BACKGROUND: Periprosthetic tissue cultures, sonication and synovial fluid cultures remain the gold standard for prosthetic joint infection (PJI) diagnosis. However, some 15-20% culture-negative PJI are still reported. Therefore, there is the need for other diagnostic criteria. One point of concern relative to the different definitions of PJI is as to the inclusion of the c-reactive protein (CRP) and the erythrocyte sedimentation rate (ESR) as diagnostic criteria for PJI despite them being non-specific inflammatory blood tests...

PURPOSE: The aim of this study is to examine the capacity of muscle tissue preserved on hamstring tendons forming candy-stripe grafts in order to improve tendon to bone ingrowth and ligamentization. We hypothesized that muscle tissue does possess a stem cell population that could enhance the healing process of the ACL graft when preserved on the tendons. METHODS: Human samples from gracilis and semitendinosus muscles were collected during ACL surgery from ten patients and from these tissue samples human muscle-derived stem cells and tendon-derived stem cells were isolated and propagated...

PURPOSE: The glycosaminoglycan (GAG) chemical exchange saturation transfer (CEST) imaging method (gagCEST) makes it possible to assess and quantify the GAG concentration in human cartilage. This biochemical imaging technique facilitates detection of the loss of GAG in the course of osteoarthritis. The gagCEST technique was used to analyse the perilesional zone (PLZ) adjacent to repair tissue after cartilage repair surgery, to determine whether there are biochemical changes present in the sense of degeneration...

Elhadi Sariali, Yohan Knaffo
PURPOSE: The use of femoral stems with a short metaphyseal fixation may lead to fractures or subsidence. Such failures may be related to a mismatch between the torsions or the sagittal flares of the stem and the femur. The goal of our study was to perform a 3D analysis of the proximal metaphyseal femur anatomy with a special focus on the anterior proximal flare and torsion. Such data may help to detect the outlier patients for whom a short metaphyseal fixation should be avoided. METHODS: A prospective study included 80 consecutive patients who underwent a primary cementless THA with a 3D CT-scan based pre-operative planning...

Bin Song, Changchuan Li, Na Chen, Zhong Chen, Yan Zhang, Yunfeng Zhou, Weiping Li
PURPOSE: We introduced a new technique of all-arthroscopic anatomical anterior talofibular ligament (ATFL) reconstruction using semitendinosus autografts. METHODS: From June 2012 to June 2013, 28 patients with chronic ATFL rupture underwent arthroscopic anatomic reconstruction of the ATFL. They were divided into the Broström group (n = 16) and reconstruction group (n = 12). The American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue score (VAS) was recorded before the operation, 12 months after the operation and 30 months after the operation...

PURPOSE: Length of stay (LOS) is a major driver of cost and quality of care. A bundled payment system makes it essential for orthopaedic surgeons to understand factors that increase a patient's LOS. Yet, minimal data regarding predictors of LOS currently exist. Using the ACS-NSQIP database, this is the first study to identify risk factors for increased LOS for orthopaedic trauma patients and create a personalized LOS calculator. METHODS: All orthopaedic trauma surgery between 2006 and 2013 were identified from the ACS-NSQIP database using CPT codes...

Jason E Hsu, Jeremy S Somerson, Kiet V Vo, Frederick A Matsen
PURPOSE: While as many as 50% of revision shoulder arthroplasties are culture positive, a consistent, clinically useful definition of a "periprosthetic shoulder infection" is lacking. We conducted a systematic review of the published literature with respect to (1) the definition of a "periprosthetic shoulder infection", (2) the pre-operative evaluation for possible infection, and (3) the harvesting and culturing of specimens at the time of surgical revision. METHODS: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we identified 20 studies concerning infection at the time of revision shoulder arthroplasty...

PURPOSE: Degenerative joint disease of the lumbar spine is a pervasive problem in healthcare; however, its aetiology and risk factors remain poorly defined. There have been recent attempts to correlate the anatomic parameters of facet angle and pelvic incidence with spine osteoarthritis, although data remains limited. The purpose of this experiment was to determine how age, gender, race, facet angle, tropism, and pelvic incidence correlate to facet joint osteoarthritis in the lumbar spine...

PURPOSE: Skeletal muscle injuries are commonly observed in sports and traumatology medicine. Previously, we demonstrated that transcutaneous application of carbon dioxide (CO2) to lower limbs increased the number of muscle mitochondria and promoted muscle endurance. Therefore, we aimed to investigate whether transcutaneous CO2 application could enhance recovery from muscle injury. METHODS: Tibialis anterior muscle damage was induced in 27 Sprague Dawley rats via intramuscular injection of bupivacaine...

BACKGROUND: The literature on ankle valgus development after procuring non-vascularised fibular grafts in children is still scanty. The non-vascularised fibular graft has distinction of fibular regeneration occurring at the donor site. MATERIAL AND METHODS: We retrospectively analysed the valgus deformities at the donor leg following harvest of non-vascularised fibular graft to determine the various contributing factors in growing children. All these patients had minimum two years post index procedure follow up...

PURPOSE: Laminectomy with lateral mass screw fixation has been proven to be an effective method to treat the multilevel cervical degenerative myelopathy and severe cervical spondylosis. However, accurate and safe insertion of the lateral mass screw is technically demanding due to the individual variations of the anatomy of the lateral mass of the subaxial cervical spine. Misplaced lateral mass screw is not uncommon, and operation-related complications still beset the surgeons, which may impair the clinical outcomes...
