Title

Comparative Pull-Out and Cyclic-Loading Strength Tests of Anchorage of Hamstring Tendon Grafts in ACL Reconstruction

Reference

American Journal of Sports Medicine. 1999. 27 (5), 621 - 625

Summary

Pull-out strength testing of 4 anchors in bovine tibia and femurs (stirrup, clawed washer, soft titanium screw and round-headed (RCI) screw). Stirrup is best.

Critique

Stirrup in tibia and others in femur. Mixture of inside-out and outside -in for screws.

Title

Cross-Pin femoral fixation: A new technique for hamstring ACL reconstruction of the knee

Reference

Arthroscopy. 1998. 14 (3), 258 - 267

Summary

Hamstring looped over pin passed transversely across femoral tunnel - stronger than interference screw and nearer joint than other techniques.

Critique

Combination of pullout testing in porcine femurs and clinical trial. No cyclic load testing of animal implants. High complication rate in patients - lateral migration of pin in 2/22, ITB irritation by screw head in 2/22, tibial metal removed in 2/22.
