  • Effect of meniscal damage on the development of frequent knee pain, aching, or stiffness
  • 2007
  • Ingår i: Arthritis and Rheumatism. - : Wiley. - 1529-0131 .- 0004-3591. ; 56:12, s. 4048-4054

    • OBJECTIVE: To evaluate the effect of meniscal damage on the development of frequent knee pain, aching, or stiffness in middle-aged and older adults. METHODS: The Multicenter Osteoarthritis Study is a prospective study of 3,026 individuals 50 years of age or older who have or are at high risk of developing knee osteoarthritis (OA). We investigated knees at baseline and at 15 months. Case knees (n = 110) were those with no pain, aching, or stiffness on most days at baseline, but that had developed frequent pain, aching, or stiffness at 15 months. Control knees (n = 220) were drawn randomly from knees with no frequent symptoms at baseline that did not become case knees. Using 1.0T magnetic resonance imaging performed at baseline and at followup, 2 musculoskeletal radiologists blinded to the case-control status assessed the meniscal damage using the following scale: 0 = intact, 1 = minor tear, 2 = nondisplaced tear or prior surgical repair, and 3 = displaced tear, resection, maceration, or destruction. The effect of meniscal damage was analyzed by contingency tables and logistic regression. RESULTS: Meniscal damage was common at baseline both in case knees (38%) and in control knees (29%). Although there was a modest association between the meniscal damage score (range 0-3) and the development of frequent knee pain, aching, or stiffness (odds ratio [OR] 1.21, 95% confidence interval [95% CI] 0.96-1.51, adjusted for age, sex, and body mass index), meniscal damage was mostly present in knees with OA. When considering the co-occurrence of OA, we found no independent association between meniscal damage and the development of frequent knee symptoms (OR 1.05, 95% CI 0.80-1.37). CONCLUSION: In middle-aged and older adults, any association between meniscal damage and the development of frequent knee pain seems to be present because both pain and meniscal damage are related to OA and not because of a direct link between the two.

  • Meniscal Tear in Knees Without Surgery and the Development of Radiographic Osteoarthritis Among Middle-Aged and Elderly Persons The Multicenter Osteoarthritis Study
  • 2009
  • Ingår i: Arthritis and Rheumatism. - : Wiley. - 1529-0131 .- 0004-3591. ; 60:3, s. 831-839
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. Although partial meniscectomy is a risk factor for the development of knee osteoarthritis (OA), there is a lack of evidence that meniscal damage that is not treated with surgery would also lead to OA, suggesting that surgery itself may cause joint damage. Furthermore, meniscal damage is common. The aim of this study was to evaluate the association between meniscal damage in knees without surgery and the development of radiographic tibiofemoral OA. Methods. We conducted a prospective case-control study nested within the observational Multicenter Osteoarthritis Study, which included a sample of men and women ages 50-79 years at high risk of knee OA who were recruited from the community. Patients who had no baseline radiographic knee OA but in whom tibiofemoral OA developed during the 30-month followup period were cases (n = 121). Control subjects (n = 294) were drawn randomly from the same source population as cases but had no knee OA after 30 months of followup. Individuals whose knees had previously undergone surgery were excluded. Meniscal damage was defined as the presence of any medial or lateral meniscal tearing, maceration, or destruction. Results. Meniscal damage at baseline was more common in case knees than in control knees (54% versus 18%; P < 0.001). The model comparing any meniscal damage with no meniscal damage (adjusted for baseline age, sex, body mass index, physical activity, and mechanical knee alignment) yielded an odds ratio of 5.7 (95% confidence interval 3.4-9.4). Conclusion. In knees without surgery, meniscal damage is a potent risk factor for the development of radiographic OA. These results highlight the need for better understanding, prevention, and treatment of meniscal damage.

  • Valgus Malalignment Is a Risk Factor for Lateral Knee Osteoarthritis Incidence and Progression Findings From the Multicenter Osteoarthritis Study and the Osteoarthritis Initiative
  • 2013
  • Ingår i: Arthritis and Rheumatism. - : Wiley. - 1529-0131 .- 0004-3591. ; 65:2, s. 355-362
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. To study the effect of valgus malalignment on knee osteoarthritis (OA) incidence and progression. Methods. We measured the mechanical axis from long limb radiographs from the Multicenter Osteoarthritis Study (MOST) and the Osteoarthritis Initiative (OAI) to define limbs with valgus malalignment (mechanical axis of >= 1.1 degrees valgus) and examined the effect of valgus alignment versus neutral alignment (neither varus nor valgus) on OA structural outcomes. Posteroanterior radiographs and knee magnetic resonance (MR) images were obtained at the time of the long limb radiograph and at followup examinations. Lateral progression was defined as an increase in joint space narrowing (on a semiquantitative scale) in knees with OA, and incidence was defined as new lateral narrowing in knees without radiographic OA. We defined lateral cartilage damage and progressive meniscal damage as increases in cartilage or meniscus scores at followup on the Whole-Organ Magnetic Resonance Imaging Score scale (for the MOST) or the Boston Leeds Osteoarthritis Knee Score scale (for the OAI). We used logistic regression with adjustment for age, sex, body mass index, and Kellgren/Lawrence grade, as well as generalized estimating equations, to evaluate the effect of valgus alignment versus neutral alignment on disease outcomes. We calculated odds ratios (ORs) and 95% confidence intervals (95% CIs). Results. We studied 5,053 knees (881 valgus) of subjects in the MOST cohort and 5,953 knees (1,358 valgus) of subjects in the OAI cohort. In both studies, all strata of valgus malalignment, including 1.1 degrees to 3 degrees valgus, were associated with an increased risk of lateral disease progression. In knees without radiographic OA, valgus alignment >3 degrees was associated with incidence (e. g., in the MOST, adjusted OR 2.5 [95% CI 1.0-5.9]). Valgus alignment >3 degrees was also associated with cartilage damage on MR imaging in knees without OA (e. g., in the OAI, adjusted OR 5.9 [95% CI 1.1-30.3]). We found a strong relationship of valgus malalignment with progressive lateral meniscal damage. Conclusion. Valgus malalignment increases the risk of knee OA radiographic progression and incidence as well as the risk of lateral cartilage damage. It may cause these effects, in part, by increasing the risk of meniscal damage.

