Human ligament replacement
First Claim
1. A method of making a human ligament replacement including the steps of:
- (a) obtaining an animal tendon of appropriate thickness to function as a substitute for the particular human ligament to be replaced;
(b) cutting the tendon to an appropriate length as determined by the ligament to be replaced;
(c) immersing the tendon in a fixing solution for a sufficient length of time to bind the tendon tissue;
(d) wrapping the tendon with a protective covering; and
(e) passing absorbable sutures through the tendon to provide openings therein whereby after the tendon ends are grafted to the human bone portions formerly connected to the ligament being replaced and healing has begun, scar tissue can migrate into the openings left by the absorbable sutures to increase the strength and the securement of the tendon to said bone portions.

Abstract
The ligament replacement is obtained by taking a tendon from an animal of appropriate size to function as the substitute for the particular human ligament to be replaced. This tendon is cut to an appropriate length and immersed in a fixing solution such as glutaraldehyde for a sufficient length of time to bind the tissue. The tendon is wrapped in a protective covering and absorbable sutures are passed through the tendon to provide openings. After the tendon is grafted to the human portions formerly connected to the ligament to be replaced and healing has begun, scar tissue can then migrate into the openings left by the absorbable sutures to increase the strength and the securement of the tendon to the bone portions.

6. A human ligament replacement comprising, in combination:
-
(a) an animal tendon whose tissue has been bound by immersion in a fixing solution; (b) a protective covering wrapped about said tendon; and (c) absorbable sutures passing longitudinally through the tendon whereby after the tendon ends are grafted to the human bone portions formerly connected to the ligament being replaced and healing has begun, scar tissue can migrate into the openings left by the absorbable sutures to increase the strength and the securement of the tendon to said bone portions. - View Dependent Claims (7)
