Partial lateral facetectomy plus Insall’s procedure for the treatment of isolated patellofemoral osteoarthritis: survival analysis
Conclusion The treatment for isolated patellofemoral osteoarthritis through partial lateral facetectomy and Insall’s procedure demonstrated good long-term survival. The presence of preoperative medial tibiofemoral pain, genu flexum, and incipient tibiofemoral osteoarthritis increased the risk of failure of this procedure. In contrast, higher anatomical and total KSS scores, absence of knee effusion, higher value of the Caton–Deschamps index, and lateral position of the patella were found to protect against failure. Level of evidence Prospective case series, Level IV. Content Typ...

Is mortality after hip fracture associated with surgical delay or admission during weekends and public holidays?
Abstract Background and purpose Hip fractures are associated with high mortality, but the cause of this is still not entirely clear. We investigated the effect of surgical delay, weekends, holidays, and time of day admission on mortality in hip fracture patients. Patients and methods Using data from the Danish National Indicator Project, we identified 38,020 patients admitted from 2003 to 2010. Logistic regression analysis was used to study the association between sex, age, weekend or holiday admission, night-time admission, time to surgery, and ASA score on the one hand and mortality on the other. Results The ri...

More accurate component alignment in navigated total knee arthroplasty has no clinical benefit at 5-year follow-up.
Abstract Background and purpose Computer navigation in total knee arthroplasty is somewhat controversial. We have previously shown that femoral component positioning is more accurate with computed navigation than with conventional implantation techniques, but the clinical impact of this is unknown. We now report the 5-year outcome of our previously reported 2-year outcome study. Methods 78 of initially 84 patients (80 of 86 knees) were clinically and radiographically reassessed 5 (5.1-5.9) years after conventional, image-based, and image-free total knee arthroplasty. The methodology was identical to that used preo...

Screening for osteoporosis reduced new fracture incidence by almost half.
Abstract Background and purpose Fractures can be prevented if osteoporosis is identified and treated. In 2002, we initiated a screening program at our orthopedics department, in which patients between 50 and 75 years of age with a wrist, shoulder, vertebral, or hip fracture are assessed by DEXA of the hip and spine and encouraged to see their doctor for decision on treatment regarding osteoporosis. The patients receive written documents containing information, DEXA results, and a letter to their doctor with suggestions regarding blood tests and treatment. In this 6-year follow-up study, we compared the fracture rec...

Periprosthetic Vancouver type B1 and C fractures treated by locking-plate osteosynthesis.
Abstract Background and purpose Historically, the treatment of periprosthetic femoral fractures (PFFs) has been associated with a high frequency of complications and reoperations. The preferred treatment is internal fixation, a revision of the femoral stem, or a combination of both. An improved understanding of plate use during internal fixation, and the introduction of locking-plate osteosynthesis may lead to improved outcome. We evaluated the outcome of Vancouver type B1 and C PFFs treated by locking-plate osteosynthesis, by assessing rates of fracture union and reoperations and by analyzing failure cases. Patie...

A computational framework for investigating the positional stability of aortic endografts.
Abstract Endovascular aneurysm repair (Greenhalgh in N Engl J Med 362(20):1863-1871, 2010) techniques have revolutionized the treatment of thoracic and abdominal aortic aneurysm disease, greatly reducing the perioperative mortality and morbidity associated with open surgical repair techniques. However, EVAR is not free of important complications such as late device migration, endoleak formation and fracture of device components that may result in adverse events such as aneurysm enlargement, need for long-term imaging surveillance and secondary interventions or even death. These complications result from the device ...

Chondromodulin‐I derived from the inner meniscus prevents endothelial cell proliferation
In this study, we demonstrated that the inner meniscus contained larger amounts of ChM‐I, and that the inner meniscus‐derived ChM‐I inhibited endothelial cell proliferation. Our results suggest that ChM‐I may be a key anti‐angiogenic factor for maintaining the avascularity of the inner meniscus. © 2012 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

The talar axis–first metatarsal base angle in CVT treatment: a comparison of idiopathic and non-idiopathic cases treated with the Dobbs method
Conclusion In our series, the success of the Dobbs method in CVT treatment depended on the flexibility in the talonavicular complex. The TAMBA value and TAMBA difference (TAMBA neutral minus TAMBA plantarflexion) express the flexibility in the talonavicular joint and could be predictive for the success of a minimally invasive treatment. Only in a few cases is the success of the Dobbs method limited. These feet are associated with a TAMBA greater than 120° in neutral position and, particularly, a TAMBA difference smaller than 25°.

Human cartilage fragments in a composite scaffold for single-stage cartilage repair: an in vitro study of the chondrocyte migration and the influence of TGF-β1 and G-CSF
Conclusion Outgrowing cells may represent a subset of chondrocytes undergoing a phenotypic shift towards a proliferative state. TGF-β1, and to a greater extent G-CSF, may accelerate this outgrowth. The clinical relevance of this study may involve a potential future clinical application of scaffolds preloaded with growth factors as an additional coating for chondral fragments. Indeed, a controlled delivery of G-CSF, widely employed in various clinical settings, might improve the repair process driven by minced human cartilage fragments during one-stage cartilage repair.