  • Trends in 21st century Health Care Utilization in a Rheumatoid Arthritis Cohort Compared to the General Population
  • 2012
  • Ingår i: Arthritis and Rheumatism. - Hoboken, NJ : John Wiley & Sons. - 0004-3591 .- 1529-0131. ; 64:S10, s. S31-S32
  • Tidskriftsartikel (refereegranskat)abstract
    • Statement of purpose: To study twenty-first century trends in health care utilization by rheumatoid arthritis (RA) patients compared to the general population. Methods: Observational cohort study; using Swedish health care register data, we identified 3977 Region Skåne residents (mean age year 2001, 62.7 years and 73% women) consulting for RA (ICD-10 codes M05 or M06) in 1998-2001. We randomly sampled two referents from the general population per RA patient matched for age, sex, and area of residence. We calculated the year 2001-2010 trends for the annual ratio (RA cohort/referents) of the mean number of hospitalizations and outpatient clinic visits. Results: By the end of the 10-year period 62% of RA patients and 74% of referents were still alive and resident in the region. From 2001 to 2010 the ratio (RA cohort/referents) of the mean number of hospitalizations for men and women decreased by 27% (p=0.01) and 28% (p=0.004), respectively. The corresponding decrease was 29% (p=0.005), and 16% (p=0.004) for outpatient physician care, 34% (p=0.009) and 18% (p=0.01) for nurse visits, and 34% (p=0.01) and 28% (p=0.004) for physiotherapy (Figure 1 and 2). Figure 1.Health care utilization during the first decade of the twenty-first century by patients in a closed rheumatoid arthritis cohort and their matched referents from the general population. The y-axes show the mean number of visits per subject per calendar year. Figure 2.Health care utilization during the first decade of the twenty-first century by patients in a closed rheumatoid arthritis cohort and their matched referents from the general population. The y-axes show the mean number of visits per subject per calendar year. Conclusions: During the twenty-first century, coinciding with increasing use of earlier and more active RA treatment including biological treatment, the overall inpatient and outpatient health care utilization by a cohort of RA patients decreased relative to the general population.

  • The Associations Between Finger Length Pattern, Osteoarthritis, and Knee Injury: Data From the Framingham Community Cohort
  • 2011
  • Ingår i: Arthritis and Rheumatism. - : Wiley. - 1529-0131 .- 0004-3591. ; 63:8, s. 2284-2288
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. To investigate the associations of index finger-to-ring finger (2D:4D) length ratio with radiographic knee and hand osteoarthritis (OA), previous knee injury, and meniscal lesions in the general population. Methods. We measured the length of the right second and fourth phalangeal and metacarpal bones on hand radiographs from 1,020 randomly recruited subjects (ages 51-92 years). Knee radiography and magnetic resonance imaging (MRI) were performed on subjects. Women and men were divided into tertiles according to their 2D: 4D phalangeal and metacarpal ratios. We assessed the odds ratios (ORs) and 95% confidence intervals (95% CIs) for radiographic knee OA, severe symptomatic knee OA, radiographic hand OA, previous knee injury, and MRI-defined meniscal lesion, using logistic regression with adjustment for age and body mass index. Because hand OA may affect the 2D: 4D phalangeal ratio, we performed sensitivity analyses in subjects without joint space narrowing in the second and fourth interphalangeal joints. Results. We found no significant associations between 2D: 4D length ratio and radiographic knee OA, severe symptomatic knee OA, or meniscal lesions. Low 2D: 4D phalangeal ratio was associated with hand OA in women (OR 1.80, 95% CI 1.11-2.93), but in the sensitivity analysis, the association was attenuated (OR 1.35, 95% CI 0.79-2.32). Low 2D: 4D phalangeal ratios were associated with knee injury in men (OR 1.78, 95% CI 1.02-3.10). We found no significant associations for 2D:4D metacarpal ratios. Conclusion. Low 2D:4D phalangeal ratios in men are associated with knee injury, but we did not find any significant association with knee OA. Low 2D:4D length ratio may be a consequence, rather than a cause, of hand OA in women.
