Prediction of the quadruple hamstring autograft thickness in ACL reconstruction using anthropometric measures

Abstract

Height can be used as a practical and accurate measurement to preoperatively predict quadruple hamstring graft diameter in male patients. Identification of possible hamstring tendon autograft insufficiency allows for preoperative determination of additional graft source possibilities, resulting in a more prompt surgical strategy.

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].…”

“…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. In Schwartzberg's study only the height fell out of favour in predicting graft diameter, and although Loo et al also rejected the predictive usefulness of height, theirs was an all Asian male population [13,15].…”

“…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].…”

Hamstring Autograft Size Can Be Predicted and Is a Potential Risk Factor for Anterior Cruciate Ligament Reconstruction Failure

“…To make analysis possible, we assessed the most commonly reported significant parameter, height, across all studies and found an overall correlation of 0.45 (P < .00001). 17,18,[29][30][31][32][33][34][35] Five of the 9 studies provided linear regression equations correlating height to graft diameter. These were used to create the average heightto-diameter correlations shown in Table 5.…”
