[Prevalence and Distribution of Knee Cartilage Lesions in Sportspersons and Non-Sportspersons: Results of a Retrospective Arthroscopic Study.]
ABSTRACT Aim: This study was aimed to evaluate the correlation between sports activity and frequency and grad of non-traumatic knee cartilage lesions.Methods: A total of 868 patients (469 male and 399 female) who were suffering from knee pain (> 3 months) had undergone knee arthroscopy. The mean duration of history was 11.4 ± 11.5 (3 - 48) months. Criteria for exclusion were major knee injuries (e. g., ACL injuries). All cartilage lesions were classified according to the ICRS (International Cartilage Repair Society) guidelines and summarised with the semiquantitative WOAKS (Whole Organ Arthroscopic Knee Score). Results: There was a significant correlation between cartilage degeneration and age. Older female patients (63 to 85 years) demonstrated higher knee degenerations than male patients. The grade cartilage degeneration was higher in non-sportspersons (WOAKS = 13.5 ± 13.8) than in sportspersons (WOAKS = 7.1 ± 5.3), p < 0.001. Only in younger patients (17 to 34 years) was there no difference in the frequency of cartilage lesions in correlation to sports activity. A high-pivoting sport was significantly more frequently associated with cartilage degeneration in comparison to low-pivoting sports. Cartilage lesions most frequently occur within the mean bearing zones of the medial knee compartment. With regard to sports activity, no differences were observed in the distribution of cartilage lesions. Conclusions: Sportspersons who suffer from knee pain without injury have significantly less cartilage lesions or, respectively, severe cartilage defects. Cartilage lesions mostly occur within the medial knee compartment without correlation to sports activity and sport type. Patients who are performing "high-pivoting" sports more frequently are suffering from severe cartilage lesions than "low-pivoting" sportspersons. For a final epidemiological estimation of any correlations between sports and cartilage damage, longitudinal MRI studies are needed.

ABSTRACT: Thirty-seven million Americans suffer from some form of arthritis and the prevalence of arthritis among the elderly is particularly high. Therefore it is not surprising that there is a large new literature directed toward the epidemiology and health services for the older individual with arthritis. Many studies in osteoarthritis have refined the minutia or confirmed earlier work. Osteoarthritis increases with age and accounts for 46 million patient visits each year, with knee arthritis accounting for the most common complaint initiating such visits. Late stage rheumatoid arthritis has again been strongly associated with shortened life span, and factors predicting early death have been identified. Meanwhile, the "pyramid model" of rheumatoid arthritis treatment has been challenged. Of interest is the identification of obesity as a major risk factor for disability in elderly patients with arthritis and the fact that the incidence of hip fracture in the elderly, already known to be high, may be increasing. A provocative report suggests that mass screening for osteoporosis followed by selective treatment may be more cost effective than empirical treatment of all postmenopausal women.Current Opinion in Rheumatology 05/1992; 4(2):153-9.

ABSTRACT: To analyse the association of alcohol consumption and blood lipids, haemostatic factors, and homocysteine in German adults by gender and age groups. Cross-sectional population-based survey. Data from the German National Health Interview and Examination Survey 1998, representative for age, gender, community size, and federal state. From a sample of 7124 Germans between 18 and 79 y old, 2420 women and 2365 men were selected. Only individuals who were not currently receiving medical treatment or did not have disorders related to cardiovascular disease were selected for this study. Using analyses of variance, mean blood levels of total cholesterol, HDL cholesterol, HDL/total cholesterol ratio, total glycerides, fibrinogen, antithrombin III, and homocysteine adjusted for age, socioeconomic status, East/West Germany residence, body mass index, tobacco use, sports activity, and coffee consumption, if appropriate are presented by alcohol consumption groups (0, >0-10, >10-20, >20-30 and >30 g/day). The HDL/total cholesterol ratio increased with higher alcohol groups up to 10-20 g/day (+15%) for women and >30 g/day (+18%) for men, showing the strongest rise among men aged 55-79 y. Fibrinogen decreased with higher alcohol groups up to 10-20 g/day for women and 20-30 g/day for men. Among women, homocysteine levels showed a U-shaped curve with a minimum of 8.49 mmol/l at 10-20 g alcohol/day (-8%, reference: nondrinking), whereas an inverse association was observed for men. Moderate alcohol consumption is associated with favourable levels of several cardiovascular risk factors. The most favourable cardiovascular risk factor profile among women was observed among those drinking 10-20 g alcohol/day. Beneficial effects seem to be more pronounced among older men.European Journal of Clinical Nutrition 05/2004; 58(4):605-14. DOI:10.1038/sj.ejcn.1601854 · 2.95 Impact Factor
