Prospective cross sectional collection of data, Level IV.

Are pre-operative anthropometric parameters helpful in predicting length and thickness of quadrupled hamstring graft for ACL reconstruction in adults? A prospective study and literature review

“…We found that the anthropometric characteristics of our population (mean of height, weight, BMI and graft diameters in our study; 169.1±6.9 cm, 69.2±11.7 kg, 24.1±3.5 and 7.7±0.6 mm) are well matched to previous similar studies [11][12][13][15][16][17][18]. No study in the past has also shown a very strong correlation (R²<0.20) with any of the parameters when multiple stepwise regression analysis was performed [11,13,[16][17][18].…”

“…Tuman et al proposed the same threshold for height in their study which was Predicted diameter from equation may agree well with true diameter but with increased risk of over estimating thickness in up to 30 % cases followed up by Treme and colleagues, who further reduced the height for risk of graft less than 7 mm to 140 cm, although both mentioned that this remained more significant for females [11,12]. Ma et al [14] and Pinheiro et al [17] also noted height to be a factor affecting graft diameter for both men and women although women had significantly smaller grafts in their study compared to men and they did not propose a threshold of height for inadequate graft. The findings of Boisvert et al suggested a much taller population statistic with height less than 162.5 cm in women to be a risk for quadrupled graft less than 7 mm but they could not apply it in males; in contrast, Celiktas and colleagues [16,18] proposed 155.2 cm as a height threshold for the men in their study.…”

“…No study in the past has also shown a very strong correlation (R²<0.20) with any of the parameters when multiple stepwise regression analysis was performed [11,13,[16][17][18]. The most consistent parameter in most of these studies is the height [11][12][13][14][15][16][17][18]. In our data set we found the height to be significantly valuable (p<0.001) in predicting the graft diameter but the strength of this correlation was moderate (R²=0.128; explains 12.8 % variance in diameter due to height).…”

“…Studies in the past have thus attempted to predict pre-operatively the adequacy of such quadrupled hamstring graft. Pre-operative parameters such as age, gender, height, weight, BMI, leg length, thigh circumference, etc., have been reported to be of predictive value in a variety of studies but there is poor consensus [11][12][13][14][15][16][17][18]. Magnetic resonance, 3D tomography, and USG have also been employed to improve the accuracy of pre-operative prediction of hamstring tendon graft harvest data [19][20][21].…”

Clinicoradiological correlation between preoperative measurement of ACL footprint on MRI and intra operative semitendinosis graft diameter

“…[13] There are some studies that evaluated the graft thickness with the correlations of anthropometric characteristics of the patients. [3,[14][15][16] As an alternative method to anthropometric characteristics in preoperative evaluations, there are some studies based on quantitative analysis in the prediction of intraoperative graft size. And these studies focused on the correlation between CSA and diameter of hamstring tendon on preoperative MRI and intraoperative hamstring graft size.…”
