABG) and compare it ABG alone for restoration of unit. The midterm long-term...

Background: Symptomatic osteochondral defects are difficult to manage, especially in patients with deep (>8-10 mm) empty defects. The restoration of articular congruence is crucial avoid the progression osteoarthritis (OA). Purpose: To describe autologous chondrocyte implantation (ACI) “segmental-sandwich” technique for unit and evaluate midterm outcomes treated this procedure. Correlations between magnetic resonance imaging (MRI) radiographic findings were assessed. Study Design: Case...

Background: Treating bipolar chondral lesions in the tibiofemoral (TF) compartment with cartilage repair procedures is challenging, and a suitable treatment remains unclear. Purpose: To evaluate clinical outcomes after autologous chondrocyte implantation (ACI) for of TF compartment. Study Design: Case series; Level evidence, 4. Methods: We evaluated 57 patients who underwent ACI symptomatic by single surgeon between October 1995 June 2014. One patient did not return follow-up. Thus, 56 (58...

It is unknown how ketamine anesthesia immunologically affects the outcome of patients with postoperative septicemia. We investigated effects on mice an Escherichia coli or lipopolysaccharide (LPS) challenge after laparotomy, focusing phagocytosis by liver macrophages (Kupffer cells) and cytokine production.C57BL/6 received sevoflurane during which was followed E. LPS challenge; thereafter, mouse survival rates secretions were examined. The a β-adrenoceptor antagonist, nadolol, also assessed...

Phosphodiesterase (PDE)-3B, a major PDE isoform in adipocytes, plays pivotal role the antilipolytic action of insulin. Insulin-induced phosphorylation and activation PDE3B is phosphatidylinositol 3-kinase (PI3-K) Akt dependent, but precise mechanism not fully understood. We have identified 14-3-3 β, critical scaffolding molecule signal transduction, as protein that interacts with using yeast two-hybrid system. The interaction between β was then confirmed vitro. glutathione S-transferase...

While propofol has been well studied at the molecular and clinical level, less known about effects of level individual neurons local networks. We used Utah Electrode Arrays (UEAs) to investigate anesthesia on action potentials (APs) field (LFPs). UEAs were implanted into neocortex two humans three felines.

Meniscal injuries are a risk factor for osteoarthritis (OA). While mechanical pathway between meniscal injury and OA has been described, the biological effects of inflammation on this have yet to be clarified. The aim our study was compare levels specific inflammatory mediators, tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), nerve growth (NGF), in injured uninjured tissue related knee joint synovium. Tissue samples were obtained from 19 patients, 31.1 ± 13.6 years old, who...

Objective Osteochondral allograft transplantation (OCA) is a well-established procedure for patients with symptomatic cartilage defects in the knee. Revision to OCA after prior failed repair has shown similar clinical outcomes as primary OCA; however, most of procedures were arthroscopic smaller defects. There no literature investigating autologous chondrocyte implantation (ACI) treatment large chondral The purpose this study was therefore determine undergoing revision ACI compared matched...
