ABSTRACT
The aim of the present study was to evaluate biomechanical properties of tendon turnover repair in comparison to direct repair and Pulvertaft weave. A total of 48 sheep flexor tendons were assigned to eight groups comprising single or double tendon turnover repair, tendon turnover segment (without tenorrhaphy), direct repair or Pulvertaft weave. Tensile strength, stiffness and failure mechanisms were evaluated with a 500 N load cell. Turnover repair showed no significant difference in tensile strength to direct repair. Failure in turnover repair occurred largely at the site of tenorrhaphy due to suture pull-through or suture rupture. the increase in cross-sectional area after turnover repair was similar to that after direct repair, but less than after Pulvertaft weave. Tendon turnover offers tensile strength similar to direct repair with no associated increase in bulk. It provides a biomechanically secure and quicker alternative to tendon grafting for reconstructing tendon defects, without secondary donor site morbidity.Level of evidence V.
