Long-term Follow-up Results of Femoral Revision Hip Arthroplasty Using Impaction Bone Grafting and Standard Cemented Polished Stem.

Background: To report the long-term clinical and radiologic results of impaction bone grafting and standard cemented polished stem for femoral revision arthroplasty in patients with extensive bone deficiency.

Methods: We retrospectively reviewed 47 hips that underwent femoral revision hip arthroplasty using an impaction-morselized allograft with a standard cemented polished stem. The average age at the time of revision hip arthroplasty was 55 years (range, 39-75 years).

Simple Minimally Invasive Method to Reduce Valgus-Impacted and Tilted Femoral Neck Fractures without Soft Tissue or Cartilage Injury: Radiological and Clinical Results.

Objective: This is a rare study comparing the radiological and functional outcomes of fixation after reduction with in situ fixation group using Femoral Neck System (FNS). The aim of this study was to introduce a simple, innovative, minimally invasive method to reduce valgus-impacted and tilted femoral neck fractures without soft tissue or cartilage injury.

Methods: A retrospective comparative analysis of 46 patients between May 2020 and February 2022 was performed.

Tibial Tubercle Osteotomy vs the Extensile Medial Parapatellar Approach in Revision Total Knee Arthroplasty: Is Tibial Tubercle Osteotomy a Harmful Approach?

Background: As the frequency of total knee arthroplasty (TKA) is increasing, long-term follow-up of patients has become essential, and the frequency of revision total knee arthroplasty (R-TKA) due to the occurrence of various complications has also increased. There is controversy regarding which approach has minimal complications and an adequate visual field in R-TKA. Therefore, we compared the clinical and radiological results between the extensile medial parapatellar (EMP) approach and tibial tubercle osteotomy (TTO) for R-TKA.

Outcomes of Cephalomedullary Nailing in Basicervical Fracture.

Purpose: A basicervical femoral fracture is defined as a fracture of base of neck of femur that occurs medially from intertrochanteric line above lesser trochanter. In this study, we intended to evaluate radiological and clinical results of basicervical femoral fractures treated by intramedullary nailing.

Materials And Methods: Fifteen patients, who underwent intramedullary nailing among 50 patients, out of 50 who were diagnosed with basicervical femoral fractures from July 2012 to May 2015 were studied.

Is the arthroscopic suture bridge technique suitable for full-thickness rotator cuff tears of any size?

Purpose: The purpose of this study was to compare functional outcomes and tendon integrity between the suture bridge and modified tension band techniques for arthroscopic rotator cuff repair.

Methods: A consecutive series of 128 patients who underwent the modified tension band (MTB group; 69 patients) and suture bridge (SB group; 59 patients) techniques were enrolled. The pain visual analogue scale (VAS), Constant, and American Shoulder and Elbow Surgeons (ASES) scores were determined preoperatively and at the final follow-up.

The Fate of Allogeneic Femoral Head Bone Grafts Using Varus-Valgus Constrained Total Knee Arthroplasty in Neuropathic Joints.

Background: This study was conducted to assess the clinical and radiological results of total knee arthroplasty (TKA) with an allogeneic bone graft using varus-valgus constrained (VVC) prostheses in knees with severe bone defects and unstable neuropathy.

Methods: This study included 20 knees of 16 patients who underwent TKA between August 2001 and January 2006 due to unstable knees with severe bone destruction resulting from neuropathic arthritis. At the time of surgery, the mean age of the patients was 56 years.

Is the arthroscopic modified tension band suture technique suitable for all full-thickness rotator cuff tears?

Background: We aimed to identify the clinical and structural outcomes after arthroscopic repair of full-thickness rotator cuff tears of all sizes with a modified tension band suture technique.

Methods: Among 63 patients who underwent arthroscopic rotator cuff repair for a full-thickness rotator cuff tear with the modified tension band suture technique at a single hospital between July 2011 and March 2013, 47 were enrolled in this study. The mean follow-up period was 29 months.

Primary Aneurysmal Bone Cyst in the Iliac Bone: A Case Report.

Symptomatic aneurysmal bone cysts with expansible lesions in the pelvis are rare in children. The management of an aggressive vascular lesion in a female child is challenging. The standard treatment for aneurysmal bone cysts is accompanied by a high risk of local recurrence.

Aggravation of inflammatory response by costimulation with titanium particles and mechanical perturbations in osteoblast- and macrophage-like cells.

The interface between bone tissue and metal implants undergoes various types of mechanical loading, such as strain, compression, fluid pressure, and shear stress, from daily activities. Such mechanical perturbations create suboptimal environments at the host bone-implant junction, causing an accumulation of wear particles and debilitating osseous integration, potentially leading to implant failure. While many studies have focused on the effect of particles on macrophages or osteoprogenitor cells, differential and combined effects of mechanical perturbations and particles on such cell types have not been extensively studied.

Arthroscopic treatment of lateral epicondylitis: comparison of the outcome of ECRB release with and without decortication.

Purpose: The purpose of this study was to compare the early clinical results of arthroscopic extensor carpi radialis brevis (ECRB) release with and without bone decortication in the treatment of lateral epicondylitis.

Materials And Methods: Thirty-eight patients who were surgically treated for lateral epicondylitis between 2004 and 2008 were included in this retrospective review. Among these 38 patients, 19 underwent arthroscopic ECRB release and 19 patients underwent both ECRB release with decortication of the lateral epicondyle.

Induction and localization of NOD2 protein in human endothelial cells.

NOD2 is mainly expressed in human monocytes/macrophages and intestinal epithelial cells and has been speculated to play in gut physiology. However, whether NOD2 is expressed in vascular endothelium is not currently determined. Human umbilical vascular endothelial cells (HUVECs) minimally expressed NOD2 gene, whereas stimulation of HUVEC with bacterial LPS, IL-1beta, or TNF-alpha resulted in significant up-regulation of NOD2.
