ABSTRACT:
An abrasion resistant prosthetic ligament or tendon includes a strap-like element formed of a stable biocompatible material which is attached at opposite ends to a patient. Attached to the strap-like element are one or more protective layers having sacrificial areas which are positioned in areas where abrasion between the prosthetic ligament and the patient's bones is anticipated. The sacrificial areas can be substantially abraided before any significant loss of strenth occurs, because the sacrificial areas are non-load-bearing, and protect the strap-like element from abrasion.
