PURPOSE: Revision total hip arthroplasty (THA) is associated with increased rates of dislocation in obese patients. It is not known whether dual-mobility implants decrease dislocation in these patients with obesity. METHODS: We retrospectively reviewed two groups of revision THAs to compare the dislocation rate between 32 obese patients (BMI >30 kg/m(2)) with standard cups, and 35 obese patients (BMI >30 kg/m(2)) with dual-mobility cups. All patients received the same implants except for diameter head (32-mm head with standard cups and 28-mm head with dual mobility) and had the same cemented stem that was not changed at revision...

PURPOSE: The medial plica (MP) is a normal anatomic structure consisting of a fold in the synovial layer of the joint. Arthroscopic resection is currently used as a gold standard procedure in patients with medial plica syndrome (MPS), but there are few prospective studies that analyze the long-term functional outcomes of plica resection. METHODS: The purpose of this prospective study was to evaluate the long-term results of arthroscopic resection of the medial plicae of the knee...

The potential advantages of contemporary MoM THA implants include less volumetric wear with subsequent reduction of polyethylene wear-induced osteolysis and greater component stability with use of large-diameter femoral heads. However, there have been concerns regarding significantly elevated revision rates in MoM THA due to MoM-related complications such as adverse local tissue reaction (pseudotumour) formation. The increased failure rate in MoM hip arthroplasty is associated with the generation of biologically active, nanometer sized metal particles from the MoM bearing surfaces and taper junctions, which result in the development of a localized, adverse periprosthetic soft tissue response...

INTRODUCTION: Charcot arthropathy is a rare cause of debilitating joint destruction. Shoulder arthroplasty for Charcot arthropathy is challenging secondary to local bone and soft tissue loss, lack of protective sensation, and altered muscle control. The purpose of this study is to review the outcomes, complications, and survivorship of shoulder arthroplasty for Charcot arthropathy. METHODS: Between January 2000 and December 2011, ten shoulders with Charcot arthropathy were treated with shoulder arthroplasty at our Institution (six hemiarthroplasty, one total shoulder arthroplasty, three reverse shoulder arthroplasty)...

PURPOSE: Deformation of the talus in idiopathic congenital clubfeet is a known problem after treatment. However evidence on types of talus deformation and clinical relevance is rare. The aims of this study were first to define different types of talus deformation, and second, to evaluate the impact of these types on long-term results. METHODS: At a minimum follow-up of ten years 40 idiopathic clubfeet treated by a modified dorsomedial release were analyzed. Based on morphological appearance and the widened range of radius to length ratios (R/L-ratio) in treated clubfeet deformed tali were divided into two groups: tali with decreased R/L-ratios were classified as small-dome talus deformation (SD), tali with increased R/L-ratios were classified as flat-top talus deformation (FT)...

PURPOSE: Intramedullary and extramedullary fixation methods are widely used to treat unstable femoral intertrochanteric fractures, but the optimal surgical method remains controversial. The aim of this study was to estimate the outcomes of intramedullary fixation versus extramedullary fixation in treating unstable femoral intertrochanteric fractures. METHODS: Electronic literature databases were used for searching including MEDLINE (Ovid interface), EMBASE (Ovid interface) and the Cochrane Central Register of Controlled Trials (CENTRAL) (Wiley Online Library) (up to March 30, 2016)...

PURPOSE: Total ankle arthroplasty (TAA) and ankle arthrodesis (AA) are the main surgical treatment options for end-stage ankle arthritis. Although the superiority of each modality remains debated, there remains a lack of high-quality evidence-based studies, such as randomized controlled clinical trials, and meta-analyses of comparative studies. We performed a meta-analysis of comparative studies to determine whether there is a significant difference between these two procedures in terms of (i) clinical scores and patient satisfaction, (ii) re-operations, and (iii) complications...

Paul of Aegina lived in a era when the preservation of the ancient Greek tradition was for him almost a necessity. Eager to follow the dogma of "oρθoπo(ε)δώ" (orthopodo: pace with no malformation), he introduced a series of surgical operations of reconstructive-cosmetic-plastic-orthopaedic nature to confront any disfiguration of the human body. The aim of our study is to present the atmosphere of the era concerning the congenital malformations, describe briefly Paul's contribution on classic orthopaedics and present his views on the preternatural fingers...

PURPOSE: Periprosthetic joint infection (PJI) continues to be a significant complication after total joint arthroplasty. Diagnosis of PJI can be challenging and elusive in the absence of a gold standard. This purpose of this article is to review the current evidence on the utility of serum and synovial fluid biomarkers to help aid in the diagnosis of PJI with focusing on synovial fluid alpha-defensin. METHODS: Articles and data for this review were identified by searches of PubMed and Ovid MEDLINE up to June 1, 2016...

PURPOSE: To present a hypothesis regarding the pathways of angiogenesis in primary versus secondary hip osteoarthritis (OA). METHODS: In synovial tissue samples provided by 57 consecutive patients who underwent hip arthroplasty, immunohistochemical examinations were performed using the following angiogenesis-related antibodies: VEGF-A, COX-2, maspin and the endothelial cells markers CD31 and CD105. The cases were divided into three categories: classic primary hip OA (group A; n = 16), rapidly destructive hip OA (group B; n = 24) and hip OA secondary to avascular osteonecrosis of the femoral head (group C; n = 17)...

PURPOSE: To propose and to assess the reproducibility of a new method (GO [glenoid orientation] index) for the estimation of the glenoid orientation in relation to the anterior surface of the glenoid. METHODS: This is a retrospective study on computed tomography (CT) scan. The GO index was defined as the angle formed by a line perpendicular to the tangent to the anterior surface of the scapula and the glenoid line (which is defined as the line connecting the anterior and the posterior rim of the glenoid)...

PURPOSE: Precise pre-tensioning protocol of the graft has not been determined in anterior cruciate ligament (ACL) reconstruction. The aims of this study are to measure the human autologous graft elongation, and to reveal what portion of the graft elongated greater after pre-tensioning in ACL reconstruction. METHODS: Twenty-four hamstring tendon grafts which were harvested from patients were included. A continuous load of 150 N was applied to the graft twice for 30 seconds each (150 N-1 minute), and the same loading was repeatedly applied (150 N-2 minute)...

PURPOSE: It is an established fact that post-operative (p.o.) soft-tissue swelling and lymphoedema after total knee arthroplasty (TKA) have a major influence on the p.o. early functional outcome. Kinesio taping has a proven clinical effect in increasing lymph drainage. Despite the decades of experience gained and the assumed positive effects, hardly any investigations have been conducted to date on the influence of Kinesio taping on the p.o. healing process after TKA. The objective of the present study was to test the hypothesis that Kinesio taping used as a lymph application leads to a reduction of p...

AIM: Computerized navigation of unicondylar knee arthroplasties (UKA) is not a widespread technique. The lifespan of a UKA depends on the quality of its implantation. We know that overcorrection leads to a rapid extension of the osteoarthritis to the opposite side of the knee and undercorrection to a rapid loosening or wear of the prosthesis. Because of these difficulties and following a long experience with navigation of total knee arthroplasties (TKA) and osteotomies around the knee, we began using navigation for revisions to TKA in 2003 and for UKAs in 2008...

BACKGROUND: Congenital femoral deficiency (CFD) is one of the most challenging and complex conditions for limb lengthening. We focused on the problem of hip instability during femoral lengthening because subluxation and dislocation are potentially catastrophic for hip function. METHODS: We assessed for hip stability in 69 children (91 femoral lengthenings) who had CFD Paley type 1a (43 children) and 1b (26 children). The mean age at first lengthening was 6.4 years...
