“…The ability to predict the length of the hamstring graft preoperatively is of great importance and may help the surgeon in the decision to achieve an acceptable diameter for the autograft in ACL reconstruction. This study demonstrated a positive correlation between the patient height and thigh length with semitendinosus and gracilis graft length; this positive correlation was also reported in previous literatures [14][15][16][17].…”

Purpose Pre-operative knowledge of hamstring graft size for anterior cruciate ligament reconstruction (ACL) is of clinical importance and useful in making appropriate decisions about graft choice. This study investigated if there is any correlation between anthropometric measurements such as height, weight, body mass index, thigh length, and circumference with the size of hamstring tendon graft in anterior cruciate ligament reconstruction. Methods The anthropometric data of 50 consecutive adult males, who underwent primary ACL reconstruction using quadruple hamstring autograft, were collected prospectively. Data analysis using Pearson's correlation test was performed and multiple logistic regression analysis was used to investigate any correlation not detected by Pearson's test and to eliminate confounders. Results Patient's height and thigh length demonstrated a positive correlation with gracilis graft length (r = .464, P = .001, r = .456, P = .001, respectively) and semitendinosus graft length (r = .541, P = 000, r = .578, P = .000, respectively). While the patient's age was the only independent factor which had a positive correlation with the quadrupled hamstring graft diameter (r = .412, P = .004), multiple regression analysis showed abdominal girth had a significant negative correlation with gracilis (P = .04) and semitendinosus (P = .006) graft thickness. Conclusion This study demonstrated that some anthropometric measurements had a positive correlation with the hamstring graft length and diameter in male patients. Hence, these results provide preliminary support for the use of some anthropometric measurements in the preoperative planning and prediction of the hamstring graft length and diameter in anterior cruciate ligament reconstruction.

“…As a result, many study groups have attempted to find ways to predict the diameter of a two-or four-strand hamstring autograft prior to surgery. 18,[23][24][25][26] The patients in this study who underwent ACLR with a hamstring autograft had an average hamstring tendon diameter of 7.5 mm, compared with 9.1 mm among the hybrid graft cohort. In fact, it was not possible to match patients from both groups based on graft diameter within 0.5 mm.…”

Clinical Outcomes Following Primary Anterior Cruciate Ligament Reconstruction with Hamstring Autograft versus Planned Hybrid Graft

Few studies have compared outcomes between autografts versus hybrid grafts (combination of autograft and allograft) for anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to compare revision rate and patient-reported outcomes following primary ACLR with a hamstring autograft versus a preoperatively planned hybrid autograft-allograft. At a minimum 2-year follow-up, patients who had undergone primary ACLR with a double-stranded semitendinosus and gracilis hamstring autograft (A) or a planned hybrid (H) graft (single-strand semitendinosus with nonirradiated peroneus longus or tibialis posterior allograft) were contacted to fill out a survey containing the Knee Injury and Osteoarthritis Outcome Score (KOOS), Subjective International Knee Documentation Committee (IKDC) score, Single Assessment Numeric Evaluation (SANE), 12-Item Short-Form Health Survey (SF-12), and visual analog scale (VAS) for activity level prior to injury and at follow-up. From this collection of patients, a matched-pair comparison was made between groups, with patients matched by gender, age at the time of surgery, and follow-up time. Revision rate at follow-up was 8.4 and 2.4% in the A and H groups, respectively ( = 0.073). A total of 148 surveys were completed (83 A, 65 H), from which 36 matched pairs were formed. Within the matched pairs, average age at surgery did not differ significantly between groups (A: 35.7 years, H: 36.0 years, = 0.23). Time to follow-up was 4.3 and 3.7 years in the A and H groups, respectively. Patients with a hybrid graft had significantly higher KOOS Quality of Life subscores (A 69.6, H 79.2, = 0.028), subjective IKDC scores (A 72.6, H 79.7, = 0.031), and SANE scores (A 83.2, H 91.4, = 0.015) at follow-up. Otherwise, no significant differences were found in patient-reported outcome scores between groups. A preoperatively planned hybrid graft, with use of a fresh-frozen, nonirradiated allograft, should be considered as a viable alternative for primary ACLR in older patients.

“…In clinical practice, the tension applied to the tendon graft ranges from 20 to 80 N, whereas other authors accomplish graft tensioning "by hand" [5,28,29]. The amount of force needed to tension a graft should be titrated according to the size and diameter of the tendons [30], and should vary when two tendons with different cross sectional areas are used together in the same construct.…”
