Background: Intense exercise has been reported as one risk factor for hip and knee osteoarthritis (OA). Purpose: This study aimed to evaluate (1) whether this is true both former impact nonimpact athletes, (2) if the of a or arthroplasty due OA higher than expected, (3) joint deterioration associated with injuries. Study Design: Cohort study; Level evidence, 3. Methods: The prevalence in were registered 709 male elite athletes median age 70 years (range, 50-93 years), retired from sports 35...

Physical activity is favorable for peak bone mass but if the skeletal benefits remain and influence fracture risk in old age debated. In a cross‐sectional controlled mixed model design, we compared dual X ‐ray absorptiometry‐derived mineral density ( BMD ) size 193 active retired male elite soccer players 280 controls, with duplicate measurements of same individual done mean 5 years apart. To evaluate lifetime fractures, used retrospective study design 397 1368 controls. Differences traits...

To enable objective measurements of weight bearing in hip replacement patients a portable instrument set-up with an on-line registering pressure-sensitive insole was developed. Six men and 9 women, median age 58 (48-67) years, who had been operated on cementless or hybrid arthroplasty were studied. All independent functional. A physiotherapist instructed the to use crutches order support 30% their body weight. The then walked standardized distance over five different types terrain: level,...

Abstract A fracture in childhood is associated with low bone mineral density (BMD), but it debated whether a at growth also predicts BMD young adulthood. The purpose of this work was to gender-specifically evaluate children are increased risk Distal forearm (g/cm2) measured single-photon absorptiometry (SPA) 47 boys and 26 girls (mean age 10 years, range 3–16 years) an index 41 43 4–16 no fracture. re-measured mean 27 years later the same SPA apparatus dual-energy (DXA), quantitative...

Physical activity during growth is associated with high peak bone mass and may, as a result, prevent osteoporosis later in life. It therefore possible that athletic youth could lower the risk of fragility fractures old age. Although this currently unclear based on evaluations surrogate skeletal end point variables former athletes, we hypothesized not case.In retrospective matched controlled cohort study design, calculated lifetime incidence from results mailed questionnaire sent to 709 male...

Background and purpose — There is an ongoing debate regarding the appropriate level of constraint in primary TKA.To provide increased stability better kinematics, more resembling a natural knee, medial congruent (MC) tibial insert has been introduced. To investigate potential impact on implant migration, we evaluated cemented Persona TKA, randomizing between MC cruciate-retaining (CR) designs. Patients methods 60 patients with osteoarthritis were randomized to either CR or component....

Programs referred to as Fast-Track/Rapid Recovery/Enhanced Recovery After Surgery have proven both effective and safe in joint replacement surgery, the degree where same-day discharge (SDD) has been attempted carefully selected cases at specialized outpatient units. Therefore, primary aim of this study was evaluate a surgery protocol regarding safety using minor partial knee (PKR) procedure by non-selectively recruiting patients public hospital for one consecutive year.33 unselected PKR were...

Purpose Total knee arthroplasty (TKA) and unicompartmental (UKA) are both considered suitable for antero-medial osteoarthritis spontaneous osteonecrosis of the knee. National registry data consistent in showing higher revision rates UKA. Adequately adjusted, these findings may be challenged by differences adverse events patient-reported outcomes, as can have serious long-term implications. Based on preoperative radiographs, aim was to retrospectively compare two principle surgeries respects....
