ABSTRACT: To compare the anthropometric data and the sportive way of life with the hamstring tendons dimensions, prospectively, in order to create a rule to predetermine its dimensions. General and anthropometric data were collected from 30 patients that were submitted to anterior cruciate ligament reconstruction. These data were correlated to the diameter and length of the hamstring tendons. The data collected were: height, weight, age, knee lesion side, body mass, sportive training level, femoral length, tibia length, thigh circumference, and knee circumference. The correlation was made by Pearson coefficient. Statistic significant correlation occurred only with height and tibia length versus the gracilis and semitendinous tendon length. Using linear regression the relations found could be expressed with the following formulas: semitendinous length = -2.276 + 0.177 x height; semitendinous length = 13.048 + 0.46 x tibia height; gracilis length = -9.413 + 0.207 x height; gracilis length = 7.036 + 0.583 x tibia height. It is possible to predetermine hamstring tendons length through linear regression formulas before surgical intervention.Revista do Colégio Brasileiro de Cirurgiões 08/2010; 37(4):274-8.

ABSTRACT: To evaluate the difference of the mechanical behavior of bended tied (sewed) and not tied hamstring tendons in order to evaluate if it has any effective function. Twenty-four fresh bovine digital tendons had been used. Alginate to determine the area of the tendon transversal section was used. Ten bovine tendons had been bended and tied following the manufacturer orientation, ten others pairs had not been tied. Claws had been developed for the grafts fixation to the universal machine, for the setting simulation. The superior one was characterized to be bipartite and to have controlled passage for the pins and the inferior claw is characterized to have alternating teeth. The maximum load of the not tied samples of the test was 849,4 N +/- 386,8 the area was 30,4 mm(2) +/- 7,7, and 29 +/- 17 Mpa of tension. The tied ones had gotten maximum load of 871,8 N +/- 484,9, area of 35 mm(2) +/- 5,8, and 24 +/- 10 Mpa of tension. It did not have statistical difference between the two groups (p>0,05). The probability distribution showed that with 400 N the not tied tendons represents 83,8% of trustworthiness and the tied ones represents 78,5%.Revista do Colégio Brasileiro de Cirurgiões 02/2010; 37(1):52-7.
