Abstract
Hamstring tendons are commonly used for Anterior Cruciate Ligament (ACL) reconstruction. In our series of 100 consecutive Hamstring ACL reconstructions, a four-strand graft was less than 7.0 mm in 5 patients. The aim of this study was to develop a screening test to assess the size of the hamstring tendon and so aid in the pre operative planning and patient counselling especially if hamstring size was deemed to be inadequate. A retrospective study of 100 consecutive hamstring ACL reconstructions analysed the correlation of the tendon size to height, weight and body mass index. A prospective double blind study was also set up involving independent observations by a musculoskeletal radiologist and the lead Orthopaedic surgeon.
Result
There was no correlation between the anthropometric measures and hamstring size in the retrospective study. A total of 27 limbs were assessed sonographically, in 26 patients. Spearman's rank correlation coefficient was found to Pearson's r = 0.0786; p = 0.715.
Conclusion
Pre-operative anthropometric measures and Ultrasound could not be used as a screening test to detect inadequate hamstrings in the clinical setting.
