| dc.description.abstract | Objective: To characterize the effect of the Ruby Joint Stabilization System (Ruby) on the motion of the cranial cruciate ligament (CrCL) deficient stifle. To compare the motion with the Ruby to that of the CrCL-intact and CrCL-deficient stifle. Study Design: Each canine pelvic limb was mounted in a loading jig under 30% body weight. Motion data was collected using an electromagnetic tracking system at stifle angles of 125o, 135o and 145o with the CrCL-intact, CrCL-deficient and the Ruby applied. Results: Total translation of the CrCL-deficient stifle following the Ruby was reduced, but remained greater than the CrCL-intact stifle at angles of 125o, 135o and 145o. Internal rotation of the Ruby groups was greater than the CrCL-intact group at 145o, but not 125o and 135o. Varus motion of the Ruby group was decreased compared to the CrCL-deficient group, but increased compared to the CrCL-intact group at angles of 125o, 135o and 145o. Conclusion: Total translation and internal rotation of the CrCL-deficient stifle following the Ruby differed from that of the CrCL-intact stifle. However, the Ruby reduced total translation and internal rotation of the tibia relative to the femur in the CrCL-deficient stifle to levels that may yield clinically acceptable results. | en |
| dc.description.abstractgeneral | Cranial cruciate ligament disease is a common pathology of the canine stifle. Loss of this ligament results in instability of the stifle that results in pain and osteoarthritis, and can lead to damage of other intra-articular structures like the menisci. An abundant number of surgical procedures are described, with the goal of surgery being the restoration of normal stifle stability and function. A common surgical procedure for treatment is the lateral suture technique, which is an extracapsular method of stabilization. This procedure faces many complications; however, it remains a popular choice of stabilization due to its lower cost and less invasive nature. The Ruby Joint Stabilization procedure is a method of extracapsular repair that aims to restore stifle stability and circumvent several complications that plague the lateral suture. This cadaveric study sought to investigate how stifle motion of the normal canine stifle compared to that of the cranial cruciate ligament deficient stifle with the Ruby Joint Stabilization System applied. The results of this investigation demonstrated that the Ruby Joint Stabilization System adequately restored stifle motion to a level that could yield clinically acceptable results, as was demonstrated in a previously published clinical investigation of this technique. | en |