Finite element analysis to determine stress fields at the apex of V-Y flaps
Abstract After performing a V-Y advancement flap, we observed an unusually shaped necrosis, resembling a keyhole at the apex of the flap. As high closing tensions are an accepted cause of skin necrosis, we developed a mathematical model based on the finite element analysis in order to determine the stress field by simulating the mechanical behavior of human skin during suture and to explain this particular shape of necrosis. For the modeling, a planar nonlinear two-dimensional finite element model was used. The numerical simulation was carried out with Ansys® v12 software. Results are expressed in numerical...

Return to sport following anterior cruciate ligament reconstruction
Abstract Rates of return to pre-injury sport following anterior cruciate ligament (ACL) reconstruction are less than might be expected from standard outcome measures and there appears to be a rapid decline in sporting participation after two to three years. There are many factors that influence whether an individual will return to sport following this type of surgery. They include not only surgical details and rehabilitation, but also social and psychological factors, as well as demographic characteristics. Age is of particular importance with older patients being less likely to resume their pre-injury sport...

A genome-wide sib-pair linkage analysis of ossification of the posterior longitudinal ligament of the spine
Abstract Ossification of the posterior longitudinal ligament of the spine (OPLL) is a common musculoskeletal disease among people after middle age. The OPLL presents with serious neurological abnormalities due to compression of the spinal cord and nerve roots. The OPLL is caused by genetic and environment factors; however, its etiology and pathogenesis still remain to be elucidated. To determine the susceptibility loci for OPLL, we performed a genome-wide linkage study using 214 affected sib-pairs of Japanese. In stratification analyses for definite cervical OPLL, we found loci with suggestive linkage on 1p2...

Psychiatric disorders in patients suffering from an acute cerebrovascular accident or traumatic injury, and their effects on rehabilitation: an observational study.
CONCLUSION: History of psychiatric disorders is the most relevant factor associated with psychopathology in patients with an acute cerebrovascular accident or traumatic injury, followed by lower total FIM scores, and type of pathologic event. CLINICAL REHABILITATION IMPACT: The presence of psychiatric disorders may potentially influence the rehabilitation process and outcomes; thus their recognition and management are key factors during a rehabilitation program.

Evaluation of a single preoperative dose of etoricoxib for postoperative pain relief in therapeutic knee arthroscopy.
Abstract Background and purpose Analgesics can have undesirable effects. We assessed whether a single preoperative dose of 120 mg etoricoxib reduces the need for additional opioids after therapeutic arthroscopic knee surgery. Methods A double-blind, placebo-controlled study was performed at a single center. 66 patients scheduled to undergo elective therapeutic knee arthroscopy were included. They were randomly selected to be given either 120 mg of etoricoxib (n = 33) or placebo (n = 33) 1 hour before induction of general anesthesia. A patient-controlled analgesia device was used postoperatively. We recorded total...

Early migration of tibial components is associated with late revision.
Abstract Purpose We performed two parallel systematic reviews and meta-analyses to determine the association between early migration of tibial components and late aseptic revision. Methods One review comprised early migration data from radiostereometric analysis (RSA) studies, while the other focused on revision rates for aseptic loosening from long-term survival studies. Thresholds for acceptable and unacceptable migration were determined according to that of several national joint registries: < 5% revision at 10 years. Results Following an elaborate literature search, 50 studies (involving 847 total knee pro...

Metal-on-metal joint bearings and hematopoetic malignancy.
Abstract Abstract This is a review of the hip arthroplasty era. We concentrate on new metal bearings, surface replacements, and the lessons not learned, and we highlight recent reports on malignancies and joint implants. A low incidence of blood malignancies has been found in bone marrow taken at prosthetic surgery. The incidence is increased after replacement with knee implants that release very low systemic levels of metal ions. A carcinogenic effect of the high levels of metal ions released by large metal-on-metal implants cannot be excluded. Ongoing Swedish implant registry studies going back to 1975 can serve ...

Patient-related risk factors for fracture-healing complications in the United Kingdom General Practice Research Database.
Abstract Background and purpose A variety of risk factors have been hypothesized to contribute to the development of fracture-healing complications; however, population-based estimates of the strength of these risk factors are limited. In this case-control study, we evaluated patient-related risk factors for fracture-healing complications. Methods Using the United Kingdom General Practice Research Database, we identified patients with a fracture-healing complication (delayed union, nonunion, or malunion) between 1988 and 2008. 4 controls (i.e. patients with normal healing) were matched to each case on general prac...

“Everybody feels a broken bone, but only we can feel a broken heart”: Group membership influences the perception of targets' suffering
Abstract There is surmounting evidence in the literature demonstrating that social pain (e.g. rejection, humiliation, and isolation) and physical pain (e.g. injury or assault) overlap in personal experiences. The present investigation focuses on second‐hand perceptions of social and physical pain. We argue that judgments of others' pain may vary as a function of group membership. By integrating research on intergroup bias in pain judgment with intergroup attributions of humanity, we predicted that observers tend to underestimate social pain more than physical pain in out‐groups compared with in‐groups. Across two stu...
