[The sheep: an animal model for ligament prostheses?].
Ruptures of the anterior cruciform ligament is difficult to repair. Ligament prostheses are sometimes useful. We tested a ligament prosthesis which had the original property of combining a polyester braid with a matrix favouring collagen ingrowth. We implanted this prosthesis in the knee joint of 10 sheep after sectioning the anterior cruciform ligament at it origin. The ligaments were recovered after 6 months. We studied the functional and radiographic results. Tolerance was studied in samples of the articular fluid and synovial tissue. We evaluated bone attachment and fibrous growth using micro-radiography and specific coloration techniques. Samples were examined under electron microscope. No rupture was encountered. We observed a satisfactory functional and radiographic result. No intolerance was observed. The neoligament had a bony or mixed attachment in 60% of the cases and was comprised of oriented tissue in 90% of the cases. Vascular invasion was important. These findings are promising and suggest that long-term studies should be undertaken.
