The effects of preoperative balance training on balance and functional outcome after total knee replacement: a randomized controlled trial.
2019
Objective: To assess the effects of preoperative balance training on the early postoperative balance and functional outcomes after total knee replacement surgery and to test whether an outpatient intervention may be as effective as a domiciliary intervention. Design: This is a three-arm randomized controlled trial. Setting: University hospital. Subjects: Eighty-six individuals were recruited. Seventy-seven were analysed, aged 72.1 (SD 7.6) years, of which 68% were women. Outcome measures: Overall state of balance, as measured with the Berg Balance Scale, and patient-perceived functionality, as measured with the Knee Injury and Osteoarthritis Outcome Score Function in Activities in Daily Liv…
Muscle strength and range of movement deficits 1 year after hip resurfacing surgery using posterior approach.
2009
The aim was to evaluate the effect of the posterior surgical approach on hip muscle strength and range of movement (ROM).Maximal isometric external and internal rotator strength of the hip muscles and bilateral leg extension strength were measured by dynamometers. Active (AROM) and passive (PROM) range of motion of the hip were measured by goniometers in 30 patients before and 3, 6 and 12 months after hip resurfacing. Postoperatively the patients were advised to return to their usual physical activities.Prior to the surgery internal rotation strength was on the same level on both sides, whereas external rotation strength of the operated hip was 26% (p0.001) lower compared with the unoperate…
Osteoarthritis Increases the Risk of Cardiovascular Disease: Data from the Osteoarthritis Initiative
2018
Objectives: Although osteoarthritis (OA) is a common condition in older adults, the role of OA in increasing cardiovascular disease (CVD) incidence is still debated. The aim of this study was to investigate the association between OA and the onset of CVD in a large database of American adults. Design: Longitudinal. Setting: Community-dwelling. Participants: People with OA or at high risk of OA. Measurements: Osteoarthritis was defined as the presence of OA of the hand, knee, hip, back/neck or of other sites. CVD was defined as self-reported presence of heart attack, heart failure, stroke and other cerebral atherosclerotic conditions, and peripheral artery disease. Results: A total 4,265 per…
Genetic, clinical and radiographic signs in knee osteoarthritis susceptibility
2014
Abstract INTRODUCTION: Osteoarthritis (OA) is considered to be a multifactorial and polygenic disease and diagnosis is mainly clinical and radiological. Correlation between radiographic data and clinical status has been reported. However, very few studies, especially in Caucasian people, describe the association between the Kellgren and Lawrence OA grading scale (KL) and genetic alterations to better understand OA etiopathogenesis and susceptibility. In order to update the knee OA grading, in this study we assessed the associations between KL grade, clinical features such as American Knee Society Score (AKSS), age, and polymorphisms in the principal osteoarthritis susceptibility (OS) genes …
External rotation strength deficit after hip resurfacing surgery.
2008
The aim was to assess the effect of resurfacing hip arthroplasty on hip muscle function, when, in the posterior approach, the piriformis tendon and outer rotators of the hip joint were divided. The unoperated side was used as a control.Thirty-three consecutive patients (mean age 55 years, 73% males) were operated using the posterior approach. Main outcome measures were isometric muscle strength of external and internal rotators and extensors of the hip and hip pain.Hip external rotation strength (p0.001) and leg extension strength (p0.001) were significantly lower on the operated side compared with the un-operated side prior to the surgery. On the operated side external rotation strength de…
Statin Use and Knee Osteoarthritis Outcomes: A Longitudinal Cohort Study
2018
Objective: Statins have several pleiotropic effects, but the literature regarding the possible relationship between use of statins and outcomes in knee osteoarthritis (OA) is limited. The aim of this study was to investigate whether statin use is associated with a lower risk of radiographic OA (ROA), radiographic symptomatic knee OA, and pain in North American individuals. Methods: A total of 4,448 community-dwelling adults from the Osteoarthritis Initiative were followed for 4 years. Statin use (including the time from baseline and the type of statin) was defined through self-report information and confirmed by a trained interviewer. Knee OA outcomes included incident ROA, symptomatic knee…
Loading and gait symmetry during level and stair walking in asymptomatic subjects with knee osteoarthritis: importance of quadriceps femoris in reduc…
2007
Repetitive impulsive forces during walking are claimed to result in joint osteoarthritis (OA). The aim of this study was to investigate impact loading and gait symmetry during level and stair walking in asymptomatic elderly subjects with knee OA. It was hypothesised that pre-activity of the quadriceps femoris muscle (QF) would be an important factor reducing impulsive loading when walking on level ground. Subjects [21 female, six men, 66.2 (7.6) years] were studied. The subjects had no knee pain or diminished functional capacity, but showed radiographically light or moderate bilateral knee OA changes. Ground reaction forces (GRFs), plantar pressure distribution, muscle activation pattern [v…
Physical Function and Properties of Quadriceps Femoris Muscle in Men With Knee Osteoarthritis
2008
To examine the objective physical function of the lower extremities, to measure the properties of quadriceps femoris muscle (QFM), and to assess subjective disabilities in men with knee osteoarthritis (OA) and to compare the results with those obtained from age- and sex-matched control subjects.Cross-sectional study.Rehabilitation clinic in a university hospital.Male volunteers (n=54) (age range, 50-69y) with knee OA and randomly selected healthy, age- and sex-matched control subjects (n=53).Not applicable.Physical function evaluated with a test battery including the QFM composition measurement, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the RAND 36-Item…
Prospective associations of cardiovascular disease with physical performance and disability
2019
Background: Literature regarding cardiovascular disease (CVD) and incident physical performance limitations and disability in older people is equivocal. Aims: This study aimed to investigate whether CVD is longitudinally associated with incident physical performance limitations and disability in a large population-based sample. Methods: This was an 8‑year prospective study using data collected as part of the Osteoarthritis Initiative. Participants were community-dwelling adults with knee osteoarthritis or at high risk for this condition. Diagnosed CVD was self-reported. Physical performance was assessed with measures of chair stand time and gait speed, whereas disability was assessed with t…
The ceiling effects of patient reported outcome measures for total knee arthroplasty
2020
Abstract Background Patient reported outcome measurements (PROMs) that exhibit a substantial ceiling effect show clustering of participant's scores towards the upper limit of a scale and consequently have low discriminatory power among high end scores. This study aimed to compare ceiling effects at 1 and 2 years postoperatively across commonly usedPROMs for TKA. Hypothesis We hypothesized, that the analyzed PROMs differ substantially in regards to their ceiling effect. Patients and methods Patients that underwent a primary unilateral TKA and completed pre-operative and post-operative questionnaires were included in the analysis. Participants completed the KOOS, KOOS-12, KOOS-JR, KOOS-PS, WO…
