“…This allows for a compressive force to be placed on the stifle joint, which is more consistent with in-vivo weight-bearing during the stance phase. The peak-to-peak values in this study were similar to previous work (Choate et al, 2013). In addition, both peak-to-peak and cranial translation was consistent between pairs of stifles from the same dog and across all dogs.…”

“…Breed variation in CrCL volume and median grayscale estimations may exist. Use of a 100 N load for laxity testing was arbitrary, but similar to other work (Choate et al, 2013). Confirmation that this loading did not induce cruciate ligament damage would have helped to validate our results.…”

“…Previous studies reporting joint laxity values have used a mechanical testing fixture in which the tibia is constrained perpendicular to the actuator axis (Choate et al, 2013). With the stifle joint at 135°, cranial-caudal loads are applied to elicit motion.…”

Estimation of cranial cruciate ligament (CrCL) structural properties in client-owned dogs with incipient cruciate rupture would be advantageous. The objective of this study was to determine whether magnetic resonance imaging (MRI) measurement of normal CrCL volume in an ex-vivo canine model predicts structural properties. Stifles from eight dogs underwent 3.0 Tesla 3D MRI. CrCL volume and normalized median grayscale values were determined using 3D Fast Spin Echo (FSE) Cube and Vastly under-sampled Isotropic PRojection (VIPR)-alternative repetition time (aTR) sequences. Stifles were then mechanically tested. After joint laxity testing, CrCL structural properties were determined, including displacement at yield, yield load, load to failure, and stiffness. Yield load and load to failure (R2=0.56, P<0.01) were correlated with CrCL volume determined by VIPR-aTR. Yield load was also correlated with CrCL volume determined by 3D FSE Cube (R2=0.32, P<0.05). Structural properties were not related to median grayscale values. Joint laxity and CrCL stiffness were not related to MRI parameters, but displacement at yield load was related to CrCL volume for both sequences during testing (R2>0.57, P<0.005). In conclusion, 3D MRI offers a predictive method for estimating canine CrCL structural properties. 3D MRI may be useful for monitoring CrCL properties in clinical trials.

“…Extracapsular procedures such as fabellotibial sutures have gained popularity due to low cost and ease of execution (WILKE et al, 2005;SNOW et al, 2010;CABANO et al, 2011). Fabellotibial sutures can be performed with a wide range of suture materials, including nylon leader line (BURGESS et al, 2010;CHOATE et al, 2013).…”

Cranial cruciate ligament rupture (CCLR) is one of the most important orthopedic conditions in dogs, leading to joint instability, pain, osteoarthritis and eventually to meniscal injuries. Several surgical techniques have been described to reestablish joint stability following CCLR, including extracapsular procedures. This study compared the biomechanical effects of two extracapsular stabilization techniques (lateral fabello-tibial suture -LFTS, and modified retinacular imbrication technique -MRIT) using nylon leader line following experimental CCLR in cadaver dogs. Twenty canine cadaveric stifles were used. Joint stiffness, cranial and caudal tibial displacement were evaluated in 4 different experimental scenarios: intact stifle, stifle with CCLR, CCLR treated with lateral fabello-tibial suture (LFTS), and CCLR treated with modified retinacular imbrication technique (MRIT). Results: Mean cranial tibial displacement increased progressively from intact to MRIT, LFTS and CCRL stifles. MRIT resulted in less caudal drawer motion than LFTS. Joint stiffness did not differ significantly between LFTS and MRIT treated stifles. Conclusion: LFTS and MRIT increase joint stability but MRIT is more effective; however none of the techniques studied was able to restore original intact stifle stiffness. Clinical implications of the results presented remain to be determined but kinetic gait analysis studies are warranted to determine whether this biomechanical advantage translates into improved hind limb function in dogs.

ResumoA ruptura do ligamento cruzado cranial (RLCCr) é uma das principais afecções ortopédicas em cães e resulta na instabilidade do joelho, dor, desenvolvimento de osteoartrose, podendo também causar lesão de menisco. Com o intuito de restabelecer a estabilidade da articulação, muitas técnicas são utilizadas, dentre elas, as extracapsulares. O objetivo do presente trabalho foi realizar a avaliação biomecânica de duas dessas técnicas em 20 joelhos de cadáveres de cães utilizando-se fio de náilon leader line. Nestas peças foram avaliados a rigidez articular e o deslocamento tanto cranial quanto caudal da tíbia em quatro situações distintas: joelho íntegro; joelho com RLCCr e sutura fabelo-tibial lateral (SFTL); joelho com RLCCr e sutura fabelo-tibial lateral e medial (SFTLM); e por fim, o joelho com RLCCr sem as técnicas de estabilização. Houve diferença no deslocamento cranial entre todas as situações, sendo em ordem crescente, o joelho integro, com SFTLM, com SFTL e por fim, o joelho com RLCCr não estabilizado. Na comparação da presença de movimento de gaveta caudal a técnica de SFTLM apresentou menor deslocamento que a técnica de SFTL. Com relação à rigidez tanto cranial quanto caudal, as duas técnicas não apresentaram diferença. As duas técnicas testadas diminuem a instabilidade do joelho, sendo a SFTLM mais efetiva, e nenhuma delas restaurou a rigidez articular de um joelho íntegro. As implicações clínicas dos resultad...
