Prediction of length and diameter of hamstring tendon autografts for knee ligament surgery in Caucasians.

Purpose: Prediction of hamstring tendon autograft size facilitates preoperative planning of knee ligament surgery and may reduce the need for allografts in complex knee reconstructions. The aim of this study was to analyse whether length and diameter of hamstring tendon autografts can be predicted preoperatively with anthropometric parameters and patient characteristics.

Methods: In this observational study, 725 consecutive Caucasian patients scheduled for ACL reconstruction were included.

Regeneration of hamstring tendons after anterior cruciate ligament reconstruction.

Purpose: Primary aim of the study was analysis of hamstring tendon regeneration after anterior cruciate ligament reconstruction (ACLR). Secondary aim was analysis of isokinetic muscle strength in relation to hamstring regeneration. The hypothesis was that regeneration of hamstring tendons after ACLR occurs and that regenerated hamstring tendons contribute to isokinetic hamstring strength with regeneration distal to the knee joint line.
