Investigation of knee joint stability in surgically repaired canine cruciate ligament ruptures by cyclic passive joint motions

Abstract The cranial cruciate ligament (CCL) rupture is a prevalent injury in dogs. A consequence of instability the affected knee joint. veterinary, mostly surgical treatment usually unavoidable. suitability an arthroscopic method with replacement material was investigated. stability joint determined several times during 1,200 passive robotic motion cycles movement radius between 90° flexion and 140° extension. condition measured by triggering drawer test. After 300 cycles, test could be triggered (positive test). In following up to also triggered. However, no significant differences occurred these tests. showed damage loosening after first results that developed promising approach for ruptures canines.
