Cranial Cruciate Ligament Rupture

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.

Cranial Cruciate Ligament Rupture

Objectives This study aimed to compare the under-and-over technique, a type of intracapsular treatment, and the standard fabella–tibial suture, a method for extracapsular treatment, in achieving immediate, postoperative stifle stability after cranial cruciate ligament (CrCL) rupture by using a feline, custom-made limb-press model. Methods Cadaveric feline hindlimb specimens (n = 14) were positioned in the limb press at predefined joint angles (stifle joint: 120°; hock joint: 120°), and vertical loads of 5%, 10%, 20% and 30% body weight were applied statically. Mediolateral radiographic views were obtained of the stifles under each load before and after CrCL transection, as well as after treatment with either of the two surgical techniques, and differences in distance between two predefined radiographic points for each radiograph were analysed. Results The general linear model showed a significant effect of load ( P <0.01) and technique ( P = 0.004) and a significant interaction between load and technique ( P = 0.006) regarding craniocaudal stifle stability. Distances between predefined tibial and femoral reference points were consistently higher in transected CrCLs than in intact stifles. All standard fabella–tibial suture-treated stifles (n = 7) were stable at all loads tested. Of the seven under-and-over technique-treated stifles, one was unstable at 20% body weight load and three at 30% body weight load. Conclusions and relevance Our model, which appropriately reproduced certain aspects of domestic shorthair cat stifle mechanics, indicated that a 40 lb monofilament nylon prosthesis, tightened at 20 N, produces more favourable biomechanical stabilisation of craniocaudal cruciate-related stifle instability than a 0.5 cm wide strip of fascia lata applied intracapsularly.

SummaryBiomechanical analysis of the contribution of extracapsular tissues to the stability of normal and cranial cruciate ligament-deficient stifle joints was done using a five degree of freedom test apparatus which allowed quantification of tibial translation. In joints without periarticular tissue, the intracapsular graft technique used achieved joint stability similar to that of the normal cranial cruciate ligament. Our results indicate that the periarticular tissues did not significantly add to the post-operative stability of the stifle after intracapsular reconstruction.

SummaryObjectives: To survey the current management of cranial cruciate ligament rupture in small dogs (<15 kg) by veterinarians.Methods: A questionnaire was distributed to veterinarians attending the British Veterinary Orthopaedic Association Spring meeting and British Small Animal Veterinary Association Annual Congress which took place in April 2010. Respondents were surveyed on their management of small dogs with cranial cruciate ligament ruptureResults: Immediate surgical management was chosen by 15.5% of the respondents. Following that, 77.6% of respondents suggested that case management would depend on severity of lameness (81%), age (72.6%), bodyweight (70.4%), degree of instability (64.8%), and duration of lameness (64.0%). Conservative management included non- steroidal antiinflammatory drugs (91.1%), short leash walks (91.1%), weight loss (89.0%), hydrotherapy (53.6%), physiotherapy (41.9%), and cage rest (24.2%). Where surgical management was chosen, 71.4% would perform the procedure rather than refer it to another practice. Surgical techniques included extra-capsular stabilisation (63.4%), corrective osteotomies (32.9%), and intra-articular stabilisation (6.8%). The demographic characteristics of the responding veterinarians had no effect on their initial management of the case. General practice veterinarians were less likely to perform a corrective osteotomy than to refer the case, but were no less likely to perform an extracapsular technique.Clinical significance: Conservative management is still widely used for treatment of cranial cruciate ligament rupture in dogs weighing less than 15 kg; this is in agreement with previous publications on the management of this condition in small dogs.

Extracapsular technique with lateral fabellar suture (LFS) is one of the commonest surgical techniques for canine cranial cruciate ligament (CRCL) rupture. Among LFS methods, parallel double holes in the tibia are the most effective for the repair of canine stifle joint. The aim of this study was to evaluate the effectiveness of two-hole LFS for canine CRCL rupture. We retrospectively evaluated the outcome of canine CRCL rupture treated with two-hole LFS technique performed by two surgeons from October 2011 to September 2013. Breeds included Beagle (n=5), Yorkshire terrier (n=5), German shepherd (n=4), and so on. Mean body weight was 14.0±11.6 kg (&gt;10 kg: n=16, &lt;10 kg: n=22). Body condition score (5 scales) was as follows: 1 (n=0), 2 (n=1), 3 (n=18), 4 (n=18), and 5 (n=1). There were 18 males [neutered (n=11)] and 20 females [spayed (n=12)]. Mean age was 83.4±44.8 months (&gt;12 months: n=35, &lt;12 months: n=3). The type of rupture was partial (n=17) and complete (n=21). The affected site was right (n=20), left (n=18), and bilateral (n=4). Rehabilitation after operation was needed in 8 cases. There were 12 cases of previous medial patellar luxation operation, and 6 cases of opposite site CRCL surgery. Start of weight bearing and resolution of extension function was on day 1 (n=30), day 2 (n=0), and after day 2 (n=8). There was no evidence of surgical site infection/inflammation in any cases. The results of this study showed that two-hole LFS is an easy and effective technique for the repair of canine CRCL.

Cranial Cruciate Ligament Rupture

SummaryThe effect of two suture types, monofilament polybutester and braided polyester, on stifle joint biomechanics after extra-articular repair of cranial cruciate ligament rupture was evaluated by analysis of the instant centre of motion. The instant centres of motion and resulting velocity vectors were determined radiographically on both stifles of eight fresh canine cadavers before and after cranial cruciate ligament transection. After ligament transection, all 16 stifles were repaired with an extra-articular technique utilizing a double strand of suture placed between the lateral fabella and the tibial tuberosity. One stifle on each cadaver was repaired with each suture type. The instant centres of motion and resulting velocity vectors were re-evaluated post repair. All stifles had normal instant centres of motion prior to transection of the cranial cruciate ligament. Neither ligament transection nor extra-articular repair with either suture type resulted in an abnormal change in the instant centre of motion.
