Background: Acetabular chondrolabral delamination (ACD) is one of the most common hip cartilage injuries. However, there are very limited clinical treatments for this injury. Purpose: To evaluate effectiveness poly (lactic-co-glycolic acid) (PLGA) conical nail fixation in treatment acute and chronic ACD a porcine model. Study Design: Controlled laboratory study. Methods: In study, 24 pigs underwent surgically induced junction. Pigs were randomly divided into 3 groups: control group...
Abstract Purpose: To determine the correlation and classification consistency of femoral version measurements between magnetic resonance (MR) computed tomography (CT) using 4 commonly used measurement methods. Method: A retrospective study was performed on patients with femoroacetabular impingement (FAI) who received preoperative CT MR imaging assessment surgical hip ipsilateral distal femur. Femoral measured Murphy method, oblique Reikerås Lee method. Intra- inter-rater agreements were...
Abstract Hip dysplasia is a developmental disorder that resulted in insufficient acetabular coverage. Current surgical treatments are technically demanding, complex, invasive, and often lead to associated complications. Therefore, the development of regenerative implants fit bone induce osteogenesis chondrogenesis high demand. In this study, an implant was developed which osteogenic part 3D printed using polycaprolactone (PCL), crosslinked with dopamine, subjected surface mineralization;...
Abstract Background: Recent studies have shown high expression levels of certain inflammatory, anabolic, and catabolic genes in the articular cartilage from impingement zone hips with femoroacetabular (FAI), representing an increased metabolic state. Nevertheless, little is known about molecular properties bone tissue FAI. Method: Bone samples patients early-stage cam-type FAI were collected during hip arthroscopy for treatment Control six who underwent total replacement because a femoral...
Abstract Purpose: The purposes of our study were 1) to investigate the potential change labral size after arthroscopic repair and 2) analyze relationship between acetabular functional outcomes. Methods: In this retrospective study, patients diagnosed with tear undergoing hip in institution September 2016 December 2018 included. Magnetic resonance imaging was obtained preoperatively postoperatively, length height measured three anatomic sites: 11:30, 1:30, 3:00 positions. All completed at...
Abstract Background: The surgical technique of femoroacetabular impingement (FAI) comorbided with borderline dysplasia the hip (BDDH) still remains controversial since prolong risk negative prognosis was brought up and necessity management emphasized. purpose this study to evaluate clinical outcomes a new arthroscopic capsular suture-lifting in treatment patients FAI BDDH. Hypothesis: We hypothesized that could achieve better anterior stability be observed. Methods: evaluated consecutive who...
Rotator cuff tear (RCT) is a prevalent shoulder injury that poses challenges for achieving continuous and functional regeneration of the tendon-to-bone interface (TBI). In this study, we controlled delivery growth factors (GFs) from liposomal nanohybrid cerasomes by ultrasound implanted three-dimensional printed polycaprolactone (PCL) scaffolds modified with polydopamine loaded bone marrow mesenchymal stem cells (BMSCs) to repair tears infraspinatus tendon in lapine model. Direct suturing...
Background: Unlike the adult meniscus, fetal meniscus possesses robust healing capacity. The dense and stiff matrix of provides a biophysical barrier for cell migration, which is not present in meniscus. Inspired by developmental characteristics, modifying into fetal-like, loose soft microenvironment holds opportunity to facilitate repair, especially avascular zone. Hypothesis: Modifying could enhance migration tear interface subsequent Study Design: Controlled laboratory study. Methods:...
The options for surgical treatment of an anterior labrum lesion have become extensive. Arthroscopic treatments are widely used as improved minimally invasive option with a quick recovery. the glenoid generally requires creation two working portals. However, arthroscopic through single portal is still successful. Our single-portal technique avoids interference between instruments inserted portals and minimizes postoperative scarring, pain, reduction in range motion. purpose this article was...
Background: Rotator cuff tears have been repaired using the transosseous method for decades. The direct suture (DS) technique has widely used rotator tears; however, retear rate is relatively high. Suture anchors are now frequently repair (RCR) in accordance with recent developments materials. However, polyether ether ketone (PEEK) may still cause complications such as formation of cysts and osteophytes. Some studies developed inlay (IS) RCR. Purpose/Hypothesis: To compare how 3 different...
There is a lack of validated small animal models for femoroacetabular impingement (FAI) that induce intra-articular lesions and cause osteoarthritis (OA) progression. The gene expression profile articular cartilage in patients with FAI has not been characterized studies. purpose this study to describe novel rabbit model induction OA progression characterize the pattern impinged using model. Thirty 6-month-old New Zealand White rabbits underwent unilateral endobutton implant placement at...
ABSTRACT Objectives To describe the incidences of injuries and illnesses sustained during XXIV Winter Olympic Games, hosted by Beijing in 2022. Methods We recorded daily number athletes nonathletes polyclinic medical venues documented 2022 staff. Results In total, 35,537 were evaluated for illnesses. The staff reported 725 1119 comprising 24 31 per 1000 Games. Altogether, 2.4% incurred at least one injury 3.1% had illness. incidence was highest (14.4%), team officials (8.8%), (2.1%),...
