Cranial Cruciate Ligament Rupture Repair in Dogs (An Experimental Study)

Abstract

The stifle joint is one of the most complex joints, the cranial cruciate ligament plays a major role in its stabilization and function. Cranial cruciate ligament rupture is considered one of the most common orthopedic injuries in dogs. Regarding to the surgical repair with CrCLR, there is more than one way to surgical deal with CrCLR cases, therefore, this study was designed to compare between LFS, over the top and TPLO techniques to choose the best one depending on the use of different diagnostic tools. In this study, dogs managed with TPLO technique appeared to provide better early limb function, a more rapid return to weight-bearing (2 months) in comparison with LFS and over-the-top methods (3-4.5 months). One of the results of this study that LFS repair relies on periarticular fibrous and scar tissue formation which plays the main role in stifle joint stabilization. On the other side, it turned out that the stability of the stifle joint in over-the-top technique depends on substituting the CrCL with intra-articular graft “autograft, fascia-lata”. TPLO technique achieves stability by decreasin
