Abstract: A locating anchor for a replacement ligament is described. The anchor comprises a bar which is operable to extend across the opening of a bone tunnel through which the replacement ligament passes. The bar has a number of characterising features. The bar may not include any lateral support, the bar may be recessed, the bar may have a fixing groove, preferably, for ligament sutures or fixing means may be provided at each end of the bar to fix the ends of the bar in the bone surrounding the tunnel opening. A method of fixation is also defined. The bar is particularly useful in avoiding hindrance to the surgeon caused by the necessity to thread sutures through the fixation device.
