RESUMO
INTRODUCTION: Knee ostheochondritis dissecans is an osteochondral disease, whose treatment is still debated. The purpose this study was to analyze the patients attached with bioabsorbable nail, assisted by arthroscopy. MATERIAL AND METHOD: Analysis was performed using median and interquartile range (P25-P75), with a follow-up of 9 patients (10 knees) operated for stage III osteochondral lesions. After a minimum of 12 months, the KOOS, IKDC, satisfaction questionnaires were evaluated and a MR control was perfomed. RESULTS: Bone healing was observed in 80% of patients in the first year, with a delay in union in 20%. The median for age was 15 years. The average follow-up was 5.93 years. All cases were located in the internal condyle. The OCD lesions did not show comminution or necrosis. The 40% of stable lesions, according to preoperative MR, were unestable in arthroscopy and it were attached with internal nail. Two groups of osteochondral lesions were differentiated: juvenile OCD (60%) and adult OCD (40%); all of them were stage III lesions. IKDC questionnaire results were an improvement of 29.5 (22.25, 37.52). In the KOOS questionnaire, an improvement was obtained in symptoms of 18.07, in pain of 29.12, in daily living 25.53, in function (sports, recreational activities) of 35 and in quality of life of 34.42. CONCLUSIONS: The bioabsorbable nail is a valid, reproducible option for unestable lesions with lesion integrity, with great improvement in function, quality of life and with few complications.
RESUMO
Although it has been pointed out that the main cardiovascular risk factors in diabetic are dyslipidemias, hypertension, and cigarette smoking, very few studies have analyzed other risk factors, such as sedentarism and maximal aerobic capacity (VO2 max). The purpose of this study was to evaluate VO2 max and blood lipids (total cholesterol = TC, high density lipoproteins cholesterol = HDL; low density lipoproteins cholesterol = LDL; triglycerides = TG), in 19 diabetics subjects, 19 sedentary and 19 long distance runners. The diabetics of 5-10 years of evolution were non obese (body fat < 28%), and in regular metabolic control (Hb A1 < 12%). The athletes had more than five years of uninterrupted training. The diabetics had significantly lower VO2 max, than the other groups. The mean +/- SEM (mL/kg/min) in diabetics was 30.5 +/- 1.6 versus 41.3 +/- 2.3 in the controls and 54.2 +/- 2.5 in the athletes. There were significant group differences in TG (218 +/- 44 in diabetics vs 106 +/- 16 in controls and 94 +/- 10 mg/dL in athletes) and in HDL (27.3 +/- 4.3 in diabetes versus 34.1 +/- 4.3 and 43.9 +/- 6.3 mg/dL). These data suggest that sedentarism and low VO2 max may be important risk factors in diabetics. An aerobic program for them could perhaps change their blood lipids favorably as their VO2 max was significantly correlated with TG (r = -0.45), HDL (r = 0.52) and the TC/HDL ratio (r = -0.57).
