Efficacy of interference screw and double-docking methods using palmaris longus and GraftJacket for medial collateral ligament reconstruction of the elbow.
Single-strand elbow medial collateral ligament reconstruction strength was evaluated by use of double-docking and interference screw methods with either a palmaris longus tendon or GraftJacket as the reconstruction material. Thirteen upper extremities were mounted in 90 degrees of valgus orientation and subjected to cyclic valgus loading that increased progressively until failure occurred. The double-docking reconstructions outperformed the interference screw reconstructions (P < .05), whereas the palmaris longus and GraftJacket performed comparably (P > .05). The favorable initial strength of the GraftJacket make it a potentially viable alternative to the use of autogenous palmaris longus tendons; however, further studies are required to evaluate graft strength during healing. The clinical use of the double-docking technique of single-strand medial collateral ligament reconstruction should be considered because of its simplicity and initial strength.
