title: Is height the best predictor for adequacy of semitendinosus-alone anterior cruciate ligament reconstruction? A study of hamstring graft dimensions and anthropometric measurements.
abstract: To predict adequacy of semitendinosus (ST) graft dimension for ACLR from anthropometric measures.
  
  
  
  Single tendon harvest for autograft hamstring ACLR could be beneficial to limit donor site morbidity; however, concerns for reconstruction failure based upon inadequate graft size may limit this surgical technique.
  
  
  
  To predict adequacy, prospectively, 108 patients who underwent ACLR by hamstring graft (STG graft) were enrolled for the study. Mean age was 33.028 years ± 9.539 SD (14-59) with 88 males and 20 females. Anthropometric measurements (height, weight, BMI, thigh and total limb length) and intraoperative data (graft dimensions and bone tunnel measurements) were collected for analysis. Semitendinosus graft can be used as 3-strand (ST3) or 4-strand (ST4) graft. Adequacy criteria for ST3 and ST4 graft dimensions were determined from data analysis. SPSS (v.17) Pearson's correlation coefficient and ROC curves were used for statistical analyses.
  
  
  
  A total of 74 out of 108 patients (68.52 %) had adequate graft dimensions for ST3 reconstruction. Height equal or greater than 158 cm was predictive of adequate graft for ST3 reconstruction. Only 23 patients (21.3 %) had adequate graft dimensions for ST4 reconstruction. Height equal or greater than 170 cm was predictive of adequate graft for ST4 reconstruction. Height variable had the highest ROC curve area of 0.840 and 0.910 for both ST3 graft and ST4 graft, respectively. Hence, height was used as best predictor to determine adequacy of the graft.
  
  
  
  Height can be predictive of adequate graft for single tendon ACL reconstruction.
